FORWARD In March 2001, the National Institutes of Health issued the following warning: "The number of Web sites offering health-related resources grows every day. Many sites provide valuable information, while others may have information that is unreliable or misleading."1 Furthermore, because of the rapid increase in Internet-based information, many hours can be wasted searching, selecting, and printing. Since only the smallest fraction of information dealing with ionized calcium is indexed in search engines, such as www.google.com or others, a non-systematic approach to Internet research can be not only time consuming, but also incomplete. This book was created for medical professionals, students, and members of the general public who want to know as much as possible about ionized calcium, using the most advanced research tools available and spending the least amount of time doing so. In addition to offering a structured and comprehensive bibliography, the pages that follow will tell you where and how to find reliable information covering virtually all topics related to ionized calcium, from the essentials to the most advanced areas of research. Public, academic, government, and peer-reviewed research studies are emphasized. Various abstracts are reproduced to give you some of the latest official information available to date on ionized calcium. Abundant guidance is given on how to obtain free-of-charge primary research results via the Internet. While this book focuses on the field of medicine, when some sources provide access to non-medical information relating to ionized calcium, these are noted in the text. E-book and electronic versions of this book are fully interactive with each of the Internet sites mentioned (clicking on a hyperlink automatically opens your browser to the site indicated). If you are using the hard copy version of this book, you can access a cited Web site by typing the provided Web address directly into your Internet browser. You may find it useful to refer to synonyms or related terms when accessing these Internet databases. NOTE: At the time of publication, the Web addresses were functional. However, some links may fail due to URL address changes, which is a common occurrence on the Internet. For readers unfamiliar with the Internet, detailed instructions are offered on how to access electronic resources. For readers unfamiliar with medical terminology, a comprehensive glossary is provided. For readers without access to Internet resources, a directory of medical libraries, that have or can locate references cited here, is given. We hope these resources will prove useful to the widest possible audience seeking information on ionized calcium. The Editors

CHAPTER 1. STUDIES ON IONIZED CALCIUM Overview In this chapter, we will show you how to locate peer-reviewed references and studies on ionized calcium.

The Combined Health Information Database The Combined Health Information Database summarizes studies across numerous federal agencies. To limit your investigation to research studies and ionized calcium, you will need to use the advanced search options. First, go to http://chid.nih.gov/index.html. From there, select the “Detailed Search” option (or go directly to that page with the following hyperlink: http://chid.nih.gov/detail/detail.html). The trick in extracting studies is found in the drop boxes at the bottom of the search page where “You may refine your search by.” Select the dates and language you prefer, and the format option “Journal Article.” At the top of the search form, select the number of records you would like to see (we recommend 100) and check the box to display “whole records.” We recommend that you type “ionized calcium” (or synonyms) into the “For these words:” box. Consider using the option “anywhere in record” to make your search as broad as possible. If you want to limit the search to only a particular field, such as the title of the journal, then select this option in the “Search in these fields” drop box. The following is what you can expect from this type of search: •

Effects of Aging on Serum Ionized and Cystosolic Free Calcium Source: Hypertension. 34(4 Part 2): 902-906. October 1999. Contact: Available from American Heart Association. 7272 Greenville Avenue, Dallas, TX 75231-4596. Summary: Calcium ions, both intracellular (within the cells) and extracellular (outside the cells) are critically important for a wide spectrum of cellular processes, including muscle contraction, nerve excitability, and stimulus to secretion coupling in all endocrine and exocrine tissues. Elevated cyctosolic free calcium (Cai) and reciprocally reduced, extracellular ionized calcium (Ca ion) levels are observed in both hypertension (high blood pressure) and type 2 diabetes. Because the changes of vascular (blood vessel) function and insulin sensitivity in these conditions resemble the changes

Ionized Calcium

associated with 'normal' aging, the authors of this article considered to what extent similar alterations in calcium metabolism occur with aging per se in the absence of overt hypertension or diabetes. This article reports on a study in which platelet Cai levels and serum C ion levels were measures in normotensive, nondiabetic, healthy, normal elderly (older than 65 years) subjects (n = 11); in 10 young adults with hypertension; and in 10 normotensive adults with type 2 diabetes. Platelet Cai levels were higher and Ca ion levels lower in normal elderly compared with young control subjects, but normal elderly Cai and Ca ion levels were indistinguishable from those in hypertensive and type 2 diabetes subjects. In normal subjects, significant correlations were found between platelet Cai levels and age, and between Cai levels and systolic blood pressure. The authors conclude that aging is associated with alterations of Cai and Ca ion levels resembling those changes present at any age in hypertension and type 2 diabetes. The authors hypothesize that these alterations of calcium metabolism underlie the predisposition to the alterations of blood pressure and insulin sensitivity characteristics of 'normal' aging. The data also suggest that studies of the aging process should be limited to subjects with normal blood pressure and glucose tolerance. 2 figures. 2 tables. 35 references. •

Modulation of Renal Calcium Handling by 11B-Hydroxysteroid Dehydroxysteroid Dehydrogenase Type 2 Source: JASN. Journal of the American Society of Nephrology. 13 (10): 2540-2546. October 2002. Contact: Available from Lippincott Williams and Wilkins. 12107 Insurance Way, Hagerstown, MD 21740. (800) 638-6423. Summary: Reduced concentration of serum ionized calcium and increased urinary calcium excretion have been reported in primary aldosteronism and glucocorticoid treated patients. This study considers whether inhibition of 11betaHSD2 (a type of dehydrogenase) by glcyrrhetinic acid (HA) may increase renal (kidney) calcium excretion. The results showed that inhibition of 11betaHSD2 activity is sufficient to significantly increase the fractional excretion of calcium and to decrease serum ionized calcium, suggesting decreased tubular reabsorption of this divalent cation under conditions of renal glucocorticoid or mineralocorticoid excess. The likely site of steroidregulated renal calcium handling appears to be the distal tubule. 4 figures. 1 table. 47 references.

Risk Factors and Risk for Mortality of Mild Hypoparathyroidism in Hemodialysis Patients Source: American Journal of Kidney Diseases. 39(6): 1245-1254. June 2002. Contact: Available from W.B. Saunders Company. Periodicals Department, 6277 Sea Harbor Drive, Orlando, FL 32887-4800. (800) 654-2452 or (407) 345-4000. Summary: Relative hypoparathyroidism (low levels of parathyroid hormone, PTH) is prevalent in patients on hemodialysis (HD), with unknown pathogenesis (how the disease develops) and prognosis. This article reports on a study undertaken to clarify the risk factors and prognosis of time-dependent relative hypoparathyroidism in HD patients. The retrospective study was performed for 126 HD patients with four or more PTH determinations and no previous total or subtotal parathyroidectomy. The prevalence of relative hypoparathyroidism at entry into the study was 76 of 126 patients (60.3 percent). Analysis showed that patients with hypoparathyroidism were older, more likely to have diabetes, and had greater ionized calcium levels and lower

phosphate, albumin, blood urea nitrogen (BUN), and creatinine levels. Patients with diabetes were older and had a shorter duration of dialysis therapy and lower PTH, phosphate, albumin, BUN, and creatinine levels and urea reduction ratios. Conversely, analysis also showed that PTH levels at entry were associated directly with creatinine levels and inversely with age and ionized calcium levels (but not diabetes). During follow up, PTH levels fluctuated concomitantly with ionized calcium and phosphate levels over time in all patients. The authors note that hypoparathyroidism at entry and lower time-dependent PTH levels predict mortality (death). 3 figures. 4 tables. 49 references. •

Severe Hyperphosphatemia and Hypocalcemia: A Dilemma in Patient Management Source: JASN. Journal of the American Society of Nephrology. 7(10): 2055-2061. October 1996. Summary: This article presents a case report of severe hyperphosphatemia and tetanic hypocalcemia resulting from the inadvertant oral ingestion of a phosphate enema. The physiology of serum phosphate regulation and the mechanism by which the elevation of serum phosphate is thought to induce hypocalcemia is discussed, and the treatment of hyperphosphatemia is reviewed. Finally, the authors consider the potential consequences of the administration of calcium to treat tetany in a patient with severe hyperphosphatemia. The authors conclude that, from a theoretical viewpoint, it seems prudent to give only enough calcium to control the cardiovascular consequences of hypocalcemia while delaying attempts to restore normal levels until after plasma phosphate concentration is controlled. However, when faced with a combination of acute, extreme exogenous hyperphosphatemia and hypocalcemia, as in this case study, the risk of metastatic soft tissue calcification in response to administration of calcium may be less important than restoration of at least a low-normal ionized calcium concentration. 1 figure. 2 tables. 31 references.

Foscarnet - Induced Hypocalcemia and Effect of Foscarnet on Calcium Metabolism Source: Journal of Clinical Endocrinology and Metabolism; Vol. 72, No. 5, May 1991. p. 1130-1135. Contact: University of California Positive Health Program, San Francisco General Hospital, AIDS Program, Clinical Research Section, PO Box 0881, San Francisco, CA, 94110-0881, (415) 514-0550. Summary: Toscarnet (trisodium phosphonoformate), an investigational pyrophosphate analog increasingly used to treat refractory cytomegalovirus retinitis and mucocutaneous herpes simplex virus infections in immunocompromised patients, has been reported to cause abnormalities in serum calcium and phosphate, including cases of fatal hypocalcemia. To further elucidate the magnitude and mechanism of these abnormalities in humans treated with foscarnet for opportunistic herpes virus infections, we analyzed anaerobic serum specimens and 24-h urine samples before and after single and multiple doses of iv foscarnet and performed a series of in vitro experiments with normal human serum and plasma. Plasma ionized calcium concentrations acutely decreased by a mean 0.17 mmol/L in the 6 individuals who received a 90 mg/kg dose of foscarnet and by a mean 0.28 mmol/L in the 11 individuals who received a 120 mg/kg dose (P = 0.016, 90 vs. 120 mg/kg dose). Results of in vitro experiments showed a highly significant inverse linear relationship between foscarnet and ionized calcium concentrations, but no correlation between foscarnet and total calcium or phosphate concentration. Dialysis experiments suggested that the

complexing of foscarnet with ionized calcium could be a cause of this ionized hypocalcemia. Physicians must be aware of this phenomenon and should measure serum ionized calcium during foscarnet therapy (preferably at the end of a foscarnet infusion) whenever neurological or cardiological abnormalities occur.

Federally Funded Research on Ionized Calcium The U.S. Government supports a variety of research studies relating to ionized calcium. These studies are tracked by the Office of Extramural Research at the National Institutes of Health.2 CRISP (Computerized Retrieval of Information on Scientific Projects) is a searchable database of federally funded biomedical research projects conducted at universities, hospitals, and other institutions. Search the CRISP Web site at http://crisp.cit.nih.gov/crisp/crisp_query.generate_screen. You will have the option to perform targeted searches by various criteria, including geography, date, and topics related to ionized calcium. For most of the studies, the agencies reporting into CRISP provide summaries or abstracts. As opposed to clinical trial research using patients, many federally funded studies use animals or simulated models to explore ionized calcium. The following is typical of the type of information found when searching the CRISP database for ionized calcium: •

Project Title: ALTERED CALCIUM AND VITAMIN D METABOLISM IN PMDD Principal Investigator & Institution: Thys-Jacobs, Susan; Assistant Professor; St. Luke'sRoosevelt Inst for Hlth Scis Health Sciences New York, Ny 100191102 Timing: Fiscal Year 2002; Project Start 01-APR-2000; Project End 28-FEB-2004 Summary: (adapted from investigator's abstract): Premenstrual Dysphoric disorder (PMDD) is widely recognized as a recurrent disorder related to hormonal variations of the menstrual cycle. PMDD shares many of the features of depression anxiety and the dysphoric states. Whereas alterations in calcium homeostasis have long been associated with many affective disturbances, recent evidence has suggested that luteal phase symptomatology may be associated with a perturbation in calcium homeostasis. Recently reported abnormalities in calciotropic hormone regulation, as well as the beneficial response to calcium treatment, all support the hypothesis that disordered calciotropic hormone regulation is a major provocative factor in luteal phase symptomatology. The purpose of the investigation is to understand more completely the extent to which calcium regulation is disturbed in PMDD by utilizing new tools to assess calcium and bone turnover. This investigation seeks to confirm our preliminary data in a definitive study. The long-term objective is to elucidate the pathophysiology of PMDD as it relates to the calciotropic hormones and bone markers. The experimental design involves enrolling 70 with PMDD and 35 controls. Following 2 months of baseline symptom documentation, women with PMDD and controls will be enrolled in a 1-month observational period with frequent hormonal samplings, urinary collections and daily ratings. Clinical evaluation will involve a detailed history and physical examination, a structured psychiatric interview and a dietary assessment. Hormonal

evaluation will include total and ionized calcium intact parathyroid hormone, 25 hydroxyvitamin D, 1,25 dihydroxyvitamin D, estradiol, progesterone, osteocalcin, urinary N-telopeptide, IGF-1 and TNF-A. Each subjects will be initially screened prospectively for 2 menstrual cycles with a daily, self assessment scale; symptoms will then be monitored and quantified for another 1 month while undergoing blood and urine sampling. The observation period will provide extensive characterization of the calciotropic hormones and biochemical markers of bone turnover across the menstrual cycle with simultaneous symptom ratings in women with PMDD and controls. Bone density evaluation will be performed as well on all subjects. Understanding the pathophysiology associated with PMDD may lead to effective therapeutic strategies to prevent the neuropsychiatric disturbances and abnormal calcium regulation that are characteristic of this disorder.

Project Title: CA2+-RECEPTOR: IMMUNE MODULATION IN VIVO AND IN VITRO Principal Investigator & Institution: Brown, Edward M.; Professor of Medicine; Brigham and Women's Hospital 75 Francis Street Boston, Ma 02115 Timing: Fiscal Year 2004; Project Start 01-APR-2004; Project End 31-MAR-2008 Summary: (provided by applicant): Autoimmunity is the cause of several common endocrine disorders. Graves' disease and nongoitrous hypothyroidism are examples of diseases caused by activating and inhibitory antibodies, respectively, to a G proteincoupled cell surface receptor (GPCR). The extracellular calcium-sensing receptor (CaR) is a GPCR that plays a crucial role in maintaining mineral ion homeostasis by virtue of its capacity to sense small changes in the extracellular ionized calcium concentration (Ca2+o). The physiological relevance of the CaR was established by the discovery of patients with activating or inactivating mutations that produce hypo- or hypercalcemic conditions, respectively. The former is termed autosomal dominant hypocalcemia (ADH) and the latter familial hypocalciuric hypercalcemia (FHH). Similar to inactivating or activating mutations, there might be patients with inactivating or activating antibodies to the CaR. Indeed, we recently described 4 patients with inactivating antibodies to the CaR, three of whom had a picture of FHH while one had biochemical findings more like primary hyperparathyroidism (PHPT). Surprisingly, further preliminary studies have identified inactivating antibodies in two individuals who had undergone removal of a parathyroid (PT) adenoma for a diagnosis of PHPT, raising the possibility that anti-CaR antibodies can contribute to the development of PHPT in a subset of patients. Additional preliminary studies have also identified two hypocalcemic individuals with activating antibodies to the receptor, who have a biochemical picture compatible with hypoparathyroidism. The overall goal of this proposal is to document that activating and inactivating CaR antibodies can cause forms of hypoparathyroidism and PTH-dependent hypercalcemia, respectively, that should be distinguished from other causes of these disorders and may be amenable to specific CaR-based medical therapy. The following aims are addressed at achieving this goal: (1) To identify and characterize inactivating antibodies to the CaR in persons with PTH-dependent hypercalcemia. (2) To identify and characterize activating antibodies to the CaR in persons with hypoparathyroidism. (3) To develop an animal model of activating and/or inactivating antibodies by immunization with the CaR's extracellular domain. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Ionized Calcium

Project Title: INTESTINAL PERFUSION AND PERMEABILITY IN SEPSIS Principal Investigator & Institution: Fink, Mitchell P.; Professor and Chairman; Anesthesiology; University of Pittsburgh at Pittsburgh 350 Thackeray Hall Pittsburgh, Pa 15260 Timing: Fiscal Year 2002; Project Start 01-APR-1987; Project End 30-JUN-2004 Summary: (Adapted from the applicant's abstract). The long- term goal of this application is to elucidate the fundamental mechanisms responsible for intestinal barrier dysfunction in states associated with acute tissue hypoxia and/or inflammation. One unifying hypothesis is that derangements in cellular energy metabolism cause or contribute to alterations in epithelial barrier function in critical illness. Aim I is to study cytokine mediated repression of hypoxia-inducible factor-1 (HIF-1)-dependent adaptive epithelial responses to hypoxia during sepsis. HIF-1 is a transcription factor that regulates the expression of a number of genes associated with adaptive cellular responses to hypoxia. In preliminary studies, they demonstrated that HIF-1 DNAbinding activity is increased when cultured hepatocytes and enterocytes are incubated with a mixture of IFN-gamma and TNF under normoxia. However, these cytokines fail to induce the expression of a HIF-1-dependent luciferase reporter gene. More recently, these cytokines inhibit HIF-1-dependent reporter activity during hypoxia. The applicants hypothesize that (1) HIF-1 DNA-binding activity will increase in the liver and intestinal mucosa of septic animals; (2) adaptive cellular responses to hypoxia will be impaired in cells or tissues that have been exposed to a pro-inflammatory milieu (such as occurs in sepsis); (3) signaling initiated by IFN-gamma and TNF suppresses HIF-1induced gene expression by blocking the recruitment of CBP/p300 to hypoxia-inducible promoters. Aim II is to evaluate one potential way that an increase in cytosolic ionized calcium concentration, [Ca2+] i, could act to increase intestinal epithelial paracellular permeability. They previously showed that epithelial hyperpermeability caused by ATP depletion is dependent upon the resultant increase in [Ca2+] i. The mechanism(s) whereby increases in [Ca2+] i promote hyperpermeability are unknown. In Aim II they will conduct experiments to test the hypothesis that elevation of [Ca2+] i leads to activation of a calcium-dependent enzyme, myosin light chain kinase (MLCK), and thereby increases phosphorylation of the 20-kDa cytoskeletal protein, myosin light chain (MLC20), resulting in cytoskeletal contraction and epithelial hyperpermeability on that basis. Aim III is to investigate the effect of cytokines, hypoxia, or metabolic inhibition on the polarized basolateral-to-apical transport of complex carbohydrates and other hydrophilic compounds across the intestinal epithelium. These studies are prompted by preliminary data they have obtained, which indicate that a wide variety of compounds, including dextrans and various anionic dyes, are transported across rat colonic mucosa in the serosa-to-mucosa direction via a process that apparently is energy-dependent. Based on these findings, we hypothesize that that impaired barrier function in sepsis (or other forms of acute illness) may not just reflect increased passive permeation in the apical-to basolateral direction, but also decreased active pumping (scavenging) in the opposite direction.

Summary: (Applicant's Description): The overall goal of the K08 award is to permit Sarah Tannehill-Gregg, D.V.M. to devote full time for research training leading to a Ph.D. in experimental pathobiology, and for development into an independent scientist for a cancer in academia or biomedical research. Dr. Tannehill-Gregg has completed a residency in comparative pathology and one year of research training in the sponsor's laboratory. The research goals are to investigate the regulation of extracellular calcium and the role of transforming growth factor-beta in parathyroid hormone-related protein (PTHrP) expression and secretion by cancers of the lung. This will address an important medical question since PTHrP is expressed by many carcinomas and is responsible for inducing humoral hypercalcemia of malignancy. The action of TGFbeta may be a critical determinant in the overexpression of PTHrP by carcinomas and play an important role in the pathogenesis of cancer-associated hypercalcemia in human patients. The overall hypothesis to be tested is that TGFbeta production by lung carcinoma acts as an autocrine or paracrine against to stimulate PTHrP production by the carcinoma cells. Aim 1: Investigate expression of PTHrP, TGFbeta1-3 and TGFbeta receptors (I and II) and measure serum ionized calcium and PTHrP concentrations and urine excretion of calcium and phosphorus in humans with lung cancer. Aim 2: Investigate the regulation of PTHrP expression and secretion by TGFbeta in lung carcinomas in vitro using explant cultures from spontaneous human neoplasms and cultures of lung carcinoma cell lines. Aim 3: Investigate the molecular regulation of PTHrP mRNA steady state levels, stability, and alternate splicing by TGFbeta in vitro using lung carcinoma explants and cell lines. Dr. Tannehill-Gregg has developed preliminary data to support all three aims and a collaboration with Medical and Surgical Oncology to facilitate the in vivo studies. The cooperative efforts of Dr. Tannehill-Gregg, the sponsor, and co-investigators in the Department of Veterinary Biosciences, Comprehensive Cancer Center, James Cancer Research Hospital, Pulmonary Oncology and Thoracic Surgery Divisions, and Tissue Procurement Program at Ohio State University will provide a productive environment to complete this significant investigation. The studies will provide important new data on the function of PTHrP and TGFbeta in lung cancer in human patients.

Project Title: MAGNESIUM AS A NEUROPROTECTIVE AGENT FOR PEDIATRIC TBI Principal Investigator & Institution: Shaffner, Donald H.; Anesthesiology/Crit Care Med; Johns Hopkins University 3400 N Charles St Baltimore, Md 21218 Timing: Fiscal Year 2002; Project Start 25-SEP-2001; Project End 31-AUG-2004 Summary: (provided by applicant): The overall objective of this collaborative, multiinstitutional project is to provide preliminary information required for subsequent, fullscale clinical trials of novel therapies for children with severe traumatic brain injury (TBI). This study will contribute both pediatric safety data for a specific pharmacotherapy (magnesium sulfate) and demonstrate the applicability in children of novel methods for assessing the effects of such therapy on the neuronal extracellular environment (cerebral microdialysis). Magnesium has a good safety profile and is being tested in pilot studies of adults with stroke and subarachnoid hemorrhage for its neuroprotective potential. There are, however, no data regarding its safety or efficacy in children with TBI. Cerebral microdialysis is being used both clinically and in research settings directed to adult TBI, but has not been used in children. The following Specific

Ionized Calcium

Aims address these gaps: 1. to examine the safety of magnesium for children with severe traumatic brain injury and therefore potentially compromised cerebral perfusion; 2) to examine the short-term efficacy of magnesium in modifying molecular markers of secondary brain injury 3) to examine the feasibility of measuring longer-term efficacy using clinical outcomes (functional, neuropsychological, and behavioral measures) as well as indicators of the severity of structural injury by MRI at three months post-injury. We will implement a randomized, placebo-controlled trial of magnesium in children with severe TBI who require intensive care and intracranial pressure monitoring. Based on subject availability with proposed inclusion/exclusion criteria, 24 subjects will be randomized. Clinically-required intracranial pressure monitoring will be accompanied by placement of a microdialysis catheter for research purposes. Following baseline measurements, study drug at (magnesium or placebo) will be administered as a bolus of 0.2 mmol/kg followed by 24-hour infusion. Using hemodynamic variables, cerebral perfusion pressure will be monitored. In addition, transcranial doppler velocities and brain interstitial lactate and pyruvate levels will be used to assess effects on cerebral perfusion. Microdialysis will be used to assess brain interstitial levels of ionized magnesium, ionized calcium, excitatory amino acids, and nitric oxide byproducts. In addition blood magnesium and calcium levels (both ionized and total) will be obtained. Multiple validated psychometric measures and MRI evaluation of CNS lesion numbers and location will address Specific Aim 3. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •

Project Title: PILOT--STANNIOCALCIN-1 INFLAMMATION Principal Investigator & Institution: Sheikh-Hamad, David; Associate Professor; Baylor College of Medicine 1 Baylor Plaza Houston, Tx 77030 Timing: Fiscal Year 2003; Project Start 01-APR-2003; Project End 31-MAR-2008 Summary: Stanniocalcin-1 (STC1) is a calcium-regulating hcrmone in bony fish. It is produced and stored in the corpuscle of Stannius, an accessory organ to the kidney. Elevation of ionized calcium in the fish plasma induces synthesis and secretion of STC1 into the blood. Upon circulation in the gill, it inhibits calcium influx from the aquatic environment, while in the gut, it inhibits calcium uptake. T'he mammalian homologue of this hormone is produced in multiple organs and is thought to function in an autocrine and/or paracrine manner. The cumulative data suggest that it inhibits calcium flux in cardiomyocytes, glut epithelium and neuronal cells. In neuronal cells, it is upregulated following ischemic injury and appears to have a cytoprotective effect in a manner that requires inhibition of calcium flux into the cells. Recent findings from our laboratory revealed striking upregulation of STC1 in the proximal tubules following ischemic or obstructive renal injury in humans. In addition, STC1 protein decorated the plasma membrane of inflammatory cells in the injured tissue. These findings suggested the involvement of STC1 in tissue inflammation, indeed, STC1 attenuated MCP1mediated intracellular calcium increas and chemotaxis (using a trans-filter assay) in the macrophage-like Raw264.7 cells. The following specific aims are intended to elucidate the molecular mechanisms that underlie this process. Specific Aim I: will test the hypothesis that STC1 inhibits chemotaxis in other mononuclear cells (lymphocytes) in a manner that involves alterations in intracellular calcium currents. Specific Aim II: will examine the hypothesis that STC1 is an anti-inflammatory molecule. This will be tested using STC1 in an in vivo model of rat (WKY) anti-GBM (glomerular basement membrane) glomerulonephritis. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Project Title: ROLE OF THE PLASMA MEMBRANE CALCIUM PUMP IN HEARING Principal Investigator & Institution: Penniston, John T.; Professor; Mayo Clinic Coll of Medicine, Rochester 200 1St St Sw Rochester, Mn 55905 Timing: Fiscal Year 2002; Project Start 01-SEP-2000; Project End 31-AUG-2004 Summary: (Adapted from the Investigator's Abstract) Ionized calcium (Ca2+) acts as an intracellular signal which is essential to hearing. To manage this signal, Ca2+ channels and pumps are necessary. Recent studies have shown that the plasma membrane Ca2+ pump (PMCA), which is highly concentrated in the tips of the stereocilia, is the sole Ca2+ extrusion system in hair cells. Knockout mice lacking isoform 2 of the PMCA are deaf and show severe balance deficits. Mice of strains named "deafwaddler" and "wriggle," which have similar deficits, have recently been found to be homozygous for a mutation in the same PMCA2 gene. Based on these findings, the proposal will explore the functional properties and specific interacting proteins of the major PMCA isoform(s) of the inner ear. The specific aims are (1) to determine which PMCA ioforms and alternative splice variants are expressed in rodent cochlea and vestibular hair cells; (2) to determine the functional properties of the major "deafwaddler" and "wriggle" PMCA mutants and of additional single amino acid mutants; and (3) to identify and characterize the proteins that interact with the major PMCA ioform of the hair cells, which may be responsible for its unique localization to the stereocilia tips. These experiments will establish a new area of investigation into the role of the plasma membrane Ca2+ pump as the controller of local Ca2+ regulation in the inner ear and should lead to a better appreciation of its contribution to the process of hearing.

CHAPTER 2. NUTRITION AND IONIZED CALCIUM Overview In this chapter, we will show you how to find studies dedicated specifically to nutrition and ionized calcium.

Finding Nutrition Studies on Ionized Calcium The National Institutes of Health’s Office of Dietary Supplements (ODS) offers a searchable bibliographic database called the IBIDS (International Bibliographic Information on Dietary Supplements; National Institutes of Health, Building 31, Room 1B29, 31 Center Drive, MSC 2086, Bethesda, Maryland 20892-2086, Tel: 301-435-2920, Fax: 301-480-1845, E-mail: [email protected]). The IBIDS contains over 460,000 scientific citations and summaries about dietary supplements and nutrition as well as references to published international, scientific literature on dietary supplements such as vitamins, minerals, and botanicals.7 The IBIDS includes references and citations to both human and animal research studies. As a service of the ODS, access to the IBIDS database is available free of charge at the following Web address: http://ods.od.nih.gov/databases/ibids.html. After entering the search area, you have three choices: (1) IBIDS Consumer Database, (2) Full IBIDS Database, or (3) Peer Reviewed Citations Only. Now that you have selected a database, click on the “Advanced” tab. An advanced search allows you to retrieve up to 100 fully explained references in a comprehensive format. Type “ionized calcium” (or synonyms) into the search box, and click “Go.” To narrow the search, you can also select the “Title” field.

Adapted from http://ods.od.nih.gov. IBIDS is produced by the Office of Dietary Supplements (ODS) at the National Institutes of Health to assist the public, healthcare providers, educators, and researchers in locating credible, scientific information on dietary supplements. IBIDS was developed and will be maintained through an interagency partnership with the Food and Nutrition Information Center of the National Agricultural Library, U.S. Department of Agriculture.

CHAPTER 5. PATENTS ON IONIZED CALCIUM Overview Patents can be physical innovations (e.g. chemicals, pharmaceuticals, medical equipment) or processes (e.g. treatments or diagnostic procedures). The United States Patent and Trademark Office defines a patent as a grant of a property right to the inventor, issued by the Patent and Trademark Office.8 Patents, therefore, are intellectual property. For the United States, the term of a new patent is 20 years from the date when the patent application was filed. If the inventor wishes to receive economic benefits, it is likely that the invention will become commercially available within 20 years of the initial filing. It is important to understand, therefore, that an inventor’s patent does not indicate that a product or service is or will be commercially available. The patent implies only that the inventor has “the right to exclude others from making, using, offering for sale, or selling” the invention in the United States. While this relates to U.S. patents, similar rules govern foreign patents. In this chapter, we show you how to locate information on patents and their inventors. If you find a patent that is particularly interesting to you, contact the inventor or the assignee for further information. IMPORTANT NOTE: When following the search strategy described below, you may discover non-medical patents that use the generic term “ionized calcium” (or a synonym) in their titles. To accurately reflect the results that you might find while conducting research on ionized calcium, we have not necessarily excluded nonmedical patents in this bibliography.

Patents on Ionized Calcium By performing a patent search focusing on ionized calcium, you can obtain information such as the title of the invention, the names of the inventor(s), the assignee(s) or the company that owns or controls the patent, a short abstract that summarizes the patent, and a few excerpts from the description of the patent. The abstract of a patent tends to be more technical in nature, while the description is often written for the public. Full patent descriptions contain much more information than is presented here (e.g. claims, references, figures, diagrams, etc.). We will tell you how to obtain this information later in the chapter.

Clinical testing apparatus Inventor(s): Schwartz; Henry D. (935 Waverly St., Palo Alto, CA 94301) Assignee(s): none reported Patent Number: 3,994,171 Date filed: December 15, 1975 Abstract: The testing apparatus is preferably for the measurement of ionized calcium and other ions in biologic fluids. The apparatus comprises a selectively operated turntable defined by a plurality of radially extending leaves fixed in position at one end along a circular locus, a cover overlying the turntable, and a plurality of sample cups carried by the turntable and each received by and positioned at the free end of one of the leaves. The leaves flex sufficiently to provide a bias on the cup urging the top edge of the cup into intimate contact with the bottom surface of the cover. The cover is at least partially hollow forming a plenum chamber for a saturated gas such as carbon dioxide and having a number of outlet jets spaced along a circumference of the cover with each jet for directing a flow of the gas into the cup at a suitable velocity to produce a good mixing and swirling action in the cup. In addition to the plenum mixing holes there is also an independent mixing hole at the probe station where a probe assembly comprising one or more probes is selectively and sequentially registered with the cups. The cover may also be provided with one or more sensor holes disposed outside of the mixing hole at the probe station. One sensor hole may have means associated therewith to permit introduction of an alternative gas to the cup at the probe station when this hole is blocked by a cup of special shape having a larger outside diameter. The other sensor hole may have means associated therewith to identify the cup at the probe station as containing a particular type of sample. By selection of the proper configuration of cup one can effectively program operation of the apparatus. Excerpt(s): The present invention relates in general to a clinical testing apparatus. More particularly, this invention pertains to a testing apparatus for making multiple sample clinical determinations of ionized calcium concentrations or other ions in body fluids. My copending application Ser. No. 320,264 shows a testing apparatus providing these multiple samplings. Although this apparatus operates quite satisfactorily it is an object of the present invention to provide an improved clinical testing apparatus which is preferably for making multiple sample clinical determinations of original ionized calcium concentrations of body fluids. Another object of the present invention is to provide an improved turntable type apparatus for performing a multiple sampling. Web site: http://www.delphion.com/details?pn=US03994171__

Patents 73

Abstract: Clinical testing means for determining pH dependent body fluid substances. In vivo ionized calcium concentration is obtained by withdrawing a blood specimen, determining the pH of the serum when withdrawn from the body and later, determining the in vivo ionized calcium concentration at the original pH. The pH of the serum is adjusted to the original pH by equilibration with carbon dioxide after which the ionized calcium concentration is directly electrically measured. Alternately, the original ionized calcium concentration is extrapolated or interpolated by making two different pH adjustments, electrically measuring calcium ion concentration, graphing the points obtained on semi-log paper to form a straight line graph from which the original calcium ion concentration can be obtained knowing the original serum pH. In still another variation, an extrapolation can be made to determine the carbon dioxide adjustment required to produce the original pH, after which pH adjustment the original concentration can be directly measured. Other variations of the methods are used to obtain less reliable but useful ionized calcium concentrations. A relationship between ionized calcium and total calcium in serum is used to determine total calcium levels. Multiple sample serum testing means has a rotatable sample container turntable and a cover means through which carbon dioxide can be simultaneously introduced into plural samples. The sampling means carries pH determining means and ionized calcium determining means for rapid ionized calcium measurements. Excerpt(s): For many years the medical profession has used clinical testing to determine total human serum calcium concentration in connection with diagnosis and treatment of various disease of the body including parathyroid disorders, tetany and bone structure diseases. Total calcium concentration of the serum includes both bound calcium and ionized or disassociated calcium. More recently, it has been recognized that the ionized calcium level is of significance in diagnosis and treatment of certain human malfunctions such as the diseases noted above. Knowing the total calcium concentration of a person, which can be measured by conventional means does not enable one to know the level of ionized calcium of that person. Thus, direct methods of measuring ionized calcium are desirable. It has been difficult to clinically measure human serum ionized calcium concentrations of the body by conventional clinical laboratory procedures. However, one apparatus for directly determining ionized calcium concentration in protein-containing liquids such as blood serum has been developed and is the Orion Ionalyzer Serum Calcium Activity Flow-Through System such as model 99-20 (Orion Research, Inc., Cambridge, Mass. U.S.A.). This system, as is known, basically uses two or three aqueous standards of known ionized calcium concentration which are flowed in turn through a calcium electrode with the millivoltage produced being recorded. The millivoltage is plotted against the logarithm of the ionized calcium for each standard to produce a calibration graph. Blood serum sample millivoltage is then similarly measured and by means of the calibration graph its ionized calcium concentration extrapolated manually or automatically by an electrical calculator such as an Olivetti 101. Thus, a method of directly measuring ionized calcium in a sample is available. However, certain problems arise in making useful and practical clinical determinations. When blood is withdrawn from its in vivo state in the body, its original pH in the body changes as time of exposure to air progresses. Thus, if ionized calcium is measured directly after withdrawal of the blood from a patient, reasonably accurate original or body serum ionized calcium concentration is obtained. However, such immediate measurement is often not practical because of distances between patients and the clinical laboratory as well as the volume of determinations to be made, shortages of personnel and the like.

Ionized Calcium

Control for blood gas/calcium analysis instrumentation Inventor(s): Chiang; Ching (Acton, MA) Assignee(s): Bionostics Incorporated (Acton, MA) Patent Number: 4,945,062 Date filed: June 15, 1988 Abstract: A liquid control standard for the use in the qualilty assurance of blood analysis instrumentation systems is disclosed. The liquid control standard is able to act as a control standard for blood gas instrumentation systems measuring pH, pCO.sub.2 and pO.sub.2 of blood, as a liquid control standard for ion selective electrode instrumentation systems for the measuring of electrolytes such as ionized calcium and total calcium as well as Na, K and Li ions in the blood and, optionally, as a control standard for a co-oximeter measuring the amount of total hemoglobin present in the blood and the relative amounts of other hemoglobin fractions present in the blood. Excerpt(s): The measurement of total calcium in blood has been used in the clinical practice for many years for routine diagnosis by physicians. During the past several years, the measurement of ionized calcium (Ca.sup.++, free calcium ions) has been recommended to provide an indicator which is more effective than total calcium in cases such as hyperparathyroidism, pancreatitis, renal diseases, and hypocalcemia resulting from repeated blood transfusion, malignancy, and other causes. Furthermore, it is also thought that the simultaneous measurement of both total and ionized calcium is beneficial in the clarification of certain diagnosis. For example, in some clinical cases of multiple myeloma in which hypercalcemia becomes a severe complication, the total calcium in patients is highly elevated while their ionized calcium is normal. Therefore both total and ionized calcium measurements are needed to provide information for a proper diagnosis. Various instrumentation systems have been developed for the determination of both total and ionized calcium. In the recent past, these instruments have utilized ion-selective-electrodes (ISE) for calcium and other electrolyte measurements. In addition, there has been the development of blood gas analyzers to which electrolyte analysis capabilities have been included through the integration of ion selective electrodes with electrodes for measurement of pH, pCO.sub.2 and pO.sub.2. Furthermore, the capability for measuring a variety of other parameters (e.g., total hemoglobin, hematocrit, glucose) has also been included in some of these instruments.

Method for measurement of ionized calcium Inventor(s): Kayahara; Norihiko (Kanagawa, JP), Miike; Akira (Shizuoka, JP), Tadano; Toshio (Shizuoka, JP), Umemoto; Jun (Hyogo, JP) Assignee(s): Kyowa Medex Co., Ltd. (Tokyo, JP) Patent Number: 5,840,512 Date filed: April 3, 1996 Abstract: The present invention relates to a method for quantitatively determining ionized calcium in a sample by using a phospholipase, which comprises carrying out an enzyme reaction with the phospholipase in a buffer comprising a nitrogen heterocyclebinding sulfonic acid having a pK ranging 6.6 to 7.6 or a salt thereof.According to the

Patents 75

method of the invention, the amount of ionized calcium in a sample, such as serum, can be accurately determined. Excerpt(s): This invention relates to a method for measuring ionized calcium by using an enzyme. Calcium contained in blood can be classified into the three kinds of proteinbinding calcium, complexing calcium and ionized calcium. Among these, only ionized calcium is important in clinical tests and the amount of ionized calcium in blood is measured in a test for parathyroid functions, a cardiac operation and the like. As a method for selectively determining the amount of ionized calcium, the ion electrode method is known. However, this method requires much time for operation and cannot treat a large number of samples at one time. Therefore, it is not suitable for clinical tests. As a method for treating a large number of samples at one time, there have been disclosed a method for quantitatively determining calcium by using a phospholipid, phospholipase D and N-tris(hydroxymethyl)methyl-2-aminoethanesulfonic acid ›TES! buffer (Japanese Unexamined Patent Publication No. 62-195297 and EP486997A); a method for quantitatively determining calcium by using phosphorylcholine thioester, phospholipase A.sub.2 and Tris-maleic acid buffer (Japanese Unexamined Patent Publication No. 1-231896); a quantitative determination method by using calmodulin (Japanese Unexamined Patent Publication No. 62-36199); and a quantitative determination method by using pyruvate kinase (Japanese Unexamined Patent Publication No. 2-142498). However, selective determination of ionized calcium is impossible by these methods. Web site: http://www.delphion.com/details?pn=US05840512__ •

Method for measuring calcium Inventor(s): Mulholland; Linda M. (Stoughton, MA), Young; Chung C. (Natick, MA) Assignee(s): Nova Biomedical Corporation (Waltham, MA) Patent Number: 4,724,216 Date filed: November 8, 1985 Abstract: A releasing reagent for releasing, as ionized calcium, protein-bound calcium in a biological sample for measurement of the ionized calcium, together with any ionized calcium originally present in the sample, using a calcium ion specific electrode, the releasing reagent including monochlorocoacetate salt, formate salt, and formic acid, in concentrations sufficient to render the pH of the sample, when mixed with the reagent, in the range of 4.0 to 5.5. Also disclosed is a method of measuring calcium in a liquid sample using such a releasing reagent. Excerpt(s): This invention relates to the measurement of calcium using ion specific electrodes. In biological fluids calcium ordinarily exists both in the form of calcium ions (Ca.sup.++) , and calcium complexed with protein and, to a lesser extent, other complexing agents in the fluids. Ion selective calcium electrodes measure only ionized, and not complexed calcium, despite the fact that it would be desirable in some situations to measure, in addition to ionized calcium, "total" calcium, i.e., the sum of ionized and complexed calcium. It is known that complexed calcium can be released by lowering the pH of the sample containing the complexed calcium. The most efficient releasing of calcium (over 90% calcium released) is observed when a sufficient amount of a strong acid is added to the liquid to lower the pH below 3.0. Such a drastic lowering of pH, however, is inconsistent with optimal operation of conventional calcium electrodes.

Method of blending an anticoagulant Inventor(s): Mercereau; Steven F. (4911 W. Lake Dr., Conyers, GA 30208) Assignee(s): none reported Patent Number: 5,552,323 Date filed: August 3, 1994 Abstract: A blended heparin salt for use as an anticoagulant in a blood sample, which substantially eliminates a skew in a determined amount of ionized calcium imparted by the heparin in the blood sample. The blended heparin salt comprises a proportional blend of a zinc salt of heparin and a lithium salt of heparin the salts in a ratio of 1-to-afractional-value-less-than-one of the zinc salt of heparin to the lithium salt of heparin by weight based on the USP potency of the salts, the fractional value determined by the ratio of the zinc available per unit of USP potency in the zinc salt of heparin to a predetermined amount of zinc per USP potency to be provided by the blended heparin salt. Methods of blending the proportional amounts of the zinc salt and the lithium salt of heparin are disclosed. Excerpt(s): The present invention relates to anticoagulants for use with analysis of blood samples and mettles of blending anticoagulants. More particularly, the present invention relates to heparin salts and to methods of blending heparin salts. Medical evaluations typically rely on a variety of tests for determining physiological conditions of patients. One common test is known as electrolyte analysis. This test determines the percentages of several ionized minerals in samples of blood taken frown patients. These ionized minerals include calcium, sodium, and potassium. Other tests can determine the pH value of the blood as well as other physiological indicators. The blood samples are typically collected in sampling syringes. The samples taken from the patients often consist of about three milliliters of blood. Them are a number of sampling syringes known in the art for drawing and holding samples for testing. The samples of blood typically are moved to laboratories for testing and analysis shortly after being obtained from the patients. Testing preferably should occur within 30 minutes or less of the samples being drawn. Dissolved gases in the blood begin diffusing from the samples immediately. The blood begins to coagulate and bind the minerals in the fluidal blood together. Coagulation skews the test results because the bound minerals resist detection during the analysis which only detects the free ionized minerals in the fluidal blood. If some of the minerals are clotted out of the fluid, the analysis results in a false determination of mineral content percentages less than is actually present in the blood of the patients being tested. Such incorrect determinations can lead to mis-diagnosis, which may lead to injury to the patients. Web site: http://www.delphion.com/details?pn=US05552323__

Reference liquid Inventor(s): Christiansen; Torben F. (Holte, DK) Assignee(s): Radiometer A/S (Copenhagen, DK) Patent Number: 4,363,633 Date filed: June 24, 1980

Patents 77

Abstract: A reference liquid for calibration or quality control of instruments which determine ionized calcium and pH. The reference liquid contains both a particular calcium ion activity and a pH-buffer and can therefore be used for calibration of both the calcium-sensitive electrode and the pH-electrode in the instruments. The pH-buffer is a nitrogen-containing organic sulphonic acid and the salt of this acid, the acid having a pK in the range of 6.6-7.6. The reference liquid has an ionic strength of 0.15-0.17, a buffer capacity.beta. in the range of 0.04-0.10 and is packed in glass ampoules. Excerpt(s): The present invention relates to a reference liquid for calibration or quality control of instruments which are adapted to determine the content of ionized calcium in liquid samples. It is known that the activity or concentration of calcium ions in biological liquids is critical to many important biological processes. The content of ionized calcium in serum or plasma is of a special interest as it plays an important role in the total calcium metabolism. In recent years, calcium-sensitive electrodes have been provided which permit an exact and relatively simple determination of ionized calcium. An example of these electrodes is described in U.S. Pat. No. 3,932,233. This electrode comprises an internal reference system and a membrane adapted to be contacted with the liquid the calcium ion activity of which is to be determined. The membrane contains a calcium ion exchanger, e.g. calciumdi-(p-n-octylphenyl)-phosphate which, during use of the electrode, is in electrical contact with the internal reference which may, e.g., be a silver/silver chloride electrode. The other known electrodes for determining calcium ion activities are also based on the use of calcium ion exchangers. It is known that the content of ionized calcium in serum is pH-dependent, which is especially due to the fact that the binding of calcium to serum proteins is pH-dependent. For this reason it is important to determine the pH of a serum sample together with its calcium ion activity, either in order to report the measured set of calcium ion activity and pH or to perform a conversion of the calcium ion activity into the calcium ion activity which would be present in the sample at a predetermined "normal" pH, for example 7.40. The relation between ionized calcium and pH is discussed, e.g., by Moore in "The Journal of Clinical Investigation", volume 19, 1969, pages 318-334, and in U.S. Pat. No. 3,941,565. Therefore, the most suitable instruments for determining ionized calcium in biological liquids are instruments in which the liquid sample in which the content of ionized calcium is to be determined is measured both with a calcium-sensitive electrode and with a pHelectrode.

HCaRG, a novel calcium-regulated gene coding for a nuclear protein Inventor(s): Grossard, Francis; (Quebec, CA), Hamet, Pavel; (Quebec, CA), Lewanczuk, Richard; (Alberta, CA), Solban, Nicolas; (Quebec, CA), Tremblay, Johanne; (Quebec, CA) Correspondence: Banner & Witcoff; 1001 G Street N W; Suite 1100; Washington; DC; 20001; US Patent Application Number: 20020115604 Date filed: July 16, 2001 Abstract: This invention relates to a novel gene that shows tissue specific expression and increased expression in a low calcium concentration medium. Low renin hypertension is characterized by decreased levels of serum ionized calcium in the presence of increased levels of parathyroid hormone. It is hypothesized that hypertensive factor(s) are cosecreted with PTH in SHR, a model of low renin hypertension, the parathyroid hypertensive factor being one of them. As a negative calcium balance is present in spontaneously hypertensive rats (SHR), we searched for gene(s) involved in this dysregulation. A cDNA library was constructed from the SHR parathyroid gland which is a key regulator of serum ionized calcium. From 7 overlapping DNA fragments, a 1100-bp novel cDNA containing an open reading frame of 224 codons was reconstituted. This novel gene, named HCaRG (Hypertension-related, Calcium-regulated Gene), was negatively regulated by extracellular calcium concentration and its basal mRNA levels were higher in hypertensive animals. The deduced protein showed no transmembrane domain, 67% a helix content, a mutated calcium-binding site (EF-hand motif), 4 putative `leucine zipper` motifs and a nuclear receptor-binding domain. At the subcellular level, HCaRG had a nuclear localization. We cloned the human homolog of this gene. Sequence comparison revealed 80% homology between rats and humans at the nucleotide and amino acid sequences. Tissue distribution showed a preponderance in the heart, stomach, jejunum, kidney (tubular fraction), liver and adrenal gland (mainly in the medulla). HCaRG mRNA was significantly more expressed in adult than in fetal organs, and its levels were decreased in tumors and cancerous cell lines. We observed that after 60-min ischemia followed by reperfusion, HCaRG mRNA declined rapidly in contrast with an increase in c-myc mRNA. Its levels then rose steadily to exceed baseline at 48 h of reperfusion. HEK293 cells stably transfected with HCaRG exhibited much lower proliferation, as shown by cell count and 3 H-thymidine incorporation. Taken together, our results suggest that HCaRG is a nuclear protein potentially involved in the control of cell proliferation. Excerpt(s): The present invention relates to a novel gene that shows tissue specific expression and increased expression in a low calcium concentration medium and in hypertensive animals, and which is potentially involved in the regulation of cell proliferation. Calcium ion is an essential element of life with distinct extracellular and intracellular roles- Extracellular functions of calcium include its role in blood clotting, intercellular adhesion, bone metabolism, maintenance of plasma membrane integrity whereas its intracellular roles include protein secretion, cellular contraction and division. The free extracellular calcium concentration is maintained within a narrow range (.about.1 to 1.3 mM) and that of intracellular calcium is in the order of 100 nM; 10,000 fold lower than the extracellular free calcium concentration. The first priority of the extracellular calcium homeostatic system is to maintain a normal extracellular ionized calcium concentration. This component represents approximately 45% of the total circulating calcium concentration- Another 45% of total circulating calcium is bound to proteins (primarily albumin) and about 10% is Pound to small organic anion. Therefore, ionized calcium concentration in plasma is maintained within a very narrow

Patents 79

range. The major players maintaining extracellular calcium homeostasis are calciotropic hormones, parathyroid hormone (PTH), 1,25 dihydroxyvitamin D, calcitonin and calcium itself. Indeed, extracellular calcium regulates its own concentration as an extracellular messenger by acting on cells involved in the control of extracellular calcium homeostasis such as parathyroid, bone, intestine and kidney cells (56). For example, parathyroid cells are key sensors of extracellular calcium in vertebrates responding with increases in PTH secretion when there is a decrease in calcemia while high calcemia stimulates hormonal release of calcitonin from C cells of the thyroid gland.

Coffee Break: Tutorials for Biologists18 Coffee Break is a general healthcare site that takes a scientific view of the news and covers recent breakthroughs in biology that may one day assist physicians in developing treatments. Here you will find a collection of short reports on recent biological discoveries. Each report incorporates interactive tutorials that demonstrate how bioinformatics tools are used as a part of the research process. Currently, all Coffee Breaks are written by NCBI staff.19 Each report is about 400 words and is usually based on a discovery reported in one or more articles from recently published, peer-reviewed literature.20 This site has new articles every few weeks, so it can be considered an online magazine of sorts. It is intended for general background information. You can access the Coffee Break Web site at the following hyperlink: http://www.ncbi.nlm.nih.gov/Coffeebreak/.

Other Commercial Databases In addition to resources maintained by official agencies, other databases exist that are commercial ventures addressing medical professionals. Here are some examples that may interest you: •

CliniWeb International: Index and table of contents to selected clinical information on the Internet; see http://www.ohsu.edu/cliniweb/.

•

Medical World Search: Searches full text from thousands of selected medical sites on the Internet; see http://www.mwsearch.com/.

18 Adapted 19

from http://www.ncbi.nlm.nih.gov/Coffeebreak/Archive/FAQ.html.

The figure that accompanies each article is frequently supplied by an expert external to NCBI, in which case the source of the figure is cited. The result is an interactive tutorial that tells a biological story. 20 After a brief introduction that sets the work described into a broader context, the report focuses on how a molecular understanding can provide explanations of observed biology and lead to therapies for diseases. Each vignette is accompanied by a figure and hypertext links that lead to a series of pages that interactively show how NCBI tools and resources are used in the research process.

89

APPENDIX B. PATIENT RESOURCES Overview Official agencies, as well as federally funded institutions supported by national grants, frequently publish a variety of guidelines written with the patient in mind. These are typically called “Fact Sheets” or “Guidelines.” They can take the form of a brochure, information kit, pamphlet, or flyer. Often they are only a few pages in length. Since new guidelines on ionized calcium can appear at any moment and be published by a number of sources, the best approach to finding guidelines is to systematically scan the Internet-based services that post them.

Patient Guideline Sources The remainder of this chapter directs you to sources which either publish or can help you find additional guidelines on topics related to ionized calcium. Due to space limitations, these sources are listed in a concise manner. Do not hesitate to consult the following sources by either using the Internet hyperlink provided, or, in cases where the contact information is provided, contacting the publisher or author directly. The National Institutes of Health The NIH gateway to patients is located at http://health.nih.gov/. From this site, you can search across various sources and institutes, a number of which are summarized below. Topic Pages: MEDLINEplus The National Library of Medicine has created a vast and patient-oriented healthcare information portal called MEDLINEplus. Within this Internet-based system are “health topic pages” which list links to available materials relevant to ionized calcium. To access this system, log on to http://www.nlm.nih.gov/medlineplus/healthtopics.html. From there you can either search using the alphabetical index or browse by broad topic areas. Recently, MEDLINEplus listed the following when searched for “ionized calcium”:

Ionized Calcium

Bone Diseases http://www.nlm.nih.gov/medlineplus/bonediseases.html Kidney Diseases http://www.nlm.nih.gov/medlineplus/kidneydiseases.html Parathyroid Disorders http://www.nlm.nih.gov/medlineplus/parathyroiddisorders.html Sarcoidosis http://www.nlm.nih.gov/medlineplus/sarcoidosis.html You may also choose to use the search utility provided by MEDLINEplus at the following Web address: http://www.nlm.nih.gov/medlineplus/. Simply type a keyword into the search box and click “Search.” This utility is similar to the NIH search utility, with the exception that it only includes materials that are linked within the MEDLINEplus system (mostly patient-oriented information). It also has the disadvantage of generating unstructured results. We recommend, therefore, that you use this method only if you have a very targeted search. The NIH Search Utility The NIH search utility allows you to search for documents on over 100 selected Web sites that comprise the NIH-WEB-SPACE. Each of these servers is “crawled” and indexed on an ongoing basis. Your search will produce a list of various documents, all of which will relate in some way to ionized calcium. The drawbacks of this approach are that the information is not organized by theme and that the references are often a mix of information for professionals and patients. Nevertheless, a large number of the listed Web sites provide useful background information. We can only recommend this route, therefore, for relatively rare or specific disorders, or when using highly targeted searches. To use the NIH search utility, visit the following Web page: http://search.nih.gov/index.html. Additional Web Sources A number of Web sites are available to the public that often link to government sites. These can also point you in the direction of essential information.

IONIZED CALCIUM DICTIONARY The definitions below are derived from official public sources, including the National Institutes of Health [NIH] and the European Union [EU]. Abdomen: That portion of the body that lies between the thorax and the pelvis. [NIH] Abdominal: Having to do with the abdomen, which is the part of the body between the chest and the hips that contains the pancreas, stomach, intestines, liver, gallbladder, and other organs. [NIH] Acetylcholine: A neurotransmitter. Acetylcholine in vertebrates is the major transmitter at neuromuscular junctions, autonomic ganglia, parasympathetic effector junctions, a subset of sympathetic effector junctions, and at many sites in the central nervous system. It is generally not used as an administered drug because it is broken down very rapidly by cholinesterases, but it is useful in some ophthalmological applications. [NIH] Acidosis: A pathologic condition resulting from accumulation of acid or depletion of the alkaline reserve (bicarbonate content) in the blood and body tissues, and characterized by an increase in hydrogen ion concentration. [EU] Actin: Essential component of the cell skeleton. [NIH] Adenoma: A benign epithelial tumor with a glandular organization. [NIH] Adenosine: A nucleoside that is composed of adenine and d-ribose. Adenosine or adenosine derivatives play many important biological roles in addition to being components of DNA and RNA. Adenosine itself is a neurotransmitter. [NIH] Adjustment: The dynamic process wherein the thoughts, feelings, behavior, and biophysiological mechanisms of the individual continually change to adjust to the environment. [NIH] Adjuvant: A substance which aids another, such as an auxiliary remedy; in immunology, nonspecific stimulator (e.g., BCG vaccine) of the immune response. [EU] Adrenal Cortex: The outer layer of the adrenal gland. It secretes mineralocorticoids, androgens, and glucocorticoids. [NIH] Adrenergic: Activated by, characteristic of, or secreting epinephrine or substances with similar activity; the term is applied to those nerve fibres that liberate norepinephrine at a synapse when a nerve impulse passes, i.e., the sympathetic fibres. [EU] Aequorin: A photoprotein isolated from the bioluminescent jellyfish Aequorea. It emits visible light by an intramolecular reaction when a trace amount of calcium ion is added. The light-emitting moiety in the bioluminescence reaction is believed to be 2-amino-3-benzyl-5(p-hydroxyphenyl)pyrazine (AF-350). [NIH] Affinity: 1. Inherent likeness or relationship. 2. A special attraction for a specific element, organ, or structure. 3. Chemical affinity; the force that binds atoms in molecules; the tendency of substances to combine by chemical reaction. 4. The strength of noncovalent chemical binding between two substances as measured by the dissociation constant of the complex. 5. In immunology, a thermodynamic expression of the strength of interaction between a single antigen-binding site and a single antigenic determinant (and thus of the stereochemical compatibility between them), most accurately applied to interactions among simple, uniform antigenic determinants such as haptens. Expressed as the association constant (K litres mole -1), which, owing to the heterogeneity of affinities in a population of antibody molecules of a given specificity, actually represents an average value (mean

102

intrinsic association constant). 6. The reciprocal of the dissociation constant. [EU] Agar: A complex sulfated polymer of galactose units, extracted from Gelidium cartilagineum, Gracilaria confervoides, and related red algae. It is used as a gel in the preparation of solid culture media for microorganisms, as a bulk laxative, in making emulsions, and as a supporting medium for immunodiffusion and immunoelectrophoresis. [NIH]

Age of Onset: The age or period of life at which a disease or the initial symptoms or manifestations of a disease appear in an individual. [NIH] Agonist: In anatomy, a prime mover. In pharmacology, a drug that has affinity for and stimulates physiologic activity at cell receptors normally stimulated by naturally occurring substances. [EU] Albumin: 1. Any protein that is soluble in water and moderately concentrated salt solutions and is coagulable by heat. 2. Serum albumin; the major plasma protein (approximately 60 per cent of the total), which is responsible for much of the plasma colloidal osmotic pressure and serves as a transport protein carrying large organic anions, such as fatty acids, bilirubin, and many drugs, and also carrying certain hormones, such as cortisol and thyroxine, when their specific binding globulins are saturated. Albumin is synthesized in the liver. Low serum levels occur in protein malnutrition, active inflammation and serious hepatic and renal disease. [EU] Aldosterone: (11 beta)-11,21-Dihydroxy-3,20-dioxopregn-4-en-18-al. A hormone secreted by the adrenal cortex that functions in the regulation of electrolyte and water balance by increasing the renal retention of sodium and the excretion of potassium. [NIH] Algorithms: A procedure consisting of a sequence of algebraic formulas and/or logical steps to calculate or determine a given task.

Complement activation occurs by two different sequences, the classic and alternative pathways. The proteins of the classic pathway are termed 'components of complement' and are designated by the symbols C1 through C9. C1 is a calcium-dependent complex of three distinct proteins C1q, C1r and C1s. The proteins of the alternative pathway (collectively referred to as the properdin system) and complement regulatory proteins are known by semisystematic or trivial names. Fragments resulting from proteolytic cleavage of complement proteins are designated with lower-case letter suffixes, e.g., C3a. Inactivated fragments may be designated with the suffix 'i', e.g. C3bi. Activated components or complexes with biological activity are designated by a bar over the symbol e.g. C1 or C4b,2a. The classic pathway is activated by the binding of C1 to classic pathway activators, primarily antigen-antibody complexes containing IgM, IgG1, IgG3; C1q binds to a single IgM molecule or two adjacent IgG molecules. The alternative pathway can be activated by IgA immune complexes and also by nonimmunologic materials including bacterial endotoxins, microbial polysaccharides, and cell walls. Activation of the classic pathway triggers an enzymatic cascade involving C1, C4, C2 and C3; activation of the alternative pathway triggers a cascade involving C3 and factors B, D and P. Both result in the cleavage of C5 and the formation of the membrane attack complex. Complement activation also results in the formation of many biologically active complement fragments that act as anaphylatoxins, opsonins, or chemotactic factors.
