497. MOLECULAR MODELING OF ASPARAGINE SYNTHETASE. Robert Humkey, Yun Ding, and Nigel G.J. Richards, Department of Chemistry, University of Florida, Box 117200, Gainesville, FL 32611-7200, humkey qtp.ufl The enzyme asparagine synthetase AS ; catalyzes the biochemical conversion of aspartate to asparagine. A direct correlation between the development of drug-resistance in leukemia and the over-expression of AS has recently been observed. This connection has led to the belief that an inhibitor of AS would be able to reverse the effects of drug resistance in leukemia cells. A molecular model of E. coli asparagine synthetase-B AS-B ; will be presented as the first complete structural insight into the critical active sites of this enzyme. The model is being used to examine the different effects of the binding of structurally analogous inhibitors and non-inhibitors on AS-B, as well as identifying the specific active site interactions that can be used to facilitate inhibitor binding. 498. NOVEL INHIBITORS OF CARBONYL REDUCTASE. Berea Williams, Corianton L. Larson, Andrew Slupe, Kristofor Olson, Sanela Begic, Laura Lee, and Henry A. Charlier Jr., Department of Chemistry, Boise State University, 1910 University Drive, Boise, ID 83725-1520, willbere2000 yahoo Anthracyclines are effective antineoplasticagents, but are known to cause a potentially lethal chronic cardiomyopathy, which severely limits their use. Anthracycline cardiotoxicity has been linked to the formation of a metabolite catalyzed by carbonyl reductase CR ; . Since the metabolite does not possess the antineoplastic properties of its parent anthracycline, the action of CR may also contribute to drug resistance. In an effort to prevent the CR derived formation of the cardiotoxic metabolite, CR inhibitor candidates were tested. Of the compounds that were tested, two were found to be noncompetitive inhibitors against both coenzyme and carbonyl substrates, with KI values in the low micromolar range. The inhibition patterns suggest that the inhibitors bind to multiple enzyme forms. Intrinsic protein fluorescence quenching studies demonstrated that the inhibitors bind to at least the free enzyme and to an enzyme product binary complex with Kd values similar to the KI values.

Michelle Piel, Kristina Thornburg, Christopher Higgins, Francis Charles Mayville Jr., and Peter Leonard, Natural Science Department, DeSales University, 2755 Station Avenue, Center Valley, PA 18034, Fax: 610-282-0525, fcm0 desales , fcm0 desales In this study, we are synthesizing new polyamine analogs using 1, 4-diaminobutane putrescine ; as the template. The new polyamine derivatives will contain two, three, or four carbon primers at the each amino end of the putrescine. It has been previously determined that the polyamine systems can bind to the minor grooves of DNA molecules and inhibit cell growth. In other previous work, the inhibition of cell growth has been studied using several synthesized polyamine derivatives, and it was found that these artificial systems had more inhibition ability then natural polyamines. In our study, the new polyamine systems will be compared with current polyamine analogs to determine their efficacy for inhibition of cell growth in MCF-7 breast cancer cell lines. The methods of analysis will include HPLC analysis of nuclear DNA and gross cell counting. The clinical spectrum of diverticular disease DD ; varies from an asymptomatic condition, incidentally found when the colon is investigated for any reason, to symptomatic disease with potentially lethal complications. Diverticular disease is more common in the industrialised world compared with developing countries Painter and Burkitt, 1971 ; . Its incidence increases with age. Health expenses are significant and DD was recently ranked the fifth most costly digestive disease in the USA Sandler et al., 2002 ; . The rate of hospital admissions due to DD increased 23 % in Sweden between 1992 and 2002 Centre for Epidemiology, 2002 ; . There are no generally accepted diagnostic criteria for DD. Usually, examination of the colon supports the clinical diagnosis and is performed either with a barium enema BE ; or with colonoscopy CC ; . Figure 1 a and b ; Figure 1.

Sleep apnea in children can lead to brain cell damage and lowered intelligence, new research suggests. Brain imaging showed that children with untreated, severe sleep apnea show evidence of injury in the regions of the brain responsible for learning, memory, and complex thought. These children also had lower IQ scores and they scored lower on standardized learning tests than children without the sleep disorder. Further research is being done to determine if treatment will reverse any brain injury because sleep apnea is very treatable in children and if it does cause permanent impairment in [brain] function that makes early treatment all the more important.

Abstract--Ca2 -regulated gene transcription is a critical component of arterial responses to injury, hypertension, and tumor-stimulated angiogenesis. The Ca2 cAMP response element binding protein CREB ; , a transcription factor that regulates expression of many genes, is activated by Ca2 -induced phosphorylation. Multiple Ca2 entry pathways may contribute to CREB activation in vascular smooth muscle including voltage-dependent Ca2 channels and store-operated Ca2 entry SOCE ; . To investigate a role for SOCE in CREB activation, we measured CREB phosphorylation using immunofluorescence, intracellular Ca2 levels using a fluorescence resonance energy transfer FRET ; based Cameleon indicator, and c-fos transcription using RT-PCR. In this study, we report that SOCE activates CREB in both cultured smooth muscle cells and intact arteries. Depletion of intracellular Ca2 stores with thapsigargin increased nuclear phospho-CREB levels, intracellular Ca2 concentration, and transcription of c-fos. These effects were abolished by inhibiting SOCE through lowering extracellular Ca2 concentration or by application of 2-aminoethoxydiphenylborate and Ni2 . Inhibition of Ca2 influx through voltage-dependent Ca2 channels using nimodipine partially blocked intact artery responses, but was without effect in cultured smooth muscle cells. Our findings indicate that Ca2 entry through store-operated Ca2 channels leads to CREB activation, suggesting that SOCE contributes to the regulation of gene expression in vascular smooth muscle.

We give first thought to patients and their families, and to increasing the benefits health care provides. Such as improved productivity for employers. Another significant benefit for an MCO is the ability to identify significant adverse events with new therapies. For example, in 2004 a new biologic, natalizumab Tysabri ; , was approved for treating RRMS. Use of this agent skyrocketed from November 2004 to February 2005 until the agent was removed from the market because of significant adverse effects including several deaths ; .51 Intense tracking of adverse effects through a disease management program will identify significant and potentially life-threatening events early. A disease management program will allow the needed data collection to manage inappropriate use of a new or unproven medication and nateglinide. For purposes of evaluating this method, nimodipine is incubated with rat, dog, monkey, and human hepatic microsomes over a 60-min period.

ABSTRACT #181 INTRACELLULAR ACCUMULATION OF THE ACTIVE CYTOTOXIC METABOLITE OF GEMCITABINE IN DOGS. Martin-Jimenez, T., Freise, K.J. College of Veterinary Medicine, University of Illinois, Urbana, IL. Gemcitabine dFdC ; is a relatively new chemotherapeutic agent in humans and its use in canine oncology is being actively explored with mixed responses. Results in humans and other species indicate improved therapeutic outcome and increased intracellular accumulation of the active cytotoxic metabolite, gemcitabine triphosphate dFdCTP ; when doses are given over a long infusion relative to a short bolus dose. Additionally, it appears that plasma and extracellular dFdC concentrations exceeding a certain threshold actually cause a decrease in intracellular dFdCTP concentrations. It is unknown in dogs if dFdC infusions give increased intracellular dFdCTP concentrations and if inhibition of dFdCTP accumulation occurs with increasing dFdC levels. Without this information, it is difficult to design and adjust doses of dFdC in clinical oncology. Five intact female dogs in an incomplete block crossover design were administered 3, 10, and 30 mg kg dFdC as an IV bolus in phase I. In phase II using the same design the dogs were administered 10, 30, and 60 mg kg doses as an IV bolus with a 30 minute CRI so that plasma dFdC concentrations remained constant the entire infusion period. Serial blood samples were collected after each dose, the plasma fraction being analyzed for dFdC by HPLC and the peripheral blood mononuclear cells PBMCs ; being isolated. The PBMCs were counted via flow cytometry and analyzed for intracellular dFdCTP by LC MS. The resulting dFdCTP concentrations, normalized by cell number, were compared for the different doses and administration routes. Additionally, an in vitro study was conducted examining the intracellular accumulation of dFdCTP in canine melanoma cells administered 5 doses for either 2 or 4 hours. In phase I the 10 mg kg dose of dFdC had a higher PBMC intracellular accumulation of dFdCTP in selected animals than the 30 mg kg dose. In phase II results were mixed, with some animals showing the 10 mg kg dose had a higher dFdCTP accumulation than the 60 mg kg dose while other animals saw a slight increase in PBMC intracellular accumulation with increasing dose, though not proportional to the dose. The in vitro study showed that dose p 0.0001 ; , time p 0.0001 ; , and the time by dose interaction p 0.0485 ; all had significant effects on intracellular dFdCTP accumulation and a simple Emax model best fit the data. Increased dFdC exposure did not cause a corresponding increase in intracellular dFdCTP accumulation when the higher exposure occurred by administration of a high concentration over 2 hours compared to a lower concentration administered over 4 hours. The phase I in vivo results suggest an inhibition model best describes the intracellular metabolism of dFdC to dFdCTP, while in phase II a saturation model appeared most appropriate. A saturation model clearly best fit the data for the in vitro experiment. Based on these results and clinical reports our recommendation for the most appropriate dFdC dose to maximize therapeutic potential is 10 mg kg administered IV over 30 minutes or longer. Enterococci can be found in soil, food and water, and they make up a significant portion of the normal intestinal flora of humans 105-107 g of stool ; and animals Kayser, 2003 ; . Enterococcus faecium and E. faecalis are residents of the normal intestinal flora of humans and animals. They are usually Gram-positive oval or spherical cells arranged in pairs or chains. They are aerobic or facultative anaerobes. Enterococcus spp, belonging to the normal intestinal flora have been documented to produce bacteriocins against Listeria spp. Sullivan and Nord, 2002 ; . They have been documented to reduce antibiotic-associated diarrhoea in humans Tuohy et al., 2003 ; and gastroenteritis in adults Holzapfel and Schillinger, 2002 ; . Enterococci are increasingly involved in nosocomial infections and readily transfer antibiotic resistance Sullivan and Nord, 2002 ; . Most pathogenic isolates in humans are E. faecalis, which account for 80 - 90 % of clinical isolates. E. faecium represented 5 10 % of clinical isolates Kayser, 2003 ; . Enterococcus faecium can transmit vancomycin resistance Weese, 2002 ; . Many clinical strains of E. faecalis produce a cytolysin haemolysin ; that causes tissue damage Kayser, 2003 ; . Many of the clinical isolates also possess aggregation substances on the surface and an extracellular surface protein. These contribute to their ability to adhere to eukaryotic cells. E. faecium has been shown to favour the adhesion and colonization of Clostridium jejuni in the dog's intestine Rinkinen et al., 2003 ; . Even though not all strains of enterococci are considered a health risk, the use of enterococci as probiotics is controversial. Kayser 2003 ; proposes a two stage process in the establishment of pathogenic enterococci: firstly colonisation of the gastrointestinal tract by enterococcal strains possessing virulence traits, followed by a subsequent tissue invasion associated with elimination or disturbance of the normal microbial flora particularly in immunocompromised humans Kayser, 2003 ; . Pathogenic strains of Enterococcus spp. should be avoided when selecting stains for probiotics and nicotine. 1. Rudis MI, Jacobi J, Hassan E, Dasta JF. Managing anemia in the critically ill patient. Pharmacotherapy 2004; 24: 22947. This is an excellent review on the topic of anemia of critical illness for ICU clinicians, particularly pharmacists. Although the epidemiology and pathophysiology of anemia of critical illness are discussed briefly, the clinical consequences of anemia of critical illness are discussed in greater detail. The most useful part of this review, particularly for pharmacists, is the detailed review of the pharmacotherapy, including an in-depth review of the literature supporting the use of iron therapy, blood products, and erythropoietic agents. The authors also discuss the investigational "blood substitutes" currently in development. Lastly, the review provides some perspective in terms of pharmacoeconomic considerations in the treatment of anemia of critical illness. Scharte M, Fink MP. Red blood cell physiology in critical illness. Crit Care Med 2003; 31 suppl ; : S6517. This review provides a comprehensive look at the pathophysiological aspects of anemia of critical illness. Although some of these concepts are discussed in the review by Rudis et al. Reference 1 ; , the multifaceted physiology of red blood cells is described in much greater detail. The discussions on erythropoietin expression, iron metabolism, and the role of inflammatory mediators are helpful in understanding both the physiology and treatment of anemia of critical illness. Other factors contributing to the development of anemia in this setting are discussed as well, including hemolysis and phlebotomy in critically ill patients. McLellan SA, McClelland DBL, Walsh TS. Anaemia and red blood cell transfusion in the critically ill patient. Blood Rev 2003; 17: 195208. This review article nicely supplements the reviews listed above. Pathophysiology is briefly summarized, followed by in-depth discussion on the risks of anemia in these patients and appropriate transfusion triggers, with an emphasis on special populations to consider. The article ends with a brief section on the potential role of recombinant erythropoietin in this setting. Also helpful are the many tables provided that nicely summarize causes of anemia of critical illness, the impact of anemia on oxygen-carrying capacity, critical hemoglobin triggers, physiological parameters to assess tissue oxygenation in critically ill patients, and issues related to red blood cell storage. Finally, the article ends with two bulleted summary boxes, one discussing practice points or clinical pearls and the other suggesting future research endeavors to better understand how to manage critically ill patients with anemia, for instance, fibromyalgia.
