Estrogen-Induced Relaxation In Bovine Coronary Arteries In Vitro: Evidence For A New Mechanism, Jelica D. J. Kalenic, Rolando J. Ramirez, Stanley Einzig, William A. Neal, Hatim A. Omar

Pediatrics Faculty Publications

Numerous studies have shown estrogen to be vasoactive in various circulations. Our objective was to determine the effect of estrogen on isolated bovine coronary arteries and the possible mechanism. Bovine coronary arteries, precontracted with thromboxane mimetic U₄₆₆₁₉ were given doses (0.01-30μM) of 17Β-estradiol in the presence and absence of endothelium and these inhibitors: 10μM indomethacin (cyclooxygenase inhibitor), 10μM methylene blue (inhibits soluble guanylate cyclase), 100μM nitro-L-arginine (inhibits nitric oxide synthesis), 100μM isobutylmethylxanthine (phosphodiesterase inhibitor) and 30μM mifepristone (Ru₃₈₄₈₆ steroid receptor antagonist). Our results indicated that, estrogen, in the highest concentration used (30μM), elicited an acute dose-dependent relaxation of …

Emerging Issues In The Use Of Binding Arbitration To Resolve Disputes Between Individuals And Health Plans, Karl Polzer

National Health Policy Forum

After briefly describing the federal legal framework fostering the growth of binding arbitration, this paper identifies controversies surrounding arbitration as well as arguments supporting and opposing its use. The paper describes the use of arbitration among certain types of collectively bargained employee health plans regulated under the Employee Retirement Income Security Act of 1974 (ERISA), by health maintenance organizations (HMOs) in California, and by a large employer operating a self-insured ERISA health plan. Evidence cited by the California Supreme Court that the largest HMO in California operated its mandatory arbitration program in an unfair way is presented, along with the …

The Use Of Uniaxial And Triaxial Accelerometers To Measure Children's "Free-Play" Physical Activity, Alise E. Ott, Russell R. Pate, Stewart G. Trost, Dianne S. Ward, Ruth P. Saunders

Faculty Publications

In order to effectively measure the physical activity of children, objective monitoring devices must be able to quantify the intermittent and nonlinear movement of free play. The purpose of this study was to investigate the validity of the Computer Science and Applications (CSA) uniaxial accelerometer and the TriTrac-R3D triaxial accelerometer with respect to their ability to measure 8 "free-play" activities of different intensity. The activities ranged from light to very vigorous in intensity and included activities such as throwing and catching, hopscotch, and basketball. Twenty-eight children, ages 9 to 11, wore a CSA and a heart rate monitor while performing …

Lack Of Cd4+ T Cells Does Not Affect Induction Of Cd8+ T-Cell Immunity Against Encephalitozoon Cuniculi Infection, Magali Moretto, Lori Casciotti, Brigit Durell, Imtiaz A. Khan

Dartmouth Scholarship

Cell-mediated immunity has been reported to play an important role in defense against Encephalitozoon cuniculi infection. Previous studies from our laboratory have underlined the importance of cytotoxic CD8⁺ T lymphocytes (CTL) in survival of mice infected with E. cuniculi. In the present study, immune response against E. cuniculi infection in CD4⁺T-cell-deficient mice was evaluated. Similar to resistant wild-type animals, CD4^−/− mice were able to resolve E. cuniculi infection even at a very high challenge dose (5 × 10⁷ spores/mouse). Tissues from infected CD4^−/−mice did not exhibit higher parasite loads in comparison to …

Position Of Γ-Chain Carboxy-Terminal Regions In Fibrinogen/Fibrin Cross-Linking Mixtures, Kevin R. Siebenlist, David A. Meh, Michael W. Mosesson

Biomedical Sciences Faculty Research and Publications

There are conflicting ideas regarding the location of the carboxyl-terminal regions of cross-linked γ-chain dimers in double-stranded fibrin fibrils. Some investigators believe that the chains are always oriented longitudinally along each fibril strand and traverse the contacting ends of abutting fibrin D domains (“DD-long” cross-linking). Other investigations have indicated instead that the chains are situated transversely between adjacent D domains in opposing fibril strands (transverse cross-linking). To distinguish between these two possibilities, the γ dimer composition of factor XIIIa-cross-linked fibrin/fibrinogen complexes that had been formed through noncovalent D/E interactions between fibrinogen D domains and fibrin E domains was examined. Two …

Amino Acid Osmolytes In Regulatory Volume Decrease And Isovolumetric Regulation In Brain Cells: Contribution And Mechanisms, Herminia Pasantes-Morales, Rodrigo Franco, M. Eugenia Torres-Marquez, Karla Hernandez-Fonseca, Arturo Ortega

School of Veterinary and Biomedical Sciences: Faculty Publications

Brain adaptation to hyposmolarity is accomplished by loss of both electrolytes and organic osmolytes, including amino acids, polyalcohols and methylamines. In brain in vivo, the organic osmolytes account for about 35% of the total solute loss. This review focus on the role of amino acids in cell volume regulation, in conditions of sudden hyposmosis, when cells respond by active regulatory volume decrease (RVD) or after gradual exposure to hyposmotic solutions, a condition where cell volume remains unchanged, named isovolumetric regulation (IVR). The amino acid efflux pathway during RVD is passive and is similar in many respects to the volume-activated anion …

Method And Apparatus For Adaptive Filtering By Counting Acoustic Sample Zeroes In Ultrasound Imaging, Gregory R. Bashford, Edward D. Nonnweiler, David D. Becker, David John Muzilla

Biomedical Imaging and Biosignal Analysis Laboratory

An ultrasound imaging system having an adaptive spatial filter the filter coefficients of which, for particular image parameter sample, are determined by counting the number of neighboring image parameter samples having zero or near-zero values. If the number of zero or near-zero values in a data window is greater than a predetermined threshold, the data in the window is passed, not filtered. This filter has two advantages over other spatial filters. First, image parameter data samples having only zero or near-zero neighboring values (i.e., isolated "point noise") are not smeared. Second, boundaries such as the edge of color in a …

Accessory Cell Defect In Unresponsiveness Of Neonates And Aged To Polysaccharide Vaccines., Subbarao Bondada, H Wu, D A Robertson, R L Chelvarajan

Microbiology, Immunology, and Molecular Genetics Faculty Publications

T independent antigens elicit antibody responses in the absence of carrier specific T helper cells but require signals from accessory cells (macrophages and dendritic cells) or specific cytokines. They are further subdivided into TI-1 and TI-2 categories based on the ability of TI-1 but not TI-2 antigens to elicit immune responses from neonates. Most bacterial polysaccharides including the pneumococcal polysaccharide vaccines belong to the TI-2 class. It is hypothesized that defects in accessory cell function play a critical role in the failure of neonates to respond to such TI-2 antigens. Immune responses to these TI-2 stimuli are also reduced in …

Clinical, Pathological And Antigenic Aspects Of Bovine Viral Diarrhea Virus (Bvdv) Type 2 Isolates Identified In Brazil, E. F. Flores, L. H. G. V. Gil, S. A. Botton, R. Weiblen, J. F. Ridpath, L. C. Kreutz, C. Pilati, D. Driemeyer, V. Moojen, A. C. Wendelstein

School of Veterinary and Biomedical Sciences: Faculty Publications

Nucleotide sequencing and phylogenetic analysis of Brazilian bovine viral diarrhea virus (BVDV) field isolates identified four viruses belonging to the genotype 2. Comparison of 5’ UTR sequences from these isolates to those of North American BVDV type 2 revealed genomic variations that correlated with the geographic origins of the isolates. Two of the Brazilian type 2 viruses were isolated from clinical cases of gastroenteric/respiratory disease and two were isolated from healthy bovine fetuses. The clinical cases affected young animals (8- and 18-months-old) and were characterized by diarrhea, respiratory signs, extensive oral and digestive tract erosions, conjunctival and vulvar congestion, occasional …

Relative Volume Of The Cerebellum In Dolphins And Comparison With Anthropoid Primates, L. Marino, James K. Rilling, Shinko K. Lin, Sam H. Ridgway

Veterinary Science and Medicine Collection

According to the ‘developmental constraint hypothesis’ of comparative mammalian neuroanatomy, brain growth follows predictable allometric trends. Therefore, brain structures should scale to the entire brain in the same way across mammals. Evidence for a departure from this pattern for cerebellum volume has recently been reported among the anthropoid primates. One of the mammalian groups that has been neglected in tests of the ‘developmental constraint hypothesis’ is the cetaceans (dolphins, whales, and porpoises). Because many cetaceans possess relative brain sizes in the range of primates comparative tests of the ‘developmental constraint hypothesis’ across these two groups could help to delineate the …

Immunologic Effects Of Gliotoxin In Rats: Mechanisms For Prevention Of Autoimmune Diabetes Mellitus, Honggang Liu, Susan H. Jackman, Henry Driscoll, Bryan Larsen

Biochemistry and Microbiology

Various fungal products, such as gliotoxin (GT), have immunomodulating activity, a fact exploited previously by our group for prevention of autoimmune diabetes mellitus in BB/Wor rats. To understand better the immunologic effects in GT-treated rats, splenocytes from 65-day-old prediabetic diabetes-prone rats were phenotypically characterized after chronic treatment with GT. A parallel study examined the direct effects of GT on splenocyte preparations incubated with the mycotoxin. In vitro treatment of splenocytes with GT revealed relative decreases in CD4+ and increases in CD8+ T-cell subsets, whereas in vivo treatment with GT did not result in detectable alterations in relative CD4+ and CD8+ …

Analysis Of 200 Food Items For Benzo[A]Pyrene And Estimation Of Its Intake Ίη An Epidemiologic Study, Ν. Kazerouni, R. Sinha, Che-Han Hsu, Α. Greenberg, Ν. Rothman

United States Public Health Resources

Animal stιιdies have shown that dietary intake of benzo[α]pyrene (BaP), a polycyclic aromatic hydrocarbon (ΡΑΗ), causes increased levels of tumors at several sites, particιιlarly ίη the upper gastrointestinal tract. However, the role of dietary intake of BaP and cancer ίη humans is not clear. We CIeated a BaP database of selected food products that could be lίnl(ed to Food Frequency Qnestionnaires (FFQs) to estimate BaP intake. BaP levels were measnred for each food line-item (composite samples) which consisted of a variety of foods ίη a FFQ. Composite sample parts were derived from the Second National Health and Nutrition Examination Survey …

Prevalence Of Non-O157:H7 Shiga Toxin-Producing Escherichia Coli In Diarrheal Stool Samples From Nebraska, Paul Fey, R. S. Wickert, M.E. Rupp, T. J. Safranek, S. H. Hinrichs

United States Public Health Resources

We determined the prevalence of Shiga toxin-producing Escherichia coli (STEC) in diarrheal stool samples from Nebraska by three methods: cefixime-tellurite sorbitol MacConkey (CT-SMAC) culture, enterohemorrhagic E. coli (EHEC) enzyme immunoassay, and stx_1,2 polymerase chain reaction (PCR). Fourteen (4.2%) of 335 specimens were positive by at least one method (CT-SMAC culture [6 of 14], EHEC enzyme immunoassay [13 of 14], stx_1,2 PCR [14 of 14]). Six contained serogroup 0157, while non-0157 were as prevalent as 0157 serogroups.

Endocrine Cell Dysplasia (Nesidioblastosis): A Relatively Unrecognized Entity In Pakistan?, Nasim Sabir, Irshad Nabi Soomro, Zafar Nazir, Abdul Jabbar, Sheema Hasan

Section of Paediatric Surgery

Nesidioblastosis is quantitative as well as qualitative abnormality of pancreatic endocrine cells. There is scattering of small endocrine cell clusters arranged haphazardly rather than the peripheral location within the lobule^1,2. Islet contours are irregular, tailing off into parenchyma³. These islets are present in intimate association with ducts forming ductuloinsular complexes¹ We recently encountered a new born baby with signs and symptoms of endocrine cell dysplasia.

The Toxicology Of Aluminum In The Brain: A Review, Robert A. Yokel

Pharmaceutical Sciences Faculty Publications

Aluminum is environmentally ubiquitous, providing human exposure. Usual human exposure is primarily dietary. The potential for significant Al absorption from the nasal cavity and direct distribution into the brain should be further investigated. Decreased renal function increases human risk of Al-induced accumulation and toxicity. Brain Al entry from blood may involve transferrin-receptor mediated endocytosis and a more rapid process transporting small molecular weight Al species. There appears to be Al efflux from the brain, probably as Al citrate. There is prolonged retention of a fraction of Al that enters the brain, suggesting the potential for accumulation with repeated exposure. Al …

Alternatives To Incarceration For Substance Abusing Female Defendants/Offenders In Massachusetts, 1996-1998, Carol Hardy-Fanta, Sylvia Mignon

Publications from the Center for Women in Politics and Public Policy

In July 1997, the Massachusetts State Legislature, recognizing the challenge presented by the problem of substance abuse for women in the criminal justice system, authorized funds to the Department of Public Health’s Bureau of Substance Abuse Services for a study of substance using female offenders to be conducted by the John W. McCormack Institute at the University of Massachusetts Boston. Since March 1998, a group of researchers at the McCormack Institute and the Criminal Justice Center at UMass Boston has gathered and analyzed a wealth of quantitative and qualitative information on women offenders in Massachusetts.

Effects Of Calcium Β-Hmb Supplementation During Training On Markers Of Catabolism, Body Composition, Strength And Sprint Performance, Richard B. Kreider, Maria Pontes Ferreira, Michael Greenwood, M. Wilson, Pamela Grindstaff, Steven Plisk, Jeff Reinardy, Edward Cantler, Anthony L. Amalda

Nutrition and Food Science Faculty Research Publications

Calcium β-hydroxy β-methylbutyrate (HMB) supplementation has been reported to reduce catabolism and promote gains in strength and fat free mass in untrained individuals initiating training. However, the effects of HMB supplementation on strength and body composition alterations during training in athletes is less clear. This study examined the effects of 28-d of calcium HMB supplementation during intense training on markers of catabolism, body composition, strength, and sprint performance. In a double-blind and randomized manner, 28 NCAA division I-A football players were matched-paired and assigned to supplement their diet for 28-d during winter resistance/agility training (~8 hr/wk) with a carbohydrate placebo …
