Transfection Of Il-10 Expression Vectors Into Endothelial Cultures Attenuates Alpha4beta7-Dependent Lymphocyte Adhesion Mediated By Madcam-1., Makoto Sasaki, Paul Jordan, Jeff Houghton, Xianmin Meng, Makoto Itoh, Takashi Joh, J Steven Alexander

Department of Dermatology and Cutaneous Biology Faculty Papers

BACKGROUND: Enhanced expression of MAdCAM-1 (mucosal addressin cell adhesion molecule-1) is associated with the onset and progression of inflammatory bowel disease. The clinical significance of elevated MAdCAM-1 expression is supported by studies showing that immunoneutralization of MAdCAM-1, or its ligands reduce inflammation and mucosal damage in models of colitis. Interleukin-10 (IL-10) is an endogenous anti-inflammatory and immunomodulatory cytokine that has been shown to prevent inflammation and injury in several animal studies, however clinical IL-10 treatment remains insufficient because of difficulties in the route of IL-10 administration and its biological half-life. Here, we examined the ability of introducing an IL-10 expression …

Responsiveness Of Bovine Cumulus-Oocyte-Complexes (Coc) To Porcine And Recombinant Human Fsh, And The Effect Of Coc Quality On Gonadotropin Receptor And Cx43 Marker Gene Mrnas During Maturation In Vitro., Michele D Calder, Anita N Caveney, Lawrence C Smith, Andrew J Watson

Obstetrics & Gynaecology Publications

Substantially less development to the blastocyst stage occurs in vitro than in vivo and this may be due to deficiencies in oocyte competence. Although a large proportion of bovine oocytes undergo spontaneous nuclear maturation, less is known about requirements for proper cytoplasmic maturation. Commonly, supraphysiological concentrations of FSH and LH are added to maturation media to improve cumulus expansion, fertilization and embryonic development. Therefore, various concentrations of porcine FSH (pFSH) and recombinant human FSH (rhFSH) were investigated for their effect on bovine cumulus expansion in vitro. Expression of FSHr, LHr and Cx43 mRNAs was determined in cumulus-oocyte complexes to determine …

Effects Of Tacrolimus On Ischemia-Reperfusion Injury., Shawn D. St Peter, Adyr A. Moss, David C. Mulligan

Manuscripts, Articles, Book Chapters and Other Papers

In addition to efficacious immunosuppression for the benefit of organ transplantation, tacrolimus has diverse actions that result in amelioration of ischemia-reperfusion injury. Knowledge is accumulating rapidly on the mechanisms through which tacrolimus exerts these cytoprotective effects, including alterations in microcirculation, free radical metabolism, calcium-activated pathways, inflammatory cascades, mitochondrial stability, apoptosis, stress-response proteins, and tissue recovery. Within the nucleus, actions mediating the effects of tacrolimus appear to be dominantly influenced by interactions with the transcription factor, nuclear factor-kappaB. Because tacrolimus is a cornerstone agent in immunosuppression regimens throughout the world and knowledge of its cellular mechanisms is evolving, it is important …

Hiv Protease Inhibitors Promote Atherosclerotic Lesion Formation Independent Of Dyslipidemia By Increasing Cd36-Dependent Cholesteryl Ester Accumulation In Macrophages, James Dressman, Jeanie Kincer, Sergey V. Matveev, Ling Guo, Richard N. Greenberg, Theresa Guerin, David Meade, Xiang-An Li, Weifei Zhu, Annette M. Uittenbogaard, Melinda E. Wilson, Eric J. Smart

Physiology Faculty Publications

Protease inhibitors decrease the viral load in HIV patients, however the patients develop hypertriglyceridemia, hypercholesterolemia, and atherosclerosis. It has been assumed that protease inhibitor–dependent increases in atherosclerosis are secondary to the dyslipidemia. Incubation of THP-1 cells or human PBMCs with protease inhibitors caused upregulation of CD36 and the accumulation of cholesteryl esters. The use of CD36-blocking antibodies, a CD36 morpholino, and monocytes isolated from CD36 null mice demonstrated that protease inhibitor–induced increases in cholesteryl esters were dependent on CD36 upregulation. These data led to the hypothesis that protease inhibitors induce foam cell formation and consequently atherosclerosis by upregulating CD36 and …

Tacrolimus As A Liver Flush Solution To Ameliorate The Effects Of Ischemia/Reperfusion Injury Following Liver Transplantation., Shawn D. St Peter, David J. Post, Manuel I. Rodriguez-Davalos, David D. Douglas, Adyr A. Moss, David C. Mulligan

Manuscripts, Articles, Book Chapters and Other Papers

The goal of this report is to evaluate in a prospective randomized fashion the effect of flushing hepatic allografts with tacrolimus before transplantation. A prospective, double-blinded, randomized trial was performed. Twenty patients receiving orthotopic liver transplants from October 2000 to October 2001 were randomized into two groups. Group 1 (active) was administered tacrolimus, 20 ng/mL, plus Plasma-lyte A (Baxter Healthcare Corp, Deerfield, IL) liver flush solution; and group 2 (placebo) was administered only Plasma-lyte A. Ischemia/reperfusion injury was assessed in both groups after transplantation by means of serum laboratory values to assess hepatocellular damage, synthetic function, and ion transport capacity. …

Age, Gender, Biometry, Refractive Error, And The Anterior Chamber Angle Among Alaskan Eskimos, Robert Wojciechowski, Nathan Congdon, William Anninger, Aimee Teo Broman

Dartmouth Scholarship

The prevalence of angle-closure glaucoma (ACG) is greater for Eskimos/Inuit than it is for any other ethnic group in the world. Although it has been suggested that this prevalence may be due to a population tendency toward shallower anterior chamber angles, available evidence for other populations such as Chinese with high rates of ACG has not consistently demonstrated such a tendency.

Semiparametric Receiver Operating Characteristic Analysis To Evaluate Biomarkers For Disease, Tianxi Cai, Margaret S. Pepe

UW Biostatistics Working Paper Series

The receiver operating characteristic (ROC) curve is a popular method for characterizing the accuracy of diagnostic tests when test results are not binary. Various methodologies for estimating and comparing ROC curves have been developed. One approach, due to Pepe, uses a parametric regression model with the baseline function specified up to a finite-dimensional parameter. In this article we extend the regression models by allowing arbitrary nonparametric baseline functions. We also provide asymptotic distribution theory and procedures for making statistical inference. We illustrate our approach with dataset from a prostate cancer biomarker study. Simulation studies suggest that the extra flexibility inherent …

Vinpocetine For Cognitive Impairment And Dementia, Peter J. Whitehouse

Faculty Scholarship

Background: Vinpocetine is a synthetic ethyl ester of apovincamine, a vinca alkaloid obtained from the leaves of the Lesser Periwinkle (Vinca minor) and discovered in the late 1960s. Although used in human treatment for over twenty years, it has not been approved by any regulatory body for the treatment of cognitive impairment. Basic sciences studies have been used to claim a variety of potentially important effects in the brain. However, despite these many proposed mechanisms and targets, the relevance of this basic science to clinical studies is unclear. Objectives: To assess the efficacy and safety of vinpocetine in the treatment …

Regulation Of Human Col9a1 Gene Expression. Activation Of The Proximal Promoter Region By Sox9., Ping Zhang, Sergio A. Jimenez, David G Stokes

Department of Medicine Faculty Papers

The COL9A1 gene contains two promoter regions, one driving expression of a long alpha1(IX) chain in cartilage (upstream) and one driving expression of a shorter chain in the cornea and vitreous (downstream). To determine how the chondrocyte-specific expression of the COL9A1 gene is regulated, we have begun to characterize the upstream chondrocyte-specific promoter region of the human COL9A1 gene. Transient-transfection analyses performed in rat chondrosarcoma (RCS) cells, human chondrosarcoma (HTB) cells, and NIH/3T3 cells showed that the COL9A1 promoter was active in RCS cells but not HTB or NIH/3T3 cells. Inclusion of the first intron had no effect on promoter …

Synergistic Interactions Of Chlorambucil, Dha, And Trail In Jurkat And H460 Human Cancer Cells, Jennifer Ellen Bush-O'Donnell

Theses, Dissertations and Capstones

Traditional chemotherapeutic drugs are prone to toxicity and may result in secondary cancers. In recent years much attention has been garnered by alternate methods of cancer treatment with fewer side effects, including immunotherapy and administration of ω-3 fatty acids, both of which have been shown to cause apoptosis in cancer cells. Docosahexaenoic acid (DHA), a fatty acid, is a normal component of cell membranes and is safe for systemic administration. The cytokine TRAIL (tumor necrosis factorrelated apoptosis-inducing ligand) is able to induce apoptosis in cancer cells while sparing normal tissue. In this study, the alkylating agent chlorambucil (CLB) was combined …

Utilization Of Emergency Policies And Procedures By Division I-A And Division I-Aa Intercollegiate Athletic Programs, Brandy A. Petty

Lupus Anticoagulunt Associated With Transient Severe Factor X Deficiency: A Report Of Two Patients Presenting With Major Bleeding Complications, Aneel A. Ashrani, Agnes Aysola, Hani Al-Khatib Md, William L. Nichols

Articles

Abstract

Acquired factor X (FX) deficiency is rare, but has been reported in diverse disease states, including systemic amyloidosis and respiratory infections. FX deficiency associated with lupus anticoagulant (LA) and a bleeding diathesis has not been previously reported. We report two patients both of whom presented with a severe bleeding diathesis after a preceding respiratory infection due to isolated FX deficiency associated with a LA. The FX deficiency and LA were transient. We conclude that patients with LA may rarely present with severe acquired FX deficiency. This may be another mechanism whereby patients with antiphospholipid antibodies present with bleeding complications.

Clinical Issues Surrounding Once-Daily Aminoglycoside Dosing In Children, Chad A. Knoderer, Julie A. Everett, William F. Buss

Scholarship and Professional Work – COPHS

Aminoglycoside antibiotics are first-line treatment for many infectious diseases in the pediatric population and are effective in adults. The traditional dosing interval in children is every 8–12 hours. Studies in adults reported equivalent efficacy and equal or less toxicity with once-daily regimens. Despite many studies in the adult population, this approach has yet to become standard practice in most pediatric hospitals. Reasons for lack of acceptance of this strategy in children include rapid aminoglycoside clearance, unknown duration of postantibiotic effect, safety concerns, and limited clinical and efficacy data.

Susceptibility Scoring In Family-Based Association Testing, Laila M. Poisson, Benjamin A. Rybicki, Steven W. Coon, Jill S. Barnholtz-Sloan, Gary A. Chase

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

Family-based association testing is an important part of genetic epidemiology. Tests are available to include multiple siblings, unaffected offspring, and to adjust for environmental covariates. We explore a susceptibility residual method of adjustment for covariates.

Results

Through simulation, we show that environmental adjustments that down-weight persons who are "destined" to be affected decrease the power to detect genetic association. We used the residual adjusted method on the Framingham Heart Study offspring data, provided for Genetic Analysis Workshop 13, and got mixed results.

Conclusion

When the genetic effect and environmental effects are independent, a susceptibility residual method of adjustment …

Analysis Of Gene × Environment Interactions In Sibships Using Mixed Models, Jill S. Barnholtz-Sloan, Laila M. Poisson, Steven W. Coon, Gary A. Chase, Benjamin A. Rybicki

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

Gene × environment models are widely used to assess genetic and environmental risks and their association with a phenotype of interest for many complex diseases. Mixed generalized linear models were used to assess gene × environment interactions with respect to systolic blood pressure on sibships adjusting for repeated measures and hierarchical nesting structures. A data set containing 410 sibships from the Framingham Heart Study offspring cohort (part of the Genetic Analysis Workshop 13 data) was used for all analyses. Three mixed gene × environment models, all adjusting for repeated measurement and varying levels of nesting, were compared for …
