Cutting Rate Effect On Temperature During Cortical Bone Sawing, Hamid Khalili Parsa, Ger Reilly, Brendan Mccormack

Conference Papers

When bone is cut the occurrence of thermal damage to the bone is of major concern to the surgeon. If the temperature exceeds 44°C for longer than 1 min, bone repair is impaired (Eriksson et al, 1984) and necrosis may occur. Repeated use of cutting blades may reduce the cutting efficiency (Wevers et al, 1987; Toksvig-Larsen et al, 1992). Wevers et al also found that there is a greater force required to cut cortical bone using a blunt saw compared to new one.

Androgen Excess Disorders In Women: The Severe Insulin-Resistant Hyperandrogenic Syndrome, Hair-An, Kristin M. Rager, Hatim A. Omar

Pediatrics Faculty Publications

HAIR-AN syndrome (hyperandrogenism, insulin resistance, acanthosis nigricans) is a subset of the polycystic ovary syndrome, where the patients demonstrate severe insulin resistance. It is theorized that both genetic and environmental factors, such as obesity, give rise to the development of HAIR-AN. Diagnosis is primarily clinical, with laboratory values lending further support. Treatment is aimed at decreasing insulin resistance, regulating ovulation, and decreasing acne, acanthosis nigricans, and hirsutism.

Measuring Sustained Attention After Traumatic Brain Injury: Differences In Key Findings From The Sustained Attention To Response Task (Sart), John Whyte, Patricia Grieb-Neff, Christopher Gantz, Marcia Polansky

Department of Rehabilitation Medicine Faculty Papers

Clinical reports after traumatic brain injury (TBI) suggest frequent difficulties with sustained attention, but their objective measurement has proved difficult. In 1997, Robertson and colleagues reported on a new sustained attention assessment tool, the sustained attention to response task (SART). Individuals with TBI were reported to produce more errors of commission on the SART than control participants, and both groups showed a relationship between SART errors and everyday lapses of attention as measured by the cognitive failures questionnaire (CFQ). Although few direct replications of these findings have been reported, the SART has been used widely as a measure of sustained …

Na+/K+ -Atpase Regulates Tight Junction Formation And Function During Mouse Preimplantation Development., Michelle I Violette, Pavneesh Madan, Andrew J Watson

Obstetrics & Gynaecology Publications

Research applied to the early embryo is required to effectively treat human infertility and to understand the primary mechanisms controlling development to the blastocyst stage. The present study investigated whether the Na(+)/K(+)-ATPase regulates tight junction formation and function during blastocyst formation. To investigate this hypothesis, three experimental series were conducted. The first experiments defined the optimal dose and treatment time intervals for ouabain (a potent and specific inhibitor of the Na(+)/K(+)-ATPase) treatment. The results demonstrated that mouse embryos maintained a normal development to the blastocyst stage following a 6-h ouabain treatment. The second experiments investigated the effects of ouabain treatment …

Physiological Effects On Demography: A Long‐Term Experimental Study Of Testosterone’S Effects On Fitness, W. Reed, M. Clark, P. Parker, S. Raouf, N. Arguedas, D. Monk, E. Snajdr, V. Nolan, E. Ketterson

Biology Department Faculty Works

Understanding physiological and behavioral mechanisms underlying the diversity of observed life‐history strategies is challenging because of difficulties in obtaining long‐term measures of fitness and in relating fitness to these mechanisms. We evaluated effects of experimentally elevated testosterone on male fitness in a population of dark‐eyed juncos studied over nine breeding seasons using a demographic modeling approach. Elevated levels of testosterone decreased survival rates but increased success of producing extra‐pair offspring. Higher overall fitness for testosterone‐treated males was unexpected and led us to consider indirect effects of testosterone on offspring and females. Nest success was similar for testosterone‐treated and control males, …

Lactate Versus Non-Lactate Metabolic Acidosis: A Retrospective Outcome Evaluation Of Critically Ill Patients, Kyle J. Gunnerson, Melissa Saul, Shui He, John A. Kellum

Anesthesiology Publications

Introduction

Acid–base abnormalities are common in the intensive care unit (ICU). Differences in outcome exist between respiratory and metabolic acidosis in similar pH ranges. Some forms of metabolic acidosis (for example, lactate) seem to have worse outcomes than others (for example, chloride). The relative incidence of each type of disorder is unknown. We therefore designed this study to determine the nature and clinical significance of metabolic acidosis in critically ill patients.

Methods

An observational, cohort study of critically ill patients was performed in a tertiary care hospital. Critically ill patients were selected on the clinical suspicion of the presence of …

This study was a prospective, randomized and controlled trial. Patients were subjected to normothermic CPB (35 to 36°C) and were observed until discharge from the intensive care unit (ICU). Outcome measures were calculated whole body oxygen delivery, oxygen consumption and clinical outcome. A …

The Reckless Pursuit Of Dominion: A Situational Analysis Of The Nba And Diminishing Player Autonomy, Michael Mccann

Law Faculty Scholarship

This Article examines required genetic testing of NBA players from a situational vantage point, integrating socio-psychological, legal, and ethical analyses. The core argument may be expressed as follows: required genetic testing of NBA players appears consistent with a broader and largely deleterious agenda by the NBA to control players. Since implementation of the rookie wage scale in 1995 through the recent imposition of a paternalistic player dress code, the NBA has increasingly usurped player autonomy. The NBA's capacity to do so largely rests in its adroit manipulation of the situational influences that influence fans and media. For instance, because of …

We discuss common definitions of BI, applications within common models of translation research, effects of BI on a range of health behaviors and across various populations, current and potential mechanisms, and uses for dissemination to practice. A number of advantages of BI suggest they are well suited for translating behavioral research. In addition, findings from 13 systematic reviews of BI effects show their potential versatility. Basic research on motivation, decision making, and persuasion may be …

Differences In Mnemonic Processing By Neurons In The Human Hippocampus And Parahippocampal Regions, Indre Viskontas, B. J. Knowlton, P. N. Steinmetz, I. Fried

Psychology

Different structures within the medial-temporal lobe likely make distinct contributions to declarative memory. In particular, several current psychological and computational models of memory predict that the hippocampus and parahippocampal regions play different roles in the formation and retrieval of declarative memories [e.g., Norman, K. A., & O'Reilly, R. C. Modeling hippocampal and neocortical contributions to recognition memory: A complementary-learning systems approach. Psychological Review, 110, 611-646, 2003]. Here, we examined the neuronal firing patterns in these two regions during recognition memory. Recording directly from neurons in humans, we find that cells in both regions respond to novel stimuli with an increase …

Cyclooxygenase-2 Expression In Hamster And Human Pancreatic Neoplasia, Pamela L. Crowell, C. Max Schmidt, Michele T. Yip-Schneider, Jesse J. Savage, Dean A. Hertzler Ii, William O. Cummings

Scholarship and Professional Work – COPHS

Cyclooxygenase-2 (COX-2) has been implicated in the development of gastrointestinal malignancies. The aim of the present study was to determine COX-2 expression/activity throughout stages of experimental and human pancreatic neoplasia. COX-2 immunohistochemistry was performed in pancreata of hamsters subjected to the carcinogen N-nitrosobis-(2-oxopropyl)amine (BOP) and in human pancreatic tumors. COX-2 activity was determined by prostaglandin E₂ assay in tumor versus matched normal pancreatic tissues. The activity of the COX inhibitor sulindac was tested in the PC-1 hamster pancreatic cancer model. COX-2 expression was elevated in all pancreatic intraepithelial neoplasias (PanINs) and adenocarcinomas. In BOP-treated hamsters, there were significant …

Cyclosporin Versus Tacrolimus For Liver Transplanted Patients, Elizabeth Haddad, Vivian Mcalister, Elizabeth Renouf, Richard Malthaner, Mette S. Kjaer, Lise Lotte Gluud

Surgery Publications

A systematic review of randomized clinical trials (RCT) was undertaken to evaluate the beneficial and harmful effects of immunosuppression with cyclosporin versus tacrolimus for liver transplanted patients. MEDLINE, EMBASE, Cochrane Central and Hepato-Biliary Group Controlled Trials Registers were searched. Using fixed and random effects model, relative risk (RR), values <1 favoring>tacrolimus, with 95% confidence intervals (CI) were calculated. Of 717 potentially relevant references, 16 RCTs were eligible for inclusion. Mortality and graft loss at 1 year were significantly reduced in tacrolimus-treated recipients (Death: RR 0.85, 95% CI 0.73-0.99; graft loss: RR 0.73, 95% CI 0.61-0.86). Tacrolimus reduced the number of recipients …

Body Contouring After Massive Weight Loss, Edited By A. Aly, Vivian Mcalister

Data and Test Instruments

Nowhere is the failure of the health care system, as currently managed, more evident than in the surgical care of obesity. A marked contrast has emerged between surgery in the United States and Canada for these patients. It is not clear whether the reluctance to supply surgical services in Canada is due to a bias in favour of “more deserving” patients or whether the considerably higher rate of obesity surgery in the US is due to the excesses of private enterprise. Governments have acknowledged that an element of the former proposition is true by referring obese patients to centres in …

Cyclin D1 And P16 Expression In Recurrent Nasopharyngeal Carcinoma, Ho-Sheng Lin, Gerald J. Berry, Zijie Sun, Willard E. Fee Jr

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

Cyclin D1 and p16 are involved in the regulation of G1 checkpoint and may play an important role in the tumorigenesis of nasopharyngeal carcinoma (NPC). Previous studies have examined the level of expression of cyclin D1 and p16 in primary untreated NPC but no such information is available for recurrent NPC. We set out in this study to examine the expression level of cyclin D1 and p16 in recurrent NPC that have failed previous treatment with radiation +/- chemotherapy.

Patients and methods

A total of 42 patients underwent salvage nasopharyngectomy from 1984 to 2001 for recurrent NPC after …

Effect Of Changes In Contractility On The Index Of Myocardial Performance In The Dysfunctional Left Ventricle, Steven J. Lavine

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

The index of myocardial performance has prognostic power in patients with cardiomyopathy and following myocardial infarction. As the index of myocardial performance has been shown to be preload and afterload dependent, the effect of altering contractility on IMP and its components with left ventricular dysfunction has been incompletely delineated.

Methods

Chronic left ventricular dysfunction was induced in 10 canines using coronary microsphere embolization. Each dog was instrumented and imaged with 2D echo and Doppler. At the same atrially paced rate, contractility was increased with a dobutamine infusion and then following 4 weeks of oral digoxin.

Results

With chronic …

Genistein Inhibits Radiation-Induced Activation Of Nf-Κb In Prostate Cancer Cells Promoting Apoptosis And G2/M Cell Cycle Arrest, Julian J. Raffoul, Yu Wang, Omer Kucuk, Jeffrey D. Forman, Fazlul H. Sarkar, Gilda G. Hillman

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

New cancer therapeutic strategies must be investigated that enhance prostate cancer treatment while minimizing associated toxicities. We have previously shown that genistein, the major isoflavone found in soy, enhanced prostate cancer radiotherapy in vitro and in vivo. In this study, we investigated the cellular and molecular interaction between genistein and radiation using PC-3 human prostate cancer cells.

Methods

Tumor cell survival and progression was determined by clonogenic analysis, flow cytometry, EMSA analysis of NF-κB, and western blot analysis of cyclin B1, p21^WAF1/Cip1, and cleaved PARP protein.

Results

Genistein combined with radiation caused greater inhibition in PC-3 …

Arterial Blood Pressure Monitoring In Overweight Critically Ill Patients: Invasive Or Noninvasive?, Ali Araghi, Joseph J. Bander, Jorge A. Guzman

Wayne State University Associated BioMed Central Scholarship

Abstract

Introduction

Blood pressure measurements frequently guide management in critical care. Direct readings, commonly from a major artery, are considered to be the gold standard. Because arterial cannulation is associated with risks, alternative noninvasive blood pressure (NIBP) measurements are routinely used. However, the accuracy of NIBP determinations in overweight patients in the outpatient setting is variable, and little is known about critically ill patients. This prospective, observational study was performed to compare direct intra-arterial blood pressure (IABP) with NIBP measurements obtained using auscultatory and oscillometric methods in overweight patients admitted to our medical intensive care unit.

Method

Adult critically ill …

Characterization Of Pancreatic Lesions From Mt-Tgfα, Ela-Myc And Mt-Tgfα/Ela-Myc Single And Double Transgenic Mice, Dezhong Liao, Yong Wang, Jiusheng Wu, Nazmi Adsay, David Grignon, Fayyaz Khanani, Fazlul H. Sarkar

Wayne State University Associated BioMed Central Scholarship

Abstract

In order to identify good animal models for investigating therapeutic and preventive strategies for pancreatic cancer, we analyzed pancreatic lesions from several transgenic models and made a series of novel findings. Female MT-tgfα mice of the MT100 line developed pancreatic proliferation, acinar-ductal metaplasia, multilocular cystic neoplasms, ductal adenocarcinomas and prominent fibrosis, while the lesions in males were less severe. MT-tgfα-ES transgenic lines of both sexes developed slowly progressing lesions that were similar to what was seen in MT100 males. In both MT100 and MT-tgfα-ES lines, TGFα transgene was expressed mainly in proliferating ductal cells. Ela-myc transgenic mice with a …
