Human ovarian cancer is diagnosed in the late, metastatic stages but the underlying mechanisms remain poorly understood. We report a surprising functional link between CD151-α3β1 integrin complexes and the malignancy of serous-type ovarian cancer. Analyses of clinical specimens indicate that CD151 expression is significantly reduced or diminished in 90% of metastatic lesions, while it remains detectable in 58% of primary tumors. These observations suggest a putative tumor-suppressing role of CD151 in ovarian cancer. Indeed, our analyses show that knocking down CD151 or α3 integrin enhances tumor cell proliferation, growth and ascites production in nude mice. These changes are accompanied by …

Comparison: Perception And Knowledge Of Protein Consumption In Female Athletes For Post Weight Lifting Recovery, Samantha Jane Lofton

Senior Honors Projects, 2010-2019

A study was conducted on James Madison University’s campus to assess the knowledge, beliefs, perceptions and habits of protein consumption post resistance training in female student athletes. Sixty-two female athletes who regularly partake in resistance training filled out a recovery-cue questionnaire containing 10 statements/questions on the subject of protein consumption. The data was analyzed using IBM SPSS, Version 21.0 and Microsoft Office Excel. Eight percent of respondents stated they are aware of how much protein they should be consuming post workout, and 21% feel what they consume post workout is an adequate amount of protein for muscle recovery. Forty-six percent …

Repeated Transradial Catheterization: Feasibility, Efficacy, And Safety, Marinos A Charalambous, Savvas S Constantinides, Michael A Talias, Elpidoforos S Soteriades, Christos P Christou

The Texas Heart Institute Journal

Transradial access is an alternative to the transfemoral approach in coronary interventions. It results in less access-site bleeding, shorter hospital stays, lower costs, and less pain for the patient. However, some authors have suggested that the transradial approach might lead to radial artery occlusion, which precludes repeated same-artery catheterizations. Using data from our center, we evaluated the feasibility, safety, and efficacy of repeated transradial catheterization.

We reviewed the 3,006 transradial catheterizations performed at our center from 2006 through 2009. Patients who had undergone at least one repeated transradial catheterization were identified, their cases monitored through 2012, and their baseline characteristics …

Percutaneous Repair Of Post-Myocardial Infarction Ventricular Septal Defect: Current Approaches And Future Perspectives, Maria D Baldasare, Mark Polyakov, Glenn W Laub, Joseph T Costic, Daniel J Mccormick, Sheldon Goldberg

The Texas Heart Institute Journal

Post-myocardial infarction ventricular septal defect is a devastating complication of ST-elevation myocardial infarction. Although surgical intervention is considered the gold standard for treatment, it carries high morbidity and mortality rates. We present 2 cases that illustrate the application of percutaneous closure of a post-myocardial infarction ventricular septal defect: the first in a patient who had undergone prior surgical closure and then developed a new shunt, and the second as a bridge to definitive surgery in a critically ill patient.

Wordless Intervention For Epilepsy In Learning Disabilities (Wield): Study Protocol For A Randomized Controlled Feasibility Trial, Marie-Anne Durand, Bob Gates, Georgina Parkes, Asif Zia

Dartmouth Scholarship

Epilepsy is the most common neurological problem that affects people with learning disabilities. The high seizure frequency, resistance to treatments, associated skills deficit and co-morbidities make the management of epilepsy particularly challenging for people with learning disabilities. The Books Beyond Words booklet for epilepsy uses images to help people with learning disabilities manage their condition and improve quality of life. Our aim is to conduct a randomized controlled feasibility trial exploring key methodological, design and acceptability issues, in order to subsequently undertake a large-scale randomized controlled trial of the Books Beyond Words booklet for epilepsy.

Entomology Faculty Publications

A previous study documented a glycine to glutamic acid mutation (G4946E) in ryanodine receptor (RyR) was highly correlated to diamide insecticide resistance in field populations of Plutella xylostella (Lepidoptera: Plutellidae). In this study, a field population collected in Yunnan province, China, exhibited a 2128-fold resistance to chlorantraniliprole. Sequence comparison between resistant and susceptible P. xylostella revealed three novel mutations including a glutamic acid to valine substitution (E1338D), a glutamine to leucine substitution (Q4594L) and an isoleucine to methionine substitution (I4790M) in highly conserved regions of RyR. Frequency analysis of all four mutations in this field population showed that the three …

A Case Of Cutaneous Larva Migrans Presenting In A Pregnant Patient., Kasie Kudrewicz, Kylee N Crittenden, Alison Himes

Women’s Health Articles

Cutaneous larva migrans (CLM) is a pruritic dermatitis caused by migration of the animal hookworm larvae into the epidermis. We present a case of CLM in a 31-year-old pregnant woman. The treatment of CLM relies on antihelminthic agents, such as thiabendazole, albendazole, and ivermectin. This case was interesting in that the standard treatment options previously mentioned were contraindicated owing to the patient's pregnancy. Cryotherapy with liquid nitrogen resulted in complete resolution of her lesion and symptoms.

Women In The Crowd Of Corporate Directors: Following, Walking Alone, And Meaningfully Contributing, Joan Macleod Heminway Oct 2014

Women In The Crowd Of Corporate Directors: Following, Walking Alone, And Meaningfully Contributing, Joan Macleod Heminway

Scholarly Works

With the thought that new perspectives often can be helpful in addressing long-standing unresolved questions, this article approaches an analysis of women’s roles on corporate boards of directors from the standpoint of crowd theory. Crowd theory — in reality, a group of theories — explains the behavior of people in crowds. Specifically, this article describes theories of the crowd from social psychology and applies them to the literature on female corporate directors, looking at the effects on both women as crowd members and boards as decision-making crowds.

Unfortunately, while the crowd theory perspective provides some insights, they are not altogether …

Educational, School, and Counseling Psychology Faculty Publications

African-American women may be susceptible to stressful events and adverse health outcomes as a result of their distinct social location at the intersection of gender and race. Here, racism and sexism are examined concurrently using survey data from 204 African-American women residing in a southeastern U.S. urban city. Associations among racism, sexism, and stressful events across social roles and contexts (i.e., social network loss, motherhood and childbirth, employment and finances, personal illness and injury, and victimization) are investigated. Then, the relationships among these stressors on psychological distress are compared, and a moderation model is explored. Findings suggest that racism and …


Troponin Leak Associated With Drug-Induced Methemoglobinemia., Robert D. Cannon Do, Michael Wagner, Jeanne L. Jacoby Md Oct 2014

Troponin Leak Associated With Drug-Induced Methemoglobinemia., Robert D. Cannon Do, Michael Wagner, Jeanne L. Jacoby Md

Department of Emergency Medicine

Drug-induced methemoglobinemia is a well-described entity but has not been previously associated with elevated troponins in the absence of cardiac symptoms. We report a case of a patient presenting to the emergency department (ED) with complaints related to an exacerbation of her long-standing cystitis. A low pulse oximetry reading prompted an evaluation, revealing a troponin leak, which peaked at 10 hours. Her methemoglobin level was found to be elevated at 11.4%, but a preexisting anemia apparently prevented the clinical recognition of cyanosis. The methemoglobinemia was determined to be secondary to her ingestion of phenazopyridine and trimethoprim-sulfa methoxizole. Although phenazopyridine and …
