Preparing For A National Weightlifting Championships: A Case Series, S. Kyle Travis, Satoshi Mizuguchi, Michael H. Stone, William A. Sands, Caleb D. Bazyler

Caleb D. Bazyler

INTRODUCTION: Monitoring an athlete’s psychological, physiological, and performance level is important when preparing for a major competition. No study to date has tracked a high-level weightlifter peaking for a major competition all the way up to the day of competition. Assessing performance at a competition is vital to ascertain if the athlete has reached a peaked and if peak performance will actually be expressed during the competition. PURPOSE: Therefore, the purpose of this study was to determine when peak jumping performance was achieved and whether psychological or physiological variables explained any jump performance changes in a high-level female weightlifter preparing …

Using Mixed Methods To Measure The Perception Of Community Capacity In An Academic–Community Partnership For A Walking Intervention, Charkarra Anderson-Lewis, Diana Castellanos, Arnecca Byrd, Karen Zynda, Alicia Sample, Vickie Reed, Mary Beard, Latessa Minor, Kathleen Yadrick

H.U.B. City Steps is a 5-year community-based participatory research walking intervention designed to help lower blood pressure in a majority African American population in southern Mississippi via community collaboration and capacity building, increased walking, culturally tailored health education sessions, and motivational interviewing. Building community capacity for physical activity is a key component of this intervention. Qualitative and quantitative methods have been used to assess how project stakeholders perceive the community capacity-building efforts of the project. This article illustrates the baseline results of this mixed methods approach from the perspective of three groups of stakeholders: project researchers and staff, community advisory …

Microrna Cargo Of Extracellular Vesicles From Alcohol-Exposed Monocytes Signals Naive Monocytes To Differentiate Into M2 Macrophages, Banishree Saha, Fatemeh Momen-Heravi, Karen Kodys, Gyongyi Szabo

Membrane-coated extracellular vesicles (EVs) released by cells can serve as vehicles for delivery of biological materials and signals. Recently, we demonstrated that alcohol-treated hepatocytes cross-talk with immune cells via exosomes containing microRNA (miRNAs). Here, we hypothesized that alcohol-exposed monocytes can communicate with naive monocytes via EVs. We observed increased numbers of EVs, mostly exosomes, secreted by primary human monocytes and THP-1 monocytic cells in the presence of alcohol in a concentration- and time-dependent manner. EVs derived from alcohol-treated monocytes stimulated naive monocytes to polarize into M2 macrophages as indicated by increased surface expression of CD68 (macrophage marker), M2 markers (CD206 …

Teaching Stress Physiology Using Zebrafish (Danio Rerio), Michael Cooper, Shree Dhawale, Ahmed Mustafa

Ahmed Mustafa Dr.

A straightforward and inexpensive laboratory experiment is presented that investigates the physiological stress response of zebrafish after a 5 °C increase in water temperature. This experiment is designed for an undergraduate physiology lab and allows students to learn the scientific method and relevant laboratory techniques without causing significant stress to animals. An additional experimental design and a set of additional questions for lab report are also included.

Outcomes Of Early Versus Late Nephrology Referral In Chronic Kidney Disease – A Systematic Review, Neil A. Smart Assoc. Prof.

Neil Smart

Background As late provision of specialist care, prior to starting dialysis therapy, is believed to be associated with increased morbidity and mortality, a systematic review was undertaken to evaluate clinical outcomes relating to early versus late referral of patients to nephrology services.

Methods: Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE and EMBASE were searched up until September 2008 for studies of early versus late nephrology referral in adult (>18 years) patients with chronic kidney disease. Early referral was defined by the time period, at which patients were referred to a nephrologist.

Findings: No randomized, controlled trials were found. …
