Travis Orth, Jessica Paré, John E Froehlich
CONTEXT: Recent advances within the field of genetics are currently changing many of the methodologies in which medicine is practiced. These advances are also beginning to influence the manner in which physical therapy services are rendered. Rotator cuff pathology is one of the most common diagnoses treated by the sports physical therapist. The purpose of this commentary is to educate sports physical therapists on the recent advances regarding how genetics influences rotator cuff pathology, including rotator cuff tears, and provide a perspective on how this information will likely influence post-operative shoulder rehabilitation in the near future...

Previous research suggests that chocolate milk may be a beneficial recovery beverage, yet little is known about how athletes and students training for careers in sports science or health-related fields interpret recommended recovery beverage serving sizes. This study examined college students' ability to correctly apply serving size recommendations for chocolate milk and protein powder used during post-exercise recovery and assessed usual consumption of milk as a recovery beverage. College students (34 women, 39 men) poured the amount of chocolate milk they would consume within 90 minutes after exercise unaided and with the use of a serving size guide...

BACKGROUND: Muscle enzymes are cleared from the extracellular space by the lymphatic system, while smaller proteins enter the bloodstream directly. We investigated if manual lymphatic drainage (MLD), local cryotherapy (CRY), and rest (RST) differently affect the time course of creatine kinase (CK, 84 kDa) and heart-type fatty acid binding protein (h-FABP, 15 kDa) in the blood. DESIGN: Randomized controlled trial. METHODS: After 4x20 unilateral, eccentric accentuated knee extensions (with one-third of the maximal isometric force) 30 sports students randomly received either a 30 min MLD, CRY or they rested (RST) for the same amount of time...

BACKGROUND: Ovarian cancer is the most lethal gynecological cancer, almost 80% of all patients succumb the disease within 5 years of diagnosis. High mortality is caused especially by nonspecific symptoms, diagnosis in late stages and the absence of a specific biomarker. Currently, the most common diagnostic biomarkers are the membrane glycoprotein Cancer Antigen 125 (CA 125), the Human Epididymal Protein 4 (HE4) and the Carcinoembryonic Antigen (CAE). None of these biomarkers is specific only for ovarian cancer and increased levels may be caused by other diseases...

Nandrolone decanoate (ND), an anabolic-androgenic steroid prohibited in collegiate and professional sports, is associated with detrimental cardiovascular effects through redox-dependent mechanisms. We previously observed that high-dose short-term ND administration (15 mg/kg for 2 weeks) did not induce left heart ventricular hypertrophy and, paradoxically, improved postischemic response, whereas chronic ND treatment (5 mg/kg twice a week for 10 weeks) significantly reduced the cardioprotective effect of postconditioning, with an increase in infarct size and a decrease in cardiac performance...

Cyanobacterial blooms are global phenomena that can occur in calm and nutrient-rich (eutrophic) fresh and marine waters. Human exposure to cyanobacteria and their biologically active products is possible during water sports and various water activities, or by ingestion of contaminated water. Although the vast majority of harmful cyanobacterial products are confined to the interior of the cells, these are eventually released into the surrounding water following natural or artificially induced cell death. Electrochemical oxidation has been used here to damage cyanobacteria to halt their proliferation, and for microcystin degradation under in-vitro conditions...
