OBJECTIVES To evaluate common factors associated in the development of acute renal failure (ARF) in Comrades Marathon runners. METHODS This was a retrospective case series of 4 runners hospitalised post-race with ARF in the 89 km 2010 Comrades Marathon. The outcome measures were incidence of analgesic use, levels of creatine phosphokinase (CPK) and degree of electrolyte supplementation (sodiu...

BACKGROUND The effects of consumption of isolated soy protein (ISP) for a chronic period (4 weeks) on exercise induced muscle damage (EIMD) in athletic population have never been explored. OBJECTIVES To examine the effects of ISP on muscle damage indices elicited via a bout of damaging exercise. PATIENTS AND METHODS Forty males (20 boxers, 20 cyclists) aged 18 - 28 years were randomly assig...

This study was designed to determine whether the supplement of energy compound could attenuate strain-induced damage to skeletal muscle in rats. Energy compound is a saline mixture of the following ingredients: ATP (10 mg), Coenzyme-A (50 units), Coenzyme-Q10 (50 mg), Cytochrome C (30 mg) and Vitamin B6 (50 mg). Experimental animals were injured in right gastrocnemius muscles by a strain injury...

A 36-year-old man came to the emergency department with acute onset of exertional chest pain. He had had no recent infections, and no cardiovascular risk factors were present. However, the patient had used a wheelchair since his mid-20s because of sporadic inclusion-body myositis, as established by muscle biopsy. There were no other physical findings.

The purpose of this study was to ascertain whether an oral, non-prescription, nutritional supplement compound composed of a proprietary alkali-buffered creatine monohydrate and cetylated fatty acids mixture (Kre-Celazine(®)) was efficacious in reducing or eliminating refractory pain and inflammation, without untoward effects, in Juvenile Rheumatoid Arthritis (JRA), which is also called Juvenile...

Background: The aim of the present study was to investigate the in vitro effects of mercury (Hg+2), lead (Pb+2), silver (Ag+2), tin (Sn+2), bismuth (Bi+3) and indium (In+3) ions on sperm creatine kinase. Methods: creatine kinase was isolated from human sperm homogenates after chromatography on a DEAE cellulose column. Results: At 60 µg ml-1 metal concentration, 70% of the creatine kinase activi...
