ABSTRACT
PURPOSE: The purpose of this study was to evaluate the effect of fluid loss following hemodialysis (HD) on tibialis anterior (TA) strength in participants with end-stage renal disease. Issues concerning measures of skeletal muscle hydration and efficacy of exercise as an anabolic intervention were also addressed.
METHODS: Data from published literature were combined in a meta-analysis to establish efficacy of exercise in participants on HD. Three clinical studies were undertaken using data acquired from healthy volunteers and participants on HD. Hydration of the calf muscles was estimated using bioelectrical impedance spectroscopy (BIS) [extracellular (ECF) and intracellular (ICF) fluid] …

Exercise induces cytoprotective stress proteins in blood vessels (BV) and skeletal myofibres. The localization and extent of induction with different exercise intensities is unclear. Rats (n=10 per group) were run at high (HIEX; 30m/min) versus low-intensity exercise (LOEX; 15m/min) for 1hr, sacrificed 24hr later. Sections of the white portion of the vastus were immunofluorescently stained for Hsp70 and Hsp90. It was hypothesized that: 1) a greater abundance of Hsp70 and Hsp90 would be observed in BVs following HIEX, 2) due to earlier recruitment, larger BVs would have a more robust response than small BVs, 3) more myofibres surrounding BVs expressing …

The cerebral metabolic rate of oxygen (CMRO2) has been shown to be an early indicator of hypoxia-ischemia (HI); however, the mechanisms controlling post-HI CMRO2 are not clear. One potential mechanism is the activation of the adenosine A1 receptor due to increased adenosine concentrations during the insult. The present study investigated if the specific adenosine A1 antagonist, DPCPX, would reduce the typical reduction in CMRO2 and electrical cortical activity following HI. Measurements of CMRO2 and electrical cortical activity were obtained on piglets by near-infrared spectroscopy (NIRS) and amplitude-integrated electroencephalography (aEEG), respectively. The post-HI measurements of CMRO2 and mean aEEG background voltage …
