Skeletal muscle mass is regulated by a balance between muscle protein synthesis (MPS) and muscle protein breakdown (MPB). In healthy humans, MPS is more sensitive (varying 4-5 times more than MPB) to changes in protein feeding and loading rendering it the primary locus determining gains in muscle mass. Performing resistance exercise (RE) followed by the(More)
We reported, using a unilateral resistance training (RT) model, that training with high or low loads (mass per repetition) resulted in similar muscle hypertrophy and strength improvements in RT-naïve subjects. Here we aimed to determine whether the same was true in men with previous RT experience using a whole-body RT program and whether postexercise(More)
Valved holding chambers (VHCs) are widely prescribed for use with pressurized metered dose inhalers (pMDIs) for the treatment of respiratory disease by aerosol therapy. The facemask is the preferred patient interface for use by infants and small children, as well as by geriatric patients, due primarily to poor coordination skills. However, care is required(More)
Evolution of flight in maniraptoran dinosaurs is marked by the acquisition of distinct avian characters, such as feathers, as seen in Archaeopteryx from the Solnhofen limestone. These rare fossils were pivotal in confirming the dinosauria-avian lineage. One of the key derived avian characters is the possession of feathers, details of which were remarkably(More)
The peripheral cytoplasm of the unfertilized sea urchin egg contains approximately 18,000 cortical granules. These granules remain monolayered within the normal boundaries of the cortex when the egg is centrifuged at forces sufficient to stratify other intracellular inclusions. Exposure of unfertilized eggs to the microfilament disrupting agent,(More)
Sensitivity of calcium-selective electrodes heretofore has been limited to calcium concentrations above 10(-8) M in the absence of competing ions. We describe the use of calcium buffers to stabilize the free calcium in the reference electrode. Electrode calibration is linear to 10(-8) M and is curvilinear to 10(-11) M in the presence of 0.1 M ionic(More)
PURPOSE Discrepancies regarding the effect of resistance exercise training (RET) on arterial stiffness have led to uncertainty regarding the effect of RET on cardiovascular health. Confounding our understanding in this area are the roles of the following: load (heavier vs lighter), participant cardiovascular health, and arterial stiffness assessment method.(More)
PURPOSE Self-myofascial release (SMR) is a common exercise and therapeutic modality shown to induce acute improvements in joint range of motion (ROM) and recovery; however, no long-term studies have been conducted. Static stretching (SS) is the most common method used to increase joint ROM and decrease muscle stiffness. It was hypothesized that SMR paired(More)
OBJECTIVE We performed a systematic review, meta-analysis and meta-regression to determine if dietary protein supplementation augments resistance exercise training (RET)-induced gains in muscle mass and strength. DATA SOURCES A systematic search of Medline, Embase, CINAHL and SportDiscus. ELIGIBILITY CRITERIA Only randomised controlled trials with RET(More)
Uptake and phosphorylation of exogenously supplied thymidine are stimulated in Strongylocentrotus purpuratus eggs after fertilization. Before fertilization, the rate of uptake is low and less than 10% of the thymidine entering the egg is phosphorylated. After fertilization, the rate of uptake increases over 50-fold and greater than 90% of the thymidine is(More)
