What is the Optimal Amount of Protein to Support Post-Exercise Skeletal Muscle Reconditioning in the Older Adult?


Sports Medicine |September 2016 | Abstract: Hyperaminoacidemia following protein ingestion enhances the anabolic effect of resistance-type exercise by increasing the stimulation of muscle protein synthesis and attenuating the exercise-mediated increase in muscle protein breakdown rates. Although factors such as the source of protein ingested and the timing of intake relative to exercise can impact post-exercise [...]

Neuromuscular electrical stimulation prior to presleep protein feeding stimulates the use of protein-derived amino acids for overnight muscle protein synthesis


Journal of Applied Physiology  | January 2017 |  Abstract: Short periods of muscle disuse result in substantial skeletal muscle atrophy. Recently, we showed that both neuromuscular electrical stimulation (NMES) as well as presleep dietary protein ingestion represent effective strategies to stimulate muscle protein synthesis rates. In this study, we test our hypothesis that NMES can [...]

Ingestion of Wheat Protein Increases In Vivo Muscle Protein Synthesis Rates in Healthy Older Men in a Randomized Trial


Journal of Nutrition | September 2016 | Abstract: BACKGROUND: Muscle mass maintenance is largely regulated by basal muscle protein synthesis and the capacity to stimulate muscle protein synthesis after food intake. The postprandial muscle protein synthetic response is modulated by the amount, source, and type of protein consumed. It has been suggested that plant-based [...]

Muscle fibre capillarization is a critical factor in muscle fibre hypertrophy during resistance exercise training in older men


Journal of Cachexia, Sarcopenia and Muscle | 04-08-2016| Abstract: Background: Adequate muscle fiber perfusion is critical for the maintenance of muscle mass, it is essential in the rapid delivery of oxygen, nutrients and growth factors to the muscle, stimulating muscle fiber growth. Muscle fiber capillarization is known to decrease substantially with advancing age. However, whether [...]

Age-related accrual of methylomic variability is linked to fundamental ageing mechanisms


Genome Biology | September 2016 | Background Epigenetic change is a hallmark of ageing but its link to ageing mechanisms in humans remains poorly understood. While DNA methylation at many CpG sites closely tracks chronological age, DNA methylation changes relevant to biological age are expected to gradually dissociate from chronological age, mirroring the increased heterogeneity [...]

Ectopic miR-125a Expression Induces Long-Term Repopulating Stem Cell Capacity in Mouse and Human Hematopoietic Progenitors  


Cell | September 2016| Summary Umbilical cord blood (CB) is a convenient and broadly used source of hematopoietic stem cells (HSCs) for allogeneic stem cell transplantation. However, limiting numbers of HSCs remain a major constraint for its clinical application. Although one feasible option would be to expand HSCs to improve therapeutic outcome, available protocols and the [...]
