miRNA-1 regulation is necessary for mechanical overload-induced muscle hypertrophy in male mice.

MicroRNAs (miRNAs) are small, noncoding RNAs that play a critical role in regulating gene expression post-transcriptionally. They are involved in various developmental and physiological processes, and their dysregulation is linked to various diseases. Skeletal muscle-specific miRNAs, including miR-1, play a crucial role in the development and maintenance of skeletal muscle.

Comparing Time to Recovery Between Initial and Repeat Concussion in Athletes.

Objective: Compare time to recovery between initial and repeat concussions.

Design: Retrospective review of electronic medical record.

Setting: An interdisciplinary concussion clinic.

Part II. Common questions and misconceptions about creatine supplementation: what does the scientific evidence really show?

Creatine monohydrate supplementation (CrM) is a safe and effective intervention for improving certain aspects of sport, exercise performance, and health across the lifespan. Despite its evidence-based pedigree, several questions and misconceptions about CrM remain. To initially address some of these concerns, our group published a narrative review in 2021 discussing the scientific evidence as to whether CrM leads to water retention and fat accumulation, is a steroid, causes hair loss, dehydration or muscle cramping, adversely affects renal and liver function, and if CrM is safe and/or effective for children, adolescents, biological females, and older adults.
