PURPOSE: The purpose of this study was to investigate the effects of 12 weeks of protein supplementation and Autoregulatory Progressive Resistance Exercise (APRE) training on measures of body composition, muscular performance, and free testosterone in middle-aged men. METHODS: Untrained males (n = 35; 43.3 ± 6.6 years) participated in this study. Lean mass (LM) and fat mass (FM) were measured via Dual Energy X-ray Absorptiometry (DEXA), while strength was measured utilizing one repetition maximum (1RM), endurance measured using maximum repetitions completed (REPS) at 75% 1RM for the bench and leg press, and free testosterone was measured using changes in serum …

Pannexin 3 (Panx3) is a mechanosensitive, channel-forming glycoprotein implicated in the progression of post-traumatic osteoarthritis. Despite evidence for Panx3 expression in intervertebral discs (IVDs), its function here remained unknown. Using Panx3-/- mice, this study investigated the role of Panx3 in age-associated and injury-induced models of IVD degeneration. While loss of Panx3 did not significantly impact the progression of age-associated IVD degeneration, it was associated with a protective phenotype in an injury model of IVD degeneration, specifically in the annulus fibrosus (AF). Following IVD injury, WT mice showed an accumulation of enlarged cells that appeared to contribute to disrupted AF …

As age increases, there is evidence that people tend to pay less attention to negative information, pay more attention to positive information, or both. There are many theoretical accounts that attempt to explain this positivity bias. In the current study, I examined positivity effects across the adult lifespan by evaluating competing predictions of two theories: Socioemotional Selectivity Theory, which is based in motivation, and Dynamic Integration Theory, which is based in capacity. Computer mouse tracking was used to examine effects across levels of Valence (negative, neutral, and positive) and Arousal (low, medium, and high) in an emotional Stroop task. Participants …
