BACKGROUND: Myostatin negatively regulates muscle growth, and its inhibition by suitable proteins can increase muscle bulk and exercise performance. However, the reference values of serum myostatin in athletes performing strength training are still lacking. METHODS: A cross-sectional study recruiting28 male collegiate athletes performing strength training and 29 age-matched normal controls was conducted. The serum concentration of myostatin and insulin-like growth factor 1 (IGF-1), grip strength, and body composition were the main outcome measures...

Azahara Barra-Jiménez, Laura Ragni
Secondary growth, the increase in girth of plant organs, is primarily driven by the vascular and cork cambium. In perennial dicotyledons and gymnosperms, it represents a major source of biomass accumulation in the form of wood. However, the molecular framework underlying secondary growth is largely based on studies in the annual herbaceous plant Arabidopsis thaliana. In this review, we will focus on a selection of major regulators of stem secondary growth, which have recently been shown to play a role in woody species...

The objective of this study was to investigate the effects of grain sources and forage provision on growth performance, blood metabolites, and feeding behaviors of dairy calves. Sixty 3-d-old Holstein dairy calves (42.2 ± 2.5 kg of body weight) were used in a 2 × 3 factorial arrangement with the factors being grain sources (barley and corn) and forage provision (no forage, alfalfa hay, and corn silage). Individually housed calves were randomly assigned (n = 10 calves per treatment: 5 males and 5 females) to 6 treatments: (1) barley grain (BG) without forage supplement, (2) BG with alfalfa hay (AH) supplementation, (3) BG with corn silage (CS) supplementation, (4) corn grain (CG) without forage supplement, (5) CG with AH supplementation, and (6) CG with CS supplementation...

With an incidence of 1:500, denial of pregnancy is a rather frequent incident in obstetrics. Strikingly, in our society, this issue is placed under a taboo. Reasons might be our moral values and socialization. Since pregnancy and motherhood have to be associated with joy, other sensations are often perceived as socially not accepted and thus denied. A similar phenomenon exists e. g. with postnatal depression.In all existing studies on denial of pregnancy, it was proven that there are no significant at-risk groups...

OBJECTIVES: To examine the associations between absolute and relative handgrip strength (HGS) and physical performance. METHODS: A total of 135 old men aged 70-89 years had muscle thickness (MT) measured by ultrasound at anterior forearm (MT-ulna). Maximum voluntary HGS was measured for the dominant hand. Relative HGS was calculated as ratios of HGS to MT-ulna (HGS/MT-ulna, kg/cm), HGS to forearm girth (HGS/forearm-girth, kg/cm), and HGS to body mass (HGS/body mass, kg/kg)...

Secondary growth occurs in dicotyledons and gymnosperms, and results in an increased girth of plant organs. It is driven primarily by the vascular cambium, which produces thousands of cells throughout the life of several plant species. For instance, even in the small herbaceous model plant Arabidopsis, manual quantification of this massive process is impractical. Here, we provide a comprehensive overview of current methods used to measure radial growth. We discuss the issues and problematics related to its quantification...

Recent epidemiological studies show that the prevalence of sleep-disordered breathing seems to be higher than previously estimated in the middle to older aged general population with approximatively 49% of men and 23% of women being affected. This higher than expected prevalence of sleep-disordered breathing seems to be due to the high sensitivity of current recording techniques and to the new and more inclusive definition of respiratory events (hypopnea definition in particular). Male sex, age, and truncal obesity (large neck girth, high waist to hip ratio) are the main risk factors for sleep-disordered breathing...

Trade-offs between pre- and postcopulatory traits influence their evolution, and male expenditure on such traits is predicted to depend on the number of competitors, the benefits from investing in weapons, and the risk and intensity of sperm competition. Males of the chorusing frog Crinia georgiana use their arms as weapons in contest competition. Previously, we showed that increased numbers of rivals elevated the risk and intensity of sperm competition due to multimale amplexus, and caused a reversal in the direction of precopulatory selection on arm girth...
