The purpose of this study was to determine whether levels of interleukin-6 (IL-6) in childhood are related to insulin resistance in adolescence. Further, to explore how fatness and cardiorespiratory fitness (VO(2peak)) moderate this relationship. Methods. 292 nine-year-old children (n = 292) were followed for 4 years. Anthropometrics and VO(2peak) were measured. Fasting blood samples were analy...

We aimed to reduce the dimensionality of quantitative traits in pigs applying factor analysis. Quantitative variables were collected, and analysis extracted five factors with biological meaning related performance, carcass quality, yield, meat initial pH. These posteriorly used as dependent variable evaluate effects genetic groups (Piau, Duroc, Pietrain crossbreds), nutritional plans (low, medi...

Low birth weight is a well-established risk factor for type 2 diabetes, but the risk at high birth weight levels remains uncertain. Potential sex differences in the associations are unexplored. We investigated whether sex influences the association of birth weight and adult type 2 diabetes, using a cohort of 113,801 men and 109,298 women, born 1936-1983, from the Copenhagen School Health Record...

Traditional models predict that organisms should allocate to sex based on their condition relative to the condition of their competitors, tracking shifts in mean condition in fluctuating environments, and maintaining an equilibrium sex ratio. In contrast, when individuals are constrained to define their condition absolutely, environmental fluctuations induce fluctuating sex ratios and the evolu...

Abstract Climate change threatens species with temperature-dependent sex determination as further warming could result in extremely biased ratios or offspring of only one sex. Among the possible adaptations sea turtles to climate change, are behavioral responses toward nesting cooler areas. We analyzed patterns East Pacific green ( Chelonia mydas ) Costa Rica determine occurrence nest-site sele...
