Sex differences exist in the risk of developing type 1 and type 2 diabetes, and in the risk of developing diabetes-associated complications. Sex differences in glucose homeostasis, islet and β cell biology, and peripheral insulin sensitivity have also b
Brain tissue is metabolically expensive. Consequently, the evolution of humans’ large brains must have occurred via concomitant shifts in energy expenditure and intake. Proposed mechanisms include dietary shifts such as cooking. Importantly, though, any
After the reactions were completed, the CT values were determined, and the relative level of mRNA was normalized to GAPDH or 18S rRNA and was calculated by the 2−ΔΔCT method. Calculation of the absolute levels of siRNAs in tissues A literature screen revealed that mice are estimated to ...
processing machines where uncertainty or information shapes systems’ collective behavior driven by non-linear convolution of intrinsic system’s properties and external noise (e.g. biology and environment, respectively). Thus, TE has been considered as an important and powerful tool to analyze causal...
Such accurate mapping of tree cover down to the level of individual trees and consistent among countries has the potential to redefine land use impacts in non-forest landscapes, move beyond the need for forest definitions, and build the basis for natural climate solutions and tree-related studies...
