Physical performance during energy deficiency in humans: An evolutionary perspective
Comp Biochem Physiol A Mol Integr Physiol. 2023 Jul 3:111473. doi: 10.1016/j.cbpa.2023.111473. Online ahead of print.ABSTRACTEnergy deficiency profoundly disrupts normal endocrinology, metabolism, and physiology, resulting in an orchestrated response for energy preservation. As such, despite energy deficit is typically thought as positive for weight-loss and treatment of cardiometabolic diseases during the current obesity pandemic, in the context of contemporary sports and exercise nutrition, chronic energy deficiency is associated to negative health and athletic performance consequences. However, the evidence of energy de...

Functional transcriptome reveals hepatopancreatic lipid metabolism during the molting cycle of the Chinese mitten crab Eriocheir sinensis
In conclusion, these results showed that TAG is the major lipid deposition during inter- and pre-molt stages, and the most genes are related to the fatty acids and TAG metabolism in the hepatopancreas during the molting cycle of E. sinensis.PMID:37406959 | DOI:10.1016/j.cbpa.2023.111474 (Source: Comparative Biochemistry and Physiology.

Long term stability of corticosterone in feathers
Comp Biochem Physiol A Mol Integr Physiol. 2023 Jun 28;283:111472. doi: 10.1016/j.cbpa.2023.111472. Online ahead of print.ABSTRACTMeasuring corticosterone in feathers allows researchers to make long-term, retrospective assessments of physiology with non-invasive sampling. To date, there is little evidence that steroids degrade within the feather matrix, however this has yet to be determined from the same sample over many years. In 2009, we made a pool of European starling (Sturnus vulgaris) feathers that had been ground to a homogenous powder using a ball mill and stored on a laboratory bench. Over the past 14 years, a sub...
