REVIEW: Evidence supporting the 'preparation for oxidative stress' (POS) strategy in animals in their natural environment
Comp Biochem Physiol A Mol Integr Physiol. 2024 Mar 21:111626. doi: 10.1016/j.cbpa.2024.111626. Online ahead of print.ABSTRACTHypometabolism is a common strategy employed by resilient species to withstand environmental stressors that would be life-threatening for other organisms. Under conditions such as hypoxia/anoxia, temperature and salinity stress, or seasonal changes (e.g. hibernation, estivation), stress-tolerant species down-regulate pathways to decrease energy expenditures until the return of less challenging conditions. However, it is with the return of these more favorable conditions and the reactivation of basal...

Impairment on fillet fatty acid profile and oxidative damage in pirarucu, Arapaima gigas, acutely exposed to extreme ambient temperature
The objective of this work was to determine whether antioxidant defense system is able to prevent muscle oxidative damage of pirarucu exposed 96 h to extreme climate scenario, as well as the effects of this exposition on muscle fatty acid levels. Lipid peroxidation and reactive oxygen species significantly increase in the muscle of pirarucus exposed to an extreme climate scenario compared to control, while muscle superoxide dismutase, catalase, and glutathione peroxidase were significantly lower. Total amount of saturated fatty acids (SFAs) was significantly higher in pirarucu exposed to an extreme climate scenario compare...

Hydration state does not affect selected body temperature during gravidity or gravidity duration in pythons (Antaresia childreni)
Comp Biochem Physiol A Mol Integr Physiol. 2024 Mar 8:111624. doi: 10.1016/j.cbpa.2024.111624. Online ahead of print.ABSTRACTThe embryonic development of many ectothermic species are highly sensitive to temperature and typically have a higher thermal optima than do most other physiological processes. Thus, female ectotherms often maintain a higher and more carefully controlled body temperature when she is supporting developing embryos (early development in oviparous species, throughout development in viviparous species). Considering the positive correlation between body temperature and evaporative water loss, this response...

Effects of dietary calcium (Ca < sup > 2+ < /sup > ) and blood feeding on the immunochemical expression of the plasma membrane Ca < sup > 2+ < /sup > -ATPase (PMCA) in Malpighian tubules of adult female mosquitoes (Aedes aegypti)
Comp Biochem Physiol A Mol Integr Physiol. 2024 Mar 6:111623. doi: 10.1016/j.cbpa.2024.111623. Online ahead of print.ABSTRACTInsect Malpighian tubules contribute to Ca2+ homeostasis via Ca2+ storage in intracellular compartments, Ca2+ secretion into the tubule lumen, and Ca2+ reabsorption into the hemolymph. A plasma membrane Ca2+-ATPase (PMCA) is hypothesized to be a Ca2+-transporter involved in renal Ca2+ transport of insects, however few studies have investigated its immunochemical expression in Malpighian tubules. Here we characterized the abundance and localization of PMCA-like immunoreactivity in Malpighian tubules o...
