In terms of surface temperature variation, while pedal surfaces were important in regulating heat loss in Natal and Damaraland mole-rats at high ambient temperatures, the ventral surface was important for heat dissipation in Damaraland and highveld mole-rats. This study provides evidence of the variation and limitations of thermo-physiological mechanisms for three mole-rat species relative to their habitats. Information on physiological adaptations to particular habitats may inform predictive modelling of species movements, declines, and extinctions in response to a changing environment, such as climate change. Temperature is one of the key environmental factors affecting the eco-physiological responses of living organisms and is considered one of the utmost crucial factors in shaping the fundamental niche of a species. The purpose of the present study is to delineate the physiological response and changes in energy allocation strategy of Bellamya bengalensis, a freshwater gastropod in the anticipated summer elevated temperature in the future by measuring the growth, body conditions (change in total weight, change in organ to flesh weight ratio), physiological energetics (ingestion rate, absorption rate, respiration rate, excretion rate and Scope for Growth) and thermal performance, Arrhenius breakpoint temperature (ABT), thermal critical maxima (CTmax), warming tolerance (WT) as well as thermal safety margin (TSM) through a mesocosm experiment. We exposed the animals to three different temperatures, 25 °C (average habitat temperature for this animal) and elevated temperatures 30 °C, 35 °C for 30 days and changes in energy budget were measured twice (on 15th and 30th day). Significant changes were observed in body conditions as well as physiological energetics. The total body weight as well as the organ/flesh weight ratio, ingestion followed by absorption rate decreased whereas, respiration and excretion rate increased with elevated temperature treatments resulting in a negative Scope for Growth in adverse conditions. Though no profound impact was found on ABT/CTmax, the peak of thermal curve was considerably declined for animals that were reared in higher temperature treatments. Our data reflects that thermal stress greatly impact the physiological functioning and growth patterns of B. bengalensis which might jeopardize the freshwater ecosystem functioning in future climate change scenario. Heat shock proteins (HSPs) greatly contribute to insect stress tolerance and enhance survival and adaptation in severe environmental conditions. To investigate the potential roles of HSPs in the spruce budworm, Choristoneura fumiferana (L.), an important native pest of forests in North America, we found eight ATP-dependent HSP transcripts (CfHSPs). Based on molecular characteristics, the identified HSP genes were classified into HSP70 and HSP90 families, and phylogenetic results showed that they had orthologues in other insects. The transcript levels of these HSPs were measured using RT-qPCR under normal and stressful conditions in the laboratory. Under normal conditions, three HSP genes were consistently expressed in all life stages, whereas expression of the other five genes was dependent on the developmental stage. In the larvae, most CfHSP transcripts displayed similar expression levels among different tissues. Under heat shock conditions, one HSP70 gene and one HSP90 gene were upregulated in all life stages. One HSP70 gene was upregulated after cold injury in the larval stage. With starvation, HSP gene expression exhibited complex expression patterns; most of them were downregulated. These results suggest that the ATP-dependent HSPs have multiple roles during normal development as well as under stressful conditions including heat, cold injury and starvation. selleck chemicals llc Crown All rights reserved.INTRODUCTION The effect of hyperthermia on the antioxidant system in the human organism is well known. AIM The objective of this study was to observe the effects of heat on the concentration of Se and Zn, elements related to antioxidant systems. METHODS Twenty-nine subjects voluntarily participated in this study. They were divided into a control group (CG; n = 14) and an experimental group (EG; n = 15). All of them underwent two incremental tests until exhaustion in normothermia (22 °C, 20-40%RH) and hyperthermia (42 °C, 20-40%RH). EG experienced nine sessions of repeated heat exposure at high temperatures (100 °C, 20%RH) for three weeks (HEHT). After the intervention, the initial measurements were repeated. Urine and blood samples were collected before and after each test. Additionally, sweat samples were collected after tests in hyperthermia. RESULTS There were no significant changes in serum. An increase in the elimination of Zn and Se in EG was observed in urine after HEHT (p  less then  .05). The elimination of Zn by sweating decreased after HEHT in EG (p  less then  .05). CONCLUSIONS Exposure to heat at high temperatures increases the urinary excretion of Se and Zn. Transmembrane Bax Inhibitor Motif-containing 6 (TMBIM6) gene acts as calcium leak channel and negatively regulates autophagy and autophagosome formation. The TMBIM6 gene was amplified and searched for variation in three different goat populations (i.e. Black Bengal, Ganjam and Raighar) of Odisha state of the India. The result indicated two substitutions i.e. 55th position (C55T) and 95th position (C95A) in the amplified region of the gene resulting in change of amino acids (Leu > Phe and Thr > Asn). The identified SNPs were combined to form haplotypes and animals were grouped accordingly. Structural analysis showed minor changes (5%) in between mutant and wild TMBIM6 protein structures. However, any functional variation could not be identified with respect to the calcium ligand and open pore state. But an alteration of calcium binding site was found. The binding interaction of calcium with the TMBIM6 protein was hydrophobic in nature in closed state whereas hydrophilic in open pore stage. The stress releasing function was the result of calcium leakage controlled by amino acids coded by exon 4 and exon 5 regions of TMBIM6 gene. The effect of breed and haplotype on cardiopulmonary traits was studied. The data on cardiopulmonary traits of body i.e. rectal temperature, skin temperature, heart rate and respiration rate were recorded when ambient temperature usually remained the highest. The statistical analysis showed, significant difference in rectal temperature, skin temperature and respiration rate among these goat populations. The haplotypes (CC and TA) were found to have a significant (P  less then  0.05) effect on rectal temperature, skin temperature and respiration rate. However, any such significant effect could not be identified in recorded heart rate. The objective of the present study to identify the genetic variations in TMBIM6 gene having significant effect on cardiopulmonary traits which can be further uses as the molecular markers to improve heat tolerance mechanism in goats.
