Heat stress in older individuals and patients with common chronic diseases [PDF]

Canadian Medical Association Journal, 2009
Scientists have predicted that extremes in climate are likely to increase in frequency and severity. [1][1] These changes may have a direct impact on population health, as heat waves can exceed the physiological adaptive capacity of vulnerable population groups.

Effects of Chronic and Acute Heat Stress on the Cardiac Expression of Antioxidative and Anti-Inflammatory Genes in Chicks [PDF]

Brazilian Journal of Poultry Science
Heat stress can affect several biological pathways. This study aimed to compare the effects of chronic and acute heat stress on the oxidative status and inflammatory responses of chick’s hearts. Chronic and acute heat stress were induced in chicks, heart

Liver transcriptome response to hyperthermic stress in three distinct chicken lines [PDF]

, 2016
Background High ambient temperatures cause stress in poultry, especially for broiler lines, which are genetically selected for rapid muscle growth. RNA-seq technology provides powerful insights into environmental response from a highly metabolic tissue ...

Effects of l-leucine in ovo feeding on thermotolerance, growth and amino acid metabolism under heat stress in broilers

Animal, 2020
Recently, we found that in ovo feeding of l-leucine (l-Leu) afforded thermotolerance, stimulated lipid metabolism and modified amino acid metabolism in male broiler chicks.

Differential expression of heat shock transcription factors and heat shock proteins after acute and chronic heat stress in laying chickens (Gallus gallus). [PDF]

PLoS ONE, 2014
Heat stress due to high environmental temperature negatively influences animal performances. To better understand the biological impact of heat stress, laying broiler breeder chickens were subjected either to acute (step-wisely increasing temperature ...

Potential biomarkers for chronic seasonal heat stress in Kagoshima Berkshire pigs reared in the subtropical region

Journal of Veterinary Research, 2022
Potential biomarkers for chronic seasonal heat stress in Kagoshima Berkshire pigs reared in the subtropical region were investigated by comparing the biomarker changes in the summer (a period of chronic heat stress) and winter (a thermoneutral period ...
