Consistent responses of coral microbiome to acute and chronic heat stress exposures
Marine Environmental Research, 2023Frequent and intense heat waves lead to bleaching and even death of reef-building corals, and the thermal tolerance ultimately depends on the genetic composition of the holobiont. Here, we compared the effects of acute and chronic heat stress exposures on coral Porites cylindrica holobiont.

ABSTRACTIncreasingly commonplace in cities, extreme heat events introduce multi-stress vulnerability, affecting people’s health and well-being, financial situation, mobility, social relations, and access to basic services. Planning to reduce heat vulnerability has become part of government business and to some extent community-level responses, cutting ...

Abstract 1. Glutathione peroxidase activity and serum malondialdehyde of heat-stressed broilers were increased in the early period of heat exposure, and then these parameters decreased. 2. The lesion scores of bursa of Fabricius in heat-stressed broilers were increased and decreased in accordance with the activity of glutathione peroxidase ...

Journal of the American Pharmaceutical Association (Scientific ed.), 1954
The effect of psychic stress upon the dermal permeability of chronically heat- and humidity-stressed rats was studied. Permeability was increased by chronic and acute psychic stress. The increase was maintained in the acutely stressed rats twenty-seven days after the stress, the last day of the study.

Transcriptional profiling of mouse liver in response to chronic heat stress
Journal of Thermal Biology, 2008Abstract Mice were used to study the effects of chronic heat stress on hepatic gene expression. Twenty-five mice were allocated to either chronic heat stress (34 °C) or control (24 °C) conditions for a period of 2 weeks from 47 to 60 d of age. Nineteen genes differentially expressed in liver were identified using DNA microarrays.

Effects of chronic heat stress on mRNA and miRNA expressions in dairy cows
Gene, 2020Heat stress has a negative impact on dairy cow productivity. In order to reveal the mechanisms of heat-stress response, the mRNA and miRNA expression profiles of five cows under chronic heat-stress and thermoneutral conditions were assayed in blood by high-throughput sequencing technology.

The Hydrological Urban Heat Island: Determinants of Acute and Chronic Heat Stress in Urban Streams
JAWRA Journal of the American Water Resources Association, 2021AbstractDuring and after rainfall events, the interaction of precipitation with hot urban pavements leads to hot runoff, and its merger with urban streams can result in an abrupt change in water temperature that can harm aquatic ecosystems. To understand this phenomenon and its relation to land cover and hydrometeorological parameters, we analyzed data

Expression dynamics of HSP70 during chronic heat stress in Tharparkar cattle
International Journal of Biometeorology, 2016Six male Tharparkar cattle aged 2-3 years were selected for the study. The animals were acclimatized in the psychrometric chamber at thermoneutral zone (TNZ) for 15 days and then exposed to 42 °C temperature up to 23 days followed by 12 days of recovery period.

Chronic heat stress disrupts foraging motivation in honey bees
Journal of Insect PhysiologyPollinator mortality is a global concern linked to climate change; however, the complex responses underlying heat stress in honey bees are not yet fully understood. This study investigated the impact of chronic heat stress on honey bee appetitive motivation and related physiological processes that are essential for colony functioning.

Proteomic changes of the porcine skeletal muscle in response to chronic heat stress
Journal of the Science of Food and Agriculture, 2018AbstractBACKGROUNDHeat stress (HS) has an adverse effect on meat quality; however, the underlying molecular mechanisms altering meat quality due to muscle responses to stress remain unclear. Sixteen castrated male crossbreeds between Landrace × Yorkshire sows and Duroc boars (79.00 ± 1.50 kg body weight) were exposed to either thermal neutral (22 °C, n
