Heat stress and copper supplementation in pigs

California Agriculture, 1989
Controlled feeding trials at UC Davis found no connection between temperature stress and response to copper supplementation, but confirmed overall effects of heat stress on pigs.

A comparative analysis of accelerating humid and dry heat stress in India

Environmental Research Communications
Extreme humid heat stress poses distinct challenges to human health and productivity that cannot be mitigated solely by heat action plans designed for dry heat stress. This study investigates the trends in extreme heat stress, differentiating between dry

TECHNIQUES TO MINIMIZE THE EFFECTS OF ACUTE HEAT STRESS OR CHRONIC IN BROILERS [PDF]

Brazilian Journal of Poultry Science, 2019
High environmental temperature is limiting factor in broiler production. In order to minimize the undesirable consequences of acute or chronic heat stress, the techniques of fixed dietary electrolyte balance and early heat conditioning were evaluated ...

Etoposide‐induced cancer cell death: roles of mitochondrial VDAC1 and calpain, and resistance mechanisms

Molecular Oncology, EarlyView.
The complex mode of action of the topoisomerase II inhibitor etoposide in triggering apoptosis involves several mechanisms: overexpression of the mitochondrial protein VDAC1, leading to its oligomerization and formation of a large channel that mediates the release of pro‐apoptotic protein; and overexpression of the apoptosis regulators p53, Bax, and ...

Sprinkling cattle for control of heat stress

California Agriculture, 1973
Sprinkling cattle, under shades, during the summer in the Imperial Valley for 1 minute every 30 minutes when the temperature was above 80°F (27°C)—resulted in significantly higher feed consumption and rate of gain, compared with cattle under shades but ...

Some aspects of heat stress on the plasticity of skeletal muscle cells

Journal of Physical Fitness and Sports Medicine, 2012
Hypertrophic stimuli, such as strength training and exercise, induce the up-regulation of heat shock proteins (HSPs), called stress proteins, in skeletal muscles.

Spectral analysis on transport budgets of turbulent heat fluxes in plane Couette turbulence [PDF]

arXiv, 2022
In recent years, scale-by-scale energy transport in wall turbulence has been intensively studied, and the complex spatial and interscale transfer of turbulent energy has been investigated. As the enhancement of heat transfer is one of the most important aspects of turbulence from an engineering perspective, it is also important to study how turbulent ...

Molecular and functional profiling unravels targetable vulnerabilities in colorectal cancer

Molecular Oncology, EarlyView.
We used whole exome and RNA‐sequencing to profile divergent genomic and transcriptomic landscapes of microsatellite stable (MSS) and microsatellite instable (MSI) colorectal cancer. Alterations were classified using a computational score for integrative cancer variant annotation and prioritization.

Label-Free Comparative Proteomics Analysis Revealed Heat Stress Responsive Mechanism in Hypsizygus marmoreus

Frontiers in Microbiology, 2021
Heat stress is an important adverse environmental stress that influences the growth and development of Hypsizygus marmoreus (white var.). However, the molecular basis of heat stress response in H. marmoreus remains poorly understood. In this study, label-

Revisiting the role of intermittent heat transport towards Reynolds stress anisotropy in convective turbulence [PDF]

Journal of Fluid Mechanics, 2020, 2019
Thermal plumes are the energy containing eddy motions that carry heat and momentum in a convective boundary layer. The detailed understanding of their structure is of fundamental interest for a range of applications, from wall-bounded engineering flows to quantifying surface-atmosphere flux exchanges. We address the aspect of Reynolds stress anisotropy
