Climate change and temperature dependent biogeography: oxygen limitation of thermal tolerance in animals [PDF]

, 2001
Recent years have shown a rise in mean global temperatures and a shift in the geographical distribution of ectothermic animals. For a cause and effect analysis the present paper discusses those physiological processes limiting thermal tolerance.

An efficient strategy for producing RNA‐free Nucleocapsid protein of SARS‐CoV‐2 for biochemical and structural investigations

FEBS Open Bio, EarlyView.
Cleavable N‐terminal Thioredoxin fusion enabled soluble expression and purification of otherwise insoluble SARS‐CoV‐2 Nucleocapsid (N) protein. A four‐step purification strategy yielded highly homogeneous, RNA‐free N protein. Binding assays showed high RNA affinity (Kd ~ 28 nm). The study will facilitate high‐resolution structural studies of N protein,

Polydatin ameliorates ovalbumin‐induced asthma in a rat model through NCOA4‐mediated ferroautophagy and ferroptosis pathway

FEBS Open Bio, EarlyView.
In this research, a rat model of asthma was created using OVA, and polydatin served as an intervention. By inhibiting ferroautophagy mediated by NCOA4 and averting ferroptosis, polydatin has been demonstrated to reduce asthma. This work presents new ideas for investigating the mechanism of polydatin's ability to alleviate asthma, in addition to ...

Female thermal sensitivity and behaviour across the lifespan: A unique journey

Experimental Physiology
Women are a group of individuals that undergo unique anatomical, physiological and hormonal changes across the lifespan. For example, consider the impact of the menstrual cycle, pregnancy and menopause, all of which are accompanied by both short‐ and ...

Amino Acid‐Sensing Neurons in the Anterior Piriform Cortex Control Brown Adipose Tissue Thermogenesis

Advanced Science
Amino acid sensing in the central nervous system plays a key role in regulating energy homeostasis. The anterior piriform cortex (APC) has been implicated in sensing amino acid deficiency and rapidly inducing an aversive response.

Downregulation of sST2, a decoy receptor for interleukin‐33, enhances subcutaneous tumor growth in murine pancreatic cancer cells

FEBS Open Bio, EarlyView.
Subcutaneous implantation of murine Panc02 pancreatic cancer cells depleted of sST2, a soluble decoy receptor for the proinflammatory interleukin‐33 (IL‐33), leads to a decreased number of GLUT4‐positive cancer‐associated adipocytes, reduced levels of the anti‐inflammatory molecule adiponectin, increased phosphorylation of IκBα, elevated Cxcl3 ...

Clothing and Regulation of Body Temperature

Journal of the Anthropological Society of Nippon, 1978
The scientific study of clothing principles may be said to date from about 1930 in Japan, and from about the beginning of the World War II in United States of America. In Japan it was found that when a man wearing a suitable clothing for the season was in a comfortable state, air temperature was about 32°Cand air humidity was about 50% between skin ...

Transcriptional regulation of neuropeptide receptors underlies context‐dependent adaptation in Drosophila melanogaster

FEBS Open Bio, EarlyView.
Under environmental changes, the expression level of neuropeptide (NP) and neuropeptide receptor (NPR) genes changes to confer context‐dependent adaptation to the model organism Drosophila melanogaster. Through finding more regulatory elements in the NPR genes in comparison with their ligands (NPs), we found that NPR‐biased transcriptional regulation ...

A Theory of Social Thermoregulation in Human Primates

Frontiers in Psychology, 2015
Beyond breathing, the regulation of body temperature—thermoregulation—is one of the most pressing concerns for many animals. A dysregulated body temperature has dire consequences for survival and development.
