Hypergravity Conditioning on Ileal Movements in Rats

Aviation, Space, and Environmental Medicine, 2012
Stress is a common trigger for various physiological disturbances, including feeding disorders. One of the possible mechanisms for feeding disorders may be linked to changes in intestinal movement caused by stress. Therefore, here we investigated in vitro stress-induced changes in ileal movement.Rats (female Wistar, SPF) were divided into Control (1 G)

Mechanisms of haemoglobin mass expansion following heat stress

The Journal of Physiology, EarlyView.
Abstract figure legend Theorised mechanisms of heat stress‐induced erythropoiesis which may facilitate the expansion of haemoglobin mass. A, acute: heat stress‐induced renal ischaemia. Redistribution of blood flow away from the kidneys to facilitate thermoregulation during heat stress could reduce renal oxygen delivery, subsequently lowering renal PO2${

Pharmacological Stimulation of Type 5 Adenylyl Cyclase Stabilizes Heart Rate Under Both Microgravity and Hypergravity Induced by Parabolic Flight

Journal of Pharmacological Sciences, 2012
We previously demonstrated that type 5 adenylyl cyclase (AC5) functions in autonomic regulation in the heart. Based on that work, we hypothesized that pharmacological modulation of AC5 activity could regulate the autonomic control of the heart rate under

Gravity, a regulation factor in the differentiation of rat bone marrow mesenchymal stem cells

Journal of Biomedical Science, 2009
Background Stem cell therapy has emerged as a potential therapeutic option for tissue engineering and regenerative medicine, but many issues remain to be resolved, such as the amount of seed cells, committed differentiation and the efficiency.

The maturation of regional sweating patterns from childhood to young adulthood in females

Experimental Physiology, Volume 111, Issue 5, Page 2575-2587, 1 May 2026.
Abstract Children are considered heat vulnerable, with the belief that maturation of sweating occurs throughout childhood. Indeed, young children demonstrate distinct patterns of regional sweating compared to adults, but little is known about this pattern maturation throughout puberty. This study aimed to investigate the maturation of regional sweating

Hypergravity-induced malfunction was moderated by the regulation of NMDA receptors in the vestibular nucleus

Scientific Reports, 2021
Gravity alteration is one of the critical environmental factors in the space, causing various abnormal behaviors related with the malfunctioned vestibular system. Due to the high plastic responses in the central vestibular system, the behavioral failures

Recent advances in boosting interfacial bubble dynamics with external fields

Droplet, Volume 5, Issue 2, April 2026.
External physical fields, including acoustic, magnetic, thermal, mechanical, and optical stimuli, accelerate the entire bubble‐dynamics sequence of nucleation, growth, and detachment. Abstract The efficiency of industrial electrocatalytic reactions depends not only on generating gaseous products but also on their detachment from the catalyst surface ...

How hot is too hot for people? A review of empirical models of perceptual, physiological and functional limits of human heat tolerance

Experimental Physiology, Volume 111, Issue 4, Page 1669-1686, 1 April 2026.
Abstract How hot is too hot for people? This is a question that human thermal physiologists are asked often by a variety of knowledge users across the public and private sectors, who have grown aware of the negative impact of global warming on people's health and quality of life.

Dry and humid heat acclimation induces similar adaptations and cross‐acclimation benefits in trained male cyclists

The Journal of Physiology, Volume 604, Issue 7, Page 2757-2777, 1 April 2026.
Abstract figure legend Adaptive responses to hot‐dry and warm‐humid heat acclimation. Abstract This study compared adaptive responses and cross‐acclimation between dry and humid heat acclimation (HA). In a cross‐over design, trained males completed a heat stress test in hot‐dry (Dry‐HST: 42°C, 25% relative humidity [RH]) and warm‐humid (Humid‐HST: 33°C,
