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

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)

Light‑Driven Propulsion of Graphene Aerogels in Microgravity
Advanced Science, Volume 13, Issue 33, 15 June 2026.Ultralight graphene aerogels convert laser light into thrust. Parabolic‐flight experiments directly compare their motion in microgravity and at 1 g, revealing order‐of‐magnitude enhancements in distance, velocity, and transient thrust when weight and friction are removed (∼50 times enhancement).

Unstable Weak Imbibition in Fractured Porous Media: Microfluidic and Theoretical Insights
Water Resources Research, Volume 62, Issue 6, June 2026.Abstract Weak imbibition in permeable media is crucial for CO2 geological sequestration, oil and gas extraction, and groundwater contamination and remediation. Previous studies predicted that weak imbibition under favorable viscosity ratios produces stable displacement, but this assumption may fail in fractured porous media.

Heat acclimation improves the neural control of body temperature during heat stress in older adults
The Journal of Physiology, Volume 604, Issue 12, Page 4968-4983, 15 June 2026.Abstract figure legend The neural control of body temperature during heat stress was compared between younger and older adults before and after 7 days of passive heat acclimation (hot water immersion; rectal temperature ≥38.5°C for 1 h). Pre‐acclimation, the onset threshold for increases in skin sympathetic nerve activity, cutaneous vascular ...
