Prediabetic cardiomyopathy is attenuated by hypothalamic PVN oxytocin neuron activation

The Journal of Physiology, EarlyView.
Abstract figure legend A long‐term high‐fat, high‐fructose diet induces prediabetes with insulin resistance, hyperinsulinaemia, elevated triglycerides and metabolic‐associated steatotic liver disease (MASLD) in male rats. Animals developed prediabetic cardiomyopathy characterized by diastolic dysfunction, interstitial fibrosis and tachycardia ...

Effect of area ratio of the primary nozzle on steam ejector performance considering nonequilibrium condensations

, 2021
The formation and evaporation of nanodroplets in steam ejectors is neglected in many numerical simulations. We analyse the influence of a primary nozzle on steam ejector performances considering phase change processes. The numerical model is validated in

Pressurized Solid Oxide Electrolysis—Operational Strategies

Fuel Cells, Volume 26, Issue 2, April 2026.
ABSTRACT Pressurized high‐temperature electrolysis is a promising pathway for high‐efficiency hydrogen production that enables direct compression and heat recovery opportunities not accessible to low‐temperature electrolysis. While laboratory testing is routinely conducted near atmospheric pressure, there is increasing interest in commercial deployment
