Insights into two-phase flow dynamics in closed-loop pulsating heat pipes utilizing FeO/water: experimental visualization study.

This article discusses a focused study on visualizing the flow patterns in a two-phase pulsating heat pipe (PHP) using FeO/water as the working fluid at 3 V/V% concentration. The research also aims to meticulously examine phase change phenomena in the heating section, particularly focusing on bubble formation and expansion processes. A high-speed video camera was utilized to capture dynamic insights into the behavior of the FeO/water mixture.

Influence of apocynin on cardiac remodeling in rats with streptozotocin-induced diabetes mellitus.

Background: Increased reactive oxygen species (ROS) generation in diabetes mellitus (DM) is an important mechanism leading to diabetic cardiomyopathy. Apocynin, a drug isolated from the herb Picrorhiza kurroa, is considered an antioxidant agent by inhibiting NADPH oxidase activity and improving ROS scavenging. This study analyzed the influence of apocynin on cardiac remodeling in diabetic rats.
