The contact force between lunar-based equipment and lunar soil.

Lunar-based equipment plays a vital role in the exploration of the moon because it undertakes the tasks of moving, transporting, digging, and so on. In order to control the gait of lunar-based equipment more precisely and guarantee mobile stability, the contact mechanism between its foot and lunar soil is worthy of in-depth study. In this paper, a contact model is proposed to predict the stress, strain, and displacement both on the contact surface and in the lunar soil when the foot is under vertical load.

Anti-diabetic effect of Jacq. polysaccharides via the PI3K/Akt/GSK-3β signaling pathway and regulation of gut microbiota.

This study evaluated the anti-diabetic effect of polysaccharides isolated from and their underlying mechanisms. To achieve this, a type 2 diabetes mellitus mouse model was established using a combination of a high-fat diet and low-dose streptozotocin injection. The mice were treated with polysaccharides (OCPs) for 4 weeks.

Reduced lung water transport rate associated with downregulation of aquaporin-1 and aquaporin-5 in aged mice.

1. The purpose of the present study was to examine lung water transport properties and the expression and regulation of the alveolar endothelial water channel aquaporin (AQP)-1 and the epithelial water channel AQP-5 in aged mouse lung using gene expression analysis and water permeability measurements. 2.
