A feature of stability diagrams of liquid bridges between unequal disks subjected to small axial gravity forces is that, for each separation of disks, there is a value of microgravity for which an absolute minimum volume limit is reached. The dependence of such microgravity values on the liquid bridge geometry has been experimentally checked by using the neutral buoyancy technique, experimental...

Endothelial nitric oxide contributes to the vascular hyporesponsiveness to norepinephrine (NE) observed in carotid arteries from rats exposed to simulated microgravity. The goal of the present study was to determine whether a cyclooxygenase product of arachidonic acid also influences vascular responsiveness in this setting. Microgravity was simulated in rats by hindlimb unweighting (HU). After ...

This study aimed to assess the effects of simulated microgravity (SMG) on senescent human fibroblasts (HFs). The HFs were treated with 150 µM H2O2 in a culture medium for 90 minutes induction. induced SMG 72 hours by Gravity simulator, while control group was same CO2 incubator. Cell morphology analysis showed that condition retrieved fibroblastic from senescence. WST1 assay and cell counting i...
