Inhibition of Microglial TRPV1 Ameliorates Brain Injury After Intracerebral Hemorrhage by Suppressing AMPK/PINK1-Mediated Mitophagy. [PDF]
CNS Neurosci TherAfter intracerebral hemorrhage, microglial TRPV1 channel opening increases intracellular calcium, triggering excessive AMPK‐PINK1‐mediated mitophagy. This causes microglial dysfunction, neuronal necrosis/apoptosis, blood–brain barrier disruption, and neurological impairment.

Adaptive entry guidance for the Tianwen-1 mission [PDF]
Astrodynamics, 2022 AbstractTo meet the requirements of the Tianwen-1 mission, adaptive entry guidance for entry vehicles, with low lift-to-drag ratios, limited control authority, and large initial state bias, was presented. Typically, the entry guidance law is divided into four distinct phases: trim angle-of-attack phase, range control phase, heading alignment phase, and

Combined application of block and modulation factors to reduce the volume of the low dose area in helical tomotherapy plans for lung cancer. [PDF]
J Appl Clin Med PhysAbstract Background The helical tomotherapy (HT) system can expose more normal lung tissue to low radiation doses, resulting in extensive low‐dose distribution in both lungs which may induce radiation pneumonitis (RP). Purpose This study aims to optimize dosimetric parameters and identify a clinically feasible treatment plan by analyzing the impact of ...
