Isolating the Direct Effects of Growth Hormone on Lifespan and Metabolism.

Prior studies show that disrupting somatotropic axis components extends laboratory mouse lifespan, but confounding effects of additional genes and hormones obscure the specific impact of growth hormone (GH) on longevity. We address this issue by using mice with a specific knockout of the GH gene, revealing that disrupting GH alone substantially increases lifespan. The longevity effects are accompanied by altered metabolic fuel utilization, directly linking GH action to aging mechanisms.

Lateral Heterostructures Fabricated via Artificial Pressure Gradient.

Hydrostatic conditions are generally pursued in high-pressure research, maintained to prevent the intrinsic pressure gradient on the culets of diamond anvil cells (DACs) from introducing heterogeneity to the structure and physical properties of the regulated materials. Here, a pioneering route to fabricate lateral heterostructures is proposed via artificial pressure gradients intentionally designed in DACs. Under the tailored pressure gradients, different structural phases emerge in distinct parts of the material, resulting in the formation of heterostructures.

Inhibition of the NLRP3/caspase-1 cascade related pyroptosis relieved propofol-induced neuroinflammation and cognitive impairment in developing rats.

Background: Numerous preclinical studies have demonstrated that prolonged exposure to propofol (A general anaesthetics) can lead to hippocampus injury in immature brains and impact long-term learning and memory functions. Neuroinflammation plays a pivotal role in the impairment of brain function associated with early exposure to anesthetic drugs. Nevertheless, the involvement of hippocampal pyroptosis and neuroinflammation mediated by the NLRP3/caspase-1 signaling cascade in propofol-induced developmental neurotoxicity remains unclear.

Propensity score matching-based analysis of the effect of corticosteroids in treating severe drug-induced liver injury.

Background And Aim: There is no conventional treatment for patients with severe drug-induced liver injury (DILI) except for discontinuation of liver injury drugs and symptomatic supportive therapy. Opinions on whether corticosteroids can be used to treat severe DILI are conflicting, and most of the relevant clinical studies are case reports or retrospective studies, which still need to be supported by high-level evidence-based medical studies. This study aimed to evaluate the effect and tolerance of corticosteroids in patients with severe DILI.
