The Vicious Cycle of Sleep Disruption and Inflammaging: Mechanisms, Consequences, and Therapeutic Opportunities. [PDF]
Aging CellSleep disruption and circadian decline drive inflammaging and immune aging via the gut‐brain axis, NLRP3, and TLR4, forming a vicious cycle that accelerates cognitive decline and epigenetic aging. Targeting this sleep‐immune axis offers a viable strategy for promoting healthy longevity. ABSTRACT Aging is characterized by two interdependent hallmarks: a

Multidirectional Forging Simulation Research on a Tee Joint Valve [PDF]
Advances in Physics Research, 2014 A numerical tee joint valve model was set up in this paper. The numerical forming simulation was implemented. The load of the upper punch was predicted. The final temperature field shows that varying temperatures are within the feasible forging temperature region. The results from the numerical simulation were verified through the practical experiment.
