Gear-Related Stress Analysis and Comparison Between the Fem and Agma Standards
Abstract: In many different devices, gears enable the efficient transfer of motion and torque. They are an essential component of modern mechanical power transmission systems. It has been demonstrated that bending and surface contact stresses at the gear tooth are the primary causes of gear failure, despite their widespread use. Too much stress can lead to tooth wear, pitting, or breakage, which can ultimately reduce the operating life and reliability of …

Hematopoietic stem progenitor cells reduce the proliferation of Tregs via regulation of IL-12/STAT4 signaling during chronic stress
Abstract: Abstract. Physical or psychological chronic stress mediates the impaired immune response by inducing the proliferation of regulatory T cells (Tregs). Our recent studies showed that hematopoietic stem progenitor cells (HSPCs) significantly modulated the immune system. HSPCs prevented stress-induced lymphocyte apoptosis, exerting a protective effect in chronic stress-induced immune responses. Thus, whether HSPCs could prevent the proliferation of Tregs in conditions of chronic stress was assessed in the present study. Injection …
