This research aimed to study the changes in platelet function and their underlying mechanisms iron deficiency anemia. Initially, we evaluated an IDA mice model. Due inability accurately reduce intracellular Fe2+ concentrations, investigated impact of on by introducing varying concentrations Fe2+. To probe mechanism, simultaneously examined dynamics calcium cytosol, integrin αIIbβ3 activation Fe2+-treated platelets. Ferroptosis inhibitors Lip-1 Fer-1 were applied determine whether ferroptosis...

Researches on hypersonic vehicles have been a hotspot in the field of aerospace because pursuits for higher speed by human being. Infrared imaging guidance is playing very important role modern warfare. When an Ray(IR) guided missile flying air at high speed, its optical dome suffers from serious aero-optic effects flow. The turbulence around and thermal window would cause disturbance to wavefront target. Therefore, detected images will be biased, dithered blurred, capabilities seeker...
