Bio-mechanical effects of femoral neck system versus cannulated screws on treating young patients with Pauwels type III femoral neck fractures: a finite element analysis

BMC Musculoskeletal Disorders
Introduction As a novel internal fixation for femoral neck fractures, the femoral neck system has some advantages for young Pauwels type III femoral neck fractures without clear biomechanical effects and mechanisms. Thus, the objection of the study is to

LPS‐Induced Mitochondrial Damage via SLC41A1‐Mediated Magnesium Ion Efflux Leads to the Pyroptosis of Dental Stem Cells

Advanced Science, EarlyView.
Lipopolysaccharide induces upregulation of the magnesium (Mg2+) efflux transporter solute carrier family 41 member 1 in dental stem cells, leading to a decrease in intracellular Mg2+ concentration and promoting the binding of oligomycin sensitivity‐conferring protein and cyclophilinD.

A Resistive Soft Robotic Exosuit for Dynamic Body Loading in Hypogravity

Advanced Science, EarlyView.
The resistive hypogravity exosuit is a lightweight wearable robotic exosuit that uses pneumatic artificial muscles to restore Earth‐like metabolic and muscular demands during locomotion in low gravity. Tested on healthy subjects in Earth and simulated Moon gravity, the suit restores energy expenditure and muscle activation without altering gait ...
