Hemofiltration system for the post traumatic treatment of hyperkalemia in austere conditions.

Background: Hyperkalemia, the buildup of serum potassium to levels >6 mEq L, has been a recognized complication of combat injuries such as acute kidney injury since World War II. Currently, renal replacement therapy (RRT) serves as the standard of care for hyperkalemic patients who fail to respond to medical management. However, RRT is difficult to administer in combat settings, and the time between evacuation and RRT is critical in preventing post-traumatic hyperkalemia.

Fluidic shear stress alters clathrin dynamics and vesicle formation in endothelial cells.

Endothelial cells (ECs) experience a variety of highly dynamic mechanical stresses. Among others, cyclic stretch and increased plasma membrane tension inhibit clathrin-mediated endocytosis (CME) in non-ECs. It remains elusive how ECs maintain CME in these biophysically unfavorable conditions.
