Physiologic Long Head Biceps Tendon Excursion Throughout Shoulder Range of Motion: A Cadaveric Study.
TL;DR: Evaluating the normal excursion of LHBT that occurs through a glenohumeral range of motion found that shoulder positioning is an important consideration in establishing a normal length-tension relationship during biceps tenodesis and elbow position does not significantly affect LHBT excursion.

TL;DR: It is suggested that North American pumas show a near identical quantity of genomic depletion as African cheetahs, suggesting they were also extirpated form North America during the quaternary mammal extinction and repopulated from South America subsequently, and the fossil record puts the oldest cheetah fossils in Asia 3 million years before present.

TL;DR: This study inspected a NPC-associated region on the short arm of chromosome 4 previously implicated by a genome-wide linkage analysis of familial NPC and could not affirm the genetic association within this region with NPC, but provide an opportunity for further gene discovery in this highly endemic NPC population.
