Primary stability of cementless threaded acetabular cups at first implantation and in the case of revision regarding micromotions as indicators [PDF]

, 2012
The primary stability of cementless total hip endoprosthesis is of vital importance for proximate, long-term osteointegration. The extent of micromotions between implant and acetabulum is an indicator of primary stability.

Parvalbumin Interneuron‐Dependent Hippocampal Neurogenesis Evoked by Prolonged Rhythmic Light Flicker

Advanced Science, EarlyView.
This study demonstrates that prolonged rhythmic 40 Hz light flicker enhances spatial learning by stimulating PV interneuron‐dependent neurogenesis. The light flicker selectively activates PV interneurons, which enhances GABAergic support for the integration of immature neurons in the adult dentate gyrus.

A Novel Cranial Bone Transport Technique Repairs Skull Defect and Minimizes Brain Injury Outcome in Traumatic Brain Injury Rats

Advanced Science, EarlyView.
This study introduces a novel, safe, and effective surgical technique: Cranial bone transport (CBT) to improve traumatic brain injury (TBI) outcomes in rats. CBT significantly accelerated skull defect bone repair in addition to its promoting effects on neurological function recovery. This work provides an alternative therapy for patients suffering from
