Scaffold design considerations for peripheral nerve regeneration.

Peripheral nerve injury (PNI) represents a serious clinical and public health problem due to its high incurrence and poor spontaneous recovery. Compared to autograft, which is still the best current practice for long-gap peripheral nerve defects in clinics, the use of polymer-based biodegradable nerve guidance conduits (NGCs) has been gaining momentum as an alternative to guide the repair of severe PNI without the need of secondary surgery and donor nerve tissue. However, simple hollow cylindrical tubes can barely outperform autograft in terms of the regenerative efficiency especially in critical sized PNI.

A Pilot Evaluation of the Respect You Curriculum.

Background: The objective of this study is to evaluate the Respect YOU program's impact on students' eating expectancies, body image satisfaction levels, self-efficacy, and knowledge. A total of 444 (intervention cohort n = 348, control cohort n = 96) underclassmen enrolled in health or physical education courses from 7 high schools in the Midwest participated in the study.

Methods: A repeated measure research design was utilized to assess students' eating expectancies, body image satisfaction levels, self-efficacy, and knowledge.
