Purpose: Mandibular repositioning devices (MRDs) are an effective treatment option for obstructive sleep apnea syndrome (OSAS), particularly in patients who refuse or cannot tolerate continuous positive airway pressure (CPAP). However, sex differences in the response to therapy and predictors of response are not clearly defined. This analysis of data from the long-term prospective ORCADES trial compared MRD efficacy in men and women with OSAS.

We attempted transplantation of adult neural stem cells (ANSCs) inside an autologous venous graft following surgical transsection of nervis cruralis with 30 mm long gap in adult pig. The transplanted cell suspension was a primary culture of neurospheres from adult pig subventricular zone (SVZ) which had been labeled in vitro with BrdU or lentivirally transferred fluorescent protein. Lesion-induced loss of leg extension on the thigh became definitive in controls but was reversed by 45-90 days after neurosphere-filled vein grafting.

In order to improve cell therapy techniques, we have characterized a multipotent neural precursor cell isolation technique from the subventricular zone of adult pig brain. The pig is a non-primate species that is immunologically closest to human. The proliferative zone of this neurogenic structure was first localized in situ in the pig brain by Ki-67 immunohistochemistry, as a ventral subfield of the Nissl-stained subventricular zone.
