A meta-analysis of case studies and clinical characteristics of hypertrophic olivary degeneration secondary to brainstem infarction.

Transsynaptic degeneration in the cerebellum and brainstem may give rise to a rare neurological condition with various clinical manifestations, namely hypertrophic olivary degeneration. The classical manifestations of hypertrophic olivary degeneration comprise myoclonus, palatal tremor, ataxia, and ocular symptoms. Any lesions interrupting the dentate-rubro-olivary pathway, referred to as the anatomic Guillain-Mollaret triangle, contribute to the broad aetiologies of hypertrophic olivary degeneration.

Dihydrotestosterone modulates endothelial progenitor cell function via RhoA/ROCK pathway.

Background: Previous findings indicate that testosterone level is negatively correlated with the incidence and mortality of cardiovascular diseases in men. Endothelial progenitor cells (EPCs) play a critical role in endothelial healing and vascular integrity. This study aimed to examine the effects of dihydrotestosterone (DHT), an active metabolite of testosterone, on human EPC function and investigate the underlying mechanism.
