yohimbine/fatigue

Recent advances in neurobiology have aided our understanding of attention-deficit hyperactivity disorder (ADHD). The higher-order association cortices in the temporal and parietal lobes and prefrontal cortex (PFC) interconnect to mediate aspects of attention. The parietal association cortices are

OBJECTIVE The unusual side effect of priapism associated with the antidepressant trazodone has led researchers to evaluate its use for the treatment of erectile dysfunction. Previous studies have shown nearly 70% efficacy in patients. Unfortunately, these studies have been anecdotal, retrospective

The present investigation was undertaken to study the nature of neuro-melanophore junction in the white-spotted rabbit fish Siganus canaliculatus. In vitro experiments using split fin preparation indicated that melanophores of S. canaliculatus are highly responsive to potassium ions and adrenergic

BACKGROUND Exogenous catecholamine administration in humans stimulates ventilation. The present study was designed to investigate whether increased endogenous catecholamine release influences objective measures of ventilation and subjective measures of breathlessness in normal

The effects of intravenous infusion of the nonselective alpha-adrenergic antagonist phentolamine or of the selective alpha 2-adrenergic antagonist yohimbine on growth hormone (GH), prolactin (PRL) and cortisol secretion during insulin-induced hypoglycemia were studied in 11 healthy young men. The GH
