Abstract: The mechanism(s) underlying photorefractoriness in temperate zone seasonally breeding birds remains undetermined. Our recent findings reveal a link between the upregulation of GABAA receptors (GABAARs) in the premammillary nucleus (PMM) and the state of photorefractoriness.… read more here.

Abstract: Hyperandrogenism with virilisation de novo in postmenopausal women is exceedingly rare, with aetiology oscillating between ovarian tumours, adrenal tumours, ovarian hyperthecosis and, less frequently, Cushing's syndrome. We report a case of a postmenopausal woman in… read more here.

DOI: 10.3389/fnagi.2022.948219
Abstract: Ovarian hormones, particularly 17β-estradiol, are involved in numerous neurophysiological and neurochemical processes, including those subserving cognitive function. Estradiol plays a key role in the neurobiology of aging, in part due to extensive interconnectivity of the… read more here.
