background: stimulants addition and abuse can cause some functional and morphological changes in the normal function of glands and hormones. methamphetamine as an addictive stimulant drug affects the hypothalamic-pituitary-adrenal (hpa) axis and consequently makes some changes in the psychological state of the drug users. the present study aims to examine the relationship between plasma levels ...

introduction rapid-onset obesity with hypoventilation, hypothalamic dysfunction, and autonomic dysregulation (rohhad) is a rare disease. to date, there have been only few reported cases of rohhad syndrome. conclusions only a few case reports have described rohhad syndrome, and it is therefore difficult to manage. in children with rapid and early-onset obesity associated with hypothalamic-pituit...

The role of the ventromedial nuclei of the hypothalamus (VMN) in food behavior was studied in adult male rats, allocated in 3 groups: control, sham and lesioned. Electrolytic lesions were induced stereotaxically (1.2 mA, 15 sec). Results revealed a significant decrease (p<O.05) in body weight (BW) and food intake (FI) in the order of lesioned <sham <control during the fIrst week. However, ...

Kisspeptin is a peptide expressed mainly in the infundibular nucleus of hypothalamus. plays crucial role regulation reproductive functions. It regarded as most important factor responsible for control hypothalamic–pituitary–gonadal axis, onset puberty, and menstruation fertility. activity influences numerous processes such steroidogenesis, follicular maturation, ovulation, ovarian senescence. T...

The hypothalamic paraventricular nucleus (PVN) expresses multiple neuropeptides and plays an essential role in several physiological processes. Among the brain areas directly projecting to PVN are deep structures closely related instinctive behavior. Moreover, neurons can project abundant axons downstream regions key components of stress response. Accordingly, malfunction is implicated stress-r...

OBJECTIVE The fuel sensor AMP-activated protein kinase (AMPK) in the hypothalamus regulates energy homeostasis by sensing nutritional and hormonal signals. However, the role of hypothalamic AMPK in glucose production regulation remains to be elucidated. We hypothesize that bidirectional changes in hypothalamic AMPK activity alter glucose production. RESEARCH DESIGN AND METHODS To introduce bi...
