abstract background: “polycystic ovary syndrome (pcos) is a complex endocrine and metabolic disorder associated with ovulatory dysfunction”. “autonomic and central nervous systems play important roles in the regulation of ovarian physiology”. the noradrenergic nucleus locus coeruleus (lc) plays a central role in the regulation of the sympathetic nervous system and synaptically connected to the ...

exposure to stress leads to physiological changes called “stress response” which are the result of the changes in the adrenomedullary hormone system, hypothalamus-pituitary-adrenal (hpa) and sympathetic nervous system (sns) activity. in the present study, the effects of chronic physical and psychological stress and also the role of sympathetic system effects in stress on ischemia/reperfusion (i...

objective: the present study aimed to determine whether castration altered osmotically stimulated vasopressin (vp) release and urinary volume and what is the role of endocrine-stress axis in this process. materials and methods: totally 108 mice were studied in two main groups of castrated (n=78) and control (n=30). each group was extracted by acute cold stress (4◦c for 2h/day), restraint stress...

Background: Uterine natural killer (uNK) cells are the most abundant leukocytes in pre-implantation endometrium and early pregnancy deciduas in humans and rodents. They are associated with structural changes in maternal spiral arteries but regulation of their re-cruitment and activation is incompletely understood. The major subpopulation of uNK cells in humans expresses CD56, the neural cell ad...

the basis of acupuncture is still being studied from many different aspects. some preliminary views include: 1) the analgesic function of acupuncture derives from the clashing of the biochemical lines of acupuncture and those of the pain stimulus in the transmitting processes of the central nervous system, the former overriding the latter. 2) acupuncture strengthens the cerebral cortex's i...
