Cyhalothrin increased c-fos immunoreactivity at the paraventricular nucleus of the hypothalamus in rats, and supressed macrophage activity in an adrenal-dependent fashion
(Amsterdam, 2009)
Synthetic type II pyrethroid insecticides, such as cyhalothrin at certain dosage levels, simultaneously induce stress-like symptoms and innate immunosuppressive effects in laboratory animals. The present study was designed ...
Nitrergic neurotransmission in the paraventricular nucleus of the hypothalamus modulates autonomic, neuroendocrine and behavioral responses to acute restraint stress in rats
(2019-03-02)
We investigated the involvement of nitrergic neurotransmission within the paraventricular nucleus of the hypothalamus (PVN) in modulation of local neuronal activation, autonomic and neuroendocrine responses and behavioral ...
Inhibition of nNOS in the paraventricular nucleus of hypothalamus decreases exercise-induced hyperthermia
(2021-12-01)
The paraventricular nucleus of the hypothalamus (PVN) is an important site for autonomic control, which integrates thermoregulation centers and sympathetic outflow to thermoeffector organs. PVN neurons express the neuronal ...
Cold-induced glutamate release in vivo from the magnocellular region of the paraventricular nucleus is involved in ovarian sympathetic activation
(2010)
We previously reported that centrally-induced sympathetic activation in response to cold stress is associated with a polycystic ovarian condition in rats, and thyrotrophin-releasing hormone (TRH) released locally from the ...
Cyhalothrin increased c-fos immunoreactivity at the paraventricular nucleus of the hypothalamus in rats, and suppressed macrophage activity in an adrenal-dependent fashion
(ELSEVIER SCIENCE BV, 2009)
Synthetic type II pyrethroid insecticides, such as cyhalothrin at certain dosage levels, simultaneously induce stress-like symptoms and innate immunosuppressive effects in laboratory animals. The present study was designed ...
Modulatory role of locus coeruleus and estradiol on the stress response of female rats
(HUMANA PRESS INC, 2009)
The activity of the hypothalamic-pituitary-adrenal axis is modulated by the norepinephrinergic system and, in females, also by the ovarian hormones. We investigated the role of ovarian steroids and the locus coeruleus (LC) ...
Neonatal maternal separation opposes the facilitatory effect of castration on the respiratory response to hypercapnia of the adult male rat: Evidence for the involvement of the medial amygdala
(Wiley-Blackwell, 2017-12-01)
Respiratory manifestations of panic disorder (PD) include a greater respiratory instability and enhanced responsiveness to CO2 compared to normal individuals. Although the prevalence of PD is approximately three times ...
The role of oxidative stress in renovascular hypertension
(Wiley-Blackwell, 2011-02-01)
P>1. There is mounting evidence that increased oxidative stress and sympathetic nerve activity play important roles in renovascular hypertension. in the present review, we focus on the importance of oxidative stress in two ...
Investigation of the hypothalamic defensive system in the mouse
(Elsevier B.V., 2008-10-10)
The hypothalamus plays especially important roles in various endocrine, autonomic, and behavioral responses that guarantee the survival of both the individual and the species. In the rat, a distinct hypothalamic defensive ...
