Role of nitric oxide of the median preoptic nucleus (MnPO) in the alterations of salivary flow, arterial pressure and heart rate induced by injection of pilocarpine into the MnPO and intraperitoneally
(Associação Brasileira de Divulgação Científica (ABRADIC), 2003-07-01)
We investigated the effect of L-NAME, a nitric oxide (NO) inhibitor and sodium nitroprusside (SNP), an NO-donating agent, on pilocarpine-induced alterations in salivary flow, mean arterial blood pressure (MAP) and heart ...
Ventromedial hypothalamus lesions increase the dipsogenic responses and reduce the pressor responses to median preoptic area activation
(Elsevier B.V., 1997-08-01)
In this study, we investigated the participation of adrenergic receptors of the median preoptic area (MnPO) and the participation of ventromedial hypothalamus (VMH) in angiotensin II- (ANG II)-induced water intake and ...
Does the median preoptic nucleus contribute to sympathetic hyperactivity in spontaneously hypertensive rats?
(Elsevier B.V., 2016-02-01)
The present study sought to determine the involvement of median preoptic nucleus (MnPO) in the regulation of the cardiovascular function and renal sympathetic activity in normotensive (NT) and spontaneously hypertensive ...
EFFECT OF LATERAL HYPOTHALAMUS LESIONS ON THE WATER AND SALT INTAKE, AND SODIUM AND URINE EXCRETION INDUCED BY ACTIVATION OF THE MEDIAN PREOPTIC NUCLEUS IN CONSCIOUS RATS
(Elsevier B.V., 1995-06-25)
In this-study we investigated the influence of electrolytic lesion of the lateral hypothalamus (LH) on the water and salt appetite, and the natriuretic, diuretic and cardiovascular effects induced by angiotensinergic, ...
Manganese-Oxidizing Antarctic Bacteria (Mn-Oxb) release Reactive Oxygen Species (ROS) as secondary Mn(II) oxidation mechanisms to avoid toxicity
(MDPI, 2021)
Manganese (Mn)-oxidizing bacteria (MnOxb) are an essential group of microorganisms that oxidize soluble Mn(II) to form precipitate Mn(III) minerals, playing a crucial role in soil formation. The Fildes Peninsula is one of ...
Involvement of the median preoptic nucleus in blood pressure control
(Elsevier B.V., 2014-01-13)
Studies have demonstrated that median preoptic nucleus (MnPO) neurons play a role in organizing the cardiovascular responses induced by changes in the circulating blood volume. The present study examined whether the MnPO ...
Median preoptic nucleus excitatory neurotransmitters in the maintenance of hypertensive state
(Elsevier B.V., 2018-09-01)
The crucial role of the median preoptic nucleus (MnPO) in the maintenance of hydroelectrolytic balance and autonomic regulation have been highlighted. Recently, the participation of the MnPO in the control of sympathetic ...
Ibotenate lesion of the medial hypothalamus alters the salt intake and pressor responses to activation of the median preoptic nucleus in rats
(Elsevier B.V., 1997-02-01)
We investigated the influence of ibotenic acid lesions of the medial hypothalamus (MH) on salt appetite and arterial blood pressure responses induced by angiotensinergic and adrenergic stimulation of the median preoptic ...
L-Type calcium channels mediate water intake induced by angiotensin injection into median preoptic nucleus
(Elsevier B.V., 2006-04-01)
Calcium ions are widely accepted as critically important in responses of neurons to a stimulus. We have show previously the central involvement of angiotensin II (ANGII) in water intake. This study determined whether ...
Optical and structural properties of Mn2+ doped PbGeO3-SbPO4 glasses and glass-ceramics
(Elsevier B.V., 2016-01-01)
This paper shows the study of optical and structural properties of SbPO4-PbGeO3-MnCl2 glass and glass-ceramics. Glass was prepared by melting-quenching methodology while the glass ceramic was obtained by controlled thermal ...
