The gut-brain axis and sodium appetite: can inflammation-related signaling infl...

Cardiovascular responses to L-glutamate microinjection into the NTS are abrogat...

Redox imbalance in regions of the CNS controlling blood pressure is increasingly recognized as a leading factor for hypertension. Nucleus tractus solitarius (NTS) of the dorsomedial medulla is the main region receiving excitatory visceral sensory inputs that modulate autonomic efferent drive to the cardiovascular system. This study sought to determine the capacity of reduced glutathione, a major bioactive antio...

Inhibition of central angiotensin II-induced pressor responses by hydrogen pero...

Hydrogen peroxide (H2O2), important reactive oxygen species produced endogenously, may have different physiological actions. The superoxide anion (O2 •_) is suggested to be part of the signaling mechanisms activated by angiotensin II (ANG II) and central virus-mediated overexpression of the enzyme superoxide dismutase (that dismutates O2 •_ to H2O2) reduces pressor and dipsogenic responses to central ANG II. Wh...

Cardiovascular responses produced by central injection of hydrogen peroxide in ...

Reactive oxygen species (ROS) have been shown to modulate neuronal synaptic transmission and may play a role on the autonomic control of the cardiovascular system. In this study we investigated the effects produced by hydrogen peroxide (H2O2) injected alone or combined with the anti-oxidant agent N-acetil-l-cysteine (NAC) or catalase into the fourth brain ventricle (4th V) on mean arterial pressure and heart ra...

Central antioxidant therapy inhibits parasympathetic baroreflex control in cons...

Baroreceptor reflex is an important system for neural control of blood pressure. Recently, reactive oxygen species (ROS) have been shown to play an important role in neuronal activity of central areas related to blood pressure control. The aim of this study was to investigate the effects elicited by ascorbic acid (AAC) and N-acetylcysteine (NAC) injections into the 4thV on the parasympathetic component of the b...

Chemoreflex control of the cardiovascular system remains altered after recovery...

This study aimed to evaluate the cardiovascular component of the arterial chemoreflex in rats recovered from low protein diet. Male Fischer rats were randomly divided into control and recovered (R-PR) groups after weaning. R-PR rats were fed with low protein diet for 35 days and recovered under normal protein diet for 70 days. Control rats received normal protein diet for 105 days. Arterial chemoreflexwas elici...
