Tyrosine is the precursor for catecholamine neurotransmitters. When catecholamine-containing neurons are physiologically active (as sympathoadrenal cells are in hypotension), tyrosine administration increases catecholamine synthesis and release. Since hypotension can alter plasma amino acid
The expression of c-Fos defines brain regions activated by the stressors hypotension and glucoprivation however, whether this identifies all brain sites involved is unknown. Furthermore, the neurochemicals that delineate these regions, or are utilized in them when responding to these stressors
The aim of the present work was to determine if noradrenergic neurons of the anterior and the posterior subregions of the locus coeruleus exhibit a difference in reactivity in response to sodium nitroprusside-induced arterial hypotension, and if the pharmacological induction of tyrosine hydroxylase
Neurotensin (NT) exerts its analgesic effects through activation of the G protein-coupled receptors NTS1 and NTS2. This opioid-independent antinociception represents a potential alternative for pain management. While activation of NTS1 also induces a drop in blood pressure and body temperature, NTS2
Identification of neurons, and their phenotype, that are activated in response to specific stimuli is a critical step in understanding how neural networks integrate inputs to produce specific outputs. Here, we developed novel mouse monoclonal antibodies of different IgG isotypes that are specific to
Alpha 2-adrenergic receptor changes during antidepressant treatment were studied using 3H-yohimbine binding to human platelet membranes and clonidine-induced hypotension. Twenty-six patients with major depressive disorder (MDD) participated for 4-6 weeks in a trial of imipramine (2.5 mg/kg/day),
Neural networks that mediate the reflex response to baroreceptor withdrawal were explored in Sus scrofa. Induction of c-fos was used as a monitor of synaptic activity in response to hypotension sustained by systemic administration of a peripheral vasodilator, sodium nitroprusside. Patterns of c-fos
Although tyrosine kinase inhibitors (TKI) are the most common first-line therapy for metastatic renal cell carcinoma, high-dose interleukin-2 (HD-IL2) remains the only agent that provides durable complete responses. The optimal sequence of these agents remains uncertain. This retrospective
OBJECTIVE
To describe a case of spontaneous intracranial hypotension with a previously unreported constellation of presenting features.
METHODS
Case report.
METHODS
Tertiary care center.
RESULTS
We describe a patient with intracranial hypotension who presented with a parkinsonian syndrome and later
We have previously demonstrated that the activation of the spleen tyrosine kinase (Syk)/inhibitory-κB (IκB)-α/nuclear factor-κB (NF-κB) p65 signalling pathway contributes to hypotension and inflammatory response in a rat models of zymosan (ZYM)-induced non-septic shock. The purpose of this study was
Our current knowledge of the sites of action of the centrally-acting antihypertensive drug clonidine is based almost entirely on experiments in anesthetized animals. The aim of this study was to determine, in conscious rabbits, the sites of action in the brainstem of systemically administered
