Noradrenergic A2 neurons in nucleus tractus solitarius (NTS) respond to stressors such as hypoxia. We hypothesize that tyrosine hydroxylase (TH) knockdown in NTS reduces cardiovascular responses to chronic intermittent hypoxia (CIH), a model of the arterial hypoxemia observed during sleep apnea in
Atherosclerosis is initiated by adhesion and infiltration of inflammatory leukocytes into the intima, where non-receptor protein tyrosine kinases, such as focal adhesion kinase (FAK) and proline-rich tyrosine kinase 2 (PYK2), play important roles as intracellular messengers of mechanical and
Despite advances in the understanding of monogenic hypertensive disorders, the genetic contribution to essential hypertension has yet to be elucidated. The position of tyrosine hydroxylase (TH) as the rate-limiting enzyme in catecholamine biosynthesis renders it a candidate gene for the etiology of
Systemic biochemical indexes of sympathetic nerve functionplasma catecholamine concentrations and serum dopamine-beta-hydroxylase activitywere correlated with regional indexesnorepinephrine concentration activities of norepinephrine biosynthetic enzymes in the vas deferensānd with blood pressures
Preterm-born individuals have elevated blood pressure. We tested the hypothesis that this associates with an enhanced antiangiogenic circulating profile and that this association is mediated by variations in capillary density. We studied 204 adults aged 25 years (range, 20-30 years), of which 102
Placental overproduction of anti-angiogenic soluble fms-like tyrosine kinase-1 (sFlt-1) and soluble endoglin (sEng) has a key role in the development of preeclampsia (PE). Circulating endothelin-1 (ET-1) levels are also elevated in PE. In this study, we investigated the correlation between ET-1 and
The present study was conducted to determine whether Valyl-Tyrosine (VY) has an antihypertensive effect on high-normal blood pressure and mild essential hypertension, as well as spontaneous hypertensive rats (SHR). A randomised double-blind placebo-controlled study was carried out on 29 volunteers.
We report here a rare case of atypical posterior reversible encephalopathy syndrome (PRES) due to oral tyrosine kinase inhibitor cabozantinib. No case reports of such have been found in our literature search. The patient, a 70-year-old female with metastatic renal cell cancer on oral tyrosine kinase
OBJECTIVE
This phase III, 52-week study compared fostamatinib with placebo (for 24 weeks) in patients with active rheumatoid arthritis (RA) and an inadequate response to methotrexate (MTX) therapy.
METHODS
Patients taking MTX were randomized (1:1:1) to receive fostamatinib 100 mg twice daily for 52
It remains unclear what roles placenta-originated angiogenic factors play in the pathogenesis of preeclampsia among hypertensive women. We compared maternal soluble fms-like tyrosine kinase 1 (sFlt-1) and placental growth factor (PlGF) levels throughout pregnancy in women with normal
Pro-opiomelanocortin (POMC) synthesized in the anterior (AL) and intermediate lobe (IL) of the rat pituitary gland, is a prohormone precursor of several peptide hormones that may participate in the regulation of blood pressure. We therefore studied the biosynthesis of POMC by measuring the
Patients with chronic intermittent hypoxia (IH) caused by recurrent apneas have a greatly increased risk for developing hypertension, myocardial infarctions, and stroke. The purpose of this article is to highlight some of the recent studies focusing on the mechanisms associated with systemic and
We examined activities of tyrosine hydroxylase (TH) and phenylethanolamine-N-methyl transferase (PNMT) and concentrations of norepinephrine (NE) in seven brain regions and the spinal cord of Wistar rats with elevated blood pressures 1 week and 4 weeks after denervation of carotid and aortic
Carcinoembryonic antigen-related cell adhesion molecule 1 (CEACAMl), a substrate of the insulin receptor tyrosine kinase, regulates insulin action by promoting insulin clearance. Global null mutation of Ceacam1 gene (Cc1(-/-)) results in features of the metabolic syndrome, including insulin
Neurons immunoreactive for Fos, the protein product of the immediate early gene c-fos, have been compared in the rostral ventral medulla and spinal cord of conscious normotensive Wistar-Kyoto rats (WKY) and spontaneously hypertensive rats (SHR) after baroreceptor unloading. Hypotension induced by a
