Morbidity and mortality attributable to hypertension are higher in black essential hypertensive (EH) compared with white EH patients, possibly related to differential effects on vascular injury and repair. Although circulating endothelial progenitor cells (EPCs) preserve endothelial integrity, inflammatory endothelial cells (IECs) detach from sites of injury and represent markers of vascular da...
Three insect peptide hormones, eclosion hormone (EH), ecdysis-triggering hormone (ETH) and crustacean cardioactive peptide (CCAP), have been implicated in controlling ecdysis behavior in insects. This study examines the interactions between these three peptides in the regulation of the ecdysis sequence. Using intracellular recordings, we found that ETH is a potent activator of the EH neurons, c...
Let EG be a stable principal G–bundle over a compact connected Kähler manifold, where G is a connected reductive linear algebraic group defined over C. Let H ⊂ G be a complex reductive subgroup which is not necessarily connected, and let EH ⊂ EG be a holomorphic reduction of structure group. We prove that EH is preserved by the Einstein–Hermitian connection on EG. Using this we show that if EH ...
Extracampine hallucinations (EH), the sense of a presence or fleeting movement in the absence of an associated visual percept, have been reported in Parkinson's disease (PD) patients but their prevalence, characteristics, and temporal relationship to visual hallucinations (VH) remain unclear. Given that, VH are predictive of cognitive impairment in PD, improved understanding of EH may have sign...
The biological actions of angiotensin III (AIII) in animals have been reported to be stimulation of aldosterone secretion and vasoconstriction. However, the biological actions of AIII in human essential hypertension (EH) have not been evaluated. Twenty ng/Kg/min of AIII was infused intravenously for 30 min into 6 normal subjects and 24 patients with EH. The systolic blood pressure was elevated ...
We hypothesized that episodic hypoxia (EH) leads to alterations in chemoreflex characteristics that might promote the development of central apnea in sleeping humans. We used nasal noninvasive positive pressure mechanical ventilation to induce hypocapnic central apnea in 11 healthy participants during stable nonrapid eye movement sleep before and after an exposure to EH, which consisted of fift...
Repetitive episodic (18-24 s twice per minute) hypocapnic hypoxia (HH) administered chronically (7 h/day, 35 days) to Sprague-Dawley or Wistar-Kyoto rats results in a sustained increase in daytime blood pressure (BP). We examined acute and chronic BP response to episodic HH and eucapnic hypoxia (EH) in borderline hypertensive rats [first generation (F1) cross between spontaneously hypertensive ...
Insect growth is punctuated by molts, during which the animal produces a new exoskeleton. The molt culminates in ecdysis, an ordered sequence of behaviors that causes the old cuticle to be shed. This sequence is activated by Ecdysis triggering hormone (ETH), which acts on the CNS to activate neurons that produce neuropeptides implicated in ecdysis, including Eclosion hormone (EH), Crustacean ca...
Vascular endothelial cells produce nitric oxide (NO), which contributes to the regulation of blood pressure and regional blood flow. Polymorphisms of the endothelial nitric oxide synthase (eNOS) gene are associated with coronary artery disease; however, associations between polymorphism (G894T) of the eNOS gene and essential hypertension remain unclear. This study was designed to investigate th...
