We investigated acute and chronic effects of CB1 cannabinoid receptor blockade in renin-angiotensin system-dependent hypertension using rimonabant (SR141716A), an orally active antagonist with central and peripheral actions. In transgenic (mRen2)27 rats, a model of angiotensin II-dependent hypertension with increased body mass and insulin resistance, acute systemic blockade of CB1 receptors ...

Piezoelectric materials respond to external stimuli by adjusting atomic positions. In solid-solutions, the changes occurring in atomic scale are very complex since the short- and long-range order are different. Standard methods used in diffraction data analysis fail to model the short-range order accurately. Pressure-induced cation displacements in ferroelectric Pb(Zr0.45Ti0.55)O3 perovskite ...

With proteinaceous-liquid flooding of discrete alveoli, a model of the edema pattern in the acute respiratory distress syndrome, lung inflation over expands aerated alveoli adjacent to flooded alveoli. Theoretical considerations suggest that the over-expansion may be proportional to surface tension, T. Yet recent evidence indicates proteinaceous edema liquid may not ...

Intestinal ischemia-reperfusion injury is one of the main factors leading to multiple organ failure after resuscitation of prolonged hemorrhagic shock; however, the current conventional fluid resuscitation still cannot effectively reduce intestinal injury caused by prolonged hemorrhagic shock. To investigate the effect of ECMO resuscitation on alleviating intestinal ischemia-reperfusion injury in ...

It is known that blood pressure variability (BPV) can independently affect target organ damage (TOD), even with normal blood pressure. There have been few studieson chronic kidney disease (CKD) patients. We evaluated the relationship between BPV and TOD in a cross-sectional, multicenter study on hypertensive CKD patients. We evaluated 1,173 ...

Most patients with essential hypertension do not exhibit substantial renal damage. Renal autoregulation by preventing glomerular transmission of systemic pressures has been postulated to mediate this resistance. Conversely, malignant nephrosclerosis (MN) has been postulated to develop when severe hypertension exceeds a critical ceiling. If the concept is valid, even modest ...

The call for early detection of hypotension creates a heavy demand for new methods that can monitor trends in blood pressure (BP) levels continuously and noninvasively. Photoplethysmography (PPG) is widely used in hemodynamic analysis. We assessed the feasibility of toe PPG in tracing BP trends using BP readings obtained by ...

Epidemiological, preclinical and clinical studies established the association between high alcohol consumption and hypertension. However the mechanism through which alcohol raises blood pressure remains elusive. Several possible mechanisms have been proposed such as an imbalance of the central nervous system, impairment of the baroreceptors, enhanced sympathetic activity, stimulation of the ...

Angiotensin II type 1 receptor blockers (ARBs) are widely used in treating hypertension. In the present study, we tested the hypothesis that a novel ARB, azilsartan medoxomil (AZL-M) will prevent renal and cardiovascular injury in the spontaneously hypertensive obese rat (SHROB), a model of cardiometabolic syndrome. Male SHROB were treated ...

Therapeutic mechanisms of action for hyperbaric oxygen (HBO2) therapy are based on elevation of both the partial pressure of inspired O2 and of the hydrostatic pressure. This last mechanism contributes to a compression of all gas-filled spaces in the body (Boyle's Law) and is relevant to treat conditions where gas ...

Salt sensitivity of blood pressure (BP) is an independent risk factor for cardiovascular morbidity. Up to 50% of patients with essential hypertension are salt-sensitive, as manifested by a rise in BP with salt intake. Several genetic variations have been identified as being associated with salt sensitivity. The present study aimed ...

Blood pressure can vary considerably during anesthesia. If blood pressure falls outside the limits of cerebrovascular autoregulation, children can become at risk of cerebral ischemic or hyperemic injury. However, the blood pressure limits of autoregulation are unclear in infants and children, and these limits can shift after brain injury. This ...

Ex vivo normothermic perfusion (EVNP) can reverse some of the detrimental effects of ischemic injury. However, in kidneys with warm and cold ischemic injury the optimal perfusion pressure remains undetermined. The aim of this study was to evaluate the effects of two different arterial pressures during EVNP. Porcine kidneys underwent static ...

Despite the increasing use of pre- and posthydration protocols and low-osmolar instead of high-osmolar iodine-containing contrast media, the incidence of contrast-induced nephropathy (CIN) is still significant. There is evidence that contrast media cause ischemia-reperfusion injury of the medulla. Remote ischemic preconditioning (RIPC) is a non-invasive, safe, and low-cost method to ...

High-pressure paint gun injuries are potentially devastating injuries that require emergent surgical incision and drainage. They result from erroneous equipment operation and accidental injection of a variety of substances at pressures high enough to breach the skin. The largely benign superficial appearance masks the extent of the underlying injury. In ...

Previous studies have reported that risk of cardiovascular morbidity and mortality substantially increases in hypertensive patients, especially among those with inadequate blood pressure control. Two common antihypertensive drug classes including thiazide diuretics and angiotensin-converting enzyme (ACE) inhibitors affect different enzymes in the renin-angiotensin-aldosterone system (RAAS). In the RAAS, angiotensinogen is ...

Little is known about the relationships between different systolic blood pressure (SBP) thresholds and their outcomes in acute intracerebral hemorrhage (ICH). We aimed to determine the associations of potential systolic blood pressure (SBP) thresholds with hematoma growth (HG) and clinical outcome in patients with acute ICH. 117 patients with acute ...

Central nervous system (CNS) administration of angiotensin II (Ang II) raises blood pressure (BP). The rise in BP reflects increased sympathetic outflow and a slower neuromodulatory pressor mechanism mediated by CNS mineralocorticoid receptors (MR). We investigated the hypothesis that the sustained phase of hypertension is associated also with elevated circulating ...

In patients suffering from brain injury, end-tidal PCO2 (PETCO2) monitoring is controversial but transcutaneous PCO2 (PtcCO2), which is noninvasive and utilizes real-time display, may be an alternative method. We hypothesized that PtcCO2 would be more accurate than PETCO2 for monitoring PaCO2 in severe brain injury patients. A prospective observational study ...

Controversy exists on the role of hyperoxia in major trauma with brain injury. Hyperoxia on arterial blood gas has been associated with acute lung injury and pulmonary complications, impacting clinical outcome. The hyperoxia could be reflective of the physiological interventions following major systemic trauma. Despite the standard resuscitation of patients ...
