We investigate high-pressure induced phase transitions of YF3 and Eu-doped YF3 (YF3:Eu(3+)) by using the angular dispersive synchrotron X-ray diffraction technique at room temperature. It is found that the starting orthorhombic phase transforms into a new high-pressure phase which is identified as hexagonal structure in both YF3 and YF3:Eu(3+). The ...

A recent trial showed that setting PEEP according to end-expiratory transpulmonary pressure (P(pl,ee)) in acute lung injury/acute respiratory distress syndrome (ALI/ARDS) might improve patient outcome. P(pl,ee) was obtained by subtracting the absolute value of esophageal pressure (P(es)) from airway pressure an invariant value of 5 cm H(2)O. The goal of ...

Obesity-related hypertension in pediatric patients is becoming more prevalent around the world as a consequence of the childhood obesity epidemic. Hypertension and the metabolic abnormalities associated with obesity will significantly increase the health risks for these children as they grow into adulthood. The pathophysiology of obesity-related hypertension is complex, and ...

The prevalence of obesity among children and adolescents increased by almost threefold from the 1970s to 2000. We examined whether these secular changes in BMI were accompanied by increases in blood pressure levels. A total of 24,092 examinations were conducted among 11,478 children and adolescents (aged 5-17 years) from 1974 ...

Ambulatory blood pressure monitoring (ABPM) has been proposed as a useful tool for more accurately diagnosing hypertension (HTN) and evaluating blood pressure (BP) response in pediatric anti-hypertensive trials. ABPM captures multiple BP measurements during routine daily activities and is thus an excellent method for identifying white-coat HTN. Additionally, ABPM measurements ...

High-altitude destinations are visited by increasing numbers of children and adolescents. High-altitude hypoxia triggers pulmonary hypertension that in turn may have adverse effects on cardiac function and may induce life threatening high-altitude pulmonary edema (HAPE), but there is limited data in this young population. We, therefore, assessed in 118 non-acclimatized ...

PURPOSE OF REVIEW: In contrast to adult literature, data for pressure ulcers in children is limited. Incidence and prevalence of this skin integrity issue in pediatric hospitals is still widely unknown, perhaps because increased awareness and prevention of the phenomenon have been slow to develop. Moreover, identification of at-risk patients ...

BACKGROUND: Prehypertension is defined as blood pressure (BP) ≥90th percentile, or ≥120/80 mmHg, but <95th percentile for age, sex, and height. Since the definition is made by conventional BP measurements and office BP can be quite variable, we studied whether prehypertension could be differentiated by ambulatory BP monitoring from normotension or ...

Systemic arterial hypertension in children has traditionally been thought to be secondary in origin. Increased incidence of risk factors like obesity, sedentary life-styles, and faulty dietary habits has led to increased prevalence of the primary arterial hypertension (PAH), particularly in adolescent age children. PAH has become a global epidemic worldwide ...

The association between fructose and increased blood pressure is still incompletely defined, because experimental studies have produced dissimilar conclusions. Amplified vasopressor responses to minimal stimuli and differing responses to fructose in peripheral versus central sites may explain the controversy. Fructose induces systemic hypertension through several mechanisms mainly associated with deleterious ...

Hypertension-induced renal injury is characterized by inflammation, fibrosis and proteinuria. Previous studies have demonstrated that N-acetyl-Ser-Asp-Lys-Pro (Ac-SDKP) inhibits renal damage following diabetes mellitus and antiglomerular basement membrane nephritis. However, its effects on low-renin hypertensive nephropathy are not known. Thus, we hypothesized that Ac-SDKP has renal protective effects on deoxycorticosterone acetate ...

Dietary salt intake is associated with high brachial blood pressure (BP) and increased risk of cardiovascular disease. We investigated whether changes in dietary salt intake are associated with changes in central BP and wave reflection in healthy volunteers. Ten healthy normotensive male volunteers (22-40 yr) participated in a 6-wk double-blind ...

Epidemiologic evidence suggests that prenatal growth influences adult blood pressure. Nutritional factors, including salt intake, also influence blood pressure. However, it is unknown whether prenatal growth modifies the association between salt intake and blood pressure in later life. Our aim was to examine whether the relation between salt intake and ...

Excessive salt intake is a major risk factor for hypertension. However, the underlying molecular relationship between salt and hypertension is not fully understood. Recently discovered cardiotonic steroids, such as endogenous ouabain and other steroids, have been proposed as candidate intermediaries. Plasma cardiotonic steroids are significantly elevated in patients with essential ...

Reactive oxygen species (ROS) contribute to various models of hypertension, including deoxycorticosterone acetate (DOCA)-salt-induced hypertension. Recently, we have shown that ROS, generated by cytochrome P-450 1B1 (CYP1B1) from arachidonic acid, mediate vascular smooth muscle cell growth caused by angiotensin II. This study was conducted to determine the contribution of CYP1B1 ...

In this study, we investigated the effect of pressure on the formation and decomplexation of [2]pseudorotaxanes. High pressure accelerated the formation of [2]pseudorotaxanes in an aprotic nonpolar solvent (CDCl(3)/CD(3)CN) via the slipping approach when using two crown ether/secondary ammonium salt systems: dibenzo[24]crown-8/bis(cyclohexylmethyl)ammonium salt (1a/2a) and tetrabenzo[24]crown-8/dibenzylammonium salt (1b/2b). The influence ...

Primary (essential) hypertension has been shown to be mediated by a relative impairment in sodium excretion by the kidney, but the mechanisms responsible for this defect are still being clarified. Increasing evidence suggests a role for subtle acquired renal injury in mediating this process. Microvascular injury is present in the ...

This study was designed to test whether altered aldosterone-related sodium handling leads to salt-sensitive blood pressure in diabetes and thus may exaggerate end-organ damage. Zucker diabetic fatty (ZDF) rats, a model of type 2 diabetes, and Zucker lean (ZL) rats, as euglycemic controls, were divided into groups receiving normal (0.28%) ...

Mechanisms promoting the transition from hypertensive heart disease to heart failure with preserved ejection fraction are poorly understood. When inappropriate for salt status, mineralocorticoid (deoxycorticosterone acetate) excess causes hypertrophy, fibrosis, and diastolic dysfunction. Because cardiac mineralocorticoid receptors are protected from mineralocorticoid binding by the absence of 11-beta hydroxysteroid dehydrogenase, salt-mineralocorticoid-induced ...

Microvascular rarefaction occurs in hypertension. We carried out a 12-week randomized double-blind crossover trial to determine the effect of a modest reduction in salt intake on capillary rarefaction in 71 whites, 69 blacks, and 29 Asians with untreated mildly raised blood pressure. Both basal and maximal (during venous congestion) skin ...

The mRen(2).Lewis (mRen2) strain is an ANG II-dependent model of hypertension expressing marked sex differences in blood pressure and tissue injury that also exhibits estrogen and salt sensitivity. Because estrogen and salt influence angiotensinogen (AGT), circulating and renal expression of the protein were assessed in the mRen2 using a sensitive ...
