Background: Hypertension is one of the major cardiovascular risk factors affecting more than one billion people. The low awareness of the disease is one of the greatest difficulties related to hypertension. The population screening for hypertension is widely recognized as an effective strategy to detect new cases, but until now, ...

Despite reduction in cardiovascular (CV) events and end-organ damage with the current pharmacologic strategies, CV disease remains the primary cause of death in the world. Pharmacological therapies based on the renin angiotensin system (RAS) blockade are used extensively for the treatment of hypertension, heart failure, and CV remodeling but in ...

Cricoid pressure, as part of rapid sequence induction, may on occasion worsen laryngoscopic views and intubating conditions. We investigated whether allowing the assistant applying cricoid pressure to view the video laryngoscope screen would improve the laryngoscopic views compared to when they were blinded to the video screen. Laryngoscopy using the ...

Hypertension is a multifactorial disease in which the interplay of genetic and environmental factors that maintain blood pressure stable throughout life is altered. Cytochrome P450 (CYP)-derived metabolites of arachidonic acid such as epoxyeicosatrienoic acids (EETs) and 20-hydroxyeicosatetraenoic acid (20-HETE), active on vascular tone, endothelial function and renal sodium reapportion, have ...

Cytochrome c(5) of pressure-sensitive Shewanella livingstonensis (SL cytc(5)) exhibits lower thermal stability than a highly homologous counterpart of pressure-tolerant Shewanella violacea. This stability difference is due to an enthalpic effect that can be attributed to the amino acid residue at position 50 (Leu or Lys). These cytc(5) proteins are appropriate ...

Androgen plays an important role in blood pressure regulation. Epidemiological studies have shown that men have a higher prevalence for developing hypertension than aged-matched, premenopausal women. Interestingly, postmenopausal women and women with polycystic ovary syndrome, both of which have increased endogenous androgen production, have elevated risks for hypertension suggesting that ...

Peroxisome proliferator-activated receptor-alpha (PPAR-α) activation by fenofibrate reduces blood pressure and sodium retention during DOCA-salt hypertension. PPAR-α activation reduces the expression of inflammatory cytokines, such as interleukin-6 (IL-6). Fenofibrate also induces cytochrome P450 4A (CYP4A) and increases 20-hydroxyeicosatetraenoic acid (20-HETE) production. This study tested whether the administration of fenofibrate would ...

This retrospective study investigated the circadian and infradian characteristics of blood pressure and heart rate in 26 patients with traumatic head injury in a persistent vegetative state (PVS). Systolic and diastolic blood pressures and heart rate were measured every hour for the first 240 h (10 days) following hospital admission. ...

Woman have lower rate of hypertension than man but it is still elusive how such gender difference can be explained by kinetic epidemiological curves. The aim of this paper was to develop a multi-state model for delineating the kinetic epidemiology of hypertension according to the Seventh Report of the Joint ...

In observational studies, the relationship between blood pressure and end-stage renal disease (ESRD) is direct and progressive. The burden of hypertension-related chronic kidney disease and ESRD is especially high among black patients. Yet few trials have tested whether intensive blood-pressure control retards the progression of chronic kidney disease among black ...

Physical fitness performance is an important health correlate yet is often unrelated to sedentary behaviour in early adolescence. In this study, we examined the association of sedentary behaviour (i.e. screen time) with weight-related health markers and blood pressure, after controlling for cardiorespiratory fitness performance. American middle school students (N = 153, 56% ...

Broken pellets and fines are produced when pellets are handled. The resistance to air flow was measured for clean pellets and for pellets mixed with 1-20% broken pellets (fines). A pellet diameter was 6mm. The lengths ranged from 6 to 12 mm. Clean pellets were defined as particles that remained ...

We present the apparent mass measurements at the bottom of granular packings for different bead and silo sizes. The redirection parameter K in Janssen theory is found to increase with the ratios of the diameter of the silo to the bead. We attribute this feature to the friction between the ...

BACKGROUND: Microalbuminuria and hypertension have long been associated with a guarded prognosis in human patients with a variety of diseases. In veterinary medicine, tests for microalbuminuria have been used for detecting early kidney damage, but there is little information regarding its association with high blood pressure in dogs with chronic ...

Recommendations for early detection and management of elevated blood pressure through opportunistic clinic-based screening may be inadequate for the rural population in India as access to health facilities is limited. Sixteen Health Aides (trained primary care workers) were trained to measure blood pressure using a standardized training procedure. Six of ...

AIMS: Non-alcoholic fatty liver disease (NAFLD) is associated with features of the metabolic syndrome (MetS) and may be an expression of the syndrome within the liver. Using screening data from the Nateglinide And Valsartan in Impaired Glucose Tolerance Outcomes Research (NAVIGATOR) study (n = 42 149), we examined whether alanine ...

Hypertension is both the cause and effect of kidney disease. Together these two diseases have become epidemics in our society and are associated with an increased risk of cardiovascular events. Over the last several decades multiple clinical and transplant studies have shown the kidney to be an important determinant of ...

Both chronic kidney disease (CKD) and masked hypertension (MHT) are known to be linked with an increased risk of cardiovascular disease (CVD), but their relationship has remained unclear. The present study aimed to evaluate the CKD incidence in individuals with MHT in the general Japanese population. We recorded self-measured blood ...

In general, adherence to blood pressure guidelines is low. We assessed whether hypertension recognition and control in North Carolina was consistent with the seventh report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC 7) in primary care practices participating in a quality ...

INTRODUCTION: Hypertension is prevalent in the general population. Emergency Department (ED) follow-up studies show persistence of blood pressure elevations in up to 50% of patients, and ED screening for hypertension has been recommended. Blood pressure elevations are often ignored or attributed to pain or anxiety. Our purpose was to document ...

Blood pressure at the ankle level is a reliable indicator of peripheral arterial disease (PAD) and the ankle brachial index (ABI) is a useful non-invasive screening tool for the early detection of atherosclerosis. In the first part of the study, systolic blood pressures obtained by oscillometry and plethysmography were compared ...

Hypertension is a serious medical problem affecting millions of people worldwide. A key protein regulating blood pressure is the Epithelial Na(+) Channel (ENaC). In accord, loss of function mutations in ENaC (PHA1) cause hypotension, whereas gain of function mutations (Liddle syndrome) result in hypertension. The region mutated in Liddle syndrome, ...

Chronic kidney disease is both a cause and a consequence of hypertension. Extracellular volume expansion is an important, if not the most important, contributing factor to hypertension seen in chronic kidney disease. Beyond volume expansion, chronic kidney disease-related hypertension is without truly defining characteristics. Consequently, the sequencing of antihypertensive medications ...

Epidemiological and experimental data strongly suggest that cardiovascular diseases can originate from an aberrant environment during fetal development, a phenomenon referred to as perinatal programming. This review will focus on the role of the kidneys in determining blood pressure, and how (re)programming the renal development can persistently ameliorate hereditary hypertension. ...

Epidemiological and experimental studies have documented both the rising burden of diastolic heart failure (DHF) and several mechanisms that distinguish this disease from systolic heart failure (SHF). Controversies continue to surround the term 'DHF' as well as its existence as a pathophysiological entity distinct from SHF. Approximately half of all ...

OBJECTIVE: To observe and analyze the occurrence and management of the trigemino-cardiac reflex (TCR) defined as the phenomenon of abrupt drops in heart rate (HR) and blood pressure during skull base surgery.

An acutely hypertensive 55 year-old male experienced seizures and cortical blindness post-operatively. CT scans demonstrated hypointensities in the occipital lobes bilaterally. MRI revealed symmetrical bilateral hyperintense signals in the same region, involving both grey and white matter. Thromboembolic screening investigations including vertebral artery doppler studies were normal and echocardiography demonstrated ...

We report a molecular simulation study for CO2 storage in metal-organic frameworks (MOFs). As compared to the aluminum-free and cation-exchanged ZSM-5 zeolites and carbon nanotube bundle, IRMOF1 exhibits remarkably higher capacity. Incorporation of Na(+) cations into zeolite increases the capacity only at low pressures. By variation of the metal oxide, ...

Long term macrobenthos data together with physical habitat parameters were analysed to investigate spatial and temporal changes at an estuary under different anthropogenic pressures, mainly increasing shellfish farming. The aim was to assess the possible impacts of these pressures on the macrobenthic communities by comparing a period before and after ...

Kidney injury in lithotripsy can lead to long-term adverse effects, so minimizing injury is beneficial. We have found that injury is significantly reduced when shock wave (SW) administration is halted briefly- 3-minutes-early in treatment. Previous studies have shown that SWs stimulate renal blood vessels to constrict. Therefore, we tested the ...

Kidney disease and hypertension commonly coexist, yet the direction of their association is still debated. To evaluate whether early kidney dysfunction, measured by serum cystatin C levels and urinary albumin excretion, predates hypertension in adults without clinically recognized kidney or cardiovascular disease. Observational cohort study using data from 2000 to ...

BACKGROUND: Hypertension prevalence, awareness, treatment, and blood pressure control rates in the population with chronic kidney disease are limited. The objective of this study was to determine the state of blood pressure control in patients with chronic kidney disease. METHODS: This is a cross-sectional analysis of data of participants with ...

PURPOSE OF REVIEW: Recent experimental data shed light on the regulation of renalase, a secreted amine oxidase, which circulates in an inactive form (prorenalase). Abnormalities in the renalase pathway are evident not only in animal models of chronic kidney disease, but also during the development of hypertension, at a time ...

Information on vertical variations in hydraulic conductivity (K) can often shed much light on how a contaminant will move in the subsurface. The direct-push injection logger has been developed to rapidly obtain such information in shallow unconsolidated settings. This small-diameter tool consists of a short screen located just behind a ...
