RATIONALE: The Reasoned Action Approach (RAA) developed out of the Theory of Reasoned Action and Theory of Planned Behavior but has not yet been widely applied to understanding health behaviors. The present research employed the RAA in a prospective design to test predictions of intention and action for groups of protection and risk behaviors separately in the same sample. OBJECTIVE: To test the RAA for health protection and risk behaviors. METHOD: Measures of RAA components plus past behavior were taken in relation to eight protection and six risk behaviors in 385 adults...

In this study, a rapid reverse-transcription recombinase aided amplification (RT-RAA) assay was developed to detect respiratory syncytial virus (RSV) subgroups A and B, respectively. The reaction was performed at 39°C in less than 30min. The analytical sensitivities of RSVA and RSVB at 95% probability by probit regression analysis were 38copies per reaction and 35 copies per reaction, respectively, and no cross reactions with other related respiratory viruses were observed. The RT-RAA assay was further utilized to detect and subgroup 306 clinical specimens and the results showed that 79(25...

Lepidium apetalum Willd has been used to reduce edema and promote urination. Cis-desulfoglucotropaeolin (cis-DG) and trans-desulfoglucotropaeolin (trans-DG) were isolated from Lepidium apetalum Willd, and caused a significant increase in cell viability in a hypertonic model in NRK52e cells. In the hypertonic model, cis-DG and trans-DG significantly promoted the cell viability of NRK52e cells and inhibited the elevation of Na⁺ in the supernatant, inhibited the renin-angiotensin-aldosterone (RAAS) system, significantly reduced the levels of angiotensin II (Ang II) and aldosterone (ALD), and lowered aquaporin-2 (AQP2) and Na⁺-K⁺ ATP content in renal medulla...

Dapagliflozin (DAPA), a sodium-glucose co-transporter 2 (SGLT2) inhibitor, is known to have a beneficial diuretic effect, in addition to a glucose-lowering effect. Although SGLT2 inhibitor has been reported, the increase of hyperkalemia in patients treated with renin-angiotensin-aldosterone system (RAAS) inhibitors, their mechanism of action is unclear. We report the first case of a type 2 diabetes (T2DM) patient with potential mineralocorticoid deficiency who developed hyperkalemia after administration of DAPA...

The arguments set forth by religious authority are important since they play a crucial role in shaping the social values of the public and influence the decision of individuals in practice pertaining to bioethical issues. The Religious Affairs Administration (RAA) was established at the inception of the Republic of Turkey in 1924 to guide religious considerations moving out of the Ottoman caliphate to a secular bioethical framework. In this article, the bioethical views of the RAA under Islamic tradition is examined and contrasted with those influenced by the Roman Catholic and Orthodox Judaic traditions...

The presumed superiority of renin-angiotensin-aldosterone system (RAAS)-blocking agents over other antihypertensive agents in patients with diabetes to delay development of end-stage kidney disease (ESKD) has recently been challenged. In addition, there is ongoing uncertainty whether RAAS-blocking agents reduce mortality and/or delay ESKD in patients with diabetes and chronic kidney disease (CKD) stages 3-5. In this subgroup, there might be an expedited need for renal replacement therapy (RRT) when RAAS-blocking agents are used...

BACKGROUND AND OBJECTIVES: Diabetic kidney disease is the leading cause of end-stage chronic kidney disease. The renin-angiotensin-aldosterone system (RAAS) blockade has been shown to slow the progression of diabetic kidney disease. Our objectives were: to study the percentage of patients with diabetic kidney disease treated with RAAS blockade, to determine its renal function, safety profile and assess whether its administration is associated with increased progression of CKD after 3 years of follow-up...

BACKGROUND: Renal denervation (RDN) is a promising therapeutic method in cardiology. Its currently most investigated indication is resistant hypertension. Other potential indications are atrial fibrillation, type 2 diabetes mellitus and chronic renal insufficiency among others. Previous trials showed conflicting but promising results, but the real benefits of RDN are still under investigation. Patients with renal insufficiency and resistant hypertension are proposed to be a good target for this therapy due to excessive activation of renal sympathetic drive...

Vitamin D and parathormone (PTH) are hormones regulating calcium and phosphorus homeostasis. The aim of the article is to summarize the current knowledge in the field and to assess its impact on heart failure (HF) pathogenesis. PTH serum concentration being frequently elevated in patients with HF has negative impact on circulatory system stimulating myocardial fibrosis, wall thickening and reninangiotensin-aldosterone system (RAAS) activity. PTH reacts with smooth muscle cells receptors mediating adrenergic and chronotropic activation resulting in increased oxidative stress, endothelial dysfunction, intracellular calcium overload and has negative influence on prognosis in chronic HF patients...

Since 1988, the German Embryotox institute combines individual counselling of pregnant women and their health care providers (HCP) with research on drug safety in pregnancy. In addition, Embryotox offers web-based information which covers the most important and most frequently requested pharmaceutical substances. In contrast to ready-made drug risk information in package leaflets and other product information, individual counselling considers different clinical settings such as (1) looking for a drug of choice or planning pregnancy under medication, (2) risk assessment of a particular drug that has already been taken during an (unplanned) pregnancy and (3) evaluation of an adverse pregnancy outcome in association with a particular medication...

Oxygen sensing mechanisms are vital for homeostasis and survival. When oxygen levels are too low (hypoxia), blood flow has to be increased, metabolism reduced, or a combination of both, to counteract tissue damage. These adjustments are regulated by local, humoral, or neural reflex mechanisms. The kidney and the carotid body are both directly sensitive to falls in the partial pressure of oxygen and trigger reflex adjustments and thus act as oxygen sensors. We hypothesize a cooperative oxygen sensing function by both the kidney and carotid body to ensure maintenance of whole body blood flow and tissue oxygen homeostasis...

Recent studies demonstrate that maternal hypertension during pregnancy sensitizes an angiotensin (ANG) II-induced increase in blood pressure (BP) in adult male offspring that was associated with upregulation of mRNA expression of several renin-angiotensin-aldosterone system (RAAS) components and NADPH oxidase in the lamina terminalis (LT) and paraventricular nucleus (PVN). The purpose of the present study was to test whether there are sex differences in the maternal hypertension-induced sensitization of ANG II hypertension, and whether sex hormones are involved in the sensitization process...

Cardiac fibrosis is a common pathological process in cardiac disease and may lead to heart failure. It can also cause sudden death even in those without cardiac symptoms. Tissue fibrosis can be categorized into two categories: replacement fibrosis (also called reparative fibrosis) and reactive fibrosis. In replacement fibrosis, infiltration of inflammatory cells and accumulation of Extracellular Matrix (ECM) proteins are the initial steps in forming scarlike fibrotic tissue after acute cardiac injury and cardiac cell necrosis...

BACKGROUND: Dielectric damage occurring in vivo to neural electrodes, leading to conductive material exposure and impedance reduction over time, limits the functional lifetime and clinical viability of neuroprosthetics. We used silicon micromachined Utah Electrode Arrays (UEAs) with iridium oxide (IrOx) tip metallization and parylene C dielectric encapsulation to understand the factors affecting device resilience and drive improvements. NEW METHOD: In vitro impedance measurements and finite element analyses were conducted to evaluate how exposed surface area of silicon and IrOx affect UEA properties...

AIMS: The evaluation of the local Renin-Angiotensin-Aldosterone system (RAAS) gene expressions in the heart of ovariectomized (OVX) apolipoprotein E deficient mice (ApoE). METHODS: Four-months old C57BL/6 female mice (wild-type, wt, n=20), and ApoE female mice (n=20), were submitted to OVX or a surgical procedure without ovary removal (SHAM) and formed four groups (n=10/group): SHAM/wt, SHAM/ApoE, OVX/wt, and OVX/ApoE. KEY FINDINGS: OVX led to greater body mass, plasma triglycerides (TG) and total cholesterol, and resulted in insulin resistance and altered RAAS gene expressions in the heart tissue...

Background: Left ventricular (LV) diastolic dysfunction characterizes heart failure with a preserved ejection fraction. Although it is recognized that the renin-angiotensin-aldosterone-system (RAAS) decreases LV diastolic function, whether systemic angiotensinogen contributes to these effects is uncertain. Hence the aim was to determine the relationship between systemic angiotensinogen concentrations and LV diastolic function. Methods: Left ventricular diastolic function was determined from the mean of the lateral and septal wall myocardial tissue lengthening at the mitral annulus (average e') and from the ratio of early transmitral blood flow velocity (E) to average e' (E/e') in 445 black African participants from a community sample...

BACKGROUND: Heart failure (HF) remains a significant cause of morbidity and mortality. Multiple trials over the past several years have examined the effects of both angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin II receptor blockers (ARBs) in the treatment of left ventricular dysfunction, both acutely after myocardial infarction and in chronic heart failure. Yet, there is still confusion regarding the relative efficacy of rennin-angiotensin-aldosterone system (RAAS) inhibition...
