The objective of this study was to compare strain and gender differences in kidney and heart norepinephrine (NE) content and turnover rate in normotensive Wistar-Kyoto rats (WKY) and spontaneously hypertensive rats (SHR, SHR/a, and SHR/y). Our laboratory has shown that the Y chromosome has a significant effect on blood pressure in the SHR model of hypertension through the use of two new rat sta...
The hypothesis that oral supplementation with virgin coconut oil (Cocos nucifera L.) and exercise training would improve impaired baroreflex sensitivity (BRS) and reduce oxidative stress in spontaneously hypertensive rats (SHR) was tested. Adult male SHR and Wistar Kyoto rats (WKY) were divided into 5 groups: WKY + saline (n = 8); SHR + saline (n = 8); SHR + coconut oil (2 mL·day(-1), n = 8); S...
Mitochondrial dysfunction is associated with cardiovascular damage; however, data on a possible association with kidney damage are scarce. Here we aimed at investigating whether a) kidney impairment is related to mitochondrial dysfunction, and b) angiotensin II blockade, as compared to Ca-channel blockade, can reverse potential mitochondrial changes in hypertension. Eight-weekold male spontaneo...
Although baroreceptors are known to reset to operate in a higher pressure range in spontaneously hypertensive rats (SHR), the total profile of dynamic arterial pressure (AP) regulation remains to be clarified. We estimated open-loop transfer functions of the carotid sinus baroreflex in SHR and Wistar Kyoto (WKY) rats. Mean input pressures were set at 120 (WKY₁₂₀ and SHR₁₂₀) and 160 mmHg (SHR₁₆₀...
Our laboratory has shown that the Y chromosome has a significant effect on blood pressure in the spontaneously hypertensive rat (SHR) model of hypertension and that the testes and androgen receptor contribute to the blood pressure rise. As an extension of our research, we have developed two new rat strains, SHR/a and SHR/y (F11) to study the Y chromosome. The objectives of the following researc...
Previous studies have demonstrated that oxidative stress contributes to hypertension and treatments with either antioxidant or immunosuppressive/anti-inflammatory agents improve hypertension in spontaneously hypertensive rats (SHR). The present study was performed to determine if the antihypertensive effects of an antioxidant-rich diet are associated with reduction in the renal immune infiltrat...
PURPOSE Although increased oxidative stress is a major component of diabetic hypertensive cardiomyopathy, research into the effects of antioxidants on cardiac remodeling remains scarce. The actions of antioxidant apocynin include inhibiting reactive oxygen species (ROS) generation by nicotinamide adenine dinucleotide phosphate (NADPH) oxidases and ROS scavenging. We evaluated the effects of apo...
The urban thermal environment is impacted by changes in landscape patterns resulting from expansion and seasonal variation. In order to cope effectively with heat island (UHI) effects improve the living microclimate, an analysis of heating effect impervious surface areas (ISA) cooling vegetation needed. this study, Landsat 8 data four seasons were used derive percent ISA fractional cover (FVC) ...
در این مقاله، روش نگاشت ورودی کنترلی شبکه¬ای برای کنترل دستگاه های صنعتی و ماشین¬های موجود در کارخانجات با بهره¬گیری از شبکه های بی¬سیم با پهنای باند کوچک پیشنهاد شده است. برای رسیدن به این هدف، ابتدا روشی برای جبران سازی تأخیر ثابت پیشنهاد می¬شود که بر پایه¬ی حداقل نمودن اختلاف ورودی¬های کنترلی دستگاه تحت کنترل مختل شده در دو حالت زمان¬پیوسته و تأخیری استوار است. به¬این ترتیب که برای سیستم زما...
