The goal of this study is to elucidate the formation of molecular gradients made of semifluorinated organosilanes (SFOs) on flat substrates by using a methodology developed by Chaudhury and Whitesides (Science 1992, 256, 1539). We use surface-sensitive combinatorial near-edge X-ray absorption fine structure (combi-NEXAFS) spectroscopy to measure the position-dependent concentration and orientat...
Pregnancy is characterized by increased blood volume and baseline sympathetic nerve activity (SNA), vasodilation, and tachycardia. Relaxin (RLX), an ovarian hormone elevated in pregnancy, activates forebrain sites involved in control of blood volume and SNA through ANG II-dependent mechanisms and contributes to adaptations during pregnancy. In anesthetized, arterial baroreceptor-denervated nonp...
<span lang="EN-US">This paper proposed modified sunflower optimization (MSFO) for the combination of network reconfiguration and distributed generation placement problem (NR-DGP) to minimize power loss electric distribution system (EDS). Sunflower (SFO) is inspired form ideal plant motion get sunlight its reproduction. To enhance performance SFO, it MSFO wherein, pollination mortality tec...
Direct intracerebroventricular injection of angiotensin II (ANG II) causes increases in blood pressure and salt and water intake, presumably mimicking an effect mediated by an endogenous mechanism. The subfornical organ (SFO) is a potential source of cerebrospinal fluid (CSF), ANG I, and ANG II, and thus we hypothesized that the SFO has a secretory function. Endogenous levels of angiotensinogen...
The recent discovery of prokineticin 2 (PK2) expression in the suprachiasmatic nucleus and its receptors in critical autonomic control centers of the brain, including the subfornical organ (SFO), suggests the intriguing possibility that PK2 regulates the excitability of SFO neurons and thus influences autonomic function. Using current-clamp techniques to record from dissociated SFO neurons, we ...
The subfornical organ (SFO) plays a pivotal role in body fluid homeostasis through its ability to integrate neurohumoral signals and subsequently alter behavior, neuroendocrine function, and autonomic outflow. The purpose of the present study was to evaluate whether selective activation of SFO neurons using virally mediated expression of Designer Receptors Exclusively Activated by Designer Drug...
Previous studies clearly demonstrated acute actions of angiotensin II (ANG II) at one of the central circumventricular organs, the subfornical organ (SFO), but studies demonstrating a role for the SFO in the chronic actions of ANG II remain uncertain. The purpose of this study was to examine the role of the SFO in the chronic hypertensive phase of ANG II-induced hypertension. We hypothesized th...
میکرواستخراج مایع-مایع پخشی (dllme) و ترکیب آن با روش هایی مانند استخراج با اولتراسونیک (uase) و استخراج با فاز جامد (sfe) جهت استخراج و پیش تغلیظ بعضی داروها، علف کش ها، حشره کش-ها و کاتیون های سنگین سرب و آرسنیک مورد استفاده قرار گرفت. در کار اول، ترکیب روش میکرواستخراج مایع - مایع پخشی (dllme) و دستگاه hplc مجهز به آشکارساز جذبی برای استخراج و اندازه گیری توفوردی، آلاکلر و آترازین در نمونه ه...
در کار اول، ترکیب روش میکرواستخراج مایع - مایع پخشی (dllme) و دستگاه hplc مجهز به آشکارساز جذبی برای استخراج و اندازه گیری bpa در نمونه های آبی به کار گرفته شد. تحت شرایط بهینه (142 میکرولیتر کلروفرم، 2 میلی لیتر استون و بدون اضافه کردن نمک) منحنی کالیبراسیون در محدوده 100-5/0 میکروگرم بر لیتر و حد تشخیص برابر 07/0 میکروگرم بر لیتر برای bpa می باشد. در کار دوم، روش dllme به عنوان یک روش تهیه نم...
AIMS The current study was designed to evaluate if angiotensin II mediates the hypothermic effects of ethanol, and to determine if the effects of angiotensin are mediated centrally. We also tested the hypothesis that the subfornical organ (SFO) is a site responsible for the alterations in body temperature and aerial righting reflex mediated by ethanol and for the modulation of ethanol consumpti...
