The aim of this study was to investigate the effects of the antidiuretic hormone arginine vasopressin (AVP), which is released in vivo during dehydration and hypovolemia to prevent further water loss, on the activity of neurons in the subfornical organ (SFO). The SFO is a brain structure with an open blood-brain barrier and is critically involved in angiotensin II (ANG II)-dependent water intak...
Digital radio mondiale (DRM) is a terrestrial radio broadcasting standard to replace existing analogue AM and FM broadcasting, which is based on an orthogonal frequency division multiplexing (OFDM) technique. This paper focuses on the issue of estimating a sampling frequency offset (SFO) in OFDM-based broadcasting systems under frequency selective fading channels. In order to design a robust SF...
روش میکرواستخراج قطره آلی شناور منجمد شده به کمک امواج فراصوت قبل از اندازهگیری با تزریق در جریان-جذب اتمی شعله ای برای اندازه گیری پالادیم به کار گرفته شد. در این روش پالادیم پس از تشکیل کی لیت با استیل استون به قطرات ریز 1-آندکانول استخراج می شود. فاکتورهای مختلفی که بر استخراج و تشکیل کی لیت اثر می گذارند مانند ph، غلظت استیل استون، مدت زمان قرارگیری در حمام فراصوت، مدت زمان سانتریفوژ، نوع ...
Recent increased demand for stingless bee honey in Malaysia have stimulated alternative methods to increase honey yields by using plastic cups as artificial honey pots within the beehives. However, honey’s acidity may lead to possible migration of plastic additives, where prolonged consumption may affect body’s physiological responses. This study was carried out to determine the presence of dib...
The aim of this study was to investigate effects of oxytocin (OT) on electrical neuronal activities in rat subfornical organ (SFO) and compare its action with the well-described excitatory effects of blood-borne angiotensin II (ANG II) on the same SFO neurons. With the use of extracellular recordings from spontaneously active neurons in slice preparations of the SFO of male rats, 11.7% of teste...
Objective: Angiotensin (Ang) II by activating cytosolic phospholipase A2a (cPLA2a) releases arachidonic acid (AA), and the pro-hypertensive AA metabolites mediate Ang II-induced hypertension and associated pathogenesis. These fi ndings and the demonstration that Ang II increases blood pressure via generation of oxidative stress in subfornical organ (SFO) in the brain, led us to hypothesize that...
We have carried out an in-depth study of three bright-rimmed clouds SFO 11, SFO 11NE and SFO 11E associated with the HII region IC 1848, using observations carried out at the James Clerk Maxwell Telescope (JCMT) and the Nordic Optical Telescope (NOT), plus archival data from IRAS, 2MASS and the NVSS. We show that the overall morphology of the clouds is reasonably consistent with that of radiati...

Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous environmental pollutants and well-known carcinogens. Hydroxy derivatives of PAH are considered as biomarkers of PAH exposure, and there is a need to measure these metabolites at low concentrations. So, a precise and eco-friendly analytical method has been developed for rapid determination of PAH metabolites. For the first time, a new analyt...
Adipsic hypernatremia is a rare disease presenting as persistent hypernatremia with disturbance of thirst regulation and hypothalamic dysfunction. As a result of congenital disease, tumors, or inflammation, most cases are accompanied by structural abnormalities in the hypothalamic-pituitary area. While cases with no hypothalamic-pituitary structural lesion have been reported, their etiology has...
