Warm sensitive neurons (WSN) play a major role not only in body temperature regulation, but also in sleep regulation. The present study was undertaken to investigate the role of WSN of the preoptic area (POA) in mediating the ambient temperature (T(amb)) related changes in sleep. The effect of T(amb) changes on sleep and body temperature was studied in rats before and after destruction of WSN o...

citrus blast is one of the important diseases of citrus in north of iran. the disease causes considerable damage during and immediately after the cold seasons. the causal agents have epiphytic survival on diverse weeds during spring and summer. during 2009-2010, samples were collected from several candidate weed plants including: poa annua, phalaris canariensis, sorghum halepense, cynodon dacty...

Plants relict origin also found: Poa nemoralis L., compressa Ulmus glabra Huds., Parietaria chersonensis (Lang & Szov.) Dörfl., Asparagus verticillat...

The aim of this study was to evaluate the biodiversity ofplant associations in On Ebn-e-Ali Mountain in Tabriz and its relationship to various biodiversity indices. Four plant associations including 1) Noaea mucronata- Poetum bulbosa, 2) Noaea mucronata- Brometum tomentellus, 3) related to bush form as well as Poeto bulbosa-Brometum tomentellus and4) Brometo ...

Lipopolysaccharide (LPS) administration induces hypothalamic nitric oxide (NO); NO is antipyretic in the preoptic area (POA), but its mechanism of action is uncertain. LPS also stimulates the release of preoptic norepinephrine (NE), which mediates fever onset. Because NE upregulates NO synthases and NO induces cyclooxygenase (COX)-2-dependent PGE(2), we investigated whether NO mediates the prod...

In this study, we formulate positive and negative externalities caused by changes in the supply of shared vehicles as ride sharing games. The study aims to understand the price of anarchy (PoA) and its improvement via a coordination technique in ride sharing games. A critical question is whether ride sharing games exhibit a pure Nash equilibrium (pNE) since the PoA bound assumes it. Our result ...
