Neurokinin 3 receptors (NK3-Rs) are expressed in the supraoptic nucleus (SON), and SON is innervated by substance P (SP)-expressing A1 neurons in the medulla. Because SP stimulates vasopressin (VP) and oxytocin release from explants of the hypothalamo-neurohypophyseal system (HNS), two hypotheses were tested: (1) SP-stimulated VP release is mediated by NK3-Rs, and (2) stimulation of the A1 path...

Bacillus Sp. was isolated near the mining area and was studied for biosorption U and Th. This study presents uptake of uranium (U) and thorium (Th) by live and dead cells of Bacillus Sp. Increasing concentration of U and Th showed decrease in absorption by Bacillus Sp. Dead cells of Bacillus Sp. exhibited same or more uptake of U and Th than living cells. Increasing temperature promotes uptake ...

bacillus sp. sbs25, a gram positive bacteria isolated from soil was found to be effectivein the biodegradation of natural rubber latex. the products of latex biodegradation were separated from the ether extract by thin layer chromatography. gas chromatography and mass spectrometry showed the biodegradation of the major compound into three simpler fractions with low molecular weights. this was f...

The present study assessed the effect of seed inoculation with single or multiple plant growth-promoting rhizobacterial (PGPR) strains on yield in spring wheat (Triticum aestivum spp. vulgare var. Kırık) and barley (Hordeum vulgare cv. Tokak) plants in both greenhouse and field conditions during the years 2007 and 2008. The treatments of wheat and barley plants during the first year include...

in order to evaluate the effects of different plant growth promoting rhizobacteria (pgpr) on yield and yield components of sesame, an experiment was conducted in the form of randomized complete block design with three replications at research station, faculty of agriculture, ferdowsi university of mashhad in year 2009. treatments were: 1) nitragin (containing of azotobacter sp., azospirillum sp...

Substance P (SP) is a widely distributed neuropeptide that works as a neurotransmitter and neuromodulator. Recently, SP receptors, particularly neurokinin-1 receptors (NK(1)-Rs) that have a high affinity for SP, have been observed not only in neuron and immune cells, but also in other peripheral cells, including bone cells. To identify the role of SP in bone formation, we investigated the expre...

background: atrazine is a widely used herbicide. the increasing salinity of many water resources has had a negative effect on atrazine biodegradation. the aim of this study was to isolate atrazine degrading bacteria in semi-salinity media.   methods: nine selected bacterial species were cultivated on the mineral salt broth culture medium containing atrazine (50, 100, 500 mg/l), nacl concentrati...
