The postnatal ontogeny of [t25I]a-bungarotoxin (a-Btx) binding distribution in rat neocortex was described and quantified using autoradiography of in vitro labeled brain sections. During the first two weeks, distinctive transitory radial and laminar patterns emerged. Dense columnar bands of a-Btx binding extended through the depth of primary sensory cortex, including somatosensory, visual and a...
ABSTRACT. One-pot, mild and efficient synthesis of various spiro-nitrogen heterocycle compounds, based on the reaction ninhydrin 1,2-diamino-benzene, (indenoquinoxalin), with N-heterocycle compounds dialkylacetylenedicarboxylates is described. Using this approach, at a temperature 50-60 °C in acetonitrile solvent, can be obtained very high yields.

A novel conotoxin, kappa-conotoxin (kappa-BtX), has been purified and characterized from the venom of a worm-hunting cone snail, Conus betulinus. The toxin, with four disulfide bonds, shares no sequence homology with any other conotoxins. Based on a partial amino acid sequence, its cDNA was cloned and sequenced. The deduced sequence consists of a 26-residue putative signal peptide, a 31-residue...
this study investigated the potential role of age in inductive and deductive grammar learning among iranian foreign language learners. the experimental population consisted of our randomly selected samples including two groups of children (with age of exposure to english within 8-13), and two groups of adults (with age of exposure to english within 11-13). thus, the comparison was between ch...
despite the different criticisms on contrastive analysis it has been proved that the results of it(when processed) can be useful in a tefl environment, specially at the level of phonology.this study is an attempt to compare and contrast the sound systems of kurdish and english for pedagogical aims.the consonants,vowels,stress and intonation of the two languages are described by the same model...
Removal of benzene, toluene, and xylenes (BTX) from waste gases was studied in a 50-L laboratory-scale biofilter (25.2 cm I.D. and 100 cm H). A commercial blend of composted chicken manure and peat moss was used as the filter bed. The composted organic material was selected due to its relatively high microbial diversity and for its nutritive value (i.e. presence of N-sources and essential miner...
The anticonvulsants phenytoin and carbamazepine interact allosterically with the batrachotoxin binding site of sodium channels. In the present study, we demonstrate an autoradiographic technique to localize the batrachotoxin binding site on sodium channels in rat brain using [3H]batrachotoxinin-A 20-alpha-benzoate (BTX-B). Binding of [3H]BTX-B to brain sections is dependent on potentiating allo...
A series of quinoxaline-based compounds 1–4 have been synthesized by Palladium-Catalyzed cross-coupling reaction and their photophysical properties extensively studied. Compounds show deep blue light emission both in solution (λem ≤ 425 nm, CIEy≤0.03) solid-state. Moreover, 1–3 a non-typical aggregation-induced enhanced (AIEE), which would be effective light-emitting materials. The DFT calculat...
The current work is aimed at the experimental investigation of the aldehyde and BTX (benzene, toluene and Xylene) pollutants emitted from a light duty spark ignition (SI) vehicle fueled on gasoline and ethanol-gasoline blended fuel, operating with a three-way catalytic converter (TWC). At the same time, the specific reactivity (SR) of these pollutants has also been addressed in this paper. The ...
