nowadays apphcanon of nanotubes in biology and medicinal science is more investigated. nanotubes can passthroueh cell walls and transport and release drugs in special tissues. the purpose of this paper is to investigatethe interaction of a nanotube having hydroxyl functional groups (oh) with an anticancer agent. in this worktransporting of an anticancer drug named 2-(2-amino 6,7-dimethyl pterid...

methanol extract of dried leaves of momordica charantia linn ( cucurbitaceae ) was investigated for anxiolytic, antidepressant and anti-inflammatory activities in animal models. anxiolytic activity of methanol extract of dried leaves of momordica charantia linn was tested by elevated plus maze test and the results showed a significant anxiolytic effect comparable, with diazepam in all the teste...

background and objectives: salvia chloroleuca rech. f. & allen., is an endemic species growing wildly in north east and center parts of iran but there is no information about its safety. to provide information about the safety of the species, we evaluated its acute and sub chronic toxicity in rats. methods: in acute toxicity study, the aqueous methanol (80%) extract at a single dose of 2000...

New bionanocomposite proton exchange membranes were prepared from sulfonated polybenzimidazole (s-PBI) and various amounts of sulfonated ZnO/cellulose nanohybrids (ZnO/cellulose-SO3H). The use of ZnO/cellulose-SO3H compensates for the decrease in ion exchange capacity of membranes observed when non-sulfonated nano-fillers are utilized. The strong –SO3H/–SO<su...

Recent studies suggest that infrared dark clouds (IRDCs) have the potential of harboring the earliest stages of massive star formation and indeed evidence for this is found toward distinct regions within them. We present a study with the Plateau de Bure Interferometer of a core in the archetypal filamentary IRDC G11.11-0.12 of a few arcsecond resolution to determine its physical and chemical st...

The subject of this study was to optimize the transesterification parameters biodiesel produced from sword bean (C. gladiate) using Response Surface Methodology (RSM). Four (Reaction temperature 55 0C, Catalyst concentration 0.4 wt%, Methanol oil ratio 4:1 and reaction time 60 min) were optimized. Data obtained revealed that optimum conditions for C. gladiata seed resulted in 92.88% yield. Mult...

The CH3 + OH bimolecular reaction and the dissociation of methanol are studied theoretically at conditions relevant to combustion chemistry. Kinetics for the CH3 + OH barrierless association reaction and for the H + CH2OH and H + CH3O product channels are determined in the high-pressure limit using variable reaction coordinate transition state theory and multireference electronic structure calc...

abstract an investigation was undertaken to ascertain the influence of hydro-alcoholic solutions on plant growth as well as quality attributes of strawberry fruits. the mother plants of strawberry (fragaria ananasa cv. gaviota) were subjected to various aqueous solutions of ethanol (15, 30%), methanol (15, 30%) and the mixture of ethanol + methanol (15 or 30%) plus the control (water only) as f...

We report a theoretical study of the first silver-dependent enantiodivergent gold-catalysed reaction. The combination single chiral binuclear gold(I) chloride complex and silver perchlorate catalyses asymmetric intramolecular hydroamination alkenes affords both enantiomers products by applying simple solvent change from toluene to methanol. A gold-silver adduct that occurs only in methanol appe...
