The effects of intraperitoneal injections of various doses of A9-tettahydrocannabinol (A”-THC) on brain levels of cyclic adenosine 3’,5’-monophosphate (cyclic AMP) have been studied in mice. Doses of A9-THC in the range of 0.1 to 1.0 mgikg cause a 5&160 per cent elevation of cyclic AMP levels compared to controls (P < O.OOOS), while doses of A9THC in the range of 2.0 to 10.0 mg/kg cause a 3@-60...
Functional organic dyes play a key role in many fields, namely biotechnology and medical diagnosis. Herein, we report two novel 2,3- 3,4-dihydroxyphenyl substituted rosamines (3 4, respectively) that were successfully synthesized through microwave-assisted protocol. The best reaction yields obtained for rosamine which also showed the most interesting photophysical properties, specially toward b...
This study was amid to biogenic synthesis of Silver Nanoparticles (AgNPs) and evaluated its chemical-physical biomedical properties. The currently used reducing agent is Polyalthia sclerophylla (CEPS). As a reducer, crude extract leaves (CEPS) used, while silver nitrate (AgNO3) as an initiator. Two samples were prepared named AgNPs-a AgNPs-b, respectively. carried out characterize their biologi...
Biogenic Mn oxides exert important controls on trace metal cycling in aquatic and soil environments. A Mn-oxidizing bacterium Bacillus sp. WH4 was isolated from Fe-Mn nodules of an agrudalf in central China. The biogenic Mn oxides formed by mediation of this Mn oxidizing microorganism were identified as short-ranged and nano-sized Mn oxides. Cd adsorption isotherms, pH effect on adsorption and ...
Variation of hydrochemical conditions, with special reference to adequacy of waters as fish habitats, was traced based on selected hydrochemical parameters obtained during the studies conducted from February 2013 till February 2014 year. The results were compared with earlier studies. The sources of organic pollution were identified, and the effect of biogenic substances on the biomass, as well...
