Abstract The present study was carried to evaluate antibacterial activity of water extracts of honey against some selected bacteria (Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae and pseudomonas aeruginosa) using microdilution method (MIC) at different concentrations (100-0.195mg/ml) and well diffusion method (200 mg/ml). The inhibitory potency of the honey from different sources varied on the test […]
Formation and phase transition enthalpies for N-dymethylglycolurils
Abstract Combining quantum chemical thermochemistry and experimental data from literature, a series of thermochemical parameters (ΔsolvHθ; ΔcrgHθ; ΔcrlHθ; ΔlgHθ; ΔfgHθ; ΔflHθ; ΔfcrHθ; Cv and Cp) were obtained for 2,4-dimethylglycoluril (2,4-DMGU), 2-6-dimethylglycoluril (2,6-DMGU) and 2,8-dimethylglycoluril (2,8-DMGU). Keywords Computational thermochemistry, Formation enthalpies, 2,4-dimethylglycoluril, 2-6-dimethylglycoluril, 2,8-dimethylglycoluril. Google Scholar Citation [Full Text: PDF]

Adsorptive removal of Bisphenol A from aqueous solutions by Pistacia atlantica: isotherm and kinetic Studies
Abstract The aim of this study is to investigate the possibility of Pistacia atlantica Biomass as an alternative adsorbent for Bisphenol A (BPA) removal from aqueous solution. The effect of various parameters including contact time, solution pH, adsorbent dosage and Bisphenol A concentration was investigated in this experimental-lab study, Also, the isotherm and kinetic studies […]
Method Development and Validation for Simultaneous Estimation of Lamivudine and Zidovudine by RP-HPLC
Abstract A new, accurate, rapid and effective isocratic reverse-phase high performance liquid chromatographic (RP-HPLC) method was developed, optimized and validated for the estimation of Lamivudine (LAM) and Zidovudine (ZID) in bulk and pharmaceutical dosage forms. The drugs were estimated using Shiseido C18 (250 mm x 4.6 mm, 5 µm particle size) column. A mobile phase […]
Production of Cephalosporin C from Acremonium chrysogenum, and its Antimicrobial Activity against Some Pathogenic Bacteria
Abstract The Production of cephalosporin C by Acremonium chrysogenumin flask contain fermentation medium, after that its extraction, purification and estimation was performed by Spectrophotometric Method. The antimicrobial activities of both the crude and purified cephalosporin C were performed against the test organisms by Agar Well Diffusion Method. Agar well diffusion method and the inhibition zones […]
Antibacterial and Anatomical Study of Capparis decidua L. from Different Localities of District Bhimber Azad Jammu and Kashmir, Pakistan
Abstract The plant Capparis decidua L. belongs to family Capparidaceae and its stem and fruit were extracted successively with four organic solvents viz. petroleum ether, chloroform, ethanol, and distil water. These crude extracts were assessed for antibacterial activity against two gram positive bacteria i.e. Staphylococcus aureus and Bacillus subtilus and two gram negative bacteria i.e. […]
Selective s-alkoxycarbonylation of isomeric 5-pyridyl-1,3,4-oxadiazoles and antimicrobial activity of the synthesized compounds
Abstract Selective S-alkoxycarbonylation of isomeric – 5-(2-pyridyl)- (1), 5-(3-pyridyl)- (2), and 5-(4-pyridyl)-1,3,4-oxadiazol-2-thiones (3) have been studied and novel series of S-substituted derivatives (7-15) have been synthesized and characterized by physical methods of research. No formation of the amides – N-substituted derivatives (A) was observed. The antimicrobial tests indicated that the 2-alkyloxycarbonylthio-oxadiazole derivatives exhibited a remarkable […]
Control of erwinia spp. isolated from star-of-bethlehem (ornithogalum spp.) using actinomycetes and antiserum prepared from the bacteria using rabbit
Abstract Erwinia spp. causes soft rot in Ornithogalum spp., a flower grown purposely for export in Kenya. As a result the pathogen pauses a great risk to the economy of the country. This study aimed at isolating actinomycetes and Erwinia spp. from the soils of Menengai crater and infected Ornithogalum spp. respectively. In addition, the […]
