Leaves of Artemisia annua linn. and Azadirachta indica were extracted in petroleum ether and hexane respectively by different methods of extraction i.e. cold extraction, reflux extraction and soxhlet extraction. The crude extract obtained was tested against third instar larvae of Anopheles stephensi. On comparison of larval mortality of crude extract obtained by these three methods, both soxhle...

Cyclohexanone (C6H10O, CAS No. 108-94-1) is a colorless oily liquid obtained through the oxidation of cyclohexane or dehydrogenation of phenol. It is used in the manufacture of adhesives, sealant chemicals, agricultural chemicals, paint and coating additives, solvent, electrical and electronic products, paints and coatings, photographic supplies, film, photochemicals, and as an intermediate in ...

OBJECTIVES To test the activity of two copper-based biocides, CuAL42 and CuWB50, and benzalkonium chloride against 169 isolates of methicillin-resistant Staphylococcus aureus (MRSA) pulsotype USA300, a virulent, multiply resistant, widespread clone in the USA. METHODS Tests including MIC, MBC and time-kill studies were performed multiple times. RESULTS The MIC range, MIC(50) and MIC(90) (0....

Three experiments involving 296 pigs were conducted to determine the related effects of copper sulfate and ferrous sulfide on performance and liver copper and iron stores of growing-finishing pigs, and the effect of ferrous sulfide on the depletion of copper from the liver. The dietary addition of 250 ppm copper alone improved growth rate by 9.2% (621 vs 678 g/day) and feed to gain ratio by 3.3...

Fumonisin B1 (FB1) is a mycotoxin isolated from Fusarium fungi that contaminate crops worldwide. A previous study demonstrated that FB1 promoted preneoplastic foci in initiated rats and induced hepatocellular carcinomas in BD IX rats at 50 parts per million (ppm), but fundamental dose-response data were not available to assist in setting regulatory guidelines for this mycotoxin. To provide this...

the effect of lavender essential oil (leo) on broiler performance, carcass characteristics and blood metabolites was examined in a completely randomized design with 5 treatments (control diet, virginiamycin 10% (50 ppm) and 3 diets containing 150, 250, 350 ppm lavender essential oil) and 5 replications in a period of 42-days. no significant differences were noticed for feed intake between the t...

In this work, the phytoremediation potential of 2,4-Dichlorophenol (2,4-DCP) from soil and wetlands by Datura stramonium L. (jimsonweed) was investigated. The medium seedlings growing in a hydroponic system adjusted to different concentrations (0.0, 75, 100, 125, 150, 175, 200, 225, 250 275 ppm) 2,4-DCP. Four days later, remediation rate 2,4-DCP growth medium, root-stem length, dry weight, lipi...

This article reports the inhibitory effects of phosphonated chitosan (PCH, synthesized from chitosan (CHS) by a Mannich-type reaction) on the in vitro silicic acid condensation. In particular, the ability of PCH to retard silicic acid condensation in aqueous supersaturated solutions at circumneutral pH is studied. Furthermore, the effect of anionic carboxymethyl inulin (CMI) polyelectrolyte on ...

We evaluated the lethal effects of household bleach (5.25% sodium hypochlorite; NaOCI) on immature Aedes aegypti in tap water, with and without food, and in field-collected automobile tires. A sublethal dose was employed as a disinfectant in tires to control immatures through the destruction of microorganisms that constitute the main food items of mosquito larvae. The concentration of bleach th...

Isolation and identification of secondary metabolite compound from chloroform fraction of Usnea longissima and its bioactivity test as an antibacterial had been conducted. The isolation of the chemical compound was performed by using Gravity Column Chromatography (GCC) and ThinLayered Chromatography (TLC). The result showed the needle crystal shaped isolated compound with translucent white colo...
