Based on experiments showing immunomodulatory effects of garlic (Allium sativum L.), we sought to see whether Allium hirtifolim Boiss., belonging to the same genus of garlic, has any effect on immune responses. Hydroalcoholic extract and polyphenolic fraction of A. hirtifolium bulbs were prepared. Allicin (diallyl thiosulfinate), a biologically active component, was identified in plant bulbs...
the japanese and english white quails are widespread strains and belongs to the galliformes order, phasianidae family, coturnix genus and japonica species. these birds are likely to be well-adapted to the hard conditions and resistance to diseases as it has attained economic importance as an agricultural species. in the current study, the genetic variation of japanese and english white quail ...
In Tanzania, a large amount of domestic and industrial wastes are daily released to the aquatic environment without prior treatment. The demographic pressure resulting from the about 2.5 million people in the Dar es Salaam region (according to the 2002 National Census) is the major driver of amounts of waste released. Heavy metals such as arsenic (As), cadmium (Cd), cobalt (Co), chromium (Cr), ...
Background and Aim: Dental Amalgam is a common restorative material for posterior teeth. Because of Hg content in the composition of amalgam, during the handling of material, mercury may release as vapor in the environment. Excess amount of mercury vapor can cause serious health problems in dental personnel. The aim of this investigation was to determine mercury vapor concentration in working e...
Dye compounds are the important contaminants of the environment. The dyes are often toxic, carcinogenic and mutagenic and can led to allergies and skin problems. Thus, the dye contaminants should be treated before discharge to environment. The aim of this study was the evaluation of efficacy of Cuttle fish bone powder for the removal of Reactive Red 198 dye from aqueous solution and...

background : glioblastoma multiforme (gbm) or grade iv astrocytoma is the most common and lethal adult malignant brain tumor. several of the molecular alterations detected in gliomas may have diagnostic and/or prognostic implications, proteomics has been widely applied in various areas of science, ranging from the deciphering of molecular pathogen nests of discuses. method: we extracted protein...
Indelible marking of pink bollworm (Pectinophora gossypiella) would assist in implementation of sterile insect technique-based pest control of this insect. Additionally, genetic manipulation through DNA-mediated genetic transformation also requires a reliable genetic marker. To this end, we injected DNA plasmids encoding the enhanced green fluorescent protein gene into pink bollworm pre-blastod...
