conclusions genome instability in addicted patients was demonstrated in this study. controversially, considering incoherent results of previous studies and our data, more studies in longer duration of methadone use are needed to elucidate the consequence. results the mutagenicity index in addicted group was robustly higher than healthy volunteers. fortunately, this significant difference was lo...

b a ckground: anoph eles culicifacies, a major malarial vector has been recognized as a complex of five sibling species, a, b, c, d and e. these sibling species exhibit varied vectorial capacity, host specificity and susceptibility to malarial parasites/ insecticides. in this study, a pcr assay developed earlier for distinguishing the five individual species was validated on samples of a n . cu...

the co-inoculation of mulberry with phosphate solubilizing micro-organisms, nitrogen fixing bacteria and arbuscular mycorrhiza has influenced its macronutrient uptake through leaf. the data revealed that maximum nitrogen (484.12 kg /ha) , phosphorus (59.83 kg /ha) and potassium (244.61 kg/ha) uptake through leaf has taken place due to co-inoculation treatments as compared to the un inoculated t...

conclusions therefore the non-infectious dlps were became infectious if introduced into the cytoplasm of permissive and cancerous cells, without passing attachment and entry process. results we attempt to avoid the attachment and entry of the rotavirus by using lipofectamine to mediate the delivery of viral particles directly into the cytoplasm. dlp was endocytosed into the cytoplasm following ...

Bioactive compounds from plants play an important role in slowing many neurodegenerative diseases, such as Alzheimer’s disease, by inhibiting cholinesterase enzymes. Studies have shown that oxidative stress is associated with the development of disease. In traditional medicine Bosnia and Herzegovina, Teucrium montanum used to treat numerous diseases. The chemical composition biological activity...
