Many species of tea (Camellia sinensis) and cowslip (Echium amoenum) are used in Iranian traditional medicine. The aim of this study was to conduct the survey on the ability of Iranian black tea and cowslip extracts on secretion of tumor necrosis factor-alpha (TNF-alpha) by non-infected and infected mouse macrophages. A macrophage infection model with Legionella pneumophila and enzyme linked im...

A protocol was developed for callus induction and regeneration in tomato (Lycopersicon esculentum) var. Moneymaker. Hypocotyl and leaf disc explants of tomato were used as a starting material for callus induction. Explants were cultured on MS medium having different concentrations of hormones. Maximum callogenesis from hypocotyls was obtained on MS medium supplemented with IAA (2 mg/l), NAA (2 ...

background. the most common species isolated from primary endodontic infections are black-pigmented bacteria. these species are implicated in apical abscess formation due to their proteolytic activity and are fastidious in nature. therefore, the present study was carried out to evaluate the presence and identification of various pigmented porphyromonas and prevotella species in the infected roo...

Plasmodium falciparum erythrocyte membrane protein 1 (PfEMP1) proteins expressed on the surface of P. falciparum-infected erythrocytes undergo antigenic variation by switching the gene expressed within a repertoire of approximately 50 var genes per haploid genome. The switching of PfEMP1 plays an important role in the survival and pathogenesis of the parasite. To understand how a parasite switc...

The tissue culture derived sugarcane var. CoJ 64 plants attained better height, millable cane height and a greater number of live buds to conventionally raised plants. Further, the plants raised in vitro showed 13.2% increase in cane yield and 11.03% sugar recovery as compared to conventionally propagated sugarcane under parallel agronomic practices in the field, advocating suitability of seed ...
