Assessment of the effects of Cucumis metuliferus fruits alkaloids against Newcastle disease virus-LaSota

Plaque formation of LaSota pathogenic strain of Newcastle disease virus adapted in chick embryo fibroblast cells

In order to adapt LaSota strain of Newcastle disease virus (NDV) on chick embryo fibroblast (CEF) cells, 0.1 ml from LaSota vaccine produced in Razi vaccine and serum research institute inoculated to the CEF cells and was passaged five times in the CEF grown in Eagle’s minimum essential medium (MEM). First to third passages were blind but in fourth passage cytopathic effect of virus was observe...

Clone Purification, Characterization and Standardization of LaSota Strain for Developing a Live Vaccine against Newcastle Disease Virus

Newcastle disease (ND) is one of the most serious illnesses of chickens. Live vaccines are widely used to prevent chicken from the disease all over the world. To access the effective and potentiate ND vaccine, a homogenous subpopulation from LaSota strain was selected following cultivation of the virus on primary chicken embryofibroblast (CEF) cells. Pathogenicity indices and molecular characte...

assessment of the efficiency of s.p.g.c refineries using network dea

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...

Improving Culture Efficiency of Cucumis metuliferus Protoplasts

Although we have made great progress in developing resistance to root – knot nematodes in cucumber, no source has been created or screened to resistance to M. incognita, the main species affecting cucumber (9, 10). Resistance to M. incognita exists in horned cucumber (Cucumis metuliferus), but efforts by many research groups (including our own) to make crosses of Cucumis species with cucumber h...
