Animal models and in vitro culture systems have been studied regarding cellular interactions between probiotics and pathogens or relevant host cells, though the underlying molecular mechanisms mediating the beneficial effects have not yet fully discovered. Hence, more evidence based studies are warranted to correlate whether probiotics through multiple mechanisms might indeed provide a strain-specific protection against parasites to use it as therapeutics. This article has described the effect of probiotics in some of the intestinal as well as non-gut parasites and suggested the scope of exploring the benefit for protozoan parasite Leishmania, as India is planning for the elimination of the disease.展开更多

The tensile strained Ge(1-z)Cz on Si(1-x-y)GexSny heterostructure provides a direct band gap type I configuration. The transmission coefficient and tunneling current density have been calculated considering single and multiple quantum wells. A comparative study of tunnelling current of the proposed structure is done with the existing RTD structure based on GeSn/SiGeSn DBH. A higher value of the current density for the proposed structure has been obtained.展开更多
