Leptospiral Infection, Pathogenesis and Its Diagnosis-A Review.

Leptospirosis is a perplexing conundrum for many. In the existing literature, the pathophysiological mechanisms pertaining to leptospirosis is still not understood in full. Considered as a neglected tropical zoonotic disease, leptospirosis is culminating as a serious problem worldwide, seemingly existing as co-infections with various other unrelated diseases, including dengue and malaria.

Utilization of gum polysaccharide of Araucaria heterophylla and Azadirachta indica for encapsulation of cyfluthrin loaded super paramagnetic iron oxide nanoparticles for mosquito larvicidal activity.

Surface engineering of super paramagnetic iron oxide nanoparticles (SPIONs) favor the tagging of any molecule or compound onto it, encapsulating them with a biopolymer make them biocompatible and favor slow release of loaded molecules. Recovery of SPIONs is easier as they obey to external magnetic field. In this study, SPIONS were used for mosquito larvicidal activity after surface engineered with oleic acid to favor the tagging of Cyfluthrin (mosquito larvicidal agent), it was then encapsulated with gum polysaccharide derived from Azadirachta indica and Araucaria heterophylla.

Preparation, characterization and utilization of coreshell super paramagnetic iron oxide nanoparticles for curcumin delivery.

In this study, super paramagnetic iron oxide nanoparticles (SPIONs) were produced by chemical co-precipitation method, then it was constructed to be a core shell nanoparticle by functionalizing with SDS, loading with curcumin and coating with a biopolymer i.e. chitosan.
