Nanoscale technologies have gone from being just an ambitious concept to being a rapidly advancing area of interdisciplinary science with immense practical importance. Feynman's vision on nanoscience provided great impetus to the development of nanophysics, nanochemistry, nanoelectronics and nanotechnology in general [1]. High resolution microscopic devices(More)
Grasserie, a polyorganotrophic disease caused by Bombyx mori nucleopolyhedrovirus (BmNPV), accounts for lethal infection to fifth instar silkworm larvae. It was found that nanoparticle (NP)-induced morphological transformation of BmNPV polyhedra could reduce the infectivity of BmNPV both in cell line and in silkworm larvae. Initially, 11 NPs were screened(More)
Objective. To determine the level of knowledge, opinions, and preventive practices followed by dental students against Hepatitis B. The study also explored if any correlation existed between knowledge, opinion, and preventive practices score. Materials and Methods. A cross-sectional study was conducted in a dental teaching institution. The subjects(More)
Objective. To assess the prevalence of oral potentially malignant disorders and to determine the potential risk factors for its development in Indian population. Materials and Methods. This cross-sectional study was carried out on 1241 individuals in Indore, Madhya Pradesh. A questionnaire was designed to record information about sociodemographic(More)
Chloroform–methanol plant lipid extracts of 19 Indian medicinal plants from 15 plant families were screened for feeding deterrence, contact toxicity and fumigant toxicity properties on grain weevil Sitophilus oryzae L. (Coleoptera: Curculionidae). Fifteen Indian medicinal plant derived lipids showed weak to strong antifeedant activities against S. oryzae at(More)
Nowadays gold nanoparticle (GNP) is increasingly being used in drug delivery and diagnostics. Here we have reported a comparative analysis of detailed stability and toxicity (in vitro and in vivo) profile of three water soluble spherical GNPs, having nearly similar size, but the surfaces of which were modified with three different capping materials aspartic(More)
Surface modified amorphous nanoporous silica molecules with hydrophobic as well as hydrophilic character can be effectively used as therapeutic drug for combating chicken malaria in poultry industry. The amorphous nanosilica was developed by top-down approach using volcanic soil derived silica as source material. Amorphous silica has long been used as feed(More)
Various types of surface functionalized nanosilica (50-60 nm size with 3-10 nm inner pore size range) have been used to kill insect pests by sucking up cuticular lipids and breaking the water barrier 1,2. We have also utilized nanosilica for mopping up host lipids induced by the malarial parasite, P. gallinaceum in poultry birds; VLDL cholesterol and serum(More)
Malaria and other parasites, including virus often induce an increase in host lipids which the invaders use to their own advantage. We obtained encouraging results in our investigations on bird malaria with a new approach namely the use of nanosilica to mop up excess host lipids 1, 2. While this project is continuing we have investigated another, simpler(More)
Wild animals, pets, zoo animals and mammals of veterinary importance heavily suffer from trypanosomiasis 1. Drugs with serious side effects are currently mainstay of therapies used by veterinarians. Trypanosomiasis is caused by Trypanosoma sp. leading to sleeping sickness in humans. Surface modified (hydrophobic and lipophilic) amorphous nanoporous silica(More)
