Highly stable nanoparticles of metallic silver with average dimension of 26.6 nm were synthesized by a simple, cost-effective, reproducible and previously unexploited biogenic source viz. dried green fruits of Drypetes roxburghii (Wall.) (common name putranjiva). The as-synthesized silver nanoparticles (Ag NP) were characterized by their characteristic(More)
Mosquitoes act as a vector for most of the life threatening diseases like malaria, yellow fever, dengue fever, chikungunya ferver, filariasis, encephalitis, West Nile Virus infection, etc. Under the Integrated Mosquito Management (IMM), emphasis was given on the application of alternative strategies in mosquito control. The continuous application of(More)
BACKGROUND Vector control is facing a threat due to the emergence of resistance to synthetic insecticides. Insecticides of botanical origin may serve as suitable alternative biocontrol techniques in the future. Although several plants have been reported for mosquitocidal activity, only a few botanicals have moved from the laboratory to field use, because(More)
Parkinson disease (PD) is second only to Alzheimer disease as the most common human neurodegenerative disorder. Despite intense investigation, no interdictive therapy is available for PD. Recent studies indicate that both innate and adaptive immune processes are active in PD. Accordingly, we found a rapid increase in RANTES (regulated on activation normal T(More)
BACKGROUND Mosquitoes are associated with the transmission of malaria, dengue, Japanese encephalitis, filariasis and other viral diseases throughout the globe, apart from being a nuisance pest. Biological control alone or as a part of integrated vector management stands to be a better alternative to the chemical controls aimed against pest mosquitoes. At(More)
Dregea volubilis (family Asclepediaceae) is widely used as anthelmintic in traditional system of medicine in eastern and southern part of India. The aim of this study was to evaluate the anthelmintic activity of the methanol extract of D. volubilis leaves (MEDV) and to observe its effect through SEM study. Live parasites (trematode Paramphistomum(More)
Bombax malabaricum (family Bombacaceae) is used as anthelmintic in traditional system of medicine in Southern Punjab of Pakistan. The objective of this study was to evaluate the anthelmintic activity of the methanol extract of B. malabaricum leaves (MEBM). Live parasites (trematode: Paramphistomum explanatum) were collected from buffalo in 0.9%(More)
BACKGROUND Problems associated with resistant mosquitoes and the effects on non-target species by chemicals, evoke a reason to find alternative methods to control mosquitoes, like the use of natural predators. In this regard, aquatic coleopterans have been explored less compared to other insect predators. In the present study, an evaluation of the role of(More)
Lymphatic filariasis, caused by Wuchereria bancrofti, Brugia malayi and B. timori is a public health problem of considerable magnitude of the tropics and subtropics. Presently 1.3 billion people are at risk of lymphatic filariasis (LF) infection and about 120 million people are affected in 83 countries. In this context it is worth mentioning that 'nature'(More)
Snake venom contains a diverse array of proteins and polypeptides. Cytotoxins and short neurotoxins are non-enzymatic polypeptide components of snake venom. The three-dimensional structure of cytotoxin and short neurotoxin resembles a three finger appearance of three-finger protein super family. Different family members of three-finger protein super family(More)
