Malaria is transmitted by Anopheles stephensi and for controlling the malaria parasite Plasmodium spp., the vector mosquito has to be controlled. Extensive use of synthetic and chemical insecticides has resulted in environmental hazards and also in development of physiological resistance among vector mosquito species. Plant products are considered to be a potential alternative approach as they ...

This study investigated proteomic changes occurring in Anopheles gambiae and Anopheles stephensi during adult mosquito aging. These changes were evaluated using two-dimensional difference gel electrophoresis (2D-DIGE) and the identities of aging related proteins were determined using capillary high-pressure liquid chromatography (capHPLC) coupled with a linear ion-trap (LTQ)-Orbitrap XL hybrid ...

Clostridium bifermentans serovar malaysia (C.b.m.) is highly toxic to mosquito larvae. In this study, the following aquatic nontarget invertebrates were treated with high C.b.m. concentrations (up to 1,600-fold the toxic concentration for Anopheles stephensi) to study their susceptibility towards the bacterial toxin: Planorbis planorbis (Pulmonata); Asellus aquaticus (Isopoda); Daphnia pulex (C...

The sociology of professions literature would predict that the contemporary state would not allow groups to continue unregulated or unreformed. However, this is indeed the case with the UK veterinary profession, with legislation dating back to 1966. Using an interdisciplinary analysis of published literature and reports, this paper assesses whether wider social, political and ethical dynamics c...

There are many approaches that need to inform education systems around the world. It also matters to know whether policymakers have followed (for example), a socialist or an individualist approach in formulating an education system. Furthermore, teachers and other role-players need to understand the paradigm that undergirds their system of education. This article focuses on the ideas of Stephen...

Windkessel and similar lumped models are often used to represent blood flow and pressure in systemic arteries. The windkessel model was originally developed by Stephen Hales (1733) and Otto Frank (1899) who used it to describe blood flow in the heart. In this paper we start with the onedimensional axisymmetric Navier-Stokes equations for time-dependent blood flow in a rigid vessel to derive lum...

background : mosquitoes transmit serious human diseases, causing millions of death every year. 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. nine different locally available medicinally important plants suspected to posse larvicidal property w...

b a ckground: we aimed to extract the ingredients from leaves of gossypium hirsutum (bt cotton) using different solvents and evaluate for potential use to control different larval stages of mosquito species, aedes aegypti and anoph eles stephensi . m e t hods: qualitative and quantitative estimation of ingredients from go. hirsutum (bt) plant extract was carried out and their inhibitory action ...

BACKGROUND & OBJECTIVES Anopheles stephensi, an important vector of malaria continues to be distributed widely in the Indian subcontinent. The natural vigour of the species combined with its new tolerance, indeed resistance to insecticides has made it obligatory that we look for control methods involving genetic manipulation. Hence, there is an immediate need for greater understanding of the ge...

Malaria remains a major public health problem due to the emergence and spread of Plasmodium falciparum strains resistant to chloroquine. There is an urgent need to investigate new and effective sources of antimalarial drugs. This research proposed a novel method of fern-mediated synthesis of silver nanoparticles (AgNP) using a cheap plant extract of Pteridium aquilinum, acting as a reducing and...
