Identification of essential oil phytocompounds as natural inhibitors of Odorant-binding protein to prevent malaria through approach.

Malaria predominantly affects millions annually in the African and Asian tropical and subtropical countries. With no effective vaccine, malaria prevention is exclusively dependent on preventing human-vector interaction. , the main vector of the malaria parasite contains Odorant Binding proteins (OBPs) which are considered an attractive drug target for anti-malarial therapy.

Highly selective and sensitive coumarin-triazole-based fluorometric 'turn-off' sensor for detection of Pb ions.

Exposure to even very low concentrations of Pb is known to cause cardiovascular, neurological, developmental, and reproductive disorders, and affects children in particular more severely. Consequently, much effort has been dedicated to the development of colorimetric and fluorescent sensors that can selectively detect Pb ions. Here, we describe the development of a triazole-based fluorescent sensor L5 for Pb ion detection.

Dimensional changes in the Kolahoi glacier from 1857 to 2014.

This study assimilates data from historical records (1857-1961/84), survey of India topographic maps, and a series of multispectral satellite data (1962-2014) for analyzing the shrinkage and dimensional changes of the Kolahoi glacier, Jammu and Kashmir, between 1857 and 2014. The composite results show that the glacier has receded by ∼3423 m (21.8 m/year) in the past 157 years.

Landmark-based geometric morphometric analysis of wing shape among certain species of Aedes mosquitoes in District Dehradun (Uttarakhand), India.

Background & Objectives: Insect wing morphology has been used in many studies to describe variations among species and populations using traditional morphometrics, and more recently geometric morphometrics. A landmark-based geometric morphometric analysis of the wings of three species of Aedes (Diptera: Culicidae), viz. Ae.

Dipterous haematophagous insects occurring in Dehradun district and its adjoining areas in Uttarakhand, India.

Haematophagous dipterans belonging to 10 genera - Aedes (12), Anopheles (14), Armigeres (01), Culex (09), Toxorhynchites (01), Uranotaenia (01), Sergentomyia (02), Phlebotomus (01), Atylotus (01) and Tabanus (03) were encountered from 12 localities under 6 blocks of Dehradun district (Uttarakhand) during January 2011 to December 2012. The Culicines (50.69%) were more dominant than the Anophelines (38.

Occurrence of a Snail Borne Disease, Cercarial Dermatitis (Swimmer Itch) in Doon Valley (Uttarakhand), India.

Background: 'Cercarial dermatitis' also known as swimmers itch (Skin allergies) is caused by a trematode parasite, Schistosoma which has two hosts - an invertebrate (snail) and a vertebrate (livestock, human being). Although the availability of both vector snails and pathogens at the selected site the Doon Valley in northern India has already been confirmed but there was a hazy picture of the disease, whether it is due to entrance of cercariae or due to wild variety of grass (Parthenium hysterophorus). The present study is an attempt to provide a way forward towards the vector snails and snail borne diseases in the study area.
