Airborne biological allergens trigger an allergic response required for the development of atopic disease. Biological allergens are released into the air by wind, rain and active discharge mechanisms. In this review article an attempt has been made to evaluate the published literature on prevalence and types of air borne allergens in India. Important pollen allergens reported from India were: P...

During a 36-hour period, the rate of absorption of oxygen, respiration quotient, and rate of evolution of heat have been measured using seeds of Prosopis juliflora, Kochia scoparia, and Oxyria digyna. The results obtained in pure water were compared with those obtained in dilute solutions of dinitrolphenol. The data appear to be reproducible to +/- 10% at the end of the 36-hour period and are i...

The present paper aims to identify the distribution of Microsatellite markers (SSRs)/Single Nucleotide Polymor-phism (SNPs) as resource tools for the analysis of interspecies hypervariability in Prosopis spp. Microsatellites are ubiquitously repeated extension of 1-5 bp motif extended throughout the genome. The dbEST division of Genbank contains 1467 ESTs of Prosopis juliflora which have been u...

pollen from mesquite (prosopis juliflora) is one of the important causes of immediate hypersensitivity reactions in the arid and semi-arid regions of the world. the aim of present study is to produce and purify the recombinant form of allergenic ole e 1-like protein from the pollen of this allergenic tree. immunological and cross-inhibition assays were performed for the evaluation of ige-bindin...

This work deals with the effects of the alcoholic extracts of 15 plants (collected from the northern region of Pakistan) on isolated guinea-pig ileum preparation. Dried powdered plant material was extracted with alcohol. The extract obtained after the removal of the alcohol was triturated with pet-ether (40-60°) and then charcoaled, filtered and dried under vacuum. The isolated guinea-pig ileum...

Spatial variation in host plant availability may lead to specialization in host use and local host adaptation in herbivorous insects, which may involve a cost in performance on other hosts. We studied two geographically separated populations of the seed beetle Megacerus eulophus (Coleoptera: Bruchidae) in central Chile: a population from the host Convolvulus chilensis (in Aucó) and a population...
