Background: Melia indica and M. azedarach (Meliaceae) are widely used in traditional medicine. These species are considered as natural pesticides. Their major compound is azadirachtin (AZD) which is considered as the marker for quality control of these species. Objective: In the present investigation, AZD content of the leaves and fruits (comprising the whole fruit, peel, pulp and seeds) of M....

Reconstructing the past variability of Arctic sea ice provides an essential context for recent multi-year sea ice decline, although few quantitative reconstructions cover the Holocene period prior to the earliest historical records 1,200 years ago. Photochemical recycling of bromine is observed over first-year, or seasonal, sea ice in so-called "bromine explosions" and we employ a 1-D chemistry...

Piriformospora indica, a member of basidiomycota is an axenically cultivable endophytic fungus which exerts plant growth promoting effects on its host plant. P. indica is known to produce α-amylase and protease. Since the organism exhibits beneficial role in plant growth promotion, achieving high biomass is immensely essential. Hence to enable the commercial production, screening of medium comp...

We report the growth promoting potential of Piriformospora indica, which is a newly discovered arbuscular mycorrhiza-like fungus. It is a facultative symbiont and unlike arbuscular mycorrhizal fungi, it can be cultured in vitro. Adhatoda vasica is a medicinal plant. Rapid proliferation of roots was recorded in A. vasica withan important root colonization estimated to 95% after 6 months. P. indi...

Oral feeding of 70% EtOH extract of Lindenbergia indica to female rats at the dose of 500 mg/kg body weight and 1000 mg / kg body weight caused significant reduction of serum cholesterol, HDL - cholesterol, triglycerides & phospholipids (P≤ 0.05 to P≤ 0.001). Where as the protein levels were not reduced significantly.Fertility test showed 100% negative results. The negative fertility reflects t...

Effect of Azadirachta indica leaf extracts on duration of oestrous cycle of adult rats was studied. The extract (200 mg/kg) induced cornified phase of the cycle which persisted till the last day of treatment. Possible reasons behind the results are discussed.

Drought stress is one of the most determinative factors of agriculture and plays a major role in limiting crop productivity. This limitation is going to rising through climate changes. However, plants have their own defense systems to moderate the adverse effects of climatic conditions. MicroRNA-mediated post-transcriptional gene regulation is one of these defense mechanisms. The root endophyti...

Hypoglycaemic effect was observed with Azadirachta indica when given as a leaf extract and seed oil, in normal as well as diabetic rabbits. The effect, however, was more pronounced in diabetic animals in which administration for 4 weeks after alloxan induced diabetes, significantly reduced blood glucose levels. Hypoglycaemic effect was comparable to that of glibenclamide. Pretreatment with A. i...
