Fine roots (≥1 mm) production in Chir Pine (Pinus roxburghii Sarg.) forests was estimated across three different seasons for one year at four sites located between 1600–1850 meters elevation on two contrasting aspects. At each site three different slope positions (ridge slope, mid hill slope and hill base) were selected for the study. The tree density(More)
Pseudomonas aeruginosa is an opportunistic bacterium known for causing chronic infections in cystic fibrosis and chronic obstructive pulmonary disease (COPD) patients. Recently, several drug targets in Pseudomonas aeruginosa PAO1 have been reported using network biology approaches on the basis of essentiality and topology and further ranked on network(More)
We studied variations in tree biomass and carbon sequestration rates of Chir Pine (Pinus roxburghii. Sarg.) forest in three categories of forest disturbance, protected, moderately disturbed, and highly disturbed. In the first year, total biomass was 14.7 t·ha−1 in highly disturbed site, 94.46 t·ha−1 in moderately disturbed forest, and 112.0 t·ha−1 in(More)
The effect of soil solarization on physical, chemical and biological properties of soil was studied, along with the response of cauliflower seedlings following solarization. Nursery beds were covered with transparent polyethylene sheet and soil temperature and moisture were recorded. Soil samples were collected five times for analysis. Three cauliflower(More)
Two conformational polymorphs of novel 2-[2-(3-cyano-4,6-dimethyl-2-oxo-2H-pyridin-1-yl)-ethoxy]-4,6-dimethyl nicotinonitrile have been developed. The crystal structure of both polymorphs (1a and 1b) seems to be stabilized by weak interactions. A difference was observed in the packing of both polymorphs. Polymorph 1b has a better binding affinity with the(More)
UNLABELLED Bioterrorism is the intended use of pathogenic strains of microbes to widen terror in a population. There is a definite need to promote research for development of vaccines, therapeutics and diagnostic methods as a part of preparedness to any bioterror attack in the future. BIRS is an open-access database of collective information on the(More)
BACKGROUND Local steroid injection is one of the treatment modalities for carpal tunnel syndrome (CTS). Symptomatic and electrophysiological improvement has been previously documented. The electrophysiological parameter, which represents the most consistent change after local steroid injection, is not well-known. OBJECTIVE The objective of this study was(More)
Bacosides, constituents of Bacopa monnieri (Linn.), are reported to be potential therapeutic saponins in the cure of Parkinson’s disease (PD). However, detailed mechanism for control of PD by bacosides is not well documented. PD has been reported to be caused by genetic mutations in leucine-rich repeat kinase 2 (LRRK2) leading to higher kinase activity that(More)
Series of 1,5-diaryl pyrazole ester derivatives have been synthesized and found to contain potent inhibitory activity against cyclooxygenase-2 (COX-2) enzyme. The article describes synthesis of the target pyrazole analogs and biological assay using Carrageenan induced rat paw for investigation.
