TL;DR: Three factors have been identified using Principal Component Analysis at the sampling sites comprising res Suspension of road dust due to vehicular activities, solid waste incineration, and industrial emission at urban site whereas resuspension of soil dust dueto vehicular emission, construction activities and wind blown dust carrying industrial emission, were common sources at rural site.

TL;DR: A new database of more than 1.6 million samples from 78 countries representing over 28,000 species, collated from existing spatial comparisons of local-scale biodiversity exposed to different intensities and types of anthropogenic pressures, from terrestrial sites around the world is described and assessed.
Abstract: Biodiversity continues to decline in the face of increasing anthropogenic pressures such as habitat destruction, exploitation, pollution and introduction of alien species Existing global databases of species’ threat status or population time series are dominated by charismatic species The collation of datasets with broad taxonomic and biogeographic extents, and that support computation of a range of biodiversity indicators, is necessary to enable better understanding of historical declines and to project – and avert – future declines We describe and assess a new database of more than 16 million samples from 78 countries representing over 28,000 species, collated from existing spatial comparisons of local-scale biodiversity exposed to different intensities and types of anthropogenic pressures, from terrestrial sites around the world The database contains measurements taken in 208 (of 814) ecoregions, 13 (of 14) biomes, 25 (of 35) biodiversity hotspots and 16 (of 17) megadiverse countries The database contains more than 1% of the total number of all species described, and more than 1% of the described species within many taxonomic groups – including flowering plants, gymnosperms, birds, mammals, reptiles, amphibians, beetles, lepidopterans and hymenopterans The dataset, which is still being added to, is therefore already considerably larger and more representative than those used by previous quantitative models of biodiversity trends and responses The database is being assembled as part of the PREDICTS project (Projecting Responses of Ecological Diversity In Changing Terrestrial Systems – wwwpredictsorguk) We make site-level summary data available alongside this article The full database will be publicly available in 2015

TL;DR: In vitro anti-tubercular activity of five medicinal plants showed that all these plants exhibited activity against MDR isolates of M. tuberculosis, and in BacT/ALERT also, extracts of these plants showed significant inhibition against M.culosis.
Abstract: Background & objectives Emergence of multi-drug resistant (MDR) and extensively-drug resistant (XDR) strains of Mycobacterium tuberculosis has further complicated the problem of tuberculosis (TB) control. Medicinal plants offer a hope for developing alternate medicines for the treatment of TB. The present study was done to evaluate in vitro anti-tubercular activity of five medicinal plants viz., Acalypha indica, Adhatoda vasica, Allium cepa, Allium sativum and Aloe vera. Methods Aqueous extracts of leaves of A. indica, A. vasica, bulbs of A. cepa, cloves of A. sativum and pure gel of A. vera leaves, were tested in vitro for their activity against two MDR isolates (DKU-156 and JAL-1236), reference susceptible strain M. tuberculosis H37Rv as well as rapid grower mycobacterial pathogen M. fortuitum (TMC-1529) using Lowenstein Jensen (L-J) medium and colorimetric BacT/ ALERT 3D system. Activity in L-J medium was evaluated by percentage inhibition which was calculated by mean reduction in number of colonies on extract containing as compared to extract free controls. Results Extracts of all the five plants A. indica, A. vasica, A. cepa, A. sativum and A. vera exhibited anti-tuberculosis activity in L-J medium, the proportion of inhibition of these plants extract in respect mentioned above is 95, 32, 37, 72, 32 per cent, respectively for MDR isolate DKU-156 and 68, 86, 79, 72, 85 per cent, respectively for another MDR isolate JAL-1236, while for sensitive M. tuberculosis H37Rv, inhibition was found to be 68, 70, 35, 63 and 41 per cent, at 4 per cent v/v concentration in L-J medium. There was no inhibition against rapid grower M. fortuitum (TMC-1529). In BacT/ALERT also, extracts of these plants showed significant inhibition against M. tuberculosis. Interpretation & conclusion Our findings showed that all these plants exhibited activity against MDR isolates of M. tuberculosis. While the anti-TB activity of A. vera, A. vasica and A. sativum against MDR isolates confirm earlier results, activity of the extracts of A. indica and A. cepa is reported for the first time. Further studies aimed at isolation and identification of active substances from the extracts which exhibited promising activities, need to be carried out.
