Loss of nitrogen from the soil-plant system has raised environmental concern. This study assessed the fluxes of nitrous oxide (N2O) in the subsurface flow constructed wetlands (CWs). To better understand the mechanism of N2O emission, spatial distribution of ammonia-oxidizing bacteria (AOB) in four kinds of wetlands soil were compared. N2O emission data showed large temporal and spatial variati...

The detection of incipient host-shifts is important to the study of emergent diseases because it allows the examination of ecological and genetic conditions that favor novel inter-species transmission. Mixed populations of Silene latifolia and Silene vulgaris were investigated for the putative occurrence of host-shifts by the fungal plant pathogen Microbotryum violaceum (the cause of anther-smu...

Considering the indigenous utilization of Quercus incana Roxb., the present study deals with the investigation of antioxidant, free radical scavenging activity, total phenolic content, and antimicrobial activity of Q. incana Roxb. In vitro antioxidant activity of the plant fractions were determined by 1,1-diphenyl-2-picrylhydrazyl and nitric oxide scavenging method. Total phenolic contents were...

Dalbergia sissoo and Azadirachta indica are commonly known trees of India. They belong to family leguminoseae (fabaceae) and meliaceae respectively. They are broadly used in folk medicine for several diseases. The present study is carried out on biochemical parameters i.e. on content of protein and glycogen with standardized method in liver and kidney of Sprague-dawley rats. Due to combined ext...

BACKGROUND Bacterial Infections involving multi-drug resistant (MDR) phenotypes constitute a worldwide health concern. The present work was designed to assess the antibacterial properties of the methanol extracts of six medicinal plants (Anthocleista schweinfurthii, Nauclea latifolia, Boehmeria platyphylla, Caucalis melanantha, Erigeron floribundus and Zehneria scobra) and the effects of their ...
