Molecular characterization of an endophytic strain of Bacillus subtilis with plant growth-promoting properties from a wild relative of papaya.

Aim: Bacillus subtilis is usually found in soil, and their biocontrol and plant growth-promoting capabilities are being explored more recently than ever. However, knowledge about metabolite production and genome composition of endophytic B. subtilis from seeds is limited.

Study on groundwater pollution and its human impact analysis using geospatial techniques in semi-urban of south India.

Groundwater recharging and thus renewable groundwater supplies will experience considerable changes due to climate change. The present investigation focussed to evaluate the susceptibility of subsurface water in rapid developing textile industrial region of Southern India. To determine the aquifer's susceptibility, the DRASTIC-LU Remote sensing and GIS based vulnerability model was applied and the results were compared with human activity risk (HAR) analysis to ensure the water borne disease on human health.

Depression and its role in adherence to anti-retroviral treatment in people living with HIV and AIDS in Chennai.

Context: The AIDS epidemic has drastically reduced in India since it was first identified in 1986, largely due to the widespread availability of anti-retroviral treatment (ART). Management of HIV is currently more focussed on long term morbidities, including mental health. Depression is the most common co-morbidity seen in people living with HIV.

Surface modified and functionalized graphene oxide membranes for separation of strontium from aqueous solutions.

Graphene oxide-strontium (GO-Sr) composites prepared under different ambient conditions were characterized using morphological and spectroscopic techniques to optimize the uptake of Sr from aqueous solutions. These studies indicated that interactions among GO and Sr ions are highly sensitive to size and aging of GO sheets, as well as pH of the ambience. Further, the extent of Sr uptake on GO sheets was found to be largely influenced by relative fractions of the associated -COOH, -OH, C-O-C functional groups and sp-C domains.

Techniques for characterization and eradication of potato cyst nematode: a review.

Correct identification of species and pathotypes is must for eradication of potato cyst nematodes (PCN). The identification of PCN species after completing the life cycle is very difficult because it is based on morphological and morphometrical characteristics. Genetically different populations of PCN are morphologically same and differentiated based on the host differential study.

One-pot synthesis of three-dimensional MnO microcubes for high-level sensitive detection of head and neck cancer drug nimorazole.

We described a three-dimensional MnO microcubes (3D-MnOMCs) synthesised via a facile hydrothermal route for the determination of nimorazole (NMZ), an important drug that used in the treatment of head and neck cancer. The 3D-MnO MCs possess large active area and high conductivity, and 3D-MnO MCs film modified screen-printed carbon electrode (3D-MnOMCs/SPCE) was fabricated which displayed excellent electrocatalytic ability towards NMZ. Under optimised working conditions, the modified electrode responded linearly to NMZ in the 0.

Molybdenum disulfide nanosheets coated multiwalled carbon nanotubes composite for highly sensitive determination of chloramphenicol in food samples milk, honey and powdered milk.

We have described a hybrid material that consists of molybdenum disulfide nanosheets (MoS) coated on functionalized multiwalled carbon nanotubes (f-MWCNTs) for sensitive and selective determination of chloramphenicol (CAP). The MoS/f-MWCNTs nanocomposite was successfully prepared through a hydrothermal process and its structure was characterized by scanning electron microscopy, transmission electron microscopy, energy-dispersive X-ray spectroscopy, electrochemical impedance spectroscopy and cyclic voltammetry. The MoS/f-MWCNTs nanocomposite holds excellent electrochemical properties and it displays excellent electrocatalytic ability to CAP.

Floating-bioadhesive microspheres containing acetohydroxamic acid for clearance of Helicobacter pylori.

A new strategy based on gastric retention is proposed for the treatment of Helicobacter pylori. (H. pylori).
