Assessment of emerging and persistent contaminants in an anthropogenic-impacted watershed: Application using targeted, non-targeted, and in vitro bioassay techniques.

Emerging and persistent contaminants (EPC) pose a significant challenge to water quality monitoring efforts. Effect-based monitoring (EBM) techniques provide an efficient and systematic approach in water quality monitoring, but they tend to be resource intensive. In this study, we investigated the EPC distribution for various land uses using target analysis (TA) and non-target screening (NTS) and in vitro bioassays, both individually and integrated, in the upper Ping River Catchment, northern Thailand.

Application of multipoint dose rate measurement for radioactive inventory estimation in waste drums.

Dose-to-Curie (DTC) conversion is a fast and simple method for quantification of radionuclide content in solid waste packages with a prior knowledge of waste matrix and radionuclide composition of the waste stream. A dose to curie conversion factor generated based on an assumed radioactivity distribution in the package is used for conversion of the measured dose rate to activity. The difference between the radionuclide distribution for drum from field and the assumed distribution is a major source of error in activity estimation using this technique.

Removal of vanadium from wastewater using surface-modified lignocellulosic material.

Palm fruit husk, a lignocellulosic material, is an agricultural solid waste. Since raw palm fruit husk does not adsorb V (V), it was subjected to surface modification with a cationic surfactant cetyl trimethyl ammonium bromide (CTAB). The surface-modified palm fruit husk showed adsorption capability for V (V).

Effect of troxerutin on 2-aminoanthracene and DNA interaction and its anti-mutagenic property.

One of the pivotal mechanisms projected for bioflavonoids in cancer chemoprevention is through their intervention against mutagen-DNA interaction. Recent literatures emphasize the role of troxerutin (TXER) as an emerging anticancer agent. However, there are no reports on its intervention in any carcinogen-DNA interaction.

Production of Non-Ribosomal Peptide Synthetase (NRPS)-Dependent Siderophore by Aeromonas Isolates.

Background: Aeromonas species are Gram-negative ubiquitous bacteria, facultative anaerobic rods that infect both invertebrates and vertebrates. Various fish species develop hemorrhagic disease and furunculosis due to Aeromonas spp. Aeromonas strains generate certain active compounds such as siderophores, which are the final products of non-ribosomal peptide synthetase (NRPS) activity.

Characterizing breast cancer tissues through the spectral correlation properties of polarized fluorescence.

We study the spectral correlation properties of the polarized fluorescence spectra of normal and cancerous human breast tissues, corresponding to patients belonging to diverse age groups and socioeconomic backgrounds. The emission range in the visible wavelength regime of 500 to 700 nm is analyzed, with the excitation wavelength at 488 nm, where flavin is one of the active fluorophores. The correlation matrices for parallel and perpendicularly polarized fluorescence spectra reveal correlated domains, differing significantly in normal and cancerous tissues.
