Fruit waste-derived cellulose-polyaniline composite for adsorption-coupled reduction of chromium oxyanions.

Hexavalent chromium oxyanions, known as potentially toxic micropollutants, exist in the effluents and discharges of metallurgical, electroplating, refractory, chemical, and tanning industries. The exposure of chromium-contaminated water causes severe health hazards. The present work outlines a facile approach to grow polyaniline (PANI) on fruit-waste-derived cellulose (CEL) via oxidative polymerization of aniline; followed by chemical processing with NHOH to obtain CEL-PANI-EB composites for adsorptive separation-coupled reduction of highly toxic hexavalent chromium oxyanions.

Adsorptive removal of multiple organic dyes from wastewater using regenerative microporous carbon: Decisive role of surface-active sites, charge and size of dye molecules.

Present work addresses the synthesis of microporous activated carbon (SDAC) by a facile thermochemical conversion of teak sawdust powder. The high surface area (1999 m g), excellent microporosity (average pore size: 2.62 nm), and turbostratic carbon structure with intertwined graphitic domains make SDAC a highly efficient adsorptive material for the removal of organic pollutants.

Anti-heat shock protein-27 (Hsp-27) antibody levels in patients with chest pain: association with established cardiovascular risk factors.

Background: Antibody titres to several heat shock proteins (Hsps) have been shown to be associated with risk factors for cardiovascular disease (CVD), but there are no data for Hsp-27. We developed an ELISA for total IgG antibody concentrations, applying this to individuals with and without acute coronary syndrome, and have assessed the relationship between antibody levels and individual coronary risk factors.

Methods: Blood was collected from 63 healthy controls without a history of chest pain or CVD and 60 patients admitted to hospital with acute cardiac chest pain on admission and approximately 12 h after the acute event.
