Impact of the combined effect of seawater exposure with wastewater and FeO nanoparticles on Chlorella vulgaris microalgae growth, lipid content, biochar, and bio-oil production.

Microalgae is one the promising source of energy for the production of biofuel and other value-added products to replace the existing conventional fossil fuels. However, low lipid content and poor cell harvesting are the key challenges. Based on the growth conditions the lipid productivity will be affected.

Mitochondrial cytochrome oxidase I (COI) DNA sequencing of the ascidians Didemnum granulatum (JQ013198) and D. psammathodes (JN624758).

Two colonial ascidians Didemnum granulatum and D. psammathodes were collected from Tuticorin coastal waters. These ascidians were sequenced at 603 and 576 bp region of the mitochondrial cytochrome oxidase subunit I gene (COI) for phylogenetic analysis.

Promotion of rat hepatocarcinogenesis by dimethylarsinic acid: association with elevated ornithine decarboxylase activity and formation of 8-hydroxydeoxyguanosine in the liver.

Arsenicals are epidemiologically significant chemicals in relation to induction of liver cancer in man. In the present study, we investigated the dose-dependent promotion potential of dimethylarsinic acid (DMAA), a major metabolite of inorganic arsenicals in mammals, in a rat liver carcinogenesis model. In experiment 1, glutathione-S-transferase placental form (GST-P)-positive foci, putative preneoplastic lesions, were employed as endpoints of a liver medium-term bioassay for carcinogens (Ito test).

Interior remodeling of the shell by a gastropod mollusc.

As the Conus shell grows by spiraling of the outer lip around the axis, profound internal shell dissolution thins the walls of the protected penultimate whorl from several millimeters to <50mum. Shell material is added to the inside of the spire and the anterior part of the columella. The resulting shell has a uniformly thick last whorl and thickened spire that enhance defense against crushing predators and a greatly expanded interior living space for the animal.
