Microplastics and organics - A comparative study of sorption of triclosan and malachite green onto polyethylene.

This study aims to elucidate interaction of organics with microplastics in a comparative manner via the use of two model compounds (i.e., triclosan (TCS) and malachite green (MG)) having different physicochemical properties, onto polyethylene (PE).

Hydrocarbon degradation by a new Pseudomonas sp., strain RW-II, with polycationic surfactant to modify the cell hydrophobicity.

Pseudomonas putida RW-II isolated from petroleum refinery wastewater was tested for hydrocarbon degradation potential in the presence of polycationic surfactant, cetyl trimethylammonium bromide (CTAB). The effects of CTAB on growth profile, cell surface hydrophobicity, cell adhesion, zeta potential and hydrocarbon biodegradation were investigated. The addition of CTAB had a significant effect on the growth profile of RW-II and the growth was increased 1.

Hypofunction of the dorsal hippocampal NMDA receptors impairs retrieval of memory to partially presented foreground context in a single-trial fear conditioning in rats.

In the present study, the effects of N-methyl-D-aspartate (NMDA) receptor antagonist, D,L-2-amino-5-phosphonopentanoic acid (AP5) bilaterally infused into the dorsal hippocampus (2.0 microl /5 microg), on the retrieval of fear memory to partial and whole foreground cues were evaluated by using a step-through passive avoidance and Pavlovian fear conditioning. In the both conditioning tasks, following a 30-s preshock exposure period to the shock-associated context, rats received a single shock in a foreground manner for fear memory exhibition by freezing.
