The in vivo response of adult northern quahogs, Mercenaria mercenaria, to Aureococcus anophagefferens (brown tide) at the level of the gill was determined using video-endoscopy. Feeding activity, particle-approach velocities, and ventral-groove-transport velocities were documented after the quahogs were exposed to Isochryis galbana (baseline observations) supplemented with either toxic or nonto...

This review addresses recent and not so recent works that emphasize on the mechanisms by which liver damage can induce encephalopathy. Hepatic encephalopathy constitutes an intriguing complication in severe liver acute and chronic disease, whose pathophysiology is still not completely understood. In this pathology, alterations in normal brain function are associated with morphological and funct...

Cyanobacterial bloom, also called blue-green algae, all over the world is generating great concern due to effect of temperature resulting from global warming. Microcystis aeruginosa well known be major causative agent algal bloom. However, there a need for more critical detection relationship between and growth rate Microcystic aeruginosa. In present study, we cultivated batch culture (Toxic No...

The intracellular localization and colocalization of a fluorescently labeled G3 amine-terminated cationic polyamidoamine (PAMAM) dendrimer and its biotin-pyridoxal (BC-PAMAM) bioconjugate were investigated in a concentration-dependent manner in normal human fibroblast (BJ) and squamous epithelial carcinoma (SCC-15) cell lines. After 24 hours treatment, both cell lines revealed different pattern...

Five metallic cations (Fe3+, Cr3+, Cal+, Mg2+, Mn2+; concentration range, 1.85 X 10-4 to 37 X 10-4 M) were incorporated individually as chlorides into nutrient broth and agar media used for the recovery of phenol-treated Escherichia coli. The effects observed varied with the concentration and the ionic species. In nutrient agar, Fe3+ and Cr3+ were generally beneficial but were toxic at 37 X 10-...

Keeping in view the effects of industrial effluents mainly the bio-accumulative heavy metals on plants, we propose the present study. Experiments showed increasing concentrations of lead acetate treatments suppress germination of Bengal gram seeds. Root development in control seeds were appropriate compared to the seeds in 1mM concentration whereas seeds in 2mM and 4mM were more affected by lea...

Intraoperative early detection of anemia, identifying toxic levels of carboxyhemoglobin after carbon monoxide exposure and titrating drug dosage to prevent toxic levels of methemoglobin are important goals. The pulse oximeter works by illuminating light into the tissue and sensing the amount of light absorbed. The same methodology is used by laboratory hemoglobinometers to measure hemoglobin co...

The variation of microbial activity during acclimation to 4-chlorophenol (4CP) in an aerobic automated sequencing batch reactor was studied. The results show a reduction in degradation time as the acclimation process occurred. During acclimation for an initial concentration of 50 mg 4CP/L, degradation time was reduced from 40 h to 50 min after 10 cycles. In the case of an initial concentration ...
