Thirteen-week subchronic toxicity studies of direct blue 6, direct black 38, and direct brown 95 dyes were conducted by administering the test chemicals in feed to Fischer 344 rats and B6C3F1 mice. Groups of 10 rats and 10 mice of each sex were administered one of the three dyes at one of five concentrations for 13 weeks and then necropsied, beginning the second day after the end of the dosing ...

There were investigated the seasonal and spatial dynamics of content nutrients in lakes Opechen’ system. It has been established that reservoirs urbanized territory, addition to external load, depends significantly on their migration from bottom sediments under oxygen deficiency reduction conditions. The concentration dissolved value redox potential within 0–16.2 mg/dm3 -129÷295 mV. Dissolved (...

microRNAs (miRNA) are involved in cancer development and progression, acting as tumor suppressors or oncogenes. Here, we profiled the expression of 290 unique human miRNAs in 11 normal and 106 bladder tumor samples using spotted locked nucleic acid-based oligonucleotide microarrays. We identified several differentially expressed miRNAs between normal urothelium and cancer and between the differ...

The photodegradation of Direct Blue 258, a member of the group of azo dyes which are commonly used in the various branches of the industry, was studied. The photostability of this dye was not previously surveyed. Photocatalytic degradation method was evaluated. The both light source include solar simulated (UV 400 W lamp) and sun light (E= 400 W/m2) and titanium dioxide nanoparticles were used ...

The interactive effects of predator density and prey distribution on the foraging behavior of an important estuarine predator were studied, at a fine temporal scale, using ultrasonic telemetry. The movement and agonistic activity of individual blue crabs Callinectes sapidus were monitored in large field enclosures, in which the density of crabs and the distribution of patches of bivalve prey Ma...

Removal of synthetic dyes is one of the main challenges before releasing the wastes discharged by textile industries. Biodegradation of azo dyes by alkaliphilic bacterial consortium is one of the environmental-friendly methods used for the removal of dyes from textile effluents. Hence, this study presents isolation of a bacterial consortium from soil samples of saline environment and its use fo...
