Studies on Dyes
"Previous studies showed that repeated ingestion of erythrosine B [Red 3] (artificial food color) developed behavioral hyperactivity, but nothing is known about its single administration effect as well as the neurochemical (s) involvement. ... The degree of erythrosine-induced inhibition of both MA [motor activity] and brain regional serotonergic activity was dosage dependent. ... Altogether th...
متن کاملSpectrophotometric Studies of Penetration of Dyes
Spectrophotometric measurements show that the non-medullated nerve of a lobster claw is capable of absorbing methylene blue, azure B, or acid fuchsin dissolved in sea water but this does not necessarily imply that the dyes penetrate into the interior of the nerve.
متن کاملPicosecond Fluorescence Studies of Xanthene Dyes
Subnanosecond lifetime measurements using picosecond pulses from a mode locked Nd3+/glass laser together with conventional absorption and fluorescence yield methods have been used to study the photophysics of fluorescein and three of its halogenated derivatives (eosin, erythrosin, and rose bengal) in aqueous and simple alcoholic solvents. For each of the dye molecules absorption and fluorescenc...
متن کاملStudies on Adsorption of Some Organic Dyes from Aqueous Solution onto Graphene Nanosheets
Graphene, a new member of the carbon family, was used as an adsorbent due to its exceptional capability to remove Rhodamine B (RB) and Malachite Green (MG), two organic dyes, from aqueous solutions. Adsorption kinetics of RB and MG onto graphene and adsorption capacity of the adsorbent were studied. Also the effects of parameters, including pH, contact time, temperature, and adsorbent dosag...
متن کاملHygienic Quality of Foods Served on Aircraft
This study set out to evaluate the microbiological hazards associated with the foods served on aircraft. To identify the microbiological quality of hot and cold meals prepared worldwide, samples of aircraft meals were monitored for Salmonella between 1989 and 1994, and for indicator bacteria and Staphylococcus aureus, Bacillus cereus and Clostridium perfringens between 1991 and 1994. Additional...
