It has been shown by several investigators I that when the pl-I value of the external dye solutions is increased, the rate of accumulation of a basic dye in the cell sap is accelerated. Two different explanations for this have been given. Some have accounted for it on the basis that the basic dye enters the cell in the form of a dye hydrate and combines with the substances in the cell; and that...

Interest in novel ligninolytic bacteria has remained topical due to, in part, the maneuverability of the bacterial genome. Conversely, the fungal genome lacks the dexterity for similar maneuverability thus, posing challenges in the fungal enzyme yield optimization process. Some impact of this situation includes the inability to commercialize the bio-catalytic process of lignin degradation by fu...

PURPOSE To evaluate the selectivity and strength of intraoperative trypan blue staining during removal of epiretinal membranes (ERMs) and the internal limiting membrane. METHODS Based on intraoperative videos, 51 consecutive chromovitrectomies in 51 patients with macular holes, macular pucker, vitreomacular traction syndromes, or persistent macular edema were retrospectively studied. Fifteen ...

I The continuous faecal marker chromic oxide, Cr,O,, and the intermittent marker brilliant blue were used together in metabolic balance studies of calcium and magnesium in two young women. 2. Faecal output was derived by four methods: no marker, brilliant blue, Cr,Os, or both brilliant blue and Cr,Os. 3. Balances of Ca and Mg derived by the four methods of obtaining faecal output were compared....

A novel implementation of broadband cavity enhanced absorption spectroscopy (BBCEAS) has been used to perform sensitive visible wavelength measurements on liquid-phase solutions in a 2 mm cuvette placed at normal incidence to the cavity mirrors. The overall experimental methodology was simple, low cost, and similar to conventional ultraviolet-visible absorption spectroscopy. The cavity was form...

The objective of the present study was to establish a methodology using tracer substances for the evaluation of the distribution and amount of spray deposits, with the possibility to adjust the surface tension of the spraying solution. The following products were tested: 0.15% Brilliant Blue, 0.15% Saturn Yellow in 0.015% Vixilperse lignosulfonate and 0.005% sodium fluorescein, and mixtures of ...

The sorption studies of coomassie brilliant blue (CBB) from aqueous solution have been carried out on wheat bran (WB). Coomassie brilliant blue on wheat bran was used to study the adsorption behavior under various parameters such as pH, dosage amount, and contact time. It was observed that under optimized conditions up to 95.70% dye could be removed from solution onto WB. Langmuir and Freundlic...
