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....

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...

In this study, we exploit dye patterns to identify flow types in macroporous soils as a step forward from using dye patterns simply as qualitative pictures that illustrate preferential flow. Dye tracer experiments at different irrigation rates and initial soil moisture conditions were carried out on three hillslope sites. Several vertical and horizontal soil sections were prepared after each ex...

Exposure to artificial food colors and additives (AFCAs) has been implicated in the induction and severity of some childhood behavioral and learning disabilities. N-methyl-D-aspartate receptors (NMDARs) and nicotinic acetylcholine receptors (nACHRs) are thought to be effective in the learning and memory-generating process. In this study, we investigated the effects of intrauterine exposure to A...

Gravely calcareous soils cover approximately most of arid lands (in percent); however, the solute transport behavior in these soils remains a current issue. This research aimed at estimating and correlating the solute transport parameters in gravely calcareous soils as being affected by different land uses through the knowledge of the soil morphological, physical, and chemical properties. Four ...

Medicinal carbon (MC) tablets were prepared to obtain an oral dosage form that can be easily taken. The MC tablets were made by the wet granule compression method, in which hydroxypropyl cellulose (HPC), carboxymethyl cellulose sodium (CMC-Na) and maltitol (MT) were applied as binders. Brilliant Blue FCF (BB) was used as a model drug. The binders were evaluated in terms of formability of the gr...

BACKGROUND Prion diseases are fatal neurodegenerative disorders with no effective therapy currently available. Accumulating evidence has implicated over-activation of P2X7 ionotropic purinergic receptor (P2X7R) in the progression of neuronal loss in several neurodegenerative diseases. This has led to the speculation that simultaneous blockade of this receptor and prion replication can be an eff...
