Voltage-sensitive dyes (VSDs) and optical imaging are useful for studying spatiotemporal patterns of population neuronal activity in cortical tissue. Using a photodiode array and absorption dyes we were able to detect neuronal activity in single trials before it could be detected by local field potential (LFP) recordings. Simultaneous electrical and optical recordings from the same tissue also ...

Abstract The runoff of textile dye effluents into public water bodies is a major environmental and health problem. Color removal, in particular, has recently become substantial scientific interest, as revealed by the multitude related research reports. present study focused on measuring efficiency two marine algae, Ulva fasciata Pterocladia capillacea, bio-removal four synthetic dyes (RY2, RR19...

In skin and hair research drug targeting to the hair follicle is of great interest. Therefore the influence of permeant lipophilicity and vehicle composition on local accumulation has been examined using confocal laser scanning microscopy (CLSM). Formulations saturated with either Oregon Green 488, Bodipy FL C(5) or Bodipy 564/570 C(5) were prepared. The dyes were applied in citric acid buffer,...

The aim was to assess the ability of microcosms (laboratory-scale shallow ponds) as a post polishing stage for the remediation of artificial textile wastewater comprising two commercial dyes (basic red 46 (BR46) and reactive blue 198 (RB198)) as a mixture. The objectives were to evaluate the impact of Lemna minor L. (common duckweed) on the water quality outflows; the elimination of dye mixture...

    Background & Aims of the Study: Textile wastewaters are very various in chemical qualities. In other words, these industries are one of the largest producing dyes compounds; therefore their treatment is so complex and difficult. The aim of this study was to evaluate the potential removal of Reactive Red 198 and Blue Reactive 19 from synthetic solution by Acaciatortilis shu...

A total of twenty endophytic fungi successfully isolated from Melastoma malabathricum (Senduduk) were examined for their ability to decolourise azo dyes: Congo red, Orange G, and Methyl red and an anthraquinone dye, Remazol Brilliant Blue R. Initial screening on the glucose minimal media agar plates amended with 200 mg L(-1) of each respective dye showed that only isolate MS8 was able to decolo...

1. The interaction of electron-transporting particles from heavy mitochondria of ox heart with several fluorescent probes was examined. 2. 1-Anilinonaphthalene-8-sulphonate and 2-(N-methylanilino)naphthalene-6-sulphonate both show an energy-dependent response. 3. Energy transfer between the electron-transporting particles and the dyes and the kinetics of the dye-particle interaction were studie...

The binding behavior of guests (dyes and DNA) into peptide nanocapsules formed via self-assembly of a 24-mer b-annulus peptide fragment obtained from the capsid protein of the tomato bushy stunt virus is reported. The pH dependence of the f potential of the peptide nanocapsules indicates that the Cand N-termini are directed to the exterior and interior of the nanocapsules, respectively. Equilib...

BACKGROUND Total three Pleurotus species (P. ostreatus, P. sapidus, P. florida) was compared for ligninolytic enzyme production grown with Coralene Golden Yellow, Coralene Navy Blue and Coralene Dark Red azo dyes in liquid medium under shaking condition. RESULTS The biodegradation competency varied from species to species and it was found that P. ostreatus, P. sapidus and P. florida to 20 ppm...
