A 54-year-old healthy male presented complaining of sudden loss of vision in the right eye. Initial visual acuity was counting fingers. The patient's acute vision loss developed after sexual activity. Color fundus photos and fluorescein angiography were performed showing a large subinternal limiting membrane hemorrhage in the macular area. A 23-gauge sutureless pars plana vitrectomy with brilli...

The white rot fungi Stereum ostrea displayed a wide diversity in their response to supplemented inducers, surfactants, and copper sulphate in solid state fermentation. Among the inducers tested, 0.02% veratryl alcohol increased the ligninolytic enzyme production to a significant extent. The addition of copper sulphate at 300 μM concentration has a positive effect on laccase production increasin...

Adequate visualization and identification of the posterior hyaloid, epiretinal membranes and the internal limiting membrane are of paramount importance in modern vitreoretinal surgery. "Chromovitrectomy" is a term used for describing the vital dyes use in order to stain these transparent tissues and facilitate their manipulation during vitreous surgery. This article reviews the indications, app...

Over the past few decades, enzyme-based green and sustainable chemistry has attracted extensive research attention, which provides a promising alternative to conventional treatment methods of recalcitrant micropollutants. However, enzyme denaturation stability loss remain critical challenges for its potential applications in industrial wastewater treatment. In this study, laccase from Trametes ...

Sentetik boyaların varlığından kaynaklanan su kirliliği, dünyanın en önemli çevresel sorunlarından biridir. Remazol Brilliant Blue R (RBBR), tekstil endüstrisi atıksularından salınan ve suda ciddi kirliliğe neden olan oldukça toksik boyalardan Bu çalışmada, Pseudomonas putida ile üretilmiş biyojenik mangan oksit (BMO) RBBR’ nin giderimi incelenmiştir. BMO giderimi, çeşitli çözelti pH’ ı, dozajı...

This simple method of centrifugal analysis for total protein in human breast milk is based on the change in the wavelength of the absorbance maximum of Coomassie Brilliant Blue G-250 when the dye is bound to protein. Within-run and between-day CVs were 3.8% and 4.8%, respectively. Compared with a micro-Kjeldahl method for determination of total nitrogen, the coefficient of correlation was 0.99.

The capacities of 16 proteins, after being subjected to electrophoresis on polyacrylamide gel containing sodium dodecyl sulphate, to bind Coomassie Brilliant Blue G 250 have been measured. It is observed that absorption is a linear function of the surface area of the protein in spherical (globular) configuration. The dye binding capacity of proteins has been used to determine the molar ratio in...

A comparison has been made between reticulocyte preparations stained with purified azure B and with several commerically available batches of brilliant cresyl blue and new methylene blue. Marked variations were observed in the composition and staining performances of the various batches of the two commerically available dyes. Although there were no significant differences in reticulocyte counts...
