The results 1 from measurements made with the glass electrode and spectrophotometer show that brilliant cresyl blue penetrates as free base into the vacuoles of living cells of Nitella. The present paper describes similar experiments with azure B, methylene blue, and crystal violet. Since the methods for the condition of cells, extraction of the sap, penetration experiments, extraction of free ...

STATEMENT OF THE PROBLEM Oral candidiasis is the most common opportunistic infection affecting the human oral cavity. Photodynamic therapy, as one of its proposed treatment modalities, needs a distinct dye for achieving the best effect. PURPOSE The purpose of this study was to evaluate photosensitization effects of four distinct dyes on standard suspension of Candida albicans (C. albicans) an...

Sentinel lymph node biopsy has become the standard of clinical care in staging axillary lymph nodes for breast carcinoma. While deemed safe and effective, methylene blue dye has been associated with infection, fibrosis, and skin and fat necrosis. The variable appearance of surgical dye-related fibrosis and fat necrosis on imaging studies poses a challenge to both radiologists and clinicians. We...

The textile industry including batik has provided broad benefits to society from an economic standpoint. However, there is negative impact wastewater generated in the production process, which containing dyes. Various types of dyes are used coloring and methylene blue one most dye. ways have been done treat blue. Methylene processing techniques by adsorption carried out with various adsorbents....

In the present study, cotton fabric was exposed to laser exposure at different energy levels and then the silver nanoparticles were coated on untreated and laser treated cotton fabrics. Methylene blue dye was used to detect the presence of carboxylic acid groups (-COO) on laser treated cotton and the dye absorption results were determined spectrophotometrically. ICP-OES (Inductively Coupled Pla...

Microfabricated biochips are very efficient platforms for analysis of biologically important molecules such as DNA, RNA, enzymes, antibodies etc. These devices requires sample in micro/nano volume and produces faster and better results. For these reasons, we fabricated a simple, disposable microfluidic device for amperometric detection of DNA intercalated with methylene blue redox dye. The devi...

In 1891 Guttmann and Ehrlich (P. Guttmann and P. Ehrlich, Berlin Klin. Wochenschr. 28:953-956, 1891) were the first to report the antimalarial properties of a synthetic, rather than a natural, material when they described the clinical cure of two patients after oral administration of a thiazine dye, methylene blue. Since that time, sporadic reports of the antimalarial properties of several xant...

The rate of diffusion through the non-aqueous layer of the protoplasm depends largely on the partition coefficients mentioned above. Since these cannot be determined we have employed an artificial system in which chloroform is used in place of the non-aqueous layer of the protoplasm. The partition coefficients may be roughly determined by shaking up the aqueous solutions with chloroform and ana...

The search for new materials that can be applied in the treatment of injured human tissues has led to development dressings. Membranes have potential as dressing because they fitted and interact with tissue surface. In this study, we analyze morphological properties wettability latex membranes, along incorporation photosensitizer methylene blue, context utility membranes curative applications i...
