Explant cultures were established from capsule/epithelium preparations from both normal and cataractous lenses to investigate properties of human lens epithelial cells. The cultured cells were found to have similar membrane potentials to whole human lenses and isolated epithelia, and similar free ionic concentrations of potassium, sodium, and calcium (131 mM, 17 mM and 0.8 microM respectively) ...

We characterized gap junctional communication in the extraembryonic tissues of the 7.5-d gastrulating mouse embryo. At this stage of development, the extraembryonic tissues form a large part of the conceptus, and link the embryo proper to the maternal tissue. Using Lucifer yellow injections, cells in most extraembryonic tissues were observed to be very well dye coupled, the only exception being...

We report an environmentally friendly synthetic strategy to fabricate reduced graphene oxide (rGO)-based ternary nanocomposites, in which glutathione (GSH) acts both as a reducing agent for graphene oxide and sulfur donor for CdS synthesis under modified hydrothermal (MHT) conditions. The report becomes interesting as pH variation evolves two distinctly different semiconducting nanocrystals of ...

In the present study, the biobleaching potential of white rot fungus Cordyceps militaris MTCC3936 was investigated. For preliminary screening, decolorization properties of C. militaris were comparatively studied using whole cells in agar-based and liquid culture systems. Preliminary investigation in liquid culture systems revealed 100% decolorization achieved within 3 days of incubation for rea...

Azo dyes are widely used in textile, printing, cosmetic, drug and food-processing industries. They are also used extensively in laboratories as either biological stains or pH indicators. The extent of such use is related to the degree of industrialization. Since intestinal cancer is more common in highly industrialized countries, a possible connection may exist between the increase in the numbe...

Seventeen commonly used dyes and 16 of their metabolites or derivatives were tested in the Salmonella-mammalian microsome mutagenicity test. Mutagens active with and without added Aroclor-induced rat liver microsome preparations (S9) were 3-aminopyrene, lithol red, methylene blue (USP), methyl yellow, neutral red, and phenol red. Those mutagenic only with S9 activation were 4-aminopyrazolone, 2...

A new two-dimensional zinc(II) coordination polymer of 5-aminoisophtalic acid (H 2 AIP), namely [Zn(AIP)(DMSO)] n ( Zn-CP ), has been successfully prepared via conventional heating at 100 ?°C in a (2:1) dimethyl sulfoxide/ethanol solvent mixture. The compound characterized by FT-IR spectroscopy, elemental and thermogravimetric analyses, powder single-crystal X-ray diffraction techniques. Crysta...
