The rate of penetration of brilliant cresyl blue into the living cells of Nitella indicates that the dye enters only in the form of the undissociated molecule. At equilibrium the total concentration of the dye in the sap is proportional to the concentration of the free base in the outside solution.

decolorization of remazol brilliant blue r (rbbr) by trametessp. pellets was studied in a batch reactor. dye removal process was performed in shaken flasks which contained 100 ml of rbbr aqueous solution and fungal pellets. the process was followed for 48 h and the dye removal was analyzed at a visible spectrum of 590 nm. response surface methodology (rsm) employing box behnken design at three ...

The central nervous system (CNS) is an active participant in the innate immune response to infection and injury. In these studies, we show embryonic cortical neurons express a functional, deoxyribonucleic acid (DNA)-responsive, absent in melanoma 2 (AIM2) inflammasome that activates caspase-1. Neurons undergo pyroptosis, a proinflammatory cell death mechanism characterized by the following: (a)...

By PHAEDON FESSAS F EW EXAMPLES of erythrocytic inclusions due to abnormalities of the hemoglobin molecule are known. The first concerns Hb H.”2 Although the precipitates of Hgb H, such as is observed in the usual test employing brilliant cresyl blue, are produced artificially, there is evidence that some are formed spontaneously in vivo.’4 The second example is that of Hb Zurich; the precipita...

A glass electrode apparatus is described with which pH measurements can be made with as small volumes as 2 drops (about 0.14 cc.) of solution. Using this apparatus the change of pH of the vacuolar sap of Nitella, due to the penetration of brilliant cresyl blue, has been readily followed. The sap and the dye have been found to poison the usual type of hydrogen electrode.

This month's installment of Generally Physiological concerns signals from apoptotic cells that promote muscle development, food dyes that selectively block the pannexin 1 (Panx1) ATP channel, and photoperiod-dependent switches in neurotransmit-ter phenotype. The multinucleated myofibers that make up muscle are generated through the fusion of mononuclear myoblasts. Noting that a signaling module...

Box 56, Biocenter 1, FI 00014 University of Helsinki, Finland Email: [email protected] Abstract: To find out ability of fourteen basidiomycetes and four ascomycetes strains to grow in the presence of synthetic colour dyes and to degrade them, fungi were ...

It has been shown by several investigators I that when the pl-I value of the external dye solutions is increased, the rate of accumulation of a basic dye in the cell sap is accelerated. Two different explanations for this have been given. Some have accounted for it on the basis that the basic dye enters the cell in the form of a dye hydrate and combines with the substances in the cell; and that...

Septins are GTP-binding proteins that form cytoskeleton-like filaments, which are essential for many functions in eukaryotic organisms. Small molecule compounds that disrupt septin filament assembly are valuable tools for dissecting septin functions with high temporal control. To date, forchlorfenuron (FCF) is the only compound known to affect septin assembly and functions. FCF dampens the dyna...
