The composition, with respect to nucleic acids, of the L.E. bodies resulting from the action of the plasma of patients with systemic lupus erythematosus on substrate leukocyte nuclei in different kinds of preparations was compared microspectrophotometrically with that of control lymphocyte nuclei. Binding of the basic dye methyl green to DNA was uniformly found to be depressed in L.E. bodies as...

It has been repeatedly found (e.g., Beck, 1982; Beck & Ambler, 1973) that a tilted T is detected better than an L when presented on the background of a number of upright Ts, although in isolation both are discriminated from an upright T about equally well. We demonstrate that an analogous interaction between context presence and stimulus type can be obtained with color stimuli: A light green wa...

I . The specificity of a number of samples of methyl green for egg-shell material in Fasciola hepatica was investigated. 2. A method for distinguishing between specific and non-specific stains by paper chromatography is described. 3. Specific stains gave almost identical chromatograms with an Rf value of 083 for both green and violet constituents. Non-specific samples gave chromatograms with an...

In this paper, we have done the photodegradation of Methyl green dye in presence of prepared Ni0.10:La0.05:TiO2 nanocomposites. The nanocomposites of Ni0.10:La0.05:TiO2 was prepared by the solution impregnation method. The characterization of Synthesized TiO2 and Ni0.10:La0.05:TiO2 nanocomposites were done by X-Ray Diffractometer, SEM, TEM, UVVis, FT-IR, Band gap energy and BET. The photocataly...

There are typographical errors in the published article. There are three instances in the article that refer to “26S rRNAs”. This is incorrect. The correct text is “28S rRNAs”. In the Abstract, “26oC” is incorrect. The celcius degree sign should be superscripted to read: “26°C”. In the Fig. 1 legend, the following text has a typographical error: "Positive cells are brown (DAB) and the backgroun...

The cation of methyl green carries two positive charges, that of malachite green only one; but the two dyes behave towards tissue-constituents in almost exactly the same way. These dyes are not specific for chromatin. They colour certain objects that are devoid of DNA, even when they are used in very dilute solution. The granules of cells called Kornchenzellen in the connective tissue of the co...

Water is a versatile solvent in many ways, and in this sense performing organic reactions in this medium is now of great interest. The one-pot reaction of ethyl acetoacetate or benzyl acetoacetate, with benzaldehydes and malononitrile to provide some novel 6-amino-4-aryl-5-cyano-2-methyl-4H-pyran-3-carboxylates has been performed over nano MgO with high performance in water as a green solvent a...

Nanomagnetite-Fe3O4 is used as a highly efficient, mild, green and recyclable nanomagnetite catalyst for the synthesis of 4,4´-(arylmethylene)-bis(3-methyl-1-phenyl-1H-pyrazol-5-ol) derivatives in solvent-free conditions. The condensation reaction of 3-methyl-1-phenyl-1H-pyrazol-5(4H)-one with aromatic aldehydes affords the title compounds in high yields and short reaction times. The nanocataly...
