86 NATURE | VOL 402 | 4 NOVEMBER 1999 | www.nature.com Calculation of correlated mRNA expression Results of 97 individual publicly available DNA chip yeast mRNA expression data sets were encoded as a string of 97 numbers associated with each yeast open reading frame (ORF) describing how the mRNA of that ORF changed levels during normal growth, glucose starvation, sporulation and expression of m...

In order to determine the prevalence and percentage distribution of ringed sideroblasts in primary myelodysplastic syndromes, the results of Prussian blue staining were analysed in 133 cases. Ringed sideroblasts ranging from 1 to 86% of cells were found in 76 (57%) cases. The cases of primary myelodysplastic syndrome corresponding to the group entitled "acquired idiopathic sideroblastic anaemia...

Photoreactivity of cadmium sulfide nanoparticles as undoped and doped with manganese, nickel and copper were studied in the decolorization of methylene blue and safranin under UV and Vis irradiations. The dopant, mole fraction of dopant to cadmium ion, pH of solution, dosage of photocatalyst and concentration of dye are variables that influence on the photoreactivity of nanocatalysts. In among ...
