The Streptomyces griseus 70S ribosome fraction was analyzed by radical-free and highly reducing two-dimensional (RFHR 2D) gel electrophoresis and mass spectrometry. Among the 60 putative ribosomal proteins that are encoded by the S. griseus genome, 48 were identified in the 70S ribosome fraction prepared from mycelia grown in liquid culture for 12, 36, and 48 h. Ribosomal protein S3 was detecte...

The lipid class compositions of subcellular fractions of SV40-transformed mouse fibroblasts derived from the logarithmic and stationary growth phase were compared. Cell populations of the stationary growth phase showed a relative decrease of the protein content and an increase of triglycerides and alkoxydiglycerides which could be located in the non-sedimenting fraction and in the nuclei and mi...

conclusion the cv value correlated more closely with low lvef and more accurately indicated an enlarged heart than ca or ctr. this may be due to the fact that an anteroposterior measurement of heart size is included in the former but not the latter two measurements. these study results may help quantify left heart enlargement with greater accuracy than may be obtained from standard cxr. backgro...

in this article cuo/water nanofluid was synthesized by using polyvinylpyrolidone (pvp) as the dispersant.  thenanofluid stability period and the heat transfer enhancement were determinedby measuring the thermal conductivities. to study the nano-fluid stability, zeta (ζ) potential, and absorbency were measured under different ph values and pvp surfactant concentrations; also thermal conductivity...

The growth of Leuconostoc citrovorum ML 34, an isolate associated with the malo-lactic fermentation of wine, was stimulated in part by grape, orange, cabbage, and tomato juices. The stimulatory activity of tomato serum was associated with the carbohydrate fraction. Further purification of the fraction showed that fructose was the factor responsible for initiating growth. In addition to fructose...

1. The hypodermic administration of tethelin increases markedly the rate of growth of the primary tumor and the tendency to form metastases in rats inoculated with carcinoma, in this, as in other respects, reproducing the action of the whole anterior lobe of the pituitary body. 2. Other alcohol-soluble extractives of the anterior lobe of the pituitary body, with the exception of the lecithin fr...
