The present study was undertaken to investigate whether the unusual accumulation of glycogen and its relationship to the process of cell growth, already shown in human colon tumor cell lines, also applied to malignant cell lines originating from other tissues. The glycogen content was measured during the exponential phase of growth in culture of 58 human tumor cell lines, most of them originati...

Sleep is essential for physical and niental health. In the last 15 years there has grown up the concept of the brain stem reticular activating system. Electroencephalographic studies have shown two qualitatively different and alternat ing kinds of sleep, the orthodox (“slowwave―, or “¿ fore-brain―) and the paradoxical (“hind brain―, “¿ rapid eye movement―, “¿ activated―, or ...

Tsukeda et a!. (13) recently published a report detailing experiments where the presumed cytotoxic action of sev eral antitumom agents was measured by a dye exclusion test. Cells were continuously treated with the agents for periods of 4 to 6 days and stained with 0.2% nigrosin every 12 hr. Cell viability was evaluated as a function of dye incorporation. These investigators claimed that their m...

â â â  â â  abstract: â  china and asean have been maintaining a relationship both cooperative and competitive in the textile trade. due to its labor intensive feature and high dependence on foreign trade , the textile trade has received much attention after the 2008 financial crisis. the customs data (classified by the hs code) from year 2006-2009 is employed to research the impact of the cris...

We developed a self-consistent screened-Korringa± Kohn± Rostoker (KKR) method in an ab initio tight-binding formulation. The reduction in numerical e€ ort in comparison with that required for the standard KKR method is achieved by the choice of a suitable reference system. Following the idea of Zeller et al. (1995, Phys. Rev. B, 52, 8807), reference systems with repulsive mu n-tin potentials o...

13-cis-Retinoic acid (RA) has been demonstrated to alter hemopoiesis in vitro. We compared proliferation and differentiation effects of RA to a synthetic retinoid, (E)-4-|2-(5,6,7,8-tetrahydro-5,5,8,8-terrainethyl-2naphthalenyl-l-propenyl|benzoicacid (TTNPB), on human normal bone marrow cells. TTNPB stimulated the in vitro growth of erythroidgranulocyte-macrophage progenitors and erythroid prog...

The effect of a long-acting somatostatin analogue SMS 201.995 (SMS; Sandoz) on basal and gastrin-stimulated growth of 4 human colon cancer lines was studied in vitro and in vico. Proliferation assay was done with overnight |75Se|selenomethionine uptake after 5 days of incubation. Gastrin concentrations used were 5e-10 M and le-7 M. SMS concentrations were from 2e-12 M to 2e-7 M. Cell lines LIM ...
