T-cell prolymphocytic leukemia is associated with deregulation of oncogenic microRNAs on transcriptional and epigenetic level.

Deregulation of micro(mi)-RNAs is a common mechanism in tumorigenesis. We investigated the expression of 2083 miRNAs in T-cell prolymphocytic leukemia (T-PLL). Compared to physiologic CD4+ and CD8+ T-cell subsets, 111 miRNAs were differentially expressed in T-PLL.

[Bactericidal effects of antiseptic gypsum].

In tests with plaster models we inspected the antibacterial effect of the dental plasters Dento-rock and Dento-dur. The results show, that models consisting of plaster that contains Chloramin T 80 were free of bacteria, even when produced from bacterial contaminated alginate impressions. After separation of the plaster models from the alginate impressions, a bactericide effect could be traced to a layer of 220 microns below the surface of the alginate.
