Summary form only given, as follows. The reliability of medium voltage shielded power cables in the generating station environment has been a critical issue for nuclear operations for many years, ...principally from the perspective of safety-related systems. This paper describes the approach to cable condition assessment employed in nuclear. and conventional generating stations, for both oil-paper and solid extruded polymeric cables.
Mutational status of immunoglobulin heavy-chain variable-region (IgVH) genes, along with CD38 expression, is a prognostic marker in B-cell chronic lymphocytic leukemia (B-CLL). Configuration of IgVH ...genes displaying > 2% mismatch has been shown to correlate with longer survivals. In a series of 64 B-CLLs, we failed to confirm the prognostic value of the IgVH gene mutational status by using the suggested cutoff. However, the IgVH mutational status maintained its prognostic value only when evidence of antigen-driven selection could be documented. This was accomplished by applying statistical methods aimed at evaluating a significant skewing of replacement mutations from framework to complementary determining regions, as it occurs during germinal center differentiation of B cells. These data caution against wide application of the 2% somatic mutation cutoff as a prognostic determinant without demonstration of antigen-driven selection.
We have studied smoking habit in the sample enrolled in the ten year follow-up of the "Pordenone Study on the Precursors of Atherosclerosis in Childhood". The response rate at ten year follow-up was ...very high (about 90%). Prevalence of smoking is 45.1% among males and 25.6% among females. Males and females aged 23 present a prevalence of smokers higher than the other groups while the group aged 26 smoke less. Males began to smoke at 16.4 years, females at 16.7. Mean daily consumption is 12.6 cigarettes among males, and 5.0 among females. Juvenile experimentation with cigarettes and juvenile smoking habit are strong predictors to smoke ten years later; while parental smoking behaviour is not so influential. Therefore we conclude that smoking habit acquired in youngs has a high probability to be maintained in adults, remarking the importance of planning a preventive intervention as early as possible.
