The effects of loss of Y chromosome on male health.

Loss of Y chromosome (LOY) is the most commonly occurring post-zygotic (somatic) mutation in male individuals. The past decade of research suggests that LOY has important effects in shaping the activity of the immune system, and multiple studies have shown the effects of LOY on a range of diseases, including cancer, neurodegeneration, cardiovascular disease and acute infection. Epidemiological findings have been corroborated by functional analyses providing insights into the mechanisms by which LOY modulates the immune system; in particular, a causal role for LOY in cardiac fibrosis, bladder cancer and Alzheimer disease has been indicated.

Establishing, evaluating and monitoring analytical quality in the traceability era.

Poor analytical quality may be the bane of medical use of laboratory tests, and the fight against excessive analytical variability presents a daily struggle. Laboratories should prioritize the perspectives and needs of their customers (the patients and healthcare personnel). Among them, comparability of results from the same patient sample when measured by different laboratories using different diagnostic (IVD) medical devices is a logical priority to avoid result misinterpretation and potential patient harm.

Electron Transport in Soft-Crystalline Thin Films of Perylene Diimide Substituted with Swallow-Tail Terminal Alkyl Chains.

We have examined the structural and electron transport properties of a swallow-tailed ,'-bis(1-heptyloctyl)-perylene-3,4:9,10-bis(dicarboximide) () in thin films. A comprehensive analysis of material with the use of X-ray scattering methods evidenced the appearance of a new soft-crystalline mesophase that was induced by thermal processing of the swallow-tail PDI derivative. By combining electrical measurements with grazing-incidence wide-angle X-ray scattering (GIWAXS), we show that these morphological changes of thin films boost their charge transport in the organic field-effect transistor (OFET) configuration.
