The source of small amounts of touch DNA, which is transferred from the skin to an object when it is handled or touched, could be an issue in the forensic analysis of criminal cases. Here, we performed an extended evaluation of skin- or sweat-characteristic mRNAs to investigate their usability to infer whether an object has been handled or touched by someone. First, we compared the expression levels of candidate genes between skin swabs and other body fluids by quantitative RT-PCR analysis. Among the analyzed genes, corneodesmosin (CDSN), late cornified envelope 1C (LCE1C), filaggrin (FLG), desmocollin 1, and dermcidin were selected for further analysis on the basis of their specificities and sensitivities...

Porcine Reproductive and Respiratory Syndrome (PRRS) is an elusive model of host/virus relationship in which disease is determined by virus pathogenicity, pig breed susceptibility and phenotype, microbial infectious pressure and environmental conditions. Successful disease control in PRRS-endemic Countries corresponds to "stability", i.e. a condition with no clinical signs of PRRS in the breeding-herd population and no viremia in weaning-age pigs. The aim of this work was to compare the profile and time-course of humoral and cell-mediated immunity in stable and unstable herds, respectively...

Currently, immune checkpoint blockade against members of the B7/CD28 family is being used as a new molecular-targeted therapy, in patients with unresectable advanced or recurrent gastric cancer. Although human endogenous retrovirus-H long terminal repeat-associating protein 2 (HHLA2) is a novel molecule of the B7/CD28 family, the clinical impact of its expression remains uncertain in gastric cancer. Consequently, we examined HHLA2 expression in blood specimens from patients with gastric cancer, and investigated the relationship between its expression and clinicopathological factors to assess its potential power as a prognostic blood predictor...
