Identification and Molecular Characterization of Novel Mycoviruses in and Non- Yeasts of Oenological Interest.

Wine yeasts can be natural hosts for dsRNA, ssRNA viruses and retrotransposon elements. In this study, high-throughput RNA sequencing combined with bioinformatic analyses unveiled the virome associated to 16 and 8 non- strains of oenological interest. Results showed the presence of six viruses and two satellite dsRNAs from four different families, two of which- and -were not reported before in yeasts, as well as two ORFan contigs of viral origin.

Manual treatment for kidney mobility and symptoms in women with nonspecific low back pain and urinary infections.

Context: Recent studies have suggested a connection between low back pain (LBP) and urinary tract infections (UTI). These disturbances could be triggered via visceral-somatic pathways, and there is evidence that kidney mobility is reduced in patients suffering from nonspecific LBP. Manual treatment of the perinephric fascia could improve both kidney mobility and LBP related symptoms.

Biodiversity of indigenous Saccharomyces populations from old wineries of south-eastern Sicily (Italy): preservation and economic potential.

In recent years, the preservation of biodiversity has become an important issue. Despite much public discussion, however, current practices in the food industry seldom take account of its potential economic importance: on the contrary, the introduction of industrialized agriculture practices over large areas has often resulted in a dramatic reduction in biodiversity.In this paper, we report on the remarkable degree of biodiversity in the wine yeast populations naturally present in a small area of Sicily (Italy) where traditional (non-industrial) winery practices are still in place.

Increasing voltage gradient electrophoresis of DNA.

We developed a method which allows electrophoretic fractionation of DNA in an agarose matrix according to an increasing current gradient, using a previously designed [R. Barbieri, V. Izzo, M.

Mating types in yeast, vomeronasal organ in rodents, homosexuality in humans: does a guiding thread exist?

Pheromones and their receptors are the molecules used by very different organisms in order to join two haploid cells. It happens evidently in yeast, since the two blending haploid cells are also the two mating organisms, whereas in rodents pheromone receptors are the triggers of the vomeronasal system which, supervising sexual behaviors, is responsible for copulation and therefore for fertilization. The debate is still open about the real significance of pheromones in humans but a working vomeronasal organ, able to recognize pheromones of the same sex, could be the simplest biological explanation of homosexuality.
