Housing rental prices: Data from a central urban area of Naples (Italy).

The database presented was collected to analyze the housing rental prices for a central urban area of Naples (Italy) during 2016. The data sample relates to 64 housing units located in "Santa Lucia" and "Riviera di Chiaia" neighborhoods. It provides significant information on the urban structure of these neighborhoods. The variables are indicators elaborated from official data sources: real estate rental price, commercial area, maintenance status, number of floor level of housing unit, geographical position. The geographical position is expressed assigning a prefixed sequence of characters to each housing unit, so as to classify every housing unit as falling to a defined sub-area with homogeneous values. The urban area considered is subdivided in five sub-areas. The five subzones are homogeneous in terms of services and infrastructure qualification.

Effect of red wine antioxidants and minor polyphenolic constituents on endothelial progenitor cells after physical training in mice.

Circulating endothelial progenitor cells (EPCs) play a significant role in regeneration of damaged blood vessels. Levels and functional activities of EPCs are noticeable altered by risk factors for coronary heart disease (CHD) and compounds that can prevent or ameliorate EPC dysfunction are currently of special clinical interest. Here, we evaluate the effects of red wine (RW) on EPCs in C57BL/6J mice subjected to physical exercise. FACS computed counting showed a significant increase of EPC number (P<0.05) in mice after short-term supplementation with RW. VEGF serum concentration was significantly increased by physical training in the presence or absence of RW supplementation (P<0.001). These in vivo observations support previous in vitro observation of the beneficial effect of RW in the modulation of EPC levels.

Comparison between total endothelial progenitor cell isolation versus enriched Cd133+ culture.

Endothelial progenitor cells (EPCs) play a role in endogenous neovascularization of ischaemic tissues. Isolation and characterization of EPCs from circulating mononuclear cells are important for developing targeted cellular therapies and reproducibility of data are the major scientific goals. Here we compared two currently employed isolation methods, i.e. from total peripheral blood mononuclear cells (PBMCs) and from enriched CD133(+) cells, by defining the cell morphology and functional activities. We show that EPCs from cultured PBMCs resulted in an adherent population of 23% +/- 4% merged cells positive for Dil-Ac-LDL and lectin, whereas the percentage of double positive cells in cultured CD133(+) enriched cells was 50% +/- 7% (P < 0.01). These data were obtained through a novel and a more complete method of analysis of cell calculations (specifically by dividing each microscope field into 120 subfields). When stimulated with tumour necrosis factor alpha (TNF)-alpha and glucose, cell number was reduced in EPCs from total PBMCs and, more consistently, in CD133(+) enriched cells. However, both cultured total PBMCs and CD133(+) enriched cells respond similarly to TNF-alpha or glucose-induced p38-phosphorylation. EPCs from both procedures show similar results in terms of phenotype and response to modulators of their functional activities. However, when the cell phenotype of CD133(+) enrichment-derived cells was compared with that of cells from the total PBMC, a significant increase in CD133(+) expression was observed (P < 0.01) This may have relevance during intervention studies using cultured EPCs.
