Innovazione per l'inclusione

«Social and Cultural Innovation» is a syntagma that has become of current usage among researchers due to the name chosen by the European Strategy Forum Research Infrastructures for the working group whose object are the research infrastructures that are primarily connected with Social Sciences and Humanities. Innovation means the creation of new products and services by bringing to the market a new idea. Economic growth turns on infrastructures, which provide access to services and knowledge, e.g. by overcoming the digital divide. It is up to the national governments to construct competencies that generate complexity. The current migrants and refugees crisis has made it clear with a terrific effectiveness that a most urgent objective is working out policies of social and cultural innovation to the advantage of new citizens that make them welcome in full dignity

The Role of Testosterone in Spermatogenesis: lessons from proteome profiling of human spermatozoa in testosterone deficiency

Testosterone is essential to maintain qualitative spermatogenesis. Nonetheless, no studies have been yet performed in humans to analyze the testosterone-mediated expression of sperm proteins and their importance in reproduction. Thus, this study aimed to identify sperm protein alterations in male hypogonadism using proteomic profiling. We have performed a comparative proteomic analysis comparing sperm from fertile controls (a pool of 5 normogonadic normozoospermic fertile men) versus sperm from patients with secondary hypogonadism (a pool of 5 oligozoospermic hypogonadic patients due to isolated LH deficiency). Sperm protein composition was analyzed, after peptide labelling with Isobaric Tags, via liquid chromatography followed by tandem mass spectrometry (LC-MS/MS) on an LTQ Velos-Orbitrap mass spectrometer. LC-MS/MS data were analyzed using Proteome Discoverer. Criteria used to accept protein identification included a false discovery rate (FDR) of 1% and at least 1 peptide match per protein. Up to 986 proteins were identified and, of those, 43 proteins were differentially expressed: 32 proteins were under-expressed and 11 were over-expressed in the pool of hypogonadic patients compared to the controls. Bioinformatic analyses were performed using UniProt Knowledgebase, and the Gene Ontology Consortium database based on PANTHER. Notably, 13 of these 43 differentially expressed proteins have been previously reported to be related to sperm function and spermatogenesis. Western blot analyses for A-Kinase Anchoring Protein 3 (AKAP3) and the Prolactin Inducible Protein (PIP) were used to confirm the proteomics data. In summary, a high-resolution mass spectrometry-based proteomic approach was used for the first time to describe alterations of the sperm proteome in secondary male hypogonadism. Some of the differential sperm proteins described in this study, which include Prosaposin, SMOC-1, SERPINA5, SPANXB1, GSG1, ELSPBP1, fibronectin, 5-oxoprolinase, AKAP3, AKAP4, HYDIN, ROPN1B, ß-Microseminoprotein and Protein S100-A8, could represent new targets for the design of infertility treatments due to androgen deficiency

Grapevine (Vitis vinifera L.) varietal assortment and evolution in the Marche region (central Italy)

14openInternationalItalian coauthor/editorItaly is one of the richest countries in terms of grapevine varietal assortment, and the Marche region in central Italy has an ancient winegrowing tradition. Increasing interest in autochthonous grapevine varieties prompted efforts to recover and identify local minor germplasm also in this region, and to search for pedigree relationships and determine the evolution of varietal assortment. In the present study this was done using nuclear and chloroplast microsatellite markers and SNP markers from the Vitis18kSNP chip. Eighteen new genotypes were found, of which seventeen belonged to well-known, less known and even unknown vines found to be specific to the Marche region. The rearranged pedigree highlighted the complex intertwining relationships between Marche varieties. Second-degree relationships were also derived. Some minor Marche varieties have increased the number of parent-offspring related members of Garganega, Sangiovese, Crepolino/Visparola and Sciaccarello, which are varieties already recognised as founders or recurrent parents of many Italian cultivars. Crepolino/Visparola was shown to be a key variety in the evolution of the Marche varietal assortment, having played the role of parent and grandparent, as explained by the presence of this genotype in the region in ancient times. Surprisingly, Semidano, a well-known Sardinian variety, played a clear role as parent or grandparent of three minor Marche varieties, testifying to its presence in central Italy in ancient times. Incrocio Bruni 54 was confirmed as an offspring of Sauvignon and Verdicchio, as declared by the breeder. The parentage of Lacrima was completed: this variety was found to be a spontaneous cross between Nera Rada and Aleatico. A dendrogram of genetic similarity clearly resembled the groups defined with the pedigree reconstruction and it gave an indication of the genetic similarity of the varieties excluded from the strictest parentage links.openCrespan, Manna; Migliaro, Daniele; Larger, Simone; Pindo, Massimo; Palmisano, Massimo; Manni, Alvise; Manni, Elisa; Polidori, Enzo; Sbaffi, Francesco; Silvestri, Quintilio; Silvestroni, Oriana; Velasco, Riccardo; Virgili, Settimio; Camilli, GiuseppeCrespan, M.; Migliaro, D.; Larger, S.; Pindo, M.; Palmisano, M.; Manni, A.; Manni, E.; Polidori, E.; Sbaffi, F.; Silvestri, Q.; Silvestroni, O.; Velasco, R.; Virgili, S.; Camilli, G

'In vitro' Effect of Different Follicle¿Stimulating Hormone Preparations on Sertoli Cells: Toward a Personalized Treatment for Male Infertility

Follicle-stimulating hormone (FSH), a major regulator of spermatogenesis, has a crucial function in the development and function of the testis and it is extensively given as a fertility treatment to stimulate spermatogenesis. We analyzed the effects of different FSH preparations (α-follitropin, β-follitropin, and urofollitropin) in combination with testosterone on porcine pre-pubertal Sertoli cells. To study the effect of the different FSH treatments in the Sertoli cell function we performed Real Time PCR analysis of AMH, inhibin B, and FSH-r, an ELISA assay for AMH and inhibin B, and a high-throughput comparative proteomic analysis. We verified that all three preparations induced a reduction of AMH in terms of mRNA and secreted proteins, and an increase of inhibin B in terms of mRNA in all the FSH formulations, while solely α-follitropin produced an increase of secreted inhibin B in the culture medium. Comparative proteomic analysis of the three FSH preparations identified 46 proteins, 11 up-regulated and 2 down-regulated. Surprisingly, the combination of testosterone with β-follitropin specifically induced an up-regulation of eight specific secreted proteins. Our study, showing that the three different FSH preparations induce different effects, could offer the opportunity to shed light inside new applications to a personalized reproductive medicine

Comparison of myocardial reperfusion between intracoronary versus intravenous cangrelor administration in patients undergoing primary percutaneous coronary intervention

Background: Myocardial reperfusion is the main target of treatment in patients with ST-segment elevation myocardial infarction (STEMI). The intracoronary administration of cangrelor bolus could favor a higher local drug concentration, favoring an earlier thrombotic resolution and a reduced distal micro-embolization. Methods: Seventy-one patients undergoing primary percutaneous coronary intervention (PCI) for STEMI: 37 treated with intracoronary and 34 with intravenous bolus administration of cangrelor. The primary endpoint was ST-elevation reduction (STR) ≥ 50% after 30 min from the end of the PCI. Other explorative reperfusion indices investigated were: STR ≥ 50% at 24 hours, STR ≥ 70% at 30 min, Thrombolysis In Myocardial Infarction frame count and the QT dispersion (QTd). Moreover, acute and subacute stent thrombosis, bleeding events and 30-day mortality have been evaluated. Results: More frequent STR ≥ 50% was observed in the intravenous cangrelor bolus group as compared to the intracoronary administration at 30 min (71.9% vs. 45.5%; p = 0.033), the difference was maintained 24 hours after PCI (87.1% vs. 63.6%; p = 0.030). STR ≥ 70% at 30 min was statistically more frequent in the intravenous bolus administration cohort (66.7% vs. 28.6% p = 0.02). At multivariable analysis, intravenous cangrelor administration was significantly related to STR ≥ 50% (odds ratio: 3.586; 95% confidence interval: 1.134–11.335; p = 0.030). The incidence of Bleeding Academic Research Consortium 3–5 bleedings was 15.5% and mortality was 4.2% without any significant difference between the two groups. Conclusions: In conclusion the results of the study do not show any advantages in the administration of intracoronary bolus of cangrelor in patients affected by STEMI and treated with primary PCI

Azimuthal anisotropy of charged jet production in root s(NN)=2.76 TeV Pb-Pb collisions

We present measurements of the azimuthal dependence of charged jet production in central and semi-central root s(NN) = 2.76 TeV Pb-Pb collisions with respect to the second harmonic event plane, quantified as nu(ch)(2) (jet). Jet finding is performed employing the anti-k(T) algorithm with a resolution parameter R = 0.2 using charged tracks from the ALICE tracking system. The contribution of the azimuthal anisotropy of the underlying event is taken into account event-by-event. The remaining (statistical) region-to-region fluctuations are removed on an ensemble basis by unfolding the jet spectra for different event plane orientations independently. Significant non-zero nu(ch)(2) (jet) is observed in semi-central collisions (30-50% centrality) for 20 <p(T)(ch) (jet) <90 GeV/c. The azimuthal dependence of the charged jet production is similar to the dependence observed for jets comprising both charged and neutral fragments, and compatible with measurements of the nu(2) of single charged particles at high p(T). Good agreement between the data and predictions from JEWEL, an event generator simulating parton shower evolution in the presence of a dense QCD medium, is found in semi-central collisions.
