A New Technique for Exploitation of Wine Lees

Abstract The possibility of obtaining high quality wine from lees could increase value added for farm productions. A new technique introduced on an industrial scale to provide wine from lees of different origin is presented. After racking, the lees are collected in an innovative steel system and processed in controlled conditions of temperature, micro-oxigenation and cycles of remixing. During the treatment, an increase of color intensity, total polyphenols and total polysaccharides of wine from the lees was detected while the hue was stable. The obtained results indicate that the proposed method could be an effective tool for exploitation of the lees on winery scale. The new technology strongly reduced the time necessary to reach positive oenological objectives

Characterisation of Extracts Obtained from Unripe Grapes and Evaluation of Their Potential Protective Effects against Oxidation of Wine Colour in Comparison with Different Oenological Products

Unripe grapes (UGs) are a waste product of vine cultivation rich in natural antioxidants. These antioxidants could be used in winemaking as alternatives to SO(2). Three extracts were obtained by maceration from Viognier, Merlot and Sangiovese UGs. The composition and antioxidant activity of the UG extracts were studied in model solutions at different pH levels. The capacity of the UG extracts to protect wine colour was evaluated in accelerated oxidation tests and small-scale trials on both red and white wines during ageing in comparison with sulphur dioxide, ascorbic acid and commercial tannins. The Viognier and Merlot extracts were rich in phenolic acids while the Sangiovese extract was rich in flavonoids. The antioxidant activity of the extracts and commercial tannins was influenced by the pH. In the oxidation tests, the extracts and commercial products showed different wine colour protection capacities in function of the type of wine. During ageing, the white wine with the added Viognier UG extract showed the lowest level of colour oxidation. The colour of the red wine with the UG extract evolved similarly to wine with SO(2) and commercial tannins. The obtained results indicated that natural and healthy UG extracts could be an interesting substitute for SO(2) during wine ageing

A postmarket safety comparison of 2 vaccination strategies for measles, mumps, rubella and varicella in Italy

It is strategically important to monitor the safety profile of vaccination schedules in order to achieve and maintain high levels of coverage. We analyzed the cohort of individuals actively invited for measles, mumps, rubella and varicella (MMRV) vaccination in the Veneto region (north-east Italy) from 8/1/2013 to 7/31/2014, assessing the onset of adverse events (AE) relating to 2 different vaccination strategies for MMRV (MMR+V vs MMRV). During the vaccination session at 14\ua0months old, parents were given a form for recording local and systemic reactions to vaccinations for 4\ua0weeks afterwards. Overall, 12,288 forms were returned, and 84.6% of them were included in this analysis (5,130 relating to MMR+V and 5,265 to MMRV); 37.3% of the sample reported no AEs, with no difference between the 2 groups. Local reactions were more common in the MMR+V group (9.6% vs 2.9%; RR 3.33; 95% CI 2.79-3.98), while there was no difference in general reactions between the 2 groups (50% MMR+V vs 52% MMRV). The events most often reported were "fever <39.5\ub0C," which was more frequently associated with the MMRV strategy (p<0.001), and "skin blotches and marks," which occurred more often in the MMR+V group (p<0.001). Reports of "fever 6539.5\ub0C" were equally distributed between the 2 groups. Sixteen cases of febrile seizures were reported (0.14% in the MMR+V group and 0.17% in the MMRV group). Similar safety profiles were identified for the 2 vaccination strategies. Although the method used to record reactions to vaccination demanded considerable resources, it enabled important information to be collected on parents' perception of the AEs occurring in response to their child's vaccination

Metabolic Syndrome and All-Cause and Cardiovascular Mortality in an Italian Elderly Population: The Progetto Veneto Anziani (Pro.V.A.) Study

OBJECTIVE—The purpose of this study was to explore the association of metabolic syndrome and each of its components with all-cause and cardiovascular mortality in a general Italian elderly population

Viable Newcastle Disease Vaccine Strains in a Pharmaceutical Dump

To assess the viability of discarded and buried vaccine strains, we examined vaccines that had been buried for >20 years in an industrial waste dump in the city of Milan, Italy. Viability results showed potential biological risk associated with uncontrolled burial of pharmaceutical industry waste, including some live vaccines

Social Perception of Reconstruction following Orbital Exenteration

Background: Orbital exenteration, the removal of the entire globe, eyelids, and orbital content, is indicated in extensive neoplastic disease involving the orbital region. Although a functional reconstruction of orbital exenteration defects is mandatory, aesthetic concerns need to be considered. Facial disfigurement following reconstructive surgery often leads to great discomfort and social retirement, which can limit social interaction. The aim of this study was to explore how the society perceives the aspect of patients who underwent orbital exenteration and subsequent reconstruction, comparing two different types of reconstruction: standard anterolateral thigh (ALT) or "sandwich" fascial ALT (SALT) free flap. Methods: An online survey was created based on four questions regarding the perception of reconstruction (discomfort at looking at that patient, perception of unhealthiness, hypothesis of social life impairment, etc); five possible answers were provided, ranging from "completely" to "not at all." The survey was administered to the general population and to medical students. Results: In total, 255 people participated to the survey (130 medical students and 125 people of the general population); a total of 245 surveys were considered eligible (10 were incomplete and then discharged). Statistical significance was found (P &lt; 0.001) regarding the better overall appearance of the SALT group over the ALT one. Conclusions: After analysis, the surgical outcome after SALT reconstruction has been found to be less disruptive in both groups, due to a reduced scar burden and a more pleasant orbital pocket. Our results encourage more research in the field of postexenteration reconstruction to achieve more aesthetic and social acceptability

In Celiac Disease, a Subset of Autoantibodies against Transglutaminase Binds Toll-Like Receptor 4 and Induces Activation of Monocytes

BACKGROUND: Celiac disease is a small intestine inflammatory disorder with multiple organ involvement, sustained by an inappropriate immune response to dietary gluten. Anti-transglutaminase antibodies are a typical serological marker in patients with active disease, and may disappear during a gluten-free diet treatment. Involvement of infectious agents and innate immunity has been suggested but never proven. Molecular mimicry is one of the mechanisms that links infection and autoimmunity. METHODS AND FINDINGS: In our attempt to clarify the pathogenesis of celiac disease, we screened a random peptide library with pooled sera of patients affected by active disease after a pre-screening with the sera of the same patients on a gluten-free diet. We identified a peptide recognized by serum immunoglobulins of patients with active disease, but not by those of patients on a gluten-free diet. This peptide shares homology with the rotavirus major neutralizing protein VP-7 and with the self-antigens tissue transglutaminase, human heat shock protein 60, desmoglein 1, and Toll-like receptor 4. We show that antibodies against the peptide affinity-purified from the sera of patients with active disease recognize the viral product and self-antigens in ELISA and Western blot. These antibodies were able to induce increased epithelial cell permeability evaluated by transepithelial flux of [(3)H] mannitol in the T84 human intestinal epithelial cell line. Finally, the purified antibodies induced monocyte activation upon binding Toll-like receptor 4, evaluated both by surface expression of activation markers and by production of pro-inflammatory cytokines. CONCLUSIONS: Our findings show that in active celiac disease, a subset of anti-transglutaminase IgA antibodies recognize the viral protein VP-7, suggesting a possible involvement of rotavirus infection in the pathogenesis of the disease, through a mechanism of molecular mimicry. Moreover, such antibodies recognize self-antigens and are functionally active, able to increase intestinal permeability and induce monocyte activation. We therefore provide evidence for the involvement of innate immunity in the pathogenesis of celiac disease through a previously unknown mechanism of engagement of Toll-like receptor 4
