Pro-inflammatory, Pleiotropic, and Anti-inflammatory TNF-α, IL-6, and IL-10 in Experimental Porcine Intervertebral Disk Degeneration

2009

The aim of this study was to check the balance between tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and interleukin-10 (IL-10) in well-developed end-stage disk disease in the disk itself as well as in paradiskal spine. In 6 domestic pigs the cranial bony end plate of the L4 vertebra was perforated to the nucleus pulposus. At 3 months the degenerated experimental and contiguous control disks, together with the adjoining bony and cartilaginous vertebral end plates, bone marrow, and spinal ligaments, were excised and used for immunohistochemical analysis. In general, there were more TNF-α and in particular IL-10 positive cells in the degenerated disks than in the control disks, where…

Economic analysis and energy valorisation of by-products of the wine supply chain: the case of the 'Mamertino wine PDO'

2018

The paper reports the analysis of biomass derived from maintenance of a vineyard, to assess its potential as an alternative energy source, instead of the usual disposal of the wine supply chain’s residuals. The site studied is within the province of Messina, Sicily, in the area of Mamertino wine PDO, a wine of superior quality. The analysis suggests that use of this kind of biomass may allow a fossil fuel such as liquefied petroleum gas (LPG) to be replaced by a wine wood chip biomass boiler, thus meeting economic and environmental criteria by reason of recycling for sustainability.

Biodiversity and oenological attitude of Saccharomyces cerevisiae strains isolated in the Montalcino district: biodiversity of S. cerevisiae strains …

2020

ABSTRACT The biodiversity of Saccharomyces cerevisiae was studied in the Montalcino area (Italy). Two wineries were involved in the study, which compared the genotypic and oenological characteristics of the S. cerevisiae strains isolated in spontaneous fermentations. After isolation yeasts were identified by 26S rRNA gene sequence analysis, and S. cerevisiae strains were characterized through interdelta sequence analysis (ISA). Oenological tests were performed in synthetic grape must by varying the magnitude of the main wine-imiting factors. The evolution of alcoholic fermentation was monitored by measuring sugar consumption and flow cytometry. The results revealed the prevalence of S. cere…

Preservation of Microbial Strains in the Wine Industry

2011

Publisher Summary This chapter provides a general description of the most commonly used methods for the preservation of microbial strains. Long-term preservation methods are considered the most appropriate option wherever possible, since they involve stopping the growth of the microbial cells and keeping them in a viable state. This guarantees maximum genetic stability by preventing the appearance of successive generations. Nevertheless, the possibility that the preparation method itself leads to changes cannot be ruled out. There are two preservation methods belonging to this group: freezing and lyophilization. In the first long-term preservation method, the cells are frozen suspended in a…

Transcriptomic and proteomic insights of the wine yeast biomass propagation process

2010

Transcriptome and proteome profiles have been established for the commercial wine yeast strain T73 during an important industrial process: yeast biomass propagation. The data from both analyses reveal that the metabolic transition from fermentation to respiration is the most critical step in biomass propagation. We identified 177 ORFs and 56 proteins among those most expressed during the process, thus highlighting cell stress response, mitochondrial and carbohydrate metabolism as the most represented functional categories. A direct correlation between mRNA changes and protein abundance was observed for several functional categories such as tricarboxylic acid cycle proteins, heat shock prote…

Proteomic profiling of German Dornfelder grape berries using data-independent acquisition

2017

Grapevine is one of the most important fruit plants throughout the world. Sequencing of the grape genome in 2007 enabled in-depth analyses of the grape proteome. Whereas many studies addressed changes in proteomic composition of grapes during ripening, we focused on the proteome of mature grape berries from Dornfelder, a characteristic red wine grape for Germany. Current data-independent acquisition proteomics technology enables the analysis of proteomic compositions in a degree of accuracy that was unreachable only a few years ago. Using a label-free proteomics approach, we quantified 712 proteins in mature Dornfelder grape berries, of which 650 could be annotated by the Blast2GO software.…

Platinum and rhodium in wine samples by using voltammetric techniques

2017

For the first time, the concentrations of Pt and Rh in 42 different alcoholic beverages (white and red wines, vodka and brandy) produced in Italy, Malta and Gozo were investigated. Only the voltammetric techniques, in particular, differential Pulse Voltammetry (DPV/a) and Adsorptive Stripping Voltammetry (AdSV) were used for the determination of Pt and Rh respectively. Accuracy was tested with standard addition method and recoveries ranged from 90% to 98%. In analyzed wine samples, Pt and Rh concentrations are in the ranges from 3 to 470 μg L− 1and from 0.0006 to 0.36 μg L− 1respectively. We found a Pt/Rh ratios ranged from 37 to 180,000, in quite disagreement with the ratio in …

THE PREMIUM PRICE FOR ITALIAN RED WINE QUALITY ATTRIBUTES IN THE JAPANESE MARKET

2015

In this paper we apply the hedonic price model in order to estimate implicit price for the main objective characteristics appearing on the label of Italian wines sold in Japan, easier to identify than sensory attributes by consumers. In this paper, the wine searcher dataset has been used in order to select the retailer price and the research score for 829 wines, for each of which we have observed information about their geographical origin, vintage, grape varieties, vintage, and the alcohol degree. Our results indicate that international grape varieties, alcohol content and the year of production explain the major part of price difference. On the other hand, the origin appellations linked t…
