Unraveling the complex trait of low temperature adaptation in the wine yeast Saccharomyces cerevisiae
2016
1. Introducción Se cree que las uvas fueron domesticadas entre el Mar Negro e Irán durante el periodo del 7000-4000 aC. Las primeras evidencias de elaboración de vino provienen de la presencia de ácido tartárico en un tarro antiguo que data de 5400 - 5000 aC en el yacimiento neolítico de Tepe en Mesopotamia y de los restos de la extracción del zumo de uva en el yacimiento neolítico de Dikili Tash en Grecia (5000 aC). La colonización de los romanos extendió la elaboración del vino por todo el Mediterráneo; en el 500 aC el vino ya se producía en Italia, Francia, España, Portugal y el norte de África. Posteriormente también fue extendido a los Balcanes, Alemania y otras partes del norte de Eur…
A metabolomic study of yeast/bacteria interactions
2015
As a complex microbial ecosystem, wine is a particularly interesting model for studying interactions between microorganisms. Contact-independent interactions (indirect interactions) between the yeast Saccharomyces cerevisae and the lactic acid bacterium Oenococcus oeni have a direct effect on malolactic fermentation (MLF), induction and completion, which is an important factor in wine quality. Yeast strains could be classified as MLF+ phenotype if it usually stimulates the bacterial growth or MLF- in the opposite case. The known metabolites that stimulate or inhibit the MLF cannot always explain the phenotypic distinction. In this work, a multidisciplinary workflow combining non-targeted me…
Cooperatives' performance relative to investor-owned firms: a non-distorted approach for the wine sector
2021
PurposeThis study aims to investigate whether significant performance differences between cooperatives and investor-owned firms (IOFs) may exist.Design/methodology/approachBased on data from a sample of Italian wine firms for the period from 2009 to 2018, an adjusted measure of performance called earnings before interests, taxes, depreciations and amortizations gross the raw materials cost was adopted to consider the different objectives of cooperatives relative to those of IOFs.FindingsEmpirical evidence shows that in the context under analysis, cooperatives have performed better than IOFs.Originality/valueDespite the theoretical literature suggesting that the cooperative form of organizat…
Latvijas loma starptautiskajā vīna industrijā.
2017
Starptautiskā vīna industrija ir ļoti komplicēta nozare, kas atšķiras no jebkura cita sektora, un ir uzrādījusi lielas izmaiņas pēdējo 20 gadu laikā. Latvijas attīstība, neatkarības atgūšana, ieiešana Eiropas Savienībā dažādu faktoru ietekmē ir mainījusi Latvijas lomu starptautiskajā vīna tirgū, kas ir līdz šim neizpētīts jautājums. Bakalaura darba mērķis ir identificēt galvenās tendences starptautiskajā vīna tirgū, pētīt vīna re-eksportētāju lomu starptautiskajā sadales kanālā un identificēt Latvijas pozīcijas tajā, pētot to attīstību laika gaitā un salīdzinot ar globālajām tendencēm. Bakalaura darba ietvaros tiks apskatīta pieejamā literatūra par pasaules vīna industriju un tās tendencēm,…
The communicative power of an extreme territory – the Italian island of Pantelleria and its passito wine
2018
Purpose This paper aims to examine how Pantelleria’s wineries communicate the extreme territory of Pantelleria through its passito wine and whether this may be a value added for consumers. Specifically examines which dimensions of communication are effectively used by wineries to stimulate, in wine consumers, emotions that link passito wine with the territory of Pantelleria. Design/methodology/approach All websites of wineries producing passito wine in Pantelleria were analyzed using the adaptation, goal-attainment, integration and latent pattern maintenance (AGIL) scheme for measuring communication dimensions. Findings Results suggest that wineries and stakeholders should apply territory-…
The Wine Influencers: Exploring a New Communication Model of Open Innovation for Wine Producers—A Netnographic, Factor and AGIL Analysis
2020
Wine Influencers (WIs) represent a new type of independent third party endorsers that are progressively establishing themselves within social networks. This study analyzes the characteristics of the activity of WIs and the communication model used via Instagram. Netnographic Analysis, Factor Analysis and AGIL methods were applied. The results show five Key-findings within specific relationships established during discussions: advice from Wine Influencers and generalized reciprocity in relationships
The impact of the receptor binding profiles of the vascular endothelial growth factors on their angiogenic features
2013
Abstract Background Vascular endothelial growth factors (VEGFs) are potential therapeutic agents for treatment of ischemic diseases. Their angiogenic effects are mainly mediated through VEGF receptor 2 (VEGFR2). Methods Receptor binding, signaling, and biological efficacy of several VEGFR2 ligands were compared to determine their characteristics regarding angiogenic activity and vascular permeability. Results Tested VEGFR2 ligands induced receptor tyrosine phosphorylation with different efficacy depending on their binding affinities. However, the tyrosine phosphorylation pattern and the activation of the major downstream signaling pathways were comparable. The maximal angiogenic effect stim…
Renal transplantation by automatic anastomotic device in a porcine model
2015
Automatic vascular staplers for vascular anastomoses in kidney transplantation may dramatically reduce the operative time and, in particular, warm ischemia time, thus increasing the outcome of transplantation. Ten pigs underwent kidney auto-transplantation by automatic anastomotic device. Kidneys were collected by laparotomy with selective ligations at the renal hilum and perfused with cold storage solution. To overcome the shortage in length of renal hilum, a tract of the internal jugular vein was harvested to increase the length of the vessels. The anastomoses were totally performed by the use of the anastomotic device. On 10 kidney transplants, nine were successful and no complications o…

Absence of Toxoplasma gondii in 100% Iberian products from experimentally infected pigs cured following a specific traditional process.
2020
Infection with Toxoplasma gondii in humans has usually been related to the consumption of raw, undercooked or cured meat. Our study is based on the detection of T. gondii in cured legs and shoulders made from 100% Iberian sows fed mainly with acorn and raised as outdoor livestock in Aracena (Spain), which having been elaborated following a specific curing process (time period and location). An outdoor farm with a total of 636 animals was studied, showing a seroprevalence of 10% for the parasite T. gondii. Twenty individuals were chosen to be experimentally infected and slaughtered 60 days post-infection. Their legs and shoulders were processed to make 100% Iberian ham legs and shoulders. Th…
