The sequential or co-inoculation of grape must with non-Saccharomyces yeast species and Saccharomyces cerevisiae wine yeast strains has recently become a common practice in winemaking. The procedure intends to enhance unique aroma and flavor profiles of wine. The extent of the impact of non-Saccharomyces strains depends on their ability to produce biomass and to remain metabolically active for a sufficiently long period. However, mixed-culture wine fermentations tend to become rapidly dominated by S. cerevisiae, reducing or eliminating the non-Saccharomyces yeast contribution...

REVIEW
Cho-Won Kim, Kyung-A Hwang, Kyung-Chul Choi
BACKGROUND: Increased epithelial-mesenchymal transition (EMT) and cell migration and invasion abilities of cancer cells play important roles in the metastatic process of cancer. Resveratrol is a stilbenoid, a type of natural polyphenol found in the skin of grapes, berries, and peanuts. A number of experiments have examined resveratrol's ability to target diverse pathways associated with carcinogenesis and cancer progression. PURPOSE: This article aims to present updated overview of the knowledge that resveratrol and its metabolites or analogs have the potential to inhibit metastasis of cancer via affecting many signaling pathways related with EMT, cancer migration, and invasion in diverse organs of the body...

Fruit wines contain a wide range of phenolic compounds with biological effects, but their composition and potential benefits to human health have been studied to the much lesser extent compared to grape wines. The aim of this research is to study the phenolic profile of different types of fruit wines and to evaluate their antioxidant and biological potential. Commercially available fruit wines from blackberry, cherry, raspberry, blackcurrant, strawberry and apple produced in Croatia were analyzed. To the best of our knowledge, this study represents the first comprehensive screening of Croatian fruit wines...

This study evaluates the influence of Lachancea thermotolerans on low-acidity Airén grape must from the south of Spain. For this purpose, combined fermentations with Lachancea thermotolerans and Saccharomyces cerevisiae were compared to a single fermentation by S. cerevisiae. Results of all developed analyses showed significant differences in several parameters including acidity, population growth kinetics, concentration of amino acids, volatile and non-volatile compounds, and sensorial parameters. The Airén wine quality increased mainly due to the acidification by L...

Piceatannol, a resveratrol metabolite, is a phenolic compound found in red wine and grapes. We investigated the effect of piceatannol on renal fibrosis and histone deacetylase (HDAC) expression in a mouse model of unilateral ureteral obstruction (UUO). Fibrosis was established by UUO and piceatannol was intraperitoneally injected for 2 weeks. Piceatannol suppressed extracellular matrix (ECM) protein deposition including collagen type I and fibronectin as well as connective tissue growth factor (CTGF) and α-smooth muscle actin (α-SMA) in UUO kidneys...

Fibromyalgia syndrome (FMS), a chronic musculoskeletal pain condition, is often accompanied by fatigue. In this study, inspired by narrative approaches to health and illness, we explore how women who have regained their health after FMS describe tiredness along a storyline from before they fell ill, through their illness, recovery process, and present-day health. The data derive from qualitative interviews with eight Norwegian women who previously suffered from FMS but who no longer had the condition at the time of interview...

Erhu Li, Ramón Mira de Orduña
Acetaldehyde strongly binds to the wine preservative SO2 and, on average, causes 50-70 mg l(-1) of bound SO2 in red and white wines, respectively. Therefore, a reduction of bound and total SO2 concentrations necessitates knowledge of the factors that affect final acetaldehyde concentrations in wines. This study provides a comprehensive analysis of the acetaldehyde production and degradation kinetics of 26 yeast strains of oenological relevance during alcoholic fermentation in must under controlled anaerobic conditions...

The impact of water deficit on berry quality has been extensively investigated during the last decades. Nonetheless, there is a scarcity of knowledge on the performance of varieties exposed to a combination of high temperatures/water stress during the growing season and under vineyard conditions. The objective of this research was to investigate the effects of two irrigation regimes, sustained deficit irrigation (SDI, 30% ETc) and regulated deficit irrigation (RDI, 15% ETc) and of two cluster positions within the canopy (east- and west-exposed sides) on berry ripening in red Aragonez (Tempranillo) grapevines...

ETHNOPHARMACOLOGICAL RELEVANCE: This paper has two overarching aims: (1) presenting the results of studying the Albacete tariff of medicines of 1526 and (2) broadly analyzing the origin and influences of medicinal traditional knowledge in the region of Albacete, Spain. We use historical and modern literature that may have influenced this knowledge. Our primary goal was to determine the ingredients used in the pharmacy in the 16th century CE in Albacete through the analysis of the tariff, and our secondary goal was to investigate until when ingredients and uses present in pharmacy and herbals persisted in later periods...

Oxidative stress and mitochondrial dysfunction play crucial role in the dopaminergic neurons death, which is the pathological feature of Parkinson's disease (PD). Resveratrol (Res), a polyphenol derived from grapes and blueberries, has been reported to reduce oxidative stress injury and to restore mitochondrial function. In this study, we aimed to explore the underlying molecular mechanism of the beneficial effects of Res against MPP+- induced mitochondrial dysfunction and cell apoptosis in SN4741 cells. The data showed that Res significantly alleviated MPP+- induce cytotoxicity and restored MPP+- induced mitochondrial dysfunction in SN4741 cells...

Wine by-products, in particular grape pomace, can be an important source of polyphenols and dietary fibers and are increasingly being used as a starting material in the industrial production of plant food supplements, such as other matrices containing biomolecules, with antioxidant properties. The risk associated with the consumption of these products was recently analyzed through a study of potential genotoxic and carcinogenic compounds that can be found in the marketed products. In particular, occurrence data about contamination with the mycotoxin ochratoxin A were also reported...

Secondary caries at the tooth-resin interface is the primary reason for replacement of resin composite restorations. The tooth-resin interface is formed by the interlocking of resin material with hydroxyapatite crystals in enamel and collagen mesh structure in dentin. Efforts to strengthen the tooth-resin interface have identified chemical agents with dentin collagen cross-linking potential and antimicrobial activities. The purpose of the present study was to assess protective effects of bioactive primer against secondary caries development around enamel and dentin margins of class V restorations, using an in vitro bacterial caries model...

The efficacy of different combinations of under-vine and inter-row treatments for managing a soil-dwelling orthopteran pest, weta (Hemiandrus sp.), in vineyards was investigated over two seasons. This insect damages vine buds, thus reducing subsequent grape yield. The under-vine treatments comprised pea straw mulch, mussel shells, tick beans (Vicia faba Linn. var minor (Fab)), plastic sleeves on vine trunks (treated control) and control (no intervention), while inter-rows contained either the existing vegetation or tick beans...

INTRODUCTION: If adhesive restorations are carried out imme-diately, the Shear Bond Strength (SBS) to bleached enamel is reduced. The use of antioxidants can be highlighted since it seems to be a more effective alternative to reduce or remove the residual oxygen and immediate improvement in SBS. AIM: The purpose of this in-vitro study was an attempt to regain the lost bond strength, for which, the comparison of SBS of composite resin to bleached enamel was carried out using various antioxidants i...

A clinical study was conducted to assess the safety and tolerability of oral doses of proanthocyanidin-rich grape seed extract (GSE) in healthy Japanese adult volunteers. In an open-label, 4-week toxicity test, 29 subjects daily received 1,000, 1,500, or 2,500 mg GSE orally. Serum Fe levels of two subjects in the 2,500 mg GSE group decreased to 61 and 60 μg/100 mL from 205 and 182 μg/100 mL at baseline respectively, at second week of GSE consumption; these values are low but within the normal range for the Japanese population...

We recently demonstrated that California table grapes and a methanol-extractable, polyphenol-rich fraction decreased adiposity, insulin resistance, or markers of inflammation in high-fat fed mice. Malvidin and peonidin glycosides were the 2 most abundant anthocyanins in the polyphenol-rich fraction. We hypothesized that a blood borne combination of anthocyanidins malvidin and peonidin derived from intestinal β-glycosidase metabolism of these 2 anthocyanins are responsible, in part, for the beneficial health effects observed in vivo...

Social psychologists typically conceptualize intergroup processes in terms of unequal pairs of social categories, such as an advantaged majority (e.g., 'Whites') and a disadvantaged minority (e.g., 'Blacks'). We argue that this two-group paradigm may obscure the workings of intergroup power by overlooking: (1) the unique dynamics of intergroup relations involving three or more groups, and (2) the way some two-group relationships function as strategic alliances that derive meaning from their location within a wider relational context...

Grapes (Vitis spp.) produce diverse polyphenolic compounds, which are phytochemicals that contribute to human health. In this study, the polyphenolic profiles of the red-purple berries of two wild grape species native to Japan, Vitis ficifolia and V. coignetiae, and their interspecific hybrid cultivars were investigated and compared with the profiles of V. vinifera and V. × labruscana cultivars. Proanthocyanidins (PAs) were present at lower concentrations in both skins and seeds of wild grape species and their hybrid cultivars than those in V...
