Chronic inflammatory bowel disease is characterised by an up-regulation of the synthesis and release of a variety of pro-inflammatory mediators leading to excessive tissue injury. Flavonoids are able to inhibit enzymes and/or due to their antioxidant properties regulate the immune response. The goal of the present study was to evaluate the mechanisms of action of phenolic compounds present in g...

Food (energy) consumption rates ofMeloidogyne incognita were calculated on Vitis vinifera cv. French Colombard (highly susceptible) and cv. Thompson Seedless (moderately resistant). One-month-old grape seedlings in styrofoam cups were inoculated with 2,000 or 8,000 M. incognita second-stage juveniles (J2) and maintained at 17.5 degree days (DD - base 10 C)/day until maximum adult female growth ...

The copigmentation effect of prefermentation additions of different doses of caffeic acid was investigated during the 1997 harvest. Microfermentation with the major red grape cultivars Listán negro and Negramoll, grown in the Canary Islands, was carried out with the same protocol. Visible and UV spectra were registered periodically. HPLC chromatograms were carried out. The color enhancement of ...

Grape is one of the most popular and widely cultivated fruits in the world. Although grape skin and seeds are waste product of the winery and grape juice industry, these wastes contain large amounts of phytochemicals such as flavonoids, phenolic acids, and anthocyanidins, which play an important role as chemopreventive and anticancer agents. We evaluated efficacies of grape skin and seeds on he...

The initial concentration of anthocyanin and proanthocyanidin in wine affects the development SO 2 -resistant pigments, as well color non-color contributing polymeric fractions. However, effect extracted monomeric Pinot Noir ( Vitis vinifera L. cv.) grape anthocyanins with seed proanthocyanidins are poorly studied. In model ferments, reaction purified cv. noir extract were investigated at high ...

In grape cell cultures cv. Gamay Fréaux var. Teinturier, Ca was shown to decrease pigmentation through the inhibition of anthocyanin biosynthesis, while stimulating stilbenoids accumulation. Because methyl jasmonate (MeJA) is a well-known inducer secondary metabolism in cells, and antagonizes its stimulatory effect over several enzymes core metabolic branches, present study we hypothesized that...

Abstract Muscadinia rotundifolia, the muscadine grape, has been cultivated for centuries in southeastern United States. M. rotundifolia is resistant to many of pathogens that detrimentally affect Vitis vinifera, grape species commonly used winemaking. For this reason, a valuable genetic resource breeding. Single-molecule real-time reads were combined with optical maps reconstruct two haplotypes...

Grape canes, also named vine shoots, are well-known viticultural byproducts containing high levels of phenolic compounds, which associated with a broad range health benefits. In this work, grape canes (Vitis vinifera cv. Pinot noir) were extracted in 750 L pilot-plant reactor under the following conditions: temperature 80 °C, time 100 min, solid/liquid ratio 1:10. The comprehensive characteriza...

In this paper we describe the current status of the GRAPE-6 project to develop a special-purpose computer with a peak speed exceeding 100 T ops for the simulation of astrophysical N -body problems. One of the main targets of the GRAPE-6 project is the simulation of dense stellar systems. In this paper, therefore, we overview the basic algorithms we use for the simulation of dense stellar system...
