STATEMENT OF PROBLEM Hard denture acrylic resins must maintain color stability to remain esthetic. PURPOSE The purpose of this in vitro study was to measure the color stability of denture resins subjected to staining agents and cleaned with denture cleansers MATERIAL AND METHODS Forty-five disks (10-mm diameter, 2-mm thick) fabricated from 3 denture resins (light polymerized Eclipse; heat p...

Thaumatin-like proteins (TLPs) and chitinases are the main constituents of so-called protein hazes which can form in finished white wine and which is a great concern of winemakers. These soluble pathogenesis-related (PR) proteins are extracted from grape berries. However, their distribution in different grape tissues is not well documented. In this study, proteins were first separately extracte...

In this study Illumina MiSeq was performed to investigate microbial diversity in soil, leaves, grape, grape juice and wine. A total of 1,043,102 fungal Internal Transcribed Spacer (ITS) reads and 2,422,188 high quality bacterial 16S rDNA sequences were used for taxonomic classification, revealed five fungal and eight bacterial phyla. At the genus level, the dominant fungi were Ascomycota, Sorda...

We overview the GRAPE (GRAvity piPE) project. The goal of the GRAPE project is to accelerate the astrophysical N -body simulations. Since almost all computing time is spent for the evaluation of the gravitational force between particles, we can greatly accelerate many N -body simulations by developing a specialized hardware for the force calculation. In 1989, the first such hardware, GRAPE-1, w...

The aim of this review is to discuss the accumulating evidence that suggests that grape extracts and purified grape polyphenols possess a diverse array of biological actions and may be beneficial in the prevention of some inflammatory-mediated diseases including cardiovascular disease. The active components from grape extracts, which include the grape seed, grape skin, and grape juice, that hav...

After a 1-year hiatus, it’s time once again for the (almost) annual update and review on controlling the fungal diseases that grape growers must regularly contend with in our eastern climate. As always, I’d like to acknowledge the outstanding team of grape pathologists here in Geneva, which includes bacteriologists (Tom Burr’s program) and virologists (Marc Fuchs’s program) in addition to those...

The aim of this study was to analyse the influence of low-temperature wine fermentation on nitrogen consumption and nitrogen regulation. Synthetic grape must was fermented at 25 and 13 C. Lowtemperature decreased both the fermentation and the growth rates. Yeast cells growing at low-temperature consumed less nitrogen than at 25 C. Specifically, cells at 13 C consumed less ammonium and glutamine...

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...

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...
