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...
OBJECTIVE The aim of this study was to evaluate the effect of organic grape juice intake on biochemical variables and microcirculatory parameters in triathlon athletes. INTRODUCTION The physiological stress that is imposed by a strenuous sport, such as a triathlon, together with an insufficient amount of antioxidants in the diet may cause oxidative imbalance and endothelial dysfunction. MET...
DNA damages and antioxidant status was assessed after 8 weeks of purple grape juice supplementation in male smokers depending on the glutathione S-transferase polymorphisms. Ninety-five smokers consumed 480 ml of purple grape juice for 8 weeks. The blood samples were collected before and after supplementation to measure lymphocyte DNA damages, plasma antioxidants, conjugated diene, and the eryt...
OBJECTIVE To evaluate the hardness (KHN), color stability (DE), and superficial micromorphology of two categories of composites after immersion in either distilled water or grape juice for up to 45 days. MATERIAL AND METHODS Cylindrical specimens (6 mm diameter x 2 mm thick) were obtained according to the factors: composite [Opallis (FGM) and Filtek Z350XT (3M ESPE)]; immersion solution (dist...
The phenolic composition including hydroxybenzoic acids, hydroxycinnamic acids and flavan-3-ols was identified and quantified in all studied samples by using a reversed-phase high-performance liquid chromatography (HPLC) system coupled with diode array detection. Gallic, protocatechuic, p-coumaric and vanillic acids were the major phenolic substances in grape juice, whereas caffeic acid was the...
Background and Objectives: Fatigue and sleep disturbance are side effects of radiation therapy. Grape juice is a traditional product rich in antioxidants and polyphenols that have been shown to include positive effects on improving fatigue and sleep disorders. The aim of this study was to assess effects of grape juice consumption on fatigue and sleep quality in women with breast cancer undergoi...
The Escherichia coli beta-glucuronidase gene has been used as a marker gene to monitor a killer Saccharomyces cerevisiae strain in mixed-culture ferments. The marked killer strain was cured of its M-dsRNA genome to enable direct assessment of the efficiency of killer toxin under fermentation conditions. Killer activity was clearly evident in fermenting Rhine Riesling grape juice of pH 3.1 at 18...
This study investigated the effects of ethyl maltol and carbonation on cold-pressed Venus (new Arkansas seedless grape release, 60% Vitis vinifera L. x 40% Vitis labrusca L.) and Concord (Vitis labrusca L.) grape juices and their grape-apple blends. Sensory analysis indicated Venus juice rated higher than Concord in flavor and aroma after two months of storage at 37°C. Sensory and laboratory an...
paratus. In activity 2, students can use the equipment used by hobby winemakers – a vinometer – to measure the alcohol content of the must and wine. 3. A well balanced wine needs a certain amount of fruit acid; the total acid content is a very important measure, because it directly affects the flavour. In activity 3, the acid content is determined by pH titration. Four further activitiesw2 can ...
The aim of this study was to monitor the mycobiota of wine grapes, occurrence of ochratoxigenic microfungi in wine grapes and occurrence of ochratoxin A and Alternaria mycotoxins in fresh grape juice, must and wine from domestic crops in the year 2004. Thirteen samples of wine grapes (white /nine samples/ and red /four samples/) were collected during harvesting in the Znojmo wine region, SE Mor...
