Background: Allergens are mostly composed of glycoprotein structures. It is believed that glycan-specific antibodies may lead to false-positive reactions in immunoassays. In this study we investigated the glycosylation state of grape allergens as well as the presence of antibodies to cross-reactive carbohydrate determinants (anti-CCDs) in sera from grape-sensitive individuals. Methods: Grape...

In this study, the freeze-dried powders from whole grapes, pomace and juice of Campbell Early (Vitis labruscana Bailey) were prepared to determine the amount of total flavonoids, vitamins A, C, and E, and dietary fiber. Effects of whole grape, pomace, or juice intakes on their antioxidative capacity and DNA damage were investigated in Sprague-Dawley male rats. A total of 120 rats at 13 mo old a...

Tekeli, A., H. RuSTu kuTlu and l. Celik, 2014. Dietary inclusion of grape seed oil in functional broiler meat production. Bulg. J. Agric. Sci., 20: 924-932 The purpose of this study is to explore the effects of grape seed oil on growth performance, some blood parameters and fatty acid composition in broiler meat. in order to formulate isocaloric ratios, the corresponding amounts of soy oil were...

In 2001, $13 million were invested in various grape and wine R&D programs via the Australian Grape and Wine Research and Development Corporation. Half of the funds come from compulsory levies from grape-growers and winemakers, and the other half from Commonwealth government matching grants. These funds are then allocated to research projects across broad areas such as grape production R&D, wine...

We herein evaluate intraspecific genetic diversity of fermentative vineyard-associated S. cerevisiae strains and evaluate relationships between grape varieties and geographical location on populational structures. From the musts obtained from 288 grape samples, collected from two wine regions (16 vineyards, nine grape varieties), 94 spontaneous fermentations were concluded and 2820 yeast isolat...

Proanthocyanidins, compounds highly concentrated in dietary fruits, such as cranberries and grapes, demonstrate significant cancer prevention potential against many types of cancer. The objective of this study was to evaluate cranberry and grape seed extracts to quantitate and compare their anti-proliferative effects on the most common type of oral cancer, oral squamous cell carcinoma. Using tw...

Prostate cancer (PCa) is one of the most common malignancies in men with approximately 0.9 million newly diagnosed cases and 0.26 million deaths in 2008 worldwide (Jemal et al., 2011). Until now, the exact carcinogenic mechanism of prostate cancer has remained unclear (Mahmoud et al., 2014). It is widely accepted that carcinogenesis of prostate cancer is affected by genetic susceptibility and e...

Low molecular weight phenols of Tannat red wines produced by Traditional Maceration (TM), Prefermentative Cold Maceration (PCM), Maceration Enzyme (ENZ) and grape-Seed Tannins additions (ST), were performed and discussed. Alternatives to TM increased wine phenolic contents but unequally, ST increased mainly smaller flavans-3-ol, PCM anthocyanins and ENZ proanthocyanidins (up to 2250 mg/L). Howe...
