Anthocyanins are antioxidants and are among the natural products synthesized via the flavonoid biosynthesis pathway. Anthocyanins have been recommended for dietary intake in the prevention of cardiovascular diseases, cancer, and age-related conditions such as Alzheimer's disease or dementia. With an increasingly aging population in many parts of the world, strategies for the commercial producti...

Dietary resveratrol (3,4',5-trihydroxystilbene) has been implicated in the health benefits associated with grapes and red wine, more specifically with potential benefits for metabolic syndrome, energy use, and increased endurance. Levels of trans-resveratrol and its glucoside, trans-piceid, were determined in 19 top selling commercially available cocoa-containing and chocolate products from the...

BACKGROUND Clinical evidence supports the relationship between carbonyl stress and type II diabetes and its related pathologies. Methylglyoxal (MGO) is the major dicarbonyl compound involved in carbonyl stress. Efforts are therefore being made to find dietary compounds from natural sources that could exert an MGO trapping response. RESULTS The in vitro MGO trapping capacity of six red and sev...

In light of their environmental and economic interests, food byproducts have been increasingly exploited and valorized for their richness in dietary fibers and antioxidants. Phenolic compounds are antioxidant bioactive molecules highly present in grape byproducts. Herein, the accelerated solvent extraction (ASE) of phenolic compounds from wet and dried grape pomace, at 45 °C, was conducted and ...

Seeds of lettuce (Lactuca sativa L. cv. Grand Rapids) were imbibed and given either short irradiation with red or far red light prior to drying or dried under continuous red or far red light. Seeds treated with either short or continuous red germinate in darkness, whereas seeds treated with either short or continuous far red require a short exposure to red light, after a period of imbibition, t...

During the dormant period a series of five samples of the buds and of the preceding year's growth was taken from a number of dominant and codominant yellow poplar trees. The samples were dried in an oven at 650 C., and were then ground in a ball mill until the material would pass through a 100-mesh sieve. Duplicate samples of from 25 to 50 grams were taken from this large sample, covered with 8...

embryogenic callus initiation from anther and whole flower explants in four grapevine cultivars including flame seedless, shahroodi, perlette and red sultanina cultured on piv and harst nutrient media was studied. results showed that whole flower explants of ‘flame seedless’ cultured on piv medium had the most potential for callus production. later callus were transferred onto ges1ca medium for...

objective: parkinson's disease (pd) is one of the most common neurodegenerative disorders which is characterized by tremor, rigidity, bradykinesia and postural disturbances. studies indicate that grape juice and exercise may have beneficial effects on neurodegenerative disorders. therefore, in the present study, we evaluated the effects of red grape juice (gj) together with treadmill runni...
