Age-related macular degeneration (AMD) is one of the principal causes of blindness. This study investigated the association between diet and the prevalence of AMD in elderly Korean women.
Study subjects were women aged ⩾65 years (n=1008) from the Korea National Health and Nutrition Examination
Enzymatic O-methylation of plant secondary metabolites is an important mechanism for the inactivation of reactive hydroxyl groups and for the modification of their solubility. A cDNA clone (pFOMT3') encoding the gene for the 3'/5'-O-methylation of partially methylated flavonols was isolated from
Considerable evidence shows that chronic hyperglycemia can cause pancreatic beta-cell dysfunction, which contributes to progressive deterioration of glucose homeostasis and overt diabetes. In the present study, we found that kaempferol, a flavonol compound present in various Chinese medicinal herbs,
Flavonols are important co-pigments in flower colour and are also essential for pollen tube growth. In petunia, flavonol synthesis is controlled by the Fl locus. Flavonol synthase (FLS) belongs to the 2-oxoglutarate-dependent dioxygenase family. Dioxygenase gene fragments were amplified by PCR on
UNASSIGNED
The majority of research performed to date has examined the effects of commonly known antioxidants such as vitamins C, E, and A and carotenoids on age-related macular degeneration (AMD) risk and progression. To date, there is limited research on promising phytochemicals with antioxidant
TAZ1 (TAPETUM DEVELOPMENT ZINC FINGER PROTEIN1; renamed from PEThy; ZPT3-2) cDNA was first isolated as an anther-specific cDNA from petunia. Here, we report a functional characterization that includes analysis of spatial and temporal expression profiles and examination of anther phenotypes in
Ageing is a progressive deterioration in functional and structural well-being of the body, accompanied with age-associated neurological disorders such as Parkinson's disease (PD), Alzheimer's disease and Huntington's disease. PD is marked with motor function decline, progressive neurodegeneration
3-Deoxyanthocyanins are rare anthocyanin pigments produced by some mosses, ferns, and higher plants. The enzymes and genes responsible for biosynthesis of 3-deoxyanthocyanins have not been well characterized. We identified a novel gene encoding UDP-glucose:3-deoxyanthocyanidin
The orchids GL and YL are two cultivars of Cymbidium longibracteatum. YL displays an obviously yellowing rhizome and yellow leaves, while GL ('Longchangsu') shows dark green leaves and greenish rhizome. But the molecular mechanism for the differences between the two cultivars is poorly understood.
BACKGROUND
Flavonol glucosides constitute the second group of secondary metabolites that accumulate in Crocus sativus stigmas. To date there are no reports of functionally characterized flavonoid glucosyltransferases in C. sativus, despite the importance of these compounds as antioxidant agents.
BACKGROUND
The aim of the present work was to evaluate the phytochemical profile and the antioxidant activity of strawberry fruit (cv. Camarosa) upon postharvest ripening at room temperature (20 °C) and to correlate them with qualitative attributes.
RESULTS
'Camarosa' fruit retained an appreciable
Retinal tissue is exposed to oxidative stress caused by visible light. Light-damaged rat used in age-related macular degeneration (AMD) studies clarified that antioxidants decrease retinal light damage. Albino rats were exposed to 5000 Lux light for 12 h with oral administration of the polyphenolic
For a better understanding of germination after seed storage, metabolite profiling was conducted using hybrid triple quadrupole time-of-flight (QTOF) mass spectrometry. After moisture content (MC) equilibration, seeds of "WAS170" (short-lived) and "IR65483" (long-lived) were stored at 10.9% MC and
Ginkgo biloba has been used in traditional Chinese medicine for about 5000 years. A standardized preparation, EGb 761 has been recently prepared. The pharmacologically active constituents, flavonol glycosides and the terpene lactones are standardized. The terpene lactones comprise of ginkgolides A,
Oxidative damage is an established outcome of chronic stress. Thus, the present study was designed to investigate the modulatory role of ethanolic extract of Evolvulus alsinoides (EA) in terms of oxidative alterations at peripheral and central level in rats subjected to chronic unpredictable stress
