Recent experimental data point to an interaction of dietary flavonol monoglucosides with the intestinal Na-dependent glucose transporter 1 (SGLT1). To investigate this interaction in more detail, we performed experiments with SGLT1-containing brush-border-membrane vesicles (BBMV) from pig jejunum. The flavonol quercetin-3-O-glucoside (Q3G) concentration-dependently inhibited Na-dependent uptake...
BACKGROUND Quercetin, nature's most common flavonoid, possesses anticarcinogenic properties against various forms of cancer. The aim of this study was to investigate the effect of quercetin on breast cancer stem cells in the MDA-MB-231 cell line, and to elucidate the possible mechanisms for those effects. MATERIAL AND METHODS We evaluated breast cancer stem cell proliferation, clone generation,...
as far as bandura’s (1977) conceptualization of the sense of self-efficacy is concerned, it is argued to be context- and even task-specific, compared to other concepts like self-esteem (brown, 2000); therefore, upon the previous research studies, related theories and definitions, and the ideas and views obtained from the interviews conducted with the scholars, the current research study aimed a...
Rhizopus azygosporus Yuan et Jong (ATCC 48108), a starter culture for fermented soybean tempeh, produces β-glucosidases that cleave flavonoid glycosides into aglycones during fermentation. However, recent data suggest that fermentation of a flavonoid glycoside-rich extract with this strain did not result in the production of aglycones. Thus, in this paper, flavonoid metabolism of this strain wa...
The seeds of Indigofera heterantha yielded a flavonoid characterized as quercetin 3-O-α-L-rhamnoside along with known 3,5,7-trihydroxy-6,4 ́-dimethoxyflavone and 3,5,4 ́-trihydroxy-6,7-dimethoxyflavone. The isolated compounds were characterized by using modern spectroscopic techniques such as UV, IR, NMR and mass.
This study examined the effects of quercetin on spontaneously contracting portal veins isolated from healthy young adult male and female Wistar rats (250-300 g). Quercetin (10(-7)-10(-4) M) always produced significant biphasic effects, comprising an initial brief stimulant effect (rise in basal tone), followed by a sustained, longer-lasting secondary relaxant (inhibitory) effect on the venous t...
Lesion of the gastric mucosa is the most prevalent side effect of aspirin. Flavonoids with actions such as antioxidant, free radical scavenger and lipid peroxidant inhibitor can prevent mucosal lesion caused by aspirin. In this research effect of quercetin, as the most abundant flavonoid in human diet, was investigated on preventing ulcerogenic effect of aspirin or Acetyl&nb...
background and aims: tribulus terrestris fruit, leaf, and root have medical effects in the treatment of cancer, viral infections and prevention of cardiovascular diseases. the present study was aimed to evaluate the quercetin flavonoid levels from different parts of the tribulus terrestris collected from different regions of khuzestan in 2014. methods: in this experimental study, four parts of ...
