The effects of resistant starches of beans on serum cholesterol and hepatic low density lipoprotein (LDL) receptor mRNA in rats were investigated. Rats were fed a cholesterol-free diet with 150 g/kg corn starch (CS), 150g/kg adzuki (Vigna angularis) starch (AS), 150 g/kg kintoki (Phaseolus vulgaris, variety) starch (KS), or 150 g/kg tebou (P. vulgaris,(More)
Five sterylglycosides (acylmono-, mono-, di tri- and tetraglycosylsterol) and a saponin were isolated from Adzuki beans and characterized. In the glycosylsterols, the principal component sterols were sitosterol and stigmasterol; the major sugar component was glucose. The glucose units were shown to be linked by β1,6-bonds. The three oligoglycosylsterols(More)
Our open-label pilot study showed that supplementation with docosahexaenoic acid (DHA) increased serum brain-derived neurotrophic factor (BDNF) levels and that there might be an association between changes in serum BDNF levels and reduced psychological distress. Animal research has indicated that a DHA-enriched diet increases BDNF in the brain. In this(More)
We examined the effects of the resistant starches of adzuki (Vigna angularis), kintoki (Phaseolus vulgaris, variety), and tebou (P. vulgaris, variety) beans on the lipid metabolism in rats. Rats were fed a cholesterol-free diet with 25 g of cornstarch (CS)/100 g diet, 25 g of adzuki starch (AS)/100 g diet, 25 g of kintoki starch (KS)/100 g diet, or 25 g of(More)
Feeding rats beans with resistant starch reduces their serum cholesterol concentration; however, the mechanism by which this occurs is not fully understood. We examined the effects of enzyme-resistant fractions of adzuki (Vigna angularis) and tebou (Phaseolus vulgaris, var.) beans on serum cholesterol and hepatic mRNA in rats. Rats were fed a(More)
Multiple classes of acyl-CoA binding proteins are encoded by plant genomes, including a plant-unique class of predicted integral membraneproteins. Transcript analysis revealed that both of the integral membrane-acyl-CoA binding proteins of Arabidopsis thaliana, ACBP1 and ACBP2, are expressed in all organs. Expression of ACBP2 was highest in developing roots(More)
