\n\nDesign\n\nPost hoc analysis of isoflavonoid exposure (mean 2.7years) during the randomized,
placebo-controlled, double-blind Women’s Isoflavone Soy Health trial.\n\nSetting\n\nGeneral community.\n\nParticipants\n\nHealthy postmenopausal women (N= 350).\n\nIntervention\n\nTwenty-five grams of isoflavone-rich soy protein (91mg of aglycone weight isoflavones: 52mg genistein, 36mg daidzein, 3mg glycitein) buy Blebbistatin or milk protein-matched placebo provided daily.\n\nMeasurements\n\nOvernight urine excretion, fasting plasma levels of isoflavonoids, and cognitive function measured at baseline and endpoint.\n\nResults\n\nThree hundred women (age: mean 61, range 45-92) completed both cognitive assessments and did not use hormone replacement therapy during the trial. Mean on-trial change from baseline in urine excretion of isoflavonoids was not significantly associated with change in a composite score of global cognition (P=.39). Secondary analyses indicated that change in urine excretion of isoflavonoids was inversely associated with change in a factor score representing general intelligence (P=.02) but not with factor scores representing verbal or visual episodic memory. AR-13324 datasheet Mean differences
in this general intelligence factor score between women in the lowest and highest quartiles of isoflavonoid change were equivalent to an approximate 4.4-year age-associated decline. Analyses based on plasma isoflavonoid levels yielded similar but attenuated results.\n\nConclusion\n\nIn healthy postmenopausal women, long-term changes in isoflavonoids are not associated with global cognition, A-769662 supporting clinical trial results, although greater isoflavonoid exposure from dietary supplements is associated with decrements in general intelligence but not memory; this finding requires confirmation in future studies.”
“Crude extracts from Inula aucherana, Fumaria officinalis, Crocus sativus, Vicum album, Tribulus terestris, Polygonatum multiflorum, Alkanna tinctoria and Taraxacum officinale were screened for their in vitro antioxidant and antimicrobial
properties. Total phenolic content of extracts from these plants were also determined. beta-carotene bleaching assay and Folin-Ciocalteu reagent were used to determine total antioxidant activity and total phenols of plant extracts. Antimicrobial activity was determined by using disk diffusion assay. Antioxidant activity and total phenolic content varied among plants used and Viscum album and Crocus sativus had the highest antioxidant (82.23%) and total phenolic content (42.29 mgGAE/g DW), respectively. The methanol extracts from Vicum album and Alkanna tinctoria showed antimicrobial activity against 9 out of 32 microorganisms, however extract from Inula aucherana showed antimicrobial activity against 15 out of 32 microorganisms. The results provided evidence that the studied plant might indeed be potential sources of natural antioxidant and antimicrobial agents.
