BACKGROUND In persons without clinical symptom it is difficult to assess an impact of probiotics regarding its effect on health. We evaluated the functional efficacy of the probiotic Lactobacillus fermentum ME-3 in healthy volunteers by measuring the influence of two different formulations on intestinal lactoflora, fecal recovery of the probiotic strain and oxidative stress markers of blood and...

Interest in functional foods is increasing. The aim of the present study was to investigate breads supplemented with functional components. One was bread supplemented with inulin, linseed and soya fibre (prebiotic bread). The other was a prebiotic antioxidant bread (pre-aox-bread), which additionally contained green tea powder, herbs and tomato paste. The effects of these two breads on immunolo...

Heat treatment of persimmon peel (PP) increased the antioxidative activity of the 70% ethanolic extract (EE) and water extract (WE) from PP. EE and WE both prevented H2O2-induced DNA damage to human peripheral lymphocytes. The antioxidative and antigenotoxic activities of the PP extracts were significantly affected by heating.

Microfolicoumarin (1), a prenylcoumarin from Cedrelopsis microfoliata, was synthesized from 2,4,5-trimethoxybenzaldehyde in five steps. 1 did not show significant antioxidative activity, but the key intermediates, esculetin (3) and 5-prenylesculetin (6), exhibited strong antioxidative activity in both the superoxide-radical and 1,1-diphenyl-2-picrylhydrazyl radical-scavenging models.

Euphorbia milii Des Moul is a deciduous bush indigenous to Madagascar. The present study aims investigate the presence of phytochemical, in-vitro antioxidant and antimicrobial potency, in-silico computational analysis ethanolic aqueous preparations E. leaves flowers. extracts were tested for activity by DPPH, H2O2, TAC, FRAP assay. In addition, potentials assayed agar well diffusion technique a...

Objective Evaluation of in vitro antioxidant activities of grape seed (Vitis vinifera) extract GSE, blackseed (Nigella sativa) extract NSE and curcumin CUR. Methods In vitro antioxidative potential of GSE, NSE and CUR was evaluated through determination of total soluble phenolic content and reducing power. Also, the antioxidant activity was measured using linoleic acid peroxidation assay, phosp...

Here we report the draft genome sequence of Pseudoalteromonas strain A2, isolated from Arctic seawater in the pack-ice zone, which has high antioxidative activity against H2O2. The genomics information of this strain will facilitate the study of antioxidative mechanisms, cold adaptation properties, and evolution of this genus.

Many insects in temperate regions overwinter in diapause, during which they are cold hardy. In these insects, one of the metabolic adaptations to the unfavorable environmental conditions is the synthesis of cryoprotectants/anhydroprotectants. The aim of this study was to investigate the connection between the antioxidative system and synthesis of cryoprotectants (mainly glycerol) in diapausing ...

Hepatic arterial infusion chemotherapy (HAI) using an implanted port system is the standard regimen for primary and metastatic liver cancers (MLCs). However, there have been few studies concerning HAI-induced oxidative stress and damage to the liver or other organs. The aim of the present study was to investigate the ability of green tea polyphenols (GTPs) to reduce the oxidative stress or incr...

BACKGROUND GCSB-5, an herbal drug composition with an anti-inflammatory effect, is prepared by boiling, which is the most common herbal extraction method in traditional Korean medicine. Several parameters are involved in the process, i.e., extractant type, herb-to-extractant ratio, extraction temperature and pressure, and total boiling time. OBJECTIVES The aim of this study was to examine the...
