Polyphenols derived from green tea have been reported to have a wide range of profound functions. Tea catechins, including epicatechin (EC), epigallocatechin (EGC), epicatechin-3-O-gallate (ECG) and epigallocatechin-3-O-gallate (EGCG), are considered as the major bioactive polyphenols in tea. The present study was designed to elucidate the potential antifibrogenic role of three abundant tea catechins (ECG, EGC, EGCG) in CCl4-induced fibrotic rat and its underlying molecular mechanisms. Tea catechins, especially groups of ECG, EGC and EGCG, effectively induced several beneficial alterations of liver injury markers, oxidative status and liver histology...

This study investigated the potential of ZnO-nanoparticle (NP) seed treatments for enhancing Zn nutrition in wheat ( Triticum aestivum). We tested bare, ZnO core Zn3 (PO4 )2 shell, dextran (DEX)-coated, and dextran sulfate (DEX(SO4 ))-coated ZnO NPs and ZnSO4 solution as an ionic control. We measured root and shoot Zn concentrations, lengths, biomasses, and seed germination upon termination of the assay. All ZnO NPs were more effective than ZnSO4 in increasing tissue Zn concentrations and seedling growth. Exposure to higher concentrations of ZnSO4 significantly decreased growth and germination rates relative to those of the controls and the ZnO-NP groups, whereas none of the ZnO NPs significantly affected seed germination...

Phenylurea herbicides (PHs) are frequently detected as major water contaminants in areas where there is extensive use. In this study, Diaphorobacter sp. strain LR2014-1, which initially hydrolyzes linuron to 3,4-dichloroanaline, and Achromobacter sp. strain ANB-1, which further mineralizes the produced aniline derivatives, were isolated from a linuron-mineralizing consortium despite being present at low abundance in the community. The synergistic catabolism of linuron by the consortium containing these two strains resulted in more efficient catabolism of linuron and growth of both strains...

This study aimed to investigate the inhibitory mechanism of epicatechin (EC) on the formation of acrylamide in Maillard reactions. The glucose + asparagine model is a typical chemical system used to investigate acrylamide formation. 5-Hydroxymethylfurfural (HMF) is an important carbonyl intermediate in Maillard reactions and can also react with asparagine to form acrylamide. Time courses showed that EC inhibited more HMF than acrylamide in the glucose + asparagine model heated at 180 °C. The reduction of EC on acrylamide formation in the HMF + asparagine model was about 70%, while that in the glucose + asparagine model was about 50%...

Given the importance of (-)-epigallocatechin gallate (EGCG) as an autophagy-enhancing and thereby lipid-lowering agent, optimization of its activity warrants its therapeutic potential in the treatment of hepatic diseases as well as metabolic disorders. Based on our previous observations that structural modifications provided substantial improvements in the bioactivity of EGCG, we investigated the autophagy-enhancing activity of EGCG derivatives. Among 14 EGCG derivatives, E10 with a phenylalanine attached to the D-ring of the EGCG exhibited the most promising effects in stimulating autophagy in Huh7 cells, which was supported by several lines of evidence: 1) stimulation of autophagy revealed by an increased amount of LC3B-II (4...

To investigate the effect of heat treatment on the anti-tumor activity of lactoferrin in colon cancer cells and colon tumors, the HT-29 (human intestinal epithelial tumor cell) cell line was exposed to lactoferrin and various heat treatments. The impacts on cell proliferation, invasion as well as migration was observed in vitro, and nude mice bearing HT29 tumors were administered lactoferrin and underwent various heat treatments in vivo. In the HT29 cell proliferation test using transwell and scratch analyses, lactoferrin (20 mg/mL) without or with heat treatment (50℃ and 70℃) significantly inhibited cell proliferation, migration and invasion (compared with the control, p<0...

Preplanting foliar spray of salicylic acid (SA) (0.0, 5.0, and 10.0 μg/mL) to Solanum lycopersicum (L.) altered the metabolite profile of amino acids, γ-aminobutyric acid (GABA), and SA in leaf, root, and fruits. Free amino acid pools increased; bound amino acid pools reduced. In vegetative tissues, amino acid biosyntheses linked to osmo-compatibility (Pro, Leu, Val and GABA); N (Arg, Asn, Asp, Gln, and Glu); C (Pro, Ser, and Tyr); S (Cys) assimilation; stress tolerance (Ala, Gly, Hyp, His, Lys, Met, and Thr); and central metabolism (Phe, Trp, and Tyr) enhanced for 60-120 days...

Glutathione, a tripeptide antioxidant, has recently been shown to be either utilized or synthesized by gram-positive bacteria, such as Lactic Acid Bacteria. Glutathione plays an important role in countering environmental stress, such as oxidative stress. In this study, cellular activity regarding glutathione in Lactobacillus fermentum CECT 5716 is characterized. We demonstrate that L. fermentum CECT 5716 has a better survival rate in the presence of glutathione under both oxidative and metal stress. As L. fermentum CECT 5716 does not possess the ability to synthesize glutathione under the conditions tested, it shows the ability to uptake both reduced and oxidized glutathione from the environment, regenerate reduced glutathione from oxidized glutathione, and perform secretion of glutathione to the environment...

Three varieties of honey of different dominant floral origin were found to attract social Hymenoptera, including large earth bumble bee, Bombus terrestris in a New Zealand's mountain beech forest. This study was undertaken to identify volatile organic compounds that induce the attraction of bumble bees to honeybee (Apis mellifera) honey. We have analyzed the chemical composition of the volatile organic compounds produced in three distinct varieties of honey (i.e. mānuka, honeydew and clover honey). The composition of the chemical profile of the three honey varieties differed in the quality and in the ratio of compounds in the headspace...

It remains inconclusive regarding the dose-dependent effect of egg consumption on plasma cholesterol in humans. It is unknown if egg white consumed in a normal amount can reduce plasma cholesterol. We used hamsters as a model to (i) investigate the dose-dependent effect of consuming 0 to 5 whole eggs on plasma total cholesterol (TC), and (ii) examine if egg white equivalent to 1-5 eggs possessed any reducing effect on plasma TC. In experiment 1, hamsters were divided into 6 groups (n=8 each) and fed either a control diet or five experimental diets supplemented with whole egg powders equivalent to 1 to 5 eggs/2000 kcal...
