The polysaccharide and flavonoid concentrations of two-, three-, four-year-old Aloe vera were determined, their antioxidant activities evaluated compared to BHT α-tocopherol by the DPPH radical scavenging method linoleic acid system at 100 μg soluble solids per mL ethanol. results showed that three-year-old contained significantly higher levels polysaccharides flavonoids than two- vera, no significant differences in found between three- vera. All aloe extracts activity. activity reference...

This research was to determine the effect of foliar application selenium on increasing antioxidant activity tea harvested during early spring producing season using a α,α-diphenyl-β-picrylhydrazyl (DPPH) radical scavenging method and linoleic acid system. The results showed that ability extracts followed this order first 60 min: selenium-enriched obtained by fertilization with selenate > BHT obatined selenite α-tocopherol regular tea. Se-enriched exhibited highest inhibition percentage...

Abstract Atomic fluorescence spectrophotometry was used to determine the selenium (Se) concentration in 30 rice products of different species from Southern China. The Se level ranged 0.015 0.046 µg g −1 . Considering average daily individual consumption China, dietary intake supplied by this source is only 6–18 day for an adult. This low mainly responsible total inhabitants Foliar spraying Se‐enriched fertiliser or sodium selenite with 14–18 ha heading stage growth increased content...

Selenium fertilizer was foliar applied to determine the effects of antioxidant activity selenium-enriched rice assessed by α,α-diphenyl-β-picylhydrazyl (DPPH) radical scavenging and ferric thiocyanate (FTC) method. Results showed that selenium concentration in significantly enhanced dose dependently. Aqueous or ethanolic extracts displayed higher against lipid peroxidation. The activities aqueous were than those increased with increasing rice. DPPH assay kinetic behaviors complex slow, while...

Both selenium and green tea have been shown to potential antitumor effects. Here we investigated the anticarcinogenic effect of selenium-enriched extract (Se-TE) in a Kunming mice model transplanted with human hepatoma cells HepG2. Mice were assigned 8 groups consisting 10 each after tumor cell inoculation. The control group received only water, whereas remaining regular (RT), Se-TE which was produced by fertilization selenite on leaves, selenite, RT + selenite. After fed intragastrically...

Abstract Recent successes in targeting KRASG12C have provided both insight and inspiration for alternative KRAS mutants. Among mutations, G12D is the most frequent driver mutated isoform found approximately 34% of patients with pancreatic ductal adenocarcinoma (PDAC), 12% colorectal cancer (CRC), 4% lung adenocarcinoma, a subset other solid tumors. We developed LT-010366 as first-in-class orally bioavailable degrader high potency selectivity. In vitro degradation assays, demonstrated...

Abstract This study was aimed at determining the effects of selenium on contents vitamin C, amino acid, total water‐soluble solids and tea polyphenol, whether antioxidant activity selenium‐enriched green is enhanced compared with regular by linoleic acid oxidation lard method. The selenium, C polyphenol in teas were greatly increased foliar application fertilizer. No significant differences observed between treated sodium selenite that without selenium. exhibited significantly higher than...

Lead (Pb) is a highly toxic and persistent substance that easily accumulates in living organisms, eliciting cellular toxicity oxidative stress. Some selenium-containing proteins peptides prepared from plant extracts are beneficial for protecting the body's health resisting external disturbances. In present study, peptide species were selenium-enriched Pleurotus eryngii protein hydrolysates to evaluate benefits of on Pb-induced stress NCTC1469 hepatocytes.Trypsin was selected as primary...

Previously, the antioxidant activity of Se-enriched green tea extracts has been studied in vitro. In present study, an vivo micronuclei test was employed to assess antimutagenic effect microsized powder (MSTP) mice bone marrow. Pretreatments MSTP, micrometer-sized regular (MRTP), selenite, and MRTP + selenite were given by gavage for 29 consecutive days prior cyclophoshamide (CP) treatment. Certain key enzymes also investigated elucidate mechanism effect. Results indicated that MSTP or alone...
