Polybrominated diphenyl ethers (PBDEs) are a new class of global, persistent, and toxic contaminants, which need proper remediation technologies. PBDE degradation in the environment is not well understood. In this study, PBDEs with zerovalent iron was investigated six BDEs, substituted one to 10 bromines. Within 40 days 92% BDE congener 209 transformed into lower bromo congeners. During initial reaction period (<5 days), hexa- heptabromo BDEs were most abundant products, but tetra-...
5-Fluorouracil (5-FU) is a widely used anticancer drug for the treatment of colorectal cancer (CRC). However, resistance to 5-FU often prevents success chemotherapy. Nuclear factor-erythroid 2-related factor 2 (Nrf2) transcriptional regulator and possible target overcome resistance. The present study examined epigenetic changes associated with Nrf2 induction in human CRC cell line (SNUC5) resistant (SNUC5/5-FUR). expression, nuclear translocation, binding promoter were higher SNUC5/5-FUR...
The ferulic and gallic acid related compounds from natural origin were studied against xanthine oxidase cyclooxygenase-2 along with their anti-inflammatory activity. acid, caffeic p-coumaric revealed promising activity (30–40% TNF-α 60–75% IL-6 inhibitory at 10 μM). Bioavailability of checked by in vitro cytotoxicity using CCK-8 cell lines confirmed to be nontoxic, but found toxic higher concentration (50 Gallic, ferulic, was demonstrated potential dual inhibition toward as calculated IC50:...
Nineteen bacterial strains were isolated from petroleum-contaminated soil in Hilo, HI, and characterized by two different spray-plated methods, turbidity test liquid medium, 16S rRNA gene sequence analysis. Analysis of the showed 13 polycyclic aromatic hydrocarbons (PAHs) a range 0.6 to 30 mg/kg dry weight each 12 PAH metabolites. Five distinct (C3, C4, P1-1, JS14, JS19b1) selected preliminary plating tests further tested for degradation through single assay. Strains C3, P1-1 degraded...
