Helicobacter pylori GroEL Seropositivity Is Associated with an Increased Risk of Opisthorchis viverrini-Associated Hepatobiliary Abnormalities and Cholangiocarcinoma.

Despite the synergistic effect of Opisthorchis viverrini and Helicobacter pylori co-infection on pathogenesis of severe hepatobiliary abnormalities (HBA) including advanced periductal fibrosis and replace with cholangiocarcinoma (CCA) have been established, the immune response to H. pylori in O. viverrini infected population has never been explored.

Identification, recombinant protein production, and functional analysis of a M60-like metallopeptidase, secreted by the liver fluke Opisthorchis viverrini.

The carcinogenic liver fluke Opisthorchis viverrini (O. viverrini) is endemic in Thailand and neighboring countries including Laos PDR, Vietnam and Cambodia. Infections with O.

UV damage endonuclease employs a novel dual-dinucleotide flipping mechanism to recognize different DNA lesions.

Repairing damaged DNA is essential for an organism's survival. UV damage endonuclease (UVDE) is a DNA-repair enzyme that can recognize and incise different types of damaged DNA. We present the structure of Sulfolobus acidocaldarius UVDE on its own and in a pre-catalytic complex with UV-damaged DNA containing a 6-4 photoproduct showing a novel 'dual dinucleotide flip' mechanism for recognition of damaged dipyrimidines: the two purines opposite to the damaged pyrimidine bases are flipped into a dipurine-specific pocket, while the damaged bases are also flipped into another cleft.
