Oral treatment with catechin isolated from Japanese green tea significantly inhibits the growth of periodontal pathogen Porphyromonas gulae and ameliorates the gingivitis and halitosis caused by periodontal disease in cats and dogs.

It has been postulated that 90 % of cats and dogs develop periodontal disease by 1 year of age. Periodontal disease develops because of infection by multiple bacteria, including Porphyromonas gulae (P. gulae) and Porphyromonas gingivalis (P.

Genetic diversity of preserved rice seed samples from the Mikawa area, Japan, stored in the Meiji era.

Preserved rice ( L.) seeds stored for nearly a century as an emergency food stocks from the Mikawa area were investigated for their genetic diversity. Morphologically, the seeds appeared to be typical Japonica.

Identification of a gene encoding polygalacturonase expressed specifically in short styles in distylous common buckwheat (Fagopyrum esculentum).

Common buckwheat (Fagopyrum esculentum) is a heteromorphic self-incompatible (SI) species with two types of floral architecture: thrum (short style) and pin (long style). The floral morphology and intra-morph incompatibility are controlled by a single genetic locus, S. However, the molecular mechanisms underlying the heteromorphic self-incompatibility of common buckwheat remain unclear.

ZEB1 expression is associated with prognosis of intrahepatic cholangiocarcinoma.

Background/aim: Intrahepatic cholangiocarcinoma (ICC) is one of the most aggressive malignant tumours, so the identification of molecular targets for ICC is an important issue. Zinc finger E-box binding homeobox 1 (ZEB1) is a key inducer of epithelial-mesenchymal transition (EMT). The aim of the present study was to clarify the clinical significance of ZEB1 in ICC and the associations between ZEB1 expression and EMT-related proteins.
