L'Aborigène de Riga. Anthologie de poèmes de Janis Rokpelnis. Choix, traduction et commentaire par Alain Schorderet. Avec des encres de Catherine Bolle

Ce livre présente un choix de poèmes d’un des plus grands poètes lettons des quarante dernières années, Jānis Rokpelnis. Mêlant tradition et modernité, érudition et banalité dans ses vers, influencé par les traditions occidentale et locale, Jānis Rokpelnis a su traverser des périodes mouvementées avec une constance remarquable ; son œuvre documente aussi, mais sur un plan abstrait et jamais politique au sens premier du terme, la transformation d’un pays entre Union soviétique et indépendance.

[Smoking and digestive tract: a complex relationship. Part 2: Intestinal microblota and cigarette smoking]

The digestive tract is colonized from birth by a bacterial population called the microbiota which influences the development of the immune system. Modifications in its composition are associated with problems such as obesity or inflammatory bowel diseases. Antibiotics are known to influence the intestinal microbiota but other environmental factors such as cigarette smoking also seem to have an impact on its composition. This influence might partly explain weight gain which is observed after smoking cessation. Indeed there is a modification of the gut microbiota which becomes similar to that of obese people with a microbiotical profile which is more efficient to extract calories from ingested food. These new findings open new fields of diagnostic and therapeutic approaches through the regulation of the microbiota.
