BACKGROUND Helicobacter pylori eradication rates with standard triple therapy in many countries are clinically unacceptable. Fluoroquinolone resistance is increasing and jeopardizing second-line regimens. There is a growing need for an effective strategy in patients who failed previous therapies. METHODS This is a single-center, non-randomized clinical study conducted in the central region of...

Recently, we identified an alginate-assimilating gene cluster in the genome of Flavobacterium sp. strain UMI-01, a member of Bacteroidetes. Alginate lyase genes and a 4-deoxy-l-erythro-5-hexoseulose uronic acid (DEH) reductase gene in the cluster have already been characterized; however, 2-keto-3-deoxy-d-gluconate (KDG) kinase and 2-keto-3-deoxy-6-phosphogluconate (KDPG) aldolase genes, i.e., f...

Mieko Yamada Department of Applied Mathematics Konan University Okamoto, Higashinada-ku Kobe 658, Japan Partially balanced incomplete block designs, PBIBDs, are designs for which the property of balance of BIBD is relaxed. They are based on an association scheme. We introduce the concept of generalized relative difference sets, generalizing the concept of relative difference sets introduced by ...

Background and Objectives: To evaluate the utility of the constructs functioning and disability (F&D) and dependency for case-mix and subtyping of patients with schizophrenia by psychosocial, clinical, use of services and attention received from informal carers. Methods: A randomly selected total of 205 people with schizophrenia, and their careers were evaluated through PANSS, DAS-sv, Objective...

We report on the self-assembly behaviour of two homologue series of rod-coil block copolymers in which, the rod, a pi -conjugated polymer, is maintained fixed in size and chemical structure, while the coil is allowed to vary both in molecular weight and chemical nature. This allows maintaining constant the liquid crystalline interactions, expressed by Maier-Saupe interactions, omega , while var...
