Basement membrane remodelling regulates mouse embryogenesis.

Tissue sculpting during development has been attributed mainly to cellular events through processes such as convergent extension or apical constriction. However, recent work has revealed roles for basement membrane remodelling in global tissue morphogenesis. Upon implantation, the epiblast and extraembryonic ectoderm of the mouse embryo become enveloped by a basement membrane.

Acid-inhibitory effects of omeprazole and lansoprazole in Helicobacter pylori-negative healthy subjects.

Background: Omeprazole 20 mg once daily (o.d.) and lansoprazole 30 mg o.

Five-year cimetidine maintenance trial for peptic ulcer disease. A clinical and endocrinologic approach.

A multicentre maintenance trial was conducted in 63 peptic ulcer patients to investigate the efficacy and safety of continuous cimetidine maintenance therapy for up to 5 years. In Amsterdam the male patients were investigated yearly for possible endocrinologic changes and to monitor gastric acid secretory capacity. Patients with healed ulcers entered maintenance treatment with a 400-mg bedtime dose of cimetidine.

Alpha-1-antitrypsin phenotypes and serum concentrations in duodenal ulcer patients in The Netherlands.

Hereditary alpha 1-antitrypsin (alpha 1-AT) deficiency has been suggested to be associated with peptic ulcer disease. Since the serum concentration of the enzyme is the result of both hereditary and nonhereditary factors, we have studied not only the serum levels but also the alpha 1-AT electrophoretic variants in 177 Dutch patients with duodenal ulcer disease and compared with 357 healthy blood donors. No relation was found between any of the alpha 1-antitrypsin phenotypes and duodenal ulcer disease.

Sucralfate versus cimetidine in reflux esophagitis. A single-blind multicenter study.

A single-blind randomized multicenter study was performed in 42 patients with endoscopically documented reflux esophagitis. Patients were randomly given 400 mg cimetidine q.i.
