Yoshio Yamaoka spends much of his time researching Helicobacter pylori, CagA, Gastritis, Immunology and Microbiology. His work carried out in the field of Helicobacter pylori brings together such families of science as Cancer, Gastric mucosa, Genotype and Virulence. His research integrates issues of Gastroenterology and Incidence in his study of Cancer.
Yoshio Yamaoka focuses mostly in the field of Gastritis, narrowing it down to topics relating to Intestinal metaplasia and, in certain cases, Odds ratio. His Immunology study combines topics from a wide range of disciplines, such as Epidemiology, Disease and Antrum. His Microbiology research includes themes of Helicobacter, Proinflammatory cytokine and Gene knockout.
Yoshio Yamaoka mostly deals with Helicobacter pylori, Internal medicine, Gastroenterology, CagA and Immunology. His Helicobacter pylori research includes themes of Genotype, Cancer, Microbiology and Virulence. Many of his studies involve connections with topics such as Endocrinology and Internal medicine.
The concepts of his Gastroenterology study are interwoven with issues in Serology and Risk factor. Stomach cancer is closely connected to Spirillaceae in his research, which is encompassed under the umbrella topic of CagA. Within one scientific family, he focuses on topics pertaining to Gastric mucosa under Immunology, and may sometimes address concerns connected to Molecular biology.
Helicobacter pylori, Internal medicine, Gastroenterology, Cancer and Antibiotic resistance are his primary areas of study. His Helicobacter pylori research integrates issues from CagA, Genotype and Microbiology. CagA is a primary field of his research addressed under Virulence.
The various areas that Yoshio Yamaoka examines in his Gastroenterology study include Biomarker, Receiver operating characteristic, Atrophy and Risk factor. His research on Cancer also deals with topics like
