Overview

What is he best known for?

The fields of study he is best known for:

  • Internal medicine
  • Gene
  • Cancer

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.

His most cited work include:

  • Traces of human migrations in Helicobacter pylori populations (778 citations)
  • An African origin for the intimate association between humans and Helicobacter pylori (716 citations)
  • Results of surgical and nonsurgical treatment for small-sized hepatocellular carcinomas: A retrospective and nationwide survey in Japan (634 citations)

What are the main themes of his work throughout his whole career to date?

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.

He most often published in these fields:

  • Helicobacter pylori (87.43%)
  • Internal medicine (42.11%)
  • Gastroenterology (33.69%)

What were the highlights of his more recent work (between 2017-2021)?

  • Helicobacter pylori (87.43%)
  • Internal medicine (42.11%)
  • Gastroenterology (33.69%)

In recent papers he was focusing on the following fields of study:

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

  • Incidence, which have a strong connection to Relative risk,
  • Helicobacter pylori infection, which have a strong connection to Immunology, Host factors, Cell integrity and Pathogenicity. His studies deal with areas such as Multiple drug resistance, Drug resistance, Intensive care medicine and Metronidazole as well as Antibiotic resistance.

Between 2017 and 2021, his most popular works were:

  • Epidemiology of Helicobacter pylori and CagA-Positive Infections and Global Variations in Gastric Cancer. (48 citations)
  • Epidemiology of Helicobacter pylori and CagA-Positive Infections and Global Variations in Gastric Cancer. (48 citations)
  • Helicobacter pylori management in ASEAN: The Bangkok consensus report (47 citations)

In his most recent research, the most cited papers focused on:

  • Internal medicine
  • Gene
  • Cancer

His main research concerns Helicobacter pylori, Internal medicine, Cancer, Gastroenterology and Intestinal metaplasia. His work carried out in the field of Helicobacter pylori brings together such families of science as Antibiotic resistance, Microbiology and Virulence. His studies in Microbiology integrate themes in fields like Inflammation, Blue light and Colony-forming unit.

His study on Cancer also encompasses disciplines like

  • Incidence that connect with fields like CagA,
  • Helicobacter pylori infection and related Immunology and MEDLINE. The study incorporates disciplines such as Primary prevention and Secondary prevention in addition to Gastroenterology. His research investigates the link between Intestinal metaplasia and topics such as Mortality rate that cross with problems in Odds ratio and Pepsin.
