  • Oncology (7.76%)

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

His primary areas of investigation include Internal medicine, Lung cancer, Oncology, Biochemistry and Pathology. When carried out as part of a general Internal medicine research project, his work on Retrospective cohort study, Asthma and Afatinib is frequently linked to work in In patient, therefore connecting diverse disciplines of study. His Lung cancer research incorporates themes from Radiology, Cancer, Carcinoma and Lung.

Enzyme, Gene, Pseudonocardia autotrophica, Vitamin and Dihomo-γ-linolenic acid are among the areas of Biochemistry where Tomohiro Tamura concentrates his study. His Enzyme study which covers Burkholderia that intersects with Triacylglycerol lipase, Docking and Gene expression. In the subject of general Gene, his work in Actinobacteria, Messenger RNA and Sequence is often linked to Synonymous substitution, thereby combining diverse domains of study.

Between 2015 and 2021, his most popular works were:

  • Prevalence, Molecular Characterization, and Antimicrobial Susceptibility of Methicillin-Resistant Staphylococcus aureus Isolated from Milk and Dairy Products. (36 citations)
  • Anodized gold surface enables mediator-free and low-overpotential electrochemical oxidation of NADH: A facile method for the development of an NAD+-dependent enzyme biosensor (13 citations)
  • Chemoenzymatically prepared konjac ceramide inhibits NGF-induced neurite outgrowth by a semaphorin 3A-like action. (9 citations)

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

  • Enzyme
  • Gene
  • DNA

His primary scientific interests are in Biochemistry, Gene, Neurite, Phosphorylation and Cell biology. Tomohiro Tamura conducts interdisciplinary study in the fields of Biochemistry and Burkholderia stabilis through his works. His study on Neurite also encompasses disciplines like

  • Signal transduction that connect with fields like Ligand, Receptor, Cell surface receptor and HaCaT,
  • Semaphorin that intertwine with fields like Collapsin response mediator protein family.

His Enzyme research integrates issues from Promoter, Gene expression, Extracellular, Expression vector and Burkholderia. His work carried out in the field of Escherichia coli brings together such families of science as Messenger RNA, Computational biology and Recombinant DNA. Tomohiro Tamura has included themes like Plasmid, Bacteriocin, Structural gene, Molecular biology and Peptide sequence in his Heterologous study.
