Overview

What is he best known for?

The fields of study he is best known for:

  • Internal medicine
  • Pharmacology
  • Botany

Johji Yamahara mainly focuses on Internal medicine, Endocrinology, Glycoside, Biochemistry and Pharmacology. His study in the field of Triglyceride and Postprandial is also linked to topics like Genetic model and Oleanolic acid. When carried out as part of a general Endocrinology research project, his work on Diabetes mellitus, Glucose transporter and Lipoprotein lipase is frequently linked to work in Momordin, therefore connecting diverse disciplines of study.

Johji Yamahara is conducting research in Stereochemistry and Botany as part of his Glycoside study. His Stereochemistry study combines topics from a wide range of disciplines, such as Oral administration, Saussurea lappa, Pharmacognosy and Aesculus hippocastanum. His Pharmacology study incorporates themes from Azoxymethane, Carcinogen, Ratón, Serotonin and Anticarcinogen.

His most cited work include:

  • Anti-diabetic action of Punica granatum flower extract: activation of PPAR-gamma and identification of an active component. (198 citations)
  • Punica granatum flower extract, a potent α-glucosidase inhibitor, improves postprandial hyperglycemia in Zucker diabetic fatty rats (189 citations)
  • The inhibitory effects of mangiferin, a naturally occurring glucosylxanthone, in bowel carcinogenesis of male F344 rats. (171 citations)

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

His scientific interests lie mostly in Traditional medicine, Stereochemistry, Glycoside, Pharmacognosy and Pharmacology. His Traditional medicine research is multidisciplinary, incorporating perspectives in Terpene and Rhamnaceae, Botany. His work on Lactone as part of general Stereochemistry study is frequently linked to Hydrangea macrophylla, therefore connecting diverse disciplines of science.

His study on Glycoside is mostly dedicated to connecting different topics, such as Aesculus hippocastanum. Johji Yamahara has included themes like Rhizome and Terpenoid in his Pharmacognosy study. His Oral administration study is within the categories of Internal medicine and Endocrinology.

He most often published in these fields:

  • Traditional medicine (27.63%)
  • Stereochemistry (22.18%)
  • Glycoside (19.84%)

What were the highlights of his more recent work (between 1999-2019)?

  • Internal medicine (19.07%)
  • Endocrinology (19.07%)
  • Triglyceride (4.28%)

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

Johji Yamahara mostly deals with Internal medicine, Endocrinology, Triglyceride, Salacia oblonga and Diabetes mellitus. His Endocrinology study integrates concerns from other disciplines, such as Fibrosis, Receptor and Fatty acid. Triglyceride is a subfield of Biochemistry that Johji Yamahara explores.

His Biochemistry research incorporates elements of Inflammation and Food science. Johji Yamahara combines subjects such as Pharmacognosy and Sucrose with his study of Postprandial. His Pharmacology study focuses on Oral administration in particular.

Between 1999 and 2019, his most popular works were:

  • Anti-diabetic action of Punica granatum flower extract: activation of PPAR-gamma and identification of an active component. (198 citations)
  • Punica granatum flower extract, a potent α-glucosidase inhibitor, improves postprandial hyperglycemia in Zucker diabetic fatty rats (189 citations)
  • The inhibitory effects of mangiferin, a naturally occurring glucosylxanthone, in bowel carcinogenesis of male F344 rats. (171 citations)

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

  • Internal medicine
  • Pharmacology
  • Organic chemistry

Johji Yamahara focuses on Internal medicine, Endocrinology, Diabetes mellitus, Pharmacology and Peroxisome proliferator-activated receptor. His study in Endocrinology focuses on Insulin receptor in particular. His work on Type 2 diabetes as part of general Diabetes mellitus research is frequently linked to Nuclear receptor, bridging the gap between disciplines.

Johji Yamahara interconnects Pathology, Dyslipidemia, Anticarcinogen and Carcinogen in the investigation of issues within Pharmacology. His research on Peroxisome proliferator-activated receptor concerns the broader Biochemistry. His Triglyceride research includes elements of Carnitine and Hyperlipidemia.
