Overview

What is he best known for?

The fields of study he is best known for:

  • Internal medicine
  • Enzyme
  • Endocrinology

Kenneth J. Ryan focuses on Internal medicine, Endocrinology, Estrone, Estrogen and Androstenedione. His research in Androgen, Luteinizing hormone, Ovarian follicle, Insulin and Testosterone are components of Internal medicine. Kenneth J. Ryan is interested in Hormone, which is a field of Endocrinology.

His studies in Estrone integrate themes in fields like Pituitary gland, Radioimmunoassay, Peripheral plasma and Estradiol 17β. His work is dedicated to discovering how Estrogen, Metabolism are connected with Central nervous system, Estriol and Steroid and other disciplines. His Androstenedione study combines topics from a wide range of disciplines, such as Aromatization, Cotinine, Dihydrotestosterone and Limbic system.

His most cited work include:

  • The formation of estrogens by central neuroendocrine tissues (714 citations)
  • Insulin Stimulates Androgen Accumulation in Incubations of Ovarian Stroma Obtained from Women with Hyperandrogenism (545 citations)
  • Biological Aromatization of Steroids (521 citations)

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

His primary areas of study are Internal medicine, Endocrinology, Estrone, Pregnancy and Estrogen. Aromatase, Androgen, Theca, Ovarian follicle and Steroid are among the areas of Internal medicine where the researcher is concentrating his efforts. His Endocrinology study is mostly concerned with Testosterone, Androstenedione, Luteinizing hormone, Hormone and Ovary.

His research in Androstenedione intersects with topics in Aromatization and Dihydrotestosterone. His work in the fields of Gestation, Fetus and Gestational age overlaps with other areas such as Amniocentesis. Kenneth J. Ryan interconnects Physiology and Metabolism in the investigation of issues within Estrogen.

He most often published in these fields:

  • Internal medicine (63.03%)
  • Endocrinology (62.61%)
  • Estrone (20.59%)

What were the highlights of his more recent work (between 1982-2020)?

  • Endocrinology (62.61%)
  • Internal medicine (63.03%)
  • Obstetrics (10.08%)

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

His scientific interests lie mostly in Endocrinology, Internal medicine, Obstetrics, Pregnancy and Gynecology. His research combines Aromatase and Endocrinology. Many of his studies on Internal medicine involve topics that are commonly interrelated, such as In vitro.

His Obstetrics research is multidisciplinary, relying on both Offspring, Anesthesia, Abortion, Premature labor and Hematocrit levels. His Pregnancy research includes themes of Family planning and Confounding. His Gynecology research is multidisciplinary, incorporating elements of Medical therapy, Medical ethics and Psychosomatic aspects.

Between 1982 and 2020, his most popular works were:

  • Insulin Stimulates Androgen Accumulation in Incubations of Ovarian Stroma Obtained from Women with Hyperandrogenism (545 citations)
  • Hyperandrogenism, insulin resistance, and acanthosis nigricans syndrome: A common endocrinopathy with distinct pathophysiologic features (235 citations)
  • Hyperandrogenism, insulin resistance, and acanthosis nigricans syndrome: A common endocrinopathy with distinct pathophysiologic features (235 citations)

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

  • Internal medicine
  • Enzyme
  • Endocrinology

His primary scientific interests are in Internal medicine, Endocrinology, Obstetrics, Pregnancy and Insulin. His Internal medicine and Aromatase, Androstenedione, Theca, Ovary and Follicular phase investigations all form part of his Internal medicine research activities. In Androstenedione, Kenneth J. Ryan works on issues like Dihydrotestosterone, which are connected to Polycystic ovary, Steroid biosynthesis, Luteinizing hormone and Somatomedin.

In his research, he undertakes multidisciplinary study on Endocrinology and Hexamethonium compound. The concepts of his Obstetrics study are interwoven with issues in Anesthesia, Hematocrit, Anemia, Hematocrit levels and Premature labor. Kenneth J. Ryan combines subjects such as Gynecology and Confounding with his study of Pregnancy.
