Overview

What is he best known for?

The fields of study he is best known for:

  • Internal medicine
  • Endocrinology
  • Gene

John R. G. Challis focuses on Internal medicine, Endocrinology, Fetus, Placenta and Pregnancy. His biological study focuses on Prostaglandin. The Fetus study combines topics in areas such as Endocrine system, Hypothalamic–pituitary–adrenal axis, Stimulation and Glucocorticoid.

His study in the fields of Trophoblast and Syncytiotrophoblast under the domain of Placenta overlaps with other disciplines such as Progesterone receptor. His Pregnancy research integrates issues from Obstetrics, Betamethasone, Physiology and Uterus. His Gestation research includes themes of Estrone and Peptide hormone.

His most cited work include:

  • ENDOCRINE AND PARACRINE REGULATION OF BIRTH AT TERM AND PRETERM (770 citations)
  • Inflammation and Pregnancy (609 citations)
  • Endocrine control of parturition (387 citations)

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

John R. G. Challis spends much of his time researching Internal medicine, Endocrinology, Fetus, Pregnancy and Placenta. His Internal medicine study integrates concerns from other disciplines, such as Amnion, Decidua and Fetal membrane. His work deals with themes such as Trophoblast and Gestation, which intersect with Endocrinology.

The various areas that John R. G. Challis examines in his Gestation study include Corticosteroid, Radioimmunoassay and Gestational age. His research in Fetus intersects with topics in Pituitary gland, Hypoxemia, Dexamethasone and Endocrine system. His Pregnancy research incorporates elements of Estrone, Uterus and Obstetrics.

He most often published in these fields:

  • Internal medicine (100.00%)
  • Endocrinology (98.01%)
  • Fetus (61.37%)

What were the highlights of his more recent work (between 2005-2021)?

  • Internal medicine (100.00%)
  • Endocrinology (98.01%)
  • Fetus (61.37%)

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

His primary areas of study are Internal medicine, Endocrinology, Fetus, Placenta and Pregnancy. John R. G. Challis works mostly in the field of Internal medicine, limiting it down to topics relating to Epigenetics and, in certain cases, Adult offspring, as a part of the same area of interest. Within one scientific family, he focuses on topics pertaining to Cytokine under Endocrinology, and may sometimes address concerns connected to Chemokine and Inflammation.

His study on Fetus also encompasses disciplines like

  • Gestation that connect with fields like Gestational age,
  • Betamethasone together with Hippocampal formation. He interconnects Andrology and Amnion in the investigation of issues within Placenta. His research integrates issues of Obstetrics, Urocortin, Physiology and Endocrine system in his study of Pregnancy.

Between 2005 and 2021, his most popular works were:

  • Inflammation and Pregnancy (609 citations)
  • Neuroendocrine Mechanisms in Pregnancy and Parturition (151 citations)
  • Expression of natural antimicrobials by human placenta and fetal membranes. (141 citations)

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

  • Internal medicine
  • Gene
  • Enzyme

John R. G. Challis mainly focuses on Internal medicine, Endocrinology, Placenta, Fetus and Pregnancy. His research investigates the link between Endocrinology and topics such as Gene expression that cross with problems in In vivo. His work in the fields of Trophoblast overlaps with other areas such as Amino acid transporter.

The study incorporates disciplines such as Syncytiotrophoblast, Prostaglandin, Andrology and Fetal membrane in addition to Trophoblast. The Fetus study which covers Gestation that intersects with Dexamethasone. His studies deal with areas such as Corticosteroid and Physiology as well as Pregnancy.
