Overview

What is he best known for?

The fields of study he is best known for:

  • Enzyme
  • Biochemistry
  • Cell membrane

His primary areas of study are Biochemistry, Cell biology, Molecular biology, Phorbol and Calcium. Many of his studies on Biochemistry involve topics that are commonly interrelated, such as Thrombin. His Cell biology research focuses on Chemotaxis and how it connects with Degranulation.

His Molecular biology research incorporates themes from MAP2K7 and Tyrosine phosphorylation. His study in Phorbol is interdisciplinary in nature, drawing from both Cell aggregation, Pertussis toxin, Intracellular pH and Protein kinase A. The various areas that Ramadan I. Sha'afi examines in his Calcium study include Endocrinology, Stimulation and Cytoskeleton.

His most cited work include:

  • Vascular Endothelial Cell Adherens Junction Assembly and Morphogenesis Induced by Sphingosine-1-Phosphate (861 citations)
  • p38 Mitogen-Activated Protein Kinase Activation Is Required for Human Neutrophil Function Triggered by TNF-α or FMLP Stimulation (332 citations)
  • The cytoplasmic concentration of free calcium in platelets is controlled by stimulators of cyclic AMP production (PGD2, PGE1, forskolin). (194 citations)

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

Ramadan I. Sha'afi spends much of his time researching Biochemistry, Calcium, Cell biology, Chemotaxis and Phorbol. As part of his studies on Biochemistry, Ramadan I. Sha'afi often connects relevant areas like Biophysics. His Calcium study incorporates themes from Extracellular and Endocrinology.

Ramadan I. Sha'afi interconnects Cytoskeleton and Neutrophil degranulation in the investigation of issues within Cell biology. His research in Chemotaxis intersects with topics in Cell, Cytochalasin B, Degranulation and Metabolism. Ramadan I. Sha'afi has included themes like Diacylglycerol kinase, Cytosol, Platelet-activating factor, Intracellular pH and Phosphatidylinositol in his Phorbol study.

He most often published in these fields:

  • Biochemistry (56.90%)
  • Calcium (33.62%)
  • Cell biology (26.72%)

What were the highlights of his more recent work (between 1993-2018)?

  • Cell biology (26.72%)
  • Molecular biology (22.41%)
  • MAP2K7 (6.03%)

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

Ramadan I. Sha'afi mainly investigates Cell biology, Molecular biology, MAP2K7, MAP kinase kinase kinase and Mitogen-activated protein kinase kinase. His research in Cell biology focuses on subjects like Endothelial stem cell, which are connected to Angiogenesis. His Molecular biology research includes elements of Phosphorylation and Tyrosine phosphorylation.

Ramadan I. Sha'afi has researched MAP kinase kinase kinase in several fields, including Cyclin-dependent kinase 9, Cyclin-dependent kinase 2 and ASK1. His study on Kinase activity is covered under Biochemistry. Ramadan I. Sha'afi performs multidisciplinary study on Biochemistry and In vivo in his works.

Between 1993 and 2018, his most popular works were:

  • Vascular Endothelial Cell Adherens Junction Assembly and Morphogenesis Induced by Sphingosine-1-Phosphate (861 citations)
  • p38 Mitogen-Activated Protein Kinase Activation Is Required for Human Neutrophil Function Triggered by TNF-α or FMLP Stimulation (332 citations)
  • Cytoplasmic phospholipase A2 translocates to membrane fraction in human neutrophils activated by stimuli that phosphorylate mitogen-activated protein kinase. (128 citations)

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

  • Enzyme
  • Cell membrane
  • Biochemistry

His scientific interests lie mostly in Cell biology, ASK1, MAP kinase kinase kinase, Mitogen-activated protein kinase kinase and Cyclin-dependent kinase 2. His Cell biology research is multidisciplinary, incorporating elements of Endothelial stem cell and Angiogenesis. His study in ASK1 is interdisciplinary in nature, drawing from both MAPK7, MAPK14 and MAP2K7.

Ramadan I. Sha'afi works mostly in the field of MAPK7, limiting it down to topics relating to Protein Kinase A Inhibitor and, in certain cases, Molecular biology. His research on MAP2K7 concerns the broader Biochemistry. His Mitogen-activated protein kinase study combines topics in areas such as Tyrosine and Protein kinase A.
