Physiology of the Gastrointestinal Tract

He serves as a reviewer on a variety of NIH, VA and other national study sections as well as international (European) study sections dealing with medical research in internal medicine and nutrition. He is also a member of Editorial Boards of a number of prestigious medical research journals.

Research in Dr. Said laboratory focuses on understanding cellular and molecular mechanisms involved in the transport of water-soluble vitamins (folate (vit. B), thiamine (vit. B1), riboflavin (vit. B2), pyridoxine (vit. B6), ascorbic acid (vit. C), biotin (vit. H) and niacin (vit. B3)) in the intestine, kidney, liver and pancreas. Dr. Said's laboratory has published over 160 original research papers in the gastrointestinal and nutrition fields. He has authored many chapters in scientific textbooks as well as a book in these areas. His laboratory has contributed many original discoveries to the field over the years. His research activities are funded by the VA and National Institutes of Health over the past twenty four years.

Physiology of the Gastrointestinal Tract, Sixth Edition, a Two-Volume set, covers the study of the mechanical, physical and biochemical functions of the GI Tract by linking clinical disease and disorder, thus bridging the gap between clinical and laboratory medicine while also covering breakthroughs in gastroenterology, such as the brain-gut axis and microbiome. Additionally, information is provided at the organism level, including animal models of gastrointestinal disorders and therapeutic possibilities. The book covers a wide range of conditions, from food allergies, constipation, chronic liver disease and IBS, also exploring emerging techniques to diagnose and normalize functions of the GI tract.

As a highly referenced book, this is a useful resource for gastroenterologists, physiologists, internists, professional researchers and instructors teaching courses for clinical and research students.
