Tumors or cancer of the DIGESTIVE SYSTEM.
Diseases in any part of the GASTROINTESTINAL TRACT or the accessory organs (LIVER; BILIARY TRACT; PANCREAS).
A group of organs stretching from the MOUTH to the ANUS, serving to breakdown foods, assimilate nutrients, and eliminate waste. In humans, the digestive system includes the GASTROINTESTINAL TRACT and the accessory glands (LIVER; BILIARY TRACT; PANCREAS).
Properties and processes of the DIGESTIVE SYSTEM and DENTITION as a whole or of any of its parts.
Properties and processes of the DIGESTIVE SYSTEM as a whole or of any of its parts.
Biological actions and events that constitute the functions of the DIGESTIVE SYSTEM.
An abnormal passage communicating between any components of the digestive system, or between any part of the digestive system and surrounding organ(s).
Generally refers to the digestive structures stretching from the MOUTH to ANUS, but does not include the accessory glandular organs (LIVER; BILIARY TRACT; PANCREAS).
A histamine H1 antagonist used as the hydrogen fumarate in hay fever, rhinitis, allergic skin conditions, and pruritus. It causes drowsiness.
Tumors or cancer of the GASTROINTESTINAL TRACT, from the MOUTH to the ANAL CANAL.
Congenital structural abnormalities of the DIGESTIVE SYSTEM.
Methods and procedures for the diagnosis of diseases or dysfunction of the digestive system or its organs or demonstration of their physiological processes.
Diseases in any segment of the GASTROINTESTINAL TRACT from ESOPHAGUS to RECTUM.
The section of the alimentary canal from the STOMACH to the ANAL CANAL. It includes the LARGE INTESTINE and SMALL INTESTINE.
A nodular organ in the ABDOMEN that contains a mixture of ENDOCRINE GLANDS and EXOCRINE GLANDS. The small endocrine portion consists of the ISLETS OF LANGERHANS secreting a number of hormones into the blood stream. The large exocrine portion (EXOCRINE PANCREAS) is a compound acinar gland that secretes several digestive enzymes into the pancreatic ductal system that empties into the DUODENUM.
Wormlike or grublike stage, following the egg in the life cycle of insects, worms, and other metamorphosing animals.
An organ of digestion situated in the left upper quadrant of the abdomen between the termination of the ESOPHAGUS and the beginning of the DUODENUM.
Accumulation of a drug or chemical substance in various organs (including those not relevant to its pharmacologic or therapeutic action). This distribution depends on the blood flow or perfusion rate of the organ, the ability of the drug to penetrate organ membranes, tissue specificity, protein binding. The distribution is usually expressed as tissue to plasma ratios.
Factors which produce cessation of all vital bodily functions. They can be analyzed from an epidemiologic viewpoint.
Tumors or cancer of the STOMACH.
New abnormal growth of tissue. Malignant neoplasms show a greater degree of anaplasia and have the properties of invasion and metastasis, compared to benign neoplasms.
Endoscopic examination, therapy or surgery of the digestive tract.
A country spanning from central Asia to the Pacific Ocean.
Individuals whose ancestral origins are in the southeastern and eastern areas of the Asian continent.
Tumors or cancer of the LIVER.
Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories.
The relationships of groups of organisms as reflected by their genetic makeup.
A latent susceptibility to disease at the genetic level, which may be activated under certain conditions.
Elements of limited time intervals, contributing to particular results or situations.
Surgery performed on the digestive system or its parts.
An aspect of personal behavior or lifestyle, environmental exposure, or inborn or inherited characteristic, which, on the basis of epidemiologic evidence, is known to be associated with a health-related condition considered important to prevent.
The regular and simultaneous occurrence in a single interbreeding population of two or more discontinuous genotypes. The concept includes differences in genotypes ranging in size from a single nucleotide site (POLYMORPHISM, SINGLE NUCLEOTIDE) to large nucleotide sequences visible at a chromosomal level.
The process of breakdown of food for metabolism and use by the body.
Component of the NATIONAL INSTITUTES OF HEALTH. It conducts and supports basic and applied research for a national program in diabetes, endocrinology, and metabolic diseases; digestive diseases and nutrition; and kidney, urologic, and hematologic diseases. It was established in 1948.
Persons who have experienced a prolonged survival after serious disease or who continue to live with a usually life-threatening condition as well as family members, significant others, or individuals surviving traumatic life events.
