|
Defecography
|
D019841 |
[Radiographic examination of the process of defecation after the instillation of a CONTRAST MEDIA into the rectum.

|
Defective Viruses
|
D003673 |
[Viruses which lack a complete genome so that they cannot completely replicate or cannot form a protein coat. Some are host-dependent defectives, meaning they can replicate only in cell systems which provide the particular genetic function which they lack. Others, called SATELLITE VIRUSES, are able to replicate only when their genetic defect is complemented by a helper virus.

Defense Mechanisms
|
D003674 |
[Unconscious process used by an individual or a group of individuals in order to cope with impulses, feelings or ideas which are not acceptable at their conscious level; various types include reaction formation, projection and self reversal.

|
Defensins
|
D023082 |
[Family of antimicrobial peptides that have been identified in humans, animals, and plants. They are thought to play a role in host defenses against infections, inflammation, wound repair, and acquired immunity.

|
Defensive Medicine
|
D003675 |
[The alterations of modes of medical practice, induced by the threat of liability, for the principal purposes of forestalling lawsuits by patients as well as providing good legal defense in the event that such lawsuits are instituted.

Deferasirox
|
D000077588 |
[A triazole and benzoate derivative that acts as a selective iron chelator. It is used in the management of chronic IRON OVERLOAD due to blood transfusion or non-transfusion dependent THALASSEMIA.

|
Deferiprone
|
D000077543 |
[A pyridone derivative and iron chelator that is used in the treatment of IRON OVERLOAD in patients with THALASSEMIA.

|
Deferoxamine
|
D003676 |
[Natural product isolated from Streptomyces pilosus. It forms iron complexes and is used as a chelating agent, particularly in the mesylate form.

|
Defibrillators
|
D047548 |
[Cardiac electrical stimulators that apply brief high-voltage electroshocks to the HEART. These stimulators are used to restore normal rhythm and contractile function in hearts of patients who are experiencing VENTRICULAR FIBRILLATION or ventricular tachycardia (TACHYCARDIA, VENTRICULAR) that is not accompanied by a palpable PULSE. Some defibrillators may also be used to correct certain noncritical dysrhythmias (called synchronized defibrillation or CARDIOVERSION), using relatively low-level discharges synchronized to the patient's ECG waveform. (UMDNS, 2003)

|
Defibrillators, Implantable
|
D017147 |
[Implantable devices which continuously monitor the electrical activity of the heart and automatically detect and terminate ventricular tachycardia (TACHYCARDIA, VENTRICULAR) and VENTRICULAR FIBRILLATION. They consist of an impulse generator, batteries, and electrodes.

Deficiency Diseases
|
D003677 |
[A condition produced by dietary or metabolic deficiency. The term includes all diseases caused by an insufficient supply of essential nutrients, i.e., protein (or amino acids), vitamins, and minerals. It also includes an inadequacy of calories. (From Dorland, 27th ed; Stedman, 25th ed)

Defoliants, Chemical
|
D003678 |
[Herbicides that remove leaves from trees and growing plants. They may be either organic or inorganic. Several of the more persistent types have been used in military operations and many are toxic. (From Hawley's Condensed Chemical Dictionary, 11th ed)

Degenerin Sodium Channels
|
D062626 |
[A family of mechanosensitive sodium channels found primarily in NEMATODES where they play a role in CELLULAR MECHANOTRANSDUCTION. Degenerin sodium channels are structurally-related to EPITHELIAL SODIUM CHANNELS and are named after the fact that loss of their activity results in cellular degeneration.

Degloving Injuries
|
D000069836 |
[Avulsions of the superficial tissues of SKIN and SUBCUTANEOUS TISSUE from the underlying FASCIA.

|
Deglutition Disorders
|
D003680 |
[Difficulty in SWALLOWING which may result from neuromuscular disorder or mechanical obstruction. Dysphagia is classified into two distinct types: oropharyngeal dysphagia due to malfunction of the PHARYNX and UPPER ESOPHAGEAL SPHINCTER; and esophageal dysphagia due to malfunction of the ESOPHAGUS.

Dehalococcoides
|
D000082942 |
[A genus of organohalide-respiring bacteria in the class Dehalococcoidia and phylum CHLOROFLEXI. It can dehalogenate toxic compounds such as TETRACHLOROETHENE into less harmful chemical forms.
