Double Effect Principle
|
D034723 |
[Guideline for determining when it is morally permissible to perform an action to pursue a good end with knowledge that the action will also bring about bad results. It generally states that, in cases where a contemplated action has such double effect, the action is permissible only if: it is not wrong in itself; the bad result is not intended; the good result is not a direct causal result of the bad result; and the good result is "proportionate to" the bad result. (from Solomon, "Double Effect," in Becker, The Encyclopedia of Ethics, 1992)

Double Outlet Right Ventricle
|
D004310 |
[Incomplete transposition of the great vessels in which both the AORTA and the PULMONARY ARTERY arise from the RIGHT VENTRICLE. The only outlet of the LEFT VENTRICLE is a large ventricular septal defect (VENTRICULAR SEPTAL DEFECTS or VSD). The various subtypes are classified by the location of the septal defect, such as subaortic, subpulmonary, or noncommitted.
, A subtype with pulmonary ventricular septal defect.
, A subtype with ventricular septal defect clearly away from the semilunar valves of the AORTA and the PULMONARY ARTERY.

Double-Balloon Enteroscopy

Double-Stranded RNA Binding Motif
|
D000071241 |

Down Syndrome
|
D004314 |
[A chromosome disorder associated either with an extra chromosome 21 or an effective trisomy for chromosome 21. Clinical manifestations include hypotonia, short stature, brachycephaly, upslanting palpebral fissures, epicanthus, Brushfield spots on the iris, protruding tongue, small ears, short, broad hands, fifth finger clinodactyly, Simian crease, and moderate to severe INTELLECTUAL DISABILITY. Cardiac and gastrointestinal malformations, a marked increase in the incidence of LEUKEMIA, and the early onset of ALZHEIMER DISEASE are also associated with this condition. Pathologic features include the development of NEUROFIBRILLARY TANGLES in neurons and the deposition of AMYLOID BETA-PROTEIN, similar to the pathology of ALZHEIMER DISEASE. (Menkes, Textbook of Child Neurology, 5th ed, p213)

Down-Regulation
|
D015536 |
[A negative regulatory effect on physiological processes at the molecular, cellular, or systemic level. At the molecular level, the major regulatory sites include membrane receptors, genes (GENE EXPRESSION REGULATION), mRNAs (RNA, MESSENGER), and proteins.
, A negative regulatory process that decreases ligand-receptor interactions. Reduction in receptor binding after ligand exposure can result from the internalization of ligand-receptor complex, an increase in receptor degradation, and/or a decrease in gene expression resulting in a decrease in receptor biosynthesis.

Doxepin
|
D004316 |
[A dibenzoxepin tricyclic compound. It displays a range of pharmacological actions including maintaining adrenergic innervation. Its mechanism of action is not fully understood, but it appears to block reuptake of monoaminergic neurotransmitters into presynaptic terminals. It also possesses anticholinergic activity and modulates antagonism of histamine H(1)- and H(2)-receptors.
