Non-Randomized Controlled Trials as Topic
|
D065228 |
[Works about a study where participants are assigned to a treatment, procedure, or intervention by methods that are not random. Non-randomized clinical trials are sometimes referred to as quasi-experimental clinical trials or non-equivalent control group designs.

Non-ST Elevated Myocardial Infarction
|
D000072658 |
[A myocardial infarction that does not produce elevations in the ST segments of the ELECTROCARDIOGRAM. ST segment elevation of the ECG is often used in determining the treatment protocol (see also ST Elevation Myocardial Infarction).

Noncommunicable Diseases
|
D000073296 |
[Diseases which are typically non-infectious in origin and do not transmit from an affected individual to others. The four main types of noncommunicable diseases are CARDIOVASCULAR DISEASES (e.g., heart attacks and stroke), CANCER, chronic respiratory diseases (e.g., CHRONIC OBSTRUCTIVE PULMONARY DISEASE and ASTHMA) and DIABETES MELLITUS.

Nondisjunction, Genetic

Nonlinear Dynamics
|
D017711 |
[The study of systems which respond disproportionately (nonlinearly) to initial conditions or perturbing stimuli. Nonlinear systems may exhibit "chaos" which is classically characterized as sensitive dependence on initial conditions. Chaotic systems, while distinguished from more ordered periodic systems, are not random. When their behavior over time is appropriately displayed (in "phase space"), constraints are evident which are described by "strange attractors". Phase space representations of chaotic systems, or strange attractors, usually reveal fractal (FRACTALS) self-similarity across time scales. Natural, including biological, systems often display nonlinear dynamics and chaos.

Nonlinear Optical Microscopy
|
D000073758 |
[Microscopic imaging techniques that utilize nonlinear responses of light-matter interactions which occur with high-intensity illumination, such as from LASERS, and specialized light signal detection instrumentation to produce images without the need for dyes or fluorescent labels.

D024501 |
[A nonmuscle isoform of myosin type II found predominantly in neuronal tissue.

Nonodontogenic Cysts
|
D009631 |
[Cysts formed from epithelial inclusions in the lines of fusion of the embryonic processes which form the jaws. They include nasopalatine or incisive canal cyst, incisive papilla cyst, globulomaxillary cyst, median palatal cyst, median alveolar cyst, median mandibular cyst, and nasoalveolar cyst.

Nonoxynol
|
D017137 |
[A spermicidal contraceptive vaginal gel that contains nonoxynol-9 (N-9), available without prescription
, Nonionic surfactant mixtures varying in the number of repeating ethoxy (oxy-1,2-ethanediyl) groups. They are used as detergents, emulsifiers, wetting agents, defoaming agents, etc. Nonoxynol-9, the compound with 9 repeating ethoxy groups, is a spermatocide, formulated primarily as a component of vaginal foams and creams.

D059365 |
[An mRNA metabolic process that distinguishes a normal STOP CODON from a premature stop codon (NONSENSE CODON) and facilitates rapid degradation of aberrant mRNAs containing premature stop codons.

Nonsteroidal Anti-Androgens

Nonsuppressible Insulin-Like Activity
|
D009632 |
[A blood protein (NSILA) which mimics the biological activity of insulin in serum, but is not suppressed by insulin antibodies. During acid-ethanol extraction of Cohn fraction III, 10% of the activity is found in the supernatant (NSILA-S) and the remaining activity in the precipitate (NSILA-P). The latter is a large molecular compound, much less stable than the soluble fraction. NSILA-S is a more potent growth factor than insulin and exhibits sulfation activity.
