A contactin subtype that plays a role in axon outgrowth, axon fasciculation, and neuronal migration.
A family of immunoglobulin-related cell adhesion molecules that are involved in NERVOUS SYSTEM patterning.
Physical and biological barriers to the spread of potentially hazardous biologically active agents such as bacteria, viruses, recombinant nucleotides, or contaminated bio-specimens.
Overlapping of cloned or sequenced DNA to construct a continuous region of a gene, chromosome or genome.
contiguous gene microdeletion syndrome involving ABCD1and BCAP31
A negative shift of the cortical electrical potentials that increases over time. It is associated with an anticipated response to an expected stimulus and is an electrical event indicative of a state of readiness or expectancy.
Health care provided on a continuing basis from the initial contact, following the patient through all phases of medical care.
mutation in KCNA1
A technique of respiratory therapy, in either spontaneously breathing or mechanically ventilated patients, in which airway pressure is maintained above atmospheric pressure throughout the respiratory cycle by pressurization of the ventilatory circuit.

Prevention of CONCEPTION by blocking fertility temporarily, or permanently (STERILIZATION, REPRODUCTIVE). Common means of reversible contraception include NATURAL FAMILY PLANNING METHODS; CONTRACEPTIVE AGENTS; or CONTRACEPTIVE DEVICES.
Behavior patterns of those practicing CONTRACEPTION.
Methods of contraception in which physical, chemical, or biological means are used to prevent the SPERM from reaching the fertilizable OVUM.
Contraceptive methods based on immunological processes and techniques, such as the use of CONTRACEPTIVE VACCINES.
Means of postcoital intervention to avoid pregnancy, such as the administration of POSTCOITAL CONTRACEPTIVES to prevent FERTILIZATION of an egg or implantation of a fertilized egg (OVUM IMPLANTATION).
Chemical substances that prevent or reduce the probability of CONCEPTION.
Chemical substances or agents with contraceptive activity in females. Use for female contraceptive agents in general or for which there is no specific heading.
Chemical substances or agents with contraceptive activity in males. Use for male contraceptive agents in general or for which there is no specific heading.
Devices that diminish the likelihood of or prevent conception. (From Dorland, 28th ed)
Contraceptive devices used by females.
Contraceptive devices used by males.
Compounds, usually hormonal, taken orally in order to block ovulation and prevent the occurrence of pregnancy. The hormones are generally estrogen or progesterone or both.
Fixed drug combinations administered orally for contraceptive purposes.
Oral contraceptives which owe their effectiveness to hormonal preparations.
Drugs administered orally and sequentially for contraceptive purposes.
Oral contraceptives which owe their effectiveness to synthetic preparations.
Contraceptive substances to be used after COITUS. These agents include high doses of estrogenic drugs; progesterone-receptor blockers; ANTIMETABOLITES; ALKALOIDS, and PROSTAGLANDINS.
Postcoital contraceptives which owe their effectiveness to hormonal preparations.
Postcoital contraceptives which owe their effectiveness to synthetic preparations.
Outside services provided to an institution under a formal financial agreement.
Proteins which participate in contractile processes. They include MUSCLE PROTEINS as well as those found in other cells and tissues. In the latter, these proteins participate in localized contractile events in the cytoplasm, in motile activity, and in cell aggregation phenomena.
Agreements between two or more parties, especially those that are written and enforceable by law (American Heritage Dictionary of the English Language, 4th ed). It is sometimes used to characterize the nature of the professional-patient relationship.
Prolonged shortening of the muscle or other soft tissue around a joint, preventing movement of the joint.
Substances used to allow enhanced visualization of tissues.
The ability to detect sharp boundaries (stimuli) and to detect slight changes in luminance at regions without distinct contours. Psychophysical measurements of this visual function are used to evaluate VISUAL ACUITY and to detect eye disease.
An injury in which the damage is located on the opposite side of the primary impact site. A blow to the back of head which results in contrecoup injury to the frontal lobes of the brain is the most common type.
Groups that serve as a standard for comparison in experimental studies. They are similar in relevant characteristics to the experimental group but do not receive the experimental intervention.
A study in which observations are made before and after an intervention, both in a group that receives the intervention and in a control group that does not.
A work that reports on a clinical trial involving one or more test treatments, at least one control treatment, specified outcome measures for evaluating the studied intervention, and a bias-free method for assigning patients to the test treatment. The treatment may be drugs, devices, or procedures studied for diagnostic, therapeutic, or prophylactic effectiveness. Control measures include placebos, active medicine, no-treatment, dosage forms and regimens, historical comparisons, etc. When randomization using mathematical techniques, such as the use of a random numbers table, is employed to assign patients to test or control treatments, the trial is characterized as a RANDOMIZED CONTROLLED TRIAL.
