Aspiration of the contents of the uterus with a vacuum curette.

Procedures for the purpose of rendering individuals incapable of reproduction.

The active form of angiotensin. An octapeptide found in blood, it is synthesized from ANGIOTENSIN I and quickly destroyed. Angiotensin II causes profound vasoconstriction with a resulting increase in blood pressure. It differs among species by the amino acid in position 5. The human form has ISOLEUCINE in this position. The clinically and experimentally used bovine form has VALINE in position 5.

A statistical technique that isolates and assesses the contributions of categorical independent variables to variation in the mean of a continuous dependent variable.

A clinical syndrome characterized by the development of CHEST PAIN at rest with concomitant transient ST segment elevation in the electrocardiogram, but with preserved exercise capacity.

Drugs used to cause dilation of the blood vessels.

A congenital anomaly characterized by clusters of dilated hypertrophic veins surrounded by normal nervous system tissue. The blood vessels have thin walls composed of a single layer of fibromuscular tissue lined by epithelium. These lesions may occur in the brain, but are more frequent in the spinal cord and spinal meninges. The incidence of hemorrhage is relatively low, but when it occurs it may be associated with venous infarctions of the nervous system. (From Davis et al., Textbook of Neuropathology, 2nd ed, pp628-9)

A group of cognitive disorders characterized by the inability to perform previously learned skills that cannot be attributed to deficits of motor or sensory function. The two major subtypes of this condition are ideomotor (see APRAXIA, IDEOMOTOR) and ideational apraxia, which refers to loss of the ability to mentally formulate the processes involved with performing an action. For example, dressing apraxia may result from an inability to mentally formulate the act of placing clothes on the body. Apraxias are generally associated with lesions of the dominant PARIETAL LOBE and supramarginal gyrus. (From Adams et al., Principles of Neurology, 6th ed, pp56-7)

Subjectively experienced sensations in the absence of an appropriate stimulus, but which are regarded by the individual as real. They may be of organic origin or associated with MENTAL DISORDERS.
