ActivaseBrand name of alteplase, a tissue plasminogen activator made by recombinant DNA technology. See: Tissue plasminogen activator.
RELATED TERMS--------------------------------------
Alteplase
Generic name of a tissue plasminogen activator produced by recombinant DNA technology. The brand name is Activase. See: Tissue plasminogen activator.
Tissue
Biological tissue is a group of cells that perform a similar function.The study of tissues is known as histology, or, in connection with disease, histopathology.The classical tools for studying the tissues are the wax block, the tissue stain, and the optical microscope, though developments in electron microscopy, immunofluorescence, and frozen sections have all added to the sum of knowledge in the last couple of decades.

Acting out
This is the process of expressing unconscious emotional conflicts or feelings via actions rather than words. The person is not consciously aware of the meaning or etiology of such acts. Acting out may be harmful or, in controlled situations, therapeutic (e.g., children's play therapy).
Actinic
"Referring to the ultraviolet (UV) rays from sunlight and UV lamps. Sunburn is an actinic burn. An actinic keratosis is a skin lesion that is the consequence of chronic sun exposure. From the Greek ""aktis"" meaning ""ray."""
Actinic keratoses
Scaly, pink, gray or tan patches or bumps on the face or scalp, or on the back of the hands. Occur mostly on people who have light skin that has been damaged by the sun.
Actinic keratosis
A small rough spot on skin chronically exposed to the sun, precancerous, can develop into a skin cancer called squamous cell carcinoma, a process that typically takes years. Actinic keratoses occur most frequently in fair-skinned people. Common locations are the face, scalp, back of the neck, upper chest, forearm and back of the hand. Prevention is by minimizing sun exposure. Treatments include cryosurgery (freezing them with liquid nitrogen), cutting them away, burning them, putting 5-fluorouracil (5-FU) on them, and photodynamic therapy (which involves injecting into the bloodstream a chemical that collects in actinic keratoses and makes them more sensitive to exposure to a specialized form of light).
Actinolite
A basic calcium, magnesium, iron silicate, one of six naturally occurring fibrous minerals forming the group called asbestos. Occurs as translucent bright- to gray-green tough interlocking fibers which are flexible and elastic. Actinolite has not been used commercially, although it is sometimes a contaminant in asbestos-containing products.
Actinomyces
Actinomyces refers to soil-inhabiting saprophytes and disease-producing plant and animal parasites .
Actinomycetes
A group of gram-positive bacteria (order Actinomycetales) that produce various bioactive agents including antibiotics, enzymes, and vitamins. Streptomyces belong to this bacterial order.
Action potential
A photoreceptor's relative spectral sensitivity.
Action spectra
A photoreceptor's relative spectral sensitivity.
Action tremor
A tremor that increases when the hand is moving voluntarily.
Actiq
Actiq is a prescription or over-the-counter drug which is (or once was) legal in the United States and possibly in other countries. Active ingredient(s): fentanyl citrate.
Actira

Activated charcoal
Charcoal that has been heated to increase its absorptive capacity. Activated charcoal is sold as an over-the-counter (OTC) product to help relieve intestinal gas. It is also used to absorb poisons (as in gas mask filters), neutralize poisons that have been swallowed, and filter and purify liquids.
Activated leukocyte cell adhesion molecule
See: ALCAM.
Active euthanasia
"The active acceleration of a ""good"" death by use of drugs etc, whether by oneself or with the aid of a doctor. The word ""euthanasia"" comes from the Greek -- ""eu"" meaning ""goodly or well"" + ""thanatos"" meaning ""death."" So, euthanasia is literally the ""good death."" "

Activities of daily living (ADLs)
The things we normally do in daily living including any daily activity we perform for self-care (such as feeding ourselves, bathing, dressing, grooming), work, homemaking, and leisure.

PREVIOUS AND NEXT TERMS--------------------------------------
Acrylamide
A chemical created in foods when starches and other carbohydrates are overheated (over 120øC or 250øF) during cooking. There is concern that acrylamide may be a carcinogen (cause cancer). Acrylamide is used in papermaking, ore processing, permanent-press fabrics, and dye manufacture. Acrylamide is also polymerized to form polyacrylamides which are used as water-soluble stabilizers, for example, in waste water treatment and in gel electrophoresis.
