APL
|
|
APL"Abbreviation for acute promyelocytic leukemia, a malignancy of the bone marrow in which there is a deficiency of mature blood cells in the myeloid line of cells and an excess of immature cells called promyelocytes. APL is due to a translocation (an exchange of chromosome material) between chromosomes 15 and 17 which is symbolized t(15;17). This translocation is not a mere marker of APL. It is the cause of APL."
RELATED TERMS--------------------------------------
Acute
1. Of short course. 2. Severe, but of a short duration. Not chronic.
Leukemia
Cancer of white blood cells. Acute leukemias are characterized by the presence of "blasts," which are immature white blood cells. Large quantities of blasts generally overgrow the bone marrow, leaving very little space for normal bone marrow cells. This type generally requires immediate treatment. Chronic leukemias are those characterized by a large and uncontrolled growth of more mature white blood cells. These types of leukemias tend not to progress as rapidly, and treatment is often milder than that of acute leukemias.
Malignancy
A tendency to worsen to a more serious illness or death. Commonly used to describe cancer.
Bone
Bone refers either to a hardened connective tissue or to one of the individual structures, or organs, into which it is formed, found in many animals. Bones support body structures, protect internal organs, and (in conjunction with muscles) facilitate movement; are also involved with cell formation, calcium metabolism, and mineral storage. The bones of an animal are, collectively, known as the skeleton.
Marrow
The tissue which fills the cavities of most bones; the medulla. In the larger cavities it is commonly very fatty, but in the smaller cavities it is much less fatty, and red or reddish in color.
Blood
The life-maintaining fluid which is made up of plasma, red blood cells (erythrocytes), white blood cells (leukocytes), and platelets; blood circulates through the body's heart, arteries, veins, and capillaries; it carries away waste matter and carbon dioxide, and brings nourishment, electrolytes, hormones, vitamins, antibodies, heat, and oxygen to the tissues.
Chromosome
A structural unit within a eukaryotic nucleus that carries genes. A chromosome consists of a long, continuous strand of DNA and associated proteins.
Chromosomes
Filaments of genetic material in every cell nucleus that are made up of genes and that transmit genetic information from one generation of cells to the next.

PREVIOUS AND NEXT TERMS--------------------------------------
Apheresis
The process of removing a specific component from blood and returning the remaining components to the donor, in order to collect more of one particular part of the blood than could be separated from a unit of whole blood. Also called hemapheresis or pheresis.
Aphrasia
The inability to speak or understand phrases.
Aphthous ulcer
A small sensitive painful ulcer crater in the lining of the mouth. Commonly called a canker sore. Aphthous ulcers are one of the most common problems that occur in the mouth. About 20% of the population (1 in 5 people) have aphthous ulcers at any given time. Aphthous ulcers typically last for 10-14 days and they heal without leaving a scar. There are many possible causes of aphthous ulcers. Often the cause is unknown.
Apical
The adjective for apex, the tip of a pyramidal or rounded structure, like the lung or the heart. For example, an apical lung tumor is a tumor located at the top of the lung.
Apiphobia
Fear of bees. A phobia is an unreasonable sort of fear that can cause avoidance and panic. Phobias are a relatively common type of anxiety disorder. Phobias can be treated with cognitive behavioral therapy using exposure and fear reduction techniques. In many cases, anti-anxiety or anti-depressant medication proves helpful, especially during the early stages of therapy.
APL
Aplasia of the breast
A rare condition wherein the normal growth of the breast or nipple never takes place. They are congenitally absent. There is no sign whatsoever of the breast tissue, areola or nipple. There is nothing there.
APLS (antiphospholipid antibody syndrome)
An immune disorder characterized by the presence of abnormal antibodies in the blood associated with abnormal blood clotting, migraine headaches, recurrent pregnancy losses (repeat spontaneous abortions), and low blood platelet counts (thrombocytopenia). The abnormal antibodies are directed against phospholipids, fats that contains phosphorous.
APM1
Adipose most abundant gene transcript 1. (AdiPose Most abundant gene transcript 1 = APM1.) The APM1 gene encodes the hormone adiponectin.
Apnea, central sleep
"Sleep apnea is a breathing disorder characterized by brief interruptions of breathing during sleep. It owes its name to a Greek word, apnea, meaning ""want of breath."""
Apnea, obstructive sleep
"Sleep apnea is a breathing disorder characterized by brief interruptions of breathing during sleep. It owes its name to a Greek word, apnea, meaning ""want of breath."" "
