Acellular vaccine
|
|
Acellular vaccineA vaccine that may contain cellular material but does not contain complete cells.
RELATED TERMS--------------------------------------
Vaccine
A preparation, often of living weakened microorganisms, that is introduced into the body to produce immunity to a specific disease by causing the formation of antibodies.
SIMILAR TERMS--------------------------------------
Acellular
Not made up of cells or divided into cells. Or lacking intact cells as, for example, an acellular vaccine which may contain cellular material but not complete cells.
PREVIOUS AND NEXT TERMS--------------------------------------
ACE (angiotensin converting enzyme)
The angiotensins are peptides (substances smaller than proteins) that act as vasoconstricting agents (causing blood vessels to narrow). Narrowing the diameter of the blood vessels sends up the blood pressure. ACE converts angiotensin to its activated form (called angiotensin II) enabling it to function. The ACE inhibitors are drugs that inhibit the formation of angiotensin II and are used for blood pressure control and congestive heart failure. The ACE inhibitors include benazepril (brand name: Lotensin), captopril (brand name: Capoten), lisinopril (brand names: Zestril and Prinivil), quinapril (brand name: Accupril), and ramipril (brand name: Altace).
ACE inhibitor
A drug that inhibits ACE (angiotensin converting enzyme) which is important to the formation of angiotensin II. Angiotensin II causes arteries in the body to constrict and thereby raises the blood pressure. ACE inhibitors lower the blood pressure by inhibiting the formation of angiotensin II. This relaxes the arteries. Relaxing the arteries not only lowers blood pressure, but also improves the pumping efficiency of a failing heart and improves cardiac output in patients with heart failure. ACE inhibitors are therefore used for blood pressure control and congestive heart failure.
ACE2 (angiotensin converting enzyme 2)
An essential regulator of heart function. Also may be involved in the embryonic development of the heart. The ACE2 gene has been mapped to the X chromosome (band Xp22).
ACEI
ACE inhibitor.
Acellular
Not made up of cells or divided into cells. Or lacking intact cells as, for example, an acellular vaccine which may contain cellular material but not complete cells.
Acellular vaccine
Acentric chromosome
"A fragment of a chromosome (one of the microscopically visible carriers of the genetic material DNA) that is lacking a centromere (the ""waist"" of the chromosome essential for the division and the retention of the chromosome in the cell) and so is lost when the cell divides."
Aceruloplasminemia
A genetic disorder in which there is absence of the protein ceruloplasmin from blood and accumulation of iron in the pancreas, liver and brain, causing diabetes and progressive neurodegeneration with the tremors and gait abnormalities characteristic of Parkinson disease.
Acetabular
"Pertaining to the acetabulum, the cup-shaped socket of the hip joint which is a key feature of the pelvis. The head (upper end) of the femur (the thighbone) fits into the acetabulum and articulates with it, forming a ball-and-socket joint. The acetabulum is not just cup-shaped. The word ""acetabulum"" in Latin means cup, a vinegar cup."
Acetabular labrum
"A ring of fibrocartilage (fibrous cartilage) that runs around the acetabulum (cup) of the hip joint and increases its depth. The head of the femur (the bone in the thigh) fits in the acetabulum. The labrum deepens this cavity and effectively increases the surface (and strength) of the hip joint. Injuries to the acetabular labrum can occur from chronic trauma due to repetitive hip motion or from acute trauma as, for example, from a direct blow to the hip or a violent motion of the hip. Signs and symptoms of a acetabular labrum injury include pain accompanying hip motion, occasional pain in the hip at night or during daily activities, decreased range of motion and loss of strength in the hip. Treatment may include anti-inflammatory medication and rest. Exercises to strengthen the hip muscles may then be recommended. If these measures are not effective, arthroscopic surgery may be done. In medicine, a labrum is a ring of fibrocartilage around the edge of the articular (joint) surface of a bone. The Latin ""labrum"" means ""lip."" The term is used generally to designate a lip, edge, or brim. Plural, labra."
Acetabulum
"The cup-shaped socket of the hip joint. In fact, in Latin an ""acetabulum"" is cup, a vinegar cup. The acetabulum is a feature of the pelvis. The head (upper end) of the femur (the thighbone) fits into the acetabulum and articulates with it, forming a ball-and-socket joint."
