| stress riser | A mechanical defect, such as a hole, in bone or other materials that concentrates stress in the area. (05 Mar 2000) |
|---|---|
| stress shielding | Osteopenia occurring in bone as the result of removal of normal stress from the bone by an implant. (05 Mar 2000) |
| stress-strain curve | A curve showing the ratio of deformation to load during the testing of a material in tension. (05 Mar 2000) |
| stress ulcers | An ulcer of the duodenum in a patient with extensive superficial burns, intracranial lesions, or severe bodily injury. Synonym: stress ulcers. (05 Mar 2000) |
| stress urinary incontinence | Leakage of urine as a result of coughing, straining, or some sudden voluntary movement, due to weakness of the fascia muscles and at the neck of the bladder. Synonym: urinary exertional incontinence. (05 Mar 2000) |
| dental stress analysis | The description and measurement of the various factors that produce physical stress upon dental restorations, prostheses, or appliances, materials associated with them, or the natural oral structures. (12 Dec 1998) |
| oxidative stress | A highly oxidized environment within cells that is thought to promote HIV replication because cells are forced into a highly activated state due to loss of control of their regulatory systems. (09 Oct 1997) |
| tensile stress | A stress acting on a body per unit cross-sectional area so as to elongate the body. (05 Mar 2000) |
| yield stress | The critical stress that must be applied to a material before it begins to flow, as in a Bingham plastic. (05 Mar 2000) |
| urinary incontinence, stress | The involuntary discharge of urine as a result of anatomic displacement which exerts an opening pull on the bladder orifice. It often occurs during coughing or other forceful stresses. (12 Dec 1998) |
| fractures, stress | Fractures due to the strain caused by repetitive exercise. They are thought to arise from a combination of muscle fatigue and bone failure, and occur in situations where bone remodeling predominates over repair. The classical stress fracture is the march fracture of military personnel, in which the metatarsal undergoes repeated stress during marching. The most common sites of stress fractures are the metatarsus, fibula, tibia, and femoral neck. (12 Dec 1998) |
| life stress | Events or experiences that produce severe strain, e.g., failure on the job, marital separation, loss of a love object. (05 Mar 2000) |
| abortifacient agents, non-steroidal | Non-steroidal chemical compounds with abortifacient activity. (12 Dec 1998) |
| acute non-lymphocytic leukaemia | <haematology> A form of leukaemia which is characterised by the proliferation of immature bone marrow precursor cells in the marrow and immature white blood cells (granulocytes) in the bloodstream. Occurs primarily in adults and in infants under 1 year of age. Complications include abnormal bleeding and susceptibility to infections. Symptoms include fatigue, weight loss, fevers, weakness, pallor, bone pains, bleeding gums, nosebleeds, easy bruising, enlarged lymph nodes and joint pains. Trisomy-8 is the most common cytogenetic abnormality observed, followed by monosomy-7 and monosomy-5. Approximately 8% of cases show trisomy-8, mostly in AML (M1), AM (M4) and acute monocytic leukaemia (M5). Many pre-leukaemic conditions, acute non-lymphocytic leukaemia and secondary leukemia show monosomy-7 or deletion of the long arm of chromosome 7. Treatment includes chemotherapy and/or bone marrow transplant. Acronym: ANLL Incidence: 2.5 cases per 100,000 (all ages). Origin: Gr. Haima = blood (07 Apr 1998) |
| analgesics, non-narcotic | Drugs that have principally analgesic, antipyretic, and anti-inflammatory actions. They do not bind to opioid receptors and are not classified under the controlled substances act. (12 Dec 1998) |
