    ... ter a certain number of divisions, the clock genes are triggered and may produce proteins responsible for cell destruction (Keeton, 1992, 50). Cellular Aging In 1961, a discovery made by Leonard Hayflick showed that normal, diploid cells from such continually Areplaced@ parts of the body as skin, lungs, and bone marrow, divide a limited number of times. Although the cells stop dividing at the point just before DNA synthesis, they do not die. The longer-lived the species, the more divisions the cells undergo. As the age of an individual increases, the number of potential divisions decreases (Ricklefs and Finch, 1995, 29). This discovery was found using fibroblasts, or cells found in the c ...

    ... to aid in normal development and rehabilitation. Limb deformities and repeated fractures can be corrected by intramedullary rods -- telescoping rods that elongate with growth. After surgical placement of the rods, extensive post- operative care is required because greater amounts of blood and fluid are lost. (Loeb, 755) It should be noted that the healing of fractures appear to be normal. (Isselbacher, 2112) Braces, immobilizing devices and wheelchairs are necessary. Physical therapy is important in the treatment of OI. Bone fracture density in unfractured bone is decreased when compared with age-matched controls due to limited exercise, so it is essential to stay as active as possible. ...

  • Osteogenesis Imperfecta - 1,185 words
    Osteogenesis Imperfecta Osteogenesis imperfecta (OI) is a rare genetic disorder of collagen synthesis associated with broad spectrum of musculoskeletal problems, most notably bowing and fractures of the extremities, muscle weakness, laxity in the ligaments, and spinal deformities.(Binder, 386). Other collagen-containing skeletal tissues, such as the sclerae, the teeth, and the heart valves are also affected to a variable degree. OI has a common feature of bony fragility associated with defective formation of collagen by osteoblasts and fibroblasts(Smith, 1983, 13). This disease, involving defective development of the connective tissues, is usually the result of the autosomal dominant gene, b ...

    ... encing can be carried out in chronic villa biopsies at 8-12 weeks. There is no known treatment of OI at this time. Treatment therefore is predominantly supportive and educational. Because of multiple fractures and bruising, it is important to diagnose this disease in order to prevent accusations of child abuse. Treatment of fractures is often challenging because of abnormal bone structure and laxity of the ligaments. Splinting devices are used to stabilize the bones and to protect against additional fractures. Treatment aims to prevent deformities through use of traction and/or immobilization in order to aid in normal development and rehabilitation. Limb deformities and repeated fracture ...

  • The Cloning War: Moral Or Immoral - 1,056 words
    The Cloning War: Moral Or Immoral? The Cloning War: Moral or Immoral? Outside the lab where the cloning had actually taken place, most of us thought it could never happen. Oh we would say that perhaps at some point in the distant future, cloning might become feasible through the use of sophisticated biotechnologies far beyond those available to us now. But what we really believed, deep in our hearts, was that this was one biological feat we could never master. -Dr. Lee M. Silver, 1997 With every revolution, there must be conflict. When the great thinkers of the past decided the earth was round, or that the planets revolved around the sun, their revolution caused excommunication. When America ...
