Ultraviolet Radiation Nucleic Acid
1,499 words... these processes has the potential to damage the genetic material, and thus the cell. This in turn could cause cells to function poorly, causing premature aging associated with Werner syndrome. If the DNA damage happened to inactivate tumor suppressor genes or active oncogenes, it might also cause cells to grow out of control and produce cancerous tumors. In fact, there is already evidence that a faulty helicase can cause cancers. Recently a team led by geneticist James German of the New York...

Males And Females Pituitary Gland
1,352 wordsAcromegaly (Greek for appendage enlargement) is a rare but very serious disease frequently referred to as Gigantism or Giantism. It is the direct result of an overproduction and secretion of the adenohypophyseal growth hormone GH. True to its name, the disease is characterized by an enlargement of the organs, bones, and soft tissues, as well as a thickening of the skin and bodily membranes; and is frequently difficult to diagnose, as symptoms often do not appear until middle age. Typically the d...

Breast Cancer Ten Minute
1,507 wordsA lot of work has been done recently to establish a Human Genome Model, a genetic map, physical map and comparative DNA sequence of human chromosomes. This work with the Human Genome Model cannot be achieved without a small part upon the parallel implementation of gene mapping projects in other species. One of these other species which has been associated with the human recently has been the feline (1). With exception to the primates, of the non primate mammalian species with developing comparat...

Plasma Membrane Alzheimer Disease
950 wordsLipid Rafts A lipid raft is a micro domain within the membranes of cells that is cholesterol-rich. It has been believed since 1972 that, in cell membranes, membrane proteins and phospholipids are constantly and widely distributed as following a fluid mosaic model. Then in 1988, a scientist named Kai Simmons, who worked at the European Molecular Biology Laboratory located in Germany, suggested the notion that there exist micro domains, which are enriched with a lot of different kinds of lipids, s...

Syndrome Patients Ultraviolet Radiation
3,014 wordsNowadays those Werner Syndrome Abstract: Nowadays those involved in aging research view aging in terms of a genetic disease rather than as a natural, evolution-driven process by which the old make way for the young. A condition of aged friends and relatives seems terrible to conceive; they are afflicted with a ghastly wasting disease, a plague whose effects are inescapable because of our own genes. People plagued with Werner syndrome do not even have the opportunity to experience this natural pr...

Cell Division Prostate Cancer
1,104 wordsDiscuss social, ethical and biological issues associated with cancer Cancer is one of the most complex and devastating diseases that claim the life of many humans. Today there are one in three people worldwide who are affected by cancer, and almost 60 % of these people will almost certainly die. 7000 New Zealanders die every year from this disease. It is the second largest killer next to heart disease. Cancer does not just affect certain groups of people, it can affect anybody and it is not just...

Central Nervous System Spinal Cord
888 wordsSpinal Cord Regeneration Spinal cord injury can occur in many ways ranging from gunshot wounds, stab wounds and also bone displacement. These circumstances can lead to the death of neurons, and the demyelination of axons which causes some loss and damage to neurons. As Hudgins (1998) reports after a primary injury such as above, secondary injury occurs 30 minutes after and also that secondary injury is when the most critical damage occurs. This is when there is hemorrhaging in the gray matter of...
