Researchers also found that men who smoked marijuana are doubling their risk of testicular tumors compared with men who passed on grass. In addition‚ their tumors grow at a more rapid pace than normal as well as being more resilient to fight. She also found that the use of marijuana affects their fertility and general health. As a matter of fact‚ Cortessis also found that the

Compare and contrast tumour suppressor genes and proto-oncogenes. Discuss an example of how recent advances in our understanding of these genes have led to the development of a novel therapy that is being used in the treatment of human cancer. Cancer known in medicine as a malignant neoplasm is one of the biggest killers worldwide. In 2007‚ cancer caused roughly 13% (7.9 million) of the planet’s deaths (Jemal‚ 2011). This will more greatly affect an aging society such as ours in years to come‚ and

Investigating the effectivness of PVA and PVAc as base polymers In the production of a polymer ball. Introduction A monomer refers to a specific group of atoms that from a molecular unit. When monomers are strung together like a long chain they form polymers. A good analogy of polymers‚ would be long connections of chains which become tangled like a bunch of spaghetti in a pot. The reason for experimenting with‚ and understanding polymers is because they play such a major roll and are found

P53 is a tumor suppressor gene‚ which usually stops cell division from occurring. This gene is very important during the G1/S checkpoint because it stops cell division from occurring if damaged or dangerous genetic material (DNA) is found. It then signals for enzymes‚ which are used to repair the damaged component of the DNA‚ which then allows cells with repaired DNA to divide. When DNA can’t be repaired‚ then the cell goes under apoptosis (death of the cell). However when this gene is turned

properly can be used as a remedy‚ but if used wrong it could be taken in the wrong context and separate you from others. Not everyone is able to use it appropriately though. When Jimmy came to telling his wife about the cancer he referred to his tumor as a baseball‚ in both size and shape. Not only that‚ Jimmy used his humor negatively. “No really. I told her to call me Babe Ruth. Or Roger Maris. Or maybe even Hank Aaron…”(2) This referred to fact that when Hank Aaron was about to

DNA. Monoclonal antibodies are important reagents in the treatment and diagnosis of disease. They have been used for diagnosis of pregnancy‚ detection of presence and concentration of drugs in the blood‚ histocompatibility assay‚ and detecting shed tumor antigens. They are antibodies that are mass produced in a laboratory from a single clone that recognizes only one epitope of a single antigen. Recombinant DNA is DNA that has been created artificially and codes for a specific desired protein for harvest

released as a result of this increased activation of T cells and may even induce toxic shock. This Toxic Shock Syndrome is due to Staphlyococcus aureus‚ characterized by “erythematous eruption and high fever”. An important cytokine molecule‚ TNF-alpha (tumor necrosis factor alpha)‚ is secreted amongst these cytokines and plays a vital role in the inflammatory response of the body. An over secretion of TNF-alpha may result “endothelial and vascular smooth muscle changes‚ which manifests as hypotension‚

Hippel Lindau is a disease that’s an inherited disorder characterized by the abnormal growth of both benign and cancerous tumors on the cerebellum‚ spinal cord‚ brain stem‚ or nerve root. The major cause for the Von Hippel-Lindau Syndrome is mutations in the suppressor gene‚ which keeps cell growth from going too slow or too fast. If the gene is mutated‚ it will cause a tumor to grow in one of the central nervous system. The symptoms can cause terrible headaches‚ vomiting‚ weakness and loss of muscle

Leiomymas also called fibromyomas‚ or myomas‚ uterine fibroids have an increased risk of uterine cancer and does not develop into cancer. The 70% to 80% of women have uterine fibroids sometime during their lives‚ and it remain small and asymptomatic. It is common among women ages 30 to 50 years but not common in women with menopause.
