This system is called nucleotide excision repair and it is one of many systems that helps repair genes in the body. When it comes to Xeroderma Pigmentosum (XP) this is not the case, the nucleotide excision repair is not working in this disease, causing this persons DNA to stay damaged and has a phenotype with an OMIM number of 278700 (McKusik, 1986) . This disease is not only brutal to ones DNA but because their body cannot repair the DNA when exposed to UV light for even a minute it can have drastic affects. This disease was really described by two dermatologists from Vienna. They described the disease as xeroderma, which means parchment skin and then later added on the word pigmetnosum
Unit 4222-265 Causes and spread of Infection. outcome1: Understand the causes of infections 1:1 Identify the differences between bacteria, viruses, fungi and parasites. Infections are the result of the body’s inability to fight off microorganisms that cause disease or infection: Bacteria, viruses, fungi and parasites. Bacteria are organisms that are found almost everywhere. They are found naturally in humans, as well as plants and animals.
This compound was once used as a pesticide for killing insects in stored grain. The elimination of this product has assisted my liver indirectly in living a longer and healthier life and acquiring a better nights sleep not having to worry about it. d) Trichloroethane was used as the key thinning ingredient in the liquid form of White Out. Fatalities were linked directly to this ingredient, and its subsequent elimination from the market has saved my emotions considerable effort considering my 6 year old son eats anything he can get his hands on, including glue and white out. e) Bromomethane is used to prepare Bermuda grass on golf courses.
It is a powerful antioxidant and as such helps to protect the cells in our bodies from damage. Studies in humans have shown that lycopene is protective against a variety of cancers including prostate of course, but also colorectal, breast, lung, endometrial, pancreatic, bladder, cervical and skin cancers. Lycopene has also been shown to help prevent heart disease and may slow the development of cataracts and macular degeneration, an age related vision problem that can lead to blindness. The vitamin B6, niacin, potassium, and folate found in abundance in tomatoes are potent protectors against heart disease. Niacin can lower high cholesterol levels and potassium has been shown to lower high blood pressure and to reduce the risk of heart disease.
Hair takes on a bleached appearance, while skin becomes darker. Precautions should be taken to limit exposure to ultraviolet light to prevent skin and hair damage. Some of the sun's rays are beneficial, but others, such as ultraviolet rays, are hazardous. This radiation comes in three forms: ultraviolet A (UVA), ultraviolet B (UVB) and ultraviolet C (UVC). The earth's atmosphere filters out UVC radiation, but UVA and UVB affect you every day.
Finally, it will be much easier to get the dozen servings of fruits and vegetables that your body craves. You will find these too improve your immune system and your mood. Children should be allowed to play in the dirt, new research suggests Children should be allowed to play in the dirt because being too clean can impair the skin’s ability to heal itself, new research suggests. Scientists have discovered that bacteria on the surface of the skin play an important role in combating inflammation when we get hurt. The bugs dampen down overactive immune responses, which can lead to rashes or cause cuts and bruises to become swollen and painful.
Studies show that UVB rays are responsible for this effect. The first step in UV skin carcinogenesis (creation of cancer) involves DNA damage. Occasional mistakes of DNA repairs lead to the integration of incorrect bases into the genetic material. The DNA that is left unrepaired may disrupt cellular processes by disrupting the DNA and RNA synthesizing machineries with incorrect genetic sequenses. These mistakes result in mutation leading to loss or inappropriate expression of affected genes.
E.g. of antibiotic Penicillin G Damage the cell membrane: causes the cell to take up too much water and lyse by increasing the permeability of the cell membrane. E.g. of antibiotic is Polymyxin B Interfere with protein synthesis: prevents the productions of protein in the invading bacterial cells. E.g.
Migratory birds like the water fowl have the potential to spread the resistance bacteria over a large area, like water sources, and our soil. This spreads it to other species and makes then antibiotic resistant to the different bacteria’s. They also found that in the pre-antibiotic age that there were strains of antibiotic resistance gene’s been present before the widespread distribution of antibiotics. So this tells us that it can occur naturally in nature. It also tells us that it is important in nature.
Some observers believe that self-replicating itself should be strictly banned as the only way to fend off the threat of some engineered molecular system running rampant (Brown, 2004). They also can lead to the accidental or deliberate creation of pathogenic biological components (Brown, 2004). Molecular engineering is any means of manufacturing molecules. It may be used to create, on an extremely small scale, most typically one at a time, new molecules which may not exist in nature, or be stable beyond a very narrow range of conditions. this is an extremely difficult process, requiring manual manipulation of molecules using such devices as a scanning
