Ernesto Sanchez BIO: 187 Instructor: Anna April 16, 2012 Duchenne Muscular Dystrophy Even though living organisms were designed to function as a perfect machine, different genetic errors occur occasionally. Many of these genetic disorders are caused by abnormalities in genes or chromosomes. In other worlds, person’s DNA strands are affected. There are many different types of genetic disorders; some are inherited from the parents, while others are caused by acquired changes, or mutations in a previous group of genes. Since generic disorders are present before birth, and the damage from these diseases are irreversible.
Cystic Fibrosis is a very serious inherited genetic disease which affects one child in every 2,500 Caucasian births. This disease usually affects the lungs and causes the build up of a thick mucus which causes chest infections. These infections unfortunately usually lead to death during childhood or early adulthood. On occasion, besides affecting the lungs, it affects the bowels and the pancreas, causing blockages in the intestines and poor absorption of food. Cystic Fibrosis may first appear in a newly born baby, or in children or young adults.
Also, bacteria can grow in mucus making the lungs susceptible to other diseases. What are the causes of Cystic Fibrosis? * Cystic fibrosis is purely hereditary meaning that it’s passed on through genes from parent to children. Over 10 million US citizens carry the cystic fibrosis gene and are not aware
Yet thousands of people die each year or escalates billions of debt to the health care system in the U.S. annually to fight them. According to the CDC these types of infections can be identified and isolated by cultures and laboratory testing. But to aid in helping battle the infections throughout the healthcare industry The Joint Commission has place accreditation requirements and various tools to reduce the infection rates in the healthcare field.

“Spooked” explored the history and hauntings of Waverly Hills. Waverly Hills has had a very historical past that many people will never know. Unless something is done, the history of Waverly Hills will be gone forever. It is estimated that the building will be completely destroyed within ten years if nothing is done to repair the damage that has occurred. Today, tuberculosis is nearly nonexistent thanks to the research that occurred at Waverly Hills and other TB sanatoriums around the world.
These mistakes result in mutation leading to loss or inappropriate expression of affected genes. Studies indicate that genetic alterations in the P53 tumor suppressor gene play an important role in the development of skin cancer. The p53 gene is also involved in apoptosis (programmed cell death), and it has been proposed that p53 serves as a “guardian of the genome” by aiding in DNA repair or by going through apoptosis to elimated cells with excessive DNA damage. Unrepaired damage in the p53 gene are transformed into mutations thereby initiating the process of carcinogenesis. Following repeated exposures to UV, keratinocytes (sunburn cells) carrying
One problem that caught my eye was the Spanish Flu pandemic that killed so many during that time. It was a serious health problem because of the fact that we lost a lot of people and there seemed to be no cure in the beginning. 675,000 Americans
Many of these patients were left with uncontrollable jerky movements, which, scientists believed, were caused because of the fetal cells. Although some patients had showed improvement, after a year, those patients also began to develop severe dyskinesia. During these processes people argued that it was unethical to destroy embryos to obtain stem cells to cure someone else. If this research would be allowed to be continued in the future, some questions that might come up include whether or not scientists should be allowed to killed fetuses to obtain the stem cells they need for the
It is released by one nerve ending also known as synapses, and is picked up by another nerve ending. After a message is sent, enzymes in the brain clean the serotonin out of the synapses. C. Main Idea: Patients with OCD have damaged receptor sites and is blocked to prevent sertonin to function potentially. D. Big Point: As Medline Plus explains, on September 25, 2007, recent data shows, that about 7 millions Americans are diagnose with OCD. About the age of 20 to 30 is when the symptoms are noticed by the abnormalities in the brain.
Sickle Cell Anemia Every year Sickle Cell Anemia claims 501 lives and affects 72,000 others. Some may ask "What is Sickle Cell Anemia?" It derived from Ancient Greek meaning "lack of blood". It is a disease passed down through families, in which hemoglobin and developed red blood cells become irregularly shaped like crescents or sickles. In addition, having this type of anemia causes the red blood cells (RBCs) to become hard and pointed.
