Cystic Fibrosis
Cystic Fibrosis is a lung disease caused by a mutated gene. This gene called the CFTR gene causes a protein to not allow salt or water to flow through a cell properly. This produces a thick, sticky mucus to collect in the lungs and other organs. In order for a person to get this disease, the parents both have to be carriers of this disease. Usually a person is diagnosed within the first year of life. In the United States 1 in 2,500 to 3,500 Caucasian Americans, 1 in 17,000 African-Americans, and 31,000 Asian-Americans will have this disease.
A parent might notice differences in their child if they have this disease. As a baby, a child’s skin may taste salty when kissed, or not be able to have bowel movements at first. As the child progresses in age persistent coughing, at least 3 times as often than an unaffected person, common infections, and poor growth or weight. Later in life, ducts in the liver, the biliary tract and the pancreas are affected. These blocked ducts reduce the secretion of digestive enzymes and disrupt the breakdown of the absorption of food. Some ways to tell if a person has cystic fibrosis is to do a number of tests. These test are necessary because a person with cystic fibrosis does not look sick from the outside, they look healthy. Blood tests, lung function tests, sweat tests, and chest x-rays are the most common types of diagnosis procedures.
Blood tests will show that there is a mutated gene. Lung function tests will show how well the capacity of lungs are. If the FEC1/FVC (Expiratory volume-one second/ Forced Vital Capacity) is equal to or greater than 80% the patient is in normal range. Sweat tests show a high chloride level because of the salt in the cells. Chest x-rays show the flu...

... cause. Many of these events are held all year round. This helps to create a constant flow of support and funding. This allows the laboratories to work on medications and research throughout the length of the year. With so many people, this disease is the most supported disease in the world besides HIV/AIDS.
In Conclusion, cystic fibrosis is a dangerous, uncured, and widespread disease. Treatments and medications are available to lessen the effects of the disease, but they will not always keep the disease at bay. It is important to be aware of the risks and dangers. The more people are aware of this disease the more likely scientists and medical specialists may find a breakthrough in the cure. This would save many people in the world from dying young. That is why many of the people with this disease try to live life to the fullest and make everyday special for them.

Essay on Lung Cancer : The Leading Cause Of Cancer

- Lung cancer is the leading cause of cancer related deaths in the world, comprised of a group of aggressive malignant tumors of the lower respiratory tract[1]. According to a recent statistics published by American cancer society, lung cancer alone causes more deaths than pancreas, colon, prostate and breast cancer deaths combined (Fig. 1). Furthermore, the survival rate of patients suffering from lung cancer is also extremely poor in both developed and developing parts of the world[2]. It has been reported that only 15% of lung cancer patients survive 5 or more years after been diagnosed with the disease[3]....   [tags: Cancer, Lung cancer, Oncology, Mutation]

The Main Types of Lung Cancer Essay

- Lung cancer is a disease of uncontrolled cell growth in tissues of the lung. This growth may lead to metastasis to adjacent tissues and infiltration beyond the lungs. The majority of primary lung cancers are derived from epithelial cells. Lung cancer is the most common cause of cancer-related death in men and women, and is responsible for 1.3 million deaths worldwide annually, as of 2004 (37). The main types of lung cancer are small cell lung carcinoma (SCLC) and non-small cell lung carcinoma (NSCLC)....   [tags: carcinoma, tobacco, treatment]

- Gene Doping is the practice of using gene therapy to improve athletic ability by altering the effectively of genes utilized in athleticism. Gene Doping is defined as “the non-therapeutic use of cells, genes, genetic elements, or of the modulation of gene expression, having the capacity to improve athletic performance." (Light). Gene Doping is considered highly illegal in most sports even though there has never been any known incident of an athlete using it. There are two kinds of gene doping: Somatic gene doping and Germline gene doping....   [tags: athletic ability, athletic performance]

Cystic Fibrosis : Regulator Gene ( Ctfr ) Essay

- Cystic fibrosis (CF) is a generated from a defect in the cystic fibrosis transmembrane regulator gene (CTFR). A typical individual with a functioning CTFR gene will produce a thin and lubricating mucous, but with a defective gene the individual produces a mucus that is thick and viscous. Organs that rely heavily on secretions of mucus are the lungs, pancreas, and intestines. A person with CF though has trouble with the thickness of the mucus and these organs struggle to function properly. The airways in a normal lung have a light coating of mucus, whereas a person with CF has thick and sticky mucus lining the airway....   [tags: PH, Carbon dioxide, Acid, Bicarbonate]

Gene Therapy Essay

- Gene Therapy In the middle of the 19th cent, Gregor Mendel performed his landmark experiments indicating that certain traits can be inherited and he proposed a discrete unit of inheritance that we now call a gene. Since then scientists have come to appreciate the gene and have focused on the link between genes and diseases. Gene Therapy is a young and experimental procedure with goals to ultimately prevent diseases by changing the expression of a persons genes. However, there are factors that prevent the absolute success of this procedure, but scientists are continuing to work to find cures for genetic disorders and with technology improving will eventual have absolute success....   [tags: Papers]
