Description

Hemophillia is a rare bleeding disorder in which the blood does not clot normally. Hemophillia is usually inherited and people born with it have little or no clotting factor (a protein needed for normal blood clotting). These proteins work together with platelets to help the blood clot. When blood vessels are injured, clotting factors help platelets stick together to plug cuts and breaks on the vessels. Hemophillia usually occurs in males with about 1 in every 5 000 males being born with the disease each year. A hemophiliac does not bleed more intensely than a person without it but can bleed for a much longer time. In some severe cases, continuous bleeding occurs after minor trauma or can even happen spontaneously.They may also bleed inside their body(internally), especially in the knees, ankles, and elbows. The bleeding can damage organs and tissues and may be life threatening. There are two main types of hemophilia: A and B. People born with type A are missing or have low levels of clotting factor VIII (1 in 5 000 males). People born with type B are missing or have low levels of clotting factor IX (1 in 20 000 males). About 8 out of 10 people who have hemophillia have type A. The greatest concern for both types is deep internal bleeding and bleeding into joints. Hemophilia is a life long disease, but with proper treatment and self-care, most people maintain an active productive lifestyle.

Causes

Hemophillia is caused by a defect in one of the genes that determines how the body makes blood clotting factor VIII or IX. These genes are located on the X chromosomes. Females have two X chromosomes, while males have one X and one Y. Only the X chromosome carries the genes related to clotting factors. A male who has...

    Sex-linked disorders only affect males and are passed down through female carriers. A boy inherits the disorder when he receives an X chromosome with a mutated dystrophin gene (the genetic cause) from his mother. The dystrophin gene is the largest gene found in nature and was identified through a positional cloning approach. It's a highly complex gene, a large rod-like cytoskeletal protein which is found at the inner surface of muscle fibers. (www.ncbi.nlm.nih.gov)

  • Analysis Of Bad Blood: A Cautionary Tale

    Many people throughout the world visit the United States every year to receive medical treatment. This is due to our excellent pharmaceutical industry as it spends million of dollars and many hours of research to come up with what we can only describe as “miracle” drugs and treatments. Part of the success of many of these medications is because the pharmaceutical industry is highly regulated by policies that protect the public from accessing drugs that have not been fully tested and found to be “safe”. However, this was not the case until the late 1990s and early 2000s. One time in history that highly influenced the strict regulations we currently have was the nationwide contamination of patients through blood transfusion or by consuming medications

    About eighty percent of all cases of hemophilia have an identifiable family history of the disease; in other instances, it may be attributable to a spontaneous mutation. Researchers recently discovered that the spontaneous mutation of the factor VIII gene in two children was due to the attachment of a foreign "jumping gene" that disrupted the blood-clotting ability of the factor VIII gene. Inheritance is controlled by a recessive sex-linked factor carried by the mother on the X chromosome. A probability of one in two exists that each boy born to a normal male and a carrier female will be hemophiliac and the same chance that each girl of this union will be a carrier.

    Hemophilia is a genetic disorder in which the blood does not clot normally. It’s a rare bleeding disorder that has been happening since ancient times. Men are the ones mainly affected by it. One in five thousand men born each year have Hemophilia. Yet women can be carriers and just like men, they can suffer from symptoms too. Women can only have Hemophilia if their father does and mother is a carrier, it’s uncommon but can happen. Hemophilia affects all races and ethnic groups. It’s all based on your family tree. A man with Hemophilia will pass the gene down to his daughters, leading to them becoming carriers. A woman with the gene has a fifty percent chance of passing the gene down on to her sons. If there was no family history of Hemophilia but the woman is a carrier, a son could possibly be the first one in the family to have it. If there’s one thing for certain about hemophilia is that it does not discriminate against anyone. Hemophilia has affected royalty as well as high and low class men all throughout history.

    Hemophilia is a rare genetic blood clotting disorder that primarily affects males. People living with hemophilia do not have enough of, or are missing, one of the blood clotting proteins naturally found in blood. Two of the most common forms of hemophilia are A and B. In persons with hemophilia A (also called classic hemophilia), clotting factor VIII is not present in sufficient amounts or is absent. In persons with hemophilia B (also called Christmas disease), clotting factor IX is not present in sufficient amounts or is absent. People with hemophilia do not bleed more profusely or bleed faster than normal; they bleed for a longer period of time.

    Hemochromatosis is a disorder that can be inherited from your parents but can also be obtained due to excessive consumption of alcohol or iron or blood transfusions. Hemochromatosis is a disorder that causes your body to absorb more iron than it needs. It then stores the iron in crucial parts of your body like your heart, liver, pancreas, brain, and joints. If the iron continues to built it would lead to iron overload. Iron overload can be fatal because of excessive iron in your heart and liver. Continuous iron overload could lead to serious heart conditions like heart attack and heart failure, it could also lead to liver problems, diabetes mellitus, and possibly cancer and death. Symptoms like diabetes mellitus can be avoided if Hemochromatosis

  • Klinefelter Syndrome Analysis

    Klinefelter syndrome is a chromosomal abnormality that leads to alterations in the male phenotype. These alterations appear in both the physical and cognitive development ("Klinefelter syndrome - Genetics Home Reference", n.d.). Males affected by this disorder carry an extra X chromosome, which results in androgen deficiency, hypogonadism, and infertility (Smyth, 1998). Instead of being inherited, Klinefelter syndrome is due to spontaneous events during the formation of the parental germ cells. These events lead to an extra X chromosome in the cells of the offspring ("Klinefelter syndrome - Genetics Home Reference", n.d.).

Blood is extracellular matrix that is consists of plasma, red blood cells, platelets, and white blood cells. Blood is located within the capillaries/veins/arteries of the human body, which are blood vessels that run through the entire body. These blood vessels allow the blood to flow smoothly and quickly from the heart to distinct parts of the human body. The unique parts of human blood all work together for a purpose: the Red Blood Cells(erythrocytes) transports oxygen throughout the body, White Blood Cells(leukocytes) play a part in the bodies immune system, Platelets(thrombocytes) assist in creating scabs,
