  • People With Severe Sickle Cell Anemia
    1,165 words
    Sickle cell anemia is a hereditary disorder that mostly affects people of African ancestry, but also occurs in other ethnic groups, including people who are of Mediterranean and Middle Eastern descent. More than 70,000 Americans have sickle cell anemia. And about 2 million Americans - and one in 12 African Americans - have sickle cell trait (this means they carry one gene for the disease, but do not have the disease itself). Sickle cell anemia occurs when a person inherits two abnormal genes (on...
  • Ethics Of Stem Cell Research
    1,156 words
    Just about everyone in the world today knows either a loved one or a friend that is dying of a fatal disease or a terminal illness. Every day people are dying of incurable diseases due to the lack of knowledge or the lack of treatment for their disease. Imagine if there was a cure or an answer to save your loved ones or friends life, wouldn't you want to give them a second chance at living life? In the recent scientific world there has been research done on stem cells. Stem cells are specially g...
  • Vascular Endothelial Growth Factor With Endothelial Cell
    892 words
    PDF induces proliferation of fibroblasts, micro glia, and smooth muscle. It is stored in platelet granules and is released following platelet aggregation. PDGF may also serve as a chemo tactic agent for inflammatory cells. Platelets circulate in the blood and are derived from in the marrow. Like erythrocytes, they are a nucleate. However, unlike erythrocytes, they contain numerous intra cytoplasmic granules and are the source of numerous pro inflammatory mediators. In fact, they are quantitative...
  • Public Cord Blood Banking
    1,578 words
    INTRODUCTION A child is born everyday and without realizing it, the material that is routinely discarded after the birth could one day be life saving for that person, someone else in the family, or even a complete stranger. This material is the umbilical cord, and the blood contained within their vessels. One may wonder, why is this blood so important? Medical research has discovered that the residual umbilical cord blood contains stem cells. These cells are the building blocks that the body use...
  • Acute Leukemia Causes
    490 words
    Leukemia Leukemia is a disease that affects blood-forming tissues, mainly bone marrow. Leukemia also affects the lymph glands and spleen. Leukemia causes the body to produce an extreme amount of abnormal white blood cells. This causes infections because the abnormal cells cannot stop infections like the normal cells do. Leukemia also causes anemia. Anemia is a disease in which the body makes less blood cells. This happens because the leukemic cells crowd the system. Leukemia also causes excessiv...
  • Genetic Mutation In The Hemoglobin Gene
    809 words
    Charles Darwin stated that over time life could change so much so that new species are formed from a single species. But Darwin did not know where these mutations occurred. His theory could explain how humans and chimps are so alike yet different. Are we all just accidents of creation caused by mutations Genetic mutations occur in the DNA of an organism. They can be influenced by environment or may occur during mitosis or meiosis. Mutations have been shaping life since it began and is the cause ...
  • Blood Vessel
    502 words
    1) To overcome many of the obstacles on the path of any life function, specifically gas exchange, evolution has provided many adaptations. Some of these are the gills fish have developed, some insects ability to diffuse oxygen to individual cells or a moist diffusion barrier in humans. Fish have developed a trait called countercurrent exchange, in which blood passes through vessels in a direction opposite to that of water flowing over the gills of the fish. This allows the oxygen-rich water to f...
  • Most Primitive Types Of Leukemia Cells
    2,028 words
    Leukemia is a malignant disease of the bone marrow and blood. It is characterized by the uncontrolled growth of blood cells. The term leukemia has a Latin derivation. Leuk o means white and heme is blood. Therefore the word leukemia literally means white blood. The common types of leukemia are divided into four major categories: myelogenous and lymphocytic, which can then be divided into acute or chronic. Thus, the four major types of leukemia are acute or chronic myelogenous leukemia and acute ...
  • Patient's Own Cord Blood In Some Cases
    1,353 words
    Should parents pay a blood bank to store the blood from their newborn baby's umbilical cord and placenta, in case that child or another family member ever needs it to treat cancer or leukemia Expectant parents are being urged to do so by companies that have sprung up during the past few years to sell cord-blood banking as a form of "biological insurance" against such dreaded diseases. The pitch is based on reports in medical journals, such as a major study published last week in the New England ...
  • Less Common Form Of Sickle Cell Disease
    1,735 words
    Sickle cell disease is not contagious. It is a genetically inherited disease that affects the red blood cells. Normal red blood cells are round, but sickled red blood cells are crescent shaped. There are many people living with sickle cell, but it can be fatal. Usually people with the disease die between the ages of 20 and 40 due to organ complications. Red blood cells contain a special protein called hemoglobin (Hb) that carries oxygen from the lungs to all parts of the body. Hemoglobin is prod...

    Respiratory system-gets oxygen to cells of your body and getting rid of carbon dioxide and breathing; involves the formation of ATP within cells; made up of nasal cavity, pharynx, larynx, trachea, bronchi and bronchioles, and lung Path of air-taking in air through nose or mouth; flows into pharynx; passes the epiglottis; moves through larynx; goes down windpipe trachea; bronchi; lead into lungs Trachea-tube like passageway that leads to two bronchi tubes; windpipe Epiglottis-piece of skin covers...
  • Stem Cells From Other Cells In Blood
    1,206 words
    Stem Cell Research Miguel Amador Biology 131 November 8, 2003 Stem Cell Research Stem cells are located deep down in our bone marrow. They have the incredible ability of "generating an endless supply of red cells, white cells, and platelets" (1). They have been called the "Mother of all blood cells" due to their ability to regenerate the entire blood supply of a persons body. Just to think that this is possible is actually pretty incredible. The man who claims to be responsible for the discovery...
  • Sickle Cell Disease
    1,054 words
    Cystic Fibrosis is a disorder where the exocrine glands secrete abnormally thick mucus, leading to obstruction of the pancreas and chronic infections of the lungs, which usually cause death in childhood or early adulthood. Some mildly affected patients may survive longer. Doctors can diagnose the disease by testing the patients perspiration because people with Cystic Fibrosis have high amounts of salt in their perspiration. Those with respiratory infections are treated with antibiotics, with aer...
  • Hiperkrom Anemia The Red Blood Cells
    863 words
    Anemia is an illness all over the world. Anemia has many types but some kinds of this illness can be cured while some not. Anemia is an illness caused by the lack of hemoglobin or the red blood cells. Anemia can be classified into three main categories: hipokrom anemia, hiperkrom anemia and normokrom anemia. These three kinds of anemia are caused by different kinds of deficient cells. Today the reseaches done on anemia shows that there are new kinds of cures for this illness. In this report anem...
  • Regulation Of Erythropoietin Production
    1,091 words
    Introduction. Erythropoietin is a glycoprotein that is produced primarily in the kidneys in adults and, to a lesser extent, in the liver. It behaves like a hormone, regulating the level of erythropoiesis, and keeping the RBC count within a narrow range It is used widely in medicine as a treatment for a number of serious illnesses, ranging from types of anaemia, to the treatment of certain types of cancer, and also in the battle against AIDS. Unfortunately certain athletes, who will do anything t...
  • Normal Range For Neutrophil Count
    2,593 words
    Leukocytes and the leukocyte differential count To consider the leukocytes together as a group is something of a granfalloon, because each type of leukocyte has its own function and ontogeny semi-independent of the others. To measure the total leukocyte count and allow this term to mean anything to the doctor is a travesty, yet the "wbc" count has traditionally been considered a cardinal measurement in a routine laboratory workup for just about any condition. I cannot emphasize too much that to ...
  • Dominant Q 6 What 2 Gene Combinations
    716 words
    Short notes: 1.) Cystic Fibrosis: Abbreviated as CF and also called mucoviscidosis. It is a common hereditary disease in which cells of certain glands in the body secrete large amounts of abnormally thick mucus. Accumulation of thick mucus can block products of these glands and eventually block passage of seaways of organs into which the ducts empty. Symptoms are constant cough, which expels thick mucus, etc. Lung problems are most common cause of death for cystic fibrosis patients. CF can be di...
  • Effects Of Sickle Cell Anemia
    552 words
    Sickle Cell Anemia I did research on Sickle Cell Anemia; it affects about 72,000 Americans in the United States. Sickle cell anemia is an inherited disease in which the body is unable to produce normal hemoglobin, an iron-containing protein. Abnormal hemoglobin can morph cells that can become lodged in narrow blood vessels, blocking oxygen from reaching organs and tissues. The effects of sickle cell anemia are bouts of extreme pain, infectious, fever, jaundice, stroke, slow growth, and organ fai...
  • Hemoglobin Level And Red Blood Cell Count
    795 words
    Each year athlete's abilities to perform and exceed beyond previous year's seems to increase. Better training methods, better conditioning techniques, and better overall health of the athlete can contribute to this increased ability. However, "some athletes always seem to take it a step further. They engage in a process called blood doping". (Beckham, 2002, ). Blood doping, also called induced erythrocythemia, is an intravenous infusion of blood that produces an increase in the blood's oxygen ca...
  • Cell Mass Of 2 Millimeters In Diameter
    507 words
    Cells inside of our body are under strict genetic control. If the genes controlling our cells become mutated, the cells can become disorganized by losing their function and dividing abnormally at less restraint than their neighboring normal cells. This activity causes the cells to fail to fully mature. Within our cells, we have regulatory proteins that perform such functions as correcting damaged genes. Other proteins indicate to a cell that division must cease so it can mature. A mutation of th...
