  • The Effect of Nonsteroidal Anti-Inflammatory Drugs on Chick Embryo Fibroblast Cells and Its Relation to Colon Carcinogenesis

    The Effect of Nonsteroidal Anti-Inflammatory Drugs on Chick Embryo Fibroblast Cells and Its Relation to Colon Carcinogenesis

    The Effect of Nonsteroidal anti-inflammatory drugs on chick embryo fibroblast cells and its relation to colon carcinogenesis Abstract NSAID's are chemopreventive mediators of colon carcinogenesis, although their molecular pathway is unknown. Previous studies suggest that NSAID's best known effect is its inhibition of prostaglandin, a lipid that is derived from fatty acids. To study the effect of NSAID's on chick fibroblast cells, we sought to apply aspirin (a common NSAID) to these cells in

    Whether or Not Cell Phones Should Be Allowed on School Campus

    Whether or not cell phones should be allowed on school campus Many children today own a cell phone and usually bring it to school. However, a plethora of people who work at the school don’t like the idea of having cell phones on school campus for countless of reasons. So now there is this big controversy on whether or not cell phones should be allowed on campus. In spite of this I believe that children

  • Sickle Cell Anemia

    Sickle Cell Anemia

    Sickle Cell anemia is a group of inherited red blood cell disorders, or a collection of recessive genetic disorders characterized by a hemoglobin variant called Hb S. Normal red blood cells are round like doughnuts, and they move through small blood tubes in the body to deliver oxygen. Sickle red blood cells become hard, sticky and shaped like sickles used to cut wheat. When these hard and pointed red cells go through the small

    Stem Cell Essay

    One of the greatest issues in the world today is the threat of neurodegenerative diseases. These diseases are responsible for about 60,000 deaths per year, many of which are preceded by up to several years of excruciating pain and suffering. These, among other health issues such as heart disease, arthritis, and diabetes, are treatable with stem cell therapy. With the myriad of diseases treatable with stem cell technology, it is surprising that more effort is

  • Sickle Cell Anemia

    Sickle Cell Anemia

    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

    When a cell phone goes off in a classroom or at a concert, people are irritated, but at least lives are not endangered. When on the road, however, irresponsible cell phone users are more than irritating: They are putting our lives at risk. Many of us have witnessed drivers so distracted by dialing and chatting that they resemble drunk drivers, weaving between lanes, for example, or nearly running down pedestrians in crosswalks.

    The Cell as the Basic Unit of Life

    Like cement sets the foundation for a house, the cell theory sets the foundation for biology. Schleiden and Schwann proposed the cell theory, which states that the cell is the basic unit of life and that new cells arise only from the reproduction of already existing cells via cell cycle, in 1839. Since the cell is the structural and functional unit of life as the house is for a community, without the house the community

    Sickle Cell Anemia Sickle cell anemia is an inherited blood disorder, characterized primarily by chronic anemia and periodic episodes of pain. The underlying problem involves hemoglobin, a component of the red cells in the blood. The hemoglobin molecules in each red blood cell carry oxygen from the lungs to the body organs and tissues and bring back carbon dioxide to the lungs. In sickle cell anemia, the hemoglobin is defective. After the hemoglobin molecules give

  • Drug Resistance Mechanisms in Cancer Cells

    Drug Resistance Mechanisms in Cancer Cells

    INTRODUCTION A major obstacle in the successful treatment of cancer is the development of resistance mechanisms to drug treatment. Various cellular changes that have been implicated in the development of drug resistance in cancer cells include: the increased expressions of P-glycoprotein (a multidrug transport protein) and multidrug resistance-associated protein (MRP-1); increased levels of the cellular detoxification protein, glutathione; and changes in the expression of apoptosis associated proteins such as Bcl-2, FasL and p53, which generally
