  • Contrast To The Host Cell
    499 words
    Why are Viruses considered an exception to the Cell Theory Viruses are prolific. They have been found in almost all parts of the Earth, including the Arctic. They infect nearly every form of life from the simplest unicellular organism (bacteria) to complex mammals, such as humans. The structures of all human viruses have several common attributes. First is their incredibly small scale. There are 10 x 10+9 nanometers in a meter. Viruses are so minuscule that they can only be visualized using elec...
  • Usefulness Of Human Embryonic Stem Cells
    4,180 words
    Few recent scientific issues have stimulated so much media attention, public debate and government involvement as that of stem cell research. Stem cells offer people hope by promising to greatly extend the number and range of patients who could benefit from transplants, and to provide novel therapies to treat debilitating diseases such as diabetes, Parkinson's, Huntington's, heart disease and stroke, as well as accidental damage such as spinal cord injury. So why would anyone object to research ...

  • Adult And Embryonic Stem Cells
    1,178 words
    Stem cells relate to the person health of an individual. Stem cells have the remarkable ability to develop into many different cell types in the body. Able to be a repair system for the body, they can divide without limit to replenish other cells as long as the person alive and able to provide nutrients to the cells. When a stem cell divides, each new cell has the potential to either remain a stem cell or become another type of cell, such as a muscle cell, a red blood cell, or a brain cell. Stem...

    1,483 words
    Oh the Healing Possibilities What if Superman was able to walk again? Christopher Reeves was the actor we all knew as Superman. A few years ago he had a horse-back riding accident which left him paralyzed from the neck down. His spinal cord was severed and there was nothing doctors could do to help him but, there might be hope for him after all. There is a great new field of research in which scientists are trying to find ways to solve these types of problems along with many others. Research in ...
  • 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 ...
