avoiding malaria‚ this mutation can also lead to sickle cell anemia. Sickle cell specialist Dr. Ronald Nagel stresses the genetic variety necessary for the existence of a species. A gene known as HbS was the center of a medical detective story that began in the middle 1940s in Africa. Doctors noticed that patients who had sickle cell anemia‚ a serious inherited blood disease‚ were more likely to survive malaria. What was confusing was why sickle cell anemia was so dominant in some African populations

Amy‚ Marcus and Richard have all been diagnosed with a blood disorder where treatments are available. There is information provided for each disorders cause‚ the criteria for diagnosis‚ the treatment and how it can be prevented. When the body lacks adequate amounts of iron in the red blood cells’ hemoglobin you will find iron deficiency anemia. Hemoglobin is made from iron

Proteins have lively and complex structures. The purpose of a protein is decided by its structure; a change in the proteins activity level causes a change in some part of the proteins shape.

Sickle Cell Anemia INTRODUCTION: “Pain” sudden or chronic‚ lasting from a few hours to a few days; from a few weeks to a few months evolving from an adhesive substance in red blood cells. The “Pain” is inherited by an retriction blood flow through the body do to an abnormality in the cells. “Sickle Cell Anemia” a chronic illness discovered in 1910 by an American physician named James Bryan Herrick. Sickle Cell is more that just pain; it is a disease that is affected by abnormal blood cells that

Anemia: People with anemia have a low number of red blood cells. Mild anemia often causes no symptoms. More severe anemia can cause fatigue‚ pale skin‚ and shortness of breath with exertion.
