Introduction - sickle cell anemia The first suggestion that genes might provide the information for all proteins came from Linus Pauling’s lab at Caltech. He and his student Harvey Itano studied hemoglobin‚ the protein in red blood cells that transports oxygen from the lung to metabolically active tissues‚ like muscle‚ where it is needed. In particular‚ they focused on the hemoglobin of people with sickle-cell disease‚ also known as sickle-cell anemia‚ a genetic disorder common in Africans‚ and

Adams 1 Dwayne Adams Instructor: Croshaw Medical Terminology 1 18‚ April 2013 Sickle Cell Anemia Sickle-cell Anemia is a genetic blood disorder caused by the presence of an abnormal form of hemoglobin molecules in which the red blood cells loose their disc-shape and become crescent shaped. The shape also known as “hemoglobin S”. unlike normal red cells which are usually smooth and malleable‚ tend to collect after releasing oxygen‚ and cannot squeeze through small blood vessels. The

Sickle cell anemia is a genetic disease that affects the shape and functionality of red blood cells. It is caused by a mutation in the DNA of the protein‚ hemoglobin‚ specifically in the beta chain. There are 531 base pairs in this DNA strand. Substitution or point mutation occurs‚ causing “GAG” to become “GTG”. This results in valine being created instead of glutamate. The mutation causes the hemoglobin to cling together in low oxygen levels and the red blood cell changes shape‚ preventing it from

Sickle Cell Anemia first came into the view of the world around 1910 when Dr. James Herrick; a cardiologist‚ had a patient who complained of pain and described symptoms that sounded like anemia. He handed the case down to his assistant who‚ after taking a blood sample‚ discovered that the patient’s blood cells were not shaped like normal blood cells. When the patient’s blood cells were compared to normal blood cells‚ they appeared to be “sickle shaped”. After seeing this for himself Dr. Herrick took

Background One of the most extensive nutritional deficiencies is iron deficiency. Globally >2 billion people are suffering from iron-deficiency anemia. Iron is the mineral found in every cell of the human body. [1] During blood loss‚ inadequate iron intake‚ pregnancy and poor absorption of iron the human body suffers a condition called iron deficiency anemia. According to the Office of Dietary Supplements it is declared that iron needs vary by gender and by age. Infants need atleast 11mg/day while
