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

* Potassium chloride administered intravenously must always be diluted in IV fluid and infused via a pump or controller. The usual concentration of IV potassium chloride is 20 to 40 mEq/L. Potassium chloride is never given by bolus (IV push). Giving potassium chloride by IV push can result in cardiac arrest. Dilution in normal saline is recommended‚ but dextrose solution is avoided because this type of solution increases intracellular potassium shifting. The IV bag containing the potassium chloride

Acute Chest Syndrome And Sickle Cell Disease In The Pediatric Patient. Sickle Cell Disease: Is a generic disease that affects hemoglobin‚ oxygen transport in the body and patient quality of life. This disease is most common in African American‚ Hispanic‚ Greek and Arabs. Note: Sickle Cell is inherited from both parents. Sickle cell is a blood disease in wish the red blood cells that are responsible for carry oxygen from the lungs to other part of the body are behaving in an abnormal way because

Infectious mononucleosis is caused by the Epstein-Barr virus (EBV). It is a double stranded DNA virus indistinguishable from other members of the herpes virus group. It get its’ name from the mononuclear (single nucleus) cells. It is also known as the "kissing disease"‚ because the most frequent mode of transmission is intimate salivary contact. It can also be transmitted from shared drinking and eating utensils‚ toothbrushes‚ etc. Mono is not likely to spread by aerosol (ex. sneezing) or fomites

The chemotherapy treatment‚ causes a variety of side effects. One of the adverse effect is called as myelosuppression‚ where the bone marrow activity is decreased resulting in fewer red blood cells‚ white blood cells‚ and platelets (National Cancer Institute [NIH]‚ n.d.). The normal hematological lab values for a 13 year old

realize that they are suffering from it. It can be only analyzed by the blood test in form anemia. Symptoms of thalasemia are fatigue‚ pale skin‚ protruding abdomen‚ dark urine‚ and abnormal facial bones. The symptoms depend on the type and severity of the disease. These kinds of symptoms typically occur when oxygen is not able to pass in various parts of the body due to low hemoglobin and a shortage of red blood cells in the blood. People with alpha thalassemia trait or beta thalassemia trait usually

Histology Introduction Histology is the microscopic study of cells and tissues of organisms. This study is important in the overall understanding of anatomy and physiology of organisms. It helps to understand the structures and functions of various tissues that make up bodily organs and systems (Wendy Wright‚ 2014). The cell theory states that a cell is the fundamental biological unit. All living organisms are composed of one or more cells‚ and every bodily activity that takes place in a living organism

You must understand the concepts of dominance and how this plays a role in monohybrid crosses (mono = one = one characteristic or trait). Be aware of confusing the word ‘cross/ crossing’ with ‘crossing

ABSTRACT: The Erythrocyte Sedimentation Rate (ESR)‚ also branded as sedimentation rate or Biernacki Reaction‚ is the rate at which red blood cells sediment in a time of 1 hour. To execute the test‚ anti-coagulated blood is positioned in an erect tube‚ known as a Westergren tube‚ and the rate at which the red blood cells fall is calculated and accounted in millimeters per hour (mm/h). The erythrocyte sedimentation rate (ESR) is rarely the solitary
