|Sickle Cell Anemia||
An inherited red blood cell (RBC) disorder and one of the group of disorders of Sickle Cell Disease. In Sickle Cell Anemia, RBCs assume a sickle, or crescent shape, and degrade prematurely, causing a lack of red blood cells (anemia) to perform gas exchange. Shortness of breath, fatigue, and delayed growth and development in children are common conditions.
|Red Blood Cells (RBCs), Sickle Cell Disease|
|Sickle Cell Disease||
A group of inherited red blood cell disorders caused by the production of hemoglobin S, a protein in red blood cells (RBCs) that causes RBCs to assume a sickle, or crescent, shape. Sickled red blood cells break down prematurely, which causes the group of disorders, including Sickle Cell Anemia (a lack of red blood cells causing shortness of breath, fatigue, and delayed growth and development in children), jaundice (yellowing of the eyes and skin due to rapid breakdown of red blood cells), clotting (sickled red blood cells, which are stiff and inflexible, get stuck in small blood vessels depriving tissues and organs of oxygen-rich blood and can lead to organ damage, especially in the lungs, kidneys, spleen, and brain), and pulmonary hypertension (high blood pressure in the blood vessels that supply the lungs). Repeated infections, and periodic episodes of pain are also common. The severity of symptoms varies from person to person.
|Clotting (Blood), Hemoglobin S, Infection, Jaundice, Proteins, Pulmonary Hypertension, Red Blood Cells (RBCs), Sickle Cell Anemia|
|Sickle Cell Trait||
In humans, a condition in which a person is heterozygous for codominant alleles of the hemoglobin subunit beta (HBB) gene and produces both normal hemoglobin proteins (hgb) and abnormal hemoglobin proteins (hemoglobin S, which causes red blood cells (RBCs) to assume a sickle, or crescent, shape). In environments where malaria is endemic, humans with Sickle Cell Trait have a selective advantage as it confers some resistance to malaria. Sickle cells prevent the malaria parasite from stealing actin (a protein that maintains the pliable internal skeleton of RBCs). Actin is used by the parasite to transport another protein, adhesin (produced by the parasite), to the cell surface. Adhesin causes the infected red blood cells to adhere to each other and to vessel walls, resulting in microvascular inflammation. A person with Sickle Cell Trait does not display the severe symptoms of Sickle Cell Disease.

A process where an individual takes cues from other people in the environment, about which emotions and actions are appropriate in a certain context or situation.
The experience, expression, and management of emotions and the ability to establish positive and rewarding relationships with others. It encompasses both intra- and interpersonal processes. The core features of emotional development include the ability to identify and understand one’s own feelings, to accurately read and comprehend emotional states in others, to manage strong emotions and their expression in a constructive manner, to regulate one’s own behavior, to develop empathy for others, and to establish and maintain relationships.
