Sickle cell disease (SCD) is a group of inherited conditions that affect the red blood cells. People affected with sickle cell disease produce abnormally shaped red blood cells that causes health problems. Sickle cell disease is caused by a defective gene passed on from the parent to the child. Sickle cell disease is condition that is considered serious and lifelong. People of African descent are mainly affected with sickle cell disease in addition to ‚ Caribbean‚ Middle Eastern‚ Eastern Mediterranean

Structure of the Stem The internal structure of the stem is usually more complex than the other plant organs for it performs and provides various functions. These functions are: * For mechanical support * For conduction of water * For conduction and storage of manufactured food * For continuous growth of the stem in thickness These functions are centered at the fibro vascular system that is composed of two major tissues‚ the xylem and the phloem. Internal Parts of Woody Stems 1. Protective

after the conclusion of therapy. The couple stated that they felt they were much better with cooperation and understanding‚ but remained worried about family issues and acceptance. The couple stated that they were still struggling with issues of autonomy vs. togetherness; “me problems versus we problems.” The couple also presented with concerns about the strength of their current support system.

Analysis of STEM fields Analysis of STEM fields 1. Introduction STEM is an acronym that referring to Science‚ Technology‚ Engineering‚ and Mathematics (Rotherham‚ 2011). What is STEM? The simple answer is that STEM means jobs. A complicated answer is that it is an educational key to a better U.S. economy; it addresses the growing disconnect between the skills that employers need in a rapidly increasing technological world and the lack of talent that the education

with a history of the autosomal recessive disease Sickle cell anaemia should have all embryos screened with Pre-Implantation Genetic Diagnosis technology (PGD). If tested positive‚ treatment should be made compulsory for the child at a young age and will be treated with stem cell gene therapy. This disease has no personal relevance to me‚ however‚ there is currently 90K people suffering from Sickle cell anaemia in the United States. Sickle cell anaemia is relevant to society because it greatly reduces

What is the function of non-coding DNA besides structural? There has been speculation about Non-coding’s function. Non-coding DNA has been said to be “Junk DNA” until scientists have found evidence for it having a structural function. More scientists are now trying to find more functions that Non-coding DNA might have. Non-coding DNA lies between genes on the Chromosome and does not code for amino acids. Regular DNA is also found in the Chromosome‚ but it does code for amino acids with help from

Sickle Cell Anemia Sickle Cell Anemia is a blood disorder that shortens the life span of red blood cells‚ and eventually the organisms they are located in. Sickle Cell Anemia is an inherited blood disorder that changes that structure of red blood cells. In a healthy organism‚ red blood cells are disk shaped and move easily through the blood vessels. In an organism that has sickle cell anemia the red blood cells’ structures are corrupted; instead of the disk-like shape‚ the red blood cells have a

Follicle Stem Cell Niche and the Function of the Rac1 protein within the niche. Abstract: An adult stem cell’s niche is responsible for the preservation of the stem cell’s undifferentiated state through either intrinsic or extrinsic expression of specific proteins (Scadden‚ 2006). Situated in the bulge of the hair follicle‚ hair follicle stem cells (HFSC) are quiescent in nature and are responsible for not only its self renewal but also in the production of rapidly proliferating cells. These cells
