Transfusion reaction

blood transfusion and other healthcare procedures when the need arise. Statistics according to the (American Journal of Medicine n.d.) “About 900 Jehovah’s Witnesses die each year because of the blood refusal policy.” It also emphasizes the fact that everytime a JW has “bloodless surgery” his or her chances of dying is 1% greater. Research According to the American Association of Blood Banks…

Sickle cell anemia is an inherited form of anemia where an individual has either a lack of red blood cell or dysfunctional blood cell, resulting in a lack of oxygen and nutrients to the cells. Normally, a red blood cell would be round, flexible, and flat in the center to allow easy passage in the blood vessels. However, the individual with sickle cell anemia will have cells that are rigid, sticky, and shaped like a crescent or sickle which is where the name comes from. Because of its unique…

In David Cyranoski’s article from 29th September, 2015 on Nature.com website , he mentioned that a famous genomics institute in Shenzhen is going to sell gene-edited miropigs as pets, and each costs $10,000 yuan (US$1,600). The customers can choose unequal coat colours and patterns of pigs through their gene arrangement subsequently. Those pigs not only can be our pets, but also were fabricated as models for human disease by using a gene-editing tool --- TALENs. Geneticists make use of TALENs to…

Afghanistan: There were many challenges in the military but I am choosing to write about one scenario that made me realize what type of person I am. Even though I had struggle all through school, I was surprisingly good at being a Marine. Once I finished my first year in the military my parents grew to be pretty comfortable with the idea of me being in the corps. I think it is because they saw that I was finally growing up. In the Marine Corps they do not care about excuses and they definitely…

electrophoresis and reaction enzymes and then comparing them to the DNA found at a “crime scene” to detect a match. After the experiment was complete the Materials & Methods Part 1 To begin this part of the experiment there needs to be a couple of reaction tubes labeled 1 through 4. First 10 microliters of reaction buffer to reaction tubes 1 and 2. You will then need to add 15 microliters of suspect 1’s DNA to both tubes (1 and 2). After that add 15 microliters of reaction enzyme 1 to…

(a) Roughly from 25% - 120% (b) Mild hemophilia: 5% - 15% Severe hemophilia: demonstrating less than 1% of normal activity. 11. The qualitative function is affected therefore it could be due to heparin therapy, massive transfusion or vitamin k deficiency. 12. Clinical presentation would be the same. It forms clot, however there bleeding time would be abnormal. 13. (a) Hereditary factor deficiency- affects only a single factor Acquired deficiency- caused by multiple…

Human factors to be considered include ergonomics, fit, ground reaction force, weight, durability, stability, and cushioning. Ergonomics dictates good posture. In order to maintain good posture, referred to as 'neutral posture ', the muscles of the body must be in balance to support an aligned spine13. The design of this shoe must take ergonomics, perception, quality control, and biomechanics into account. Fashion has been a deciding factor in the shoe industry over the last decade.14 For…

Dissolving can be either endothermic or exothermic. Endothermic reactions happen when the energy given out when bonds are broken, is greater than the energy given out when bonds are made. As more energy is used and taken in, the surroundings become colder. Dissolving is exothermic when energy is given out to its surroundings. In an exothermic reaction bonds are being made. The energy is usually transferred as heat energy, causing the reaction mixture and its surroundings to get warmer.…

Enzymes speed up the rates of most biochemical reactions by helping reactants interact with each other. Since enzymes are highly specific for a specific reaction, they only catalyze one or a few types of reaction. One of important enzymes in human body and many other animals is amylase that hydrolyzes starch, a major part of human diet for many people in the world. There is a variety…

Concentration on Reaction Rates and Pressure Background - While conducting the Enzyme Lab, students used enzymes as catalysts in order to speed up the reaction processes involved in several tests. Enzymes are substances produced by living organisms that act as a catalyst, while a catalyst is a substance that increases the rate of the chemical reaction. Furthermore, varying amounts of pH and enzymes were added to the mixture in order to determine the substance’s rate of reaction. When the…
