Chemistry Link To Health: Blood Types and Carbohydrates
According to Karen C. Timberlake, “every individual’s blood can be typed as one of four blood groups” (556). The differences in blood is what makes every human body different from the next. Studies have shown that “people have either blood group A, B, AB, or O, with each type occurring at different frequencies in populations around the world” (Ananthaswamy 15). An individual with one type of blood cannot share blood or organs with an individual of a different blood type. Failure to distinguish different blood types can cause reject when a patient receives the wrong type from a donor. Certain methods are used in determining what type of blood a patient has. However, there are certain blood types that can accept any type of blood, and there are also blood types that can be used for any type of patient. There are many different characteristics used for categorizing blood, such as blood types, agglutination, carbohydrates, antigens and antibodies.
Blood types can be categorized in many different ways. Karl Landsteiner categorized “the first three blood groups…[as] A, B and C (subsequently renamed O from the German word “ohne” which means “without”)” (Franchini 1545). Each of these blood groups also have unique properties that give the blood an inability to mix with other blood types. For example, Landsteiner has found out that type-A red blood cells contains an A-antigen and anti-B in its serum (Franchini 1545). Type A blood contains the monosaccharides N-acetylglucosamine, galactose, fructose, and “a N-acetylgalactosamine attached to galactose” (Timberlake 556).The A-antigen is used as an identifier for the body to determine whether something in the bodies system belongs or ...

Blood types, agglutination, carbohydrates, antigens and antibodies are all used to classify blood in health situations. There are four different types of blood types; type A, type B, type AB, and type O blood. Each of these blood types have specific antigen markers used for identification purposes, except type O, which contains no antigens. They also include antibodies that attack foreign invaders, except type AB, which contains no antibodies. The monosaccharide of each blood cell contains N-acetylglucosamine, galactose, and fructose. Type A, type B, and type AB has additional monosaccharides that differentiates itself from other blood types. Blood types can be determined by using the slide test method or test tube method, in which medical practitioners add antiserums and look for agglutination.
In Blood In Blood Out is a drama directed by Taylor Hackford, and starring Damian Chapa (Miklo), Benjamin Bratt (Paco), and Jesse Borrego (Cruz), produced by Hollywood Pictures. The film was based off everyday life in East Los Angeles, from the 1970’s through the 1980’s. Damian Chapa stars as Miklo in the film, a Mexican-American who wanted to be accepted, not by his skin but for the Mexican within him. Benjamin Bratt (Paco) was the older cousin of Miklo, who learned his lesson throughout the movie and changed his ways. Jesse Borrego (Cruz) is the step-brother of Paco who was a talent artist, who ended up turning to drugs because of back problems caused by a rival gang incident.
Three hundred and thirty-four years later in the future, Carl Landsteiner, a Viennese doctor, performed a very simple experiment with blood in 1901. During his experiment, Landsteiner noticed "clotting in some samples of mixed blood and not others". (Tucker, 10) Landsteiner separated his samples into three groups: A, B, and C, according to how they clotted in his experiment. Today, the blood type C is known as type O blood. When Landsteiner was grouping these blood types, he happened to look over type AB. AB occurs in about 3 percent of the population. Later in 1907, two researchers, Jan Jansky in Czechoslovakia and William Lorenzo Moss in the United
There are different types of bloodstain patterns that give a sense of what happened at the scene. The idea is to get a sort of background story from the random blood distribution. The different types of blood can tell us the method an assailant used such as passive blood stains. These stains are made from the drops off a weapon due to gravity. For instance, if an attacker w...
Racism, a plague in our society that has infected our society, and still does today, has been rooted by the premise of Darwinian evolution. Racism existed long before Charles Darwin made his mark in history; however, in the book One Race One Blood, the authors explain how there is a very close relationship between the theory of evolution and what we know today as racism. The authors intent of this book is to realize the effects of a specific ideas that has shaped racism. Mr. Ken Ham describes ideas as being seeds, “…they might seem small; they might seem insignificant; they might even go unnoticed by all expect those who hold them in the moment…” (7). Charles Darwin’s idea (or seeds) of his evolutionary has taken root and made its way into public schools, the government, and even our churches. Although, racism did not originate with Darwin, Ken Ham claims that, “he did more than any other person to popularize it” (22). His evolutionary ideas have fueled racism and this is what racists use to justify their hatred toward those who are different from them (8).
In the essay “Mixed-Blood Stew”, Jewell Parker Rhodes describes her mixed colored lineage and the penetrable makeup of all people along the color line. Rhodes recounts her childhood and shows how her family acknowledge each other of being more than just black and talk of all the race their blood consists of. She argues how people sees a black person; as black. She explains that black is not just black. Richard Rodriguez, author of “Blaxicans and Other Reinvented Americans” talks about how racial classifications, e.g. black, white, Hispanic, etc. should be discarded for they misrepresent the cultural and ethnic realities of today’s America (140). Rodriguez explains how culture has nothing to do with race and how certain labels (black, Hispanic)
Wallace Terry has collected a wide range of stories told by twenty black Vietnam veterans. The stories are varied based on each experience; from the horrific to the heart breaking and to the glorified image of Vietnam depicted by Hollywood. Wallace Terry does not insinuate his opinion into any of the stories so that the audience can feel as if they are having a conversation with the Vietnam Veteran himself. Terry introduces the purpose of the book by stating, “ Among the 20 men who portray their war and postwar experiences in this book. I sought a representative cross section of the black combat force.”(p. XV) Although the stories in this book were not told in any specific order, many themes became prominent throughout the novel such as religion, social, and health.
The primary method to control gestational diabetes mellitus (GDM) is through dietary regulation. The most effective method to control GDM via diet is through carbohydrate restriction and/or selectivity. It is recommended that pregnant women with GDM reduce their carbohydrate intake to 40% of the total caloric intake or can maintain a 60% carbohydrate intake but those carbohydrates must all come from low glycemic index foods. Examples of low glycemic foods are apples, spinach, black beans, split peas, oatmeal, and quinoa. Additional suggestions are to eat complex carbohydrates instead of simple, refined sugars. Eat small, frequent meals and snack often in between meals in order to maintain constant glucose levels throughout the day.
There are four different types of blood; A, B, AB, and O. This is called the ABO blood typing system. All four different types of blood serve the same purpose of transporting nutrients and oxygen throughout the human body. But what makes them different? Blood typing is based on the presence or absence of A and B cell antigens which trigger antibodies. Each kind of blood has it’s own antibody or immunoglobulin, which are proteins produced by the immune system to help stop intruders from invading your body. Therefore,
Although blood transfusions had been used before the First World War, many were not successful due to lack of knowledge in this type of treatments. World War I pushed the development of blood transfusions, allowing them to be safer. Before the war in the 17th century, blood transfusions often occurred with the use of animal blood, a practice that did not achieve desired results. These transfusions often times came from sheep, and although they were sometimes successful, it was discovered that any large amounts of transfusions would cause death. Coming to the conclusion that animal blood transfusions did not save lives, scientists looked to humans for human to human transfusions. Many of these attempted transfusions were met with failure but in 1818, Dr. James Blundell accomplished the first successful human blood transfusion; four ounces of blood were transferred to the patient from her husband. From that moment on, doctors began to learn even more about blood transfusions and how to do them properly. By 1901, the four human blood groups were discovered by Karl Landsteiner; with less differences in the bloods transfused together, coagulation and clumping amounts decreased. This benefited many lives in that toxic reactions to the wrong types of blood did not occu...
In this experiment, we determined the isotonic and hemolytic molar concentrations of non-penetrating moles for sheep red blood cells and measured the absorbance levels from each concentration. The results concluded that as the concentration increased the absorbance reading increased as well. A higher absorbance signifies higher amounts of intact RBCs. The isotonic molar concentration for NaCl and glucose is 0.3 M. The hemolysis molar concentration for NaCl and glucose is 0.05 M. Adding red blood cells to an isotonic solution, there will be no isotonic pressure and no net movement. The isotonic solution leaves the red blood cells intact. RBC contain hemoglobin which absorbs light, hemoglobin falls to the bottom of the tube and no light is absorbed. Determining the isotonic concentration of NaCl and glucose by finding the lowest molar concentration. In contrast to isotonic molar concentration, hemolysis can be determined by finding the
On the agarose plate, there should be a visible chalky white line. This line can vary depending on how the unknown sample interacted with the purified antibodies of the known. If there is a clean semicircular line that has no delineations at any of the wells then that means the unknown antibodies acted as an antigen. The smooth line tells us that all the antibodies interacted with the antigen equally and they would all be from the same species; this hopefully would not be the case. If the white chalky line is not smooth and extends more towards the human antibody wells, this means the unknown was a stronger antigen to the human antibodies than the rabbit antibodies making it not human blood at the scene. If the line is extended more at the rabbit antibodies or angles towards them, this signifies greater rabbit antibody interaction. This shows that the blood from the scene would not be rabbit blood because it caused the antibodies to be recognized as an antigen to the rabbit’s antibodies. These antibodies of the two species would then be classified as xenogeneic because the rabbit or human antibodies acted as an antigen to either of the known samples. Rabbit and human are not close in species, so that is why xenogeneicity can be concluded if these were the results.

After closely escaping an assassination and a kidnapping, Cardinal Bem finds himself a fugitive with enemies on every side. Terrorists, soldiers and even members of the proletariat will try and stop him at all costs. He will find his true friends and discover the ones who are simply out to get him.
Today, there are more advanced lab tests to help doctors classify ALL so they no longer have to rely on just the cell’s characteristics. These new lab tests aid in the grouping of ALL based on the type of lymphocyte the leukemia stems from (B cell or T cell) and how mature the cancer cells are (American Cancer Society, 2013)54.... ... middle of paper ... ...

I will be investigating Human Blood as my specific tissue and giving an overview on the location, characteristics, and the benefits it has to the human body. Blood is extracellular matrix that is consists of plasma, red blood cells, platelets, and white blood cells. Blood is located within the capillaries/veins/arteries of the human body, which are blood vessels that run through the entire body. These blood vessels allow the blood to flow smoothly and quickly from the heart to distinct parts of the human body. The unique parts of human blood all work together for a purpose: the Red Blood Cells(erythrocytes) transports oxygen throughout the body, White Blood Cells(leukocytes) play a part in the bodies immune system, Platelets(thrombocytes) assist in creating scabs,
It is easy to determine the blood group by determining the types of antigen on the surface of the red blood cell. The body will differentiate the own cells and foreign cell(potentially dangerous) with the aid of antigens. Blood group A has antigen A, blood group B has antigen B, blood group AB has both antigen A and antigen B, and the blood group O has no both antigens. If there is an antigen, there is an antibody.
