Critical review of haemolytic disease of the newborn Essay

Critical review of haemolytic disease of the newborn - Essay Example The mother's immune system sees the baby's Rh positive red blood cells as "foreign." Just as when bacteria invade the body, the immune system responds by developing antibodies to fight and destroy these foreign cells. The mother's immune system then keeps the antibodies in case the foreign cells appear again, even in a future pregnancy. The mother is now "Rh sensitized." In a first pregnancy, Rh sensitization is not likely. Usually it only becomes a problem in a future pregnancy with another Rh positive baby. During that pregnancy, the mother's antibodies cross the placenta to fight the Rh positive cells in the baby's body. As the antibodies destroy the red blood cells, the baby can become sick. This is called erythroblastosis fetalis during pregnancy. In the newborn, the condition is called hemolytic disease of the newborn. (Vucinovic M, Jadric H, Karelovic D, Roje D, Haspl-Hundric Z, Hrgovic Z, Vucinovic Z, 2004). Hemolytic disease of the newborn (HDN) occurs due to maternal IgG antibodies crossing the placenta thereby producing hemolysis mainly due to Rh, ABO and Kell groups. A systematic approach to the Rh HDN involves an obstetric history of previous isoimmunized baby, timing and regular monitoring of maternal Rh antibodies and pigment assay of amniotic fluid. Timely decision regarding in utero transfusion and early termination of pregnancy based on the maternal monitoring has radically improved the outcome of these babies. Antenatal prophylaxis with anti D has resulted in great reduction in the magnitude of Rh problem. The fetal blood sampling and in-utero intravenous transfusions has made it possible for almost 100% survival of isoimmunized pregnancies without hydrops. Alternative methods--IVIG and plasma exchange are still of limited application. ABO HDN though common is not a serious form of disease and dose not warrants invasive antenatal monitoring. Anti-Kell is found in patients hav ing received multiple transfusions and the rapid progress of hemolysis in them may not allow such systematic follow up as in Rh HDN. (Narang A, Jain N, 2001). Antibodies are produced by B lymphocytes. Maturation culminates with migration of the B cells to the reticulo-endothelial tissues of the body including the lymph nodes and parts of the spleen, bone marrow, liver, gastrointestinal tract and other tissues. Antibodies are a miscellaneous mixture of serum globulins and share the ability to bind individually to specific antigens. Those serum globulins with antibody activity are known as immunoglobulins (Ig). All immunoglobulin molecules have common structural features. The part of the molecule that binds to the corresponding antigen is different in each immunoglobulin. The basic

Propaganda - Essay Example Or it is being associated with something that is identified as a wrong or incorrect. However, in certain Latin countries, such association is rare rather propaganda is linked with the term of advertising. However, in both the world wars, both sides heavily used the tool of propaganda against each other openly terming their actions something deceptive or something that cannot be trusted. Additionally, intent is a necessary condition for the purpose of propaganda (Cunningham, 2002). Propaganda is based certain characteristics- such as time, total, truth, trust and trigger. Each element of propaganda is separately usable both in wartime as well as in peacetime. Basically, propaganda is a type of persuasion determined and implemented to keep a targeted audience to think in the required way. And it is used to target on the emotional side of the targeted audience rather than on the logical and argumentative side. As most of the time propaganda does not look logical, some propaganda techniq ues are used to do so. First, trigger is used like a bandwagon appeal. In which, the audience is emotionally molded in a way to do something because everybody else is having and doing it. It is based on the concept of molding an aggregate behavior and action. Consequently, the audience is asked to follow the trend. Additionally, a stereotype or total concept of propaganda is based on a fixed idea relating to all members of a group. As a result, actions of all group members are observed with only one single but total idea and on the basis of it, the members of the group cannot be separately identified. Additionally, trust is established when a testimonial comes from a personal recommendation of a famous or renowned personality from or the one who can be trusted because of its position or bearing on to the topic. It can be a personality, institution or anything else on which mostly creditability is attached. As a result, trust is established and used. It can be used for either negativ e or positive propaganda. However, most of the time, in advertising campaigns such characteristics of propaganda is used to achieve the desired outcomes. In the given picture, a non-verbal propaganda may be used with integration propaganda. Integration propaganda is defined as an attempt to depict the interests and positions represented by officials, who support a particular propaganda message. It is an American flag carrying words â€Å"Thank you.† Now, nothing is appearing anything suggesting being a part of propaganda. There is no extra message written on it. It would have been a propaganda message if it had certain words or sentences like ones mentioned at website-civilization.ca, where certain historical posters are provided on which a flag with additional words or sentences are written in a way to propagate certain information such as â€Å"HELP THE BOYS TO KEEP THEM RUNNING† (Civilization. Ca, n.d). Additionally, above mentioned sentence is not only provided wit h some soldiers, but also it is being shown that they are in trouble, they are being fired by the enemy forces and they must be helped. Such propaganda posters represent the way propaganda should take place as they have certain emotional attachment and emotional appeal as well. On the other hand, the given picture holds nothing

Chocolate History Essay Example for Free

Chocolate History Essay All chocolate starts with a seed called a cocoa bean that is grown on a small tree. Many countries in Central and South America produce cocoa beans. The history of chocolate starts in Latin America, where the cocoa bean was first discovered about 2,000 years ago on a tropical tree. The first people recognized to have used these beans to make any kind of chocolate were the Maya’s. They called it the kakawa bean, which is where the origin of the world chocolate began. They most often used the bean to make a spicy, foamy drink. Later, the Aztecs discovered the cocoa bean. Eventually this was introduced in Europe after the Spaniards came to Central America. When the Spaniards began experimenting with the bean, they began to add other spices to it, such as cinnamon and sugar, to give the chocolate a sweeter taste. Soon, the rest of Europe started drinking it and it became a popular drink that only the rich could afford. In the 1600’s the first chocolate house was opened and this flavor was able to reach the mouths of many other people. In the early 1800’s, solid chocolate was created. It became more affordable to everyone and throughout time more recipes were experimented with, creating many different types of chocolate. There are many different types of chocolate such as White, Dark (bittersweet), Milk, Semi-Sweet and even Baking Chocolate (unsweetened). White chocolate isnt really considered chocolate because it has no cocoa solids in it, it is made of the fat from the cocoa beans known as cocoa butter. White chocolate has a creamy consistency and taste. It lacks flavor because it contains no chocolate liquor which gives chocolate the bitter strong chocolate flavor. White chocolate is not normally used in cooking unless it is a replacement for dark or milk chocolate. It is used mainly for decorating. Dark chocolate is the healthiest type of chocolate. This chocolate contains a large amount of disease-fighting flavonoids, anti-oxidants also found in red wine and lots of different fruit and vegetables. Its anti-oxidants can significantly improve blood pressure, prevent blood clots, slow the oxidation of low-density lipoproteins (LDL) cholesterol making it less likely to stick to artery walls and also reduce inflammation. Eating dark chocolate can also lower insulin resistance, the main problem behind diabetes. Milk chocolate does not contain as much chocolate liquor as dark chocolate, which gives it a softer chocolate flavor. This chocolate is much sweeter than any other. It is the most popular type of chocolate. Milk chocolate is more difficult to temper properly and more prone to overheating which would make it thick and lumpy if it comes into contact with water. Milk chocolate can be used in pretty much anything you want to be sweet. The difference between regular chocolate and baking chocolate is baking chocolate has less sugar and no fat and its bitter while regular chocolate is sweet and sugary. Tempering means improving the consistency, durability or hardness of a substance by heating and cooling it. Tempering is done by melting solid chocolate to a temperature high enough that the crystals in the cocoa butter break down. Once the chocolate is fully melted, it must be cooled to about 82F, a temperature at which crystals will start to form again so that the chocolate can eventually re-solidify. The chocolate’s temperature is then raised back to about 90F, where it is very smooth and can be poured into chocolate molds and used for other things. White, milk and dark chocolate can be tempered. Tempered chocolate is very glossy, has a firm finish and melts smoothly at around body temperature. Chocolate that has not been tempered or that has been improperly tempered will look flat or discolored. Tempering can be done in 2 ways by hand, or through a process called seeding. Tempering by hand can be done by tabliering where melted chocolate is poured onto a cool marble surface and worked with spatulas until it has cooled down sufficiently. More melted chocolate is added back and incorporated in to the tabliered chocolate to bring it back to the final working temperature. Through the process of seeding, chocolate is melted and a small amount of finely chopped solid chocolate is added into the melted chocolate and stirred in. Adding solid chocolate will lower the temperature of the melted chocolate and it will start to temper the melted chocolate. When it comes to baking, chocolate does not need to be tempered because it is being incorporated into another form. Tempering chocolate is good for dipping foods, for a more clean finish.

Introduction to Sociology Essay

1. The Philippines is one of the third world countries in the world. This means that the country belongs to some of the poorest countries compared to the United States and the United Kingdom. People who live in third world countries are not necessarily all poor. Some of them are also rich and have their own businesses. These people can eat more than three times a day, send their children to private schools, and enjoy the luxuries that their money can buy. However, majority of the people in third world countries are poor. Some are homeless. Many have no source of income and therefore cannot provide for their families. It is not surprising that many people choose to go to first world countries like the United States to work for better opportunities. For Vicky, there is no doubt that the decision to find work in a foreign country was hard. She has her own family with a husband and two children to take care of. She left her family to earn money for the family. Although she did have a job in the Philippines, this was not enough to take care of the family’s financial needs. She did not want to be separated from her family but she needed to travel because she knew that if she stayed in the Philippines, her family will suffer. Vicky is not alone in this kind of situation. The Philippines is one of the most known countries who have the greatest number of overseas workers because of the situation in their country. They try to find work not only in the United States but also in Australia, the United Kingdom, and the Middle East. Financial need is the number one reason for them to work outside the country. 2. Because Vicky is not a native of the United States, it is most likely that she will experience some difficulties while working here. First, she might encounter discrimination due to her color and race. Although the United States is a very diverse country, discrimination still exists in its society at some point. Vicky might be looked down upon because of her color and her nationality. She might be discriminated because she is not able to communicate in English as fluently as the natives can. The United States government tries hard to make sure that discrimination does not exist in its society today. However, there are still a few who think that they are better just because of their color and race. Vicky might feel discouraged when she experiences discrimination from the natives of this country. She might also have an impression that Americans are not hospitable and welcoming and that working here is not worth it after all. Secondly, Vicky might encounter problems with her immigran t status. There are many employers who do not like to hire people who are not natives of the country because they do not trust them and believe of what they can do as workers. She might also have problems when her visa expires. The United States embassy is quite strict in allowing people in their country because they want to avoid terrorist attacks and other unwanted situations that foreigners can bring in the country. Another difficulty that Vicky might experience is the competition for the employment opportunities. Aside from the competition with the locals, Vicky might also have to compete with the opposite sex for the job that she wants. Some employers prefer to hire males because they believe that males are stronger and much more capable of the work needed to get done. This lessens Vicky’s chances of choosing a job that suits her the most and the job that she thinks would reward her the most in terms of salary and income. These are only some of the setbacks that Vicky might encount er while working in the United States. When one looks at the situation, it can be seen that Vicky and all other overseas workers are the ones who suffer the most. They enter a foreign country without any familiar face. They have to adapt to certain rules and norms of the country’s society. They have to learn how to get along with strangers just to keep their jobs. They have to endure problems like discrimination and competition. Aside from these things, they suffer from being away from their home and families. They get homesick but do not mind this just to be able to send money to their homeland. They take care of other people’s families and children but are not able to take care of their own children. All these they have to endure just for their families have a better life back in their homeland. 3. People from third world countries will not be able to think of leaving their families to go to another country if there are no available jobs in these foreign countries. Â  In economic terms, there would be no supply of workers if there is no demand for them. Vicky would not have thought of going here if there were no couples who need her services. Americans are very success-driven people, which is why they work hard day and night even if this means having less time for their families. Work is very important for them. At times, one job is not even enough and they search for second jobs to earn for the family. This requires them to look for people who can take care of their children while they are at work. While they certainly can avail the services of day care centers, many parents do not want to leave their children in these centers because of overcrowding and fear of their children contracting diseases from other children. It is also better to hire a private nanny who can focus on their children on a constant basis. Day care centers have limited staff and there are times when the staff cannot attend to the needs of each child because there are just too much of them. Vicky, as a private nanny, can stay at home with them and do other household chores when the child does not need taking care of. Having one private nanny can also mean that the nanny can focus on the child’s growth and development at all times. The nanny can act as a second parent to the child when the parents are not at home. Her educational background and previous work experience might also contribute to her employment. Parents would want to hire people who know how to handle their kids and the household when they are gone. They want someone who can be trusted. Vicky’s experience as a school teacher can help her get employed because this means that she knows how to handle children. In addition, the fact that she is a mother of two children herself means that she has enough experience in taking care of children and rec ognizing their needs and wants. If these dual-career Beverly Hills couples choose to hire Vicky, they would certainly be lucky and benefit from it because of her qualifications. It is not everyday that school teachers from other countries apply for a housekeeper or a nanny. This would also be beneficial for the parents because hiring Vicky would cost less than enrolling their children in a day care center. 4. Transnational migrants are those people who belong to two or more societies at the same time. Although Vicky does not really own any property while in the United States, she can be considered as a transnational migrant because she belongs to two different societies at the same time. She is still a Filipino citizen and will most likely take vacations in the Philippines if her employers allowed it. She still practices the different cultures and traditions of the Filipino culture while in and outside of her home country. This may not be obvious but she nevertheless still does it. At the same time, living and working in the United States requires her to adapt to the customs of the country to fit in. She would learn the language, the government, and the people of the United States. She is employed here and is receiving monetary income, which makes her a part of the society. Even if she does not really want to, she still has to do it because this will make it easier for her to live in a foreign country.
