Article Review Cell Transfer During Pregnancy Essay

Article Review Cell Transfer During Pregnancy - Essay Example The main point in the article was that cells’ crossing the placenta is an established fact (microchimerism) but that new research is suggesting that these same cells can result in health or illnesses in both the mother and the child for a considerable time after the sharing occurred. Also that these cells can persist for an indefinite period of time and can become part of the body’s organs. There are instances when microchimerism can cause an immune attack in some individuals, but in some cases the body can actually be helped to heal through the same interplay of cells. Two examples in the paper showed an example of this. Firstly mothers who have rheumatoid arthritis can often have an improvement in their symptoms when they are pregnant, but that the condition returns after birth. This was initially considered to be because of higher levels of Cortisol in the blood of the mother, but because this phenomenon is not consistent in all cases (it doesn’t work for some women) this idea as discounted. Studies are now considering the disparity in Class II HLA’s as a possible reason for the decrease in symptoms during pregnancy. The second example was juvenile dermatomyositis. In this case transferred immune cells (mother to foetus) can result in an attack on the child’s body tissues. Another case in children is scleroderma and neonatal lupus. In both of these cases the adopted cells can cause the host body to attack the affected body tissues. The final point in the article was that this transfer could be harmful for some, and a helping aid in others. The reasons why this is the case seems to differ from case to case and more research is needed to determine how and why this happens. The transfer of cells between foetus and mother has been well documented especially in studies relating to negative impacts the mother can have the on the babies health through the ingestion of alcohol and other harmful substances. The foetus is basically plugged

The Waldens Freedom - Essay Example Thoreau believes that without the demands of modern life, people can be free to develop themselves as individuals. Buckner believes that the most important message of Walden is â€Å"to call people to freedom as individuals.† She stresses: â€Å"One looks at nature in order to learn about oneself; one simplifies one’s life in order to have time to develop the self fully; one must honor one’s uniqueness if one is to know full self-realization† (Buckner 4). Thoreau recommends to others that they should live simpler lives for them to be happier. A simpler life away from material needs exemplifies the idea of peace. Nature itself is filled with peace, which is the symbol of inner peace of mind. Thoreau cries out for a simplified life: â€Å"Simplicity, simplicity, simplicity! I say, let your affairs be as two or three, and not a hundred or a thousand; instead of a million count half a dozen, and keep your accounts on your thumb-nail† (Thoreau 395). He a rgues that a simpler life has fewer goals and priorities. People living in the woods can definitely trim their accounts to the bare minimum essentials of life. In modern life, this can refer to living simply, such using cash instead of several credit cards, so that one’s lifestyle becomes equal to one’s income. Living simply also entails eating the natural way, such as through cooked â€Å"real† food and not processed food and avoiding eating out, because dining out can be expensive when done on a daily basis. These practices will lead to a simple life with no more financial troubles.
