Barth Syndrome essays

Barth Syndrome essays Barth Syndrome is a genetic disorder that only effect males. It is an X-linked ressive genetic condition. A mother that carries the genetic code for Barth Syndrome will never show signs or symptoms of it. She will always pass it to her daughters, and will have a fifty- percent chance of passing it to her sons. The daughters will never show any signs or symptoms either. Barth Syndrome only effects only the males. If a male does inherit Barth Syndrome from his mother, he only has a 30% chance of living through his first few years. Of the 30% that are diagnosed, those who seek treatment have an 85% - 90% chance of living in to their fifties. Barth Syndrome had many effects on the male body. An effected male will be far below average in weight and height. The lack of growth in the boys is often looked at as evidence of poor nutrition or some other effects of an illness, the termed used for this is failure to thrive. The effected person will have muscle fatigue. This includes all muscles, even the heart. They have a cellular deficiency that effects their ability to produce energy, causing activities that require strength or stamina, extremely difficult. Activities like walking to growing to writing. The boys also experience Neutropenia. It is a weakness of the immune system. Specifically its a reduction in the number of neutrophils. A neutrophil is a white blood cell, whose responsibility is to fight bacterial infections. Neutropenia places the Barth boys at an increased risk of acquiring serious infections. These infections may include bacterial pneumonia and skin abscesses. Treatment of Barth Syndrome can be tricky. A doctor was troubled with the case of a 3-week-old male baby admitted for congestive heart failure. The doctor did an electrocardiogram that revealed an unusual camels hump of the T waves and progressive thickening of the left ventricular wall with increa ...

Free Essays on Sir Issac Newton

Newton, Isaac (1642-1727)Newton, Isaac (1642-1727) Isaac Newton was born in Woolsthorpe, Lincolnshire, a premature infant not expected to live. His father (of the same name) had died just three months before. His mother, Hannah Ayscough Newton, remarried when he was three, and left him with his grandmother until her second husband died, in 1653, when Newton was 11. He was educated at King's School, Grantham, and it was assumed he would continue in the farming tradition of his family, but finally his mother became convinced that he should be prepared for entry to university, and in 1661 he went up to Trinity College, Cambridge, as a poor scholar who would have to earn his keep by doing menial tasks for the Fellows. Newton showed no particular promise in his early years at Cambridge, but Isaac Barrow, who held the Lucasian chair of mathematics, gave him much encouragement. Newton took his degree without distinction (in 1665), and would have prepared for his MA, but in 1664 the Great Plague broke out in London, and the university was closed down the following year. At home during the plague years, he studied the nature of light and the construction of telescopes. By a variety of experiments upon sunlight refracted through a prism, he concluded that rays of light which differ in color differ also in refrangibility - a discovery which suggested that the indistinctness of the image formed by the object-glass of telescopes was due to the different-colored rays of light being brought to a focus at different distances. He concluded (rightly for an object-glass consisting of a single lens) that it was impossible to produce a distinct image, and was thus led to the construction of reflecting telescopes, perfected by William Herschel and the Earl of Rosse. At the same time, he was working out his ideas on planetary motion. On his return to Cambridge (1667), Newton became a Fellow of Trinity College, and, in 1668, took his MA. In the fo...
