"An exploration of genes, inheritance and gene therapy for diabetes" - Essay Example Besides, if one’s exposure to the microorganism is delayed due to the better standards of the living, which hinders the development of the immune system causing to make the person vulnerable to this disease. Gene therapy is the method by which one foreign gene into any cell is introduced into the body of the patient in order to produce insulin. The introduced gene could be the insulin gene itself, but it must be controlled by specific tissue promoter which is encoded as a factor in order to activate the insulin gene (Kelly, 2007). Cell transplantation is more successful treatment for diabetes as compared to the method of using insulin injections. The transplantation of organs, tissues or cells between animal species usually provides a number of beta cells, which is known as xenotransplantation. The most suitable donor of organs or cells is the pig but the major problem in using the pig’s organs for transplantation is that it is difficult to obtain in the tissue culture and the islets of the adult pig because of their poor survival. One more serious problem in xenotransplantation is an infection, which occurs because of the endogenous porcine retroviruses, which has a potentiality to infect human cell in vitro and vivo (Allman, 2008). Expansion of the primary beta cells and beta cell precursors can also be helpful in gene therapy. Beta cells are normally present in small bodies deep rooted in the pancreas known as islets. Beta cells do not have enough capacity for replication. There are a number of gene transduction methods in practice in the world in order to treat different disease including diabetes. These include viral and non-viral methods (LeRoith et al., 2004). Non-viral methods such as calcium phosphate co-precipitation are a very simple and an affordable method for genetically modifying pancreatic cells. When calcium

Chinese literature Unit 3 - Essay Example u’s â€Å"Praying For Rain,†1 from the Chou period, and the poem â€Å"Sitting and Forgetting,†2 from the Nine Songs, from the latter Chu period, and examine how each portray and think about ritual. The first shows a more straightforward approach to ritual—as in a kind of rain dance which is a means to an end. The second show ritual and its relation to nature as being potentially personally transformative. In â€Å"Praying for Rain† the poet describes the rituals or etiquette that surrounds rainfall, the harvest, and agriculture. Back then there was no agricultural science. Most farmers believed that a good harvest came because the gods were happy. The harvest was hugely important for everyone because the population relied on it for nourishments. It therefore made sense that rituals and prayers that poets and priests believed would help the harvest would be of huge importance and would frequently be refined and added to in order to ensure the best possible harvest. Poetry and ritual at the time were in some sense a matter of life and death. Ku Liang Shu describes the correct time to pray for rain to improve the crops.3 He says that petitioners must wait until the last minute, until it becomes clear that the rain is absolutely necessary, before engaging in the ritual prayer. By praying, man is â€Å"asking for a favour† the poet rights. These things must not be taken ligh tly. The power the gods have over people is one of life and death. There is an additional social aspect to this view of rituals: favours are important things and should be frivolously asked for. Ask only for what you need. We see in this work that rituals are taken very seriously and are mostly a way of communing with the gods, rather than with people (although there can be social implications to these rituals). The â€Å"Sitting and Forgetting,† one of the Nine Song, focuses much more on an abstraction of the ritual and its power to transform the world or the poet’s perspective of the world.
