Stem Cells A Type Of Cell - 1436 Words

Stem cells is a type of cell that can differentiate (alter, transform) and form different tissues in the body. This is a special capacity because the other cells can generally only be part of a specific tissue (for example skin cells can only constitute skin). Another special ability of stem cells is self-replication, which means that they can produce identical copies of themselves. Because of these two abilities, stem cells are the subject of intense research today, it could in future act as replacement cells in injured or diseased tissues, as in cases of Alzheimer, Parkinson and neuromuscular diseases in general, or replace cells that the body stops producing for some deficiency, as in the case of diabetes. Adult stem cells are present in bone marrow, blood, liver, umbilical cord and so on. Scientists still tries to preview what kind of adult cell, a specific stem cell will become. It is known of its replication capability, but it is unknown what their limitations as transplants and for genetic diseases. In other words, it will take longer research efforts and long-term investments until an effective therapy with these cells present results. But when it comes to scientific research, any new fact, any new discovery can completely alter the current situation, and many steps can be overcome in a short time. On the other side, embryonic stem cells, can turn into any human tissue (cell), but researches with those type of cells happens only in countries that allow this type ofShow MoreRelatedThe Types Of Stem Cells1665 Words   |  7 PagesStem cells are a special type of cell that has the potential to differentiate into many different cell types. They work with in the body as an internal repair system. When they are not being used as a repair mechanism, the stem cells have the capability of long-term renewal.

Life Without Television Free Essays

When my family’s only television set went to the repair shop the other day, my parents, my sister, and I thought we would have a terrible week. How could we get though the long evenings in such a quiet house? What would it be like without all the shows to keep us company? We soon realized, though, that living without television for a while was a stroke of good fortune. It became easy for each of us to enjoy some activities alone, to complete some postponed chores, and to spend rewarding time with each other and friends. We will write a custom essay sample on Life Without Television or any similar topic only for you Order Now First of all, with no television to compete for our time, we found plenty of hours for personal interests. We all read more that week than we had read during the six months before. We read a lot of books such as Obama’s biography, â€Å"Dreams from my father† by Barack Obama, â€Å"Heaven is for real† by Tomas Nelson, and â€Å"Unbroken† by Laura Hillenbrand. Before we lived without television, we watched some dramas instead of novels and we watched cartoons such as family guy instead of cultural books. Through we read books we could have discussions about books that we had read. We each also enjoyed some hobbies we had ignored for ages. We started to go hiking every weekend which was my mother’s hobby. In addition, my sister and I both stopped procrastinating with our homework. When we were doing homework, we need a lot of time to finish it because of Television shows’ sounds. But we realized that we could do homework a lot faster than when we were with television. Second, we did chores that had been hanging over our heads for too long. There were many jobs around the house that had needed attention for some time. We painted near the windows and we repaired a doorknob that didn’t work for a long time. We also had a chance to do some long-postponed shopping. Go shopping with family was one of my sister’s wishes. She was so happy and entire family members wear a smile. Our family became more active than we had a television set. And each of us also caught up with e-mail and did paper work that was long overdue. After that, we started to realize that television had killed our time so much. Finally, and probably most important, we spent time with each other. Instead of just being in the same room together while we stared at a screen, we actually talked for many pleasant hours. I had never thought about what my family members’ worries. Through we were talking each other, we could share our troubles. Moreover, for the first time in years, my family played some games together. We played Monopoly, which was my favorite game, and Texas holdem poker, which was my father’s favorite game. And because we didn’t have to worry about missing this or that show, we had some family friends over on a couple of evenings and spent an enjoyable time with them. We realize that our family is the best friend. Once our television returned, we were not prepared to put it in the attic. But we had a sense of how it can take over our lives if we are not careful. We are now more selective. We turn on the set for our favorite shows, certain sports events, and the news, but we don’t leave it running all evening. As a result, we find we can enjoy television and still have time left over for other activities and interests. How to cite Life Without Television, Essays

The Story Flight

Question: Did Pepe ever become a man in the story Flight written by John Steinbeck? Answer: The story Flight reveals the tale of Pepe who happens to be a happy teenager and is described as an easygoing person who generally remains lazy. His mother Mamma Torres waits for him to grow up and actually become a man. He commits a murder on one instance and as expressed by the narrator, he does become a man (Bloom). This particular murder was committed by him using the knife of his father. Mamma Torres often compares her son Pepe to her hardworking husband who is no more alive. When in the story Pepe wields his fathers knife, it symbolizes his completion of childhood and entrance into manhood. He made use of the knife in the same way as his father but the only difference was that he used the knife with intent to kill a person. In the initial part of the story, Pepes mother was represented as a total caregiver of Pepe who scolds him but at the same time also feeds him. She takes care of Pepe and looks after all his requirements. Steinbeck uses the maternal figure in the story to convey the idea that Pepe actually grew up to become a man. In spite of giving him all the care, when Pepe goes to the city all alone, his mother confers a greater sense of responsibility on him. She gives up her hold on the family and in order to transform her son to a man, she bestows greater responsibilities over him. Pepe on the other hand, uses this opportunity with full enthusiasm and rather than getting through a small journey, he is made to confront death (Steinbeck). Pepes mother had put in a lot of trust over him and ultimately he succeeds in keeping through that trust. He leaves his boyhood behind and makes his journey. Steinbeck has very judiciously used characterization in order to convey the reflective change that took place in Pepe. Pepe, who once happened to be a lazy, euphoric teenager, metamorphoses into an entirely different person. The narrator in the story clearly indicates that He was changed. He further continues to state that There was no laughter in them (eyes) any more or any bashfulness. They were sharp and bright and more purposeful (Steinbeck and Covici). Under the influence of this changed being, Pepe is forced by his instincts to leave his home, his dear siblings, brothers and sisters and most importantly he leaves his mother. He tries hard to keep up the light of manhood that radiates from him. After being left out in the world around him, he has a total absence of security that he used to get in his home. The outside big world extends no shelter to him. This instinct of self realization in the life of Pepe continues till the end of the narration of the story (Steinbeck and WikstroÃÅ'ˆm). It primarily focuses on the survival strategies which Pepe resorts to in his exposure to the outer world after he becomes a man. References Bloom, Harold.John Steinbeck.

Nutrition Review of the Whole 30 Diet Essay Example

Nutrition Review of the Whole 30 Diet Essay The Whole 30 diet plan, also called the Whole 9 Life Plan, has been out since 2009, and I decided to review it because one of my friends is currently following it, she claims she has never felt better and has lost weight. The diet plan is classified as a high protein/paleo inspired diet, and there is a do eat and do not eat list. First there are foods that you can eat including: meat, seafood, eggs, vegetables, some fruit, and plenty of fats from fruits, oils, nuts and seeds. The foods you cannot eat include: ugar or any sweeteners, legumes, grains, dairy, carrageen, sulfites, MSG, and potatoes. The idea is to only eat whole, organic foods that are on the approved list. The claim is that the foods that you cut out can be psychologically unhealthy, hormone-unbalancing, gut-disrupting, and inflammatory causing foods. The diet is done over a 30 day period, at the end of the 30 days they encourage you to decide how you want to go forward with eating, it does state you should continue until you feel ready to stop, but they warn it isnt supposed to be the Whole 365 (day) plan. I believe while they have many testimonials singing the praises of this eating plan, it does fit the bill for a fad diet. The first red flag is the complete halt on eating dairy, grains and legumes, and the limitation of fruits and certain high starch vegetables. This way of eating lacks balance, it puts a huge emphasis on a handful of foods, most of which are high in fat. Since there is no limit on portions of what you can eat, calorie control is not considered important on the plan.

The problem with this is that when ketone bodies occur in the blood it can cause vitamin and mineral deficiencies, loss of bone minerals, cause elevated blood cholesterol, and impaired moods. (Sizer et al; 133-134) Your body is in a starvation mode that causes you to use your fat stores as fuel. This diet could cause a life threatening condition if someone went on it long enough. Whole grains contain fiber which helps promote normal blood cholesterol, and reduced risk of heart disease, promotes healthy body weight, and maintains healthy bowel function. Carbohydrates are needed to fuel red blood cells, and the brain and nervous systems. The problem with carbohydrates really lies with which kind you choose, it is important to pick whole grains over processed and refined ones. The encouraging of eating meat including unlimited consumption of red meat, bacon, pork, poultry and game is another red flag. All these foods contain saturated fat, and eating high uantities of these foods could be disastrous for ones health. This can cause high LDL blood cholesterol levels, heart disease, and other health problems including cancer. The other red flag for a fad diet is that it sounds too good to be true: cut out all these foods for 30 days and you lose weight and cure a list of health problems that run the gamut. It concerns me that on the message boards many parents are putting children on this diet in hopes of curing behavioral problems without consulting with a pediatrician or registered dietician. While the Whole 30 plan does have some good points with cutting out processed foods and additives such as MSG, avocado, but overall it is too extreme to be a wholesome eating plan. The only proper and long lasting, healthy way to lose weight is by overall calorie control, eating a varied whole foods diet, and getting exercise. Sources: Sizer, Frances.

Medical Technology Assessment Research Paper Example | Topics and Well Written Essays - 1500 words

Medical Technology Assessment - Research Paper Example From this paper it is clear that technology assessment is the evaluation of emerging and existing technology trends to substantiate their existence in the world today. It seeks to identify the relevance of these technologies, and the role they play in the economic stability of organisations and the world at large. Furthermore, it is widely believed that scientists are not trained ethics as such whatever innovation they create should be assessed for any ethical concern. Technology assessment is viewed as interdisciplinary and capable of identifying and solving a wide range of technology based problems. An important concern, addressed by technology assessment is the collingridge dilemma. This is the situation where impacts of a new technology cannot be easily predicted unless the technology is fully developed and used. Yet on the other hand, it is absolutely difficult to change or control technology once it is widely used.This report stresses that  the Cleveland clinic is an academic medical centre that has seen a tremendous growth over the years since its inception. It has a designated research laboratory, the Cleveland Clinic Lerner Research institute that is characterised by high technological advancements.  A quick look at the operations within and without this medical facility reveals a heavy reliance on technology and information systems.  This is a specialised type of technology assessment that informs management and relevant medical policy makers of the efficacy of medical systems.   The main purpose of health technology assessment is to obtain ground for decision making with regards to application of technology within the healthcare system (Healthcare, 2009). These decisions should be made systematically with adequate and well documented information so as to leave little or no margin for error.

Native American Essay Example | Topics and Well Written Essays - 1000 words

Native American - Essay Example The use of stringed instruments such as guitars and fiddles and the application of music synchronization to Indian music were initially introduced by the Europeans. With the migration of the Europeans and their African slaves to western Americas, both the European and African music started to influence Native American music traditions (Prinzing). In the American Indian humanity, music has always portrayed an important role — a medium of communication with the spiritual kingdom, and of inviting mystical force into their daily existence. It has become a fundamental expression of American Indian identity (Fields). â€Å"The importance of American Indian music is found not in its impact on modern scholarship and composition but in the traditions and values it expresses to and for the Indian people. This oral tradition has survived solely because the music was too important to be allowed to die† (1976). Indian songs are an integral component of any activity, and encompass power in and of itself (Fields). There are songs for all events. There are songs for the efficiency of labour, success in hunting and fishing, winning in betting and gambling, making of rain, safety of the home and the family, power to heal, abundant harvests, lullabies, songs of romance, worship songs, corn-grinding songs, social dance songs, game songs, and legend songs (Rhodes 6). Some Indian songs are for teaching roles in society. Lullabies not only put babies in deep slumber, but furthermore aid as guidance and preparation for a life ahead. The songs are intended to facilitate happiness, good health, and the making of a better person and a useful part of humanity. One Indian lullaby says, â€Å"My little son, you will put a sealing spear into your canoe, without knowing what use you may make of it when you are a man† (Densmore 226). Another lullaby for a little girl says, â€Å"This little girl will pick black salmon berries when the women go to get berries†
