Without any thought, without even noticing it happens, when one has an itch, they scratch it. The arm moves up to the face, the fingers reach down and move across the skin. This series of actions, which many of us do everyday is something individuals with Parkinson's disease struggle with every moment of their lives. Simple movements are replaced by frozen limbs that they or their nervous system can not move. Described by many as a type of momentary paralysis, the disease causes gradual degeneration in patients until they are no longer able to perform the most basic bodily functions, such as swallowing or blinking.
Parkinson's disease is a neurological disorder that is named after "the English physician who first described it fully in 1817" (4). The disease causes disturbances in the motor functions resulting in patients having trouble moving. Other characteristics that are not always present in every patient are tremors and stiffening of limbs. All of these characteristics, of the disease are caused by "degeneration of a group of nerve cells deep within the center of the brain in an area called the substantia nigra" (5). Dopamine is the neurotransmitter for these cells to signal other nerve cells. However as the cluster of nerve cells fail to operate, the dopamine can not reach the areas of the brain that affects one's motor functions (5). On average Parkinson's patients have "less than half as much dopamine in their systems as healthy people do" (8). The problem and controversy that arises from this disease is in the cure. Researchers, for years, have been attempting to unravel the mystery of what causes Parkinson's disease and how it can be treated and or cur...

- Parkinson’s Disease Parkinson’s Disease (PD), known for its degenerative abilities and debilitating affects, is an illness that affects approximately 1 million Americans. The cause of this disease has not been pinpointed, although strides have been made towards a cure. As our elderly population increases, so does our overwhelming need to find a suitable cure that may one day eliminate this disease. Concepts of PD After watching the video: My father, My Brother, and Me, viewable at www.pbs.org , I took away four significant concepts pertaining to PD.... [tags: Disease/Disorders]

- ... Those who oppose the use of embryonic stem cells feel destroying the potential of what the embryo could become is in essence murder. Along with this view, others feel that this kind of research is scientists essentially playing God and that it could lead to human cloning. With no real breakthrough people argue whether or not stem cells actually have any beneficial aspect. For those who support stem cell research the benefits that come with it are too important to give up on. With the potential to cure diseases and other possible benefits not yet discovered stem cell research could provide the answer for many people’s suffering.... [tags: Stem cell, Embryonic stem cell]

- ... Pluripotency alters adult cells’ genetic information into an embryonic state (Morin NP). According to an article in the Los Angeles Times,“The process of pluripotency pioneered by Dr. Shinya Yamanaka and recognized with the Nobel Prize in 2012 is extremely inefficient, with a 1% success rate” (NP). This process is uncommonly used because somatic cells are usually thought to only fix certain organs based on the original type of cell, but they can actually be used to differentiate and become other similar cells (Crosta NP)....

- ... Once the news of Dolly had been known, controversies had arisen about human and stem cell cloning. To this day, arguments on the subject still arise in many classrooms, laboratories, hospitals, and political debates. Cloning, just like politics, religion, and other scientific discoveries, brings forth controversies that many people and scientists take a definite side on. According to an article on “The Ethics of Cloning” (Savulescu, 2005), a major con against cloning, both therapeutic and reproductive, is the safety....

- The a priori position of support for the public funding of scientific and biomedical research surrounding human embryonic stem cells is inherently hinged upon the promise of innovation for the clinical benefit of therapeutic potential, the potential provision of life-altering therapies for the altruistic amelioration of debilitating and devastating conditions, and the potential for improvement of quality of life, which leads to realizing and embarking upon the quest for curative therapies. While this optimistic perspective lends itself well to the exploration of the potential for the advancement and eventual implementation of innovative biomedical technology into clinical practice, several f...

- Envision a euphoric world where a couple insignificant little cells had the possibility to cure horrible chronic diseases like cancer. Picture how incredible that would be. Now imagine this, the only sacrifice you would have to make to save millions of people, would be killing a few babies here and there. Now how does that sound to you. Sounds like a rapidly developing dilemma. If that was your initial thought, you were correct. This dilemma is called embryonic stem cell research, and it has caused conflicts with peoples’ opinions, morals, and religion for years.... [tags: Biology, Cells]

- Over the past decade, stem cell biology has been an area that has caused much controversy. Stem cells have the ability to differentiate into many different types of cells and therefore, advocates of stem cell research argue that the cells have various medical applications. On the other hand, opponents of stem cell research denounce the use of human embryos for research purposes, claiming that the embryos represent human lives and that experimentation with them and subsequent annihilation of them is the same as killing a living human being....

- Should Stem Cell Research be prohibited. The ongoing bioethical controversy of stem cells research has been debated in political arenas across the world. As with any debate there are two sides to the issue. Scientific researchers want to expand their research into emerging fields like stem cell research in hopes of bettering medicine for the future. Human right activists and some religious groups are against this type of research because the harvesting of stem cells from embryos is seen as the destruction of human life....

- An Assessment of The Greatest Medical Breakthrough the use of Pluripotent Stem Cells A critical review of the pro and con analysis, of arguably, the most controversial issue of the 21st century—the use of pluripotent stems cells. In addition, the ensuing synthesis and prescription based upon empirical data and critical thinking. Given the enormous promise of pluripotent stem cells to the development of new treatments for the most devastating diseases, we believe our scientific researchers and medical professionals should be permitted and encouraged to simultaneously pursue pluripotent stem cell research....
