This essay The Stem Cell Technique in Treatment of Alzheimer's and Parkinson's Diseases explores treatment options for Alzheimer’s and Parkinson’s disease. Currently available pharmacological therapies for Parkinson’s disease such as Levodopa, Selegiline, Amantidine, Anticholinergics, Dopamine receptor agonists, and Catechyl-O-methyl transferase (COMT) inhibitors can neither arrest nor reverse the progression of the disease; hence no cure has been found for PD so far. Ablative surgery for patients with Parkinson’s and other movement disorders, creates a permanent lesioning of tissue to ostensibly inhibit overactive neuronal activity. Deep Brain Stimulation (DBS) has replaced ablation of tissue in the basal ganglia and the thalamus. DBS mimicks ablation, without causing permanent damage (Benabid, 2003). Hardesty and Sackeim (2006) believe that the therapeutic properties of high frequency DBS on both white and grey matter targets are due to an excitatory axonal response. The mechanism of DBS is based on a combination of inhibition and excitation, resulting in neuronal jamming and silencing, as well as axon stimulation. By switching off the disrupting activity causing the movement disorder, the application of a new type of frequency that has beneficial effect, is possible. New research has introduced neurosurgical approaches based on ready to use and commercially available equipment for deep brain stimulation of the subthalamic nucleus, and also lesion or stimulation of the globus pallidus to a lesser extent.
This research paper examines the stem cell therapy as the best future treatment approach for Alzheimer’s and Parkinson’s disease, as compared to other options such as cell therapy and deep brain stimulation. Stem cell therapies consist of treatment measures related to regenerative medicine…
The pluripotent stem cells also referred as embryonic cells have the ability to differentiate into every cell of the body while the multipotent (adult) stem cells can only differentiate into multiple cells but not all cell lineages in the body. Research on stem cells spans a broad range of scientific and medical fields.
Stem cell research seeks to develop stem cells to regenerate cells for nonfunctional organs and tissues. Research in stem cell has begun long time ago but has gained popularity recently due to increased scrutiny from the public especially religious organizations.
A Creative Exploration of your own choosing. "Discussion the technology of cloning and the arguments that exist relative to it." . Using the template: Introducing an ongoing debate The topic of the debate is: The technology of cloning and the dispute! In discussions of the affects of the technology of cloning on the human society, one controversial issue has been that whether cloning should be permissible for the masses or not.
There is almost no area of medicine that will go untouched by this revolutionary research. As a person who comes from a family that has been impacted by hereditary, late-onset Parkinson's, the possibility that my grandchildren may be freed from the fear of this disease gives our family great optimism.
Under viable conditions, these 50-150 young cells can continuously divide and eventually differentiate to become any cell type. Upon its discovery, scientists became very enthusiastic in pursuing stem cell researches most especially because it shows potentials for treating several diseases.
The protestors claim that there is nothing good to be found in doing research off of a life that was not given the chance to even begin, yet others argue that life was not even present when the stem cells were taken. Of course the discussion is centered upon the majority of stem cells being obtained from aborted fetuses and embryos, which for many is not an acceptable action, even in the name of science and research.
Scientists are now able to produce neurons and glia successfully from stem cells in culture. Besides, the use of genetic engineering with stem cell therapies can halt the further degenerative process and can serve as a powerful therapeutic tool. Hence, there is hope for patients with these diseases and can gain from stem-cell-based transplantation therapies.
arch for the wellbeing of human since it believes that stem cell research can find answers to some of the genetic diseases and other serious diseases like cancer, heart problems etc. For example, around 30,800 annual leukemia cases are reported in USA including 10,800
According to the report there are a lot of ethical issues surrounding the use of stem cells in research and treatment. There are two types of stem cells as outlined by the American Medical Association and these include adult stem cells as well as the embryonic stem cells. These stem cells can be transformed into any type of cell.
