The Controversy over Stem Cells and Parkinson's Disease
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...

After a war that claimed the lives of more men than that of all other wars combined, much of the country was left in ruins, literally and figuratively. Dozens of towns in the South had been burned to the ground. Meanwhile, the relations between the North and South had crumbled to pieces. Something needed to be done so that the country could once again be the United States of America, not the Divided States of America. The years from 1865 to 1877 were a time of rebuilding – the broken communities and the broken relations. This time period was known as Reconstruction. Reconstruction was a failure on the basis that the 13th, 14th, and 15th amendments that were passed should have given protection and freedom to the African American people, instead, it actually hurt them because the laws were not enforced, and eventually lead to the organization of white supremacy terrorist groups.
One great quality of heroes is their devotion to help others in need. They see importance in all life, no matter animals or humans. In a poem, “Gracious Goodness” by Marge Piercy and short story, “What Happened During the Ice Storm” by Jim Heynen, the reader can see that a hero is someone who just wants to help others. In “Gracious Goodness” the speaker is depicting of a royal tern on the brink of death, as it was crippled with a hook and the fishing line. The speaker decided to help the royal tern out of the kindness of the speaker’s heart. The sp...
... and slavery left millions of newly freed African Americans in the South without an education, a home, or a job. Before reconstruction was put in place, African Americans in the South were left roaming helplessly and hopelessly. During the reconstruction period, the African Americans’ situation did not get much better. Although helped by the government, African Americans were faced with a new problem. African Americans in the South were now being terrorized and violently discriminated by nativist groups such as the Ku Klux Klan. Such groups formed in backlash to Reconstruction and canceled out all the positive factors of Reconstruction. At last, after the Compromise of 1877, the military was taken out of the South and all of the Reconstruction’s efforts were basically for nothing. African Americans in the South were back to the conditions they started with.
Parkinson's Disease is a mysterious disease that affects the central nervous system and can be very difficult to treat and live with. It is classified as a motor system disorder but is a progressive, chronic disease resulting in
The four key symptoms of Parkinson’s disease are tremors of the hands, arms, legs, or
The author talks about how this was not something that happen overnight, but has been discussed about from a very long time such a 1989. The views of people that the author chooses to look at are Ernest Cheniere, who raised the statement of banning headscarves in public schools in 1994 and Francois Bayrou minister of education in 1994 who saw muslim headscarves as a way of proselytizing. Then Joan Scotts talks about why the timing played into affect, how racism such as colonial legacies were effected, secularism, individualism of the veil, Muslims being looked as threats, how uncivilized Muslim people were, and sexuality. Joan Scotts goes into detail in all the sub topics and shows how does this affect a common Muslim girl that wears a hijab and how does the French government view
Parkinson's is an idiopathic, multifactorial neurodegenerative disease that attacks neurotransmitters in the brain called dopamine. Dopamine is concentrated in a specific area of the brain called the substantia nigra. The neurotransmitter dopamine is a chemical that regulates muscle movement and emotion. Dopamine is responsible for relaying messages between the substantia nigra and other parts of the brain to control body movement. The death of these neurotransmitters affects the central nervous system. The most common symptoms are movement related, including shaking, rigidity, slowness of movement and difficulty with posture. Behavioral problems may arise as the disease progresses. Due to the loss of dopamine, Parkinson's patients will often experience depression and some compulsive behavior. In advanced stages of the disease dementia will sometimes occur. The implications of the disease on the anatomy and physiology of the respiratory and phonatory systems significantly control speech.
Most signs and symptoms of Parkinson disease correspond to one of three motor deficiencies: bradykinesia, akinesia, tremor, and rigidity. The first two qualities are usually present before tremor, but often attributed to aging by the patient and even the physician, and thus the disease is rarely diagnosed until tremor becomes evident much later. An average of 80% of the nigrostriatal neurons may have already degenerated by the time Parkinsonism is diagnosed, which complicates treatment (Fitzgerald, 130). Bra...
Reconstruction was needed and the period following the civil war, the reconstruction period, fostered many significant results and achievements especially for Constitutional amendments. While mending a broken country, the reconstruction period still left many fresh wounds. There was great successes and championships for former slaves and the blacks rights, but their was still lingering thoughts and acts of discrimination towards these groups. Reconstruction produced three amendments defending the people 's rights, yet discrimination towards blacks was peeking to new heights. Laws were not enough to change the hearts and minds of the people, which was at the core of the issue. With the unfortunate loss of the nation’s leader, it would be almost a hundred years later until America had leaders strong enough, in the nineteen sixties, that could change the ideas of racism and
If the Charter claims that everyone is entitled to their own beliefs and expressions, then why is the discussion of prohibiting public employees from wearing clothing with religious symbolism even brought up? Why are the majority – 60 percent – of Quebecers in favour of the Charter's ban on religious symbols? Perhaps it is difficult to understand the importance of such religious symbols when someone is not practicing any religion and are not required to wear anything to show their faith. However, imagine having something that you find greatly important and highly value being taken away from you. It does not have to be a cross or a hijab, maybe it is a favourite piece literature, or a piece of jewelry passed down from an important family member, whatever it may be, it holds high sentimental value. Taking away an object of high value would offend and upset anyone, no matter what that object may be. When it comes to taking away someone's right to wear whatever they wish, and on top of that halting their right to properly practice their religion is a definite infringement of the Rights and Freedoms possessed by any person living in Canada, which is just

The veil affair, or rather the scarf affair, in France is a controversial topic, which resulted in the creation of legislation prohibiting "conspicuous" signs of religious affiliation in public schools. This article of law, was pointedly aimed at young Muslim girls who wore the hijab in state schools. Proponents of the law argued that it was a defence of laicite, a French principle which is described as delegating religion to the private sphere, and out of the public civic sphere. Joan Wallach Scott writes, that such legislation, or separation is the state acting to protect individuals from the claims of religion. Scott, further says that laicite, is an instrument of the state to create acceptable forms of religion, which has justified the exclusion and
Drones are the latest and most efficient weapons the US has used abroad in military zones, especially in the Middle East. As the US slowly withdraws from that region, questions are being asked and some are still waiting for answers: What are Drones? Can these ideal machines be converted for domestic usage? What implications will these have towards the safety of the people and their rights? These questions lead to unmarked territory. Legal scholars, lawmakers, and the military have different ways of twisting laws and regulations to get what they want leading to the general public concerns.
Should countries be allowed to use drones in modern countries? Since the installment of drones in warfare, the unmanned aerial combat vehicle has proven to be quite an effective tool. Nowadays, the efficiency of drones has overpowered the opposing arguments since it has more pros than cons. By defining the importance to keep military personnel safe, by providing coherent data on civilian lives, and by refuting the significance of drones to keep terrorism at bay, one will be enlightened to see that drones are the way of the future.
Today, more and more people are using drones. Drones are fairly new and so there are not many restrictions on them. For avid hobbyists, drones are a fun way to pass the time, however, criminals can easily manipulate drones and cause panic to the public. One concern of the public with drones is that drones have the ability to invade people’s privacy. The government uses drones to carry out airstrikes on suspected terrorists although it’s a useful tactic, the airstrikes can easily kill innocent civilians. Drones can be a fun way to pass the time, but in the wrong hands can cause a lot of problems. The government needs to keep a close eye on drones and put regulations in as needed.
