lead to genetic‚ environmental‚ and age-related factors. Genetics factors cause of Parkinson’s disease through a mutation in the genes responsible for dopamine and other vital proteins. Environmental factors are thought to be associated with Parkinson’s in that exposure to certain toxins such as pesticides can play a significant role in the abnormal levels of dopamine produced. Age is also a definitive factor of the disease‚ because people under the age of 60 are rarely diagnosed (Triarhou‚

Currently‚ almost one million people in the United States are affected by this disorder (Parkinson’s Disease Foundation). However the cause is yet to be discovered and there is presently

through the small blood vessels and deliver oxygen to all of the body. Sickle cell disease(SCD) causes these red blood cells to form into a crescent shape‚ like a sickle. The sickle-shaped red blood cells easily break apart‚ causing anemia. Sickled red blood cells only live 10-20 days instead of the normal 120 days. The damaged sickle cells then clump together and stick to the walls of blood vessels‚ causing a blockage of blood flow. This can cause severe pain and permanent damage to the heart‚ brain

also serves as a large source of free radical generation in Alzheimer’s disease. Another possible mechanism involved in Alzheimer’s disease is the creation and accumulation of glutamate hydroxyl radical (Behl et al.‚ 1992) and also the over production of superoxide dismutase. This leads to the accumulation of hydroxyl radical produced from the conversion of hydrogen peroxide (H2O2). A characterization of Alzheimer’s disease is by the loss of the amyloid B (beta) protein which is in the neocortex

can not be taken from us‚ but what happens as we get older? As time goes by we begin to struggle due to losing memory. When Alzheimer’s Disease is mentioned‚ we often think about older people which make sense‚ because Alzheimer’s Disease symptoms begin before age 65 (Prevent and Reverse). Alzheimer’s Disease is a type of dementia that involves memory loss and causes problems with thinking and behavior that starts off calm but gets constantly worse. People who live with Alzheimer’s brain cells die‚

There is one quote that is used to describe the pardoners tale and it is‚ “Avarice is the root of all evil”. In the pardoners tale there are three men who are on a quest to avenge their friend and kill death.

In the beginning of their journey they come across an old man who knew where they could find death. The three men accuse the old man of being a spy for Death
