Beta amyloid

of Alzheimer’s is the accumulation of amyloid protein plaque in the brain. The plaques interfere with the connections between our neurons, which are needed to spread messages throughout our body. In healthy brains, amyloid proteins are degraded by a secretase enzyme, keeping the brain plaque-free. However, due to old age, family history, and environmental factors, this secretase enzyme does not function normally (Bachmeier 2013). This leads to the gamma and beta enzymes doing their jobs, but the…

In the brain, there is a build-up of a protein called beta-amyloid. As a result, some plaques are found in between dying cell inside of the brain. The tangles are in the neurons of the brain as an effect of breakdown of another protein called tau. The cell death occurs because of the death of mitochondria. Mitochondria produce energy needed for any cell to function and survive. In Alzheimer’s disease, the abnormally high amount of beta-amyloid damage brain mitochondria which leads to the…

Imagine forgetting where you placed things, what the date is, where you are at, or even what your own name is; that is a daily problem that people living with Alzheimer’s disease experience. I chose to learn more about this disease due to the many people I have grown to love and had to see deal with this disease in their later years of life. Also, I have volunteered at SpiritTrust Lutheran Retirement Community for several weeks each summer for the past three or four years and working with some…

‘With an estimated 425,416 individuals living with it, Dementia is the second leading cause of death of Australians contributing to 5.4% of all deaths in males and 10.6% of all deaths in females each year.’ (Dementia Australia, 2018) Genetic testing is a fundamental phenomenon in 21st century society. Testing processes reveal the likelihood of an individual inheriting, passing on, or living with a suspected genetic condition. These medical tests identify any changes in proteins, chromosomes or…

Alzheimer’s Disease is a mental deterioration that usually affects the elderly but the signs and symptoms can come up in middle age. It can cause dementia and can hinder the person’s abilities of performing normal daily tasks of driving, self-care, and basic day to day duties. Many do not think that Alzheimer’s will affect them but the statistics are high. Alzheimer’s does not only effect the individual it has impacts on the family members and society. With research we take a deeper look on how…

Insulin (from the Latin, insula meaning island) is a peptide hormone produced by beta cells of the pancreatic islets, and it is considered to be the main anabolic hormone of the body. It regulates the metabolism of carbohydrates, fats and protein by promoting the absorption of, especially, glucose from the blood into fat, liver and skeletal muscle cells. In these tissues the absorbed glucose is converted into either glycogen via glycogenesis or fats (triglycerides) via lipogenesis, or, in the…

Recent research on the effects of sleep deprivation on the adolescent mind caused by early school start times, and the body’s circadian clock, suggest later school start times would benefit high school students. Adolescents need at least 9 hours of sleep each night to be able to function in the morning. However, Larry Gable and Kate Kinsella (2013), a professor and neuroscientist at San Francisco State University, and the authors of “Adolescent Sleep Research- Findings for Secondary Schools,”…

Memories are cherished and treasured. Whether it is good or bad, those happy and sad memories are engraved in us and cannot be taken away from us. But what if as we aged, those treasured memories are fading and soon to be losing? Currently, it appears almost every individual has experienced, or has a loved one who are being taken away of a very serious and often can be a fatal disease known as Alzheimer’s disease. Alzheimer Disease (AD) is one of the most common genetic disorders marked by…

protein inhibits the brain cells to keep their homeostasis and get their essential materials that are suppose to be transported by the protein to keep them alive. Another factor in that contributes to the brain cells to die are clumps of the protein, beta-amyloid, which creates…

the gene for the protein on chromosome 21, which is the same for Down Syndrome. APP is clipped outside of the surface of the cell, and sheds. In Alzheimer’s disease, APP clips above and below the cell surface and the result is a fragment called beta amyloid, which starts the destruction of the brain. 3.) Family members and caretakers have to deal with the emotional toll that Alzheimer’s disease causes. Family members and caretakers have to deal with a lot of stress when it comes to…
