Aging). According to recent research, it is believed that Alzheimer’s is caused due to a build up of a protein, called beta-amyloid. This protein peptide is toxic and insoluble, and forms more predominantly in particular regions of the brain, compared to the plaque buildup in a healthy aging person’s brain. Beta-amyloid proteins form from a protein known as amyloid precursor protein (APP), which

distinct aspects involved in Alzheimer’s disease; beta-amyloid plaques and tau tangles. Beta-amyloid plaques are formed when the amyloid precursor protein (APP) which is present in the membrane of neurons (alz.org) is cleaved off by beta and gamma-secretases (Chen et al., 2001). In a normal brain, alpha-secretase does the cleaving and the body processes APP on its own (Chen, et al., 2001). In AD, the small pieces join to form beta-amyloid plaques but as smaller individual pieces they can interfere

brain. Growing old does not come with a guarantee to have memory loss. Using preventative measure and knowing the causes of this deadly disease will aid in a safe path that strays away from forgetfulness. Healthy lifestyles inhibits the formation of amyloid beta protein strands, the main cause of Alzheimer’s. Although living healthy can be more expensive, the money saved from the cost of therapy, prescriptions, and time-consumption from care giving is an advantage. The cost of healthcare and service

Calpain was first discovered within the brain, lens of eyes and other tissues by Gordon Guroff in 1964. This was done by isolating enzymes in both rat brains and skeletal muscles. These findings concluded that Calpains are calcium-dependent cytosolic cysteine proteinases. With further research, it was noted that Calpains are found in nearly all eukaryotes as well as some types of bacteria but, not within archaebacterial domain. Structurally, Calpains contain four functional domains with two domains

are 3 major subtypes of cardiac amyloid: light chain amyloidosis, hereditary transthyretin amyloidosis and wild-type transthyretin amyloidosis, also called senile systemic amyloidosis (SSA). SSA is almost exclusively a disease of the elderly caused by the deposition of wild-type transthyretin fibrils predominantly in the myocardium leading to progressive heart failure, arrhythmia and conduction blocks [3]. Post mortem studies have shown that the finding of amyloid depositis (wild-type transthyretin)

(ApoE4) which is located in chromosome 19 is linked to the onset and progression of AD. The synaptic loss is due to a loss of cholinergic neurones which transmits nerve signals in the brain which are known to be linked to memory formation (figure 2). Amyloid plaques cause this loss. S.McGREEVEY et al,2013. J. Cerebral Blood Flow & Metabolism, 2006,1562–1576. ACh and memory ACh helps in memory formation by facilitating cell to cell signalling of the cholinergic neurones in the frontal

In the present day, there are quite several diseases that have yet to be treated and or prevented. One of those is a neurodegenerative disease called Alzheimer’s. Alzheimer’s is defined by a depreciation of memory and other cognitive functions that can lead to death with in 3 to 9 years after it is properly diagnosed. The disease effects more than 35 million people in the world, 5.5 million are effected right here in the United States. The main factor that is known to cause this disease that we know

retardation. After the death of Auguste, Alzheimer had sent her brain to Munich for a thorough study to find out later that there are two lesions in the brain: senile plaque and neuro fibrillary tangle1. Senile plaques are extracellular deposits of amyloid-β and the majority species of it is Aβ40 and Aβ42, whereas the neuro fibrillary tangles are composed of defective tau filaments that are joined together inside neurons to form a round shaped tangle2. The senile plaque is formed by the interaction

In our previous study we came to the conclusion that excess and deprivation of arginine lead to amyloid plaques being formed in yeast. We grew yeast with a dropout arginine broth, which allowed us to use different concentrations of arginine. This showed us that amyloid like structures were forming at excess and deprivation of arginine concentration meaning arginine is an essential component to plaque formation. Then in a recent study by Duke University Medical Center, the pathology of CVN-AD mice

Alzheimer 's disease, or senile dementia, is a form of dementia that affects memory, thinking, and behavior. Brain cells and their connections are killed, and this is what causes people 's brain functions to fail. Scientist have yet to know what causes Alzheimer 's, but have discovered that age, family history, and genes contribute to developing the disease. Symptoms experienced by people with Alzheimer 's are poor judgement, poor decision making, inability to manage a budget, losing track of the
