HMGB1 And Alzheimer's Disease Analysis

Cronos, by Guillermo del Toro, is a Mexican film about the lengths in which one would go to be granted immortality. Throughout the film, there are many nods to religion: the main character’s name is Jesus, there is a side character that wears a cross, and a significant portion of the film is set during Christmas. These homages to religion (Christianity in particular) could be emphasizing how religion is a major part of Mexican society. There is also a scene, near the beginning of the film, that shows the streets of the town where the movie is set. What is noticeable about this scene is that del Toro does not show a pristine street, but a messy street.

Alzheimer 's disease (AD) is a progressive degenerative disease of the brain from which there is no recovery. There are three brain abnormalities that are the hallmarks of the Alzheimer’s disease is initially caused by plaques buildup in the brain’s neurons as illustrated in figure 1. The support structure that allows the flow of the nutrients through the neurons gets damaged and ultimately there is loss of connection among the neurons and they die off (National Institute of Health, 2015). This causes the brain tissue to shrinks, which is called atrophies. All this ultimately lead the victim of this disease to face difficulties in governing emotions, recognize errors and patterns, coordinate movement, and remember. Ultimately, a person with AD loses all memory and mental functioning.

It occasionally happens to everyone.  You can’t find your glasses.  The grocery list is on the refrigerator, and you’re at the store.  You forget the new neighbour’s first name.

Alzheimer’s is a form of dementia that causes memory loss, thinking, and behavioral issues. Nearly 5.4 million American’s are affected by Alzheimer’s. People who are affected begin with early-onset Alzheimer’s. One will experience symptoms such as confusion, mild memory loss, and speaking issues. The inheritance pattern of early-onset Alzheimer’s is autosomal dominant inheritance. This means that if you inherit the abnormal Alzheimer’s gene from a parent, you are likely to get the disease. Even though Alzheimer’s is a somewhat common disorder, the inheritance pattern of late-onset Alzheimer’s is still unknown. Although, scientists believe genetic, environmental, and lifestyle factors play a role in a person’s risk for developing the disease.

The biological field is in constant investigation and there are new findings all the time. Science is so exciting that writers, educators and publishers want to make it available and understandable to everyone. Being this the case, people generate easy accessible websites with the intention to inspire others to acquire knowledge of what’s new in science, so they include the new findings, most of the time from journal reports of PhD students or a team of researchers have done. An example of these types of websites is “iflscience.com,” where I found an article called “Destruction of Brain Cell Connections May Be the Earliest Indicator of Alzheimer’s” about a new discover that could help in the

2010). The neuroinflammation is an early, non-specific immune reaction to tissue damage or pathogen invasion (Lee et al. 2010). Inflammation of the central nervous system (CNS) is characterized by increased glial activation, pro-inflammatory cytokine concentration, blood-brain-barrier permeability, and leukocyte invasion (Lee et al. 2010). Microglia are cells that support and protect neuronal functions (Lee at al. 2010). They act as the first and main form of active immune defense that orchestrate the endogenous immune response of the Central Nervous System. The microglia play a central role in the cellular response to pathological lesions such as Aβ. Aβ can attract and activate microglia, leading to clustering of microglia around Aβ deposits sites in the brain (Lee et al. 2010). Even though microglia have neuroprotective functions, neurotoxic mechanisms which involves continuous activation of microglia and toxic factors are released by microglia, which may lead to neuroinflammation (Lee et al. 2010). Astrocytes (star-shaped glial cells) are the most abundant cells in the brain and are located in the brain and spinal. Astrocytes have various functions such as: biochemical support of endothelial cells of the BBB, supplying nutrients to the nervous tissue, maintenance of extracellular ion balance, and healing the brain and spinal cord following traumatic injury (Lee et al., 2010). Chemokines are released by astrocytes which attract microglia and they further express proinflammatory products, thus increasing neuronal damage in the pathogenesis of AD (Lee et al., 2010). Astrocytes play a critical role in Aß clearance and degradation, and they also provide trophic support to neurons forming a protective barrier between Aß deposits and neurons (Wyss-Coray et al., 2003). Neurons contribute to the production of

Furthermore, inflammation is linked with bipolar disorder and can explain some of the comorbidities such as diabetes, heart disease, and obesity, that result in decreased life expectancy. Inflammatory molecules are produced in the periphery by immune cells such as helper T cells and macrophages, in response to pathogens or cell damage. The proinflammatory molecules produced in the body can stimulate the microglia and other neuroimmune cells, by entering the brain through regions where the blood brain barrier (BBB) is more permeable, by active transport through the endothelial cells that make up the BBB, or by vagal nerve signalling (Muneer). The presence of inflammatory molecules in the brain stimulates the microglia to release

Political Media organizations are obligated to sufficiently inform the American public about both global and domestic political issues. News corporations are failing to completely deliver on that obligation as a result of increasing political polarization and decreasing quality of content fueled by social media. In order to deliver the American people with unbiased facts about our government, there needs to be a reduction in the partisanship of news outlets.

Alzheimer’s disease (AD) and Parkinson’s disease (PD) are the most widespread age-related neurodegenerative diseases. Both diseases impact a considerable number of people, where AD occurs in around 10 percent of the population greater than the age of 65 while PD occurs in roughly 1 percent of the population above the age of 65. AD is considered to be the most widespread cause of dementia, characterised by the progressive memory and cognitive deficits which impair ones day to day activities. The pathological hallmark of AD comprises of extracellular accumulation of senile plaques consisting of mainly amyloid-beta (Aβ) peptides, along with neurofibrillary tangles which are composed of the phosphorylated tau protein, located in the hippocampus and cortex. Conversely, PD is considered to be the most widespread movement disorder that is characterised by symptoms such as rigidity slow movements, resting tremor and other instabilities. The extreme loss of dopaminergic neurones in the substantia nigra is what defines PD, as the loss of this nerve cell can be linked to Lewy bodies containing aggregates of a soluble protein called α-synuclein.

Alzheimer’s disease is a progressive decline in cognitive function. It affects the brain by damaging brain cells resulting in a decreased in cognitive function, physical mobility, swallowing and fine motor skills. This disease approximately 5.1 million Americans aged sixty-five or older (Alzheimer 's Association, 2015) of which approximately 700,000 will likely die this year (Alzheimer 's Association, 2015) of related symptoms such as aspiration pneumonia due to decreased swallowing ability. The progression of this disease is consistent and cannot be cured or slowed (Alzheimer 's Association, 2015). According to the Alzheimer’s Association, Alzheimer’s is one of the most expensive chronic disease in the United States estimating a cost of 226 billion dollars per year (Alzheimer 's Association, 2015). This debilitating disease is the sixth leading cause of death in the United States (Alzheimer 's Association, 2015).

Within the last century, and even merely in the past decade, incredible advancements in technology have allowed modern medicine to rapidly progress to extraordinary levels, leaving scientists with unprecedented understanding of the human body, and of the aging process especially. While the field of gerontology has flourished as a result and knowledge of physiological changes in the aging body increased, scientists still only have a some-what fundamental understanding of the normal aging brain, and even less of abnormal age-related changes in the brain.

Alzheimer’s is a disease that affects from up to 60 – 80% of Dementia patients. It damages parts of your brain that effects your memory and more. Alzheimer’s can affect people of any age, but the age category that it mainly effects are people in their 60’s +. There are two types of Alzheimer’s diseases, familial and sporadic. Familial Alzheimer’s is a genetic type of Alzheimer’s that develops in people around the age of 40-55. Sporadic Alzheimer’s occurs after the age of 65 and is the most common type of Alzheimer’s.

Psychology is an applied as well as an academic field that studies both the human mind and behavior. The research in psychology attempts to explain and understand behavior, emotion and thought. The subject of psychology was created when Wilhelm Wundt opened up the very first psychology lab in Leipzig, Germany. Wilhelm Wundt believed that individuals who are appropriately trained would most likely be able to recognize the mental processes that are accompanied with feelings, thoughts and sensations (Wagner , 2009).

Aging is simply the procedure of growing old. Ironically, the process is not that simple. With enhanced medicinal attention and living circumstances in developed nations have improved both healthiness and life expectation, from approximately 50 years in the early 1900s to over 80 years at the current time. Nevertheless, age is the foremost risk factor for the primary devastating and life-threatening conditions such as diseases related to loss of neurologic functions, cancer, and heart and blood vessels.
