Nischal K. Karki William Carey University BIO 470 Cell Physiology Dr. Douglas Lipka Abstract Dynein is an ATPase from ATP associated with various cell activities family. Cytoplasmic dynein transports various materials from outside the cell to the center body. It is one of the few proteins that can convert the chemical energy of ATP into mechanical. It is a massive macro molecule that is involved with the movement of various organelles within the cell. It is also involved with the movement

transmissible spongiform encephalopathy (TSE). Prions are caused by the abnormal structure and folding of prion proteins in the brain. The abnormality rapidly spreads from protein to protein‚ causing the patient to experience brain damage and neurodegeneration. Due to the relatively new discovery of prions‚ not much else is known about them. CJD is seen around the world‚ but most commonly in American and Europe. The current number of people infected could be anywhere from 7‚600 to 22‚800‚ but due

In humans‚ MPS II can be expressed in a mild‚ intermediate‚ or severe form based on clinical signs with equivocally levels of enzyme in each form. The severe form occurs in children and results in skeletal deformities and neurodegeneration. The mild form occurs in adults and has a slower less debilitating course with preservation of intelligence. The clinical progression and biochemical characteristics of the enzyme defect in this dog best correlate with the intermediate form

PD is a degenerative disorder characterized by shaking‚ stiffness‚ slow movements and difficulty of balance while AD is a gradual process of neurodegeneration whereby the nerve connections in the brain erode slowly. One of the hallmarks for AD is the Tau protein whereby it kick starts a cascade that eventually leads to the disease. Caffeinated coffee has a positive impact on these symptoms and mechanism

Biotechnology (sometimes shortened to "biotech") is a field of applied biology that involves the use of living organisms and bioprocesses in engineering‚ technology‚ medicine and other fields requiring bioproducts. Biotechnology also utilizes these products for manufacturing purpose. Modern use of similar terms includes genetic engineering as well as cell and tissue culture technologies. The concept encompasses a wide range of procedures (and history) for modifying living organisms according to human

Post-traumatic stress disorder‚ or PTSD‚ is an often talked-about problem among war news and catastrophic events. It’s a household word and a well-known phrase. Post-traumatic stress disorder is a common brain affliction‚ with many causes. Research about its effects on the brain and brain chemistry are still going on‚ and treatments are still being tested. Post-traumatic stress disorder affects multiple areas of the brain‚ and that‚ in turn‚ affects an individual’s ability to function. Learning about
