Amyotrophic Lateral Sclerosis James Smith University of Southern Mississippi Dr. Jennifer Walker BSC 370 Genetics‚ Spring 2010 Imagine being not able to move your muscles freely everyday‚ and that process has to coordinate between the brain and the spinal cord to tell the muscles to move. However‚ when this coordination is challenged and can not convey signals‚ the results are no muscle movement. At first‚ muscles in the hands‚ arms‚ and legs feel weak. The hands and feet twitch

predisposition to drug hypersensitivity reactions‚ which are strongly associated with the major histocompatibility complex. (11) The pathogenesis of SJS/TEN is not fully understood. But it is believed to be immune-mediated‚ furthermore‚ keratinocyte apoptosis followed by necrosis is the pathogenic basis of the widespread epidermal detachment observed in SJS/TEN. There are chances of death due to TEN which can be predicted by TEN-specific severity-of-illness score.(12) In the above-mentioned case‚ the

Crohn’s Disease Shauna Griffin Immunology Spring 2016 April 23‚ 2016 Dr. Turner Crohn’s disease‚ also known as Ileitis‚ is a chronic‚ inflammatory disease involving the gastrointestinal tract (GI tract). The main purpose of the GI tract is to break down food in order to allow the nutrients to be absorbed effectively. This is extremely important to the body’s functioning and overall performance. The GI tract is essential for energy‚ growth and repair and it is because of these reasons that Crohn’s

Cancer cells also have the unique quality of avoiding apoptosis‚ cell death‚ which allows for the continuation and growth of the cancer. Cancer will be a diagnosis received by an estimated 1.5 million people in the United States this year alone. 1500 cancer patients will die each day. The National Institute

nuclear factor-kappa B (NF-κB)‚ this is a regulatory molecule that controls nearly 200 genes of which that encode pro-inflammatory cytokines and cell adhesion molecules. The increase in synthesis of cytokines and other enzymes causes an increase in apoptosis of epithelial cells and fibroblasts. Signaling and amplification phase: One of the pro -inflammatory cytokines produced is tumor necrosis factor alpha (TNF-α)‚ this molecule damages the cells but also increases the activity of NF-κB.

Mitochondria are a key organelle responsible for aerobic respiration in eukaryotic cells. The majority of the energy that eukaryotes rely on is obtained through the use of mitochondria‚ thus emphasizing the importance of these dynamic organelles. Due to the importance in respiration mitochondria are found in high abundance in oxidative tissues such as heart‚ kidney‚ and the brain1‚2 3. Inner mitochondrial membrane plays host to a collection of enzyme complexes termed the electron transport chain
