...Additionally, nanoparticles are being used as a physical means of destroying tumorous tissue by the use of Magnetic Nanoparticle Hyperthermia. This technology uses the power of magnets to oscillate iron oxide magnetic nanoparticles to create heat in the form of kinetic energy and has shown to drastically reduce the size of brain tumors when compared to patients who have no treatment at all. Beyond their use as diagnostics and physical tools to destroy cancerous tumors, magnetic nanoparticles are also used as a delivery agent for gene therapy. For example, magnetic nanoparticles have shown to increase the half life of the various biological matter such as DNA and RNA so that it can reach the intended target before the body’s immune response destroys the magnetic gene delivery system. In the future, research will be focused on pharmacokinetics of the nanoparticles, ensuring the nanoparticles can stay in the body for longer periods of time and that the body reacts in a positive manner to the magnetic nanoparticles. Introduction Nanotechnology has been an emerging field recently due to its widespread capabilities. Nanotechnology has been applied in many fields of biomedicine due to its potential in controlling the delivery of drugs, providing greater contrast in magnetic resonance imaging, cell and tissue targeting, and hyperthermia; all of which can be used in cancer therapy (Mulens, del Puerto Morales and...

...2013 Approach to Care Cancer refers to disease processes involving an uncontrollable abnormal growth of cells in the body. The body is made up of many cells with numerous functions. The cells grow and divide in order for the human body to function adequately. When the cells get damage or become old they die off and are replaced by new ones. Cancer develops when the body’s normal control mechanism is no longer working. The old cells will not die and start to grow out of control, leading to formation of abnormal cells that develops into a mass of tissue known as tumors. Although, some cancers like leukemia do not form tumors ("CTCA," 2013).Cancer tumors are malignant and may invade surrounding tissues and organs. Cancer can also spread to distant organs in the body via the bloodstream and lymphatic system. In this paper, the writer will discuss the diagnosis and staging of cancer, complications of cancer, the side effects of treatmens, and methods to lessen physical and psychological effects of cancer and its treatments. To determine what causes cancer is very complex, but studies have suggested that the causes of cancer include, genetic risks, diet, lifestyle, tobacco use, and physical activity. Others causes are some infections, chemicals exposures and radiation ("American Cancer Society," 2013). Detecting cancer early is very crucial as it allows for early treatment and can stop the disease progression. Cancer causes many signs and symptoms depending on size, location of...

...induce the patient to a state of insensitivity, doctors would knock them unconscious with a blow to the jaw. By 1846, opium and alcohol were the only drugs able to diminish the pain. Now it being 169 years later, the discipline of anesthesia has expanded far beyond the operating room. There are better drugs, improved monitoring, and specialized training that have been responsible for growth in the general anesthesia field. They improve patient safety and comfort before and after surgery which is the goal of any physician in any specialty. Search Story My goal is to find the positive and negative effects of local, regional, and general anesthesia so that patients know what they are in for before they head into the operating room. I chose to research this topic because it really hits home for me. I have had three surgeries in my 18 years of living. The first procedure happened in 1998 when I was 9 months old, I clearly do not remember much, but I have heard countless stories from my family and the whole operation really took a toll on each of them individually. From what I have been ANESTHESIA 2 told, a couple months after being born, I had a staff infection on the left side of my neck. My parents took me to the doctor multiple times but nothing helped. Before we knew it, the small infection grew into a mass on my face. It looked like...
