Photodynamic Therapy (PDT) includes two steps of process. The first step is administration of a photosensitizer (PS) and the second step is activation by light lamination at an appropriate wave length to reactive the chemicals, causing them to emit free radicals and destroy the targeted abnormal cells.

    1. Kevorkian Pharmaceutical Institute has developed a cancer treatment that is extremely promising and profitable. The treatment involves “salting” cancerous tumors with tiny metallic particles, and then exposing them to high intensity radio waves that cause the metallic pellets to heat up and destroy the tumor without harming the healthy tissue. Although studies have been positive (95% of all cases), researchers have also noted an extremely adverse, and potentially lethal, side effect in 5% of patients tested, and they do not know why.…

    Photodynamic therapy (PDT) has been the standard treatment for PCV for years. Anti-vascular endothelial growth factor (Anti VEGF) agents (bevacizumab and ranibizumab) were introduced later on. Several studies reported better visual outcomes with anti-VEGF agents than with PDT. However, the rate for regression of polypoidal lesions was lower than that with PDT. So the optimal treatment for PCV is still controversial.…

    The use of sun protection has become a much more common topic of conversation among the general population over the last decade. This can be attributed to several different factors. In some instances, environmental concerns over depleting ozone and higher levels of radiation penetration are the cause. Another important reason is that well over half of all new cancers in the United States are skin cancers (Capelle, 2006, pg. 1). Ultra-violet (UV) light is the cause of these cancers. There are several types of UV light. According to Gonzaga sunlight is made up of a broad spectrum of light. This spectrum is divided by wavelength in UV light. There are three types of UV light; UVA, UVB, and UVC (Gonzaga, 2009, 19). UVC is almost completely absorbed by the ozone. UVA and UVB are the two types of UV light that penetrate and affect people. UVA penetrates deeper into the skin and can cause immediate darkening of pigments, there is increasing thought that UVA may have more to do with photodamage than thought previously (Gonzaga, 2009, 21). UVB light ranges from 290 mm to 320 mm and is carcinogenic. It does not penetrate as deeply into the skin as UVA, however it has several acute effects including…

    Radiation therapy is a therapeutic procedure that uses high energy waves to treat and kill cancer cells in the human body while attempting to avoid healthy cells that don’t need to be treated. The radiopharmaceuticals that are used work together to damage the cancerous tumors cell’s DNA. When those cells die, they are broken down and discarded using the body’s natural process. The therapy is usually given as a curate technique which means having hope to eliminate or prevent the reoccurrence of the cancer. There are side effects from radiation, but they differ in every patient as does the treatment…

    A mutation is a permanent change in the DNA sequence of a gene. Mutation rates are usually very low but there are factors that can increase the mutation rates. These factors are referred to as mutagens and conclude a range of physic-chemical agents. UV light is a mutagen that affects all living things and has an adverse effect on the replication process of DNA within cells(.Leonard,2002) In this experiment we examine the effects of UV light on the growth of different bacteria. Cells are exposed to this radiation for different time intervals to also examine the sensitivity of each cell to each light. The exercise answers questions as to why he lid on the petri dish was removed during exposure time an analyse whether the cells test were equally sensitive to UV light and we also explore the relationship UV has with the time of exposure. The bacteria exposed to UV light for longer would either multiply very insignificantly or not multiply at all and also the different bacteria species have different sensitivity levels to this kind of radiation. We can conclude or draw a hypothesis that UV light is a mutagen that inhibits the DNA replication process that gives rise to cell division thus cell growth or multiplication.…
