The development of simple methods for generating molecular complexity with defined stereochemistry from easily accessible starting materials became significant and fascinating over last few decades. A simple methoxyphenol is found to be most appropriate precursor for generating wide range of complex cyclic and acyclic architectures. Several chemical1-5 and electrochemical methods6 have been used for the umpolung of electron-rich nucleophilic 2-methoxyphenols and 4-methoxyphenols to electrophilic…

Stephen Hawking, a brilliant man who lives with Lou Gehrig’s Disease. Born in Oxford, England on January 8th, 1942. Son of Frank Hawking and a philosophy .Isobel Hawking. Diagnosed at the age of 21 with ALS Stephen Hawking started to lose hope after 2 years of losing his nerves and being able to do daily functions of life, his symptoms started to slow down very drastically and steadied out for him and he took this as a sign to start his life up again. Soon meeting a women Jane Wilde, and…

A brain tumor is an abnormal growth of cells within the brain, which can be cancerous or non-cancerous (benign). It is generally caused by abnormal and uncontrolled cell division, normally either in the brain itself (neurons, glial cells (astrocytes, oligodendrocytes, ependymal cells), lymphatic blood vessels), in the cranial nerves (myelin-producing Schwann cells), in the brain envelopes (meninges), skull, pituitary and pineal gland, or spread from cancers primarily located in other organs…

are subjected to radioactive material on a daily basis. According to Cancer Risks among Radiologists and Radiologic Technologists: Review of Epidemiologic Studies “increased mortality due to leukemia among early workers employed before 1950, when radiation exposures were high” (Cancer Risks among Radiologists and Radiologic Technologists: Review of Epidemiologic Studies, N.A.) This shows the correlation between the workers employed in the early years and cancer, this means that people who…

detected using electronic devices. Important terms that will be discussed in this paper are ultraviolet light, photochromism, chemical reactions, and absolute zero. Relating to electromagnetic radiation having wavelengths shorter than those of visible light but longer than those of x-rays. Ultraviolet radiation is emitted by the sun and some of its absorbed by the sun and some of it is absorbed by the o-zone in the atmosphere. Too much exposure to ultraviolet light can be can lead to sun burn,…

Cancer is a group of diseases characterized by unregulated cell growth including the invasion and spread of mutated cells from the site of origin. Chemotherapy is a medicine which is used to kill cancer cells by damaging them so they can’t reproduce and spread. Chemotherapy also kills healthy living cells, which causes unwanted side effects such as hair loss, tiredness and pale skin. In this experiment we used MTT Assay to analyse which drug is more effective in killing cancer cells and keeps…

course of treatment (2). Radiation therapy involves exposure to normal tissues as well as the tumor tissue and can cause damage to the normal cells because of the high energy of the gamma and X-ray (1). All molecules in the cell including lipids, proteins, carbohydrates and nucleic acids have potential to receive damage by radiation. However, deoxyribonucleic acid (DNA) because of its function is the most important molecule in the cell which will be affected by ionizing radiation. Gamma and…

The question of whether cancer treatment, such as chemotherapy and radiation, is too harsh has been argued for many years by the general public, scientists and medical professionals. One side of the argument think that chemotherapy and radiation therapy are too harsh in the already stressful and painful process of having cancer. The other side thinks that chemotherapy and radiation are the best way to eliminate cancer cells from the body. Chemotherapy and radiotherapy are slightly different…

In the stages of prostate cancer (localized, regional and distant) both conventional and hadron radiation therapy have its benefits when compared to one another; but both offer a different form of treatment. Currently proton therapy is one of the most technologically advanced treatment for cancer. In proton therapy, protons are split form a hydrogen atom and accelerated to roughly two thirds the speed of light; transported along an evacuated tube into the treatment rooms. Then administered to…

transferred are called convection and conduction. Anything above -286 degrees Celsius gives off some amount of thermal energy, or infrared radiation. Half of the Sun’s energy is given off as infrared, and a good majority of the visible light gets absorbed, and then turned back into infrared radiation. Incandescent bulbs even give off 90% of their energy as IR radiation, and this is also true for toasters and other kitchen appliances. TV remotes use IR waves to send an invisible signal to the…
