Medicine Tomorrow

Nanotechnology today has become an explosion of an evolution. In the last decade there have been remarkable advances field of nanotechnology. Many science fiction writers such as: Jules Verne, H.G. Wells, Arthurs C. Clarke, Frederik Pohl, Isaac Asimov, and Robert Heinlein, foresaw many of our current scientific achievements of today and tomorrow. The manufacture of atom sized mechanisms that can heal living cells and materials stronger and lighter than anything today has been dream of engineers and scientist alike. Many stories have been written about the good and evils of nanotechnology. Prey is a sci-fi story by Michael Crichton about nanotechnology how it could be abused if not monitored carefully. Sunscreens, water resistant clothing is all products of nanotechnology. Nanotechnology fields range from the miniaturization of semiconductor devices, to atom manipulation, in fields of chemistry, mechanic, life science and electronics as illustrated on slide 2. The breakdown of na...

     HIV/AIDS pandemic is having a world impact on the health and welfare of everyone. All of the global countries from South African countries, such as in Botswana, in Russia, in China and in the United States have to deal with disease and its economic impact on society. AIDS has swept the areas of Africa due to the pronounced homosexual activity in the sub-Saharan Africa. Due to the extremely poor living conditions and lack of proper medical or education, these areas are more prone to the disease. Areas of Kenya and Nairobi have found entire families to have AIDS. Entire regions of the Sub-Saharan belt are infected with AIDS.   The people in the region have to be isolated from the productive members of society. They people in the region are superstitious and will not trade or interact with the people who have AIDS. Those people become isolated without the ability to work and provide income for their families. The problem is many of the people in the regio...

      Stem cells are undifferentiated biological cells that can differentiate into specialized cells and can divide (through mitosis ) to produce more stem cells. They are found in multicellular organisms . In mammals , there are two broad types of stem cells: embryonic stem cells , which are isolated from the inner cell mass of blastocysts , and adult stem cells , which are found in various tissues. In adult organisms, stem cells and progenitor cells act as a repair system for the body, replenishing adult tissues. In a developing embryo, stem cells can differentiate into all the specialized cells—ectoderm, endoderm and mesoderm (see induced pluripotent stem cells )—but also maintain the normal turnover of regenerative organs, such as blood, skin, or intestinal tissues. There are three accessible sources of autologous adult stem cells in humans: Bone marrow, which requires extraction by harvesting , that is, drilling into bone (typically t...
