Stem Cell Doping
Stem cell doping is the postulated practice of enhancing athletic performance through various beneficial effects of stem cells injected into the bloodstream or otherwise introduced into the body. Currently there are no documented cases of stem cell doping, but there are suspicions that the practice may already be emerging.

Stem Cells
In multicellular organisms, stem cells are undifferentiated or partially differentiated cells that can differentiate into various types of cells and proliferate indefinitely to produce more of the same stem cell. They are the earliest type of cell in a cell lineage. They are found in both embryonic and adult organisms, but they have slightly different properties in each. They are usually distinguished from progenitor cells, which cannot divide indefinitely, and precursor or blast cells, which are usually committed to differentiating into one cell type. In mammals, roughly 50–150 cells make up the inner cell mass during the blastocyst stage of embryonic development, around days 5–14. These have stem-cell capability. ''In vivo'', they eventually differentiate into all of the body's cell types (making them pluripotent). This process starts with the differentiation into the three germ layers – the ectoderm, mesoderm and endoderm – at the gastrulation stage. However, when ...

Agence France-Presse
Agence France-Presse (AFP) is a French international news agency headquartered in Paris, France. Founded in 1835 as Havas, it is the world's oldest news agency. AFP has regional headquarters in Nicosia, Montevideo, Hong Kong and Washington, D.C., and news bureaus in 151 countries in 201 locations. AFP transmits stories, videos, photos and graphics in French, English, Arabic, Portuguese, Spanish, and German. History Agence France-Presse has its origins in the Agence Havas, founded in 1835 in Paris by Charles-Louis Havas, making it the world's oldest news service. The agency pioneered the collection and dissemination of news as a commodity, and had established itself as a fully global concern by the late 19th century. Two Havas employees, Paul Julius Reuter and Bernhard Wolff, set up their own news agencies in London and Berlin respectively. In 1940, when German forces occupied France during World War II, the news agency was taken over by the authorities and renamed "Office fr ...

Doping In Sport
In competitive sports, doping is the use of banned athletic performance-enhancing drugs by athletic competitors as a way of cheating in sports. The term ''doping'' is widely used by organizations that regulate sporting competitions. The use of drugs to enhance performance is considered unethical, and therefore prohibited, by most international sports organizations, including the International Olympic Committee. Furthermore, athletes (or athletic programs) taking explicit measures to evade detection exacerbate the ethical violation with overt deception and cheating. The origins of doping in sports go back to the very creation of sport itself. From ancient usage of substances in chariot racing to more recent controversies in doping in baseball, doping in tennis, doping at the Olympic Games, and doping at the Tour de France, popular views among athletes have varied widely from country to country over the years. The general trend among authorities and sporting organizations over the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gene Doping
Gene doping is the hypothetical non-therapeutic use of gene therapy by athletes in order to improve their performance in those sporting events which prohibit such applications of genetic modification technology, and for reasons other than the treatment of disease. , there is no evidence that gene doping has been used for athletic performance-enhancement in any sporting events. Gene doping would involve the use of gene transfer to increase or decrease gene expression and protein biosynthesis of a specific human protein; this could be done by directly injecting the gene carrier into the person, or by taking cells from the person, transfecting the cells, and administering the cells back to the person. The historical development of interest in gene doping by athletes and concern about the risks of gene doping and how to detect it moved in parallel with the development of the field of gene therapy, especially with the publication in 1998 of work on a transgenic mouse overexpressing insul ...

Doping At The Olympic Games
This article is about the history of competitors at the Olympic Games using banned ergogenic aid, athletic performance-enhancing drugs. History The use of performance-enhancing tactics or more formally known as PEDs, and more broadly, the use of any external device to nefariously influence the outcome of a sporting event has been a part of the Olympics since its inception in Ancient Greece. One speculation as to why men were required to compete naked was to prevent the use of extra accoutrements and to keep women from competing in events specifically designed for men. Athletes were also known to drink "magic" potions and eat exotic meats in the hopes of giving them an athletic edge on their competition. If they were caught cheating, their likenesses were often engraved into stone and placed in a pathway that led to the Olympic stadium. In the modern Olympic era, chemically enhancing one's performance has evolved into a sophisticated science, but in the early years of the Mode ...

Bioethics
Bioethics is both a field of study and professional practice, interested in ethical issues related to health (primarily focused on the human, but also increasingly includes animal ethics), including those emerging from advances in biology, medicine and technologies. It proposes the discussion about moral discernment in society (what decisions are "good" or "bad" and why) and it is often related to medical policy and practice, but also to broader questions as environment, well-being and public health. Bioethics is concerned with the ethical questions that arise in the relationships among life sciences, biotechnology, medicine, politics, law, theology and philosophy. It includes the study of values relating to primary care, other branches of medicine ( "the ethics of the ordinary"), ethical education in science, animal, and environmental ethics, and public health. Etymology The term ''Bioethics'' (Greek , life; , behavior) was coined in 1927 by Fritz Jahr in an article about a "b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
