25. Medical Biotechnology: Part Ib. Stem Cells-Therapy and Medical Research NQ
Stem cell research has created national, if not global controversy. Why? What divides our thinking about stem cell research? This section provides the basics on stem cell research including: embryonic stem cells; adult stem cells; and, induced pluri-potent stem cells. Also discussed are their potential therapeutic application for degenerative diseases.From:Albert KauschViews:1 0ratingsTime:36:03More inScience Technology

26. Medical Biotechnology: Part Ic. Animal and Human Cloning and Genetic Engineering NQ
Some of the same techniques described for stem cell research, have been extended and applied to animal cloning, creating part of the controversies surrounding both topics. What is cloning? Cloning an organism (as a totally different process distinguished from cloning a gene) is a process whereby all members are directly descended, asexually, from a single organism by......various ways, as we show in this section, and this demonstrates that all the information required for an organism and its development are in the a single cell. many animals have now been cloned, including, sheep (Dolly), cattle, pigs, mice, rats, fish, dogs, cats, horses, mules, and more recently monkeys. Can humans be cloned? Probably.From:Albert KauschViews:0 0ratingsTime:25:37More inScience Technology

21. Pharmaceutical Biotechnology: Part Ib Emergent Technologies DNA-based Biotechnology NQ
With Recombinant DNA Drug development pharmaceutical biotechnology embraces the tools of genetic modification for new therapies. Similar to the technology introduced in the Agricultural Biotechnology section of this course, gene constructs can be made using DNA from different sources to make high value proteins that can be produced as injectable drugs. Insulin was one of the first recombinant DNA drugs to be made this way. Notice that recombinant insulin does not draw nearly the controversy as genetically modified tomatoes (even though they use the same technology). in this part we also examine the use of this technology for antibody based drugs and new vaccines.From:Albert KauschViews:0 0ratingsTime:58:56More inScience Technology

27 . Medical Biotechnology: Part II. Gene Therapy, Tissue Engineering and Nanotechnology
In theory, gene therapy offers a straight forward to the molecular treatment of various diseases, by using genes to prevent or treat disease by: Replacing a mutated gene(s) with a healthy copy; Inactivating/knocking out a mutated gene; or, Introducing new gene. Gene Therapy offers an approach to treating disease by either modifying the expressions of an individual #39;s genes or correction of abnormal genes. While this seems straight forward (ie replace or supply a healthy insulin gene in pancreatic cells of a diabetic) it has been difficult to actualize. Think here also about dual use problems (ie genetic doping for athletes, genetic modification enhancement for military personnel, and germline genetic engineering of humans with heritable genes). in this section we also review tissue engineering and some of the possibilities for nanotechnologies in medical devices.

28 . Medical Biotechnology:Biotechnology Applications in Tough Times. Part IIIa. Pandemic Flu NQ
An influenza pandemic is a global outbreak of disease that occurs when a new influenza A virus appears or "emerges" in the human population, causes serious illness, and then spreads easily from person to person worldwide. Is a worldwide outbreak of influenza possible? Probable is what experts would call it. Is the film Contagion science fiction? or a documentary on something that hasn #39;t happened yet? How accurate is it? How worried should we be? This lecture looks at a pandemic as a matter of time and puts current research into a biotechnology perspective.From:Albert KauschViews:0 0ratingsTime:01:10:53More inScience Technology

29. Medical Biotechnology:Biotechnology Applications in Tough Times. Part IIIb. Bioweapons NQ
Bioterrorism is the deliberate use of microbial agents and toxins as weapons. prior to 9/11 bioweapons were not considered a (very) serious threat, but now we realize the insidious possibility of human suicide delivery agents. Infected humans could act as dispersal genets for diseases that would otherwise be difficult to weaponize. In addition the applications of biotechnology and synthetic biology make these types of weapons cheaper and faster to manufacture that atomic weapons. This lecture review the top six most probable bioweapons and some of the possibilities for synthetic weapons in the future.From:Albert KauschViews:0 0ratingsTime:01:15:36More inScience Technology
