Medical laboratory scientists

One decade ago the term atomic absorption spectroscopy was familiar to only a small group of scientists, to a few chemists working on special problems, and to astrophysicists. Within the last few years, however, this analytical tedinique has found enthusiastic acceptance by science and industry. Several hundred papers have been published in a short time on basic research, instrumentation, development of methods, and practical application of atomic absorption spectroscopy. Several good reviews of the subject stressing various aspects have appeared (A13, D6, E2, G6, L3, L8, M6, M7, R2, R5, W15), and it seems hardly necessary to add to their number. The problems of medical laboratories and clinical... 

Clinical chemistry now encompasses aspects of analytical chemistry, biochemistry, clinical laboratory science, toxicology, immunology, and molecular biology. Our intended readership includes the clinical laboratory scientists, practioners of the medical arts, medical technologists, and associated disciplines. 

Over the next 30 years, Patterson used mass spectroscopy and clean laboratory techniques to demonstrate the pervasiveness of lead pollution. He traced the relationships between America s gas pump and its tuna sandwiches, between Roman slaves and silver dimes, and between Native American Indians and polar snows. He forged as close a connection between science and public policy as any physical scientist outside of medical research. He made the study of global pollution a quantitative science. And marrying his stubborn determination to his passionate conviction that science ought to serve society, Patterson never budged an inch. 

Boston University Medical Center BSL-4 Containment Laboratory had already contaminated three scientists before they even got funded. This incident brought up again the... 

The potential contribution of stem cells to medical treatment lies in then-capability to differentiate and grow into normal, healthy cells. Using pluripotent stem cells, scientists are devising means to culture them in the laboratories and coax them to grow into various specialized cells. Rather than gene therapy, with stem cells we have the potential of cell therapy to repair our diseased tissues and organs. This will circumvent the lack of donor organs. Stem cells also provide the possibility for healthy cells to cure disabilities such as strokes, Parkinson s disease, and diabetes. 

Scientists at the Harvard Medical School have prepared a recombinant form of a receptor. The idea is to use this cloned receptor as a decoy and mop up the anthrax molecules in circulation. This has been confirmed in laboratory experiments, but ongoing studies are needed. 

Van M. Sim, M.D. (1922-1990) Trained as an internist, he was Chief of Clinical Research from 195S1961 and Chief Scientist of the Medical Research Laboratories thereafter. 

This method of calculation is based on the use of animal toxicity data to determine limits. As mentioned earlier, this method is particularly suited for determining limits for materials that are not used medically. This method is based upon the concepts of acceptable daily intake (ADI) and no observed effect level (NOEL) developed by scientists in the Environmental Protection Agency [7], the U.S. Army Medical Bioengineering Research and Development Laboratory [8], and the toxicology department at Abbott Laboratories [9], This method has also been recently used to calculate the limits of organic solvent residues allowed in APIs [10].
