"Christopher Wanjek uses a take-no-prisoners approach in debunking the outrageous nonsense being heaped on a gullible public in the name of science and medicine. Wanjek writes with clarity, humor, and humanity, and simultaneously informs and entertains." -Dr. Michael Shermer, Publisher, Skeptic magazine; monthly columnist, Scientific American; author of Why People Believe Weird Things Prehistoric humans believed cedar ashes and incantations could cure a head injury. Ancient Egyptians believed the heart was the center of thought, the liver produced blood, and the brain cooled the body. The ancient Greek physician Hippocrates was a big fan of bloodletting. Today, we are still plagued by countless medical myths and misconceptions. Bad Medicine sets the record straight by debunking widely held yet incorrect notions of how the body works, from cold cures to vaccination fears. Clear, accessible, and highly entertaining, Bad Medicine dispels such medical convictions as: * You only use 10% of your brain: CAT, PET, and MRI scans all prove that there are no inactive regions of the brain . . . not even during sleep. * Sitting too close to the TV causes nearsightedness: Your mother was wrong. Most likely, an already nearsighted child sits close to see better. * Eating junk food will make your face break out: Acne is caused by dead skin cells, hormones, and bacteria, not from a pizza with everything on it. * If you don't dress warmly, you'll catch a cold: Cold viruses are the true and only cause of colds. Protect yourself and the ones you love from bad medicine-the brain you save may be your own.

Unique in its review of modern analytical approaches to vitamin fortification, this book emphasizes fast, sensitive, and accurate methods, along with assays enabling the detection of various isomers and multiple vitamins. The expert contributors describe the concepts as well as analytical and assay methods to study fortification, along with applications to create better and safer foods. Taking into considerations regulatory matters, they include data on sampling and extraction methods, and discuss the various pros and cons of each. As a result, readers are able to determine, which type of analytical method is best suited for added vitamins. A practical guide for food chemists and technologists, as well as analytical laboratories and biochemists.

Proteins Biochemistry and Biotechnology 2e is a definitive source of information for all those interested in protein science, and particularly the commercial production and isolation of specific proteins, and their subsequent utilization for applied purposes in industry and medicine. Fully updated throughout with new or fundamentally revised sections on proteomics as, bioinformatics, protein glycosylation and engineering, well as sections detailing advances in upstream processing and newer protein applications such as enzyme-based biofuel production this new edition has an increased focus on biochemistry to ensure the balance between biochemisty and biotechnology, enhanced with numerous case studies. This second edition is an invaluable text for undergraduates of biochemistry and biotechnology but will also be relevant to students of microbiology, molecular biology, bioinformatics and any branch of the biomedical sciences who require a broad overview of the various medical, diagnostic and industrial uses of proteins. • Provides a comprehensive overview of all aspects of protein biochemisty and protein biotechnology • Includes numerous case studies • Increased focus on protein biochemistry to ensure balance between biochemisty and biotechnology • Includes new section focusing on proteomics as well as sections detailing protein function and enzyme-based biofuel production "With the potential of a standard reference source on the topic, any molecular biotechnologist will profit greatly from having this excellent book. « (Engineering in Life Sciences, 2004; Vol 5; No. 5) “Few texts would be considered competitors, and none compare favorably.» (Biochemistry and Molecular Education, July/August 2002) «…The book is well written, making it informative and easy to read…» (The Biochemist, June 2002)

Designed as a research-level guide to current strategies and methods of membrane protein production on the small to intermediate scale, this practice-oriented book provides detailed, step-by-step laboratory protocols as well as an explanation of the principles behind each method, together with a discussion of its relative advantages and disadvantages. Following an introductory section on current challenges in membrane protein production, the book goes on to look at expression systems, emerging methods and approaches, and protein specific considerations. Case studies illustrate how to select or sample the optimal production system for any desired membrane protein, saving both time and money on the laboratory as well as the technical production scale. Unique in its coverage of «difficult» proteins with large membrane-embedded domains, proteins from extremophiles, peripheral membrane proteins, and protein fragments.
