  • Wake-Up Call

    Direct Answers - Column for the week of October 7, 2002

    In the first half of May, I went through two remarkable changes. One was physical and the other involved emotional recall.

    The physical one was what I thought was flu and a heavy dose of it. It was accompanied by a surreal shivering never experienced before or since. The recall was of a family I knew in my school days more than 20 years ago.

    I imagined them not during the school years, when I knew them, but much earlier. I got images of all three children as handsome creatures having just come into this world. I saw t ...

  • Diabetes--What You Need to Know About This Hidden Danger


    Diabetes is a disease in which blood glucose levels are above normal. Most of the food we eat is turned into glucose (sugar) for our bodies to burn to create energy. The pancreas, an organ that lies near the stomach, produces a hormone called insulin to help glucose get into the cells of our bodies. When you have diabetes, your body either doesn't make enough insulin or can't use its own insulin as well as it should. This causes large amounts of sugar to build up in your blood.

    The actual cause of diabetes continues to be a mystery, although both genetics and environmental facto ...

    Nucleoside derivatives as inhibitors of rna-dependent rna viral polymerase

    The present invention provides nucleoside compounds and certain derivatives thereof which are inhibitors of RNA-dependent RNA viral polymerase. These compounds are inhibitors of RNA-dependent RNA viral replication and are useful for the treatment of RNA-dependent RNA viral infection. They are particularly useful as inhibitors of hepatitis C virus (HCV) NS5B...


    Site-specific biotinylation of RNA molecules by transcription using unnatural base pairs.

    Publication Date: 2005 PMID: 16113238Authors: Moriyama, K. - Kimoto, M. - Mitsui, T. - Yokoyama, S. - Hirao, I.Journal: Nucleic Acids ResDirect site-specific biotinylation of RNA molecules was achieved by specific transcription mediated by unnatural base pairs. Unnatural base pairs between 2-amino-6-(2-thienyl)purine (denoted by s) and 2-oxo(1H)pyridine (denoted by y), or 2-amino-6-(2-thiazolyl)purine (denoted as v) and y specifically function in T7 transcription. Using these unnatural base pairs, the substrate of biotinylated-y (Bio-yTP) was selectively incorporated into RNA, opposite s or v in the DNA templates, by T7 RNA polymerase. This method was applied to the immobilization of an RNA aptamer on sensor chips, and the aptamer accurately recognized its target protein. This direct site-specific biotinylation will provide a tool for RNA-based biotechnologies.


    Arcturus Bioscience, Inc.: Novel Method for Gene Expression Profiling of Rat and Mouse Formalin-Fixed Paraffin-Embedded (FFPE) Tissues

    MOUNTAIN VIEW, CA (MARKET WIRE) Arcturus today announced a new application for gene expression profiling of rat and mouse tissues from FFPE samples using the Paradise(TM) Reagent System. Rat and mouse models are used in the discovery and development of potential drugs. Toxicological and disease effects are assessed using gene expression analysis of the animals' tissues. However, since these tissues are commonly preserved by FFPE, the extraction and isolation of RNA with


     
    		 
     


  • The Secret Spies Of The Future, The CIA In 2025, Sure They Look The Same?

    The CIA robotic spies will look like you and I, talk, walk, eat, act and even make mistakes like us. But these will not be living, breathing organic humans. The Labs around the country are working on them now, by 2025 they will be everywhere. It is time to a have a serious discussion on artificial intelligence and the future of clandestine spies using artificial intelligence robotics.

    Isaac Asimov had artificial organic robots in his books. We all saw the movie AI. Will we be fooled in the future by robots posing as people? Will we care? This might be a great opportunity for spying? C ...

  • Benefits of Green Tea
    Tea and Cancer Prevention
    Tea drinking is an ancient tradition dating back 5,000 years in China and India. Long regarded in those cultures as an aid to good health, researchers now are studying tea for possible use in the prevention and treatment of a variety of cancers. Investigators are especially interested in the antioxidants-called catechins-found in tea.

    1. What are antioxidants?

    The human body constantly produces unstable molecules called oxidants, also commonly referred to as free radicals. To become stable, oxidants steal electrons from other molecules and, in the p ...

  • Find a Doctor
    Find a Doctor
    This is usually a simple task. Open up your phone book (Yellow Pages) and look for one in your area; or ask your primary care physician for a referral to see a specialist. Better still, go online – there is an abundance of free
    directories listing doctors.

    How to find a doctor?
    There’s no magical route to finding the right doctor. If you have a primary care physician just call him or her and make an appointment. If you don’t have a primary care physician, try the route suggested above. Or, if you feel you need specialist care, you can save time and money by goin ...
