Topic: Contamination

  Contamination in Sequence Databases
Screens for vector contamination may also be conducted by running a sequence similarity search, such as BLAST, against other vector sequence databases, for example NCBI's vector database, or the EMVEC vector database from the European Bioinformatics Institute (EBI).
The ability to detect vector contamination using this approach alone is limited, however, because it is hard to distinguish between a single cloning site and a naturally occurring restriction site, and because the cloning process does not always recreate the sites used for cloning.
VecScreen can be used to detect contamination with many of the adapters, linkers, and PCR primers used in the most popular cDNA cloning strategies because the UniVec database includes the sequences for such oligonucleotides.

  Seed Contamination by Genetically Engineered DNA
This report, Gone to Seed: Transgenic Contaminants in the Traditional Seed Supply, presents the results of a pilot study UCS conducted to determine whether transgenic (genetically modified) DNA sequences from biotechnology crops adopted by the United States during the last decade could be detected in traditional (nonmodified) varieties of seeds.
The pilot study is too limited to support quantitative estimates of overall contamination levels in seeds of traditional crop varieties, but the available data suggest that roughly 0.05 to 1 percent of these seeds are contaminated with transgenic sequences.
contaminated corn seeds that would have been planted in fields of traditional corn varieties if the seed supply were contaminated at a one percent rate.

 OCD and Contamination
One particularly unusual aspect of contaminating substances is the extent to which tiny amounts of them are often believed to cover very large areas.
When contaminated, they can move freely about their dirty world and touch and do anything, since everything in it is already contaminated.
To further complicate our contamination picture, there is a variant that veers off into what is known as "hyperresponsibility." This is where instead of being fearful of becoming contaminated, sufferers fear spreading contamination to others.

 Newhall Remediation Project - Understanding Contamination
Often contaminants in the soil are attached to soil particles (or grains).
In these cases, contaminants are reduced to non-harmful concentrations by natural biological, chemical, and physical processes before the contamination reaches the surface or flows to lakes or rivers.
Exposure to airborne contamination by Newhall residents is only likely to occur if residents dig up contaminated soil from their yards, (download Hamden Vegetable Uptake Fact Sheet)leaving it exposed to the air where dust can be generated.

 GM Contamination Register
Contaminated foods found in the UK, France and Germany.
This GM contamination register is the first of its kind in the world.
Because of this failure of national and international agencies, GeneWatch UK and Greenpeace International have launched this joint initiative to record all incidents of contamination arising from the intentional or accidental release of genetically modified (GM) organisms (which are also known as genetically engineered (GE) organisms).

 Contamination (1980)
He owns a very old copy of this movie that was not called "Contamination" but called "Alien Contamination".
So, he let me borrow this flick one night and I was rather disappointed at first.
Many people call this movie another "Alien" ripoff, but this movie is not anything like it.
