  2. Assay - Wikipedia

    en.wikipedia.org/wiki/Assay

    An assay (analysis) is never an isolated process, as it must be accompanied with pre- and post-analytic procedures. Both the communication order (the request to perform an assay plus related information) and the handling of the specimen itself (the collecting, documenting, transporting, and processing done before beginning the assay) are pre-analytic steps.

    Mismatch repair is a highly conserved process from prokaryotes to eukaryotes.The first evidence for mismatch repair was obtained from S. pneumoniae (the hexA and hexB genes).

    Secondly, the laboratory supervisor, who reports to the laboratory director, is responsible for organizing regular training sessions on laboratory safety. [9] The third point, the personnel must be informed about any special hazards and be required to review the safety or operations manual and adhere to established practices and procedures. The ...

    U.S. Army Public Health Center Toxicology Lab technician assessing samples. Toxicology testing, also known as safety assessment, or toxicity testing, is the process of determining the degree to which a substance of interest negatively impacts the normal biological functions of an organism, given a certain exposure duration, route of exposure, and substance concentration.

  6. Sample ratio mismatch - Wikipedia

    en.wikipedia.org/wiki/Sample_ratio_mismatch

    Using Pearson's chi-squared goodness of fit test, we find a sample ratio mismatch with a p-value of 2.54 × 10-10. In other words, if the assignment of users were truly random, the probability that these treatment and control group sizes would occur by chance is 2.54 × 10 -10 .

  7. Bioassay - Wikipedia

    en.wikipedia.org/wiki/Bioassay

    A bioassay is a biochemical test to estimate the potency of a sample compound. Usually this potency can only be measured relative to a standard compound. [3] [1] A typical bioassay involves a stimulus (ex. drugs) applied to a subject (ex. animals, tissues, plants). The corresponding response (ex. death) of the subject is thereby triggered and ...

  8. Biocontainment - Wikipedia

    en.wikipedia.org/wiki/Biocontainment

    Primary containment requires using proper storage containers, good microbiological technique, and the use of appropriate safety equipment such as biological safety cabinets. Secondary containment is the protection of the environment external to the laboratory from exposure to infectious materials and is provided by a combination of facility ...

  9. Evolutionary mismatch - Wikipedia

    en.wikipedia.org/wiki/Evolutionary_mismatch

    Evolutionary mismatch (also "mismatch theory" or "evolutionary trap") is the evolutionary biology concept that a previously advantageous trait may become maladaptive due to change in the environment, especially when change is rapid. It is said this can take place in humans as well as other animals.
