Glossary Term
A family of probability density functions whose mean, median and mode are identical. The function generates a symmetrical curve, whose position and shape is determined by its location and scale parameters, the mean and standard deviation respectively. The standard normal distribution has a location parameter of 0 and a scale parameter of 1.
Tests
A measurement of Norovirus genogroup II.4 IgG antibody present in a sample.
Tests
A measurement of Norovirus genogroup II.4 IgM antibody present in a sample.
Tests
The determination of the norsertraline in a sample.
Indicators
This gene plays a role in cell-cell signaling.
Indicators
This gene plays a role in both intercellular signaling and cell fate determination.
Glossary Term
Any of various amplification and detection strategies applied to detection of virus contamination in donor blood. Specifically designed to detect recently infected individuals during the latency period before seroconversion.
Glossary Term
Laboratory procedure in which single stranded nucleic acids are allowed to interact so that complexes, or hybrids, are formed by molecules with sufficiently similar, complementary sequences. By this means the degree of sequence identity can be assessed and specific sequences detected. (From Biology-online)
Glossary Term
Nucleotide Excision Repair (NER) mends DNA regions that contain chemical adducts, such as UV-induced thymine dimers or carcinogenic adducts, which distort the DNA helix and interfere with replication and transcription. NER is targeted to actively transcribed regions of the genome. During NER in eukaryotes, shape irregularities are detected by protein complexes that slide along the DNA molecule and induce cuts on each side of a lesion several nucleotides away. Removal of the damaged 25-30 nucleotide fragment is followed by repair synthesis and ligation.
Glossary Term
A statistical method to test if observations are significant or due to chance. It proposes that no statistical significance exists in a set of given observations and attempts to show that no variation exists between variables or that a single variable is no different than its mean. It is presumed to be true until statistical evidence nullifies it for an alternative hypothesis.
Tests
A measurement of the blood in body products such as a urine or stool sample, not detectable on gross examination.
Glossary Term
The ratio of the odds of an event occurring in one group to the odds of it occurring in another group, or to a sample-based estimate of that ratio.
