CT Values are an important part of calculating disinfectant dosage for the chlorination of drinking water. A CT value is the product of the concentration of a disinfectant (e.g. free chlorine) and the contact time with the water being disinfected.
Two criteria to determine the C q are used by different thermocyclers: threshold cycle (C t) is the number of cycles required for the fluorescent signal to cross a given value threshold. Usually, the threshold is set above the baseline, about 10 times the standard deviation of the noise of the baseline, [ 1 ] to avoid random effects on the C t .
A[CT]N{A}YR. In this notation, A means that an A is always found in that position; [CT] stands for either C or T; N stands for any base; and {A} means any base except A. Y represents any pyrimidine, and R indicates any purine. In this example, the notation [CT] does not give any indication of the relative frequency of C or T occurring at that ...
In the example above, the three genotypes would be CC, CT and TT. Other types of genetic marker , such as microsatellites , can have more than two alleles, and thus many different genotypes. Penetrance is the proportion of individuals showing a specified genotype in their phenotype under a given set of environmental conditions.
The Hounsfield unit (HU) scale is a linear transformation of the original linear attenuation coefficient measurement into one in which the radiodensity of distilled water at standard pressure and temperature is defined as 0 Hounsfield units (HU), while the radiodensity of air at STP is defined as −1000 HU.
CT scan or X-ray computed tomography, a medical imaging method; Calcitonin (symbol CT), a hormone produced in the thyroid gland; Calibrated automated thrombogram (CT or CAT), a coagulation test; Cardiothoracic surgery, the field of medicine specializing in chest surgery; Chemotype (ct.), a chemically distinct entity in a plant or microorganism
An illustration depicting primary tumor (in the form of tumor microenvironment) and the circulating tumor cells. A circulating tumor cell (CTC) is a cancer cell from a primary tumor that has shed into the blood of the circulatory system, or the lymph of the lymphatic system. [1]
The C 0 t value is the product of C 0 (the initial concentration of DNA), t (time in seconds), and a constant that depends on the concentration of cations in the buffer. Repetitive DNA will renature at low C 0 t values, while complex and unique DNA sequences will renature at high C 0 t values.
