They comprise three classes of cells, each unique as to structure and function, that are designated granulocytes, monocytes, and lymphocytes.
The Health Belief Model comprises two classes of variables: These are the readiness to get active and assumptions about the effectiveness of different measures.
This is achieved in humans by a motor pathway comprising two classes of neurons, termed upper motor neurons (UMNs) and lower motor neurons (LMNs).
Here we report the design, expression and characterization of a set of CXCL8 mutants comprising three classes of different engineering sites within the chemokine and their combination.
The HDAC family comprises four classes of deacetylases, grouped by their homology, their expression patterns and subcellular localisation, the cofactors required for their activity, and their substrates.
The Centers for Disease Control report comprises three classes of evidence: recommended strategies are based on strong rationale and suggestive evidence, suggested strategies may be supported by suggestive clinical or epidemiologic studies, and no recommendations are given for practices for which insufficient evidence or consensus regarding efficacy exists.
The school is composed by 5 grades, each of them comprising two classes, for a total of 10 classes.
The kDNA is comprised of two classes of circular DNA molecules that are catenated and compressed into a disc-like structure.
An important element of this model is the distinct action of dopamine on the direct and indirect pathways, comprised of two classes of striatal spiny projection output neurons that express different types of dopamine receptors, project to separate downstream targets, and regulate complementary aspects of motor behavior (Bateup et al., 2010; Kravitz et al., 2010; Cui et al., 2013).
