subtype

(programming)
If S is a subtype of T then an expression of type S may be used anywhere that one of type T can and an implicit type conversion will be applied to convert it to type T.

In object oriented programming, this means that objects of type S must accept every message that one of type T would.

Molecular subtypes were grouped as follows: luminal A subtype ([ER.sup.+] or [PR.sup.+], [HER2.sup.-] and Ki-67 index [percentage of [Ki-67.sup.+] tumor cells] < 15%); luminal B subtype ([ER.sup.+] or [PR.sup.+] and [HER2.sup.+], or Ki-67 index > 15%); HER2 subtype ([ER.sup.-] and [PR.sup.-], [HER2.sup.+]), basal-like subtype ([ER.sup.-], [PR.sup.-], and [HER2.sup.-]).
In a study published in the journal JCI Insight, researchers at the University of North Carolina reported that they have pinpointed a single molecule - microRNA-31 (miR-31) - the levels of which predict whether a patient has subtype 1 or subtype 2 of the disease.

Low-density lipoprotein cholesterol (LDL-C) is critical in the progression of atherosclerosis.[3],[4] It has been regarded as a preventive target in consensus guidelines (<1.8 mmol/L is the target).[5] The Global Assessment of Plaque Regression with a PCSK9 Antibody as Measured by Intravascular Ultrasound study showed that a lower level of LDL-C was correlated with greater regression of coronary plaque.[6] Comparison of the risk factors between the LAA and SVD subtypes showed that LDL-C was more strongly related to the LAA subtype.[7] Spence and Solo [8] have recently reported that some atherosclerosis plaques could be regressed by lowering LDL-C, but others could not be regressed by this method alone.
