    The PK is a not empty set of attributes (or columns). The same format applies to the foreign key (abbreviated FK) because each FK matches a preexistent PK. Each of attributes being part of a PK (or of a FK) must have data values (such as numbers, letters or typographic symbols) but not data marks (also known as NULL marks in SQL world).

  3. Estradiol valerate - Wikipedia

    en.wikipedia.org/wiki/Estradiol_valerate

    A review of selected studies reported a range of mean peak estradiol levels of 24 to 140 pg/mL occurring 1 to 12 hours after administration of 2 mg oral estradiol valerate. [4] A study found that, in accordance with their differences in molecular weights, oral estradiol produced higher levels of estradiol than oral estradiol valerate. [109]

    [199] [200] In a study of topical application of hydrocortisone solution in men, skin permeability (defined as total radiolabeled urinary excretion) relative to the forearm (1.0) was 42.0 for the scrotum, 13.0 for the jaw angle, 6.0 for the forehead, 3.6 for the underarm, 3.5 for the scalp, 1.7 for the back, 0.8 for the palm of the hand, 0.4 ...

    The simplest PK compartmental model is the one-compartmental PK model. This models an organism as one homogenous compartment. This monocompartmental model presupposes that blood plasma concentrations of the drug are the only information needed to determine the drug's concentration in other fluids and tissues.

  8. Pyruvate kinase - Wikipedia

    en.wikipedia.org/wiki/Pyruvate_kinase

    Four isozymes of pyruvate kinase expressed in vertebrates: L (liver), R (erythrocytes), M1 (muscle and brain) and M2 (early fetal tissue and most adult tissues). The L and R isozymes are expressed by the gene PKLR, whereas the M1 and M2 isozymes are expressed by the gene PKM2. The R and L isozymes differ from M1 and M2 in that they are ...
