International unit. In pharmacology, the international unit ( IU) is a unit of measurement for the effect or biological activity of a substance, for the purpose of easier comparison across similar forms of substances. International units are used to quantify vitamins and biologics ( hormones, some medications, vaccines, blood products and ...
Virus quantification. Virus quantification is counting or calculating the number of virus particles (virions) in a sample to determine the virus concentration. It is used in both research and development (R&D) in academic and commercial laboratories as well as in production situations where the quantity of virus at various steps is an important ...
Enzyme unit. The enzyme unit, or international unit for enzyme (symbol U, sometimes also IU) is a unit of enzyme 's catalytic activity. [ 1] 1 U (μmol/min) is defined as the amount of the enzyme that catalyzes the conversion of one micro mole of substrate per minute under the specified conditions of the assay method. [ 2]
Homeopathic dilutions. In homeopathy, homeopathic dilution (known by practitioners as "dynamisation" or "potentisation") is a process in which a substance is diluted with alcohol or distilled water and then vigorously shaken in a process called "succussion". Insoluble solids, such as quartz and oyster shell, are diluted by grinding them with ...
A dosage of 1 mg/day oral estradiol valerate has been found to produce approximate circulating concentrations of 50 pg/mL estradiol and 160 pg/mL estrone, while a dosage of 2 mg/day results in circulating levels of 60 pg/mL estradiol and 300 pg/mL estrone. [108]
An equivalent (symbol: officially equiv; [ 1] unofficially but often Eq[ 2]) is the amount of a substance that reacts with (or is equivalent to) an arbitrary amount (typically one mole) of another substance in a given chemical reaction. It is an archaic quantity that was used in chemistry and the biological sciences (see Equivalent weight § In ...
The structures of solid magnesium citrates have been characterized by X-ray crystallography.In the 1:1 salt, only one carboxylate of citrate is deprotonated. It has the formula Mg(H 2 C 6 H 5 O 7) 2 The other form of magnesium citrate has the formula Mg(HC 6 H 5 O 7)(H 2 O) 2, consisting of the citrate dianion (both carboxylic acids are deprotonated). [1]
Certain lithium compounds, also known as lithium salts, are used as psychiatric medication, [ 4] primarily for bipolar disorder and for major depressive disorder. [ 4] Lithium is taken orally (by mouth). [ 4] Common side effects include increased urination, shakiness of the hands, and increased thirst. [ 4]
