IC 50 values are typically expressed as molar concentration. IC 50 is commonly used as a measure of antagonist drug potency in pharmacological research. IC 50 is comparable to other measures of potency, such as EC 50 for excitatory drugs. EC 50 represents the dose or plasma concentration required for obtaining 50% of a maximum effect in vivo. [1]
Extracts of unripe fruit from Asian cultivars of Citrus aurantium (commonly known as "bitter" orange), collected in China, were reported to contain synephrine levels of about 0.1–0.3%, or ~1–3 mg/g; [10] Analysis of dried fruit of C. aurantium grown in Italy showed a concentration of synephrine of ~1 mg/g, with peel containing over three times more than the pulp.
Resonance frequency analysis was first suggested as an alternative method of analyzing peri-implant bone in a scientific paper by Meredith N et al in 1996. [4] As stated in the paper’s abstract, in measuring implant stability and osseointegration, “radiographs are of value, but a standardised technique is necessary to ensure repeatability.” [4] The new technique tested involved ...
The medication will be sold under the brand name Journavx for $15.50 ... "This action and the agency’s designations to expedite the drug’s development and review underscore FDA’s commitment ...
Radiofrequency ablation (RFA), also called fulguration, [1] is a medical procedure in which part of the electrical conduction system of the heart, tumor, sensory nerves or a dysfunctional tissue is ablated using the heat generated from medium frequency alternating current (in the range of 350–500 kHz).
Cytisine, also known as baptitoxine, cytisinicline, or sophorine, is an alkaloid that occurs naturally in several plant genera, such as Laburnum and Cytisus of the family Fabaceae.
Cytidine (symbol C or Cyd) is a nucleoside molecule that is formed when cytosine is attached to a ribose ring (also known as a ribofuranose) via a β-N 1-glycosidic bond. Cytidine is a component of RNA. It is a white water-soluble solid [2] that is only slightly soluble in ethanol. [1]
The delegates to the 1986 conference recommended that the RFA be strengthened by requiring agencies to comply and by providing that agency action or inaction be subject to judicial review. President Ronald Reagan 's 1987 report on small business noted: "Regulations and excessive paperwork place small businesses at a disadvantage in an ...
