Laudanum by pharmacists in preparing Paregoric from Laudanum, and to note that the dosages in this article refer to Apothecaries weight and fluid measure. In particular, "the difference between a minim and a drop should be borne in mind when figuring doses. A minim is always a sixtieth part of a fluidrachm regardless of the character of the substance, while a drop varies from a forty-fifth to a two-hundred-and-fiftieth part, according to the surface tension of the fluid." Tincture of Opium (Laudanum) and Camphorated Tincture of Opium (Paregoric) each have 50.9 drops per gram; 50.0 drops per cc; 185.0 drops per
Precision medicine As the exposome is a common concept of epidemiology, precision medicine is intertwined with molecular pathological epidemiology, which is capable of identifying potential biomarkers for precision medicine. The ability to provide precision medicine to patients in routine clinical settings depends on the availability of molecular profiling tests, e.g. individual germline DNA sequencing. While precision medicine currently individualizes treatment mainly on the basis of genomic tests (e.g. Oncotype DX), several promising technology modalities are being developed, from techniques combining spectrometry and computational power to real-time imaging of drug effects in the body. Many different aspects of precision medicine are tested in
