A comprehensive account on the role of efflux transporters in the gastrointestinal absorption of 13 commonly used substrate drugs in humans.
TLDR
The present findings, however, do not de-emphasize potential in vivo importance of efflux transporters in affecting (increasing or decreasing) oral absorption of certain substrate drugs, especially those with low to moderate intestinal permeability and with low therapeutic index.
Use of the erythromycin breath test for in vivo assessments of cytochrome P4503A activity and dosage individualization
TLDR
It is necessary to select patients suitable for vaginal or laparoscopic mesh placement for use in the neonatal intensive care unit based on prior history and once they provide informed consent for surgery.
Similarity in the linear and non-linear oral absorption of drugs between human and rat.
TLDR
For Fab not limited by the solubility problem, the great similarity in Fab between human and rat in linear absorption range can be rationalized by the similar t and k, which may be valuable in drug development.
[Studies on analytical method for 10 drugs of abuse in urine using HPLC].
TLDR
Precision and linearity of the method are satisfactory for clinical toxicological applications and the extraction procedure yielded cleaner extracts, and the recovery rates from urine were all above 87% without interference.
[Study on lignans from Diphylleia sinensis].
A new lignan along with eight known lignans and a flavonoid were isolated from the rhizomes of Diphylleia sinensis Li.. Their structures were elucidated on the basis of chemical and spectral

TLDR
A simple, sensitive and accurate method has been applied to the analysis of various samples and can be used for the quality control of Diphylleia sinensis, podophyllum and dysosma preparations used in clinic.

TLDR
The visible absorption spectra of a red colour, produced by adding one drop of the solution of sodium hypochlorite to a solution of berberine hydrochloride in 8 N hydrochloric acid, were studied and the colour intensity was found to obey Beer's law.
