A practical deuterium-free NMR method for the rapid determination of 1-octanol/water partition coefficients of pharmaceutical agents.

A simple and rapid NMR method is described to determine the logP of pharmaceutical agents. This method is highly versatile and efficient, because it does not require the use of deuterated solvents or the addition of any internal/external standards to the sample. We demonstrate that logP can be accurately measured using NMR for pharmaceutical agents with known logP values.

The Mayo Clinic experience with the cochlear implant.

The implantation of a cochlear electronic prosthetic device is an acceptable means of improving the communication ability of pre- and postlingually deafened children and adults. A significant number of patients in this series are in the senior citizen age group. It has been beneficial in improving communication ability in selected profoundly deafened individuals.

Pluronic F-127 gel preparation as an artificial skin in the treatment of third-degree burns in pigs.

A blinded study was designed to provide qualitative and quantitative evaluation on the possible therapeutic benefits of the use of Pluronic Polyol F-127 as a substitute skin in standardized third-degree thermal burns. Three separate burns, approximately 1600 mm2, were induced on the shaved backs of young, anesthetized pigs. Each animal served as its own control.
