Adaptive finite element eye model for the compensation of biometric influences on acoustic tonometry.

Background And Objective: Glaucoma is currently a major cause for irreversible blindness worldwide. A risk factor and the only therapeutic control parameter is the intraocular pressure (IOP). The IOP is determined with tonometers, whose measurements are inevitably influenced by the geometry of the eye.

A new method for the preparative isolation of chlorogenic acid lactones from coffee and model roasts of 5-caffeoylquinic acid.

Chlorogenic acid lactones (CQL) are known to contribute to the bitter taste of roasted coffee. CQL might also have beneficial biological activities. Until now, there is a lack of pure standard compounds for quantification and biological testing.
