Antidepressants are the first-line treatment of major depressive disorder, but response rates following the first antidepressant medication are moderate.Clinical efficacy requires to overcome the blood-brain barrier where p-gp molecules are located. If they recognize and bind an antidepressant, they pump it back into the circulation. If the antidepressant is not recognized, the passage is not impaired...
Monitoring the water status of economic plants is of vital importance for optimizing irrigation strategies and for a deeper understanding of the influence of drought stress. Most of the conventional techniques for measuring the water content of plants are destructive. Here, we use terahertz (THz) waves to non-destructively determine the water status of living plants. Terahertz waves are somewhat less...
We present an electromagnetic model of plant leaves which describes their permittivity at terahertz frequencies. The complex permittivity is investigated as a function of the water content of the leaf. Our measurements on coffee leaves (Coffea arabica L.) demonstrate that the dielectric material parameters can be employed to determine the leaf water status and, therefore, to monitor drought stress...
An electromagnetic model of plant leaves at THz frequencies is presented. It allows for the determination of the leaf water status. The model bases on an effective medium theory and extends the model by Landau, Lifshitz, and Looyenga. The influence of scattering, which is dominant at higher frequencies, is described by a Rayleigh roughness factor. Results of THz time-domain spectroscopy measurements...
