[Combined use of the unit AMUS-01-INTRAMAG and AIR-U-plus device in the treatment of chronic bacterial prostatitis].

The studies of the authors including 60 patients with chronic bacterial prostatitis and erectile dysfunction allowed them to conclude that a combination of systemic and local antibacterial treatment, physiotherapy with introduction of proteolytic enzymes in the prostatic gland has advantages over combined chemotherapy.

Forward scattering of light in thin opal films.

Angle-resolved spectra of the light scattered in a thin opal film have been measured behind the sample in three configurations, which differ by directions of the light incidence and detection. Two minima have been observed in scattering spectra and assigned to the attenuation by the (111) Bragg photonic bandgap along directions of the incident and detected photon flux. The irrelevance of the photonic bandgap minima to the actual path of scattered photon has been demonstrated. The projection of the directional (111) photonic band gap has been allotted to the plateau observed in the angle diagrams of the scattered light intensity. The spectra and the angle diagrams of the scattered light have been interpreted in terms of the weak scattering regime, when scattering serves for coupling a photon from one eigenmode of opal to another.

Emission stimulation in a directional band gap of a CdTe-loaded opal photonic crystal.

An anisotropic photonic crystal light source has been realized by impregnation of a thin film latex opal with brightly luminescent CdTe nanocrystals. Its photoluminescence along a given direction has been studied as a function of excitation power. An increase of the photoluminescence saturation threshold in the directional photonic band gap has been observed. This result is interpreted as a stimulation of emission coupled to specific eigenmodes of a directional band gap. A theoretical model exploiting the low group velocity eigenmodes has been elaborated to explain the resonance character of the emission with band gap frequencies.

Diffraction of light from thin-film polymethylmethacrylate opaline photonic crystals.

Photonic crystals in the form of large area thin films consisting of closely packed polymethylmethacrylate beads were sedimented on glass substrates. The high ordering of the opaline films made it possible to observe a number of fine features in the optical diffraction, including Fabry-Perot oscillations of the reflectivity and branching of the angular dispersion of the Bragg resonances with increase of the angle of incidence of the light beam. Results of calculations of the photonic band structure and simulations of the reflectance spectra agree well with experimental observations.
