Intracavity enhancement of GFP fluorescence induced by femtosecond laser pulses.

The phenomenon of fluorescence is widely used in molecular biology for studying the interaction of light with biological objects. In this article, we present an experimental investigation of the enhancement of laser-induced fluorescence of Clytia gregaria green fluorescent protein. The laser-induced fluorescence method applied in our work combines the advantages of femtosecond laser pulses and a photonic crystal cavity, with the time dependence of the fluorescence signal studied.

Ghost image restoring using random speckles created by a liquid crystal cell.

A liquid crystal cell is used to produce correlated light beams with speckle structures for implementation of pseudo-thermal ghost imaging. The liquid crystal cell makes it possible to provide random spatial intensity distributions, which are characterized by a low coefficient of mutual cross correlations. Ghost imaging of an object representing an amplitude mask is demonstrated.

[The functional classification of velopharyngeal closure after uranoplasty].

The new nasopharyngoscopic functional classification of palatopharyngeal joining is based on the results of examinations of 57 children with congenital uranoschisis after uranoplasty and 19 healthy children aged 5 to 14 years by nasopharyngoendoscopy. The classification defines the causes of palatopharyngeal insufficiency and for the first time takes into consideration the disagreement between the palatopharyngeal lock and articulation. The proposed classification helps select the most effective method of rehabilitation of the above patient population and helps follow up the time course of changes in the function of the palatopharyngeal lock under the effect of treatment.

[Programmed multichannel bioelectrical management in the treatment of children with secondary osteoarthrosis deformans of the temporomandibular joint under computed tomographic control].

Programmed multichannel bioelectrical regulation was used in the treatment of 19 children aged 5 to 14 with osteoarthrosis deformans of the temporomandibular joint. The treatment resulted in amelioration of the joint function in all the patients: opening of the mouth increased by an average of 7.5 mm, the volume and density of the lateral and medial pterygoid muscles increased, and the density of osseous tissue of the joint process decreased.
