Productivity of Concentration-Dependent Conversion of Substitutional Nitrogen Atoms into Nitrogen-Vacancy Quantum Emitters in Synthetic-Diamond by Ultrashort Laser Pulses.

Tightly focused 515-nm, 0.3-ps laser pulses modify in a laser filamentation regime the crystalline structure of an Ib-type high-pressure, high-temperature (HPHT) synthesized diamond in a thin-plate form. The modified microregions (micromarks) in the yellow and colorless crystal zones, possessing different concentrations of elementary substitutional nitrogen (N) impurity atoms (C-centers), exhibit their strongly diminished local IR absorption (upon correction to the thickness scaling factor).

[Sulfonium derivatives of thioxanthenone, a new class of photodetritylating agents for microarray oligonucleotide synthesis].

The usability of a new class of photo acids, namely, sulfonium hexaphosphates based on thioxanthenone, for the removal of the dimethoxytrityl protective group in the process of oligonucleotide synthesis has been studied in order to search for new detritylating agents for microarray oligodeoxyribonucleotide synthesis. 2,4-Diethyl-9-oxo-10-(4-heptyloxyphenyl)-9H-thioxanthenium hexafluorophosphate has been successfully used for the solid-phase synthesis of (dT)(10).

[Rapid identification of mycobacteria using laser fluorescence].

Aim: To develop rapid method of identification of mycobacteria based on laser fluorescence.

Materials And Methods: Characteristics of laser-induced fluorescence of 19 bacteria species, including 17 species of mycobacteria, were studied. Identification of microorganisms was performed using measurement of spectral-fluorescent characteristics.

[Antimicrobial activity determination of the preparations used in comprehensive treatment of patients with parodontitis].

Determination of antimicrobic activity of the preparations of Metrogyl denta, Cholisal and Solcoseryl on the complex culture of microorganisms employing the developed procedure was carried out. Degree of the antimicrobic action manifestation of each preparation was revealed.

[Modelling of photoinducted diffusion of antimicrobial preparations in gingival tissues and face skin].

The study was made of laser radiation influence upon diffusion speed of medicines applied on tissue surface. Photophoresis use allow to increase diffusion speed of medicines applied on parodontal tissues and face skin during photophoresis process.
