Comparison of the presence of chemical and biomarkers in the surface microlayer in water areas of health resort zones of Lake Baikal and in atmospheric aerosol of this region

The search for the chemical and biomarkers of aerosol originating from the surface microlayer (SML) of water areas of health resort zones at Lake Baikal was performed. The concentrations of Ca, Mg, Na, K, Cu, Zn, Fe, Mn, Al, Ba, Pb, Cd, As, naphthalene, acenaphthene, acenaphthilene, fluorene, phenanthrene, anthracene, fluoranthene, pyrene, benz(a)anthracene, perilene, benz (b) fluoranthene, benz(a) pyrene,1,2,5,6-dibenz anthracene, benz(ghi) perilene, and total protein in aerosols and water samples collected from the region were experimentally studied. A direct close interrelation was revealed between the concentrations of all chemical elements in aerosol and water samples. The highest concentrations were recorded for Ca, Mg, Na, and K. A polymerase chain reaction method was employed to determine the similar interrelation between the genetic materials of microorganisms (bacterioplankton) found in water and aerosol. A completely adequate marker reflecting the presence of aerosol generated by SML of Lake Baikal water was not found.

The Possibility of Hemorheological Parameters as Precursors of Recurrent Strokes

The study aimed to evaluate the possibility of application of hemorheological parameters as precursors of recurrent strokes in cases of various pathogenetic forms of the disease.

Optical methods in diagnostics of liver fibrosis via blood observation

A possible application of optical methods (dielectrophoresis, spectral and imaging ellipsometry, Fourier- transform infrared spectroscopy, Raman spectroscopy) for the early diagnostics in studies of red blood cells and serum in patients with the diffuse liver disease, with varying degrees of fibrosis, has been evaluated. As experimentally confirmed, the combined optical methods significantly improve the sensitivity, specificity and accuracy index in the diagnosis of both severe fibrosis and slight ulterior liver fibrosis. The identified optical methods diagnostic potential can be efficiently utilized in noninvasive screening evaluation of the stages of diffuse liver disease of various genesis.

Dielectrophoresis applications and electric rotations in medicine: Metrology objectives

A brief literature review of the foundations of the theory of dielectrophoresis and electrorotation of a cell in an electric field, and the extent of their practical application in the field of medicine, microbiology, virology, biophysics are provided. Primary concerns of metrological provision of traceability of measurements in the field of dielectrophoresis and rotation of the cell as per Federal Law No. 102-FZ are grounded.
