[Possibilities of magnetic resonance morphometry and laboratory biomarkers in studying the progression of multiple sclerosis].

Objective: To show that magnetic resonance morphometry and laboratory biomarkers are promising methods for early detection of progressive forms of multiple sclerosis (MS).

Material And Methods: Eighty-one patients with MS were examined, magnetic resonance morphometry was performed in all of them, 60 patients were analyzed for neurofilament light chains (sNFL), phosphorylated neurofilament heavy chains (spNFH) and glial fibrillary protein (sGFAP) in serum by enzyme-linked immunosorbent assay.

Results: Brain volumes were negatively correlated with disease duration, EDSS score, 25-foot walk test score and 9-ring test and positively correlated with the Symbol-Numeric Test and the Montreal Cognitive Assessment.

[Objective assessment of donor material for penetrating corneal transplantation].

Unlabelled: Reliable suitability evaluation of donor material is the crucial issue of penetrating corneal transplantation. The main parameter to be considered is endothelial cell density (ECD). However, when it comes to practice, one has to admit significant variation in ECD readings of cadaver corneas obtained by different methods.

[The epidemiology of Yersinia infections in the central taiga subzone of the eastern European plain].

The seroepidemiological survey of the population in four southern regions of the Komi Republic for the presence of pseudotuberculosis and enteric yersiniosis was carried out. The survey revealed a high level of seroconversions to with respect to enteric yersiniosis (26.2 +/- 2.

[The prevalence of cryptosporidiosis among the city population of Russia and Belarus].

A total of 248 adults (170 with somatic diseases and 78 with the diarrheal syndrome) and 1206 children (323 attending kindergartens, 231 with somatic diseases, and 652 with the diarrheal syndrome), residents of seven towns of Russia and Belarus, were examined for cryptosporidiosis in 1989-1992. The mean infection rate of children and adults with the diarrheal syndrome was 4.8 and 2.
