Hemocompatibility of Galactomannan and Galactoglucomannan Sulfates in In Vitro Experiments.

We identified compounds that do not independently provoke aggregation of human platelets and do not affect hemolysis of human erythrocytes in vitro: lacking anticoagulant activity sulfated galactoglucomannan (polydispersity 1.43; degree of sulfation 0.66) in concentrations ≤0.

[The genetic aspects of occupational hearing impairment].

This article was designed to be the overview of the current literature publications concerning the identification of the genetic markers of susceptibility to the noise-induced loss of hearing. The analysis of these data has demonstrated that the major gene polymorphisms associated with the development of this pathological condition are localized in the genes encoding for the antioxidant systems, potassium homeostasis, and adhesion molecules as well as in the genes involved in intercellular coupling, the mechanisms underlying the cellular response to stress, activation and regulation of heat shock proteins, and signaling function of the immune system. It is concluded that the further investigations into the genetic aspects of the full-genome sequencing techniques and the search for genomic associations could greatly contribute to the development of personalized medicine and the reduction of risks of occupational noise-induced sensorineural impairment of hearing.

[Characteristic of the microbiocenosis of the nasal mucous membrane in the patients presenting with acute bacterial rhinosinusitis].

The objective of the present work was to study the specific features of the microbiocenosis of the nasal mucous membrane in the patients presenting with acute bacterial rhinosinusitis (ABRS). We examined 86 patients with this condition at the age varying from 18 to 64 years. The control group consisted of practically healthy blood donors (n=156) registered at the Krasnoyarsk Regional Blood Centre #1; they were matched to the patients of the main study group in terms of the age and sex.
