Promising Methods of Antibacterial Finishing of Textile Materials.

A review article, containing information on the options, possibilities, and prospects for the development of antibacterial finishing of textile materials, is presented. A wide range of products designed to impart antibacterial, antimicrobial, and antiviral properties to textile materials is considered. The main factors determining the appropriate decision on the technological and functional choice of the protective composition are presented, including the nature of the fiber-forming polymer, the tasks that the resulting material is designed to solve, and its application options.

[The rationale for the application of magnetophoresis for the treatment of intra-articular pathology].

The present study was designed to elucidate the influence of the magnetic field on the spectroscopic characteristics of nimesulide and glucosamine sulfate preparations. The secondary objective of the study was to evaluate the clinical effectiveness of the combined application of magnetotherapy and transdermal forms containing a non-steroidal anti-inflammatory preparation and a chondroprotector with the use of magnetophoresis. For this purpose, we analyzed the samples exposed to the running magnetic field in an infrared spectrometer to elucidate the changes in the optical characteristics of the preparations of interest.

California serogroup viruses from mosquitoes collected in the USSR.

Four California serogroup viruses isolated from mosquitoes in the USSR were tested for antigenic analogy with prototype viruses of the California serogroup. The topotype isolates are biologically similar to, but antigenically different from each other. One is a subtype of snowshoe hare virus, two are different subtypes of Tahyna, Lumbo, and snowshoe hare viruses, and one is identical to Inkoo virus, previously isolated only in Finland.

Identity of Karelian fever and Ockelbo viruses determined by serum dilution-plaque reduction neutralization tests and oligonucleotide mapping.

The causative agents of Ockelbo disease in Sweden, Pogosta disease in Finland, and Karelian fever in the USSR have been attributed to alphaviruses (family Togaviridae) related to Sindbis virus. We compared prototypes Sindbis, Ockelbo, and Karelian fever viruses by neutralization tests. We also analyzed oligonucleotide fingerprint maps of prototypes Ockelbo and Karelian fever viruses and a strain of Sindbis virus from Czechoslovakia.

[Physicochemical properties of the RNA and proteins of an influenza virus H1N3 isolated from an ill child and antigenically analogous to A/whale/TO/19/76].

A comparative analysis of RNA and proteins of influenza A/Baku/799/82, A/whale/TO/19/76, and A/PR8/34 viruses was carried out. The viruses were shown to be similar in their polypeptide composition and oligopeptide maps of the heavy (HA1) and light (HA2) chains of hemagglutinin; in their migration properties of RNA fragments in polyacrylamide gel the A/Baku/799/82 and A/whale/TO/19/76 viruses were similar but not identical. Marked differences in the electrophoretic mobility in gel of RNA fragments coding for P proteins, HA, NP, and NA polypeptides were demonstrated.
