Rhinoviruses (RV) are the etiological factors of not only acute respiratory diseases of the common cold type but also of acute and chronic diseases of otorhinolaryngological organs. Virological and bacteriological examinations of patients with chronic pneumonia in the stages of exacerbation and incomplete remission revealed a high degree of the infection(More)
To study the effect of antisense E1a RNA (asRNA) on adenovirus development, two types of adenovirus 5 E1a antisense constructs have been engineered. One was complementary to the viral DNA region [nucleotide (nt) positions 500-720] regulated by the metallothionein-I promoter, and the other was complementary to the DNA regions (nt positions 630-1570) under(More)
Virological, serological and immunofluorescence studies revealed circulation of rhinoviruses of the strains 1A, 1B, 2, 3, 7, 9, 10, 12, 13, 14, 16-23, 27, 29-33, 42, 48, 53, 56, 60 and 69 on the territory of Czechoslovakia and the Soviet Union. According to virological results, type 48 predominated and was followed in frequency of occurrence by types 27, 14(More)
Transformed rat cells and hamster tumoral cells, obtained after treatment with DNA of monkey adenovirus SA7 which was fragmented using endonuclease SalI, contained all the SalI fragments of SA7 DNA integrated with the cell genomes. As shown by blotting hybridization distinct deletion did not form in the fragments of viral DNA on integration. Insertion of(More)
A diagnostic preparation was obtained by sensitization of formalinized sheep erythrocytes with antibody to rhinovirus type 17. This preparation was agglutinated in the presence of relatively high concentrations of type 17 but not other types of rhinovirus. It could also be used for detection of antibody to rhinovirus type 17 in the antigen neutralization(More)
Northern wetlands ecosystems play an important role in the hydrological balance of neighboring areas, where they act as chemical barriers against anthropogenic and technogenic contaminations. Studied region is well known for quantity of peat deposits and the volume of peat resources. Peat can be considered as a highly informative marker for assessing change(More)
The modification of disc electrophoresis technique in polyacrylamide gel with sodium dodecylsulphate (SDS) has been elaborated for synchronous isolation of some structural proteins in biologically active form and in preparative quantities from adenoviruses. Virions of SA7 adenovirus were mildly dissociated in SDS solution at 20 degrees C and structural(More)
