[Detection of the nuclear polyhedrosis virus DNA in samples from eggs and caterpillars at different stages of the gypsy moth Lymantria dispar (L.) population dynamics].

The nuclear polyhedrosis virus (NPV) DNA was detected in samples from eggs and caterpillars of the gypsy moth collected in natural populations of the Western Siberia and Ural by means of PCR with primers corresponding to the polyhedrin gene. According to censuring data, the gypsy moth populations of Western Siberia were at the depression stage. The NPV DNA detection frequencies in eggs (8.

[Clinico-pathogenetic significance of enzymes regulating nucleic metabolism in erythrocyte lysates and sera of patients with osteoarthrosis].

Lysates of erythrocytes and sera of 52 patients with osteoarthrosis (OA) and 30 healthy subjects were used used to determine adenosine deaminidase (ADA, AMP deaminase (AMPDA) and adenine deaminidase (AD). Their activities were unrelated to the age and sex of the patients. At admission, patients with OA showed enhanced activity of ADA in sera and reduced activity of AMPDA and AD in lysates compared with normal values.

[The clinical diagnostic value of a study of the activity of enzymes of the guanyl branch of purine metabolism in patients with ankylosing spondyloarthritis].

Aim: To assess the diagnosis of the activity of a pathological process in patients with ankylosing spondyloarthritis (AS) and to reveal purine metabolic (PM) changes in relation to the clinical features of AS.

Materials And Methods: The serum activities of the PM enzymes: xanthine oxidase (XO), guanine deaminase (GDA), guanosine deaminase (GSDA), purine nucleoside phosphorylase (PNP), guanosine phosphorylase (GP), and adenosine deaminase (ADA) were determined in 55 patients (51 males and 4 females) aged 36.0 +/- 1.

[Phenotypic and genetic characterization of nuclear polyhedrosis virus isolated from gypsy moth (Lymantria dispar L.) larvae from the natural populations of Western Siberia].

Six nuclear polyhedrosis virus (NPV) isolates have been isolated from dead larvae of gypsy moth in Western Siberia. Heterogeneity of virulence and reproduction activity was revealed for the NPV isolated by bioassay with Lymantria dispar L. larvae.

[The dynamics of phenolic compounds and soluble sugars in the leaves of the silver birch (Betula pendula Roth) after defoliation and their significance in entomological plant resistance].

The dynamics of phenolic compounds, flavonols, catechines, tannins, and soluble sugars in the leaves of the silver birch Betula pendula Roth after strong (75%) and total (100%) artificial defoliation was studied. It was shown that the flavonol content in the leaves did not change after strong and total defoliation, while the amount of tannins did not change during the first 15 days but increased later on 1 and 2 years after 75% and 100% defoliation. The catechine content did not change during the first 15 days and increased later on 1 year after strong and total defoliation; however, it returned to the level of control plants 2 years after both types of defoliations.
