Impact of different strains on secondary metabolites accumulation in L. hairy roots and antiviral activity of their extracts against influenza virus of subtypes A (H5N1) and A (H3N2).

To optimize protocol for obtaining hairy roots of L. with high antiviral activities, factors such as four strain types of (A4, ATCC15834, R-1601, 8196), two explant types, namely cotyledonous and primary leaves of seedlings, and different cultivation durations (30 and 90 d) were studied. The formation of hairy roots was observed after 2 to 4 wk of incubation, depending on the type of explant and the strain of used.

L. hairy root culture as a source of compounds with antiviral activity against influenza virus subtypes А(H5N1) and А(H3N2).

The hairy root culture of halophyte was obtained by transforming seedlings' primary leaves with a wild strain of 15834 SWISS (transformation frequency was 78.7%). The roots' transgenic status was confirmed by PCR analysis using -, -, -, -specific primers.

[Association of 2B-adrenergic receptor gene polymorphism with disturbances of cardiac conduction].

In this work we for the first time revealed on clinical - genetic material association between hereditary disturbances of cardiac conduction and polymorphism of 2-adrenergic receptor gene.

[Polymorphisms of 2B-adrenergic receptor and endothelial NO-Synthase genes in genesis of the hereditary sick sinus node syndrome].

In this work we have demonstrated for the first time on the clinico-genetic material association between hereditary sick sinus node syndrome (SSNS) ADRA2B and eNOS genes polymorphisms. We have established predominance of homozygote genotype of more rare DD allele in patients with SSNS (28%) compared with subjects of control group (8.99%).

[Polymorphism of connexin 40 gene-- a novel genetic marker of the sick sinus node syndrome].

In this work we have demonstrated for the first time on the clinico-genetic material association between hereditary sick sinus node syndrome and connexin 40 gene polymorphism. We have revealed that heterozygous variant of connexin 40 gene variant is more frequent among patients with sick sinus node syndrome and their healthy relatives than in persons of control group.
