BACKGROUND The alpha-helical coiled coil structures formed by 25-50 residues long peptides are recognized as one of Nature's favorite ways of creating an oligomerization motif. Known de novo designed and natural coiled coils use the lateral dimension for oligomerization but not the axial one. Previous attempts to design alpha-helical peptides with a… (More)
Epigenetic mechanisms of gene regulation in context of cardiovascular diseases are of considerable interest. So far, our current knowledge of the DNA methylation profiles for atherosclerosis affected and healthy human vascular tissues is still limited. Using the Illumina Infinium Human Methylation27 BeadChip, we performed a genome-wide analysis of DNA… (More)
Efficient syntheses of O-acyl Tyr-peptides allow chemical long-range ligation (O-acyl to N-acyl transfer) via each of 12- to 19-membered cyclic transition states. The results represent the first examples of successful isopeptide ligations starting from O-acyl Tyr-peptides.
There have been obtained high-filling polyurethane compositions with hydroxyapatite. Compositions with hydroxyapatite and immunomodulator in the polyurethane base acquire better adhesiveness and improved strength characteristics as evidenced by physical-and-clinical studies made. Modal operations are developed in test animals on bone defects replacing that… (More)
We investigate variations in the location and intensity of the auroral electrojets during magnetic storms and substorms using a numerical method for estimating the equivalent ionospheric currents based on data from meridian chains of magnetic observatories. Special attention was paid to the complex structure of the electrojets and their interrelationship… (More)
The clinico-epidemiological analysis of morbidity in Crimean haemorrhagic fever in the Stavropol Territory is presented. Information on the clinical features, epidemiological characteristics and diagnostic criteria of the disease, as well as trends in its treatment, is given.
A comparative analysis of results of 70 operations fulfilled by the method of classical with autovein plasty of the internal carotid artery (ICA) and of 103 operations by the method of eversion carotid endarterectomy (CEAE) was made. The time of compression of the carotid artery during the eversion CEAE proved to be considerably less (22.5 +/- 6.5) min,… (More)
