[A Case of Apical Hypertrophic Cardiomyopathy With Rare Anomaly of Coronary Arteries Origin].

A clinical case of apical hypertrophic cardiomyopathy (HCM) in 44­years old man is presented. In this patient exercise ECG testing and 24­hour ECG monitoring revealed exercise-induced ST depression in the angiographically confirmed absence of coronary atherosclerosis. The uncommonness of this observation was the combination of HCM with a rare anomaly of coronary arteries origin.

[Conjugates of cyclooligosaccharide scaffolds and carbohydrate ligands: methods of synthesis and interaction with lectins].

Main approaches to the preparation of mono- and oligodentate glycoconjugates based on cyclodextrin and cyclooligo-ß-(1 -> 6)-D-glucosamine scaffolds are surveyed in the review. The data on the biological activity of the glycoconjugates by the example of their interaction with lectins are discussed.

Morphology and dynamics of the upper cloud layer of Venus.

Venus is completely covered by a thick cloud layer, of which the upper part is composed of sulphuric acid and some unknown aerosols. The cloud tops are in fast retrograde rotation (super-rotation), but the factors responsible for this super-rotation are unknown. Here we report observations of Venus with the Venus Monitoring Camera on board the Venus Express spacecraft. We investigate both global and small-scale properties of the clouds, their temporal and latitudinal variations, and derive wind velocities. The southern polar region is highly variable and can change dramatically on timescales as short as one day, perhaps arising from the injection of SO2 into the mesosphere. The convective cells in the vicinity of the subsolar point are much smaller than previously inferred, which we interpret as indicating that they are confined to the upper cloud layer, contrary to previous conclusions, but consistent with more recent study.
