The limiting case of the system of equations of two-dimensional gas dynamics in the presence of the Coriolis force, which can be obtained under the assumption of small pressure, is considered. With this approach, the equation for the velocity vector (transport equation) is decoupled from the system and can be solved separately. An explicit asymptotic representation of a smooth solution to transport equations is obtained with the use of the method of stochastic perturbation along characteristics and the process of formation of solution singularity is analyzed on a specific example. It is concluded that the presence of the Coriolis force prevents formation of singularities.

A comparison of ivabradine and omega-3 polyunsaturated fatty acids, drugs with principally different mechanisms of action, is presented in patients with chronic heart failure (CHF) on the base of GISSI-HF and SHIFT trails results. It is essential to compaire an effect of these drugs on the morbidity and mortality in combined therapy of patients with CHF , because each additional drug may change in compliance to treatment, induces additional costs or may be a reason of new side effects. Additional (to standard therapy) effects of ivabradine and omega-3 polyunsaturated fatty acids are discussed.

The review gives data on the epidemiology, terminology, diagnostic criteria, and standards for the examination and treatment of patients with vascular cognitive disorders and vascular dementia (VD). The heterogeneity of vascular cognitive disorders, concurrence of vascular and neurodegenerative diseases are discussed. Data from studies of specific therapy for VD are given.
