Fundamental solutions and dual boundary element methods for fracture in plane Cosserat elasticity.

In this paper, both singular and hypersingular fundamental solutions of plane Cosserat elasticity are derived and given in a ready-to-use form. The hypersingular fundamental solutions allow to formulate the analogue of Somigliana stress identity, which can be used to obtain the stress and couple-stress fields inside the domain from the boundary values of the displacements, microrotation and stress and couple-stress tractions. Using these newly derived fundamental solutions, the boundary integral equations of both types are formulated and solved by the boundary element method.

[Special features of pathogenesis and pharmacotherapy of chronic heart failure in women].

At present in Europe number of deaths due to diseases of cardiovascular system in women has exceeded number of deaths in men. It has been established that process of cardiac remodeling proceeds differently in women and men. This determines different prognosis of the course of chronic heart failure.

[The effect of pyridinolcarbamate (parmidine) on the microcirculation and immunity of patients with stable angina].

A comparison of the efficacy of treating two patient group (Group 1, patients receiving nitrates in combination with parmidin and Group 2, those taking nitrates) revealed that the two groups did not differ greatly in the clinical effects. In heart failure patients with high capillary permeability, parmidin substantially decreased the permeability to protein, which was associated with decreases in the baseline high activity of primary lipid peroxidation product in plasma red blood cells, which was not observed in the controls. At the same time parmidin was demonstrated to exert an unfavourable effect on microhemocirculation and to increase the patient's autosensibilisation.

[Effect of hemosorption on microcirculation, humoral autoimmunity and lipid peroxidation in patients with stable angina pectoris].

Microhemo- and lymphocirculation, capillary permeability, humoral autoimmunity and lipid peroxidation were determined in 46 patients with Functional Classes III-IV stable angina concurrent with multiple atherosclerotic coronary lesions 24 hours following the second hemosorption session. The clinical efficiency of hemosorption was observed in 47.8% of patients with stenotic coronary atherosclerosis refractory to antianginal therapy.
