Evolution in pecunia.

The paper models evolution in pecunia-in the realm of finance. Financial markets are explored as evolving biological systems. Diverse investment strategies compete for the market capital invested in long-lived dividend-paying assets.

[Inflammatory nature of colon diverticula].

On the basis of morphological and immunological study of biopsies of the colon in patients with diverticulosis was revealed that microscopic inflammation of the mouth of the diverticulum is characterized by several features that include excessive proliferation of the epithelium, the predominance of macrophage reaction in the development of the immune response, increased cell adhesion and unusual ratio between the expression of cytokines and other regulatory molecules. Changes in the structure of the formed diverticula tissue are associated with dysregulation of many processes of tissue metabolism and morphogenesis. These include the dysregulation of cell renewal of the epithelium (increased level of proliferation of epithelial cells and inhibition of apoptosis), degradation of extracellular matrix components, moderate vascular reaction.

[Clinical and morphological variants of diverticular disease in colon].

Our own results of two-stage research are presented in the article. The first stage contains the retrospective analysis of 3682 X-ray examining of large bowel which were conducted in 2002-2004 to define the structure of colon disease and to determine gender differences. The second stage is prospective research which took place from 2003 to 2012 and 486 patients with diverticular disease were regularly observed.

Regeneration of colorectal epithelium in diverticulosis.

Excessive poorly differentiated epitheliocytes were detected in the crypts and subepithelial regions of the colorectal mucosa during the regeneration process in the majority of patients with diverticular disease. The compensatory reaction of the sigmoid mucosa decreased, which was seen from rarely detected cryptic hyperplasia. Disorders in the epitheliocyte proliferation and differentiation were paralleled by changes in tissue levels of proinflammatory cytokines (elevation of TNF-α and IFN-γ and reduction of IL-1β and IL-8) and increase of IL-4, regulating lymphocyte activation.

[Child psychoanalysis and child psychiatry in Russia, from Lenin to the present day].

Russian child psychiatry and psychoanalysis painfully recover after being brought under the subjection of "paedology", a synthetic so-called science, and enslaved to the utopian Soviet expectation of building a "new man" in 1920-1930. Later on, in 1940-1980, under the precarious shelter of Soviet social work, they could indulge in the psychodynamic viewpoint. Liberated in 1985-1991, Russian child psychiatry and psychoanalysis take up again with Western science to answer the urgent demand for care for the psychic sufferings of young Russians.
