The long-term outcomes of treatment with new selective antipsychotic for patients with schizophrenia have been discussed. Using the example of patients treated with “Xeplion” for secondary prevention of worsening symptoms of the disorder and changing in patient social functionality are in the focus....

The model for assessing radio communication aids reliability in the form of discrete semi-Markovian process which characteristics are determined by the characteristics of acting interferences is offered and justified in the article. The method of calculating the reliability indexes of the radio comm...

The dynamics of class B lasers with the incoherent optical feedback formed by quickly vibrating external mirrors is viewed. The problem of the stability of equilibrium in a model system with rapidly oscillating coefficients is studied. The averaged system with the distributed delay is received. It i...

We studied gender-specific clinical manifestations and risk factors for gastroesophageal reflux disease (GERD) in the urban population of Ulan-Ude. The study included 352 patients with GERD. It was found that in both sexes prevailed not erosive reflux disease. It was detected in 64,2% of men and in...

The problem about the local dynamics of the logistic equation with rapidly oscillating time-periodic piecewise constant coefficient of delay was considered. It was shown that the averaged equation is a logistic equation with two delays. The criterion of equilibrium point stability was obtained. Dyna...

Malignant transformation of any cell is associated with numerous physiological and morphological disorders at both genomic and protein levels, a variety of macromolecules being involved in. However, the tumour development and metastasis depends on not only the molecular characteristics of the tumour...

We study a model of single-mode semiconductor laser with the optical feedback. This model bases on DDE (Lang–Kobayashi model). With the help of local analysis methods we built a continuous set of quasinormal forms in the neighbourhood of critical values. The ability of coexistence of a large number...

A dynamical model of laser generation based on monomode balance equations with delay is studied. Methods of a local analysis are used to build sets of quasinormal forms in the neighborhood of parame^ters bifurcation values. The possibility of the coexistence of a large number of steady oscillating s...

Abstract. We have shown that polyprenyl phosphate (phosprenyl) competes with interleukin 2 for binding with serum γ-globulin. It was also demonstrated that phosprenyl restores delayed type hypersensitivity induced by Listeria monocytogenes, after its inhibition with a γ-globulin which binds to IL-2...

INTRODUCTION. Currently in the Russian Federation and the Eurasian Economic Union (EAEU), the conduct of non-clinical studies of radiopharmaceuticals is regulated by general guidelines on non-clinical studies, which are applicable to multiple groups of medicinal products but do not accommodate the c...

Abstract. A full-scale development of post-vaccinal immunity is determined by T and B cell-dependent immunological memory which is formed in response to vaccine injection. However, a capacity of existing and newly developed vaccines to stimulate T cell-dependent immunological memory is very poorly s...

Abstract. Local immune responses of mucous membranes of an organism are the first and most significant barriers preventing many virus infections, including influenza. The barrier against influenza infection is the mucosalassociated lymphoid tissue of the upper airways. It is considered, that nasopha...
