In the present research, we have studied an influence of enhanced expression TRIM14 on alphavirus Sindbis (SINV, Togaviridae family) infection. In the HEK293 cells transfected with human trim14 gene (HEK-trim14), SINV yield after infection was decreased 1000-10,000 times (3-4 lg of TCD50/ml) at 24 h p.i. and considerably less (1-2 lg of TCD50/ml) at 48 h(More)
The case of a biological population, which consists of several sub-populations (different kinds of the population ”social” groups: families, bevies, etc.), has been considered. For description of non-trivial interactions between these groups, a model of ”open the Eigen hypercycle” has been proposed. Its bifurcation analysis for 3-dimension case has been(More)
The contribution is devoted to qualitative investigation of subpopulation dynamics, described by a degenerate differential model with basic logistic function. The research includes: finding stationary sets, such as isolated special points and stationary hyper-planes, investigation of their stability, complete classification of system phase portraits,(More)
Models of the long-term ecological successions are considered. The model of open Eigen’s hypercycle has been used to model the process. It is shown that ecological succession is a complex process with ability for self-organisation. It is distinguished two type of selforganisation: by adjusting system control parameters or by change of quantity of its(More)
A development quadratic model of the heterogeneous biological population consisting of a few sub-populations is investigated. The classic stabilization problem of solutions for the system of ordinary quadratic differential equations, which describing this model, is solved. Examples are given. 2013 Elsevier Inc.
