A model of weak viability selection at two multi-allele loci with standardization of approaches through the use of perturbation theory is examined. The estimate of the quasi-equilibrium value for the linkage disequilibrium coefficient D is analyzed, and results in terms of average effects in quantitative genetics and in terms of the theory of singular perturbations in mathematics are obtained. The approximation of a discrete-time model of a random mating population with non-overlapping generatio...

In vitro, endothelium-dependent relaxation mechanisms of smooth muscle cells of the bovine mesenteric lymph node capsule have been studied. The addition of L-NAME and indomethacin to physiological saline inhibited the production of endothelium NO and prostacyclin. In this solution, tetraethylammonium chloride and TRAM-34 increased the tone of the precontracted lymph nodes. Thus, in bovine mesenteric lymph nodes there is an relaxation mechanism mediated by endothelial hyperpolarization, realized ...
Anodization of titanium implants is accompanied by the formation of titanium oxide nanotubes improving osseointegration. An excessive fibroblast adhesion on the surface might lead to the formation of fibrous capsule resulting in implant rejection. In our research, we demonstrated that the adhesion activity of human dermal fibroblasts on anodized surface was not elevated, which is promising for the use of titanium with nanotube-layered surface for implantology.
