Very low (nano- and subnanomolar) concentrations of 10-(6'-plastoquinonyl) decyltriphenylphosphonium (SkQ1) were found to prolong lifespan of a fungus (Podospora anserina), a crustacean (Ceriodaphnia affinis), an insect (Drosophila melanogaster), and a mammal (mouse). In the latter case, median lifespan is doubled if animals live in a non-sterile vivarium.… (More)

The pigment epithelium cell structure and therapeutic effect of antioxidant SkQ1, selectively penetrating into mitochondria from eye drops, were studied upon development in OXYS rats of age-related retinopathy as a model of macular degeneration. The characteristic dynamics and ultrastructural peculiarities of the layer of electron-dense cytoplasmic… (More)

We present a continuum theory of fracture which describes the fast propagation of cracks. The theory overcomes the usual problem of a finite time cusp singularity of the Grinfeld instability by the inclusion of elastodynamic effects which restore the selection of the steady state tip radius and velocity. Two different numerical approaches are presented to… (More)

The phase field method is a very powerful numerical method to solve moving boundary problems. Here we demonstrate how it can be applied to various processes involving sound propagation and fracture. This approach is related to a new theory of fracture which describes in particular the fast growth of cracks. We study the propagation of elastic waves, the… (More)

An approach to solve numerically transport equations for plasmas with spontaneously arising and arbitrarily located transport barriers, regions with a strongly reduced transfer of energy, is proposed. The transport equations are written in a form conserving heat flux and solved numerically by using piecewisely exact analytical solutions of linear… (More)
