A computer simulation study is made on mutual synchronization of auto-oscillations of epidermal cell density in psoriatic skin lesions under conditions of strong clipped noise. The initial model is a system of three ordinary nonlinear differential equations, presumably describing the ...

The distribution of an electric field in plant cells and zooblasts has been investigated during propagation of the action potential. The behavior of ions in the cytoplasm and in the extracellular fluid has been described with the equations of electric charge motion in electrolytes. It has ...

Treatment of barley plants with a supercritical fluid extract of amaranth led to an increase in parameter (F M − F T)/F T of the leaf slow fluorescence induction curve. Barley treated with the extract showed higher productivity and better crop indices.

Viscoelastic properties of relaxed rat papillary muscles in physiological hypertrophy (intensive swimming for 5 weeks) have been obtained. It has been ascertained that viscoelastic properties of hypertrophied muscles are not significantly distinguished from those of control papillary muscles. ...

NMR-spin echo method has been used to study spin-lattice relaxation time of protons T1 in plant and animal cells — muscle tissue of fish, the cells of which unlike plant cells have no developed system of vacuoles, plastids and a solid cell wall. According to the values of T1 time a new NMR ...

A theoretical model of propagation in the cytoplasm of self-consistent electromagnetic waves of the millimeter-infrared range has been developed, cytoplasmic ions surrounded by water “coats” being the main carriers of these waves. It has been discovered that not only own long-wavelength ...

Suppression of human tumor cell resistance to TRAIL-induced apoptosis in confluent cultures, using molecular target drugs (sorafenib and SAHA) at non-toxic concentrations was studied. Sorafenib, a multikinase inhibitor, and SAHA, an inhibitor of histone deacetylase, effectively suppressed ...

An assertion is substantiated that what is widely termed the chlorosomes of green bacteria are not bioparticles, but simply microscopic bacteriochlorophyll c crystals. Apparently, formation of a “chlorosome” represents the first, largely unsuccessful, evolutionary attempt to create a ...

A mathematical model of the air diffusion process through the water surface taking into account the reverse flow of bubbles was proposed. The numerical solving gives self-oscillation of the dissolved air concentration. Spectral density of these oscillations has the 1/f-noise form, which ...
