3. Evaluation of a New Vasculature by High Resolution Light Microscopy: Primo Vessel and Node

Abstract

The primo vascular system is composed of nodes and vessels. The bundle of sub-vessels of the promo vessel is laid into an external jacket composed of endothelial cells. The node is heterogeneous in nature, composed of twisted sub-vessel bundles that fill up nearly the entire node volume. The enlarged sub-vessel inside the node harbors microcells that express stem cells and stem cells niche markers. We conclude that these microcells are progenitors of multipotent stem cells and the nodes serve as the stem cell niches outside the bone marrow., Comment: 14 pages, 7 figures

4. Superconducting State and Phase Transitions

Author

Mnyukh, Yury and Vodyanoy, Vitaly

Subjects
Condensed Matter - Superconductivity
Abstract

From the days when superconductivity was discovered its science was entangled by the unresolved problem of the relationship between superconductive state, its crystal structure and its phase transitions. The problem was exacerbated by the adjacent scientific area - solid state phase transitions - that offered to divide phase transitions into first and second order. Adding to that the conclusion (turned out erroneous)on the structural identity of the superconductor and normal phases, the whole issue was uncertain and confusing. This article straights it out., Comment: 18 pages, 8 figures

Abstract

Erythrocytes and vesicles shed by erythrocytes from human and rat blood were collected and analyzed after temperature was elevated by physical exercise or by exposure to external heat. The images of erythrocytes and vesicles were analyzed by the light microscopy system with spatial resolution of better than 90 nm. The samples were observed in an aqueous environment and required no freezing, dehydration, staining, shadowing, marking or any other manipulation. Temperature elevation, whether passive or through exercise, resulted in significant concentration increase of structurally transformed erythrocytes (echinocytes) and vesicles in blood. At temperature of 37 oC, mean vesicle concentrations and diameters in human and rat blood were (1.50+-0.35)x10^6 and (1.4+-0.2)x10^6 vesicles/{\mu}L, and 0.365+-0.065 and 0.436+-0.03 {\mu}m, respectively. It was estimated that 80% of all vesicles found in human blood are smaller than 0.4 {\mu}m. Thermodynamic analysis of experimental and literature data showed that erythrocyte transformation, vesicle release and other associated processes are driven by entropy with enthalpy-entropy compensation. It is suggested that physical state of hydrated cell membrane is responsible for the compensation. The increase of vesicle number related to elevated temperatures may be indicative of the heat stress level and serve as diagnostic of erythrocyte stability and human performance., Comment: 18 pages, 7 figures, Submitted to the Journal of Thermal Biology on January 25, 2013

8. The physical nature of 'giant' magnetocaloric and electrocaloric effects

Author

Vodyanoy, Vitaly J. and Mnyukh, Yuri

Subjects
Condensed Matter - Materials Science
Abstract

Physical nature of "giant" magnetocaloric and electrocaloric effects, MCE and ECE, is explained in terms of the new fundamentals of phase transitions, ferromagnetism and ferroelectricity. It is the latent heat of structural (nucleation-and-growth) phase transitions from a normal crystal state to the orientation-disordered crystal (ODC) state where the constituent particles are engaged in thermal rotation. The ferromagnetism or ferroelectricity of the material provides the capability to trigger the structural phase transition by application, accordingly, of magnetic or electric field., Comment: 6 pages, 1 figure, new text formatting
