Diabetes mellitus(DM) is the third most common noninfectious disease leading to early disability and high mortality. Moreover, the number of patients is growing every year. The main symptom of DM is hyperglycemia. Increased levels of blood glucose activate polyol, hexosamine, and protein kinase metabolic pathways cause the intensification of non-enzymatic glycosylation and nitration of macromolecules. This, in turn, leads to the development of oxidative and nitrative stresses and secondary complications, such as different kinds of microand macroangiopathies. Metabolic disorders caused by insulin deficiency in diabetes significantly impede the functioning of a homeostasis system, which change the physical, biochemical, morphological, and functional properties of blood cells. As a result, the oxygen-transport function of red blood cells(RBCs), rheological properties of the blood, and functions of immunocompetent cells as well as the process of apoptosis are primarily affected. Modern pharmacotherapy focuses on the search for new preparations that aim to decrease blood glucose levels. Undesirable side effects and adverse reactions caused by synthetic medicines led to the search and investigation of new preparations of natural origin. Medicinal mushrooms play an important role among such new preparations. They are a source of a large number of high-and lowmolecular compounds with pronounced biological effects. Our investigations show pronounced hypoglycemic and anti-anemic action of submerged cultivated mycelium powder of medicinal mushrooms Agaricus brasiliensis(A. brasiliensis) and Ganoderma lucidum(G. lucidum) on streptozotocin-induced DM in rats. Also, we showed that mycelium powders have membrane protective properties as evidenced by the redistribution of RBC populations towards the growth of full functional cell numbers.

The East African Rift system （EARS） provides a unique system with the juxtaposition of two contrasting yet simultaneously formed rift branches, the eastern, magma-rich, and the western, magma-poor, on either sides of the old thick Tanzanian craton embedded in a younger lithosphere. Data on the pre-rifr, syn-rift and post-rift far-field volcanic and tectonic activity show that the EARS formed in the context of the interaction between a deep mantle plume and a horizontally and vertically heterogeneous lithosphere under far-field tectonic extension. We bring quantitative insights into this evolution by implementing high-resolution 3D thermo-mechanical numerical deformation models of a lithosphere of realistic rheology. The models focus on the central part of the EARS. We explore scenarios of plumelithosphere interaction with plumes of various size and initial position rising beneath a tectonically pre-stretched lithosphere. We test the impact of the inherited rheological discontinuities （suture zones） along the craton borders, of the rheological structure, of lithosphere plate thickness variations, and of physical and mechanical contrasts between the craton and the embedding lithosphere. Our experiments indicate that the ascending plume material is deflected by the cratonic keel and preferentially channeled along one of its sides, leading to the formation of a large rift zone along the eastern side of the craton, with significant magmatic activity and substantial melt amount derived from the mantle plume material. We show that the observed asymmetry of the central EARS, with coeval amagmatic （western） and magmatic （eastern） branches, can be explained by the splitting of warm material rising from a broad plume head whose initial position is slightly shifted to the eastern side of the craton. In that case, neither a mechanical weakness of the contact between the craton and the embedding lithosphere nor the presence of second plume are required to produce simulations that

Empty nose syndrome (ENS) is a rare complication that develops after partial orcomplete turbinectomy. The main feature of ENS is paradoxical nasal obstructionfeeling despite objectively wide nasal airway. ENS pathogenesis is multifactorialand includes changes in laminar physiological airflow, disruption of mucosafunctions and deficient neural sensation. This leads to the development of ENSsymptomatology such as dyspnea, nasal dryness, nasal burning, nasalobstruction, feeling of suffocation and even comorbid psychiatric disorders thatsignificantly impairs life quality. Specific effective treatment of ENS does not existup to date. In this review we outline existing biomaterial for surgical reconstitutionof nasal anatomy and discuss the perspective of stem cell-based technologiesin ENS management. The main focus is directed to justification ofrationality application of adult mesenchymal stem cells (MSCs) from differenttissues origin and neural crest-derived stem cells (NCSCs) based on their intrinsicbiological properties. MSCs transplantation may stimulate mucosa tissueregeneration via trophic factors secretion, direct transdifferentiation into epithelialcells and pronounced immunosuppressive effect. From the other hand, NCSCsbased on their high neuroprotective properties may reconstitute nerve structureand functioning leading to normal sensation in ENS patients. We postulate thatapplication of cell-based and tissue-engineered products can help to significantlyimprove ENS symptomatology only as complex approach aimed at reconstitutionof nasal anatomy, recovery the nasal mucosa functionality and neural tissuesensation.
