Bioactivity Features of a Zn-1%Mg-0.1%Dy Alloy Strengthened by Equal-Channel Angular Pressing.

The structure, phase composition, corrosion and mechanical properties, as well as aspects of biocompatibility in vitro and in vivo, of a Zn-1%Mg-0.1%Dy alloy after equal-channel angular pressing (ECAP) were studied. The structure refinement after ECAP leads to the formation of elongated α-Zn grains with a width of ~10 µm and of Mg- and Dy-containing phases.

Beneficial Effect of the New sp. Strain on Development of Blueberry Microclones in the Process of Their Adaptation.

The paper searches for new solutions for the development of highbush blueberry orchards ( L. (1753)) in Western Siberia. All species of the genus display special symbiotic mycorrhizal associations with root systems-ericoid mycorrhiza, which essentially enhances the formation of adventitious and lateral roots.

Somatic Mutation Profiling in Head and Neck Paragangliomas.

Context: Head and neck paragangliomas (HNPGLs) are rare neoplasms with a high degree of heritability. Paragangliomas present as polygenic diseases caused by combined alterations in multiple genes; however, many driver changes remain unknown.

Objective: The objective of the study was to analyze somatic mutation profiles in HNPGLs.

[Venous thromboembolic complications in patients with intracerebral hemorrhage].

Objective: To evaluate the effectiveness and safety of various heparin therapy regimens for venous thromboembolic complications in patients with acute cerebral circulatory disorders of the hemorrhagic type.

Material And Methods: In a prospective single-center study, treatment results of 62 patients with hypertensive brain hematoma were analyzed. All patients were divided into two comparable groups: the group of «very early» prophylactic heparin therapy or the first 48 hours from the moment of the disease (=35) and the group of «early» prophylactic heparin therapy, or later than 48 hours from the moment of the intracerebral hematoma development (=27).

Immunohistochemistry and Mutation Analysis of Genes in Carotid Paragangliomas.

Carotid paragangliomas (CPGLs) are rare neuroendocrine tumors often associated with mutations in genes. The immunohistochemistry of succinate dehydrogenase (SDH) subunits has been considered a useful instrument for the prediction of mutations in paragangliomas/pheochromocytomas. We compared the mutation status of genes with the immunohistochemical (IHC) staining of SDH subunits in CPGLs.
