Aim. The aim of study was to examine the relationship between serum and mammary gland homocysteine levels with the carrier of separate SNP (single nucleotide polymorphism) genes of the folate metabolism system in patients with proliferative diseases and breast cancer. Methods and results. The study included 182 patients with proliferative diseases of the mammary gland in transbaikalia. The control group included 144 women who did not have oncological diseases. The serum homocysteine level and the supernatant of the mammary tissue homogenate were evaluated by high performance liquid chromatography. Genotyping for the detection of polymorphism MTHFRΠ‘677T, MTHFRΠ1298C, MTRA2756G, MTRRA66G was carried out by polymerase chain reaction with the detection of the amplification product in real time. In the course of molecular genetic testing in patients with proliferative diseases of the mammary gland, there was found: 1) the absence of an explicit association of the carriage of genetic polymorphism MTHFRΠ‘677T, MTHFRΠ1298C, MTRA2756G and MTRRA66G with serum homocysteine concentration, however, comparative hyperhomocysteinemia and, to a lesser extent, in women with the benign breast diseases; 2) the highest homocysteine content in the blood in patients with breast cancer whose genotype was characterized by combinations of polymorphic alleles MTR2756G x MTRR66G; 3) that the MTR2756A allele and genotype MTHFR1298AC, especially their combination of MTHFR1298AC x MTR2756A, increase the risk of developing benign breast formations; 4) the effect of the risk alleles MTR2756G and MTRR66GON the concentration of homocystein in the tumor tissue of the mammary gland. Conclusion. These patterns indicate a certain contribution of the polymorphisms studied, especially their additive effect, both in the development of proliferative diseases of the mammary gland and in the possible potentiation of prothrombotic effects in these patients against the background of tumor progression and homocysteine metabolism disorders.Π¦Π΅Π»Ρ.

This article analyzes the frequency of polymorphisms of hemostasis system and folate cycle protein genes associated with increased risk of thrombophilia based on the results of CHGMA (Chita State Medical Academy) genetic laboratory patients with reproductive health disorders. Method of research is allele-specific PCR. It was analyzed 1800 DNA samples. The most frequently mutations occur in the genes of receptors in the platelets and the folate cycle, mostly heterozygous substitution. Leiden mutation (F5) and prothrombin mutation (F2) are the most significant in the thrombophilia development and occur much less frequently. Only in one case revealed a homozygous mutation in the gene F2 and F5.Π Π΄Π°Π½Π½ΠΎΠΉ ΡΡΠ°ΡΡΠ΅ ΠΏΡΠΎΠ²Π΅Π΄Π΅Π½ Π°Π½Π°Π»ΠΈΠ· ΡΠ°ΡΡΠΎΡΡ Π²ΡΡΡΠ΅ΡΠ°Π΅ΠΌΠΎΡΡΠΈ ΠΏΠΎΠ»ΠΈΠΌΠΎΡΡΠΈΠ·ΠΌΠ° Π³Π΅Π½ΠΎΠ² ΡΠΈΡΡΠ΅ΠΌΡ Π³Π΅ΠΌΠΎΡΡΠ°Π·Π° ΠΈ Π±Π΅Π»ΠΊΠΎΠ² ΡΠΎΠ»Π°ΡΠ½ΠΎΠ³ΠΎ ΡΠΈΠΊΠ»Π°, Π°ΡΡΠΎΡΠΈΠΈΡΠΎΠ²Π°Π½Π½ΡΡ

Background. Imbalance of aminothiol metabolism is a potential risk factor for malignant transformation of cells and caner development, including breast cancer, which is the most commonly diagnosed cancer in the world. The purpose of the study was to summarize the available data on the characteristics of thiol metabolism as one of the factors contributing to the progression of breast cancer. Material and Methods. Data were searched from 1999 to 2022 using the Web of Science, Scopus, MedLine, The Cochrane Library, PubMed databases, which made it possible to assess the role of thiol-dependent metabolic disturbances in the regulation of tissue redox balance in breast cancer genesis. Results. The review considers the results of both our own data and international studies on breast cancer, which suggest that an imbalance of thiol compounds necessary to maintain a moderately reducing cellular environment that counteracts oxidative stress during cellular metabolism and detoxifcation under conditions of tumor progression can provoke reprogramming of the leading links of antiblastoma resistance, contributing to cancer progression. Conclusion. A more detailed study of the mechanisms of aminothiol metabolism in breast cancer emphasizes their particular importance for stabilizing the cellular genome and providing antitoxic protection of the cell, as well as understanding the important role of thiols as a coordination center in redox signaling. Disturbances at any stage of thiol metabolism can play an etiological role in oncogenetic pathologies, while the role of thiols as signaling molecules and the regulation of their metabolism should not be generalized for the entire group of diseases. Determination of serum markers of the redox state in patients with breast cancer, especially during antitumor therapy, can serve for an objective assessment of the effectiveness of treatment and the adaptive capabilities of the body, as well as predicting tumor growth and optimizing the program for screening and preventing cancer.ΠΠ²Π΅Π΄Π΅Π½ΠΈΠ΅.

Berry Phase of a Resonant State
We derive closed analytical expressions for the complex Berry phase of an
open quantum system in a state which is a superposition of resonant states and
evolves irreversibly due to the spontaneous decay of the metastable states. The
codimension of an accidental degeneracy of resonances and the geometry of the
energy hypersurfaces close to a crossing of resonances differ significantly
from those of bound states. We discuss some of the consequences of these
differences for the geometric phase factors, such as: Instead of a diabolical
point singularity there is a continuous closed line of singularities formally
equivalent to a continuous distribution of `magnetic' charge on a diabolical
circle; different classes of topologically inequivalent non-trivial closed
paths in parameter space, the topological invariant associated to the sum of
the geometric phases, dilations of the wave function due to the imaginary part
of the Berry phase and others.Comment: 28 pages Latex, three uuencoded postcript figure
Diffusion bonding of TiC or TiB reinforced Tiβ6Alβ4V matrix composites to conventional Tiβ6Alβ4V alloy
The diffusion bonding of conventional alloy Tiβ6Alβ4V (Ti-64) and composites of this alloy with 10% of TiC or TiB fabricated using blended elemental powder metallurgy was successfully carried out at 850β1000Β°C, with a holding time of 60βmin under 0.7β1.5βMPa pressure. The metallographic and electron backscattered diffraction studies as well as the bending and microhardness tests across the bonds are presented as the evidence of joint integrity. The selected experimental parameters do not cause undesirable structural changes (degradation) in the base metals adjacent to the bond interface. Particle reinforcement at βΌ10% did not appear to modify bonding parameters when compared to the unreinforced Ti-64 alloy
