Physical Fitness of Students who Go in for Boxing in the Process of their Physical Training
Physical and special physical fitness of first and second year students which go in for boxing in the process of their physical training during one and two years, respectively, is defined here. The research involved 108 students: 54 students from first year and 54 students from second year, which were tested during the year (at the beginning and at the end). The following types of testing were used: standing long jump, lying dip up for 20 sec and 1 min, speed – 100 m running, endurance – running 3000 m, rope jumping (quantity per 1 min) and special physical fitness was determined by maximum quantity of left and right punches during 15 sec. There positive dynamics and growth of all physical fitness indicators of students who went in for boxing during the first year was defined. The students who went in for boxing for the second year showed better results and their dynamics (in addition to indicators of 100 m running speed)
Modelling of diffusion saturation of (alpha+beta) titanium alloy by oxygen in rarefied gaseous medium
Антикризисное управление банком: моделирование привлечения денежных средств для поддержания его ликвидности
The mathematical model of a borrowing money contour to cover bank's liquidity needs taking into account positive feedback loop between interest expense and the borrowing money amount is developed. The examples of valuation of the borrowing amount and the survival time are given. The model is useful to assess the bank’s liquidity under normal and stress scenarios
Modeling of diffusion saturation of titanium by nitrogen taking into consideration structural and phase transformations
Kinetic peculiarities of two-component diffusion saturation of titanium under rarefied nitrogen-oxygen-containing medium
The activity of proliferation and apoptosis of thyrocytes in the thyroid tissue of patients of nodular goiter with autoimmune thyroiditis considering the polymorphism of the BCL-2 (RS17759659), CTLA-4 (RS231775), APO-1/FAS (RS2234767) genes
Nodular goiter with autoimmune thyroiditis is one of the most important problems of modern endocrinology, with inadequately studied
etiological and pathogenic mechanisms of development. It is characterized by the lack of objective and reliable diagnostic methods,
effective treatment methods, uncertain therapy or indications for the choice of treatment methods. A total we have examined 125 patients
who were operated for a nodular endemic goiter with autoimmune thyroiditis. Investigated the activity of proliferation and apoptosis of
thyrocytes in the thyroid tissue of patients of nodular goiter with autoimmune thyroiditis considering the polymorphism of the bcl-2
(rs17759659), ctla-4 (rs231775), apo-1/fas (rs2234767) genes. The expression/density markers - Fas/ FasL, Bcl-2, p53 and Ki-67 on the
thyrocytes in the lymphoid infiltration and destruction areas, as well as in normal thyroid tissue (as a control) were studied. The number
of immunoreactive cells, which expressed the above-mentioned regulating apoptosis and proliferation markers in NGAIT patients,
depending on the genes polymorphism BCL-2 (rs17759659), CTLA-4 (rs231775) and APO-1/Fas (rs2234767) were counted. It was
found that in NGAIT patients a few links of programmable thyroid cell killing of Fas-induced apoptosis were activated, and associated
with the polymorphic cite of BCL-2 (rs17759659) gene and almost 6 times weaker with CTLA-4 (rs231775) gene, through enhanced
expression of Fas and Fas L on the cells surface in lymphoid infiltration and destruction areas (stronger in GG genotype carriers of BCL2 gene)
Changes in the vulnerability of clinical manifestations of thyrotoxic cardiomyopathy as indicators of remote results of surgical treatment in patients with toxic goiter
The aim of the work – improvement of the evaluation method of remote results of surgical treatment in patients with toxic goiter, taking into account the changes in the severity of clinical manifestations of thyrotoxic cardiomyopathy Materials and methods. The research was conducted in 150 patients operated for toxic goiter of moderate severity (48) and severe (102). The method of estimation of remote results of surgical treatment, taking into account the regression of signs of thyrotoxic cardiomyopathy and gradation and division into good, satisfactory, unsatisfactory and ineffective treatment, was developed. Results and discussion. A good remote outcome of surgical treatment of thyrotoxicosis was achieved in 26 (54.2 %) patients with moderate thyrotoxicosis and in 9 (8.8%) patients with severe thyrotoxicosis, satisfactory in 21 (43.7 %) and 36 (35, 3%) cases respectively and unsatisfactory – in 1 (2.0 %) and 33 (32.4 %). Ineffective surgical treatment was recognized in 24 (23.5 %) patients. Unsuccessful results and ineffective surgical treatment of toxic goiter were found in patients with severe heart rate rhythm disorders, structural and functional changes in the cardiac muscle and functional classes II and III. Conclusions. Long-term results of surgical treatment of patients with toxic goiter are determined by the severity of thyrotoxic cardiomyopathy. In cases of severe thyrotoxicosis, the question of the need for surgical treatment should be put in the development of severe heart rhythm disorders and structural and functional changes in the heart muscle
Drug therapy in autoimmune thyroiditis
Background. Autoimmune thyroiditis (AIT) is one of the unsolved problems of modern endocrinology, the etiology and pathogenesis being still insufficiently known.
Objectives. To study the effects of substitution, antioxidant and lymph-drainage therapy on the structure and function of the thyroid gland in patients with AIT and hypothyroidism.
Methods. We have identified 2 groups of patients with AIT and subclinical hypothyroidism. The first group – control group – included 20 patients who received substitution therapy with thyroxine. The second group included 33 patients who received a comprehensive treatment with thyroxine, alpha lipoic acid and Lymphomyosot.
Results. The use of substitution therapy with thyroxine and the proposed antioxidant and lymph drainage therapy in patients with AIT led to the improvement of the structure of the gland, reduced the activity of peroxide oxidation processes and the activity of pro-inflammatory cytokines, increased the level of antioxidant defense enzymes, normalized the number of aniline-positive lymphocytes, improved the lymphatic drainage function of the gland. Our results sustain the effectiveness of the proposed method of complex treatment in patients with autoimmune thyroiditis
