    Aim. Development of an easy-to-use colorimetric sensor system for fast and accurate detection of phenol in envi- ronmental samples. Methods. Technique of molecular imprinting, method of in situ polymerization of molecularly imprinted polymer membranes. Results. The proposed sensor is based on free-standing molecularly imprinted polymer (MIP) membranes, synthesized by in situ polymerization, and having in their structure artificial binding sites capable of selective phenol recognition. The quantitative detection of phenol, selectively adsorbed by the MIP membranes, is based on its reaction with 4-aminoantipyrine, which gives a pink-colored product. The intensity of staining of the MIP membrane is proportional to phenol concentration in the analyzed sample. Phenol can be detected within the range 50 nM–10 mM with limit of detection 50 nM, which corresponds to the concentrations that have to be detected in natural and waste waters in accordance with environmental protection standards. Stability of the MIP-membrane-based sensors was assessed during 12 months storage at room temperature. Conclusions. The sensor system provides highly-selective and sensitive detection of phenol in both mo- del and real (drinking, natural, and waste) water samples. As compared to traditional methods of phenol detection, the proposed system is characterized by simplicity of operation and can be used in non-laboratory conditions.ΠœΠ΅Ρ‚Π°.

    Biosensors based on conductometric detection

    No full text
    The present paper is a self-review on the development of about 20 conductometric biosensors based on planar electrodes and containing different biological material (enzymes, cells, antibodies), bio-mimics or synthetic membranes, including Imprinting polymers, as a sensitive element. Highly specific, sensitive, simple, fast and cheap determination of different analytes makes them promising for needs of medicine, biotechnology, environmental control, agriculture and food industry. Non-specific interference of back-ground ions may be overcome by the differential mode of measurement, the usage of rather concentrated sample buffer and additional negatively or positively charged membranes, which decrease buffer capacity influence and extend a dynamic range of sensors response. For development of easy-to-use small conductometric immunosensors several approaches seem to be promising: i) the usage of polyaniline as electroconductive label for antibodies detection in competitive electroimmunoassay; ii) the elaboration of multilayer structures with phtalocyanine films; iii) the usage of acrylic copolymeric membranes. The advantages and disadvantages of conductometric biosensors created are discussed. For future commercialisation our effort are aimed to unite a thin-film technology with membranes deposition and to find the ways of membrane stabilisation, including bio-mimics creation, utilisation of bioaffinity polymeric membranes, imprinting polymers etc.Огляд присвячСно Π°Π½Π°Π»Ρ–Π·Ρƒ власних Ρ€ΠΎΠ±Ρ–Ρ‚ Π· Ρ€ΠΎΠ·Ρ€ΠΎΠ±ΠΊΠΈ близько 20 ΠΊΠΎΠ½Π΄ΡƒΠΊΡ‚ΠΎΠΌΠ΅Ρ‚Ρ€ΠΈΡ‡Π½ΠΈΡ… біосСнсорів Π½Π° основі ΠΏΠ»Π°Π½Π°Ρ€Π½ΠΈΡ… Π΅Π»Π΅ΠΊΡ‚Ρ€ΠΎΠ΄Ρ–Π² Ρ‚Π° Ρ€Ρ–Π·Π½ΠΎΠΌΠ°Π½Ρ–Ρ‚Π½ΠΎΠ³ΠΎ Π±Ρ–ΠΎΠ»ΠΎΠ³Ρ–Ρ‡Π½ΠΎΠ³ΠΎ ΠΌΠ°Ρ‚Π΅Ρ€Ρ–Π°Π»Ρƒ (Ρ„Π΅Ρ€ΠΌΠ΅Π½Ρ‚ΠΈ, ΠΊΠ»Ρ–Ρ‚ΠΈΠ½ΠΈ, Π°Π½Ρ‚ΠΈΡ‚Ρ–Π»Π°), синтСтичних ΠΌΠ΅ΠΌΠ±Ρ€Π°Π½ як Ρ‡ΡƒΡ‚Π»ΠΈΠ²ΠΈΡ… Π΅Π»Π΅ΠΌΠ΅Π½Ρ‚Ρ–Π².

    Chronic inflammation is one of the recognized factors contributing to the onset and progression of malignant neoplasms. At the systemic level, a chronic inflammatory process is accompanied by an increased levels of inflammatory mediators and a change in hematological parameters of peripheral blood. According to numerous clinical studies, the change in the ratio of blood cell populations in cancer patients is an independent prognostic factor in malignant tumors of various localizations. This review is devoted to hematological parameters of the systemic inflammatory response (SIR) in breast cancer (BC). The review presents the characteristics of blood cells used for calculations of hematological indices (neutrophils, lymphocytes, monocytes, platelets); approaches for assessing SIR using these indices (NLR, PLR, LMR, etc.); comparative analysis of data on the association of the hematological indices with the clinical and morphological features of BC, patient survival and tumor response to chemotherapy. The data indicating the benefit of SIR hematological markers investigation during monitoring after treatment are summarized. Complex algorithms, including clinical, morphological and hematological factors, which are proposed to improve the quality of prognosis assessment, are considered. The information accumulated to date suggests that hematological indices reflecting SIR activity in BC patients can serve as additional independent prognostic factors.

    Chronic inflammation caused by exposure to external or internal factors increases the risk of developing malignancies and promotes tumor progression due to the influence on the key elements of carcinogenic mechanisms. At the system level signs of a chronic inflammation are manifested by an increase of inflammatory mediators and acute phase proteins levels in the blood, a change in the ratio of circulating leukocyte populations, and disturbances in the hemostasis system. This review is devoted to serum and hematological parameters of the systemic inflammatory response (SIR) in breast cancer (BC). The first part of the review outlines general concept about the role of inflammatory factors in the development of malignant tumors. It provides information on the most well studied serum inflammatory markers in breast cancer: cytokines, including interleukin-6 (IL-6), interleukin-8 (IL-8), tumor necrosis factor-alpha (TNF-), as well as C-reactive protein (CRP). The main properties of these polypeptides, which link them with tumor-promoting inflammation, are considered. An analysis of the data on the clinical significance of the serum level of cytokines and CRP in breast cancer accumulated to date is presented. Correlations of the elevated levels of the serum inflammatory markers with clinical and morphological characteristics of the disease, tumor response to chemotherapy, overall and relapse-free survival of patients indicate the feasibility of in-depth investigation of the issue for the purpose of the practical application of the systemic inflammatory markers as predictive and prognostic indicators in BC.Π₯роничСскоС воспалСниС, Π²Ρ‹Π·Π²Π°Π½Π½ΠΎΠ΅ воздСйствиСм Π²Π½Π΅ΡˆΠ½ΠΈΡ… ΠΈΠ»ΠΈ Π²Π½ΡƒΡ‚Ρ€Π΅Π½Π½ΠΈΡ… Ρ„Π°ΠΊΡ‚ΠΎΡ€ΠΎΠ², ΡƒΠ²Π΅Π»ΠΈΡ‡ΠΈΠ²Π°Π΅Ρ‚ риск развития злокачСствСнных Π½ΠΎΠ²ΠΎΠΎΠ±Ρ€Π°Π·ΠΎΠ²Π°Π½ΠΈΠΉ ΠΈ способствуСт ΠΎΠΏΡƒΡ…ΠΎΠ»Π΅Π²ΠΎΠΉ прогрСссии, оказывая ΠΏΡ€ΠΎΠΌΠΎΡ‚ΠΈΡ€ΡƒΡŽΡ‰Π΅Π΅ дСйствиС Π½Π° Π²Π΅Π΄ΡƒΡ‰ΠΈΠ΅ патогСнСтичСскиС звСнья ΠΊΠ°Π½Ρ†Π΅Ρ€ΠΎΠ³Π΅Π½Π΅Π·Π°.

    SCIENTIFIC SUBSTANTIATION OF THE CONCEPTION OF CONTINUOUS ECONOMIC EDUCATION DEVELOPMENT

    No full text
    The Conception of continuous economic education development developed by us is based on the idea of continuous education, in which economic education is considered as an important structural element in the conditions of the new Russian developing economy. As a result of Russia's transition to a market economy, there is an urgent need for economic training of specialists who successfully work in the new socio-economic conditions, quickly and adequately responding to the changing market conditions. Economic education is aimed at the formation of economic competencies (key, professional and additional), and economic training is carried out in order to: the formation of economic thinking; development of business qualities of an economically educated person; accumulation of knowledge in the field of economy, management, taxation. In the conditions of market type economy professional education is focused on formation of the competitive, demanded in the labor market specialist possessing necessary economic competences which are formed in the course of economic training and economic education including knowledge of the objective economic laws and categories system; formation of economic competences and their realization in economic behavior; development of business qualities of the economically educated person; accumulation of knowledge in the field of economy, management, and taxation. The analysis of the classifications of competencies on various grounds allowed us to develop a structure of economic competence of students, including key, professional, and additional economic competences. The Conception of continuous economic education development developed by us takes into account the idea of continuing education, in which continuing economic education becomes an important structural element of vocational education in the conditions of the new Russian developing economy

    Introduction. The quality of professional education is a complex multi-level and dynamic system of qualities oriented on preparing a graduate who is in demand in the labor market. Research Methodology. The article's authors share P.F. Drucker's point of view, who believed that a system management should go in accordance with the plurality of its goals, and the efficiency of this process is measured, alongside with other factors, by the balance of the organizational goals. Research Results. The educational system of higher school is a kind of social economical system functioning on the scale of: micro-level (an educational institution); meso-level (a regional educational system); national level (the educational system of the Russian Federation); world level (global educational space). Discussion. In the Russian Federation, state control over statutory compliance in the higher school rests with the federal center and strictly follows timeframes. However, control and estimating procedures are neither comprehensive nor free from drawbacks. Besides, the process of state control over the education quality depends on a number of factors. Conclusion. Lack of due attention to the problems of education quality can lead to certain disproportions in the education services market. Β© 2018

    Clinical significanse of prostate-specific antigen in breast cancer patients

    No full text
    Background. Prostate-specific antigen (PSA) is predominantly produced by prostate epithelium, however, other tissues can serve as its minor sources in both men and women, including breast tissue. In women, elevated serum PSA levels have been described in different physiological and pathological conditions, including benign breast diseases and breast cancer (BC). PSA is considered as a potential serum tumor marker for BC, but evidences of its possible clinical significance are insufficiently convincing. Aim of the study: investigation of PSA levels in female BC patients and assessment of perspectives of its study as a diagnostic tool for early detection of BC. Material and methods. Serum PSA levels were measured by chemiluminescence immunoassay (ARCHITECT, Abbott) in 99 female patients with histologically confirmed BC (carcinoma in situ - 11, stage I - 56, stage IIA - 32) and 25 conditionally healthy female donors. Results. In the donor group, serum PSA was revealed in 22/25 (88,0 %) cases, and its mean level was 4.0 Β± 0.9 ng/l. In the group of BC patients, detectable PSA level was revealed in 68/99 (68.7 %) cases, and its mean level was 2.8 Β± 0.9 ng/l. Differences between groups of BC patients and donors in mean marker values were not statistically significant (p>0,05). Serum PSA levels were higher in young women: in the group of BC patients under 40 years old, percentage of PSA -positive cases was 89 %, in the group of patients over 50 years old - 60 %; in groups of donors under 40 and over 50 years old - 100 % and 80 %, respectively. In cases of in situ carcinoma, the mean serum PSA was higher than in cases with stages I and II (3.0 Β± 1.2 ng/l vs 1.9 Β± 0.3 ng/l and 1.6 Β± 0.3 ng/l, respectively; p>0,05). In the group of BC patients, no PSA levels were found to be dependent on the histological type, grade and molecular subtype of the tumor. Conclusion. The PSA level has no clinical significance in early stages of BC, since the proportion of cases with elevated PSA levels and it’s mean value in patients with early stages of BC don’t differ from those in the group of healthy women.

    KIM-1 (kidney injury molecule 1), a marker of acute kidney injury, is produced by epithelial cells of renal proximal tubules. Elevated KIM-1 levels in urine and plasma are associated with renal cell carcinoma (RCC). The aim of this study was to compare the significance of non-normalized uKIM-1 values and those normalized to urine creatinine, as urinary biomarkers in RCC. The uKIM-1, urine creatinine and their ratio (uKIM-1/Cre) were studied in 118 RCC patients and 58 apparently healthy subjects. The median of uKIM-1 in the healthy group was 0.71 ng/ml (1st and 3rd quartiles were 0.35 and 1.23, respectively) and in RCC patients it was 2.36 (1.43; 5.93) ng/ml. The medians of uKIM-1/Cre were 0.77 (0.49; 1.18) and 2.42 (1.41; 4.61) ng/mgCre, respectively. Stage I RCC is statistically significantly different from stages II-III and stage IV using uKIM-1/Cre values (p = 0.0056 and p = 0.0012, respectively); using uKIM-1 values significant differences occur only when comparing stages I and IV (p = 0.015). In both healthy individuals and RCC patients, uKIM-1/Cre levels were slightly lower in subgroups younger than 50 years than in subgroups older than 50 years, whereas a similar trend was observed for uKIM-1 only in patients. In healthy men and male patients, uKIM-1 levels were higher than in the corresponding groups of women (the differences were not statistically significant), but the use of uKIM-1/Cre values eliminated the gender differences. A high correlation was found between the concentrations of uKIM-1 and urine creatinine in three healthy subjects followed up for 3 weeks (Spearman's correlation coefficients were 0.758, 0.825 and 0.933, respectively). The data obtained are clear evidence of the need for normalization uKIM-1 to urine creatinine in RCC patients

    DESIGN CULTURE OF R&D PROJECT SPECIALIST IN THE LIGHT INDUSTRY

    No full text
    A fashion designer (FD) is a person who plays a key role in creating new variants of clothing, shoes, hats and other things of this kind (including accessories). The professional patterns proposed by this worker determine the fit, the potential demand and other important characteristics of the product. Previously, the designer was a specialist who combined a number of professional functions: he/she was responsible for the choice of fabric, the style, the cutting and the sewing. However, in the future many tasks were distributed among other employees: designer, cutter and tailor. Therefore, the FD's functions have significantly decreased. Currently his/her duties include studying fashion trends, formulating fresh ideas and creating sketches. The technologist processes fabrics, modernizes the production process and improves the tailoring technique. The constructor deals with drawings, i.e. is involved in both technical and artistic aspects of the activity. As a rule, these specialists work together in a team, making a common contribution to the creation of new collections. As for the FD, in most cases he/she is engaged in a ready-made sketch developed by the constructor. In other words, the former is obliged to realize the latter's creative idea, turn it into a tangible and visible object with the lowest material and technical costs. The FD decides which fabric should be used for a particular model, deals with patterns and templates, provides various approaches to the implementation of the original plan. Thus, we are talking about activities of technical nature with an element of creativity, which requires special education and specific professional skills
