The motivation to constant knowledge update is due to the dynamic scientific and technological progress, which affects the change of all spheres of human activity. Employees of many organizations are in need of both professional development as well as obtaining a new specialty in order to maintain and improve their own competitiveness. In these conditions, higher educational institutions focused on adults training, are looking for new ways that will improve the formation of adult students competence. The purpose of the article is to analyze the experience of modern technologies implementation in the process of adult education. The article reveals the possibilities of innovative educational technologies, their essence and role in modern professional education. The role of continuous adult students education is emphasized, their functions are highlighted. The authors have identified the features on which the teacher relies in the process of adults training, which helps to make the training more effective. The implementation of modern adult education is based on the following principles: problematical character (the teacher should remember that adult students may feel uncomfortable in a group, they may be unaccustomed to feel like students again, for this it is necessary to "immerse" them in favorable conditions of communication. Role-playing, "brain storm" (which is more often referred to as discussion technologies, but in gaming it also takes place), blitz games contribute to the removal of emotional tension and the formation of effective cognitive motivation; the principle of dialogical communication.The study conducted among students of professional development courses from the age of 32 to 45 showed the need for further introduction of modern educational technologies in adult education. Their capabilities make the learning process more intense, active, and at the same time contribute to the rapid achievement of positive results

Preparation, Surface active properties, and Anticorrosion Application of some novel surfactants based on cottonseed oil and diethanolamine on carbon steel in CO2 environments

Novel surfactants were synthesized based on cottonseed oil and diethanolamine and the structures of these compounds were confirmed by FTIR spectroscopy. The surface and thermodynamic properties of these compounds have been investigated. The corrosion behavior of the synthesized surfactant corrosion inhibitors was evaluated by using potentiodynamic (Tafel) polarization curves, linear polarization resistance corrosion rate techniques. The experimental results showed that these inhibitors revealed a very good corrosion inhibition even at low concentrations. The protection efficiency increased with increasing inhibitor concentration, getting maximum values ranged between 87.37 and 97.91 % at 100 ppm after 20 hour of exposure. The adsorption process was found to obey the Langmuir adsorption isotherm

Performance of a plastic scintillator developed using styrene monomer polymerization

This paper presents a newly developed plastic scintillator produced in collaboration with Turkiye Energy, Nuclear and Mineral Research Agency (TENMAK). The scintillator is manufactured using thermal polymerization of commercially available styrene monomer. The absorption spectrum of the scintillator exhibited two absorption bands at 225 nm and 340 nm, with an absorption edge observed at 410 nm. The wavelength of the emitted light was measured in the range of 400-800 nm, with a maximum intensity at 427 nm. Monoenergetic electrons from the 137Cs source were used to evaluate the characteristics of the new scintillator, particularly its light yield. As the light readout the MAPD-3NM type silicon photomultiplier array (4 x 4) with an active area of 15 x 15 mm2, assembled using single MAPDs with an active area of 3.7 x 3.7 mm2, was used. The light yield of the scintillator was determined to be 6134 photons/MeV. In addition, the efficiency of the scintillator for gamma rays with an energy of 662 keV was found to be approximately 1.8 %. A CmBe neutron source was employed to evaluate its fast neutron detection performance. However, neutron/gamma discrimination using pulse shape discrimination (charge integration) method was not observed. The results demonstrate the potential of a newly produced plastic scintillator for various applications, particularly in radiation monitoring and detection systems.Comment: 7 pages, 7 figure

Современная тактика лечения злокачественных глиом головного мозга и случай полного ответа опухоли на фоне длительного приема бевацизумаба

Gliomas are common primary brain tumors in adults. This high degree of glioma malignancy is characterized by a disappointing outlook, despite the modern approaches to treatment. Therefore cases of prolonged relapse-free period of the disease, as well as treatment regimen and control regimen concerning gliomas with high degree of anaplasia are of exceptional interest. Even more exceptionally interesting is the drug bevacizumab, which in our clinical practice allowed to provide the patient with the diseasefree high-grade glioma from 2012 year to the present. Глиомы являются широко распространенными первичными опухолями головного мозга у взрослых. При этом глиомы высокой степени анаплазии характеризуются неутешительным прогнозом, несмотря на современные подходы к лечению. В связи с этим безусловный интерес представляют случаи длительного безрецидивного течения заболевания, применяемые схемы лечения и контроля над глиомами высокой степени анаплазии. Исключительный интерес представляет препарат бевацизумаб, который в нашей клинической практике позволил обеспечить пациенту безрецидивный период при глиоме высокой степени злокачественности с 2012 года по настоящее время.

Нейроэндокринные опухоли мочевыделительной системы: обзор литературы

Most often, neuroendocrine carcinoma (NEC) is found in the gastrointestinal tract, broncho-pulmonary system, but they can also occur in other organs, such as the kidney, bladder, which is of most interest because of the rarity of this pathology. Until recently, there was not even a proper morphological classification for kidney NEC, and among some histological types, such as large cell neuroendocrine carcinoma of the kidney, only about 7 cases were recorded, and independent bladder carcinoids, about 15 cases. Currently, there are no clinical and morphological features of the NEC of the kidney and bladder, fundamentally distinguishing them from other neuroendocrine tumors and “classic” cancer of the same localization. This article also provides the data of the N.N. Blokhin National Medical Research Centre of Oncology on the incidence of all malignant neoplasms of the urinary system.Наиболее часто нейроэндокринные неоплазии (neuroendocrine carcinoma, NEC) встречаются в желудочно-кишечном тракте и бронхолегочной системе, однако могут возникать и в других органах, таких как почки, мочевой пузырь, что представляет большой интерес ввиду редкости этих новообразований. До недавнего времени отсутствовала морфологическая классификация NEC почки. Среди некоторых гистологических типов, например таких как крупноклеточная нейроэндокринная карцинома почки, зафиксировано всего 7 случаев, а самостоятельных высокодифференцированных нейроэндокринных карцином мочевого пузыря – 15. В настоящее время не существует клинических и морфологических особенностей NEC почки и мочевого пузыря, принципиально отличающих их от других нейроэндокринных опухолей и «классического» рака той же локализации. В настоящей статье представлены сравнительные данные НМИЦ онкологии им Н. Н. Блохина по заболеваемости NEC и другими злокачественными новообразованиями мочевыделительной системы

Интернализация рекомбинантной имиглюцеразы в перитонеальные макрофаги мыши и фибробласты мыши линии L929

Enzyme replacement therapy (ERT) is one of the most efficient treatments for lysosomal storage diseases. Type 1 Gaucher disease is caused by β-glucocerebrosidase enzyme deficiency, which may be compensated for by intravenous infusions of imiglucerase—a recombinant enzyme. Imiglucerase targets macrophages and enters these cells via interaction with mannose receptors on the cell membrane. Characterisation of internalization of enzymes by target cells is important in the context of the development of new medicines and production of existing ERT medicines. The peritoneal and alveolar macrophages, as well as macrophages of the spleen of small laboratory animals (rats and mice) are widely used in such studies. However, isolation of cells from animal sources raises ethical issues, and therefore continuous mammalian cell lines may offer an attractive alternative. The aim of the study: to conduct comparative studies on the internalization of recombinant imiglucerase into mouse peritoneal macrophages and L929 mouse fibroblasts. Materials and methods: CerezymeR batches 7HV0913, C6214H05, 7HV0888 (Genzyme Ltd., UK); Glurazim batches 020416, 011117, 021117 (LLC “IBC “Generium”, Russia). We used peritoneal macrophages obtained from BALB/c mice and L929 mouse fibroblasts. The cells were cultured in DMEM/F12 complete growth medium with 10% fetal bovine serum. The activity of imiglucerase internalized into the cells was evaluated spectrophotometrically by hydrolysis of the artificial substrate—4-methylumbelliferyl-β-Dglucopyranoside. Results: the study compared internalization of recombinant imiglucerase (the active ingredient of CerezymeR and Glurazim) by mouse peritoneal macrophages and L929 mouse fibroblasts. It was demonstrated that the medicines activity in the lysates of peritoneal macrophages is comparable with that in the lysates of L929 mouse fibroblasts. Regardless of the model system, the activity of Glurazim stayed within the acceptable range (80–125%) established for biosimilar products. Conclusions: the experiments proved that L929 mouse fibroblasts could be recommended for assessment of internalization of recombinant imiglucerase.Фермент-заместительная терапия (ФЗТ) является одной из самых действенных при лечении болезней лизосомального накопления. Болезнь Гоше первого типа характеризуется недостатком нативного фермента β-глюкоцереброзидазы, который возмещают внутривенными инфузиями рекомбинантного фермента (имиглюцераза). Клетками-мишенями имиглюцеразы являются макрофаги, в которые фермент проникает посредством взаимодействия с рецепторами маннозы на клеточной мембране. Оценка интернализации ферментов клетками-мишенями представляет интерес при разработке новых и воспроизведении существующих препаратов для ФЗТ. Для этих исследований широко применяются перитонеальные и альвеолярные макрофаги, макрофаги селезенки мелких лабораторных животных (крыс и мышей). Однако получение таких клеток затрагивает этические вопросы использования лабораторных животных. Альтернативой являются перевиваемые клеточные линии млекопитающих. Цель работы: провести сравнительные исследования интернализации рекомбинантной имиглюцеразы в перитонеальные макрофаги мыши и фибробласты мыши линии L929. Материалы и методы: Церезим®, серии 7HV0913, C6214H05, 7HV0888 (Джензайм Лтд., Великобритания); Глуразим, серии 020416, 011117, 021117 (ООО «МБЦ «Генериум», Россия). В работе использовали перитонеальные макрофаги, полученные от мышей линии BALB/c, и фибробласты мыши линии L929. Клетки культивировали в полной ростовой среде ДМЕМ/Ф12 c добавлением 10% сыворотки плода крупного рогатого скота. Активность имиглюцеразы, проникшей в клетки, оценивали спектрофотометрически по гидролизу искусственного субстрата 4-метилумбеллиферил-β-D-глюкопиранозида. Результаты: представлены данные сравнительной оценки интернализации рекомбинантной имиглюцеразы, действующего вещества препаратов Церезим® и Глуразим, перитонеальными макрофагами мыши и клетками фибробластов мыши линии L929. Показано, что активность препаратов в лизатах перитонеальных макрофагов сопоставима с их активностью в лизатах клеток фибробластов мыши линии L929, при этом активность разработанного препарата Глуразим независимо от типа клеток, была в границах допустимого диапазона (80–125%), установленного для биоподобных препаратов. Выводы: экспериментально доказано, что фибробласты мыши линии L929 могут быть рекомендованы для оценки интернализации рекомбинантной имиглюцеразы

RESULTS IN PHYSICS

Radiological parameters of composite filler, zirconium and acrylic coating materials used in dental treatment are determined. Mass attenuation coefficients (mu(m)) of these materials have been experimentally determined for 9 different gamma energies emitting from Ra-226 and Eu-152 radioactive sources by using gamma spectrometry system with (3 '' x 3 '') NaI(Tl) detector. Effective atomic and electron numbers (Z(eff), N-eff), atomic and electronic cross sections (sigma(t,a) and sigma(t,el)) have been also obtained for these materials. The obtained results were compared with the NIST database and EGSnrc Monte Carlo (MC) code. It is found that general trends of these parameters are consistent with the literature. The maximum attenuation occurs at 122 keV and it has been found for 1 mm thick samples that 21%, 10% and 2% of the incident radiation have been absorbed by the zirconium, composite and acrylic samples, respectively
