Введение. Понятие «резистентность к ацетилсалициловой кислоте (АСК)» характеризуется как ее неспособность снижать продукцию тромбоксана А2 и ингибировать активацию и агрегацию тромбоцитов. Одним из методов оценки резистентности к АСК является определение концентрации 11-дегидротромбоксана В2 в моче. Целью нашего исследования являлось изучение взаимосвязи уровня 11-дегидротромбоксана В2 в моче и других клинико-лабораторных показателей с наличием в анамнезе неблагоприятных сердечно-сосудистых событий (инфаркта миокарда, ишемического инсульта) у пациентов со стабильной ишемической болезнью сердца (ИБС), получающих АСК. Пациенты и методы. В поперечное исследование включены 82 пациента со стабильной ИБС, получающих терапию аспирином в дозе 75-150 мг в сутки. В качестве маркера резистентности к АСК оценивался уровень 11-дегидротромбоксана В2 в моче. Статистический анализ включал в себя использование U-критерия Манна-Уитни, анализа ROC-кривых, многофакторной логистической регрессии. Результаты. Медиана 11-дегидротромбоксана В2 в моче у пациентов с неблагоприятными сердечно-сосудистыми событиями в анамнезе и без них составила 587,8 (Q1-Q3 512,8-800,3) пг/мг креатинина и 438,3 (Q1-Q3 337,6-577,9) пг/мг креатинина, соответственно (р=0,001). Пороговое значение уровня 11-дегидротромбоксана В2 в моче, которое прогнозировало высокий риск сердечно-сосудистых событий, составило 521,1 пг/мг креатинина, у 36 (43,9 %) пациентов концентрация исследуемого метаболита превышала полученное значение. В ходе регрессионного анализа построена модель, включающая количество тромбоцитов, уровень 11-дегидротромбоксана В2 в моче и наличие сахарного диабета 2 типа и характеризующая зависимость наличия в анамнезе неблагоприятных сердечно-сосудистых событий от указанных параметров. Чувствительность и специфичность полученной модели составили 55 % и 88,9 %, соответственно. Заключение. Результаты проведенного исследования свидетельствуют, что у пациентов со стабильной ИБС, перенесших сердечно-сосудистые события, антитромбоцитарный эффект аспирина слабее, чем у пациентов без перенесенного инфаркта миокарда и/или ишемического инсульта.

Biobased nanoemulsion for blocking COVID-19 from accelerating Alzheimer's disease
Краткое сообщение
An effective therapeutic strategy to delay dementia could be based upon nanotargeting drug(s), using lipid nanocarriers (i.e., biobased nanoemulsion technology), toward a major serum amyloid A (SAA) receptor responsible for certain proinflammatory, SAA-mediated, cell signaling events. For example, other investigators have already confirmed that SR-BI receptors (or its human ortholog CLA-1) function as proinflammatory cell-surface SAA receptors, and additionally report that various ligands for CLA-1/SR-BI "efficiently compete" with SAA for CLA-1/SR-BI binding. A similar benefit (of "competitive binding") may well accompany the clinical intravenous use of the ("HDL-like") lipid nanocarriers (i.e., biobased nanoemulsion [see above]), which have already been repeatedly described in the peer-reviewed literature as a targeted (and SR-BI mediated) drug-delivery agent. To conclude, the above-proposed "competitive binding", between SAA and such biobased nanoemulsion(s), could assist/enhance the protective (ordinarily anti-inflammatory) role of HDL - as well as provide targeted drug-delivery to the (human) brain cells bearing CLA-1/SR-BI receptors. The first resulting advantage is that this (intravenous) colloidal-nanocarrier therapeutic makes it possible for various cell types, all potentially implicated in Alzheimer's disease and/or (late-onset) dementia, to be simultaneously sought out and better reached for localized drug treatment of brain tissue in vivo. A second major advantage is that this therapeutic-target approach has particular relevance to the current COVID-19 human pandemic; namely, immune response and excessive inflammation in COVID-19 infection may accelerate the progression of brain inflammatory neurodegeneration which, if effectively halted, might play a major role in reducing Alzheimer's disease pathology.

Biochemical pathways of metabolic disorders in psoriasis
Статья обзорная
The development of metabolic disorders occurs in psoriasis: insulin resistance, systemic inflammation, atherosclerosis, oxidative stress and obesity. The paper presents pathological biochemical pathways of metabolic disorders development which is caused by common cytokine profile chara-cteristic for psoriasis and obesity and they are tumor necrosis factor alpha (TNF-α), interleukin-6 (IL-6), and interleukin-8 (IL-8). The following links play a role in the development of insulin resistance: insulin receptor (IRS-1) and insulin receptor substrate (SIR-1), glucose transporter protein (GLUT-4), also there is a decrease in the phosphatidylinositol 3-kinase pathway (PI3AKT) activity, and an increase in the mitogen activating protein kinase (MAPK) activity. Factors influencing the development of inflammation are discussed: IL-6, C-reactive protein, tissue plasminogen activator inhibitor (PAI-1), monocyte chemoattractant protein 1 (MCP-1), proinflammatory adipokines; processes of vascular inflammation development, atherosclerosis development and oxidative stress. This article discusses endocrine disruption of adipocytes in obesity and the influence of adipokines and inflammatory mediators synthesized by fat cells on psoriatic disease. Advanced glycation end products (AGEs), hyperhomocysteinemia (HHcy) due to vitamin B12 and folic acid deficiency, and a 5,10-methylfolate reductase (MTHFR) mutation are also important in the clinical manifestations of psoriasis. The possibility of assessing metabolic disorders and dysfunction of various organs by changes in the levels of metabolites in the blood and skin of patients with psoriasis is discussed.

COVID-19 и сопутствующая онкологическая патология: терапевтические возможности и сложности
Статья обзорная
Коронавирусная инфекция 2019 года (COVID-19) - это вирусное заболевание, вызываемое новым коронавирусом тяжелого острого респираторного синдрома, SARS-CoV-2, который поражает легкие инфицированных лиц. COVID-19 распространяется от человека к человеку посредством респираторных капель, выделяющихся при кашле или чихании инфицированного. Эпидемия COVID-19 началась в городе Ухань (Китай) в конце 2019 года. По состоянию на 29 сентября 2020 года более 235 стран, районов или территорий по всему миру сообщили в общей сложности о 33 441 919 подтвержденных случаях заболевания и о 1 003 497 подтвержденных смертях от COVID-19. Риску заражения подвержены люди любого возраста, но в большинстве случаев тяжелое течение заболевания наблюдается у людей старшей возрастной группы и при наличии сопутствующей патологии, которая снижает иммунитет, например, онкологических заболеваний. Данные многочисленных исследований позволяют предполагать, что пациенты со злокачественными новообразованиями могут быть подвержены более высокому риску тяжелого течения COVID-19 и летального исхода. Поэтому оказание онкологической помощи в условиях пандемии является сложной задачей и требует совместного междисциплинарного подхода для оптимального лечения онкологических больных в условиях стационара. В этом расширенном обзоре мы обсуждаем влияние пандемии COVID-19 на онкологических больных и оказание им медицинской помощи. Помимо этого, обзор содержит общие сведения о пандемии, вызванной SARS-CoV-2, характеристику генома вируса, описание патофизиологии COVID-19 и связанных с ней сигнальных путей, играющих важную роль при онкопатологии, а также информацию о вариантах использования противоопухолевых средств для лечения COVID-19.

Development of an algorithm for making management decisions based on situational analysis
Статья научная
This paper proposes an algorithm for making management decisions using a situational analysis in the aviation industry. The effectiveness of management decisions directly depends on the industry in which the organization operates, and the information on the basis of which this decision is made. The basis for developing solutions is analysis. Depending on the direction of the decision, the analysis is divided into managerial, diagnostic, financial, operational, situational. Each industry has its own limiting aspects that affect the implementation process and the outcome of the decision. In the course of diagnostics, as a rule, the main legislative restrictions or the advantages that companies need to take into account in order to maximize profits are revealed. To effectively diagnose the state of an enterprise, it is advisable to single out a number of analysis methods. In the process of developing the algorithm, the main methods of analysis and specific features of the industry were considered.

Статья научная
Communicating in a foreign language is impossible without mastering vocabulary. It is of special importance in English for Specific Purposes (further ESP) courses as requirements of modern realities in Kazakhstan force experts to know enough ESP vocabulary to be able to demonstrate their knowledge in their professional sphere. Since vocabulary plays such an important role in ESP courses it is essential to determine what strategies ensure effective teaching and learning it in specific groups of learners. This paper presents results of a study held on vocabulary teaching and learning strategies employed by ESP teachers and learners at L.N. Gumilyev Eurasian national university (further ENU) in Astana, Kazakhstan. An open-ended questionnaire and a semi-structured interview were conducted among 20 ESP teachers and 48 ESP students of L.N. Gumilyev ENU. The questions elicit not only teachers’ vocabulary teaching experiences and opinions about the most effective vocabulary teaching approaches but also the reasons for students’ vocabulary learning and using problems. During the interview students described their preferred vocabulary learning styles and confirmed the importance of learning vocabulary in ESP. The study determined the most effective ESP vocabulary teaching and learning strategies for teachers to use at L.N. Gumilyev Eurasian National University.
