The study involved 91 patients (48 women and 43 men), aged from 18 to 70 years with GERD. All patients underwent the clinical dental examination according to a single scheme including general clinical manifestations (nausea, single vomiting, belching, heartburn, pain in the epigastrium and around the navel, and poor appetite) and dental manifestations of GERD. The objective assessment of the dental status of the examined patients included the measurement of the functional parameters of the mixed saliva, buffer capacity (BC) of saliva, and the detection of the nitric oxide metabolites (NOx) content in saliva from the right parotid salivary gland (“SRPSG”) and in blood serum using the indirect method based on the determination of the stable metabolites: nitrates and nitrites using the Griess reaction. It was established that salivation rate among patients with GERD with the prevailing of ACR and SACR was at the lower limit of normal values (0.32 + 0.19 ml/min), and the salivation rate among patients with the prevailing of SALCR was low (0.10 + 0.04 ml/min). The BC of saliva among patients with the prevailing of ACR and SACR was high (9.07 + 1.23 mmol eq/l and 9.40 + 1.71 mmol eq/l, respectively) and was reduced among patients with the prevailing of SALCR (7.63 + 0.18 mmol eq/l). The NOx level in SRPSG among patients with GERD was increased (especially in Group 3 (20.93 + 11.23 umol/l)). The direct correlation between the indicators of sialometry, the level of the BC of saliva, and the NOx level in SRPSG were established during the study.

В статье рассматриваются особенности своевременного выявления новой короновирусной инфекцией (НКИ) у пациентов хирургического профиля на уровне приемного отделения областной клинической больницы. Представленная работа является в настоящее время крайне актуальной, в виду продолжающейся в мире пандемии НКИ - Covid-19. Важное значение данному исследованию придает то, что оно направлено на как можно более раннюю диагностику Covid-19, уже на уровне нахождения в приемном отделении при поступлении в многопрофильный стационар. Подобные меры могут существенно помочь в сохранении здоровья медицинских работников и могут оказать положительное влияние на эпидемиологическую обстановку в целом. Интересной составляющей данного исследования является и то, что диагностика Covid-19 основывается лишь на тех лабораторных анализах, которые можно быстро определить в условиях приемного отделения. Объектами исследования послужило 200 пациентов, поступающих в приемное отделение БУЗ ВО ВОКБ №1 исключительно с хирургической патологией. Все больные были подразделены на 4 группы по 50 человек, всем им был поставлен сопутствующий диагноз Covid-19. В 1 группу вошли пациенты, поступающие в приемное отделение без сознания, сбор анамнеза и сбор жалоб у которых был невозможен. 2 группу составили пациенты, у которых НКИ была диагностирована непосредственно после оперативного вмешательства. В 3 группу вошли пациенты, у которых была выявлена НКИ, но объем оперативного вмешательства и объем поражения легких позволял им дальнейшее амбулаторное лечение. 4 группу составили пациенты, у которых Covid-19 выявлялся в течение 3 дней после оперативного вмешательства. У всех больных подробно собирался анамнез жизни и эпидемиологический анамнез (за исключением 1 группы), анализировались наиболее частые клинические проявления и показатели общего и биохимического анализа крови, обрабатывались данные КТ легких. Были определены основные клинические симптомы НКИ, такие как: повышенная температура тела, кашель, слабость и утомляемость. Наиболее важными лабораторными показателями стало определение уровня лейкоцитоза, с уровнем нейтрофилов и лимфоцитов, а также СОЭ, D-димера, С-реактивного белка. Представленная статья представляет большой интерес для врачей, работающих в условиях приемных отделений многопрофильных стационаров. По результатам работы планируется продолжение исследования с большей выборкой пациентов и большим количеством изучаемых параметров The article discusses the features of the timely detection of a new coronavirus infection (NCI) in surgical patients at the level of the admission department of a regional clinical hospital. The presented work is currently extremely relevant, in view of the ongoing NСI pandemic in the world - Covid-19. The importance of this study is attached to the fact that it is aimed at the earliest possible diagnosis of Covid-19, already at the level of being in the admission department upon admission to a multidisciplinary hospital. Such measures can significantly help preserve the health of medical workers and can have a positive impact on the epidemiological situation in general. An interesting component of this study is the fact that the diagnosis of Covid-19 is based only on those laboratory tests that can be quickly determined in the conditions of the admission department. The objects of the study were 200 patients admitted to the admission department of BUZ VO VOKB № 1 exclusively with surgical pathology. All patients were divided into 4 groups of 50 people, all of them were diagnosed with a concomitant Covid-19 diagnosis. Group 1 consisted of patients admitted to the emergency department unconscious, and it was impossible to collect anamnesis and collect complaints. Group 2 consisted of patients in whom NCI was diagnosed immediately after surgery. Group 3 included patients who had NCI, but the volume of surgery and the volume of lung lesions allowed them further outpatient treatment. Group 4 consisted of patients in whom Covid-19 was detected within 3 days after surgery. In all patients, a detailed life history and epidemiological history were collected (except for group 1), the most frequent clinical manifestations and indicators of general and biochemical blood tests were analyzed, and CT data of the lungs were processed. The main clinical symptoms of NCI were identified, such as: fever, cough, weakness and fatigue. The most important laboratory indicators were the determination of the level of leukocytosis, with the level of neutrophils and lymphocytes, as well as ESR, D-dimer, C-reactive protein. The presented article is of great interest to doctors working in the admission departments of multidisciplinary hospitals. Based on the results of the work, it is planned to continue the study with a larger sample of patients and a large number of studied parameters

Abstract Nitrate and nitrite ions taken from food are the sources of bioavailable nitric oxide (NO) in the nitrogen cycle. Some beneficial effects of honey on health are attributed to the ability of honey to increase NO production. The variation of nitrate and nitrite levels of honey samples collected from different Anatolia regions were clarified using capillary electrophoresis technique. The sensitivities of both anions were improved with the application of the sample stacking method. Separation buffer consisted of 30 mmol L−1 formic acid and 30 mmol L−1 sodium sulfate at a pH of 4.0. The CE technique revealed that 18 honey samples contained nitrate anion ranged between 2.53 and 31.8 mg kg−1. Nitrite amounts were found in lower amounts in the honey samples as between non-detected and 0.533 mg kg−1. The observed differences in nitrate levels between honey varieties may be a way to determine honey's origin.

BACKGROUND: Assessing the severity of endothelial dysfunction (ED) and making a prognosis after open reconstructive interventions in patients with peripheral atherosclerosis is complicated due to a limited number of conventional routine methods, including laboratory ones, available for establishing associations between biochemical markers and disease outcomes. AIM: This work is dedicated to the evaluation of nitric oxide (II) metabolites (nitrates and nitrites) in patients with complications following open bypass procedures on the lower extremity arteries using synthetic grafts in order to assess the severity of endothelial dysfunction and its negative sequalae. MATERIALS AND METHODS: The study involved 60 subjects with stage IIb–III chronic lower limb ischemia according to A. V. Pokrovsky–Fontaine classification (categories 3–5 Rutherford) due to atherosclerotic peripheral artery disease. Median age of the subjects was 65 (60–67); the majority of the patients were male (51 (85%). Median value of ankle-brachial index at baseline was 0.32 (0.19–0.42). All participants underwent open bypass grafting procedures using synthetic vascular grafts. Nitric (II) oxide (NO) metabolites level (nitrites and nitrates) was measured before the intervention and three months afterwards by spectrophotocolorimetry using an ELISA analyzer Stat Fax 3200 (Awareness Techonology, Inc., USA) and Griess reagent. The subjects were followed up for a year to determine the rate of development of complications such as restenosis, graft thrombosis, limb loss (major amputation), lethal outcomes, as well as disease progression, myocardial infarction, oncology, and stroke. RESULTS: Performance of a reconstructive procedure on lower extremity arteries was followed by a decrease in NO metabolites level from initial median 76.3 mcmol/ml (48–100.7) to 52.4 mcmol/ml (36.1–93.8) at three months after the intervention (р = 0.015). There was a positive correlation between the NO metabolites level at baseline (0 months) and follow-up visit (3 months) (r = +0.573). Complications within one year after bypass procedures were detected in 66.64% subjects. Baseline level of NO metabolites in patients who required an amputation within one year after the procedure was markedly elevated and reached 116.3 mcmol/ml (90–130.5) (p = 0.025); development of restenosis and lethal outcomes within one year were associated with initially low NO metabolites levels, 35.6 mcmol/ml (p = 0.036) and 33 mcmol/ml (30–36), accordingly (р = 0.043). CONCLUSIONS: Both markedly high and low levels of nitric oxide metabolites (nitrates and nitrites) levels are associated with development of severe complications after open reconstructive procedures in patients with peripheral atherosclerosis. Quantitative determination of the NO metabolites level in serum is a relatively easy and reliable method allowing for the determination of the severity of endothelial dysfunction and its sequalae in subjects after open bypass reconstructive procedures on lower extremity arteries.

Nitric Oxide Metabolites

In this study, we developed a fluorescence measurements in microplates for high-throughput determination of nitric oxide (NO) metabolites, which is used as a reliable and sensitive marker of NO production, in biological fluids using a pH-independent fluorescence increasing probe, DAMBO-PH. The sensitivity of this method is lower than that of the other detection methods reported in the literature. This method was demonstrated to be useful for the rapid screening of large numbers of biological and clinical samples, and should be an important tool for further clarifying the physiology, pathology and pharmacology roles of NO.

Papillary renal cell carcinoma is an uncommon malignant tumor, which rarely metastases to the bladder and/or omentum. We report the case of a 71-year-old woman with macrohematuria for two years and a large mass on the right flank. Thus, we present a brief review of the literature regarding the classification, clinical manifestations, diagnosis, immunohistochemical profile, and treatment of this neoplasm. Special attention was given to the role of immunohistochemistry, which was decisive for the determination of multiple metastases, as well as the study by imaging exams, which defined the best surgical approach.

The focus of discussion in Working Group 3 was on the Thermodynamic Properties as determined spectroscopically, including the observational techniques and the theoretical modeling of physical processes responsible for the emission spectrum. Recent advances in observational techniques and theoretical concepts make this discussion particularly timely. It is wise to remember that the determination of thermodynamic parameters is not an end in itself and that these are interesting chiefly for what they can tell us about the energetics and mass transport in prominences.

Choice of profession is a social phenomenon that every person has to face in life. Numerous studies convince us that not only the well-being of a person depends on the chosen work, but also his attitude to himself and life in general, therefore, the right and timely professional choice is very important. Research about factors of career self-determination of students of higher education institutions in Ukraine shows that self-determination is an important factor in the socialization of young person, and the factors that determine students' career choices become an actual problem of nowadays. The present study involved full-time and part-time students of Institute of Philology and Mass Communications of Open International University of Human Development "Ukraine" in order to examine the factors of career self-determination of students of higher education institutions (N=189). Diagnostic factors of career self-determination of students studying in the third and fourth year were carried out using the author's questionnaire. Processing of obtained data was carried out using the Excel 2010 program; factorial and comparative analysis were applied. Results of the study showed that initial stage of career self-determination falls down on the third and fourth studying year at the university, when an image of future career and career orientations begin to form. At the same time, the content of career self-determination in this period is contradictory and uncertain, therefore, the implementation of pedagogical support of this process among students is effective.
