          Prognostic Value of Soluble ST2 During Hospitalization for ST-Segment Elevation Myocardial Infarction

          Olga Barbarash,Olga Gruzdeva,Evgenya Uchasova,Yulia Dyleva,Ekaterina Belik,Olga Akbasheva,Victoria Karetnikova,Aleksandr Shilov 대한진단검사의학회 2016 Annals of Laboratory Medicine Vol.36 No.4

          Background: Studying the role of soluble ST2 (sST2) during hospitalization for myocardial infarction (MI) can be helpful for predicting the course of the hospitalization and development of complications. Methods: We included 88 patients with MI (median age, 58 yr). Depending on the course of the hospitalization, the patients were divided into two groups: the favorable (n=58) and unfavorable (n=30) outcome groups. On days 1 and 12 after MI, serum sST2 and N-terminal pro-brain natriuretic peptide (NT-proBNP) were measured by ELISA. Results: On day 1, the concentrations of sST2 and NT-proBNP increased 2.4- and 4.5-fold, compared with the controls. Measurements on day 12 showed a significant decrease in the sST2 level (P=0.001), whereas the NT-proBNP level did not change. On day 1, the sST2 level in the unfavorable outcome group was 2-fold higher than that in the favorable outcome group and 3.7-fold higher than in the controls. On day 12, the marker level decreased in both groups. On day 1, the NT-proBNP level in the unfavorable outcome group was 6.8-fold higher than in the controls and 1.8-fold higher than in the favorable outcome group. On day 12, the level of NT-proBNP remained elevated in both groups. Determining the levels of both sST2 and NT-proBNP increases their diagnostic significance (odds ratio [OR], 1.92; 95% confidence interval [CI], 1.7-3.2; areas under curve [AUC] 0.89; P=0.004). Conclusions: The level of sST2 is a more sensitive indicator during MI hospitalization than NT-proBNP.

        • Frequency of EGFR Mutations in Non-small Cell Lung Cancer Patients: Screening Data from West Siberia

          Gervas, Polina,Ivanova, Anna,Vasiliev, Nikolay,Ananina, Olga,Zharkova, Olga,Rogovieva, Olga,Verzhbitskaya, Natalia,Didichuk, Ivan,Cheremisina, Olga,Popova, Natalia,Goldberg, Victor,Cherdyntsev, Evgeny Asian Pacific Organization for Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.2

          Background: Incorporation of molecular analysis of the epidermal growth factor receptor (EGFR) gene into routine clinical practice has shown great promise to provide personalized therapy of the non-small cell lung cancer (NSCLC) in the developed world. However, the genetic testing of EGFR mutations has not yet become routine clinical practice in territories remote from the central regions of Russia. Therefore, we aimed to study the frequency of major types of activating mutations of the EGFR gene in NSCLC patients residing in West Siberia. Materials and Methods: We examined EGFR mutations in exons 19 and 21 in 147 NSCLC patients (excluding squamous cell lung carcinomas) by real time polymerase chain reaction. Results: EGFR mutations were detected in 28 of the 147 (19%) patients. There were 19 (13%) cases with mutations in exon 19 and 9 cases (6%) in exon 21. Mutations were more frequently observed in women (42%, p=0.000) than in men (1%). A significantly higher incidence of EGFR mutations was observed in bronchioloalveolar carcinomas (28%, p=0.019) and in adenocarcinomas (21%, p=0.024) than in large cell carcinomas, mixed adenocarcinomas, and NOS (4%). The EGFR mutation rate was much higher in never-smokers than in smokers: 38% vs. 3% (p=0.000). The frequency of EGFR mutations in the Kemerovo and Tomsk regions was 19%. Conclusions: The incorporation of molecular analysis of the EGFR gene into routine clinical practice will allow clinicians to provide personalised therapy, resulting in a significant increase in survival rates and improvement in life quality of advanced NSCLC patients.

          Morphometric Characterization of Honey Bee, Apis mellifera Linnaeus, Inbred Lines in Korea

          Olga Frunze,Yong Soo Сhoi,Dong Won Kim,Bo Sun Park,Hee Geun Park,Eun Jin Kang 한국응용곤충학회 2020 한국응용곤충학회지 Vol.59 No.4

          이탈리안벌인 A, C, F계통과 코카시안벌인 D, V계통을 2005년부터 2007년까지 국내에서 수집하였다. 수집한 계통은 육종을 위해 격리 된 섬에서 근친교배를 통해 순계로 분리하였다. 이 연구는 꿀, 로열젤리 다수확계통 선발에 있어 개체군 선발과 육종 효율을 높이기 위해 수행되 었다. 23 개의 형태학적 특성을 평가하고 두 아종의 기존 데이터와 비교한 결과, 이탈리안벌 순계계통은 코카시안벌 순계 계통과 달리8개의 특성이 기존의 이탈리안벌과 유사해 더 많은 특성이 보존되고 있음을 알 수 있었다. 또한 국내에서 유지되고 있는 순계들은 타 지역의 동일 계통과 차 이를 보여 분리된 순계의 형태적인 특징이 확인되었다. The A, C, F colonies of Apis mellifera ligustica Spin. and D, V colony of Apis mellifera caucasia Gorb. bees were collected from 2005-2007. Consequently, inbred lines were derived from the bees of original colonies by matting in the isolated island with due regard for pure breeding. This project helps in the selection of colonies with higher production capacity, aiming to improve honey and royal jelly production and breeding programs. Twenty-three standard morphological traits of honeybee were evaluated, and samples were compared with the data of the two original subspecies. The result suggested that 8 traits partly preserved in bees of inbred lines, and the bees from A. m. ligustica preserved more traits than bees from A. m. caucasia. Among the studied inbred lines, the F line is distinguished by an increase in leg parameters, considered as a favorable phenotypic trait of inbred lines. Importantly, bred of beelines in the same area can be classified as remote and isolated areas. Therefore, we observed differences of inbred lines with the origin subspecies in description acquired with morphometric characteristics as a result of adaptation, breeding, purebred individual lines used as an important resource for breeding novel cross-breeding colonies.

          The Effect of Perceived Value of Distance Selling on Psychological Distance and Customer Loyalty

          Olga Durkalo,박영근,박재진 한국무역연구원 2021 貿易 硏究 Vol.17 No.4

          Purpose This study is to examine whether the perceived value of customers who purchase through a distance selling method such as an Internet shopping mall affects the psychological distance and how this leads to customer loyalty. Also, by analyzing the mediating effect of psychological distance, it was verified whether psychological distance plays a mediating role between the perceived value of distance selling and customer loyalty. Design/Methodology/Approach Data collection was conducted for foreigners residing in Korea. We asked 250 people in various occupations in Korea to respond voluntarily by sending out a questionnaire made with Google Forms via email and KakaoTalk. Emails sent to respondents and KakaoTalk contain links to online questionnaires. Finally, 203 survey respondents were used for the analysis. Findings First, the perceived value of distance selling was found to have a significant effect on psychological distance. It was found that functional value and financial value had a significant negative (-) effect on psychological distance, and emotional value had a significant positive (+) effect. However, social value did not affect psychological distance. This means that the better the quality and service, and the more money you save, the less time, space, and social distance you feel. On the other hand, it can be seen that the stronger the desire or emotion to purchase, the more psychological distance is felt. Second, it was found that the psychological distance feeling for long-distance purchase had a negative effect on customer loyalty. This means that as the distance purchasing customers feel a sense of temporal, spatial, and social distance, their repurchase or recommendation intention decreases. Third, as a result of analyzing the mediating effect of psychological distance, it was confirmed that the perceived value of distance selling leads to customer loyalty through psychological distance. This means that distance sellers need marketing efforts to reduce the psychological distance that customers feel in order to increase customer loyalty. Research Implications It is difficult for customers who make distance purchases through online shopping malls to judge perceived values such as functional values of products. Therefore, reducing the psychological distance of consumers by providing detailed information on the producer, production location, and production process to the distance selling site will increase the repurchase intention. Also, distance sellers need marketing efforts to build customer trust in order to increase perceived value and reduce customers’ psychological distance.

          Inhibition in the amygdala anxiety circuitry

          Olga Babaev,Carolina Piletti Chatain,Dilja Krueger-Burg 생화학분자생물학회 2018 Experimental and molecular medicine Vol.50 No.-

          Inhibitory neurotransmission plays a key role in anxiety disorders, as evidenced by the anxiolytic effect of the benzodiazepine class of γ-aminobutyric acid (GABA) receptor agonists and the recent discovery of anxiety-associated variants in the molecular components of inhibitory synapses. Accordingly, substantial interest has focused on understanding how inhibitory neurons and synapses contribute to the circuitry underlying adaptive and pathological anxiety behaviors. A key element of the anxiety circuitry is the amygdala, which integrates information from cortical and thalamic sensory inputs to generate fear and anxiety-related behavioral outputs. Information processing within the amygdala is heavily dependent on inhibitory control, although the specific mechanisms by which amygdala GABAergic neurons and synapses regulate anxiety-related behaviors are only beginning to be uncovered. Here, we summarize the current state of knowledge and highlight open questions regarding the role of inhibition in the amygdala anxiety circuitry. We discuss the inhibitory neuron subtypes that contribute to the processing of anxiety information in the basolateral and central amygdala, as well as the molecular determinants, such as GABA receptors and synapse organizer proteins, that shape inhibitory synaptic transmission within the anxiety circuitry. Finally, we conclude with an overview of current and future approaches for converting this knowledge into successful treatment strategies for anxiety disorders.
