Thrombopoietin is associated with a prognosis of gastric adenocarcinoma
Authors: Zhou Chang-Lin , Su Hai-Long , Dai Hong-Wei
Published: July 2020

SUMMARY OBJECTIVE Thrombopoietin (THPO) is well-known as a megakaryocyte growth and development factor (MGDF) involved in megakaryocyte proliferation and maturation. To explore the biological effects of THPO in gastric adenocarcinoma, we conducted this study. Methods: By accessing the TCGA database, the expression level of THPO was determined in tumor tissues. The association between THPO expression and clinical features, or prognostic significance was described by Cox regression analysis and Kaplan-Meier. The SiRNA method was used to decline the THPO expression; then cell viability, invasion, and migration were detected to verify the effects of the knockdown of THPO. qPCR and western blotting were implemented to examine the expression level of THPO. Results: The expression of THPO was increased in tumor tissue and cells, its high-regulation was associated with a poor prognosis in patients with gastric adenocarcinoma. Cell viability, invasion, and migration were suppressed in AGS with the down-regulation of THPO. Furthermore, on the basis of si-THPO transfection, E-cadherin was promoted while N-cadherin and Vimentin were attenuated. CONCLUSION Our results revealed that THPO may be a potent marker of gastric adenocarcinoma, providing a novel potential screening method for gastric adenocarcinoma.

Published: July 2020

SUMMARY OBJECTIVE The Revised Atlanta Classification (RAC) is increasingly used in the evaluation of patients diagnosed with acute pancreatitis (AP). In our study, we aimed to evaluate the etiology, disease severity, and mortality rates of patients diagnosed with AP in our center in the previous 6 years. METHODS Patients diagnosed with AP between 2013 and 2018 were evaluated. AP etiology, demographic data, disease severity, and mortality rates according to the RAC were evaluated. RESULTS A total of 880 patients were included in the study. Five hundred and eighteen (59%) patients were female and 362 (41%) were male. Regarding the etiology, 474 (53.9%) patients had biliary AP (BAP), 71 (8.1%) had hyperlipidemic AP (HAP), and 44 (5%) had alcoholic AP (AAP). According to the RAC, 561 (63.7%) patients were considered to be in the mild AP group (MAP), 268 (30.5%) in the moderately severe AP (MSAP), and 51 (5.8%) in the severe AP (SAP). The mortality rate was 4.8% in the MSAP group and 49% in the SAP group. Mortality was 2.3 times in patients over 65 years old and 3.7 times higher in patients with ischemic heart disease. CONCLUSIONS In our country, BAP is still the main etiology of acute pancreatitis. Over the years, we have seen a decrease in BAP and idiopathic AP cases, while there was an increase in HAP cases due to factors such as lifestyle changes and fatty nutrition. We found that mortality was associated with disease severity, advanced age (> 65 y), hypertension, and ischemic heart disease regardless of the etiology.
Residual lesions in patients who underwent microsurgical clipping of cerebral aneurysms

Published: July 2020

SUMMARY Microsurgical clipping is currently the main method of treating cerebral aneurysms, even with the improvement of endovascular therapy techniques in recent years. Treatment aims at complete occlusion of the lesion, which is not always feasible. Although appearing superior to endovascular treatment, microsurgical clipping may present varying percentages of incomplete occlusion. Such incidence may be reduced with the use of intraoperative vascular study. Some classifications were elaborated in an attempt to standardize the characteristics of residual lesions, but the classification criteria and terminology used in the studies remain vague and poorly documented, and there is no consensus for a uniform classification. Thus, there is also no agrément on which residual aneurysms should be treated. The aim of this study is to review the literature on residual lesions after microsurgery to treat cerebral aneurysms and how to proceed with them.
COVID-19 AS A GLOBAL DISASTER: Challenges to risk governance and social vulnerability in Brazil
Authors: Freitas Carlos Machado de , Silva Isadora Vida de Mefano e , Cidade Natália da Cunha
Published: July 2020

Abstract On March 11 2020, the Director of the World Health Organization characterized the Public Health Emergency by COVID-19 as a pandemic (PAHO, 2020). In this article we understand this pandemic as a Global Disaster that can evolve into a Complex Emergency presenting risks for a Humanitarian Crisis in many countries, including Brazil. In this context we face two challenges: the governance of risks and coping and reducing vulnerabilities. In Brazil political, social and economic threats overlap with the dangers caused by the Sars-Cov-2 virus. These threats undermine the capacity for risk governance and widen and intensify social inequalities, making Brazil the new epicenter of the global disaster by COVID-19.
Fighting the invisible anaconda amidst a war of conquest: notes of a genocide
Authors: Milanez Felipe
Published: July 2020

Abstract The conquest of indigenous territories and epidemic diseases have gone hand in hand throughout the history of Brazil. The current new coronavirus pandemic that is devastating indigenous communities follows this violent strategy of conquest. My argument is that structural racism that has led to the death of more than 200 indigenous people in the first months of the pandemic should be seen not as irresponsible acts of omission, but as acts of genocide.

RESUMO: Objetivos: Descrever o perfil dos atendimentos por agressões em unidades de urgência e emergência com base nos dados do Inquérito de Violências e Acidentes em Serviços Sentinela de Urgência e Emergência (VIVA Inquérito) 2011, 2014 e 2017 e comparar a evolução de seis indicadores ao longo de quatro (2011 a 2014) e sete anos (2011 a 2017). Métodos: Estudo transversal, com dados das três últimas edições do VIVA Inquérito realizadas no Distrito Federal e em 19 capitais do Brasil. Foram selecionados os tipos de ocorrência: agressão/maus-tratos e intervenção por agente público. Calcularam-se as frequências ponderadas das características das pessoas atendidas, das agressões, das lesões e da evolução dos casos, segundo o sexo. As diferenças entre as proporções foram comparadas pelo teste χ2. Também foram selecionados seis indicadores, e avaliou-se sua evolução ao longo dos anos por meio da variação percentual e do intervalo de confiança a 95%. Resultados: Em grande parte dos atendimentos por agressão, os indivíduos eram negros, jovens e adultos, em ambos os sexos. A principal natureza das agressões foi física, alcançando mais de 85% em todos os inquéritos, seguida da negligência. Na comparação entre 2011 e 2017, as agressões de natureza negligência tiveram aumento significativo em ambos os sexos e em crianças e idosos; já as agressões de natureza sexual tiveram aumento significativo apenas em crianças. Conclusões: O VIVA Inquérito é uma importante ferramenta para o Sistema de Vigilância de Violências e Acidentes do Brasil, proporcionando evidências para a tomada de decisões em Saúde Coletiva e para o enfrentamento e a prevenção das violências.

ABSTRACT Objective: To describe the case of a child who presented hemophagocytic lymphohistiocytosis (HLH) associated with acute monocytic leukemia after chemotherapy, with hemophagocytosis caused by leukemic cells. Case description: In a university hospital in Southern Brazil, a 3-year-old female was diagnosed with acute monocytic leukemia with normal karyotype. The chemotherapy regimen was initiated, and she achieved complete remission six months later, relapsing after four months with a complex karyotype involving chromosomes 8p and 16q. The bone marrow showed vacuolated blasts with a monocytic aspect and evidence of hemophagocytosis. The child presented progressive clinical deterioration and died two months after the relapse. Comments: HLH is a rare and aggressive inflammatory condition characterized by cytopenias, hepatosplenomegaly, fever, and hemophagocytosis in the bone marrow, lymph nodes, spleen, and liver. Although rare, malignancy-associated HLH (M-HLH) is fatal. The patient in this case report met five out of the eight established criteria for HLH. The evolution of the patient’s karyotype, regardless of the diagnostic profile, seemed secondary to the treatment for acute monocytic leukemia. In this case, the cytogenetic instability might have influenced the abnormal behavior of leukemic cells. This is a rare case of HLH in a child with acute monocytic leukemia.

Published: July 2020

RESUMEN En la última década, la innovación no tecnológica ha llamado mucho el interés de los investigadores. Este tipo de innovación incluye la organizacional y comercial. El presente estudio se enfoca en dos objetivos principales: identificar la relación entre las fuentes externas de conocimiento y la innovación en producto, organizacional y comercial; y analizar cómo la innovación en producto y organizacional median la relación entre las fuentes externas de conocimiento y la innovación comercial. Actualmente, los estudios sobre este tipo de innovación no presentan su real impacto e importancia para las empresas de manufactura, por lo que es importante prestarle atención. Usando los datos de 557 empresas peruanas de manufactura que presentan una menor intensidad tecnológica, se aplicó un modelo de ecuaciones estructurales. Los resultados mostraron que las fuentes externas de conocimiento están relacionadas con la innovación en producto y organizacional. Por ello, los gerentes deben impulsar las innovaciones en producto que favorezcan el desarrollo de innovaciones comerciales en la empresa.

RESUMO Este estudo se propõe a analisar como percepções temporais influenciam vivências de prazer e sofrimento no trabalho de prostitutas, em Belo Horizonte (MG). Foi realizado um estudo de caso, de natureza qualitativa descritiva. A coleta de dados deu-se por meio de entrevistas com roteiro semiestruturado. Foram abordadas 15 profissionais dos chamados “hotéis de batalha”, e os dados coletados foram tratados por meio de análise de conteúdo. As prostitutas entrevistadas associam o tempo a um recurso, e isso se vincula a vivências de prazer e sofrimento, no sentido de que a administração adequada do tempo gera, para elas, o dinheiro, que é a principal fonte de prazer do seu trabalho. Contudo, esse tempo de trabalho é também fonte de vivências de sofrimento, uma vez que as prostitutas naturalizam ou aceitam incômodos em relação ao trabalho e às consequências que ele acarreta.

Volumetric behaviour of clays under freeze–thaw cycles in a mesoscopically uniform element
Authors: Nishimura Satoshi , Okajima Shota , Joshi Bhakta Raj , Higo Yosuke , Tokoro Tetsuya
Published: July 2020

The volume change behaviour of fine-grained soils under repeated freeze–thaw cycles was investigated in context of artificial ground freezing, in which relatively quick freezing is achieved under confinement. Laboratory cyclic freeze–thaw tests with large freezing rates were performed on two clays in two different laboratory set-ups, either with isotropic pressure or with one-dimensional configuration. After freeze–thaw cycles, soils appear to reach residual states unique to each stress level, and the freeze–thaw residual line (FTRL) is defined to represent them. The current soil state's distance to the FTRL, defined as the freeze–thaw state parameter, is well correlated to subsequent volume changes. The one-dimensional freezing set-up provides a correlation more representative of the net effect of freeze–thaw, as all-around freezing under isotropic pressure subjects the specimen to unnatural shear straining. The different nature of freeze–thaw-induced volume changes was observed for high-plasticity Kasaoka clay and low-plasticity kaolin, as characterised by different configurations of the FTRL to the normal compression line. X-ray computed tomography confirmed largely uniform deformation in most of the adopted test conditions, while lower stress and slower freezing led to partial vertical cracking. This type of non-uniformity is shown not to be a main cause of the observed overall freeze–thaw-induced volume changes.

Published: July 2020

The use of learning management systems is becoming frequent as a form of learning. This is because it allows greater flexibility of time and space if we compare to face-to-face learning. Thus, this work aims to present how the field of ​​Educational Data Mining and Learning Analytics are contributing to the extraction of knowledge from the self-regulation of time management in e-learning environments. For this, we considered the concept of time management by Pintrich (2000) and carried out a systematic review of the literature. With that, it was possible to notice that most of the analyzed works do not study only time management. We also realized that the data, which represents time management, are aggregated data, that is, the phenomenon is not studied over time. With these results, you can see an overview of how Learning Analytics and Educational Data Mining are supporting the extraction of knowledge about self-regulation of time management in online environments.
Dimensiones del Ecosistema Digital Universitario: Validación del Instrumento «University Digital Ecosystem» (UN-DIGECO)

Published: July 2020

The purpose of the study was to design and validate the UN-DIGECO (University Digital Ecosystem) instrument, aimed at learning about the use that undergraduates make of social media and/or digital applications. The content and comprehension validation was carried out in three phases: construction, refining and psychometric validation, based on confirmatory factor analysis, supported by the initial theoretical construct. The items, designed by experts, are in line with indicators assigned to six theoretically defined dimensions: Learning, Social Interaction, Content Creation, Online Consumption, Leisure, and Recreational. Own indicators were integrated together with others adapted from similar published instruments. The preliminary version of the questionnaire was tested by a group of 25 students, some items were refined and redefined to facilitate their understanding. The pilot version included 44 items and involved 484 students from Spanish and Colombian universities. The authors analysed the latent structure of the items by applying exploratory factor analysis and, after examining the composition of the factor structure of the indicators, excluded the non-relevant ones. The results confirmed the existence of these six dimensions, which include 37 items, with a Cronbach's alpha greater than 0.8. The instrument and its components show appropriate psychometric properties of validity and reliability, being applicable to other contexts. The originality of the designed questionnaire lies in the structuring of the information, establishing and integrating six dimensions related to the use university students make of SM.

Published: July 2020

Obesity is identified as a global epidemic that triggers consequences such as increased morbidities, increased risk of developing metabolic, cardiovascular, liver diseases, cancer, diabetes, among others. Knowledge about nutrition and healthy eating in children and adolescents is one of the alternatives that stand out for its prevention. Thus, this paper presents the assessment of learning resulting from the application of the Nutrikids game. This game was developed to increase nutritional knowledge in children and adolescents. To this end, a quasi-experimental study randomized by group was carried out with 105 students aged 9 to 12 years old from two Brazilian public schools, which were divided into the Lecture Group that received information through lectures (n = 51) and the Game Group who received the same information through the Nutrikids game (n = 54) who received intervention for a month, often once a week for thirty minutes. To assess nutritional knowledge, both groups underwent a pre-test before the start of the intervention and a post-test at the end. It was observed that both groups increased their nutritional knowledge and that the Game Group had a larger effect on learning and better evaluation regardless of gender. Thus, the use of the Nutrikids game proved to be more effective for teaching nutritional knowledge when compared to traditional expository classes.

Introduction. Urethral transposition remains the most popular operation for postcoital cystitis, however, traumatism and complications, especially such as pudendal neuropathies, dyspareunia and anorgasmia, make us continue to search for effective, but safer techniques.

The study objective is to evaluate the efficacy and safety of the proposed treatment of postcoital cystitis, including removal of urethrogymenal adhesions and subsequent paraurethral filler implantation, in comparison with isolated hymenoplasty.

Materials and methods. Since 2013, 75 patients with postcoital cystitis have been treated. Patients were divided into two groups: main group – hymenoplasty (removal of urethral adhesions) with paraurethral filler implantation (n = 45), control group – hymenoplasty (n = 30). The gel was injected paraurethrically, fan-shaped, in the volume of 1–2 ml, from a point on the 6-hour conditional dial, creating a gel cushion and thus raising the meautus and distal urethra. To assess the quality of treatment, profile questionnaires were used.

Results. In the main group of patient, the quality of life improved in 35 (78 %); in 5 patients, due to the process of biodegradation of the gel during 1 year, the cystitis recidivated, which required the filler reimplantation. In 5 patients, the operation was not effective. In the control group the efficiency of isolated hymenoplasty was noted in 3 (10 %) patients, relapse of cystitis occurred in 27 (90 %) patients, which later required the implantation of a filler. No complications were observed.

Conclusions. The suggested combined technique allows to improve the results of treatment of patients with postcoital cystitis. The operation does not carry the risk of damage to the sprigs of the genital nerve, can serve as an alternative to traditional urethral transposition. The main disadvantage is the natural biodegradation of the gel, which may create the need for its reintroduction.

The study objective is to evaluate the effectiveness and safety of the 6-arm mesh OPUR implant in treatment of anterior apical prolapse. Materials and methods. Three hundred patients with anterior apical prolapse (grade III–IV cystocele, grade II–IV hysteroptosis) underwent surgery. Prolapse repair was performed using the 6-arm mesh OPUR implant.

Results. In 290 patients, the intended result was achieved (full prolapse elimination or stage I prolapse per the POP-Q (Pelvic Organ Prolapse Quantification System)). However, in 6 cases recurrences of hysteroptosis, in 4 cases recurrences of cystocele were diagnosed. The following postoperative complications were observed: hematoma of the anterior vaginal wall with spontaneous resorption in 12 patients; acute urinary retention resolved in 3–7 days after the surgery in 5.8 % cases; vaginal mucosa erosion in 4 cases (in 2 cases, fragment resection was necessary); intraoperative injury of the bladder in 3 patients (in 2 cases, prolapse repair after defect suturing was finished with transvaginal contralateral sacrospinous hysteropexy supplemented by anterior colporrhaphy; in 1 case, bladder defect was sutured prior to implantation).

 Conclusion. Transvaginal repair of anterior apical prolapse of the pelvic organs in women using the 6-arm implant is effective and relatively safe. Satisfactory anatomical results persisting for a long time (4–5 years) after implantation were achieved.

The objective is to present the clinical case of pelvic floor reconstruction after total exenteration.

Clinical case. The formation of the combined fistula after surgical treatment and combined radiation therapy for uterine body cancer is presented in female patient (57 years old). The rectum and bladder were removed, the perineal tissue was excised and a vulvectomy was performed. The rectus abdominis muscle was mobilized with epigastric artery and moved to the perineum. The wound was healed by primary tension. The patient lives a full life, adapted, and does not require analgesic therapy.

Conclusion. The treatment and diagnosis tactics for regional combined fistulas are not standardized, and surgical treatment is the method of choice, especially in cases where the patient has already had radiation therapy for malignancy and relapse.
Assessment of Antibacterial Activity of Five Endodontic Sealing Materials Against Enterococcus Faecalis
Authors: Saeed Dara
Published: July 2020

Objective: Residual and recurrence infection can be prevented by a root canal sealer that possesses good antibacterial activity, which contributes to the success of endodontic therapy. This in-vitro study conducted to evaluate the antibacterial activity of five endodontic sealers (MTA fillapex, HS Mxima MTA, Endosequence BC sealer, BioRoot RCS, and AH plus) against Enterococcus faecalis using agar diffusion test.          

Methods: Freshly mixed sealers were placed into prepared wells on agar plates. The diameter of the inhibition zone was measured after incubation for 24 hours. The data were analyzed statistically by ANOVA and LSD at a 0.05 significance.

Results: All tested samples had an antimicrobial effect against Enterococcus faecalis after 24 hours. MTA fillapex had the greatest antimicrobial effect with an inhibition diameter of 12.77mm, followed by Endosequence BC. Finally, the weakest antimicrobial effect was related to the BioRoot RCS sealer with a mean zone of inhibition of 10.26mm.

Conclusions: The root canal sealers showed different antimicrobial activity. However, MTA fillapex was the most effective sealer against the organism tested.

Authors: Mouafaq Hani , Kadir Shakhawan
Published: July 2020

Objective: Failure of the glass posts is a major and the main concern of practical dentistry. This study conducted to evaluate the mode of failure among prefabricated bundle fiber posts, prefabricated taper fiber posts, and short fiber-reinforced composite as a post and luting material using a stereomicroscope.       

Methods: Thirty mandibular premolars were divided into three groups (n=10). Group 1: prefabricated taper fiber post cemented with a resin core, group 2: prefabricated bundle fiber post cemented with a resin core and group 3: short fiber-reinforced composite used instead of post and cement. Each root specimen cut into three slices of 2 mm thickness from the cervical, middle, and apical parts of the posts. Push-out tests were performed using a universal testing machine at three sites in each root at a crosshead speed of 0.5 mm/min. Then, the specimens evaluated under stereomicroscope 40X to classify the failure mode.

Results: Sixty two specimens failed adhesively between dentin and cement in all groups, adhesive failure between the post and cement was in the second group, prefabricated taper fiber post (GC fiber post) followed by prefabricated bundle fiber posts (Rebilda GT) (17 sections), and the mixed failure was second for prefabricated bundle fiber posts (Rebilda GT) and third for prefabricated taper fiber post (GC fiber post) (11sections). 

Conclusions: Adhesive failure between cement and dentin is dominant in all post systems in three sites of the roots (cervical, middle, and apical). The second most frequent failure is adhesive between post and cement in all regions in post systems.

Published: July 2020

Objective: The study aimed to evaluate the effects of subgingival irrigation of curcumin as an adjunct to scaling and root planing in the treatment of chronic periodontitis.       

Methods: 60 patients aged 30-50 years with chronic periodontitis recruited; 20 patients received subgingival irrigation of 1% of curcumin solution, 20 patients received subgingival irrigation of 0.12% of chlorhexidine solution, and 20 patients received scaling and root planing only (SRP). Pocket irrigation was conducted at baseline, 3, and 7 days after scaling and root planing. Clinical parameters and blood samples were collected at baseline before therapy and after two months of treatment to estimate the levels of total protein (TP), C-reactive protein (CRP), albumin, and alkaline phosphatase (ALP) enzyme.

Results: Significant reduction of clinical and biochemical parameters after two months of treatment in the curcumin group (P<0.05). Nearly the same pattern for the chlorhexidine group (P<0.05), with non-significant differences with a baseline for albumin (P>0.05). Reduction of clinical parameters (P<0.05) and increase of CRP, ALP, and TP levels had been seen after scaling and root planing in the SRP group. No significant differences between the three main groups in relation to clinical parameters (P>0.05), with the exception of the gingival index and biochemical parameters (P<0.05).

Conclusions: Curcumin can be effectively used as an adjunct to scaling and root planing as chlorhexidine in chronic periodontitis due to the reduction of clinical parameters and inflammatory chemical markers; CRP, TP, and ALP enzyme.

Authors: Younus Sanarya , Al-Kaisy Neda
Published: July 2020

Objective: This study aimed to compare the effects of three commercially available denture cleansing solutions on the dimensional stability of heat cure acrylic denture bases.   

Methods: Twenty four maxillary acrylic denture base samples were constructed and divided into four groups. Group 1. water as control, group 2. 1% Sodium hypochlorite, group 3. 2% Chlorhexidine, and Group 4. Kin tablet solution. Linear dimensional measurements were conducted along with five-time intervals: 0 times: before immersion, three days, ten days, one month, and two months after immersion. After each time interval, the specimens were photographed in a standardized manner, and the images were evaluated by Image J software. The dimensions between six projection points on the intaglio surface of denture bases were recorded and compared. Data were submitted to statistical analysis (Two-way ANOVA, Tukey test, p < 0.05).

Results: All specimens in three disinfectant solutions and water exhibited a small amount of linear expansion at all time intervals. The expansion was significant compared to the 0-time immersion. On the tenth day of immersion, the dimensional change becomes stable and constant until the end of the two months. Among the three disinfectants, 1% of Sodium hypochlorite registered the least expansion in some measured lines at two-time intervals followed by 2% Chlorhexidine.

Conclusions: Cleanser solutions induced dimensional changes on acrylic denture bases similar to the effect of water in all examined measurements. The long time cleanser's immersion had the same effect on the dimension as the short time effect.

Authors: Rahman Asma , Amin Rebin , Saleh Muhammed
Published: July 2020

Objective: Dental anomalies are abnormal morphological development of dentition during various periods of tooth development and have an important role in the development of various kinds of malocclusions. If dental anomalies not diagnosed, they can make dental and orthodontic treatment more difficult. So, orthodontists and the general dental practitioner must investigate patients carefully. The objective of the current study was to determine the prevalence and distribution of dental anomalies in a sample of orthodontic patients in Erbil city using orthopantomogram.`   

Methods: Four hundred fifty-eight orthopantomograms of orthodontic patients with age of 16-40 years evaluated to determine the prevalence and distribution of the hypodontia, impaction, microdontia, and supernumerary tooth.

Results: 15.06% orthodontic patients: 21 males and 48 females had at least one dental anomaly. Impaction and hypodontia were the most common dental anomalies with no significant difference between genders. Maxillary canines were more commonly impacted tooth, whereas maxillary lateral incisors were the most common tooth agenesis among genders.

Conclusions: Impaction was the most prevalent dental anomaly, and maxillary canines were the most involved teeth and are in agreement with many studies among various populations. The most frequently missing teeth were the maxillary lateral incisors. However, mandibular 2nd premolar was the most common hypodontia in some studies.

Published: July 2020

Objective: Aberrant BubR1 and Telomerase expressions are considered as important markers in tumor progression and clinical outcome. This study purposed to describe, compare, and correlate the immunohistochemical expression of BubR1 and Telomerase in oral squamous cell carcinoma (OSCC).

Methods: Immunohistochemical staining was performed for 28 OSCC samples. The samples graded according to Bryne’s grading system. The reaction positivity, intracellular localization, and intensity were recorded. The expression distribution and mean-ranks of these markers were related to OSCC grades by Fisher’s exact and Kruskal Wallis tests. Finally, the correlation between them was achieved by Spearman’s rho test.

Results: BubR1 was detected in 89.3% of OSCCs, equally within scores 2 and 3 (35.7%), presented with 50% faint intensity, and 64.3% cytoplasmic localization. Grade III had a significantly higher mean-rank of BubR1 scoring. Whereas Telomerase observed in 75% of OSCCs, mainly found at scores 2 and 3 (60.7%), and 42.9% was within the cytoplasm. Half of OSCCs had faint intensity. No significant differences reported in the mean-rank and stain intensity among the grades. There was no significant correlation between BubR1 and Telomerase expression.

Conclusions: OSCCs had high cytoplasmic BubR1 and telomerase expression that cannot ensure proper function. Mean-rank of BubR1 expression related to OSCC grading and being more in high grade. It determines the loss of differentiation and aggressiveness of OSCC. While the mean-rank of Telomerase did not relate to histopathological grading and considered an early event in carcinogenesis, it can use for the diagnostic approach of oral carcinogenesis. These markers have an independent role in cancer progression.
CREDIT RISKS MITIGATION AND BANKING COLLATERAL VALUATION IN UKRAINE
Authors: Yakubovsky V.
Published: July 2020

Contemporary international requirements and mechanisms which are oriented to credit risks abatement and assurance of financial sector functioning are reviewed with particulars of their implementation in national banking sector. As is demonstrated general reasons for the new generation of regulatory measures of crisis resilience in financial sector are grown up from the last global economy crisis which demonstrated vulnerability of the main credit institutions and their failure to absorb considerable financial market fluctuations. To improve financial systems stability is the main goal of measures and instruments proposed by the international Basel Committee on Banking Supervision as well as Directives and Regulations of the European Union, which should be implemented at the national level. One of the underlining aspect in this new international regulatory documents is recognition of the assets valuation key role in the whole methodology of risks mitigation. Main approaches to consider time effect on assets valuation results are analyzed in this context. Based on these last international regulatory documents in this direction special Resolution No. 351of the National Bank of Ukraine has been issued for banks credit risks assessment. Much less attention in this Resolution is given to assets valuation which is linked to some extent with outdated national valuation standards. This situation requires active measures to be provided for updating basic national documents in this area as is underlined.
THE POLITICAL ECONOMY OF GLOBAL VALUE CHAINS RESTRUCTURING
Authors: Rogach O.
Published: July 2020

The article analyzes the international production of multinational enterprises (MNEs). It presents some theoretical approaches to the analysis of international production, such as fragmentation theory, global value chains (GVCs) theory. The article argues that at the present stage of the world economy internationalization, there are two trends in the localization of MNEs global chains. The first trend indicates a slowdown of GVCs growth in the last seven years. The second trend characterizes the restructuring of GVCs. It indicates the backward movement of certain international production fragments to the MNEs home countries. Among the major factors that have slowed the growth of international MNEs production, the article analyzes the political instability and low economic dynamics of some FDI exporting countries. Changes in the location of global value chains are driven by technological, economic and geopolitical factors. Fourth industrial revolution, the robotization of production and new technologies for shale oil and gas in the US are changing the traditional determinants for GVCs localization. They have caused the relocation of many businesses from countries with the cheap labour to MNEs home countries. The article also highlights that the important factors of GVCs restructuring are the fiscal mechanisms implemented by the US administration, including tax reform. But the short-term and long-term effects of such measures differ significantly. Finally, the third important factor in the dynamics and restructuring of multinational enterprise network production is the geopolitical risk and political uncertainty. The trade war between the US and China has had a particularly significant impact on the current global value chains rebuilding.
