Mixed Neuroendocrine Carcinoma and Hepatocellular Carcinoma: A Case Report and Literature Review
Authors: Lan Jianwei , Guo Deliang , Qin Xian , Chen Baiyang , Liu Quanyan 
Published: July 2021

Background: Neuroendocrine tumors are heterogeneous malignancies that originate from the neuroendocrine system. Previous studies show that this cancer type mainly localizes in the gastrointestinal tract and often metastasizes to the liver. Primary liver neuroendocrine tumors are very rare and primary hepatic neuroendocrine tumors (PHNET) with concurrent hepatocellular carcinoma (HCC) are extremely rare. To the best of our knowledge, only few PHNET cases have been identified, making their diagnosis difficult. Here, we report the biggest ever reported and “deceiving” lesion of a mixed neuroendocrine-non-neuroendocrine neoplasm in the liver, aiming to raise awareness and improve treatment of the disease.Case Presentation: Here, we report a preoperative misdiagnosed case that presented with hepatocellular carcinoma clinical features and no extrahepatic tumors. Postoperative pathology confirmed that it was a mixed neuroendocrine-non-neuroendocrine neoplasm. The patient was then referred for etoposide and cisplatin-based chemotherapy. No disease recurrence was observed at the 6-month follow-up.Conclusion: We report a very rare and easily misdiagnosed case and we speculate that there were “undifferentiated cells” undergoing neuroendocrine and hepatocellular carcinoma differentiation, during which some hepatocellular carcinoma cells express neuroendocrine features. We recommend proper surgery and postoperative platinum-based chemotherapy in the management of this disease.

Published: July 2021

Приведены доказательства того, что изобретение, публично продемонстрированное русским ученым-физиком А.С. Поповым 7 мая 1895 г., положило начало беспроводной связи. Рассмотрены следующие вопросы: что произошло в эту знаменательную дату; на чьих работах базировался Попов, создавая схему беспроводной связи. Показаны сущность и новизна технического решения. Опровергается ошибочное мнение о том, что 25 апреля (7 мая) 1895 г. А.С. Попов официально представил грозоотметчик. Для сравнительной оценки вклада Попова и его предшественников в изобретение радио использован синергетический подход; кроме того, возникновение и развитие радиосвязи представлены в виде последовательности этапов инновационного процесса. В условиях, когда национальные интересы и общий скепсис в отношении того, что у радио есть изо -бретатель, привели к появлению понятий «коллективный разум», «пионеры радиосвязи», и их список с годами растет (в наши дни во многих странах есть «свой Попов»), популяризация научно обоснованных сведений о Попове как о первооткрывателе радио - Колумбе радиотехники приобретает особую важность.
The article presents the evidence that the invention, publicly demonstrated by the Russian physicist A.S. Popov on May 7 (new style), 1895, marked the beginning of wireless communication. The following questions are discussed. What happened on that date? On whose works Popov was based, creating a wireless communication scheme? The core and novelty of the technical solution are described. A misconception that on May 7, 1895, A.S. Popov publicly presented the lightning detector is disputed. For a comparative analysis of Popov’s and predecessors’ contribution to the radio invention a synergetic approach is used.

Рассмотрены преимущества использования оркестрации для управления ресурсами автономных транспортных средств, по сравнению с существующим подходом к проектированию сетей с высокой нагрузкой. В качестве архитектуры для построения сети передачи данных использованы такие гибридные технологии, как подключение узла прямого доступа через стационарные точки и обмен данных межмашинного взаимодействия. Разработан стенд-эмулятор радиоканалов для моделирования влияния интерференции от соседних узлов и выгрузки приложений на граничные вычислительные узлы.
This article discusses the advantages of using orchestration to manage autonomous vehicle resources compared to the current design approach for high-load networks. As an architecture for building a data transmission network, hybrid technologies such as the connection of a direct access node through fixed points and exchanging machine-to-machine communication data are used. A radio channel emulator stand was developed to simulate the effect of interference from neighboring nodes and offload applications to edge computing nodes.

Предложена регулярная процедура адаптации кода, исправляющего одиночные байтовые ошибки, с целью обнаружения и коррекции байтовых ошибок в арифметико-логических устройствах(АЛУ) процессоров информационно-измерительных систем. Выявлены закономерности, определяющие соотношения между арифметико-логическими операциями и значениями контрольных разрядов линейного кода относительно данных операций. Показано, что эти закономерности позволяют сформулировать правила получения значений поправок к контрольным разрядам кода для обнаружения и коррекции одиночных байтовых ошибок при использовании алгебраического линейного кода с синдромным декодированием. Предлагаемый метод защиты от одиночных байтовых ошибок устройств обработки информации позволяет минимизировать влияние кодирования (декодирования) информации на быстродействие АЛУ процессора за счет замены циклической процедуры кодирования информации на алгебраическую с синдромным декодированием.
A regular procedure for adapting the code that corrects single bit errors for detecting and correcting byte errors in arithmetic-logic units (ALU) of information and measurement system processors is proposed. The regularities that determine the relations between arithmetic logical operations and the values of the control digits of the linear code relative to these operations are revealed. It is shown that these regularities allow us to formulate rules for obtaining correction values of code control bits for detecting and correcting single byte errors when using an algebraic linear code with syndrome decoding. The proposed method of protection against single bit errors of information processing devices allows minimizing the impact of encoding (decoding) information on the performance of the ALU processor by replacing the cyclic information encoding procedure with an algebraic one with syndrome decoding.

Artes visuais e formação docente no Brasil: contextualização das mudanças na lei (1971-2017)
Authors: Bourguignon de Lima Camila 
Published: July 2021

Resumo: Este artigo inscreve-se no contexto da formação de professores de Artes Visuais no Brasil, segundo os princípios legais norteadores da disciplina de Arte na educação básica e suas implicações nas diretrizes específicas da Licenciatura. A análise utiliza dados do Observatório do Plano Nacional de Educação em relação à adequação da formação dos professores na disciplina de Arte segundo o Censo Escolar (2018) e situando-os em meio aos dados da Licenciatura no Brasil a partir das Estatísticas da Educação Superior (2017). A discussão segue com a trajetória histórica da formação e atuação do docente de Arte com base na perspectiva da Federação de Arte-educadores do Brasil, bem como, das autoras Alvarenga e Silva (2018), Barbosa (1989) e Nunes (2007). Em virtude dos conflitos gerados pelas mudanças na Lei – da obrigatoriedade do ensino de Arte (Lei nº 5.692/1971; LDB nº 9.394/1996) à reforma do Ensino Médio (Lei nº 13.415/2017) –, a consolidação das Artes Visuais como área específica no Ensino Superior ainda é tomada por incertezas, tanto por uma narrativa de aspecto “polivalente”, quanto pela permanência da oferta da disciplina como área do conhecimento obrigatória na educação básica.

Published: July 2021

Aim. Determination of the psychological type of attitude to the patient's illness, depending on gender and age group, which will further improve communication between the patient and the dentist.Materials and methods. This article provides a psychological assessment of patients in relation to diseases of the oral cavity at a dental appointment using the adapted TOBOL technique. This technique is based on typing patients according to certain cognitive characteristics described in the article. For this study, 65 people of older age groups were interviewed.Results. The frst group of attitudes towards the disease included 27 patients (41.5%), the second – 24 (37%), the third – 14 (21.5%). 11 (45.8%) men were assigned to the frst group, 8 (33.3%) men – to the second and 5 (20.9%) – to the third group. Women showed a distribution: 16 (39%) women belonged to the frst group, 16 (39%) – to the second and 9 (22%) – to the third group, respectively. Negative attitude towards dental diseases, reluctance to treat them sharply increases in centenarians.Conclusions. With increasing age, there is a growing tendency towards pessimization and aggression. Sensitized attitudes toward illness, depression, refusal of treatment, or blame-shifting complicate diagnosis and subsequent treatment. To prevent unwanted emotions and improve the quality of communication, the dentist should be guided by an individual approach to these patients, which should be based on the basic principles of ethics and deontology. Only then will dental treatment be effective and complete.

Published: July 2021

Aim:Variations in cone tip diameter while obturation can lead to premature binding, extrusion, or poor adaptability of GP to the canal walls and promotes microleakage and ultimately endodontic failure. The purpose of this investigation was to measure the variability from the listed cone tip diameter and taper of size #25, 0.06 taper GP cones from three different brands with the help of stereomicroscope and digital micrometer.Materials and methods:45 GP points (N = 45) of Size #25 with an 0.06 taper from three different brands were divided into three groups: Group A – Diadent Group B – K3 and Group C Pro- Taper Next. Each group have 15 GP (n = 15). The diameters (D0 and D3), tapers were measured according to the ANSI/ADA Specification No. 78 using stereomicroscope (accuracy of 0.001mm) and digital micrometer. Kruskall Wallis test was to detect any significant differences between two or more groups and Mann Whitney U test for pairwise comparison. p value < 0.05 were considered as statistically significant.Results:On comparing there was significant variability within the three brands using stereomicroscopy, the standard values for D0 diameter which was 0.25 ± 0.23, Protaper Next GP cones was the similar to the standardized values compared to Diadent and K3 GP cones which were significantly different from the standard values. On comparing diameter variation at D3, Protaper Next, 0.043 ± 0.018 was once again similar to its manufacturer standard values of 0.43 ± 0.022. Diadent showed mild variation with D3 Diameter of 0.44 ± 0.017 and K3 was significantly different from the standard values K3 was 0.41 ± 0.018.Conclusions:The results of the current study indicate significant variability between GP cone brands for both diameter and taper. However, the high standard deviation values associated with most of the diameter and taper differences from manufacturer’s nominal values also suggests high variability within individual brands.
Criteria for selection to anesthesia residency programs: a survey of Canadian anesthesia program directors
Authors: Niburski Kacper , Buu Natalie 
Published: July 2021

Introduction: Applicants to specialty programs lack guidance on knowing what exactly is desired by selection committees and program directors. Anesthesia is especially opaque, given its failure to provide transparency reports nationally. This study was developed to survey Canadian anesthesia program directors about the aspects of the application package desired in an anesthesia applicant. The primary objective is to identify the preferred attributes of anesthesia applications by those mandating the selection committees.
Methods: Survey was developed via Google Surveys, and sent online over a period of two months in June and July 2020. All program directors were sent requests for filling in the survey. STATA was used for all statistical analyses. Two analyses, Mann-Whitney and ANOVA tests, were performed for comparison groups. A p < 0.05 was considered significant.
Results: Fourteen of seventeen (83%) Canadian anesthesia program directors completed the survey. Having done an anesthesia elective, good performance in it, and excellence of preclinical academic performance were considered among the most important aspects of the application package with the highest ranking important and smallest standard deviation. Any form of red flag was also considered an important criterion, again with little variation among program directors. The reference letters selected by the applicants were also important, with a personal relationship and well written reference being identified as most important (p < 0.05).
Conclusions: An applicant who has good academic performance, having anesthesia elective experience, personal, well-written reference letters, and general activity and interests that are not necessarily anesthesia-focused would be favoured by Canadian anesthesia programs.
