Authors: Rallo Michael S. , Ashraf Omar , Jumah Fareed , Gupta Gaurav , Nanda Anil
Published: March 2020

OBJECTIVE

Engagement in research and scholarship is considered a hallmark of neurosurgical training. However, the participation of neurosurgical trainees in this experience has only recently been analyzed and described in the United States, with little, if any, data available regarding the research environment in neurosurgical training programs across the globe. Here, the authors set out to identify requirements for research involvement and to quantify publication rates in leading neurosurgical journals throughout various nations across the globe.

METHODS

The first aim was to identify the research requirements set by relevant program-accrediting and/or board-certifying agencies via query of the literature and published guidelines. For the second part of the study, the authors attempted to determine each country’s neurosurgical research productivity by quantifying publications in the various large international neurosurgical journals—World Neurosurgery, Journal of Neurosurgery, and Neurosurgery—via a structured search of PubMed.

RESULTS

Data on neurosurgical training requirements addressing research were available for 54 (28.1%) of 192 countries. Specific research requirements were identified for 39 countries, partial requirements for 8, and no requirements for 7. Surprisingly, the authors observed a trend of increased average research productivity with the absence of designated research requirements, although this finding is not unprecedented in the literature.

CONCLUSIONS

A variety of countries of various sizes and neurosurgical workforce densities across the globe have instituted research requirements during training and/or prior to board certification in neurosurgery. These requirements range in intensity from 1 publication or presentation to the completion of a thesis or dissertation and occur at various time points throughout training. While these requirements do not correlate directly to national research productivity, they may provide a foundation for developing countries to establish a culture of excellence in research.

OBJECTIVE

Neurosurgical training poses particular challenges in Australia and New Zealand, given the large landmass, small population, and widely separated, often small, neurosurgical units. Such factors have necessitated a move away from autonomous, single-institution–based training to the selection of trainees by a centralized binational process. The success of this system is based on rigorous standardized evaluation of candidates’ academic achievements, anatomical knowledge, references, and interview performance. Similarly, the accreditation of hospitals to train successful candidates has been standardized. The authors review the evolution of trainee selection and the accreditation of training posts in Australia and New Zealand.

METHODS

The records of the Neurosurgical Society of Australasia Surgical Education and Training Board were reviewed for documents pertaining to the selection of neurosurgical trainees and the accreditation of training posts. Application records and referee scores from 2014 to the present were reviewed to encompass process changes, in particular the change from written referee reports to standardized interviews of referees. Surgical logbook case numbers for 23 trainees completing training in 2016, 2017, and 2018 were collated and presented in an aggregated, de-identified form as a measure of adherence to accreditation standards. Written evaluations of the training experience were also sought from two trainees reflecting on the selection process, the quality of training posts, and training limitations.

RESULTS

While a time-consuming process, the method of obtaining referee reports by interview has resulted in a wider spread of scores, more able to separate high- and low-scoring applicants than other components of the selection process. Review of the training post accreditation records for the last 2 years showed that adherence to standards has resulted in loss of accreditation for one unit and shortened periods of review for units with more minor deficiencies. Two applications for accreditation have been denied. Examination of caseload data showed that trainees more than fulfill minimum requirements in accredited training posts, confirming the robust nature of this aspect of unit accreditation.

CONCLUSIONS

A key factor determining the success of neurosurgical training in Australia and New Zealand has been a willingness to evolve selection and other processes to overcome challenges as they become apparent. According to available analyses, the revised referee process and strict accreditation standards appear effective. The benefits and challenges of the current training system are discussed in the context of a paucity of international literature.

By the end of 2012, the Government of the Russian Federation is to approve the State Program Development of the Pharmaceutical and Medical Industries for 20132020, which includes the current Federal Target-Oriented Program Pharma-2020. One of the objectives within the State Program prepared by the Ministry of Industry and Trade is to increase the share of domestically produced drugs and medicinal products in overall consumption by the public healthcare services of the Russian Federation by 48%. However, the term domestically produced drug still remains to be legislatively defined. According to the draft resolution issued by the Ministry of Industry and Trade in May 2012, a domestic drug should mean a drug whose production cycle in the territory of the Russian Federation starts from a substance or a ready-toconsume formulation. Until 2014, the Ministry was ready to regard even those drugs whose packaging was made in Russia as Russian ones. However, no further steps followed. Therefore, the question pertaining to which drugs and which produced by which pharmaceutical companies should be regarded as domestic drugs remains open. Actors of the Russian pharmaceutical industry share their opinions.
The Contribution of Ribosomal Protein S1 to the Structure and Function of Qβ Replicase
Authors: Kutlubaeva Z. Sh. , Chetverina Е. V. , Chetverin A. B.
Published: March 2020

The high resolution crystal structure of bacterial ribosome was determined more than 10 years ago; however, it contains no information on the structure of the largest ribosomal protein, S1. This unusual protein comprises six flexibly linked domains; therefore, it lacks a fixed structure and this prevents the formation of crystals. Besides being a component of the ribosome, protein S1 also serves as one of the four subunits of Q replicase, the RNA-directed RNA polymerase of bacteriophage Q. In each case, the role of this RNA-binding protein has been thought to consist in holding the template close to the active site of the enzyme. In recent years, a breakthrough was made in studies of protein S1 within Q replicase. This includes the discovery of its paradoxical ability to displace RNA from the replicase complex and determining the crystal structure of its fragment capable of performing this function. The new findings call for a re-examination of the contribution of protein S1 to the structure and function of the ribosome.

Currently, there are no approved therapies for targeted prevention and treatment of Ebola hemorrhagic fever. In the present work, we describe the development of a eukaryotic expression system for the production of three full-length chimeric antibodies (IgG1-kappa isotypes) GPE118, GPE325, and GPE534 to the recombinant glycoprotein of the Ebola virus (EBOV GP), which is a key factor in the pathogenicity of the disease. The immunochemical properties of the obtained antibodies were studied by immunoblotting and indirect, direct, and competitive ELISA using the recombinant EBOV proteins rGPdTM, NP, and VP40. The authenticity of the antibodies and the absence of cross-specificity with respect to the structural proteins NP and VP40 of the Ebola virus were proved. The epitope specificity of the resulting recombinant antibodies was studied using commercial neutralizing antibodies against the viral glycoprotein. The recombinant antibodies GPE118, GPE325, and GPE534 were shown to recognize glycoprotein epitopes that coincide or overlap with the epitopes of three well-studied neutralizing anti-Ebola virus antibodies.

Carriage frequencies of alleles and genotypes of the TGFB1 gene polymorphous loci -509CT (rs1800469), 869TC (rs1982073), 915GC (rs1800471), which affect the level of cytokine TGF-1 production, were analyzed in the patients of Russian ethnic descent with myocardial infarction (MI) (406 cases) and in the control group of the same ethnic descent (198 controls). Significant association with MI was observed in carriage frequencies of the allele TGFB1*-509T (p=0.046, OR =1.45, 95% CI: 1.02-2.06), genotypes TGFB1*869T/T (p=0.0024, OR =1.75, 95% CI: 1.22-2.51), and TGFB1*915G/G (p=0.048, OR=1.76, 95% CI: 1.05-2.97). Linkage disequilibrium analysis for these SNPs has shown that the associations revealed can be considered to be independent. A complex analysis of MI association with combinations of alleles/genotypes of said SNPs indicates their cumulative effect. An analysis of susceptibility to early-onset MI ( 50 years old) revealed a positive association of the allele TGFB1*-509T (p=0.002, OR=2.24, 95% CI: 1.35-3.71) and genotype TGFB1*869T/T (p=0.008, OR=1.93, 95% CI: 1.18-3.15), as well as their additivity. An analysis of susceptibility to recurrent MI revealed an association of the genotype TGFB1*-509T/T (p=0.0078, 0R=2.60, 95% CI: 1.28-5.28). The results obtained indicate the important role of the TGFB1 gene in susceptibility to MI, including early-onset and recurrent MI, in Russians.

Published: March 2020

AISI 316L is widely used for implantation in orthopedic surgery due to its good corrosion resistance, mechanical properties and low cost. However, AISI 316L is not well suited for biocompatibility with the body, so implant material with AISI 316L can’t be used for a long time. One way to improve the corrosion resistance and mechanical properties of AISI 316L is to perform a surface treatment such as sputtering. This study discusses the effect of deposition sputtering TiN of 60, 90, 120 and 150 minutes on roughness and surface hardness at a ratio of argon gas and nitrogen to 80% Ar:20% N2. The results of the surface roughness value of the TiN sputtering layer deposited to AISI 316L for 60, 90, 120, and 150 minutes were 0.02 μm, 0.04 μm, 0.06 μm, and 0.04 μm respectively. This shows that the coating time of TiN in AISI 316L has no significant influence on value of surface roughness. Surface hardness results at 60, 90, 120, and 150 minutes were obtained with 268 HVN, 275 HVN, 278 HVN and 282 HVN. Increased hardness value, as the TiN thin layer has a higher hardness value compared to AISI 316L. The longer the deposition time, the more layers are formed and the layer becomes thicker. With the thickness of the layer, the density at the grain boundary increases. Because the higher density leads to grain growth, in which form micropores.

This study aimed that to examine the extent of the diversity of morphological characters from random cross-breeding with mixtur  parental sources, then packaged to add material to the subject matter of Vertebrate Animal Systematics as a reference source for students of Biology Education Study Program FPMIPA IKIP Mataram. This research is a case study based on explorations descriptive that are presented qualitatively. A total of 24 cats were obtained by road sampling. Morphological characters include body color, color pattern, fur length, and tail length. The results showed that the frequency of appearance of morphological characters due to marriage in the same lineage led to the characteristics of mixtur race cats by 90.7% and 8.3% of domestic cats. Inline marriages (between siblings/mothers) tend to show large-medium round, high morphology, solid color patterns, thick fur, and long tails. While the appearance of short-tailed morphological characters leading to domestic cats and gray colors in low frequencies is thought to be the result of lethal and heterozygous genes derived.

The main purpose of Indonesian national education system is to create a Pancasilais human being, characterized by living with religious values and noble humanity. Islamic higher education then played a significant role by developing an education system that integrated science and religion into their curriculum by put some specific Islamic theology course/subject onto their science department. In consequence, the paradigm learning model which is phylosophicaly, holistic, and integrative is strongly needed. This kind of learning model would give birth to an aksiological aspect by emerging the spiritual factor. Thereby, religion would became  a value system that always embedded in every science course/subject.

In addition to these activities, the Ancar River is also used as a place for domestic waste disposal and disposal of the tofu waste industry so that it can have a negative impact on water resources, including causing a decrease in water quality. The Annelida response to environmental changes can be used to see the effect of various activities, such as the impact of industrial activities, agriculture, and land use. This study aims to assess the community structure of Annelida as bioindicators of the waters against the content of polluted material found in the Ancar River. This research is descriptive explorative, using quantitative and qualitative approaches. This study uses the "Sampling Purposive" method, which is the determination of the observation station based on the use of land around the Ancar River environment. Each sampling station is carried out in 3 points, namely left, center and right of the river. Annelida obtained in the Ancar River consist of two classes namely Oligochaeta and Hirudinea. Oligochaeta class consists of Tubifex sp., Lumbricus terrestris, Hirudinea class consisting of Hirudo medicinalis. The community structure of Annelida can be used as a indicator of river pollution. From the results of the study it was found that the Ancar River had experienced pollution caused by organic matter both from household waste and tofu industrial waste. Based on the BOD value it is known that station 1 is categorized as uncontaminated location, stations 2 and 4 are lightly polluted, and stations 3, 5 and 6 are moderately polluted.

Verbal scientific communication skills observed in this study include: asking questions, answering questions, contributing ideas / opinions, responding to other students' opinions, and conveying the results of the discussion. Based on the results of the study concluded that the oral communication skills of Al-Azhar Kayangan high school students through learning the integration model of local wisdom are still in the low category. A skill cannot be taught in a short time so it needs to be practiced repeatedly so that students become more skilled. Further research is needed to be related to non-verbal communication skills at the same location and students so that observation of students' communication skills is more comprehensive.

Ethnomathematics: past and future
Authors: D'Ambrosio Ubiratan
Published: March 2020

Each culture develops ways, since the Paleolithic era, styles and techniques of doing, and responses to the search of explanations, of understanding and of learning. They basically respond to “how” and “why”. In the human species, early attempts to explain and to understand lead to the search for origins, which leads to myths. All these are organized as systems of knowledge and religions.  These systems of knowledge lead to the concept of Ethnomathematics. After a report on the practice of Ethnomathematics and the evolution of theoretical reflections since pre-historic times to the present, I will discuss some new trends I recognize in the theory and practice of Ethnomathematics. I will refer to different cultural environments and the consequents of the growing migratory dynamics in the entire world. The move towards globalization and internationalization of education favors the reinforcement of local considerations. Glocalization has consequences for the future of Ethnomathematics as research program with pedagogical implications.
Stars in the sky: Pleiades invite plenitude — an ethnomathematics memoir in Central Brazil
Authors: Ferreira Mariana Kawall Leal
Published: March 2020

This is a day, a month, a year, and a few decades — dry and rainy seasons included — in real-life mathematics of the Kisêdjê Indigenous People of the Wawi Territory, Central Brazil. According to the Kisêdjê, aka Suyá, the sun and the stars rule the sky, while people, animals, and plants create reality on earth. We are in the state of Mato Grosso, at 11 degrees, 45 minutes South latitude; and 53 degrees, 1 minute West longitude. Starting in 1981, this ethnomathematics memoir traces factual moments of my life as a mathematics educator in indigenous schools. Hands-on, real-life activities are included in the “Teacher’s Notebook.” This includes fishing expeditions, and excursions to local dispensaries and far away hospitals. My objective is to show that mathematics education, including map-making, provides important resources in the fight for sovereignty and autonomy of Indigenous Peoples in Brazil, the Americas, and worldwide.

Authors: Mafra José Ricardo e Souza
Published: March 2020

This paper provides a discussion related to the development of educational practices, having as basic assumptions the planning, organization and implementation of an ethnographic field research, from the production of decorated and incised bowls, by women artisans, Aritapera region, state from Pará, northern Brazil. We present the initial development of the proposal, carried out in the Aritapera region, based on joint planning with teachers from the region, based on the design of a set of local activities for later implementation in the classroom. With this investigation, it is expected to contribute to the field of research in ethnomathematics, by bringing empirical reflections aiming at the implementation of local curricular practices, based on good educational practices.
Revising the history of number: how Ethnomathematics transforms perspectives on indigenous cultures
Authors: Owens Kay , Muke Charly
Published: March 2020

Many accounts of the history of number rely on written evidence such as clay, stone, and wood engravings or paintings. However, some of the oldest cultural groups (between 5 000 and 30 000 years old) have had only recent contact with the rest of the world, namely between 80 and 140 years ago but these were oral cultures without written records. Finding out about their understanding of number has involved analysis of the types of counting but also how counting related to the rest of their cultural relationships. There is some surprising evidence of diversity of number systems, longevity of the systems, and the interplay with cultural practices that begs respect for Indigenous cultures. Brief summaries of this history of number in Papua New Guinea and Oceania and the diversity of systems is followed by how this new knowledge can inform school mathematics learning in any part of the world.

Indigenous games play an important role in various communities. Despite research indicating that these games can be used to advance and create a connection between classroom activities and the real life contexts, the connection has not been explored adequately to make this a reality in many mathematics classrooms. This Article reports on the various indigenous games that are a feature in South Africa as well as the Southern Africa region. The Article identifies a number of indigenous games that are popular in South Africa and how such games have been used to promote cultural heritage. This article also discusses examples of the use of such games in the process of teaching and learning of mathematics in schools.
