Brainstem intraparenchymal schwannoma: A case report and literature review
Authors: Kovalainen Anselmi , Haeren Roel , Paetau Anders , Lehecka Martin 
Published: October 2021

Background:
Intracranial intraparenchymal schwannomas (IS) are rare tumors that have mainly been described in case reports. Here, we report on a case of a brainstem IS and included a comprehensive literature review.

Case Description:
A 74-year-old man presented with progressive gait disturbances. CT- and MRI-imaging revealed a contrast-enhancing mass accompanied by a cyst in the dorsolateral pons. Hemangioblastoma was suspected and surgery was advised. During surgery, gross total resection of a non-invasive tumor was performed. Postoperative recovery was uneventful. Based on histopathological examination, the intraparenchymal brainstem tumor was diagnosed as schwannoma.

Conclusion:
Our extensive review illustrates that ISs are benign tumors that most often present in relatively young patients. Malignant cases have been described but form an extremely rare entity. Preoperative diagnosis based on radiological features is difficult but should be considered when peritumoral edema, calcifications, and cysts are noted. In benign cases, gross total resection of the lesion is curative. To adequately select this treatment and adjust the surgical strategy accordingly, it is important to include IS in the preoperative differential diagnosis when the abovementioned radiological features are present.

The presented article deals with the description of the socialization of basic school pupils, i.e. pupils in younger and middle school age, who fulfill the compulsory school attendance in the form of individual education (homeschooling) in the context of the legislation of the Czech Republic. In the context of fulfilling the article aim, we formulated three research questions, which were evaluated using quantitative research in the form of a questionnaire survey. The research confirmed that parents of homeschoolers significantly support their children in participating in organized leisure activities and are actively involved in mediating their child's contact with other children. In the comparison of the examined groups there were no significant differences in how the children perceive their friends, what their favorite activities are or how much time they spend with them. The difference was more noticeable in the parental approach in education, when setting some rules. This article can outline areas that can be further explored in more detail and compared in context.

Authors: Khakimova A. G. , Gultyaeva E. I. , Mitrofanova O. P. 
Published: October 2021

Background. One of the promising sources for enrichment of the common wheat (Triticum aestivum L.) gene pool with new alleles is synthetic hexaploid wheat (SHW), or allopolyploids from crossing tetraploid wheats (2n = 4x = 28, BBAA) with accessions of Aegilops tauschii Coss. (2n = 2x = 14, DD), and subsequent doubling of the chromosome number in the hybrids. Objectives of the study were to evaluate the SHW accessions from the VIR collection for resistance to Puccinia triticina Erikss. populations collected in Russia; genotype the accessions; and summarize information from the published sources concerning the resistance of the studied accessions to other harmful diseases and pests.Materials and methods. Resistance of 36 SHW accessions from the VIR collection to the populations of P. triticina was assessed in the laboratory and in the field, under artificial infection pressure, using the techniques developed by the Institute of Plant Protection. A phytopathological test and PCR markers were used to identify the Lr genes.Results and conclusion. The SHW accessions were characterized according to their resistance to the Russian populations of the wheat leaf rust pathogen. The sources of resistance in the phase of emergence and in adult plants were identified. The phytopathological test isolated three accessions with Lr23; the PCR marker of Lr21=Lr40 was found in 11 accessions, Lr39=Lr41 in 19, and Lr22a in 3. At the same time, k-65496, k-65515 and k-65517 had si multaneously Lr21=Lr40 and Lr39=Lr41, while k-65497, k-65503 and k-65508 had Lr22a and Lr39=Lr41. The analysis of published data showed that many of the studied SHW accessions were also resistant to other harmful diseases and insect pests, so they are of interest for further studying and possible use in domestic breeding.

Published: October 2021

Background. Using LD50 concentrations of the osmotic PEG 6000 to select millet genotypes during seed germination for drought resistance breeding is the best way of millet genotype differentiation according to the studied trait.Materials and methods. The millet cultivars ‘Omriyane’, ‘Kharkovskoe 57’, ‘Konstantinovskoe’, ‘Slobozhanskoe’, and the accession IR 5 were selected as the test material. Water stress was applied through five concentrations of PEG (6000 MW): 11.5%, 15.3%, 19.6%, 23.5%, 28.9%, and 0.0% (control). On the sixth day of incubation, millet seed germination was measured. The regression method for assessing LD50 (half-lethal dose) by V. B. Prozorovskii was used to theoretically substantiate the selection of an optimal osmotic concentration, which would be most accurate in identifying the level of drought tolerance in millet genotypes during seed germination.Results and conclusions: The 15.3% to 28.9% concentrations of PEG 6000 solutions had a negative effect on seed germination of millet genotypes. A strongly suppressed seed germination rate was observed at the PEG concentration of 23.5%: germination percentage in all cultivars (except for IR 5, with 56.0%) fell below 50%. Calculations according to the Verhulst logistic curve and the probit analysis by V. B. Prozorovskii’s technique showed that the mean LD50 concentration of PEG 6000 solutions for all studied genotypes was 23.03%. Thus, as a result of the analysis of our experimental data and their statistical processing, we recommended the 23.0% concentration of PEG 6000 solution as the most differentiating in terms of drought resistance in the millet seed germination phase.

The main task in choosing candidates for filling a vacancy is to meet the demand for employees in qualitative and quantitative terms. Hiring an employee is preceded by a clear understanding of the functions he will execute, tasks and job responsibilities, rights and interactions in the organization. Based on the set-out requirements, appropriate people selected for a specific position. Staff selection remains a challenge for many companies (problem). For solving these problems, it is necessary to develop information technology for the staff selection in the office of a logistics enterprise, which will provide a decision-making process in various situations for tasks of varying computational complexity(methodology). The work goals to improve the organizational management of staff support through the development of information technology for staff selection in the office of a logistics company. To achieve this goal, you need to solve the following tasks to develop the structure of information technology for the process of staff selection in the office of a logistics company; to formulate an example of staff selection by using analytic hierarchy process. As a result of developed information technology for staff selection in the office of a logistics enterprise includes: requirements formation for the office staff for the logistics enterprise; goal formation and its decomposition, including decision-making of multi-criteria and fuzzy information, information support and rule base staff selection model in the office of a logistics enterprise; multi-criteria discrete optimization; results evaluation. The practical aspect of example of staff selection in logistics office considered the usage of the analytic hierarchy process. A hierarchy of problems ‘to choose the best candidates’ creates a matrix of pairwise comparisons for all criteria. The first level is to select the best candidate. The second level is to evaluate the criteria for candidates. The third level is to fulfil the vacancy of a logistics enterprise. The difference of the developed information technology lies in the usage of fuzzy initial information, which makes it possible to be more adequately and fully evaluate applicants for vacant vacancies (originality).

The results of the research of somatic chromosomal instability: aneuploidy and polyploidy in the blood cells of high-yield Holstein cows with the productivity of more than 9000 kg have been presented in the article. The research was conducted in JSC Vaganovo, Promyshlennovsky District, Kemerovo Region on the population of Holstein cows. Sample preparation was carried out accord- ing to P. Moorhead et al. Samples were stained using the Romanowsky-Giemsa method. The authors studied 6068 metaphase plates in a group of 30 healthy animals. Aneuploidy was counted according to the practice of N.P. Bochkov et al. The authors also analysed the ecological situation in the area of keeping and breeding cattle. Studies of soil, fodder, organs and tissues in farm animals of different species confirm that heavy metal and chemical pollutants are not contaminated in Western Siberia, and their levels are within sanitary norms. Therefore, the ecological situation in the study area should be considered safe. The study shows that the frequency of polyploidy was 0.59% in the studied sample. Tetraploidy, triploidy, and hexaploidy rates were 0.33; 0.18 and 0.06, respectively, the frequency of true hypoploidy was 0.73, and the number of diploid cells was 84.7%. The data obtained can be tentatively applied as average values and can also be used to evaluate the interior of the animals.

Published: October 2021

Background and context: Surgical procedures are evolving toward less invasive and more tailored approaches to consider the specific pathology, morphology, and life habits of a patient. However, these new surgical methods require thorough preoperative planning and an advanced understanding of biomechanical behaviors. In this sense, patient-specific modeling is developing in the form of digital twins to help personalized clinical decision-making.Purpose: This study presents a patient-specific finite element model approach, focusing on tibial plateau fractures, to enhance biomechanical knowledge to optimize surgical trauma procedures and improve decision-making in postoperative management.Study design: This is a level 5 study.Methods: We used a postoperative 3D X-ray image of a patient who suffered from depression and separation of the lateral tibial plateau. The surgeon stabilized the fracture with polymethyl methacrylate cement injection and bi-cortical screw osteosynthesis. A digital twin of the patient’s fracture was created by segmentation. From the digital twin, four stabilization methods were modeled including two screw lengths, whether or not, to inject PMMA cement. The four stabilization methods were associated with three bone healing conditions resulting in twelve scenarios. Mechanical strength, stress distribution, interfragmentary strains, and fragment kinematics were assessed by applying the maximum load during gait. Repeated fracture risks were evaluated regarding to the volume of bone with stress above the local yield strength and regarding to the interfragmentary strains.Results: Stress distribution analysis highlighted the mechanical contribution of cement injection and the favorable mechanical response of uni-cortical screw compared to bi-cortical screw. Evaluation of repeated fracture risks for this clinical case showed fracture instability for two of the twelve simulated scenarios.Conclusion: This study presents a patient-specific finite element modeling workflow to assess the biomechanical behaviors associated with different stabilization methods of tibial plateau fractures. Strength and interfragmentary strains were evaluated to quantify the mechanical effects of surgical procedures. We evaluate repeated fracture risks and provide data for postoperative management.

Published: October 2021

Metal-organic frameworks (MOFs) have been extensively used as modified materials of electrochemical sensors in the food industry and agricultural system. In this work, two kinds of copper-based MOFs (Cu-MOFs) with a two dimensional (2D) sheet-like structure and three dimensional (3D) octahedral structure for H2O2 detection were synthesized and compared. The synthesized 2D and 3D Cu-MOFs were modified on the glassy carbon electrode to fabricate electrochemical sensors, respectively. The sensor with 3D Cu-MOF modification (HKUST-1/GCE) presented better electrocatalytic performance than the 2D Cu-MOF modified sensor in H2O2 reduction. Under optimal conditions, the prepared sensor displayed two wide linear ranges of 2 μM–3 mM and 3–25 mM and a low detection limit of 0.68 μM. In addition, the 3D Cu-MOF sensor exhibited good selectivity and stability. Furthermore, the prepared HKUST-1/GCE was used for the detection of H2O2 in milk samples with a high recovery rate, indicating great potential and applicability for the detection of substances in food samples. This work provides a convenient, practical, and low-cost route for analysis and extends the application range of MOFs in the food industry, agricultural and environmental systems, and even in the medical field.
A Systematic Map of Inclusion, Equity and Diversity in Science Communication Research: Do We Practice what We Preach?
Authors: Judd Karina , McKinnon Merryn 
Published: October 2021

Effective engagement with diverse stakeholders, combating misinformation and encouraging wider participation in science is core to science communication practice, and comprises much of the current focus of research in the discipline. Global events, such as the COVID-19 pandemic, have clearly shown that social inequalities also manifest within communication structures, including those of science communication. Practices which are inclusive of diverse audiences are key if we wish to engage diverse audiences in finding solutions to societal issues. Yet there is little available evidence to show which diverse, marginalised and/or excluded groups are being engaged within science communication, and via what means. This paper develops a systematic map of academic literature spanning 40 years to provide a preliminary evidence base of how diversity and inclusion within science communication research and practice is conceived and implemented. Although the discipline has shown an increased focus within the last 5 years, science communication must evolve further in order to develop a robust evidence base for understanding what constitutes inclusive science communication in both theory and practice.

Background: Patient-specific computer simulation of transcatheter aortic valve replacement (TAVR) can provide unique insights in device-patient interaction.Aims: This study was to compare transcatheter aortic valve sealing behavior in patients with bicuspid aortic valves (BAV) and tricuspid aortic valves (TAV) through patient-specific computational modeling.Methods: Patient-specific computer simulation was retrospectively performed with FEops HEARTguide for TAVR patients. Simulation output was compared with postprocedural computed tomography and echocardiography to validate the accuracy. Skirt malapposition was defined by a distance larger than 1 mm based on the predicted device-patient interaction by quantifying the distance between the transcatheter heart valve (THV) skirt and the surrounding anatomical regions.Results: In total, 43 patients were included in the study. Predicted and observed THV frame deformation showed good correlation (R2 ≥ 0.90) for all analyzed measurements (maximum diameter, minimum diameter, area, and perimeter). The amount of predicted THV skirt malapposition was strongly linked with the echocardiographic grading of paravalvular leakage (PVL). More THV skirt malapposition was observed for BAV cases when compared to TAV cases (22.7 vs. 15.5%, p &lt; 0.05). A detailed analysis of skirt malapposition showed a higher degree of malapposition in the interleaflet triangles section for BAV cases as compared to TAV patients (11.1 vs. 5.8%, p &lt; 0.05).Conclusions: Patient-specific computer simulation of TAVR can accurately predict the behavior of the Venus A-valve. BAV patients are associated with more malapposition of the THV skirt as compared to TAV patients, and this is mainly driven by more malapposition in the interleaflet triangle region.
