Abstract
Study design
A bibliometric review of the literature.

Objective
To identify the most frequently cited articles relating to the repair of intervertebral disc (IVD) and to summarize the key points and findings of these highly cited works, to quantify their impact on the developments of the disc disease treatment.

Summary of background data
IVD repair is an ever-growing and multi-disciplinary innovating treatment method for disc diseases. There are numerous literatures and related studies about it, promoting the development of the field. A comprehensive review and analysis of the most influential articles can help clarify the most effective strategy of IVD repair, and discover the promising directions for future research.

Methods
The Thomson Reuters Web of Knowledge was searched for citations of all literatures relevant to IVD repair. The number of citations, key points, categories, authorships, years, journals, countries, and institutions of publications were analyzed.

Results
The most highly cited articles in IVD Repair were published over 30 years, between 1991 and 2017. Most works (No. 41) were published between 2005 and 2009. The most-cited article was Sakai’s 2003 article which described the possibility of combining MSC and gel to repair IVD. The three most popular categories involved were Orthopedics [44], Clinical Neurology [34], Engineering, and Biomedical [24]. The three most common topics were regenerative medicine and the progenitor cells [33], biomaterials and cellular scaffolds [29], application of growth factors [25].

Abstract
Background
Water resources development promotes agricultural expansion and food security. But are these benefits offset by increased infectious disease risk? Dam construction on the Senegal River in 1986 was followed by agricultural expansion and increased transmission of human schistosomes. Yet the mechanisms linking these two processes at the individual and household levels remain unclear. We investigated the association between household land use and schistosome infection in children.

Methods
We analyzed cross-sectional household survey data (n = 655) collected in 16 rural villages in August 2016 across demographic, socio-economic and land use dimensions, which were matched to Schistosoma haematobium (n = 1232) and S. mansoni (n = 1222) infection data collected from school-aged children. Mixed effects regression determined the relationship between irrigated area and schistosome infection presence and intensity.

Results
Controlling for socio-economic and demographic risk factors, irrigated area cultivated by a household was associated with an increase in the presence of S. haematobium infection (odds ratio [OR] = 1.14; 95% confidence interval [95% CI]: 1.03–1.28) but not S. mansoni infection (OR = 1.02; 95% CI: 0.93–1.11). Associations between infection intensity and irrigated area were positive but imprecise (S. haematobium: rate ratio [RR] = 1.05; 95% CI: 0.98–1.13, S. mansoni: RR = 1.09; 95% CI: 0.89–1.32).

Conclusions
Household engagement in irrigated agriculture increases individual risk of S. haematobium but not S. mansoni infection. Increased contact with irrigated landscapes likely drives exposure, with greater impacts on households relying on agricultural livelihoods.
Mechanical strength of stainless steel and titanium alloy mini-implants with different diameters: an experimental laboratory study
Authors: Barros Sérgio Estelita , Vanz Viviane , Chiqueto Kelly , Janson Guilherme , Ferreira Eduardo 
Published: March 2021

Abstract
Background
The mechanical strength of mini-implants is a critical factor due to their small diameters. Currently, it is not possible to state whether there is a relevant difference between the mechanical properties of stainless steel (SS-MIs) and titanium alloy mini-implants (TA-MIs). The objective of this study was to test the null hypothesis that there is no difference in the mechanical strength of SS-MIs and TA-MIs, and to analyze, by scanning electron microscopy (SEM), the SS-MI, and TA-MI threads resistance to morphological damage after insertion.

Methods
A standardized sample of 504 SS-MIs and TA-MIs with diameters ranging from 1.2 mm to 1.8 mm was used. Torsional fracture was performed in 154 MIs. Flexural strength of 280 MIs was evaluated at 1 mm and 2 mm-deflection. The threads of 70 MIs were morphologically analyzed by scanning electron microscopy (SEM), before and after their insertion in high-density artificial bone blocks. Comparisons between SS-MIs and TA-MIs were performed with t tests or Mann-Whitney U tests. A multiple linear regression analysis was used to evaluate the influence of variables on the ranging of MI mechanical strength.

Results
SS-MIs had higher fracture torque. The mean difference between the SS-MIs and TA-MIs fracture torque was of 4.09 Ncm. The MI diameter explained 90.3% of the total variation in fracture torque, while only 2.2% was explained by the metallic alloy. The SS-MI group presented a higher deformation force during the 1mm and 2mm-deflection. The mean difference between the flexural strength of SS and TA-MIs at 1 mm and 2 mm-deflection was of 18.21 N and 17.55 N, respectively. There was no noticeable morphological damage to the threads of SS-MIs and TA-MIs.

Conclusions
The null hypothesis was rejected. SS-MIs were 13.2% and 20.2% more resistant to torsional fracture and deflection, respectively. The threads of the SS-MIs and TA-MIs were not damaged during the insertion and removal process. Thus, the use of SS-MI can reduce the fracture risk without increasing the MI diameter.
Analytical methodology for the analysis of vibration for unconstrained discrete systems and applications to impedance control of redundant robots
Authors: Kao Imin , Saldarriaga Carlos 
Published: March 2021

AbstractThis paper presents a general methodology for the analysis and synthesis of a positive semi-definite system described by mass, damping and stiffness matrices that is often encountered in impedance control in robotics research. This general methodology utilizes the fundamental kinematic concept of rigid-body and non-rigid-body motions of which all motions consist. The rigid-body mode results in no net change in the potential energy from the stiffness matrix of the multiple degree-of-freedom (DoF) discrete mechanical system. Example of an unconstrained discrete mechanical system is presented to illustrate the theoretical principle as applied in obtaining the free and forced vibration responses, as well as the dynamic characteristics of the system in natural frequency, $$\omega_n$$

and damping ratio, $$\zeta$$

. In addition, the methodology is applied to the impedance control of redundant robots. The rigid-body mode is equivalent to the motions of a redundant robot which result in no net change in potential energy, also called the zero-potential or ZP mode, of impedance control. Example of a redundant robot is used to demonstrate the application of the methodology in robotics. The dynamic characteristics of $$\omega _n$$

and $$\zeta$$

in the modal space are analyzed, which can be synthesized to modulate the damping of the system analytically.
“My Best Memory Is When I Was Done with It”: PE Memories Are Associated with Adult Sedentary Behavior
Authors: Ladwig Matthew A. , Vazou Spyridoula , Ekkekakis Panteleimon 
Published: March 2021

ABSTRACT
The transition from childhood to adolescence is marked by a dramatic decrease in physical activity (PA). Physical education (PE) experiences may contribute to this change but remain underresearched. Using a retrospective survey, we examined whether memories of enjoyment or nonenjoyment of PE relate to present-day (adult) attitudes, intentions, PA, and sedentary behavior. An online questionnaire was completed by 1028 American respondents (18–45 yr). The participants rated their retrospective enjoyment of PE, present attitudes and intentions for PA, as well as present PA and sedentary behavior. In addition, participants responded with their best and worst PE memories in an open-ended fashion. Retrospective enjoyment of PE was associated with present-day attitude (r = 0.37, P < 0.00001) and intention (r = 0.23, P < 0.00001) for PA, as well as negatively associated with sedentary time on the weekend (r = −0.14, P < 0.00001). The best memories related to enjoyment of the activities in class (56%), experiencing feelings of physical competence (37%), and, interestingly, 7% were not having to take PE class any longer or skipping the class. Of the worst memories, 34% related to embarrassment, 18% to lack of enjoyment, 17% to bullying, 14% to social–physique anxiety, 16% to injury, and 2% to being punished by the PE teacher. Childhood memories of PE are associated with PA attitude, intention, and sedentary behavior in adulthood. Intensified research efforts should be directed toward understanding the factors and processes that lead to the formation of memories of PE.
Bibliometric analysis on workplace cyberbullying: study protocol
Authors: Kim Yun Jin , Qian Linchao , Aslam Muhammad Shahzad 
Published: March 2021

Cyberbullying behaviour is an international public health concern all around the world due to the increasing trend of working from home during COVID-19. The prevalence of workplace cyberbullying behaviour (WCB) has been shown to be increased prior to COVID-19 among allied health professionals, such as nurses and trainee doctors. There has been a lack of bibliometric analysis on scientific publications concerning this subject; therefore, the current articles presents a protocol for bibliometric analysis of WCB. An indicator-based search will have carried out from documents on PubMed and Scopus to retrieve data from primary peer-reviewed WCB research articles using relevant keywords. Articles that involve WCB research will be included in the analysis. The dataset will identify documents all around the world, and data will be validated using the VAKS assessment tool. Analysis will be carried out by comparing the relationship among institutions, authors, countries and keywords. The dataset will be publicly accessible in the Zenodo repository. There will be no involvement of human participants; therefore, the current research does not require an ethical review. Results will be publish in a peer-reviewed journal and at related conferences
In vitro susceptibility of Trypanosoma cruzi discrete typing units (DTUs) to benznidazole: A systematic review and meta-analysis
Authors: Vela Andrea , Coral-Almeida Marco , Sereno Denis , Costales Jaime A. , Barnabé Christian , Brenière Simone Frédérique 
Published: March 2021

BackgroundChagas disease, a neglected tropical disease endemic to Latin America caused by the parasiteTrypanosoma cruzi, currently affects 6–7 million people and is responsible for 12,500 deaths each year. No vaccine exists at present and the only two drugs currently approved for the treatment (benznidazole and nifurtimox), possess serious limitations, including long treatment regimes, undesirable side effects, and frequent clinical failures. A link between parasite genetic variability and drug sensibility/efficacy has been suggested, but remains unclear. Therefore, we investigated associations betweenT.cruzigenetic variability andin vitrobenznidazole susceptibility via a systematic article review and meta-analysis.Methodology/Principal findingsIn vitronormalized benznidazole susceptibility indices (LC50and IC50) for epimastigote, trypomastigote and amastigote stages of differentT.cruzistrains were recorded from articles in the scientific literature. A total of 60 articles, which include 189 assays, met the selection criteria for the meta-analysis. Mean values for each discrete typing unit (DTU) were estimated using the meta and metaphor packages through R software, and presented in a rainforest plot. Subsequently, a meta-regression analysis was performed to determine differences between estimated mean values by DTU/parasite stage/drug incubation times. For each parasite stage, some DTU mean values were significantly different, e.g. at 24h of drug incubation, a lower sensitivity to benznidazole of TcI vs. TcII trypomastigotes was noteworthy. Nevertheless, funnel plots detected high heterogeneity of the data within each DTU and even for a single strain.Conclusions/SignificanceSeveral limitations of the study prevent assigning DTUs to differentin vitrobenznidazole sensitivity groups; however, ignoring the parasite’s genetic variability during drug development and evaluation would not be advisable. Our findings highlight the need for establishment of uniform experimental conditions as well as a screening of different DTUs during the optimization of new drug candidates for Chagas disease treatment.
Marian Inspirations for the Culture of Encounter according to Pope Francis
Authors: Wojtczak Adam 
Published: March 2021

The culture of encounter is among favourite themes of Pope Francis’s teaching. Nowadays, in the face of ever increasing feeling of ‘spiritual orphanage’, manifested by the disappearance of closeness and tenderness, he calls for Christians to go out and meet with people. At the same time, he points to Mary as the promoter of the culture of encounter. This very article is devoted to Her. I follow in the Pope’s footsteps, who distinguishes three elements of a meeting in the Gospel scene of Mary’s visit to Elisabeth: ‘Mary goes, Mary encounters, Mary rejoices’. These elements define the fundamental structure of the reflections presented here. This is about showing that Mary inspires us to go out to others, to show them closeness and tenderness, which restore the true joy of life.

El objetivo de esta investigación es describir las características que conforman los vínculos amorosos de jugadoras de baloncesto de Liga Femenina. La muestra la forman 64 profesionales en activo entre 18 y 35 años. En la evaluación se analizan las características de los vínculos amorosos. Los análisis estadísticos descriptivos y comparativos ponen de manifiesto que las jugadoras no siguen un patrón normativo de desarrollo en la formación de los vínculos amorosos. El 84,4% de las jugadoras consideran que su orientación sexual está condicionada a la vinculación emocional y no a la conducta sexual, como sería previsible. El 90,6% de las jugadoras manifiestan flexibilidad en su orientación sexual a lo largo de la vida. Como conclusión, el baloncesto de Liga femenina podría suponer un nicho ecológico en el desarrollo de los vínculos amorosos.

El estudio planteó como objetivos analizar la autoestima y su relación e influencia con la práctica deportiva, género y edad de los escolares. La muestra estuvo compuesta por 715 adolescentes, de entre 12 y 16 años (54.12% mujeres), clasificados en sedentarios, practicantes deportes individuales y practicantes deportes colectivos. Para los sujetos activos se diseñó un programa de intervención de 16 semanas de duración. Se utilizaron la Rosenberg Self Esteem Scale y el international questionnaire MVPA. La mayor autoestima corresponde con la autoestima positiva, evidenciándose diferencias significativas favorables a los hombres y a los adolescentes activos físicamente. Los adolescentes practicantes de deportes colectivos presentan mayor autoestima que los practicantes de deportes individuales. Concluyendo que la cantidad y el tipo de deporte practicado modulan la autoestima. La edad no es un factor determinante y el sexo sí influye en la autoestima. Se confirma el modelo bifactorial de la Rosenberg Self Esteem Scale.

Published: March 2021

AbstractIn this study, the mineralogical content of Abu Rusheid mylonite sample was investigated and revealed that the sample is essentially composed of quartz and feldspar (72.14% mass), muscovite (16.6% mass), and contains heavy economic polymetallic minerals of about 2.65% by mass. By studying the differences in the physical properties of this mineral content, a proposed flow sheet was set up to explain the successive physical upgrading steps for concentrating and separating the valuable minerals content and getting rid of the associated gangue minerals. Industrial, economic and strategic polymetallic minerals were identified at Abu Rusheid mylonite sample, including cassiterite, titanite, brass, kasolite, monazite, and uranothorite. A group of sulfide minerals also existed as pyrite, arsenopyrite, galena, and molybdenite in addition to the presence of fluorite and iron oxides bearing rare earth elements (REEs) and base metals. Using dry high intensity magnetic separation followed by wet gravity separation and flotation, three concentrates were obtained; heavy paramagnetic concentrate (monazite, columbite, brass, and jarosite), heavy diamagnetic concentrate (zircon, kasolite, uranothorite, cassiterite, and sulphide minerals) and muscovite concentrate for industrial uses. Physical processing of Abu Rusheid mylonite sample was carried out to produce high grade mineral concentrate used as a raw material for chemical treatment to extract economic elements that necessary for several industries.

Aim. To analyze the safety and advantages of central resection in comparison with extended hepatectomies. Methods. From June 2017 to May 2020 29 central and extended liver resections for children were performed. Central hepatic resections were carried out in 8, extended hepatectomies – in 21 patients. Preoperative investigations, intraoperative and postoperative data in both groups were analyzed.Results. The main indication for surgery was hepatoblastoma. Future liver remnant volume was significantly higher in central resections group (р = 0.003). No difference in median operative time (р = 0.94), intraoperative blood loss (р = 0.078) and blood transfusion rate (р = 0.057) were found between groups. There were no postoperative complications difference. Also no difference in hospital stay length (р = 0.3) were found.Conclusion. In comparison with extended procedures, central liver resection has similar complication rate. Central hepatectomy is a safe procedure in children with liver tumors, which allows to preserve more healthy parenchyma.

Цель исследования – провести обзор теоретической базы процедуры проведения экспертизы в сфере закупки нематериальных активов.
Материалы, методы и условия проведения исследований. Изучены нормативно-правовые акты, а также федеральный закон от 05.04.2013 г. №44-ФЗ «О контрактной системе в сфере закупок товаров, работ, услуг для обеспечения государственных и муниципальных нужд» и федеральный закон от 18.07.2011 г. №223-ФЗ «О закупках товаров, работ, услуг отдельными видами юридических лиц».
Задачи исследования – проанализировать и оценить целесообразность и эффективность привлечения внешних экспертов к процессу внутреннего контроля в сравнении с использованием труда внутреннего сотрудника в условиях государственных закупок.
Результаты исследования. В статье охарактеризован понятийный аппарат эксперта, рассмотрено понятие закупок нематериальных активов и то, какую часть из них на современном этапе занимает закупка программного обеспечения. Уделено внимание производственной процедуре закупок программного обеспечения иностранного происхождения, при этом сформирован ответ на вопрос: как выгоднее и эффективнее проводить экспертизу – с привлечением сторонних организаций или собственными силами? Также даны разъяснения по основным ключевым количественным и качественным показателям экспертизы программного обеспечения в условиях санкционного ограничения и дистантной работы.
Перспектива исследования.

В случае если закупка сделана некачественно, пострадает учет организации и эффективность использования государственных ресурсов.
ПРАВОВОЕ РЕГУЛИРОВАНИЕ ОБОРОТА ЦИФРОВЫХ ФИНАНСОВЫХ АКТИВОВ: ПРЕДПОСЫЛКИ И ОБЗОР ЗАКОНОДАТЕЛЬНОЙ НОВЕЛЛЫ
Authors: Довлатова Аракси Манвеловна 
Published: March 2021

Целью исследования является анализ и правовой обзор новых для законодательства России положений ФЗ от 31.07.2020 г. №259-ФЗ «О цифровых финансовых активах, цифровой валюте и о внесении изменений в отдельные законодательные акты Российской Федерации», актуальных предпосылок для его принятия, а также оценка реальных перспектив в дальнейшем развитии правового регулирования проблемы цифровых финансовых активов.
Методологическую базу исследования представляют собой теоретические подходы к определению правового статуса, правовой природы и места цифровых финансовых активов (в том числе в системе возможных объектов гражданских прав), их разновидностей и возможности обращения в рамках отечественного правового поля.
Результаты исследования. Одним из значимых результатов является выявление не только некоторых преимуществ законодательной новеллы ввиду ее безусловной актуальности, стратегической важности и необходимости в регламентации, но и изучение слабых сторон (к примеру, ограничивающих криптовалюту как средство платежа, несмотря на то, что как раз это теоретически и практически является одной из ее главных функций) и малоэффективности отдельных положений, которые в ближайшем будущем потребуют более детальной и углубленной проработки с учетом особенностей рассмотренных объектов. Эти обстоятельства указывают на то, что исследуемая новелла представляет собой только первые шаги законодателя по решению данной проблемы, требующей на самом деле довольно скорых поправок по причине нарастающей динамики транснационального обращения цифровых прав и активов, а также все большей цифровизации общества в целом.
Перспективу исследования составляет изучение конкретных инструментов и аспектов выпуска и обращения плодов цифровой экономики в соответствии с их сущностной спецификой – свободой, трансграничным характером и существованием фактически «над» правовыми системами, что является своего рода отражением тенденций нынешнего времени, которые в любом случае ожидают точечного и современного подхода.
