Effects of physical activity on the progression of diabetic nephropathy: a meta-analysis
Authors: Cai Zixin , Yang Yan , Zhang Jingjing
Published: December 2020

Background: Diabetic nephropathy (DN) is an important microvascular complication of diabetes. Physical activity (PA) is part of a healthy lifestyle for diabetic patients; however, the role of PA in DN has not been clarified. Our aim was to conduct a meta-analysis to explore the association between PA and DN risk.

Methods: PubMed, Embase, Cochrane Library and Web of Science were systematically searched for articles examining PA in diabetic patients and its effect on renal function. Standardized mean differences (SMDs) and odds ratios (ORs) with 95% confidence intervals (CIs) were calculated. The study protocol is registered with PROSPERO (CRD42020191379).

Results: A total of 38991 participants were identified from 18 studies. The results indicated that PA was associated with increases in the glomerular filtration rate (SMD = 0.01, 95% CI = [0.02–0.17]) and decreases in the urinary albumin creatinine ratio (SMD = −0.53, 95% CI: −0.72 to −0.34), rate of microalbuminuria (OR = 0.61, 95% CI = [0.46–0.81]), rate of acute kidney injury (OR = 0.02, 95% CI = [0.01–0.04]), rate of renal failure (OR = 0.71, 95% CI = [0.52–0.97]) and risk of DN in patients with Type 1 diabetes (OR = 0.67, 95% CI = [0.51–0.89]).

Conclusions: This meta-analysis indicated that PA is effective for improving DN and slowing its progression; however, more high-quality randomized controlled trials are required on this topic.
An epithelial–mesenchymal transition-related long noncoding RNA signature correlates with the prognosis and progression in patients with bladder cancer
Authors: Tong Hang , Li Tinghao , Gao Shun , Yin Hubin , Cao Honghao , He Weiyang
Published: December 2020

Bladder cancer is a common malignant tumour worldwide. Epithelial–mesenchymal transition (EMT)-related biomarkers can be used for early diagnosis and prognosis of cancer patients. To explore, accurate prediction models are essential to the diagnosis and treatment for bladder cancer. In the present study, an EMT-related long noncoding RNA (lncRNA) model was developed to predict the prognosis of patients with bladder cancer. Firstly, the EMT-related lncRNAs were identified by Pearson correlation analysis, and a prognostic EMT-related lncRNA signature was constructed through univariate and multivariate Cox regression analyses. Then, the diagnostic efficacy and the clinically predictive capacity of the signature were assessed. Finally, Gene set enrichment analysis (GSEA) and functional enrichment analysis were carried out with bioinformatics. An EMT-related lncRNA signature consisting of TTC28-AS1, LINC02446, AL662844.4, AC105942.1, AL049840.3, SNHG26, USP30-AS1, PSMB8-AS1, AL031775.1, AC073534.1, U62317.2, C5orf56, AJ271736.1, and AL139385.1 was constructed. The diagnostic efficacy of the signature was evaluated by the time-dependent receiver-operating characteristic (ROC) curves, in which all the values of the area under the ROC (AUC) were more than 0.73. A nomogram established by integrating clinical variables and the risk score confirmed that the signature had a good clinically predict capacity. GSEA analysis revealed that some cancer-related and EMT-related pathways were enriched in high-risk groups, while immune-related pathways were enriched in low-risk groups. Functional enrichment analysis showed that EMT was associated with abundant GO terms or signaling pathways. In short, our research showed that the 14 EMT-related lncRNA signature may predict the prognosis and progression of patients with bladder cancer.
A low [CII]/[NII] ratio in the center of a massive galaxy at z = 3.7: Evidence for a transition to quiescence at high redshift?

Published: December 2020

Understanding the process of quenching is one of the major open questions in galaxy evolution and crucial insights may be obtained by studying quenched galaxies at high redshifts at epochs when the Universe and the galaxies were younger and simpler to model. However, establishing the degree of quiescence in high-redshift galaxies is a challenging task. One notable example is Hyde, a recently discovered galaxy at zspec = 3.709. Equally as compact (r1/2 ∼ 0.5 kpc) and massive (M* ∼ 1011 M⊙) as its quenched neighbor Jekyll, it is also extremely obscured yet only moderately luminous in the sub-millimeter. Panchromatic modeling has suggested it could be the first galaxy found in transition to quenching at z >  3, however, the data are also consistent with a broad range of star-formation activity, from fully quenched to moderate star-formation rates (SFR) in the lower scatter of the galaxy main-sequence. Here, we describe Atacama Large Millimeter Array observations of the [C II] 157 μm and [N II] 205 μm far-infrared emission lines. The [C II] emission within the half-light radius is dominated by ionized gas, while the outskirts are dominated by photo-dissociation regions or neutral gas. This suggests that the ionization in the center is not primarily powered by ongoing star formation, and is instead coming from remnant stellar populations formed in an older burst or from a moderate active galactic nucleus . Accounting for this information in the multi-wavelength modeling provides a tighter constraint on the star formation rate of SFR = 50−18+24 M⊙ yr−1 yr−1. This rules out fully quenched solutions and favors SFRs more than factor of two lower than expected for a main-sequence galaxy, confirming the nature of Hyde as a transition galaxy. These results suggest that quenching happens from inside-out and starts before the galaxy expels or consumes all its gas reservoirs. Similar observations of a sample of massive and obscured galaxies would determine whether this is an isolated case or the norm for quenching at high redshift.

Context. T Tauri has long been the prototypical young pre-main-sequence star. However, with increasing resolution and sensitivity, T Tauri has now been decomposed into a triple system with a complex disk and outflow geometry.

Aims. We aim to measure the brightness of all three components of the T Tauri system (T Tau N, T Tau Sa, and T Tau Sb) in the mid-infrared in order to obtain photometry around the ∼9.7 μm silicate feature. This allows us to study their variability and to investigate the distribution of dust and the geometry of circumstellar and circumbinary disks in this complex system.

Methods. We observe the T Tauri system with the Very Large Telescope (VLT)/VISIR-NEAR instrument, performing diffraction-limited imaging in the mid-infrared. With kernel phase interferometry post-processing of the data, and using the astrometric positions of all three components from VLT/SPHERE, we measure the three components’ individual brightnesses (including the southern binary at an angular separation down to ∼0.2λ/D) and obtain their photometry. In order to validate our methods, we simulate and recover mock data of the T Tauri system using the observed reference point-spread function of HD 27639.

Results. We find that T Tau N is rather stable and shows weak silicate emission, while T Tau Sa is highly variable and shows prominent silicate absorption. T Tau Sb became significantly fainter compared to data from 2004 and 2006, suggesting increased extinction by dust. The precision of our photometry is limited by systematic errors in kernel phase interferometry, which is consistent with previous studies using this technique.

Conclusions. Our results confirm the complex scenario of misaligned disks in the T Tauri system that had been observed previously, and they are in agreement with the recently observed dimming of T Tau Sb in the near-infrared. Our mid-infrared photometry supports the interpretation that T Tau Sb has moved behind the dense region of the Sa-Sb circumbinary disk on its tight orbit around Sa, therefore suffering increased extinction.
Dynamics of charged dust in the orbit of Venus
Authors: Zhou Lei , Lhotka Christoph , Gales Catalin , Narita Yasuhito , Zhou Li-Yong
Published: December 2020

We study the dynamics of co-orbital dust in the inner Solar System, that is, the role of the solar radiation pressure, the Poynting-Robertson effect, the solar wind, and the interplanetary magnetic field, on the location, width, and stability of resonant motion of charged and micron-sized dust grains situated in the 1:1 mean motion resonance with Venus. We find deviations and asymmetry between L4 and L5 in the locations of the libration centers and libration width caused by nongravitational effects with analytical and numerical methods. The triangular Lagrangian points become unstable when solar radiation pressure, the Poynting-Robertson effect, and solar wind drag are considered. The Lorentz force could further destabilize the orbits, especially for small dust particles. We also compare the circular and/or elliptic restricted three-body model and a more complete model that includes all planets.

In the context of the global digital transformation, the most important factors determining socio-economic progress are the specific properties of human capital that are inherent only in the digital economy. In the new conditions, the role of integratively distributed network interaction of participants of global, national, corporate and social networks in the training of highly qualified specialists with new information and network skills and competencies is growing, a new form of human capital is emerging - network education capital (network education capital). On the basis of an interdisciplinary approach (economics, sociology, psychology, pedagogy, etc.), positive externalities are described that arise as a result of the inclusion of education in network communication processes. One of the main specific features of modern education is the departure from its linearity and verticality. It is shown that the network formation capital acquires the properties of a specific asset that brings a quasi-rent, and acts as a social elevator only if the involvement of more entities in the network increases

Authors: Romanova Irina K.
Published: December 2020

The subject of these studies is to propose an approach to the formation of collective design competencies in the new digitalization environment. The relevance of the task in various fields of activity is shown. It is noted that while the latest information technologies, which appeared in the era of universal digitalization, are not yet sufficiently applied to build the competencies of designers as part of collective activities, the training of specialists is mainly carried out as part of individual projects. The studies were conducted on the basis of the actual applied task of collective design of group control of heterogeneous robots. The unique relationship of the object (group control) and the method of its research (group parallel design) is noted. A connection is established between the features of the ongoing project of group control of robots and the formation of in-depth competencies in the training of specialists in robotics and mechatronics. New representations of functional models are formed taking into account the needs of new information technologies. Within the framework of parallel and compositional design technologies based on CDP4 ™- and System Composer ™, models have been obtained that implement functional schemes for group control of heterogeneous robots in two versions, suitable for use both for educational purposes to form team design competencies and for real projects.

It looks at difficulties of obtaining university level education, problems of interpersonal communication and socialization, points out the leading role of digital technologies in the modern world and necessity of their introduction into the inclusive educational environment. Based on the results of MAI students survey we describe difficulties of communication with physically challenged peers, discuss different forms of psychological assistance inside the educational process. It turned out that contemporary youth is conscious of inclusive education problems. They are interested in removal of existing barriers and expanding social boundaries of communication including with people suffering from various health restraints. Young people also think that inadequate awareness of the problem leads to inaction and makes it impossible to give necessary psychological support to peers with special needs. The paper also discusses psychological and pedagogical support for people with special needs that can become the most accessible type of help in the future, and how introduction of digital technologies into inclusive education helps to solve main problems of their socialization and inclusion into society. We also touch an important question of the need for special correction-al training of the academic teaching staff in the inclusive education development system inside an institute of higher education.

In the field of training higher educational institution teachers, an era of significant change is beginning. For long, this area has remained the most conservative and was not noticeably subject to changes in society. However, the situation has changed dramatically. First of all, this is due to the rapid development of other areas of human activity, and in particular digital technologies. It is already difficult to imagine a modern society without such technologies, and the main task of a higher education teacher is precisely to train highly qualified specialists with new competencies to solve the challenges facing humanity. Strengthening the explicit link between the needs of society and the objectives of higher education is one of the prerequisites for significant changes in the field of education. The concept of training a teacher of higher education for the future today is largely determined by the development trends of digital technologies. The absence of objective reasons to assume the cessation of the use and development of digital technologies allows us to make an assumption that virtual educational worlds will appear in the foreseeable future, which will become the same familiar environment for acquiring the necessary competencies as higher schools existing in the physical world. This largely determines the relevance of the chosen research topic and determines the need for a thorough analysis of the educational technologies used in the training of teachers. The purpose of this work is, using a combination of analysis, synthesis, idealization and analogy, to generalize at the national and international levels the existing ideas about effective approaches to teaching a higher education teacher, including continuous improvement of competence in his professional field, and modern practice of using digital technologies, and also highlight the most interesting new learning experiences. The necessity of applying the so-called “integrated approach to teaching a higher education teacher” by the authors is proved. The main advantages and disadvantages of using digital technologies are highlighted. Reasonable conclusions are made on the existence of an ideal recipe for combining accumulated educational practices in the framework of traditional education and digital technology.

The origin and development of e-learning methods in Russia and other countries is due to steady progress in the field of information and communication technologies and the general informatization of the educational process, the creation of a global environment for the mutual integration of cultures and disciplines, as well as the establishment of continuing open-ended education that underlies post-industrial (information) society. Under the influence of these processes, there is a need for new, more advanced educational practices, which is the reason for the transformation of both the essence of national education and its formal side. Nowadays, a person should possess not only a certain amount of useful information, but also the ability to learn: search and find the necessary information, use various sources to get out of difficult situations, continuously expand the range of one’s own competencies, and constantly develop, keeping up with what is happening around. In the framework of the modern educational paradigm, the student is considered as a subject of knowledge, and not an object of pedagogical influence. In the early to mid2010s, active contribution to this is made by e-learning (electronic learning, e-learning), which must be used in educational institutions of various types and at different levels of the educational vertical. It makes it possible to integrate into the global scientific community, to become subjects of the interaction of cultures, including the exchange of spiritual values. The introduction of e-learning is one of the key tasks in the context of the modernization of national education. The term «electronic learning» is transmitted into Russian in various ways. The most popular options are: “distance learning / education”, “mobile learning”, “virtual learning”. The European Commission interprets “e-learning” as “the use of new multimedia and Internet technologies to improve the quality of education by improving access to resources and services, as well as remote knowledge sharing and collaboration”. In this study, the term “e-learning” will correspond to the phrase “electronic learning”. This is a learning process based on interactive electronic means of storing and providing information: the Internet, corporate networks, and CD-ROMs.
