Objective: to analyze the expected economic transformations in the 21st century in various countries of the world. Methods: abstract-logical method, methods of modeling of socio-economic self-organization, methods of long-term forecasting of world dynamics, theory of institutional matrices.Results: based on the performed analysis, the following conclusions are made: 1) in the coming decades, a complex continuum of types, transitions, combinations and forms of economic structures will be observed in the world (with an increase in the proportion of post-industrial forms). At the same time, there will be a shift towards strengthening distributive institutions in developed countries and a shift towards strengthening market institutions in developing countries that continue the processes of economic and socio-political modernization; 2) the process of internationalization of the labor force will be intensified (due to the development of remote employment) along with the internationalization of capital; 3) a new technological wave (2030s – 2070s) will bring new resources and expand the sphere for production and services, which will support economic growth in both developed and developing countries; 4) at the same time in some areas, in particular in medicine, a very significant regulation of economic activity is inevitable, while in other areas, in particular in robotics, economic mechanisms of a market-corporate type may strengthen; 5) thus, the most important task in the coming decades is to increase the flexibility of socio-economic development of all countries of the world, namely, gaining the ability to regulate the ratio of market and distribution mechanisms depending on the spheres of activity and tasks to be solved without the pressure of ideological dogmas.Scientific novelty: based on the historical trends analysis using the theory of institutional matrices, a forecast of economic transformations in the 21st century is made for the countries of various types and the expected features of these transformations are substantiated.Practical significance: the proposed methods of long-term forecasting can be used in strategic planning systems in the Russian Federation.
High-intensity Focused Ultrasound In Interventricular Septal Myocardial Ablation: Effects Of Coronary Flow
Authors: Ren Fei , Sui Yulong , Gong Xiaobo , Xing Quansheng , Wang Zhibiao 
Published: June 2022

Abstract
Background
High-intensity focused ultrasound (HIFU) can generate necrotic damage in deep tissues through thermal ablation and cavitation, without significant damage to the surrounding tissues. The high blood perfusion of heat affects the deposition of energy. The aim of this study was to evaluate the effect of cooling of coronary blood flow for high-intensity focused ultrasound ablation.
Methods
Continuous and pulsed HIFU (2000 J) at duty cycles (DCs) of 100% and 20% were examined for their capacity to ablate the perfused porcine heart tissue in vitro. After ablation, gray scale changes and pathological features were observed or measured, and tissue necrosis area and volume were calculated.
Results
The cardiomyocytes in the lesions underwent necrosis with a clear boundary. The endocardium was intact without necrosis. The three-dimensional morphology of the lesions appeared approximately as ellipsoids. With the increase of perfusion speed, the necrotic volume in the target area was gradually reduced.
Conclusions
HIFU has the potential to become a new minimally invasive surgery for ventricular septal myocardial ablation. Reducing coronary blood flow can improve the ablation effect.
Molecular dynamic simulation suggests stronger in-silico docking of Omicron spike on ACE2 than Wild but weaker than Delta SARS-CoV-2 variants can be blocked by engineered S1-RBD fraction
Authors: Santra Dipannita , Maiti Smarajit 
Published: June 2022

Abstract
Background: The SARS-CoV-2 claimed millions lives globally. Occurring from Wuhan (Wild-type) in December, 2019, it constantly mutated to Omicron (B.1.1.529) the predecessor to Delta. Objectives: Omicron having ~32 spike-mutations has variable infectivity-multiplicity-immunoinvasive properties. Understanding of its mutational-effect on ACE2-binding/disease-severity and developing preventive/therapeutic strategies are important. Methods: The binding-affinities of Wuhan/Delta/Omicron spikes (PDB/GISAID/SWISS-MODEL) were docked (HADDOCK2.4) with ACE2 and compared by competitive-docking (PRODIGY). The protein structural-stability was verified by kinetic-data/Ramachandran-plot (Zlab/UMassMedBioinfo). After several trials, a 59 amino-acid (453ARG-510VAL) peptide-cut (Expasy-server) of the Wild-spike-RBD with some desired mutants (THR500SER/THR500GLY/THR500ALA/THR500CYS) were blindly/competitively docked (PyMOL-V2.2.2) to block the Omicron-ACE2 binding. We examined Molecular-Dynamic-Simulation (iMOD-server, with 9000-cycles/300k-heating/1-atm pressure for system-equilibration for 50ns-run) of ACE2 and two CUTs with different SARS-CoV-2 variants. Result: The binding-affinity of Omicron-ACE2 is slightly higher than the rest two in competitive-docking-setup. During individual (1:1) docking, Omicron showed little higher than Wild-type but much weaker binding-affinity than Delta. Competitive-docking suggests that ten H-bonding (1.3Å-2.4Å) with highly favorable energy-values/Van-der-Walls-force/Haddock-score for more stable-binding of Omicron-RBD with ACE2. Blind-docking of different CUTs (wild/mutants) and Omicron to ACE2 completely rejected the Omicron-RBD from ACE2-target. The best blocking/binding affinity of-16.4 and -13Kcal/mole were observed in case of THR500SER and THR500GLY, respectively with multiple H-bonding 1.9Å-2.2Å. These are supported by the MD-simulation results. Conclusion: So the spike binding affinities were Delta>Omicron>wild in 1:1 docking with ACE2. Considering the Wild-type is non-existing nowadays, Omicron showed less ACE2 binding property. The 59Cut of spike-RBD and its mutants THR500SER/THR500GLY may be further screened as universal blocker of this virus.

Published: June 2022

Abstract
Introduction
Schatzker 3 fractures of tibial plateau are classically treated with open reduction and internal fixation. Recent mini-invasives techniques have been developed with balloon cementoplasty. Tektona® device was originally designed for vertebral kyphoplasty, and has never been described in peripheral limb reduction and fixation. The present article proposes a new technique using Tektona® flexible lamella for reduction and fixation of Schatzker 3 tibial plateau fractures.
Case Presentation
The patient was a 54-years-old female who fell from her height and sustained a direct trauma to the right knee. A closed fracture of the right lateral tibial plateau (Schatzker 3) was documented. A closed reduction was performed using Tektona® flexible lamella and cementoplasty, under fluoroscopic control. An 82% reduction of the plateau was assessed on the post-operative tomography. No per-operative complication was noted.
Conclusions
This first case of Tektona® use in tibial plateau fracture led to a satisfying result regarding the fracture reduction, with no per-operative complication. The main advantage of this technique over balloon kyphoplasty is the unidirectional and repeatable reduction maneuver. The reduction of the plateau can indeed be done without compression of the underlying cancellous bone by orienting the Tektona® lamella upwards.

Abstract
Background. Whether cigarette smoking affects the heart post-myocardial infarction (MI) in a sex-dependent way remains controversial. Using a mouse model, we investigated cardiac remodeling under the influence of acute cigarette smoke (CS) exposure following ischemic injury in both sexes. Methods. Ten cigarettes were smoked twice daily for 2 weeks followed by MI and then 1 additional week post permanent LAD ligation. Cardiac function, histology, and infarct size were assessed, and inflammatory markers quantified by RT-PCR. Statistical comparisons were performed using an unpaired t-test or ANOVA followed by Tukey post hoc test. Results. We observed that cigarette smoking exacerbated both left and right ventricular remodeling only in males at an early stage of post-MI. Females did not display a significant structural and/or functional alteration within 7 days of cardiac remodeling post-MI upon CS exposure. Worsened right ventricular remodeling in males was independent of pulmonary congestion. CS-exposed males exhibited enhanced increases in left ventricular end systolic and diastolic volumes, as well as reductions in ejection fraction and fractional area changes of left ventricular base. At day 7, infarct size was increased by cigarette smoking in males only, which was accompanied by enhanced collagen deposition in both the infarcted and peri-infarcted areas. Both IL-6 and TNF-α mRNA expression significantly increased in CS-exposed MI male group only at day 7 post-MI suggestive of prolonged inflammation. Conclusions. These findings indicate that CS exposure worsens the progression of cardiac remodeling post-MI in male sex in a significant manner compared to female sex at least at early stages.
Scalability Improvement of IEEE 802.11ah IoT Networks
Authors: Naghzali Motahareh , Kazeminia Mahdi , Mehrjoo Mehri 
Published: June 2022

Abstract
In this paper, we propose a non-orthogonal multiple access (NOMA) based grouping method for IEEE 802.11ah, a promising platform for the internet of things (IoT). The grouping method improves the scalability of IoT networks, by reducing collisions in the access points (APs). The proposed method puts those IoT devices (IoT-Ds) whose channel gains are far enough from each other, i.e., who satisfy NOMA constraints, in the same group. Therefore, using successive interference cancellation (SIC), the AP is able to decode the simultaneous signal transmissions from IoT-Ds in a group. To assign IoT-Ds into groups and determine their transmission power, we formulate a total throughput maximization problem as a joint optimal grouping and power allocation problem, which is a non-convex mixed-integer programming problem. We convert it to a convex problem using quadratic fractional programming (QFP), and then we solve it using augmented Lagrange multiplier (ALM) method. Moreover, to reduce the complexity of the solution, we propose a fast grouping method to allocate power to each group in parallel. Simulation results show that the proposed methods have outstanding performance compared to conventional association identifier (AID)-based grouping method; besides, scalability of the network in terms of throughput, power consumption and channel utilization improves dramatically because of the collision reduction of IoT-Ds, which is achieved by deploying NOMA and SIC. Furthermore, the fast grouping method decreases the computational complexity greatly at the expense of a small reduction in network performance.

Published: June 2022

Abstract
ObjectiveTo describe frequency, intensity and impact of genito-urinary syndrome of menopause (GUSM) in breast cancer (BC) survivors receiving hormonotherapy (HT).MethodsWeb-based survey hosted on the Seintinelles website (database of patients and caregivers). Specific questionnaire of 43 questions, including sociodemographic characteristics, history of BC, characteristics of HT, side effects other than GUSM, symptoms of GUSM (frequency, intensity, treatment, and impact) and overall expectations regarding treatment.ResultsAmong 1,157 participants, 96.4 % had at least one GUSM symptom. Percentages with at least one urinary, gynecological, or sexual symptom were 56.0 %, 85.6 % and 86.1 % respectively while 70.3 % and 10 % declared at least 5 and 10 symptoms respectively. Mean (SD) and median (range) numbers of symptoms were 5.9 (2.8) and 6 (0-14) respectively. Most frequently reported symptoms were decreased desire (77.8 %), decreased arousal (71.4 %), and vaginal dryness 68.4 %). On a scale from 0 (no impact) to 10 (maximal impact), the most important impact was reported for sexual life (mean: 6.6 ± 3.5) followed by psychological condition/self-image (mean 5.4 ± 3.1), and relations with partners (mean: 5.1 ± 3.4). Only 13.6 % of participants had received information on GUSM prior to the survey.ConclusionsGUSM remains underdiagnosed and underestimated in BC survivors who receive HT, although it is among most frequent and disabling side effects of HT. Awareness should be increased among physicians, along with information to women. Early detection and treatment of symptoms and prophylaxis of GUSM in at-risk women should be implemented.

Authors: Zhang Hanchen , Cao Qing 
Published: June 2022

Abstract
Physically-based distributed hydrological models are widely used to represent and study runoff and sediment in various conditions of the climatic. This paper presents work done to model runoff and sediment from a semi-arid watershed in the Loess Plateau using two models: CASC2D-SED (CASCade 2 Dimensional SEDiment) and GSSHA (Gridded Surface Subsurface Hydrologic Analysis) models. Of particular importance in this work is exploring similarities and differences in runoff and sediment molding results between the two models. The CASC2D-SED and GSSHA models calculated similar rainfall infiltration and sediment transport capacity of surface runoff. Comparison of modeled data to measured discharge and soil erosion data is made for typical flood events in 1981–2017. Both models performed well in three divided periods for runoff and sediment simulation results, with the average Nash-Sutcliffe coefficient values of 0.81 and 0.70. The GSSHA model performed better in the total and maximum of runoff and sediment, with the average relative error of peak discharge, runoff depth, and peak sediment values of 8.6%, 6.7%, and 6.6% higher, respectively. Whereas, the CASC2D-SED model performed better in the timing of runoff and sediment, with the average time difference of peak discharge and sediment values of 0.27 and 1.02 higher, respectively.
The MIDWIZE conceptual framework – A midwife-led care model that fits the Swedish health care system might after contextualization, fit others
Authors: Lindgren Helena , Erlandsson Kerstin 
Published: June 2022

Abstract
Objective: Familiarity with the unique tradition and experience of Swedish midwives during the more than 300 years in which midwife-led care has contributed to one of the lowest maternal and neonatal mortality and morbidity ratio in the world might encourage professionals in other countries to follow the Swedish example. The framework described below, reflecting the midwife’s role in the Swedish health care system, might, after implementation, strengthen maternal and neonatal outcomes if contextualized to other settings.Results: Using a four-step procedure we identified our topic, made a literature review, identified the key components and their internal relationship, and finally developed the MIDWIZE conceptual framework. In this framework, the midwives in collaboration with obstetricians, provide evidence-based care with continuous quality improvements during the whole reproductive life cycle. Teamwork including specialists for referral and a responsive, relational, trust-based practice is the foundation for provision of midwife-led care for healthy women with a normal pregnancy. The well-educated midwife, of high academic standard, promoting gender equality and equity is the hub in the team and the primary care provider.

Published: June 2022

Abstract
Purpose: Against the backdrop of the ever-increasing aging population in Sri Lanka and the scarcity of local evidence on quality of life (QoL) among rural elderly, this study was conducted to assess the QoL of the community-dwelling older adults in rural Sri Lanka.Methods: This cross-sectional study was conducted among community-dwelling older adults (60-74 years) in a selected rural setting in Sri Lanka. Statistically significant associations of QoL were determined by using the K-means cluster analysis followed by multivariable analysis.Results: The final sample consisted of 3573 community-dwelling older adults (response rate 97.8%). The mean (SD) age of the sample was 66.7 (4.3) years and the majority were females (n=2130, 59.6%). Amongst the six QoL domains assessed (physical, psychological, social, functional, environmental and spiritual domains), the highest and the lowest mean (SD) scores were reported for the functional [63.4(16.9)] and the physical [52.9(15.0)] domains respectively. Aged 70 years or more, either unmarried/widowed/divorced, lower educational levels and having chronic illnesses were statistically significant associations of QoL (p<0.05).Conclusion: The QoL among community-dwelling older adults in rural Sri Lanka is moderate. As having social support, absence of chronic diseases and good education level were found to be associated with better QoL, strengthening community-based interventions to improve these aspects is recommended.

Published: June 2022

Abstract
Background Rainbow trout is an important cool, freshwater aquaculture species used as a model for biological research. However, the genome reference has not been annotated for epigenetic markers affecting various biological processes, including muscle growth/atrophy. Increased energetic demands during gonadogenesis/reproduction provoke muscle atrophy in rainbow trout. We described DNA methylation and its associated gene expression in atrophying muscle by comparing gravid, diploid females to sterile, triploid females. Results Methyl Mini-seq and RNA-Seq were simultaneously used to characterize genome-wide DNA methylation and its association with gene expression in rainbow trout muscle. Genome-wide enrichment in the number of CpGs, accompanied by depleted methylation levels, was noticed around the gene transcription start site (TSS). Hypermethylation of CpG sites within ±1kb on both sides of TSS (promoter and gene body) was weakly/moderately associated with reduced gene expression. Conversely, hypermethylation of the CpG sites in downstream regions of the gene body +2 to +10 kb was weakly associated with increased gene expression. Unlike mammalian genomes, rainbow trout gene promotors are poor in CpG islands, at <1% compared to 60%. No signs of genome-wide, differentially methylated (DM) CpGs were observed due to the polyploidy effect; only 1,206 CpGs (0.03%) were differentially methylated, and these were primarily associated with muscle atrophy. Twenty-eight genes exhibited differential gene expression consistent with methylation levels of 31 DM CpGs. These 31 DM CpGs represent potential epigenetic markers of muscle atrophy in rainbow trout. The DM CpG-harboring genes are involved in apoptosis, epigenetic regulation, autophagy, collagen metabolism, cell membrane functions, and Homeobox proteins. Our study also identified genes explaining higher water content and modulated glycolysis previously shown as characteristic biochemical signs of rainbow trout muscle atrophy associated with sexual maturation. Conclusions This study characterized DNA methylation in the rainbow trout genome and its correlation with gene expression. This work also identified novel epigenetic markers associated with muscle atrophy in fish/lower vertebrates.

Published: June 2022

Abstract
Conventional subspace, Compressive Sensing (CS) based methods are the estimation algorithms for off-grid direction of arrival which has the dictionary mismatch problem due to limited discretization of the grid points θ ∈ [−π/2 , −π/2]. These algorithms suffer high computational complexity and excessive overhead for accurate and need lot of time snapshots for proper DOA estimation. In this paper, we used combination of a particle swarm optimization and multiple signal classification (PSO-MUSIC) algorithm for direction-of-arrival (DOA) estimation for uniform linear array (ULA). The novel PSO-MUSIC and PSO-correlation algorithms present a systematic approach for searching the spatial spectrum peak, to find the accurate target position by updating the global best particle position iteratively. The statistical performance analysis of PSO-MUSIC and PSO-correlation algorithms shows that these method has better accuracy over other DOA estimation methods with single snapshot.
