Chronic Stroke
Authors: Jung Joo Yeol , Youn Pong Sub , Kim Dong Hoon 
Published: July 2020

AbstractThis study was performed to evaluate the effects of Mirror therapy combined with
EMG-triggered Functional Electrical Stimulation on upper extremity function in
patient with Chronic Stroke. A total of 24 chronic stroke patients were divided
into 3 groups. Group I (n=8) was given with traditional physical therapy
(TPT), group II (n=7) was given with traditional physical therapy and
mirror therapy (MT), and group III (n=9) was given with traditional
physical therapy and mirror therapy in conjunction with EMG-triggered Functional
Electrical Stimulation (EMGFES-MT). Each group performed one hour a day 5 times
a week for 6 weeks.We obtained the following result between before and after treatments about
changes of elbow flexion muscle strength (EFMS), elbow extension muscle strength
(EEMS), wrist flexion muscle strength (WFMS), wrist extension muscle strength
(WEMS), elbow flexion range of motion (EFROM), elbow extension range of motion
(EEROM), wrist flexion range of motion (WFROM), wrist extension range of motion
(WEROM), grip strength (GS) and upper extremity function.Each group showed a significant difference in EFMS, EEMS, WFMS, WEMS, EFROM,
EEROM, WFROM, WEROM, GS and upper extremity function (p<0.05) EMFES-MT
group revealed significant differences in EEMS, WEROM, grip strength and upper
extremity function as compared to the other groups (p<0.05). No
difference was found in the change of spasticity among the 3 groups.Our results showed that EMFES-MT was more effective on elbow, WFMS, WEMS, AROM,
grip strength and upper extremity function in patients with chronic stroke. We
suggest that this study will be able to be used as an intervention data for
recovering upper extremity function in chronic stroke patients
Postoperative Pain Is Correlated with Scaphoid Dorsal Translation following Scapholunate Interosseous Ligament Reconstruction
Authors: Vutescu Emil S. , Wolfe Scott W. , Sung Kevin , Jethanandani Rishabh , Lee Steve K. 
Published: July 2020

AbstractBackground Dorsal scaphoid translation (DST) has been demonstrated to occur in patients with complete scapholunate interosseous ligament (SLIL) tears. Radiographs and magnetic resonance imaging (MRI) have demonstrated ability to detect DST in patients with documented complete scapholunate (SL) disruption, but the relevance of this parameter to outcomes of reconstruction has not been determined.Purpose The purpose of this article is to determine how radiographic parameters of SL dissociation correlate with postoperative pain and functional outcomes of SLIL reconstruction.Methods We performed a retrospective review of prospectively collected data on a cohort of 14 patients who underwent SLIL repair or reconstruction. Preoperative data included radiographic measurements of carpal posture and alignment (SL angle, radiolunate [RL] angle, SL gap, and DST), self-reported measure of average pain on a numerical rating scale (NRS) of 0 to 10, and the patient rated wrist evaluation (PRWE) survey. Postoperatively, the same data were collected at each follow-up visit. Radiographic parameters were statistically compared with postoperative NRS pain score and PRWE scores. Statistical correlations were calculated using Spearman's correlation coefficient, and mean NRS pain scores were compared using Wilcoxon's rank-sum tests, with an α value of p = 0.05.Results Mean NRS pain scores improved significantly after surgery. Mean DST improved significantly after surgery. The presence of postoperative dorsal scaphoid translation (DST) correlated strongly with postoperative pain. SL angle, RL angle, and SL gap showed no correlation with patient reported pain. There was no correlation with any radiographic parameter and PRWE.Conclusions Our study demonstrates that the presence of DST in postoperative radiographs has a strong correlation with patient reported pain following SLIL reconstruction. We conclude that correction of dorsal translation of the scaphoid is a more sensitive predictor of postoperative pain relief than SL gap, RL angle, or SL angle.Level of evidence This is a Level IV study.

Published: July 2020

AbstractThe combination of short stature, auditory canal atresia, mandibular hypoplasia, and skeletal abnormalities (SAMS, OMIM: 602471) has been reported as an ultra-rare, autosomal-recessive developmental disorder with unique skeletal anomalies. To the present date, only four affected individuals have been reported. There are several striking orthopaedic diagnoses within the SAMS syndrome. In particular, the scapulohumoral synostosis and the bilateral congenital ventral dislocation of the hips. The purpose of this report is to underline the importance of recognizing pathognomic features of SAMS syndrome. Whenever a bilateral congenital ventral dislocation of the hips and/or a scapulohumoral synostosis is found or clinically suspected, SAMS syndrome should be considered as the primary diagnosis until proven otherwise.

Published: July 2020

Abstract
Introduction Chronic otitis media is a widespread disease of developing countries. The burden of the disease continues to be high and so is the demand for surgical myringoplasty. This pilot study aimed to compare in adults the outcomes of myringoplasty with and without the application of epidermal growth factor gel (EGF) with respect to the time taken for graft uptake, improvement of hearing, and complications.
Materials and Methods This randomized controlled study was undertaken in a tertiary referral public hospital in a span of 2 years with a sample size of 60 patients. All of them underwent diagnostic nasal endoscopy, otoendoscopy, and pure tone audiometry and treated with conventional underlay myringoplasty using temporalis fascia (Group A—30 cases with EGF, Group B—30 controls without EGF). Patients were followed-up at 15, 30, 90 days postoperatively.
Results The average time taken for closure of tympanic perforation and graft uptake by group A was lesser than group B. This difference was found to be statistically significant. Residual perforation at 1 month was commoner in group B as compared with group A. The final improvement of the hearing was the same in both the groups in the healed cases.
Conclusion The EGF can be used to improve the outcomes of myringoplasty. It can hasten the closure of tympanic membrane perforation and increase the success rates of the surgery.

Abstract
Range verification in proton therapy is a critical quality assurance task. We studied the feasibility of online range verification based on proton-induced acoustic signals, using a bidirectional long-short-term-memory recurrent neural network and various signal processing techniques. Dose distribution of 1D pencil proton beams inside a CT image-based phantom was analytically calculated. The propagation of acoustic signal inside the phantom was modeled using the k-Wave toolbox. For signal processing, five methods were investigated: down-sampling (DS), DS + HT (Hilbert transform), Wavelet decomposition (Wavedec db1, db4 and db20). The performances were quantitatively evaluated in terms of mean absolute error, mean relative error (MRE) and the Bragg peak localization error (

Abstract

Objective. Gel aspiration-ejection (GAE) has recently been developed for the rapid production of dense, anisotropic collagen gel scaffolds with adjustable collagen fibrillar densities. In this study, a GAE system was applied to produce aligned Schwann cells within a type-1 collagen matrix to generate GAE-engineered neural tissues (GAE-EngNT) for potential nerve tissue engineering applications. Approach. The stability and mechanical properties of the constructs were investigated along with the viability, morphology and distribution of Schwann cells. Having established the methodology to construct stable robust Schwann cell-loaded engineered neural tissues using GAE (GAE-EngNTs), the potential of these constructs in supporting and guiding neuronal regeneration, was assessed both in vitro and in vivo. Main results. Dynamic mechanical analysis strain and frequency sweeps revealed that the GAE-EngNT produced via cannula gauge number 16 G (∼1.2 mm diameter) exhibited similar linear viscoelastic behaviors to rat sciatic nerves. The viability and alignment of seeded Schwann cells in GAE-EngNT were maintained over time post GAE, supporting and guiding neuronal growth in vitro with an optimal cell density of 2.0 × 106 cells ml−1. An in vivo test of the GAE-EngNTs implanted within silicone conduits to bridge a 10 mm gap in rat sciatic nerves for 4 weeks revealed that the constructs significantly promoted axonal regeneration and vascularization across the gap, as compared with the empty conduits although less effective regeneration compared with the autograft groups. Significance. Therefore, this is a promising approach for generating anisotropic and robust engineered tissue which can be used with Schwann cells for peripheral nerve repair.

Published: July 2020

Abstract
The study of gas-dynamic processes in gas-air systems of engines in order to improve the processes of gas exchange, mixture formation and combustion is an urgent task. The results of experimental studies of gas-dynamic processes in the intake system of an engine with turbo-compressor are presented in the article. A brief description of the setup and methods of experiments is presented. A spectral analysis of functions was chosen as a tool for monitoring gas-dynamic phenomena in different systems. A comparative analysis of the amplitude spectra of the pulsations of the velocity and pressure of the flows in the intake system of the engine with and without a turbo-compressor is presented in the article. The installation of a turbo-compressor leads to a significant change in the structure of gas flows in the intake system. A method for stabilizing the pulsating flow in the intake system by installing a leveling grid in the output channel of the compressor is proposed. It has been established that the presence of a leveling grid in the intake system of an engine with turbo-compressor leads to a decrease in the low-frequency amplitudes of the velocity pulsations and the pressure of the flow by up to 30%.

Development of renewable power generation in Russia: opportunities and risks from the climate perspective
Authors: Fedotova E V , Klimenko V V 
Published: July 2020

Abstract
The main trends of the renewable generation development are discussed both on the global and national scales. The climate-driven factors of renewable power development are addressed considering the climate change impact. A method of the long-term climate projection assessment is proposed. The forecast estimations of the precipitation amount and the surface wind speed are developed considering a difference between the climate scenarios. The robust output of the fulfilled analysis is a general climate tendency to some improvement of the renewable power operation conditions under all realistic climate projections. The main climate-related negative effect found is a wind speed decrease in the European part of Russia and southern West Siberia, which means that some adaptation measures should be kept in mind when planning renewable power construction in these areas.

The open source development paradigm was employed to develop a computational tool to process daily air temperature data. The computational workflow included data preprocessing, clustering procedure, as well calculation and visualization of the energy-related climate characteristics. Applicability of the developed tool was demonstrated considering an analysis of the regional features related to the heating and cooling energy demand indicators. It has been found that the considered locations have distinctively different patterns of the heating and cooling degree-days, despite of the very close values of the annual average temperatures.

Published: July 2020

Abstract
The intensity of free convection research leads to a wider understanding of the mechanisms and possibilities of using free-convection currents for the heat discharge or heatremoval in many industries, in energy processes, in a large number of devices or systems. Free convection significantly affects the maximum values of heat fluxes, and studying them becomes quite important for problems in which other methods of heat transfer are not applicable or uneconomical. The phenomena of free-convective heat transfer are quite complex, processes of conjugate heat transfer, for example, radiation and convection can be observed. Theoretical methods of description and calculation are used for bodies of simple shape: ball, plate, cylinder. The methods of theoretical analysis for heat transfer of bodies of complex shape are too voluminous and cumbersome. The intensification of free-convective heat transfer is possible through the use of various types of fins. To calculate the natural convective heat transfer of finned surfaces, the criterial dependencies of an empirical nature are mainly used. The article presents the results of a study of free-convective heat transfer of single-row horizontal bundlesof industrial bimetallic pipes with tape finning, the finning factor of 16.8. The position of the pipes in the bundle is characterized by the by transverse steps standardized for heat exchangers for air coolingS1 = 58; 61; 64; 70; 76; 86; 100 mm, to which the relative steps corresponded σ1 = S1/d = 1.208; 1.271; 1.333; 1.458; 1.583; 1.792; 2.083. An equation for calculating the free-convection heat transfer, taking into account the influence of the relative step in the range of Rayleigh number from 30,000 to 350,000 with an average deviation of ± 6.6%, has been obtained.
