Obesity is a global social and economic problem. The bariatric surgery is a most effective treatment for obesity. The presented clinical case demonstrates the usage of principles of enchanced perioperative rehabilitation for the preoperative preparation of a patient with super obesity and with severe obstructive sleep apnea and alveolar hypoventilation syndrome.A 54-year-old patient was hospitalized with complaints of obesity, impossibility of persistent weight loss conservatively, severe daytime sleepiness, frequent nocturnal awakenings (up to 8 times per night). The patient’s weight was 230 kg with a height of 157 cm (BMI 93.5 kg / m2). The examination revealed a syndrome of sleep apnea of mixed genesis of extremely severe degree, chronic night hypoxemia of an extremely severe degree. Preoperative preparation was performed in accordance with the program of enchanced perioperative rehabilitation. The duration of preoperative preparation was 19 days; weight loss — 40 kg (%WL -17,4), compensation of comorbidities was achieved as well. After that the patient underwent a laparoscopic sleeve gastrectomy. There were no complications in the postoperative period. Length of postoperative hospital stay was 6 days. At follow-up examination one year after surgery, body weight dropped from 230 to 153 kg (% WL-33.5), a significant improvement of the quality of life was achieved.The enchanced perioperative rehabilitation program can be successfully used as an effective method for preoperartive preparation of the patients with morbid obesity in combination with severe obstructive sleep apnea syndrome.and obesity hypoventilation. It can be a reasonable alternative to the standard program with preoperative intragastric balloon treatment. The use of this technique allows to increase the effectiveness of treatment of these high-risk patients, as well as to reduce the risk of perioperative complications.

Published: February 2022

BACKGROUND: The problem of diagnosis, treatment and prevention of fat liver disease (FLD) is one of the actual problems of modern medicine. In this regard, the need for the creation of reliable experimental models of the FLD, which would be as close as possible to the pathogenetic patterns of the development of this disease in humans.AIM: To create an experimental model of FLD and compare the efficiency of its reproduction in rats of different ages.MATERIALS AND METHODS: The study was conducted on male Wistar rats, whose ages at the beginning of the experiment were 3 and 18 months. Control animals were fed a standard diet. The experimental rats were kept on a diet with excess fat (45 %) and carbohydrates (31 %) for 12 weeks. The liver tissue samples were taken for morphological studies of FLD. Histological preparations were made according to the standard technique. Morphometry on digital images of micropreparations was conducted using the computer program «IMAGE J». The concentration of lipids, cholesterol, and triglecerides in the liver tissue was determined, and the concentration of ALT in the blood serum was determined. To assess the biophysical properties of the liver tissue, the method of multifrequency bioimpedance measurement was used.RESULTS: The transfer of animals to a high-calorie diet developed by us led to the development of FLD. This was evidenced by an increase of the liver mass, its pale shade and soft consistency. Morphometric signs of FLD were also revealed. Hypertrophy of hepatocytes was observed with a simultaneous decrease in the nuclear-cytoplasmic ratio; accumulation of numerous lipid inclusions in the cytoplasm and the appearance of large lipid droplets replacing the voids of dead hepatocytes. The number of binuclear hepatocytes and nucleolus in the nucleus, the relative area of the sinusoid network were decreased. An increase in the concentration of lipids, cholesterol and triglecerides in the liver tissue of experimental rats, as well as the activity of ALT in the blood serum, was observed. Changes in the bioimpedance measurements of the liver tissue also indicated the development of severe fatty degeneration of the liver in both young (to a greater extent) and old rats.CONCLUSION: The model of FLD we have advanced based on a combined (fat-carbohydrate) high-calorie diet. It leads to the development of pronounced morphological, biochemical and biophysical signs of this pathology in all experimental rats. The most pronounced manifestations of FLD are observed in young animals.

Authors: Pigarova E. A. , Dzeranova L. K. 
Published: February 2022

BACKGROUND: Vitamin D deficiency and insufficiency are widespread medical abnormalities, but their frequency in endocrine diseases has generally not been studied.AIM: To provide a comparative assessment of vitamin D levels in patients with diabetes mellitus type 2, primary hyperparathyroidism (PHPT), central hypercortisolism (Cushing’s disease; CD) and acromegaly.MATERIALS AND METHODS: Total 25(OH)D was determined using the immunochemiluminescent method (the laboratory participates in the DEQAS program). All patients had GFR > 60 ml/min, no history of use of vitamin D supplementation within previous month.RESULTS: The study included 365 patients who, after applying the inclusion/exclusion criteria, were divided into 5 main research groups: 33 patients with diabetes mellitus type 2, 23 patients with PHPT, 68 patients with CD, 22 patients with acromegaly, and 141 apparently healthy patients. Significantly low levels of vitamin D were found in patients with diabetes mellitus type 2 (14.8 ng/ml), acromegaly (14.9 ng/ml), CD (14.6 ng/ml), and PHPT (15.9 ng/ml) compared with a group of otherwise healthy patients (18.8 ng/ml).CONCLUSION: The results of the study demonstrate a high prevalence of vitamin D deficiency not only in groups of patients with chronic diseases, but also among practically healthy patients. Further studies are needed to address the causes of high vitamin D deficiency in the described endocrine diseases.

Effect of omega-3 fatty acids on the telomere length: A mini meta-analysis of clinical trials
Authors: Ali Sawan , Scapagnini Giovanni , Davinelli Sergio 
Published: February 2022

Abstract
Telomeres are protective caps at the end of eukaryotic chromosomes, whose length is correlated with health and lifespan. Telomere attrition is a common feature of the aging process and can be accelerated by oxidative stress and chronic inflammation. Various nutrients influence the telomere length, partially due to their antioxidant and anti-inflammatory properties. The aim of this review was to meta-analytically assess the effect of omega-3 fatty acids on the telomere length. We searched four databases (PubMed, Web of Sciences, Scopus, and the Cochrane Library) from inception until November 2021. Of 573 records, a total of 5 clinical trials were included for the quantitative meta-analysis, comprising a total of 337 participants. The results revealed an overall beneficial effect of omega-3 fatty acids on the telomere length (mean difference = 0.16; 95% CI, 0.02, 0.30; p = 0.02). Despite a limited number of studies, the available evidence suggests that omega-3 fatty acids may positively affect the telomere length. However, larger clinical trials are needed to confirm our findings, along with studies aimed to clarify the underlying molecular mechanisms.
An ROI-based robust video steganography technique using SVD in wavelet domain
Authors: Pilania Urmila , Tanwar Rohit , Gupta Prinima 
Published: February 2022

Abstract
Steganography is a technique that embeds secret information in a suitable cover file such as text, image, audio, and video in such a manner that secret information remains invisible to the outside world. The study of the literature relevant to video steganography reveals that a tradeoff exists in attaining the acceptable values of various evaluation parameters such as a higher capacity usually results in lesser robustness or imperceptibility. In this article, we propose a technique that achieves high capacity along with required robustness. The embedding capacity is increased using singular value decomposition compression. To achieve the desired robustness, we constrain the embedding of the secret message in the region of interest in the cover video file. In this manner, we also succeed in maintaining the required imperceptibility. We prefer Haar-based lifting scheme in the wavelet domain for embedding the information because of its intrinsic benefits. We have implemented our suggested technique using MATLAB. The analysis of results on the prespecified parameters of the steganography justifies the effectiveness of the proposed technique.

Abstract

Objectives
The aim of this study was to investigate differences in academic achievement between two groups of students who were taught the same course online within the nursing program but through two different teaching strategies and to examine the students’ attitudes towards flipped classroom.

Methods
Online lectures using Zoom was given to teach a course regarding the immune system and another course was taught the same subject in flipped classroom approach using video lectures followed by seminars. Academic achievement were compared between the groups, and perspectives on flipped classroom were investigated using a questionnaire.

Results
The main findings were that participation in flipped classroom seminars had a positive effect on academic achievement (OR 2.3 (CI [1.001–5.1]), and that students preferred the flipped classroom approach over traditional lectures.

Conclusions
This study suggests that a student centered teaching strategy like flipped classroom is an effective way to increase the students’ engagement and academic achievements.
Stress-strain characteristics and service life of conventional and asphaltic underlayment track under heavy load Babaranjang trains traffic
Authors: Setiawan Dian M. 
Published: February 2022

Abstract
A more durable rail track structure is fundamental in the railway industry, allowing the government to operate the train with higher speed and axle load. That means more passengers and better quality of railroads travel, thereby reducing the maintenance costs and ensuring passengers’ comfort and safety. The effect of a sub-ballast and asphalt layer thickness and freight train traffic with low operational speed on mechanical behavior and design life of conventional track and asphaltic underlayment track, are presented in this paper. One of the significant findings to emerge from this study is that an AC layer with minimum thickness of 0.20 m is required in the asphalt underlayment track application for Indonesian railway infrastructure to facilitate Babaranjang freight trains with up to 50% more tonnage. The evidence from this study also suggests that the asphalt underlayment track with 0.20 m thick of AC layer that contains grade PG70-28 binder could be beneficial to be applied in Indonesian railway system so that the rail track could be constructed with less volume of works than the regular Indonesia's conventional track with 0.40 m of sub-ballast layer.
Kantian vs. Platonic: The Ambiguity of Schopenhauer’s Notion of Ideas Explained via Its Origins
Authors: Sattar Alexander 
Published: February 2022

Abstract
The ‘Platonic Ideas’ in Schopenhauer’s metaphysics are (merely) appearances. On the other hand, as the immediate objecthood of the will, they are the essences of species and the only object of true aesthetic cognition, which leads beyond mere appearance. To explain this apparent incongruence, I offer an analysis of Schopenhauer’s early metaphysics (1809–1814), and its transformation into the metaphysics of will, fleshing out the several and divergent concepts of (Platonic) ‘idea’. Specifically, first, as part of his religious and neo-Platonic early philosophy; second, in the context of his ‘true criticism’ in the spirit of Kantian transcendental philosophy; third, as identical to the thing in itself as part of the metaphysics of will, heavily influenced by Kant’s notion(s) of ideas from CR and CJ. Explaining Schopenhauer’s mature notion of Platonic Ideas genetically as a set of homonymic notions helps us better explain its divergent meanings in WWR.

Authors: Li Rui , Song Yueqiang 
Published: February 2022

AbstractIn the present work, we are concerned with the multiple solutions for quasilinear Choquard equation with critical nonlinearity inRN{{\mathbb{R}}}^{N}. We show multiplicity results for this problem, which are characterized, respectively, by the new version of symmetric mountain-pass theorem and the mountain-pass theorem for even functionals. The novelty of our work is the appearance of the convolution terms as well as critical nonlinearities.

-order matrix, which is not suitable for generalizing Cauchy integral formula of matrix functions to its higher-order derivative form. In this paper, a new kind of derivative of matrix functions is defined, and the higher-order derivative form of Cauchy integral formula of matrix functions is also proved to be true under the new kind of definition of derivative. At the same time, some examples about calculating the values of matrix functions by using Cauchy integral formula of matrix functions and its higher-order derivative form are given.

Published: February 2022

Abstract
The coupling of metal oxide nanoparticles and electrochemically active polymers has been considered as an effective way to improve the lithium storage performance of individual electrode materials. This work reports an electrospinning process followed by thermal annealing to produce composite nanofibers of cyclized-polyacrylonitrile (cPAN) containing Co3O4 nanoparticles (cPAN/Co3O4). The as-prepared cPAN/Co3O4 nanofiber exhibits a porous nanostructure with an average diameter of 85 nm. When used for lithium-ion battery, the cPAN/Co3O4 anode delivers a reversible specific capacity as high as 997.6 mA h g−1 at 0.1 A g−1, and still maintains 396.5 mA h g−1 at 1.0 A g−1. Meanwhile, the cPAN/Co3O4 anode shows good cycling stability with a retention of 81% capacity after running 50 cycles at 0.1 A g−1. The electrochemical performance of cPAN/Co3O4 significantly outperforms its individual counterparts of cPAN and Co3O4.
Attentional Structure and Phenomenal Unity
Authors: Wiese Wanja 
Published: February 2022

Abstract
Some authors argue that phenomenal unity can be grounded in the attentional structure of consciousness, which endows conscious states with at least a foreground and a background. Accordingly, the phenomenal character of part of a conscious state comprises a content aspect (e.g., hearing music) and a structural aspect (e.g., being in the background). This view presents the concern that such a structure does not bring about phenomenal unity, but phenomenal segregation, since the background is separated from the foreground. I argue that attention can still lead to a form of phenomenal unity that connects the foreground with the background. Experiencing oneself as controlling the focus of attention can, at least occasionally, bring about an experienced connection between the attentional foreground and the attentional background of a conscious experience.

, a = 1074.23(8) pm, Z = 4). Each Tl+ cation is coordinated by four icosahedral [B12H12]2– anions (d(B–B) = 180–181 pm) providing a twelvefold coordination sphere of hydrogen atoms (d(Tl–H) = 296 pm). Tl2[B10H10] crystallizes monoclinically in the space group P21/n with a = 704.03(5), b = 1111.45(8), c = 1281.16(9) pm and β = 94.912(3)° for Z = 4. The bicapped square antiprismatic [B10H10]2– anions (d(B–B) = 147–176 pm to the two apical boron atoms, d(B–B) = 161–199 pm within the corpus) again form distorted tetrahedra around the (Tl1)+, but square pyramids around the (Tl2)+ cations. Thus (Tl1)+ is coordinated by 12 hydrogen atoms (d(Tl1–H) = 275–315 pm), but (Tl2)+ only by 11 of them (d(Tl2–H) = 267–357 pm). Both compounds show a greenish-yellow photoluminescence caused by an interconfigurational 6sp
