Authors:   School № 16 named after I. A. Lapenkov, Chernova Natalia Yu. , Romm Tatiana A. ,   Novosibirsk State Pedagogical University
Published: September 2022

Problem and Purpose. Attention to the issues of education, which are in the center of public and professional attention, creates opportunities for the school for self-realization and disclosure of its educational potential, based on the system processes of development of the educational system through the events. The problem of organization of the educational process and its management is actualized by the conditions of a changing reality. The purpose of the article is to present the experience of transforming the educational system of the school, taking into account the possibilities and limitations of today’s reality. The study was based on a set of methodological approaches of scientific school L. I. Novikova (system, synergetic), the idea of educational space (N. L. Selivanova), the concept of social education in the process of socialization (A. V. Mudrik, T. A. Romm), phenomenological approach in pedagogy (I. D. Demakova, M. V. Voropaev). The leading research methods are systematization, specification, interpretation of certain provisions, experimental work. In the process of analyzing the experience of transforming the educational system of the school, existing effective practices of education were identified, the staff and infrastructural conditions that contributed to their formation were specified, and resources for further development were identified. The conclusion is made about the need to create and develop a transformable educational space as a valuable and semantic unity of all subjects on the basis of event and phenomenological approaches. Effective management of the development of the educational system in a changing reality is possible through matrices and various variations of vertical structures in the school management structure.

Authors: Gao Xueying , Peng Lincai , Li Hui , Chen Keli
Published: September 2022

To avoid undesired polymerization and maximize the selectivity of alkyl levulinate from the acid-catalyzed conversion of biomass-derived furfuryl alcohol, the effects of catalyst and reaction parameters on the formations of humin and alkyl levulinate were investigated. The results show that Amberlyst 15, of moderate acidic strength, was more favorable for the selective conversion of furfuryl alcohol to alkyl levulinate, and heteropolyacids of strong acidic strength tended to promote furfuryl alcohol polymerization. Compared with water as a reaction medium, alcohol significantly lowered humin formation and enhanced the yield of the resulting products. The formations of humin and alkyl levulinate were both favored at high catalyst loadings and reaction temperatures. An augmentation in initial furfuryl alcohol concentration caused an increase in humin formation and a decrease in alkyl levulinate yield. A high alkyl levulinate yield of up to 94% (100% furfuryl alcohol conversion) was achieved at 110 °C for 4 h with 5 g/L Amberlyst 15 catalyst and an initial furfuryl alcohol concentration of 0.1 mol/L. At this point, about 5% furfuryl alcohol was polymerized to form the humin, and its polymerization occurred mainly during the initial reaction stage.

Published: September 2022

The process of cooking with solid alkali is a novel and efficient technology. In the present work, milled wood lignin (MWL) and water-soluble milled wood lignin (WMWL) were used as the raw materials to research their properties when cooking with MgO and active oxygen. Before and after cooking, the lignin content of the samples was estimated using attenuated total reflectance-Fourier transform infrared spectroscopy (ATR-FTIR), heteronuclear single-quantum coherence-nuclear magnetic resonance (HSQC-NMR), and gel permeation chromatography (GPC). The results showed that the properties of the MWL and WMWL were different. The G unit and A′structure in WMWL were more easily degraded than that in the MWL, where the G unit could be oxidized into a novel G′ unit. The D structure in the MWL with a weak signal could be thoroughly degraded, and the P structure was only present in WMWL and could be generated during the cooking process.
China’s new regulations on waste paper importing and their impacts on global waste paper recycling and the papermaking industry in China
Authors: Chen Zicheng , Yue Xiaopeng , He Zhibin , Zhang Lanhe
Published: September 2022

China is the largest waste paper importing market in the world. Due to more and more demands and awareness of environment/ safety issues, in recent years the Chinese government has implemented a number of new regulations on waste paper importing, for example, prohibiting importing of unsorted waste paper and lowering the foreign (non-paper) content in the imported waste paper from 1.5% to 0.5%. Small-scale (less than 50,000 tons per year capacity) paper mills are not eligible for importing waste paper. These new regulations have had profound impacts on the global waste paper recycling practice and the papermaking industry in China. At the same time, these new regulations bring up new challenges to the global waste paper recycling practices, such as increased labor costs and decreased recycling efficiency.

Published: September 2022

Agricultural waste of corn straw pulp was successfully prepared into fibers using a tetrabutylammonium acetate (TBAA) and dimethyl sulfoxide (DMSO) solvent system via a dry-jet wet spinning process at 35 °C. The dissolving process of cellulose in TBAA/DMSO was observed through a polarization microscope, and the rheological behavior of the cellulose/ TBAA/DMSO solution was also studied. The crystalline and microstructure of the regenerated cellulose fibers prepared from corn straw were investigated by Fourier transform infrared spectroscopy (FT-IR) and X-ray diffraction (XRD). In addition, the morphology was characterized with a scanning electron microscope (SEM). The thermal stability of corn straw pulp and the regenerated cellulose was also explored. Due to the presence of residual lignin, a longer time was needed for the complete dissolution of corn straw compared with pure wood pulp. In addition, the degree of polymerization and the elongation-at-break of the regenerated fiber had a small amount of attenuation. Despite the deficiencies, a good spinnability of corn straw cellulose solution could still be achieved. Fibers with a round and compact structure as well as a smooth surface were obtained.

Published: September 2022

The aim of this study was to convert the spent liquors obtained from acidic sulfite and neutral sulfite semi-chemical (NSSC) pulping processes into protein-rich fungal biomass. Three filamentous fungi, Aspergillus oryzae, Mucor indicus, and Rhizopus oryzae, were cultivated on the diluted spent liquors in an airlift bioreactor with airflow of 0.85 vvm at 35 °C and pH 5.5. Maximum values of 10.17 g, 6.14 g, and 5.47 g of biomass per liter of spent liquor were achieved in the cultivation of A. oryzae, M. indicus, and R. oryzae on the spent sulfite liquor (SSL) diluted to 60%, respectively, while A. oryzae cultivation on the spent NSSC liquor (SNL) diluted to 50% resulted in the production of 3.27 g biomass per liter SNL. The fungal biomasses contained 407 g to 477 g of protein, 31 g to 114 g of fat, 56 g to 89 g of ash, and 297 g to 384 g of alkali-insoluble material (AIM) per kg of dry biomass. The amino acids, fatty acids, and mineral elements composition of the fungal biomasses corresponded to the composition of commercial protein sources especially soybean meal. Among the fungi examined, A. oryzae showed better performance to produce protein-rich fungal biomass during cultivation in the spent liquors.

Published: September 2022

Obesity is a systemic disease and represents one of the leading causes of death worldwide by constitutingthe main risk factor for a series of non-communicable diseases such as type 2 diabetes mellitus (T2DM),cardiovascular diseases and dyslipidemia. Lifestyle interventions have been attempting to prevent T2DM andobesity but are difficult to maintain by most patients. However, the recent focus on the intestinal microbiotaand its important role in the host’s metabolism provides a new key for improving metabolic health. Modulatingthe composition of the gut microbiota was proposed as a method to manage these metabolic diseases andmost frequently this is undertaken by using probiotics, prebiotics or synbiotics. Furthermore, the action ofmetformin, the most commonly prescribed drug for treating T2DM, is mediated in part by the gut microbiota,although this interplay may also be responsible for the frequent gastrointestinal adverse effects of metformin.Thus, adding a gut microbiota modulator (GMM), such as probiotics or prebiotics, to metformin therapy couldamplify its anti-diabetic effects, while decreasing its adverse reactions. This review summarizes the varioustherapies that are used to shift the composition of the microbiome and their efficacy in alleviating metabolicparameters, it assesses the interaction between metformin and the gut microbiota, and it evaluates the existingclinical and preclinical studies that analyze the potential synergy of a combined metformin-GMM therapy.

Published: September 2022

Aims: To compare the efficacy, safety, and survival outcomes of hepatic arterial infusion chemotherapy (HAIC) versus transarterial chemoembolization (TACE) for the treatment of advanced hepatocellular carcinoma (HCC), a comprehensive meta-analysis was conducted.

Methods: MEDLINE, PubMed, Web of Science, Embase, and the Cochrane Central Register of Controlled Trials were searched from January 1966 to 20 February 2022, and relevant articles were retrieved. The literature search, quality assessment, and data extraction were conducted independently by two reviewers. The primary endpoints were objective response rate (ORR) and overall survival (OS), while the secondary endpoints were disease control rate (DCR), progression-free survival (PFS), and adverse events. The odd ratios (OR) and hazard ratios (HR) with 95% confidence intervals (95%CI) were pooled.

Results: Seven studies with a total of 989 patients were included in this meta-analysis. The pooled results showed that HAIC significantly improved ORR (OR=4.94, 95%CI: 3.47-7.05, p<0.001) and DCR (OR=2.97, 95%CI: 2.16-4.08, p<0.001). In addition, HCC patients who received HAIC had significantly longer PFS (HR=0.54, 95%CI: 0.45-0.65, p<0.001) and OS (HR=0.55, 95%CI: 0.46-0.66, p<0.001) than those who underwent TACE. Compared with TACE, HAIC showed a lower incidence for grade 3-4 adverse events (OR=0.52, 95%CI: 0.30-0.88, p<0.001).

Conclusions: HAIC may significantly improve survival benefits and exhibit higher local treatment responses with mild side effects in patients with advanced HCC compared to TACE.

Published: September 2022

Background and Aims: Validated questionnaires help to minimize diagnostic bias, to standardize symptom assessment and to achieve comparability between studies and centers. In a recent European guideline the adult and the pediatric carbohydrate perception questionnaires (aCPQ and pCPQ), were recommended to be used for the diagnosis of carbohydrate intolerances in adult and pediatric patients. The implementation of this guideline into clinical practice makes availability of validated translations a necessity.

Methods: Clinical experts who recognized the need for these questionnaires to be available in their own language participated in the translation process. The tasks were assigned and a workflow following a predefined procedure based on recommendations of the Rome foundation was developed. The procedure had 5 phases: foundation, nomination, translation, revision, cognitive debriefing. Results: Within eight months the aCPQ was translated into Bulgarian, French, Hungarian, Italian, Polish, Romanian, Russian and Slovenian language and the pCPQ into Dutch, French and Romanian. This expands the population which can be served with the aCPQ from 160 million to over 500 million Europeans. The reach of pCPQ expanded from 92 million to 193 million Europeans.

Conclusions: We report the development and implementation of a centrally organized process of translation of validated questionnaires, following a predefined procedure based on recommendations of the Rome foundation. This structured procedure may aid future efforts to standardize and harmonize the translation of validated questionnaires.

A series of polymeric composites based on polyurethanes with copolymer fragments of poly(vinyl butyral-vinyl acetate-vinyl alcohol) and 1,6-hexamethylenediamine filled with modified precipitated silica were synthesized. The content of silver in the nanocomposites was 0.1–0.2 and of copper – 0.14 and 0.2 mmol per 1 g of SiO2 (02AgCu; AgCu and 01Ag samples). The content of silver-containing silica filler in the polymer composites was 0.1, 0.5 and 1.0 wt. %. By means of the IR spectroscopy, it has been found that a physical immobilization of modified silica in the polymeric matrix takes place due to the presence of intermolecular hydrogen bonds. The influence of fillers on the structure and properties of polymer materials, in particular, on thermophysical properties and physico-mechanical parameters (tensile strength and relative elongation at rupture), were investigated. The results of physico-mechanical tests indicate that the strength characteristics of polyurethane depend on the content and concentration of fillers. It has been found that the polymeric sample filled with 02AgCu nanocomposite (0.2 mmol of Ag and Cu per 1 g of SiO2) has the highest strength of the rupture. It has been shown that the introduction of modified silica leads to a reduction of relative elongation at rupture of polymeric nanocomposite. The highest values showed the sample filled with AgCu (0.1 and 0.12 mmol Ag and Cu, respectively, per 1 g of SiO2). The introduction of silver-containing silica nanocomposites into a polyurethane, containing polyvinylbutiral copolymer fragments, leads to an increase in tensile strength and reduction of relative elongation at rupture. Polymeric composite with 0.5 wt. % of filler had the highest values of physico-mechanical parameters. It has been shown that the thermosphysical characteristics depend on the concentration and composition of the fillers and have a nonlinear character. The synthesized nanocomposites can be effectively used as biomedical materials.

A brief literature review proves that nanosized fluorescent carbon materials are widely used. In particular, they are promising in biomedicine (due to biocompatibility – for example, for biovisualization); optoelectronics; as chemical fluorescent sensors for measuring the concentration of metals, pH, anions, organic substances and biomolecules; as markers for fingerprinting. This paper investigates carbon materials obtained by oxidation of activated carbon, which are similar in their optical characteristics to carbon nanotubes. The aim of this work was the synthesis of nanocarbon material from available chemical raw materials. As a prototype, the synthesis is based on the method of obtaining carbon weakly acid cation-exchange resin. The nanocarbon material is easily dispersed in water, forming stable colloidal solutions that exhibit luminescence in the blue-green region of the visible spectrum. According to the results of thermogravimetric analysis, the thermal destruction of surface functional groups was found. The nature of the functional groups on the surface of the carbon nanomaterial was based on the obtained data of infrared spectra. The purity of the samples was monitored by X-ray diffraction analysis of the powder. For the pure sample, only the amorphous carbon spectrum was observed, and for the crude, NaCl reflexes were observed. In the region of MALDI positive ions, clusters of molecular mass have been obtained, which may belong to fullerene-like carbon structures. We believe that the high signal intensity at m/z 44 indicates a significant number of carboxyl groups. For aqueous solutions, the luminescence spectrum was measured, on which blue-green fluorescence was observed. Excitation by radiation with a wavelength was chosen based on the results of preliminary measurements of the dependence of the emission intensity on the length of the excitatory radiation. The fluorescence spectrum shows a wide maximum at 450 nm, which is slightly shifted to the long-wavelength region after centrifugation of the sample and precipitation of large fractions. The method of dynamic light scattering shows that particles with a wide range of sizes are present in the solution, the maximum distribution occurs in relatively large units.
La sociedad matrilineal asante: género, poder y representaciones sociales
Authors: Arboleda Nayibe , Arbeláez Verónica
Published: September 2022

Este artículo pretende mostrar las lógicas de poder en la estructura matrilineal asante y sus transformaciones sociopolíticas, una vez se impusieron nuevas representaciones sociales asociadas al género tras la colonización y la fundación del Estado moderno. Para el desarrollo del artículo, se utilizó el método cualitativo bajo una revisión bibliográfica de fuentes secundarias, haciendo énfasis en un análisis sobre las teorías del poder, del género y de la representación social. Igualmente, se trabajó en una revisión histórica que evidencia las transformaciones sociopolíticas, partiendo de la época pre-colonial y poscolonial (con la fundación del Estado moderno) de los rituales de las ohemaa (reina madre) y la composición matrilineal asante.
La sociedad matrilineal asante es una estructura sociopolítica que hace parte de la etnia akan en Ghana desde antes de la colonización británica. Su origen yace en la aparición de tres deidades femeninas que descendieron de los cielos con tres taburetes, simbolizando cada una de las castas familiares. La matrilinealidad, que significa que la autoridad y el poder se hereda a través de la línea materna, evoca el poder simbólico y literal de la ohemaa que le da vida a la etnia, es decir, que da a luz las nuevas generaciones de gobernantes dentro de los asante. Sin embargo, tras la colonización y luego con la fundación del Estado moderno, se impusieron desde Occidente nuevas representaciones asociadas al género que terminaron transformado la idea de poder y, por lo tanto, su función social. Es así como se redefinió el concepto de las ohemaa y su poder ha quedado marginado a la representación exclusiva de las mujeres, quienes deben encargarse de las labores del cuidado y de lo doméstico, haciendo una transición del poder en la esfera de lo público a lo privado.

Authors: Kim Hyojin , Kim Changsun
Published: September 2022

PURPOSE: The purpose of this study was to investigate the effects of 8 weeks of mat Pilates exercise on back pain, muscle mass, isokinetic muscle function, and core stability in healthy college female.METHODS: Twenty healthy college females (aged 21.7±2.5 years) were recruited for the study. The participants were divided into two groups: mat Pilates exercise group (MP, n=10) and non-Pilates control group (CON, n=10). The MP group participated in the mat Pilates exercise program for 60 minutes a day, 3 days per week for 8 weeks. Back pain and basal physical fitness were assessed before and after the experimental period. Left and right core stabilities at 0°, 45°, 90°, 135°, and 180° were measured using Centaur (BFMC, Germany). Isokinetic muscle function (60°/s) of both the knee and trunk was also measured using the isokinetic dynamometer Cybex.RESULTS: After mat Pilates exercise for 8 weeks, there was a significant interaction between the MP and CON groups in back pain during daily activity and lower back stiffness (p<.05), respectively. There was also a significant interaction between the two groups in the left and right core stability at 45°, 90°, 135°, and 180° (p<.05, p<.01, p<.001), respectively. Additionally, there was a significant interaction between the two groups in the right knee and left knee isokinetic extensor muscle strength (p<.05, p<.001, respectively). However, there was no significant interaction between the two groups in trunk isokinetic extensor and flexor muscle strength (NS). There were no significant interactions between two groups in the muscle mass of total body, trunk, and legs (NS), respectively. Regarding basic physical fitness, there were significant interaction effects between the two groups in cardiovascular fitness, sagittal reach, and sit-ups (p<.05).CONCLUSIONS: These results suggest that continued mat Pilates exercise can improve back pain and core stability with enhancement of leg isokinetic muscle strength independent of the muscle mass of the total body, trunk, and legs.
Therapeutic Sources of Skeletal Muscle Regeneration from Volumetric Muscle Loss: A Narrative Review
Authors: Lee Kwangjun , Park Wonil , Hong Kwang-Seok
Published: September 2022

PURPOSE: Minor skeletal muscle injuries can be repaired, but more extensive volumetric muscle loss (VML) leads to a permanent functional disability with ambiguous therapeutic outcomes, and reconstructive surgical procedures are constrained by donor tissue scarcity. This review assessed the considerable attention paid to biomaterials in healing damaged skeletal muscle.METHODS: A comprehensive search in PubMed, Web of Science, Google Scholar, and Wiley Online Library was conducted to obtain previous studies exploring the state of biocompatible tissue scaffolds for VML recovery.RESULTS: By regenerating the function of damaged skeletal muscle, tissue-engineered skeletal muscle construction could revolutionize the treatment of VML. However, transporting cells into the wounded muscle location presents a significant challenge because it may result in unfavorable immunological reactions. The development and validation of several biomaterials with varying physical and chemical natures to treat various muscle injuries have recently been undertaken to overcome this problem. This review discusses the relative benefits of satellite cells (SC), the most prevalent skeletal muscle stem cells employed to seed scaffolds.CONCLUSIONS: Biomaterials can be used with skeletal muscle stem cells and growth factors to repair VML because of their customizable and desirable physicochemical qualities. Owing to the capacity of SCs for self-renewal and their undifferentiated state, these cells are excellent candidates for cell therapy. A large gap exists between understanding SC behavior and how it can be used to repair and regenerate human skeletal muscle tissue. Thus, this review sought to portray the current knowledge on the lifespan of SCs and their involvement in exercise-induced muscle regeneration and hypertrophy.

Published: September 2022

PURPOSE: The purpose of this study was to examine the association between objectively measured physical activity and metabolic syndrome in Korean adults and older adults.METHODS: A total of 2,191 adults and older adults from the Korea National Health and Nutrition Examination Survey from 2014 to 2017 were analyzed. Participants were categorized into three groups (‘Inactive’, ‘Active’, ‘Highly active’) according to physical activity guidelines. A chi-square test was performed to confirm whether the physical activity guidelines were met according to metabolic syndrome and the difference between metabolic syndrome according to age group. Logistic regression was used to predict the relationship between physical activity and metabolic syndrome.RESULTS: The prevalence of metabolic syndrome differed according to whether physical activity guidelines were met in older adults, and the prevalence of metabolic syndrome and its risk factors varied according to age group. Compared to the Inactive group, the odds ratios (OR) for metabolic syndrome were 0.73 (95% confidence interval [CI]: 0.56-0.95) and 0.65 (95% CI: 0.47-0.88) in adults in the Active and Highly active groups, respectively; and 0.46 (95% CI: 0.28-0.78) and 0.39 (95% CI: 0.22-0.69) in older adults in the Active and Highly active groups, respectively.CONCLUSIONS: As the level of physical activity increased, the OR of having metabolic syndrome and its risk factors decreased: this relationship was stronger in older adults than in adults. Therefore, physical activity guidelines should be met to prevent and manage metabolic syndrome.

Published: September 2022

Medium-density fiberboard (MDF), a wood-based material that consists of a tight random network of wood fibers, deforms more than wood when exposed to water. For the first time, the microscopic deformations of MDF were tracked during swelling. A hygroscopic swelling setup imposing the material to deform throughout tomographic acquisition was used coupled to X-ray microtomography. An advanced reconstruction algorithm enabled reconstruction of images free of motion artefacts, and state-of-the-art digital volume correlation was applied to determine the mechanical strain fields at high resolution. Wood fiber bundles were then segmented from single fibers with deep learning using the UNet3D architecture. Combined with the strain fields, this segmentation showed that wood fiber bundles were the drivers of MDF swelling. This contrasts with the hygroscopic behavior of wood, where structured wood swells less than single fibers, which might be caused by a difference in penetration and distribution of the adhesive, in and on the wood fiber cell wall. The unique characterization of MDF’s dynamic behavior can already be used to develop manufacturing strategies to improve water resistance, therefore widening the uses of natural fiber-based materials.
China se lang, onvoltooide twintigste eeu en die moontlike gevolge wat dit vir Afrika inhou
Authors: Lötter C
Published: September 2022

In hierdie bydrae word ondersoek ingestel na die ongeewenaarde ekonomiese vooruitgang en gepaardgaande grootmoondheidambisies van China. In die besonder word gevra wat die moontlike gevolge van hierdie epogverskuiwende ontwikkeling vir die vasteland van Afrika sou wees. China se strewe na grootmoondheidstatus in die 21ste eeu word gewoonlik aan die hand van of realisme of idealisme verduidelik, maar ek wil graag daarna kyk vanuit 'n geskiedkundige invalshoek, wat blyk 'n unieke oogpunt te wees. Ek ondersoek die invloed wat die houvas van 'n geskiedkundige gesindheid op die Chinese psige het in hul naarstige soektog na grootmoondheidstatus. Die sogenaamde "Chinese Droom" offuqiang ("welvaart en mag") word gerugsteun deur die retoriek van die "honderd jaar van vernedering" (18421949). Daar is egter ook ander faktore wat 'n bydrae lewer tot die vermoede dat beweegredes eie aan die twintigste eeu die aansporing mag wees tot die ongekende industriele, militere en ekonomiese groei in China. My gekose metodologie is die poststrukturalisme, wat my in staat stel om met vrug benaderings in ag te neem wat selfs teenstrydig met mekaar is. Ek kom tot die gevolgtrekking dat China se rol in Afrika se welvaart van die 21ste eeu genuanseerd is. Nie net is daar talle rolspelers (soos Rusland en die Verenigde State) wat 'n belang by Afrika het nie, maar Afrika is vanuit 'n Chinese oogpunt maar van geringe belang. Die Chinese invloed op Afrika blyk grotendeels voordelig vir die vasteland te wees, maar daar moet ook gelet word op die beperkings wat China se geneigdheid tot outokrasie het op die land se ontwikkelingsvooruitsigte.
CenterYou: Android privacy made easier the Cloud Way

Published: September 2022

The Smartphone industry has expanded significantly over the last few years. According to the available data, each year, a marked increase in the number of devices in use is observed. Most consumers opt for Smartphones due to the extensive number of software applications that can be downloaded on their devices, thus increasing their functionality. However, this growing trend of application installation brings an issue of user protection, as most applications seek permissions to access data on a user’s device. The risks this poses to sensitive data are real to both corporate and individual users. While Android has grown in popularity, this trend has not been followed by the efforts to increase the security of its users. This is a well-known set of problems, and prior solutions have approached it from the ground up; that is, they have focused on implementing reasonable security policies within Android’s open-source kernel. While these solutions have achieved the goals of improving Android with such security policies, they are severely hampered by the way in which they have been implemented them. In this work, a framework referred to as CenterYou is proposed to overcome these issues. It applies pseudo data technique and cloud-based decision-making system to scan and protect Smartphone devices from unnecessarily requested permissions by installed applications and identifies potential privacy leakages. The current paper demonstrated all aspects of the CenterYou application technical design. The work presented here provides a significant contribution to the field, as the technique based on pseudo data is used in the actual permissions administration of Android applications. Moreover, this system is user and cloud-driven, rather than being governed by over-privileged applications.

An electronic search for publications on the features of the course of COVID-19 in patients with the most common chronic noncommunicable diseases (arterial hypertension, diabetes mellitus and obesity) was carried out using the Scopus, Web of Science, MedLine, The Cochrane Library, EMBASE, Global Health, CyberLeninka databases, RSCI, as well as journals peer-reviewed by the Higher Attestation Commission. The review analyzed the effect of comorbidity on the prognosis of a new coronavirus infection (complication rate, severity of the course, mortality). It has been shown that previous noncommunicable diseases are a significant risk factor for adverse outcomes in patients with COVID-19, and if the effect of arterial hypertension is not confirmed by all authors, then type 2 diabetes mellitus, as well as any degree of obesity, are important prognostic signs of an unfavorable course of the new coronavirus infections.
Thus, in the context of the COVID-19 pandemic, patients suffering from chronic noncommunicable diseases need more careful monitoring and preventive measures aimed not only at preventing infection with the new coronavirus, but also at slowing the progression of these pathologies and their complications.

BACKGROUND: The study of the features of the formation of postoperative scars under the influence of rehabilitation programs in patients with chronic paraproctitis in the early postoperative period after minimally invasive surgical hospital-replacing technologies expands our understanding of the pathological condition and methods of its treatment.
AIM: To study the effect of various rehabilitation programs on the formation of postoperative scars in patients with chronic paraproctitis in the early postoperative period after minimally invasive surgical hospital-replacing technologies.
MATERIAL AND METHODS: The study summarized and analyzed the experience of surgical treatment of 180 patients with chronic paraproctitis using minimally invasive surgical hospital-replacing technologies and rehabilitation programs in the early postoperative period. Laser ablation of the fistula tract the classic FiLaC technology was performed in 90 patients; modified FiLaC technology 90. Each of the subgroups was divided into 3 groups: group 1 (main) included 30 patients who underwent a 4-component rehabilitation complex from the second day after the operation; group 2 (comparison) 30 patients who underwent a 2-component rehabilitation complex from the second day after the operation and group 3 (control) 30 patients, without an additional physiotherapeutic rehabilitation program. A comprehensive assessment of the features of the formation of postoperative scars was carried out as a criterion for the effectiveness of treatment, one of the tools of which was a complex transrectal ultrasound with color Doppler mapping, Dopplerography and sonoelastography at different stages of treatment.
RESULTS: All patients tolerated the course of treatment well: there were no cases of interruption of rehabilitation programs. The dynamic analysis of the data showed a statistically significant result: the best in patients of the main group against the background of a 4-component rehabilitation program, the formation of postoperative scars accelerated, the formation of a mature scar occurred earlier, the risks of developing postoperative complications and relapses of the disease decreased.
CONCLUSION: The use of rehabilitation programs in patients with chronic paraproctitis in the early postoperative period after minimally invasive surgical hospital-replacing technologies can improve clinical results due to the complex physiotherapeutic effect. Complex transrectal ultrasound with color Doppler mapping, Dopplerography and sonoelastography in patients with chronic paraproctitis is an effective non-invasive diagnostic method: monitoring the formation of a postoperative scar and assessing the ongoing treatment.

With an increase in requests for the correction of aesthetic imperfections with dermal fillers based on hyaluronic acid, cases of adverse events and complications have become more frequent. Hyaluronic acid in the form of a dermal filler is one of the most popular procedures in aesthetic medicine and has a high safety profile. Despite the fact that hyaluronic acid is an integral part of the extracellular matrix, fillers based on it can also cause complications. The use of an antidote in the form of hyaluronidase allows you to correct possible adverse reactions such as hypercorrection, the Tyndall effect, the formation of granulomas, and the development of tissue ischemia. Hyaluronidase is widely used in all branches of medicine, including the treatment of adhesions in the body, is used in in vitro fertilization, improves the absorption of drugs into the lesion in the treatment of cancer patients, and is also successfully used in the treatment of dermatological patients. In cosmetology, the use of enzyme helps to cope with such severe phenomena as tissue ischemia due to intravascular occlusion by the drug. And the use of ultrasound diagnostics makes it possible to correct adverse events using the enzyme strictly in the focus of the filler, thereby improving the quality of the treatment.

The whole world has been living in the conditions of the COVID-19 pandemic caused by the SARS-CoV-2 virus for more than 2 years. Despite the unprecedented measures aimed at finding new means of prevention and treatment, the development and implementation of vaccines, COVID-19 continues to be a significant medical and social problem. This is due to the peculiarity of SARS-CoV-2 to constant changes in the virus as a result of mutations and the formation of new strains. It affects the effectiveness of vaccination and treatment, necessitating preventive measures, primarily aimed at maintaining the normal functioning of the immune system that protects the host from various pathogens, including viruses. An important role in the state of the immune system is played by some micronutrients, which include zinc, selenium, iron and copper. Zinc and selenium have pronounced immunoregulatory, antioxidant and antiviral properties, iron is necessary for the growth and development of some cells of the immune system, and copper, in addition to its antiviral effect, reduces the risk of secondary infection in viral diseases. At the same time, according to the literature, more than 2 billion people in the world suffer from micronutrient deficiencies. In addition, there is often a combined deficiency of minerals, which necessitates its diagnosis and correction. Most of the studies we analyzed emphasize the importance of using micronutrients in people at risk, as well as in patients at the very beginning of the disease, in order to strengthen the immune system in the condition of a laboratory-confirmed deficiency.

Authors: KESKİN Necla
Published: September 2022

Seçici serotonin gerialım inhibitörleri (SSGİ) sıklıkla reçete edilen ve başlıca depresyon ve anksiyete bozukluklarının tedavisinde kullanılan ilaçlardır. SSGİ ilaçlar serotonin taşıyıcısını inhibe ederek trombositlerdeki serotinin düzeylerinde azalmaya yol açarlar. SSGİ ilaçlar başta paroksetin olmak üzere anormal kanamalarla ilişkilendirilmiştir. Yazıda genç, sağlıklı olup, paroksetin 20 mg/gün kullanımı sonrası spontan ekimoz gelişen, tedavisine paroksetinle devam edilen ve takiplerinde ekimotik lezyonların azalarak geçtiği gözlenen bir olgu sunulmuştur. SSGİ ilaçlarla ilişkili kanama gelişmesi durumunda; belirtiler hafif ve koagülasyon testleri normalse, tedaviye aynı ilaçla devam etmenin de bir seçenek olabileceği akılda tutulmalıdır. Bu konuda geniş ölçekli izlem çalışmalarına ihtiyaç vardır.

Published: September 2022

Cavernous hemangiomas (CHs) can be found in all intracranial structures, especially in the brain parenchyma. Most spinal hemangiomas are of vertebral origin. Spinal cavernous hemangiomas that do not hold the vertebrae are called "pure" types. Pure spinal epidural cavernous hemangiomas (SECHs) are very rare and account for approximately 4% of all epidural lesions. Here is a case of pure thoracic SECH detected in a 42-year-old female patient with progressive paraparesis and sensory loss below the T8 sensory dermatome for the last 2 months presented. Cavernous hemangioma should not be forgotten among the options in the differential diagnosis of spinal epidural tumors.

On 8 January 2022, an Mw 6.6 earthquake occurred along the Lenglongling fault (LLLF) (Menyuan, Qinghai Province, China), in the northeast margin of the Tibetan plateau. Here, we use imaging geodesy observations from pixel-offset tracking (POT) and Interferometric Synthetic Aperture Radar (InSAR) to quantify the coseismic displacement features and then combine InSAR and teleseismic velocity waveforms to constrain a finite-fault model to examine the kinematic slip behavior of the LLLF. We observe maximum displacements of >50 cm in the line-of-sight InSAR observations and >1 m in the east–west POT observations. Our preferred uniform-slip model indicates that the causative fault of this 2022 event ruptured the middle segment of the Qilian–Haiyuan fault (i.e., the LLLF) with a strike of 108.0°, a dip angle of 83.6°, and slip concentrated within a 15×8  km2 area and reaching a maximum value of 4 m. The total scalar seismic moment was 1.24×1019  N·m, and ∼67% of the energy was released in the first 6 s. We speculate that the 2022 event was controlled by complex fault geometries and slip partitioning, thus raising potential seismic risks associated with the outward extrusion of the plateau.
