Published: April 2022

Obesity is a complex disease that causes serious impact health, such as diabetes mellitus, cardiovascular disease, cancer, and stroke. An early obesity diagnosis/ detection method is required to prevent the increasing number of obese people. This study aims to: (i) fine-tune the pre-trained Convolutional Neural Network (CNN) models to build an early detection of obesity and (ii) evaluate the model performance in terms of classifying performance, computation speed, and learning performance. The thermal images acquisition procedure was conducted with 18 normal subjects and 15 obese subjects to build a thermal images dataset of obesity. Pre-trained CNN models: VGG19, MobileNet, ResNet152V, and DenseNet201 were modified and trained using the acquired dataset as the input. The training results show that the DenseNet201 model outperformed other models regarding classifying accuracy: 83.33 % and learning performances. At the same time, the MobileNet model outperformed other models in terms of computation speed with training elapsed time: 12 seconds/epoch. The proposed DenseNet201 model was suitable for implementation as an early screening system of obesity for health workers or physicians. Meanwhile, the proposed MobileNet model was suitable for mobile applications' early detection/diagnosis of obesity.

The study objective– to present a clinical case of axillary nerve neurolysis performed through arthroscopic transcapsular access.Clinical case.Patient Ch., 38 years old, received a fracture of the head of the left humerus as a result of a fall 5 months ago. Immediately after the injury, symptoms of axillary nerve damage appeared. Conservative therapy was carried out without positive dynamics. According to ultrasound and electroneuromyography, signs of compression of the axillary nerve were noted without violating its anatomical integrity. The pathological substrate was located in the neck of the humerus, in the “blind” zone of the nerve. The situation was complicated by the progression of the phenomena of arthrosis of the joint with the formation of pain. Performed acroscopic transcapsular neurolysis of the axillary nerve with sanitation of the cavity of the shoulder joint. After 2 months, a visual increase in deltoid muscle volume and range of motion in the shoulder joint was noted.Conclusion.Arthroscopic transcapsular axillary neurolysis is, from our point of view, a promising minimally invasive intervention with the ability to perform simultaneous surgery by a multidisciplinary team. It is necessary to compare the results of the operation with arthroscopic and open access.
Reply to “Comment on ‘The 373 B.C. Helike (Gulf of Corinth, Greece) Earthquake and Tsunami, Revisited’ by ” by Dora Katsonopoulou and Ioannis Koukouvelas
Authors: Stiros Stathis C. 
Published: April 2022

Abstract
This reply is a response to a comment criticizing a recent article proposing a new scenario for the 373 B.C. earthquake, derived from ancient texts. This earthquake and a following tsunami are reported to have destroyed Helike and Boura, two ancient Greek towns, which then were found submerged into the Gulf of Corinth, punished by Poseidon, an ancient Greek god. The comment contested the new scenario that these ancient texts reflect a later legend, of Roman times. The comment is unsubstantiated, because (1) ruins of the two towns, invisible till recently, have been found in archaeological excavations, without any signs of a marine regression, while no significant marine regression is derived from sedimentological data; (2) Helike and Boura were town–states consisting of smaller villages, located at elevations above 20 and 500 m, respectively, and their subsidence into the sea was impossible; (3) ancient authors writing shortly after 373 B.C. ignore the loss of Helike and Boura; and (4) ancient texts reporting the loss are much later, of Roman times (&gt;200 yr after 373 B.C.), and they reflect a local legend and manipulated or forged ancient texts, for example by pseudo-Aristotle. The scenario proposed in Seismological Research Letters represents the only realistic explanation for the ancient texts referring to the 373 B.C. earthquake.
En búsqueda de acuerdos sobre los fines pedagógicos que han de regir en la Educación Física
Authors: Hortigüela-Alcalá David , Pérez-Pueyo Ángel , Hernando-Garijo Alejandra 
Published: April 2022

Actualmente son numerosos los desacuerdos en torno a la enseñanza de la Educación Física (EF), incluso hacia sus intenciones, finalidades y funciones. Esta variedad de enfoques, en muchos casos opuestos, se agudiza notoriamente por la influencia de las redes sociales. La búsqueda del “like” y el halago inmediato deriva en un reduccionismo de la materia, más mediatizado por la ocurrencia de la actividad concreta que por la evidencia científica. Esto, junto a otros factores, limita que la asignatura goce del prestigio social y curricular que merece. El objetivo del presente artículo es intentar arrojar luz sobre los principios fundamentales que han de estructurar la enseñanza de la EF. A través de la revisión de la literatura, se presentan diez elementos clave: 1.- Plantear propuestas con coherencia pedagógica; 2. - Crear una identidad corporal dentro de la cultura de la actividad física y el deporte; 3.- Generar un clima social positivo en el aula; 4.- Trabajar la inclusión y romper estereotipos; 5.- Utilizar los modelos pedagógicos; 6.- Aplicar la evaluación formativa y compartida; 7.- Evidenciar el aprendizaje generado; 8.- Fomentar la autorregulación; 9.- Promover la transferibilidad del aprendizaje; 10.- Conocer/transformar el entorno y el servicio a la comunidad. El texto, sin ninguna pretensión de sentar cátedra, busca la reflexión pausada y profunda del profesorado de EF, un colectivo de gran dinamismo, potente y con infinidad de posibilidades para conseguir que la asignatura siga creciendo y evolucionando.

The relevance. An increase in the contribution of renewable energy sources to the generation of the autonomous hybrid energy industry is important in order to reduce the environmental impact of diesel generator plants and decrease operating costs in the production of electrical energy in smart microgrids with distributed generation, including so-called «green» generation. This issue has the highest relevance for cell towers of mobile communication, rotational residential camps, meteorological stations and other remote consumers, the rated capacity of which is tens to hundreds of kW. Objective: the development of computer models for optimizing the management of the operational staff and modes of an autonomous photo-diesel power supply system with a DC bus, so as to make it possible to minimize the operating time of a diesel generator plant by increasing the contribution of the photovoltaic plant at optimal technical and economic indicators. The use of a DC bus for the electricity integration from distributed energy sources is considered promising in reducing the number of hours of inefficient operation of a diesel generator plant, which will make it possible to save diesel fuel and extend the life expectancy of the diesel generator. Novelty. This work expands the known options for modeling and optimizing the modes of a standalone hybrid DC power plant in terms of using an objective function with appropriate restrictions, adapting models of power equipment for the intended purposes of modeling, presenting the structure of a feasibility study based on commercially available characteristics of the elements of the power supply system. Methods. The study entails the development of computer models of the intelligent control architecture of a standalone hybrid power plant including a photovoltaic plant, a diesel generator plant, an electric energy storage system, a remote consumer, as well as auxiliary converter devices. Modeling of control processes is implemented in the Stateflow library, as well as by using the language syntax of the Matlab high-level package, the capabilities of which are acceptable for the intended purposes. Results. The analysis of the results shows that DC PV-diesel power supply systems can be cost-effective in all scenarios that include different types of batteries while for systems without power storage, DC distribution is often not cost-effective. The results will be of interest to specialists developing or operating standalone power supply systems and organizations planning to upgrade existing diesel power plants.
The Development of Rationality in Economics
Authors: Lü Rongxia , Hao Fei 
Published: April 2022

The concept of rationality first originated from philosophy and later evolved into rationality in economics, and then rationality has been the basic assumption of mainstream economics. With the development of economics and the integration of multiple disciplines, the concept of rationality in economics has been expanded and evolved, and different economic schools have put forward their own concepts of rationality. Classical and neoclassical economics advocate the complete rationality based on the hypothesis of "economic man"; later, behavioral economics and other schools have questioned the complete rationality, and they have proposed bounded rationality or irrationality; in fact, some other scholars have also proposed some other concepts of rationality, such as “evolutionary rationality”, “reasoned scrutiny rationality”, “cognitive rationality” and so on, which have made the concept of rationality in economics develop continuously. This paper briefly reviews the sources of the concept of rationality, the concept of rationality in traditional economics, the theory of bounded rationality and the other theories of rationality, in order to clarify the abstract concept of rationality.
Analytical Time-Dependent Shape Factor for Counter-Current Imbibition in Fractal Fractured Reservoirs
Authors: Mei Lan , Wei Wei , Cai Jianchao , Meng Qingbang 
Published: April 2022

Summary
The fluid exchange behavior for counter-current imbibition in fractured reservoirs can be quantitatively characterized by the transfer function in numerical simulation. The time-dependent shape factor (TDSF) in the transfer function is one of the main factors controlling fluid transport, which directly affects the result of ultimate oil recovery prediction. In practice, fractured reservoirs with different microscopic pore structures often have varied flow laws under the same flow conditions. However, the current TDSFs proposed for counter-current imbibition assume that the microscopic pore structure has no impact on the fluid inter-porosity flow behavior, which is inconsistent with the actual situation. In this work, the fractal theory is used to establish the TDSF of counter-current imbibition, which is related to the microscopic pore structure. First, the analytical solutions of average water saturation and imbibition rate are obtained under different conditions related to the maximum pore diameter and tortuosity fractal dimension of the matrix. The validity of the new analytical solution for strong water-wet and moderate water-wet reservoirs is ascertained by a single-porosity model and experimental data. Subsequently, the proposed analytical solution is applied to the two-phase transfer function to develop the new TDSF for counter-current imbibition, and the sensitivity analysis is carried out. The results demonstrate that the unsteady-state duration of the TDSF is proportional to the characteristic length and tortuosity fractal dimension of the matrix, and it is negatively proportional to the maximum pore diameter of the matrix. The influence of the characteristic length, tortuosity fractal dimension, and maximum pore diameter of the matrix on a constant shape factor (SF) under quasi-steady-state is exactly the opposite. This work provides an enhanced clarification of the fluid exchange behavior of counter-current imbibition in strong water-wet and moderate water-wet fractured reservoirs.

Published: April 2022

Abstract
Background:It is well known that copper oxide nanoparticles (CuO NPs) are heavily toxic on in vitro systems. In human alveolar epithelial cells, the mechanism of toxicity is mostly related to oxidative insults, coming from intracellularly dissolved copper ions, finally leading to apoptotic or autophagic cell death.Our hypothesis is based on possible early oxidative events coming from specific NP surface reactivity able to undermine the cell integrity and to drive cell to death, independently from lysosomal-enhanced Trojan horse mechanism. Two types of CuO NPs, with different oxidative potential, were selected and tested on A549 cells for 1h and 3h at 10, 25, 50 and 100 mg/mL. Cells were then analyzed for viability and oxidative change of the proteome. Oxidative by-products were localized by immunocytochemistry and cell-NP interactions characterized by confocal and electron microscopy techniques.Results:CuO NPs induced oxidative changes soon after 1 h exposure as revealed by the increase in protein carbonylation and reduced-protein-thiol oxidation. In parallel, cell viability significantly decreased, as shown by MTT assay. Such effects were higher for CuO NPs with more crystalline defects and with higher ROS production than for fully crystalline NPs. At these exposure times, although NPs efficiently interacted with cell surface and were taken up by small endocytic vesicles, no ion dissolution is visible inside endo-lysosomal compartment and no effects were produced by extracellularly dissolved copper ions.Conclusions:A specific NP surface-dependent oxidative cell injury was demonstrated. More detailed studies are required to understand which targets precociously react to CuO NPs, but these results introduce new paradigms for the toxicity of the metal-based NPs, beyond the Trojan horse-related mechanism, and opens-up new opportunities to investigate the interactions and effects at the bio-interface for designing safer as well as more effective CuO-based biocides.

Abstract
Background
We analysed the clinical and therapeutic profile of the patients who underwent a surgical lower extremity amputation (LEA) in Togo.
Methods
Retrospective study based on clinical files of the adult patients who underwent a LEA at a single centre (Sylvanus Olympio Teaching Hospital, SOTH) from 1st January 2010 to 31st December 2020. We analysed files with 95% of the studied parameters and excluded those with less than 5%. Data were analysed by CDC Epi Info Version 7 and Microsoft Office Excel 2013 software.
Results
We included 245 cases. The mean age was 59.62 years (15.22SD) (range 15 to 90 years), the sex ratio, 1.99. The medical history of diabetes mellitus was found in 143/222 (64.41%). Gangrene was diagnosed in 212/245 (86.53%) patients; crush syndrome in 23/245 (9.39%); bone tumour in 5/245 (2.04%); osteomyelitis in 2/245 (0.82%); chronic ulcer in 2/245 (0.82%); necrosis fasciitis in 1/245 (0.40%). A Doppler-ultrasound of the lower limbs was performed in 91/245 (37.14%) cases. The anatomical site of LEA found in 241/245 (98.37%) files was leg in 133/241 (55.19%), knee in 14/241 (5.81%), thigh in 83/241 (34.44%), and foot in 11/241 (4.56%) patients. The mean delay from the indication of amputation to surgery retrieved in 239/245 (97.55%) files was 6.75 (1–78) days (11.59 SD). The immediate postoperative complications have been reported in 242/245 (98.78%) files, and no complication in 234/242 (96.69%). There were early complications in 56/238 (23.53%) patients. The mortality rate after LEA was 17/238 (7.14%). The mean duration of hospitalization marked in 241/245 (98.37%) files was 36.30 (1-278) days (36.20SD).
Conclusion
Most patients admitted to SOTH (Lomé, Togo) who underwent LEA had diabetes mellitus at the late presentation, which led to challenging complications. This result entails essential information campaigns to prevent diabetes mellitus and cardiovascular diseases.

Abstract
Background: Cardiovascular diseases (CVDs) are prevalent globally and are increasing tremendously. This article aimed to determine the prevalence and prevalence odds ratio of seven CVD risks among working people (18-64 years) in Malaysia.Methods: A cross-sectional study among a nationally representative sample in Malaysia was conducted using a validated questionnaire. Clinical procedures were performed by registered nurses to measure glucose, cholesterol, body mass index and blood pressure. The prevalence and prevalence odds ratio were calculated via complex sample data analysis of IBM SPSS Statistics version 25.Results: The overall prevalence of CVD risks among working people was 14.1%, 17.3%, 24.5%, 28.8%, 31.7%, 45.9% and 94.2% for diabetes, obesity, hypertension, physical inactivity, tobacco smoking, hypercholesterolemia and inadequate fruit and vegetable (FV) intake, respectively. This study found that older age was associated with the odds of having the most CVD risks. Males were associated with higher odds of having hypertension and tobacco smoking, whereas females were more likely to have hypercholesterolemia, obesity, and physical inactivity. Those who worked as manager & senior officials, clerical workers and services & sales workers were physically inactive, while workers from the lower educational level were more likely to smoke tobacco. Workers in the public sector were more likely to have a higher prevalence of diabetes, hypertension, hypercholesterolemia, smoking and obesity than workers in the private sector.Conclusions: This study highlighted that working people have significant CVD risks and a regular medical screening should be conducted at workplace settings.

Published: April 2022

Abstract
2,2,6,6-tetramethylpiperidine-1-oxyl-radical (TEMPO) oxidized is a classical method to obtain carboxyl chitin nanomaterials, but when the traditional TEMPO/NaBr/NaClO (TBN) oxidation system was oxidizing β-chitin, it was only suitable for β-chitin with a degree of deacetylation (DD) of 1%. Herein, the high yield carboxyl β-chitin nanofibers (CO-ChNFs) were successfully prepared from squid pen β-chitin with partially deacetylated (DD: 5–30%) using the TEMPO/NaClO/NaClO2 (TNN) oxidation system. The results show that the DD of purified β-chitin has a great impact on the yield of CO-ChNFs, and the yield is as high as 98% when the DD of β-chitin was 11%. XRD results showed that β-chitin undergoes slight of β-α transformation after TNN TEMPO oxidation, and the 010 crystal planes are arranged more closely. AFM characterization suggests that thus prepared CO-ChNFs have a diameter of 2–6 nm and a length in the micrometer range. The proposed preparation method breaks through the previous limitation of TEMPO oxidation in the application of β-chitin, and will facilitate the in-depth research and application of carboxyl β-chitin nanofibers.

Abstract
Background
In this study we investigated the therapeutic potential of the phytosomal form of pharmacologically active component of Curcuma longa, curcumin, in attenuating Post-operative adhesion bands (PSAB) formation in both peritoneal and peritendinous surgeries in animal models.
Methods
Bio-mechanical, Histological and quantitative evaluation of inflammation, and total fibrosis scores were graded and measured in the presence and absence of phytosomal curcumin.
Results
Our results showed that phytosomal curcumin significantly decreased severity, length, density and tolerance of mobility of peritendinous adhesions as well as incidence and severity of abdominal fibrotic bands post-surgery. We showed that curcumin could decrease inflammation by attenuating recruitment of inflammatory cells and regulating oxidant/anti-oxidant balance in post-operative tissue samples. Moreover, markedly lower fibrosis scores were obtained in the adhesive tissues of phytosomal curcumin-treated groups which correlated with a significant decrease in quantity, quality and grading of fibers, and collagen deposition in animal models.
Conclusion
These results suggest that the anti-inflammatory and anti-fibrotic properties of phytosomal curcumin, has therapeutic potential for preventing PSAB formation.”
