Adipose tissue plays an active role in the regulation of the body’s energy balance. Mesenchymal stem/stromal cells from adipose tissue (adMSC) are the precursor cells for repair and adipogenesis. Since the balance of the differentiation state of adipose tissue-resident cells is associated with the development of various diseases, the examination of the regulation of proliferation and differentiation of adMSC might provide new therapeutic targets. Transforming growth factor-β1 (TGF-ß1) is synthetized by many cell types and is involved in various biological processes. Here, we investigated the effects of different concentrations of TGF-ß1 (1–10 ng/mL) on adMSC proliferation, metabolic activity, and analyzed the gene expression data obtained from DNA microarrays by bioinformatics. TGF-ß1 induced the concentration- and time-dependent increase in the cell number of adMSC with simultaneously unchanged cell cycle distributions. The basal oxygen consumption rates did not change significantly after TGF-ß1 exposure. However, glycolytic activity was significantly increased. The gene expression analysis identified 3275 differentially expressed genes upon exposure to TGF-ß1. According to the pathway enrichment analyses, they also included genes associated with energy metabolism. Thus, it was shown that TGF-ß1 induces changes in the energy metabolism of adMSC. Whether these effects are of relevance in vivo and whether they contribute to pathogenesis should be addressed in further examinations.

Published: February 2020

In this paper, we introduced a comparative study of Sm-Tm-substituted Sr-Ba nanohexaferrites (NHFs), Sr0.5Ba0.5TmxSmxFe12−2xO19 with x = 0.00–0.05, manufactured via both citrate sol-gel auto-combustion and ultrasonication approaches. The phase formation of M-type hexaferrite (HF) for both compositions was confirmed by X-ray diffraction (XRD) powder pattern, Fourier-transform infrared (FT-IR) spectra, scanning and transmission electron microscopy (SEM and TEM) micrographs, energy dispersive X-ray (EDX) spectra, and elemental mappings. The magnetic properties at room temperature (RT) and low temperature (T = 10 K) were also investigated. M-H loops revealed ferrimagnetic nature for various prepared nanohexaferrites via sol-gel and ultrasonication routes. The Ms (saturation magnetization) and Mr (remanence) values increased with increasing Tm-Sm substituting contents. Ms and Mr reached their maximum values at x = 0.04 in the case of samples prepared using the sol-gel technique and at x = 0.03 for those prepared via ultrasonication route. M-H loops were very broad in samples prepared via ultrasonication route in comparison to those produced by means of the sol-gel approach, implying that the products synthesized via ultrasonication route have greater values of coercivity (Hc). The variations in Hc values with respect to Tm-Sm substitutions were governed by the evolutions in the magneto-crystalline anisotropy. Diffuse reflectance spectra (DRS) were employed to estimate the direct band gap of pristine and co-substituted Sr0.5Ba0.5Fe12O19 hexaferrites. Optical energy band gaps (Eg) of pristine samples were significantly tuned by co-substitution of Tm3+ and Sm3+ ions. Eg values of the Sr0.5Ba0.5Fe12O19 sample, which was synthesized using the sol-gel method, decreased almost linearly from 1.75 to 1.45 eV by increasing co-doped ion content. However, we observed a sharp drop from 1.85 eV to an average of 1.50 eV for the samples, which were synthesized using the ultrasonication approach.
A Novel Route to High-Quality Graphene Quantum Dots by Hydrogen-Assisted Pyrolysis of Silicon Carbide

Published: February 2020

Graphene quantum dots (GQDs) can be highly beneficial in various fields due to their unique properties, such as having an effective charge transfer and quantum confinement. However, defects on GQDs hinder these properties, and only a few studies have reported fabricating high-quality GQDs with high crystallinity and few impurities. In this study, we present a novel yet simple approach to synthesizing high-quality GQDs that involves annealing silicon carbide (SiC) under low vacuum while introducing hydrogen (H) etching gas; no harmful chemicals are required in the process. The fabricated GQDs are composed of a few graphene layers and possess high crystallinity, few defects and high purity, while being free from oxygen functional groups. The edges of the GQDs are hydrogen-terminated. High-quality GQDs form on the etched SiC when the etching rates of Si and C atoms are monitored. The size of the fabricated GQDs and the surface morphology of SiC can be altered by changing the operating conditions. Collectively, a novel route to high-quality GQDs will be highly applicable in fields involving sensors and detectors.
Toward Large-Scale Production of Oxidized Graphene

Published: February 2020

The oxidative exfoliation of graphite is a promising approach to the large-scale production of graphene. Conventional oxidation of graphite essentially facilitates the exfoliation process; however, the oxidation procedure releases toxic gases and requires extensive, time-consuming steps of washing and reduction to convert exfoliated graphene oxide (GO) into reduced graphene oxide (rGO). Although toxic gases can be controlled by modifying chemical reactions, filtration, dialysis, and extensive sonication are unfavorable for large-scale production. Here, we report a complete, scalable, and green synthesis of GO, without NaNO3, followed by reduction with citric acid (CA). This approach eliminates the generation of toxic gases, simplifies the washing steps, and reduces the time required to prepare rGO. To validate the proposed method, we present spectroscopical and morphological studies, using energy-dispersive X-ray spectroscopy (EDS), UV-visible spectroscopy, infrared spectroscopy, Raman spectroscopy, scanning electron microscopy (SEM), and transmission electron microscopy (TEM). Thermal gravimetric analysis (TGA) is used to analyze the thermal properties of GO and rGO. This eco-friendly method proposes a complete guideline protocol toward large-scale production of oxidized graphene, with potential applications in supercapacitors, fuel cells, composites, batteries, and biosensors.

Authors: García Gregorio , Sánchez-Palencia Pablo , Palacios Pablo , Wahnón Perla
Published: February 2020

This work explores the possibility of increasing the photovoltaic efficiency of InP semiconductors through a hyperdoping process with transition metals (TM = Ti, V, Cr, Mn). To this end, we investigated the crystal structure, electronic band and optical absorption features of TM-hyperdoped InP (TM@InP), with the formula TMxIn1-xP (x = 0.03), by using accurate ab initio electronic structure calculations. The analysis of the electronic structure shows that TM 3d-orbitals induce new states in the host semiconductor bandgap, leading to improved absorption features that cover the whole range of the sunlight spectrum. The best results are obtained for Cr@InP, which is an excellent candidate as an in-gap band (IGB) absorber material. As a result, the sunlight absorption of the material is considerably improved through new sub-bandgap transitions across the IGB. Our results provide a systematic and overall perspective about the effects of transition metal hyperdoping into the exploitation of new semiconductors as potential key materials for photovoltaic applications.

Published: February 2020

As a derivative material of graphene, graphene oxide films hold great promise in thermal management devices. Based on the theory of Fourier formula, we deduce the analytical formula of the thermal conductivity of graphene oxide films. The interlaminar thermal property of graphene oxide films is studied using molecular dynamics simulation. The effect of vacancy defect on the thermal conductance of the interface is considered. The interfacial heat transfer efficiency of graphene oxide films strengthens with the increasing ratio of the vacancy defect. Based on the theoretical model and simulation results, we put forward an optimization model of the graphene oxide film. The optimal structure has the minimum overlap length and the maximum thermal conductivity. An estimated optimal overlap length for the GO (graphene-oxide) films with degree of oxidation 10% and density of vacancy defect 2% is 0.33 μm. Our results can provide effective guidance to the rationally designed defective microstructures on engineering thermal transport processes.
Epstein–Barr Virus and Helicobacter Pylori Co-Infection in Non-Malignant Gastroduodenal Disorders
Authors: Dávila-Collado Ramsés , Jarquín-Durán Oscar , Dong Le Thanh , Espinoza J. Luis
Published: February 2020

Epstein–Barr virus (EBV) and Helicobacter pylori (H. pylori) are two pathogens associated with the development of various human cancers. The coexistence of both microorganisms in gastric cancer specimens has been increasingly reported, suggesting that crosstalk of both pathogens may be implicated in the carcinogenesis process. Considering that chronic inflammation is an initial step in the development of several cancers, including gastric cancer, we conducted a systematic review to comprehensively evaluate publications in which EBV and H. pylori co-infection has been documented in patients with non-malignant gastroduodenal disorders (NMGDs), including gastritis, peptic ulcer disease (PUD), and dyspepsia. We searched the PubMed database up to August 2019, as well as publication references and, among the nine studies that met the inclusion criteria, we identified six studies assessing EBV infection directly in gastric tissues (total 949 patients) and three studies in which EBV infection status was determined by serological methods (total 662 patients). Due to the substantial methodological and clinical heterogeneity among studies identified, we could not conduct a meta-analysis. The overall prevalence of EBV + H. pylori co-infection in NMGDs was 34% (range 1.8% to 60%). A higher co-infection rate (EBV + H. pylori) was reported in studies in which EBV was documented by serological methods in comparison with studies in which EBV infection was directly assessed in gastric specimens. The majority of these studies were conducted in Latin-America and India, with most of them comparing NMGDs with gastric cancer, but there were no studies comparing the co-infection rate in NMGDs with that in asymptomatic individuals. In comparison with gastritis caused by only one of these pathogens, EBV + H. pylori co-infection was associated with increased severity of gastric inflammation. In conclusion, only relatively small studies testing EBV and H. pylori co-infection in NMGDs have been published to date and the variable report results are likely influenced by geographic factors and detection methods.

Authors: Jang Soo Min , Infante Sergio , Abdi Pour Amir
Published: February 2020

Acute kidney injury is very common in critically ill patients requiring renal replacement therapy. Despite the advancement in medicine, the mortality rate from septic shock can be as high as 60%. This manuscript describes drug-dosing considerations and challenges for clinicians. For instance, drugs’ pharmacokinetic changes (e.g., decreased protein binding and increased volume of distribution) and drug property changes in critical illness affecting solute or drug clearance during renal replacement therapy. Moreover, different types of renal replacement therapy (intermittent hemodialysis, prolonged intermittent renal replacement therapy or sustained low-efficiency dialysis, and continuous renal replacement therapy) are discussed to describe how to optimize the drug administration strategies. With updated literature, pharmacodynamic targets and empirical dosing recommendations for commonly used antibiotics in critically ill patients receiving continuous renal replacement therapy are outlined. It is vital to utilize local epidemiology and resistance patterns to select appropriate antibiotics to optimize clinical outcomes. Therapeutic drug monitoring should be used, when possible. This review should be used as a guide to develop a patient-specific antibiotic therapy plan.
Approximate and Situated Causality in Deep Learning
Authors: Vallverdú Jordi
Published: February 2020

Causality is the most important topic in the history of western science, and since the beginning of the statistical paradigm, its meaning has been reconceptualized many times. Causality entered into the realm of multi-causal and statistical scenarios some centuries ago. Despite widespread critics, today deep learning and machine learning advances are not weakening causality but are creating a new way of finding correlations between indirect factors. This process makes it possible for us to talk about approximate causality, as well as about a situated causality.

Masculinity in the Sikh Community in Italy and Spain: Expectations and Challenges
Authors: Garha Nachatter Singh
Published: February 2020

Since the 1990s, the Sikh community in India has entered a phase of considerable socioeconomic and demographic transformation that is caused by the large-scale practice of female feticide, the spread of higher education among women, and the mass emigration of unskilled men to the Western countries. These changes have a great impact on the traditional configuration of gender roles and disrupt the construction of masculinity in the Sikh community in India and in the diaspora. Based on ethnographic observations and 64 in-depth interviews with Sikh immigrants in Spain (26) and Italy (22) and their relatives in India (16), this paper first explores the expectations of masculinity in the Sikh community in Italy and Spain; and second, analyses the challenges that are imposed by the socioeconomic and demographic transformation in the Indian Sikh community and the social environment in the host countries on the construction of masculinity in the Sikh community in both countries.
Analysis of Commuting Distances of Low-Income Workers in Memphis Metropolitan Area, TN
Authors: Antipova Anzhelika
Published: February 2020

The paper tests whether low-income workers suffer a greater commuting cost burden compared with a typical commuter within the context of decreasing economic opportunity. The paper adds to the spatial mismatch research by studying the metropolitan area in the U.S. South, which experienced “some of the largest decreases” in job proximity in 2012. Memphis, Tennessee, saw the disproportionately steep declines in the average employment opportunities within a typical commute distance experienced by low-income and minority residents. The paper first delineates low-income neighborhoods across the study area, then identifies commuting patterns within the three-state study area including the greater Memphis, and lastly, it compares average commute lengths by a typical and a low-income commuter, as well as the shares of resident workers with a long commute by earning category. The paper offers insight into the ways in which the changes in spatial location of employment and population within the metropolitan area may impact commuting distance for disadvantaged low-income travelers. We show low-income workers commute statistically significantly shorter distances to their places of work compared with a typical commuter. Our other results find that disadvantaged workers in Shelby County, TN, are disproportionately concentrated in lower-wage industries, such as hospitality and retail service industries, compared to overall workers. Finally, a significantly greater proportion of disadvantaged workers travel long distances of over 50 miles compared with higher-earning workers, indicating the disparity in commuting patterns between a typical resident and a low-income worker.

Um altar para o deus desconhecido
Authors: Motta Leda Tenório da
Published: February 2020

Perguntava-se Mallarmé, em "Os deuses antigos" se, acaso, algum espírito imbuído de preconceito acreditaria que as divindades já não têm mais lugar na terra. Contra tal prevenção respondia acenando com a poesia: a leitura das mais belas páginas das letras francesas mostra que nada morreu de tudo aquilo que foi um dia o culto espiritual da raça. O intento do presente artigo é destacar que a pergunta e a resposta do poeta estão no centro vivo da argumentação de Olgária Matos. Que, para ela, lendas fazem todo o sentido, aqui e agora, na situação moderna. Que a embriaguez com que se cumpre o trato do mundo antigo com o cosmos, antes que a ciência venha a desenfeitiçá-lo, a tem interessado muito mais que a denúncia do desencanto da ciência, nisso residindo sua marca interessante.

La semilla de tomate de cáscara (Physalis ixocarpa Brot. ex Horm.) que se usa en México en general es de baja calidad física, fisiológica y genética. Para producir semilla de alta calidad es necesario contar con variedades mejoradas y tecnología adecuada para su producción y beneficio. Se compararon dos máquinas para la extracción de semilla (molino eléctrico y despulpadora) con el objetivo de estudiar su eficiencia y efecto sobre el rendimiento y calidad de semilla de cuatro variedades mejoradas de tomate de cáscara (Diamante, Tecozautla 04, Gema y Manzano Tepetlixpa). La investigación se llevó a cabo en Chapingo, Estado de México, de julio a octubre de 2013, con un arreglo de tratamientos factorial 2 × 4, bajo un diseño experimental completamente al azar con cuatro repeticiones. Se extrajo y benefició la semilla de 1000 kg de fruto por unidad experimental. Se evaluó el tiempo total del proceso de extracción, rendimiento de materia prima (semilla sin beneficio), peso de semilla seca clasificada por tamaño (chica, estándar y grande), contenido de humedad de la materia prima en tres etapas del proceso de secado y germinación de semilla en cuatro etapas del proceso de beneficio. Se obtuvo el menor tiempo total de proceso y el mayor rendimiento de semilla con la máquina despulpadora. Con ambas máquinas se obtuvo la misma calidad fisiológica de la semilla. Las variedades evaluadas produjeron semilla de calidad fisiológica similar, aunque con diferente rendimiento de semilla. Existe interacción significativa entre máquinas y variedades para rendimiento de materia prima y de semilla beneficiada, al igual que para germinación.

Authors: Reshotkin O. V.
Published: February 2020

Aim. Identify patterns of temporal changes in the parameters of the atmospheric and soil climates of humid subtropics. Methods. The dynamics of air and soil temperature and precipitation are analyzed in the long-term and seasonal cycles with respect to the climatic normal, which is considered as a quantitative characteristic of the conditions of pedogenesis and climate variability over time. Results. The data on air temperature, precipitation and soil temperature yellow soils, formed in a subtropical wet-forest soil bioclimatic area are analyzed. It is shown that the average annual air temperature in 2001 - 2018 exceeded the climatic normal by 0,7°C, the annual precipitation increased by 104 mm. Modern warming leads to a change in the temperature regime of yellow soils. The average annual soil temperature at the beginning of the XXI century increased from 0,5°С at the depth of 320 cm to 0,9°С at the depth of 20 cm. The sum of active soil temperatures above 10°С at the depth of 20 cm increased by 283°С. Main conclusions. In the modern period, a change in the atmospheric and soil climate towards warming is observed in the zone of distribution of yellow soils of humid subtropics of Russia, accompanied by an increase in precipitation. Warming is most pronounced in the summer season and is practically not observed in the winter season. It is characterized by an increase in air and soil temperature throughout its profile, an increase in the sum of active temperatures. The revealed climate changes make it possible to re-evaluate the soil and agroclimatic resources of the Russian subtropics for agriculture and forestry.

The Influence of the Soaking Process on Magnetization Saturation and Coercivity Field of the Classic Amorphous Alloy Fe61Co10Y8Nb1B20.
Authors: Nabialek Marcin
Published: February 2020

This study presents the results of Mossbauer research and magnetic properties. The tests were carried out for amorphous Fe61Co10Y8Nb1B20 alloys produced in the form of strips with a thickness of approximately 35 mm. Mossbauer spectra were measured in transmission geometry for solid samples. Measurements were taken for samples in solidified state and after two heating processes. The first process was carried out at 700K and 60 minutes, the second at 720K and 210 minutes. For the samples prepared in this way, magnetization tests were performed as a function of the magnetic field strength. The values of saturation magnetization and the value of the coercive field were determined from these matrices. It was found that the performed thermal treatments had a negative effect on the value of saturation magnetization and change in the value of the coercive field.

The paper addresses the usage of the intrinsic security features which is a challenge for lowering the document protection costs. Three types of papers were investigated using ESEM-EDS and ED(P)-XRFS in order to identify and characterize overt and covert intrinsic items. The paper shows that some of the intrinsic morphological features of document paper can be successfully used as taggants. The chemical compositions can be used as internal marks for forensic authentication of the ballpoint pen imprints. Two new ways are proposed for enhancing the document safety protection: the usage of the fractal dimension of the paper pattern and the intentional admixture into paper mass of cheaper substances as taggants in conjunction with SEM and XRF techniques.

The present paper systematizes the results of the research on the effect of wheatgrass juice administration on some important indicators in assessing the physiological state of two summer-old Cyprinus carpio individuals coming from a recirculating system, as well as on some biochemical parameters with role in the antioxidant defensive. For this, an experiment was carried out over a period of 56 days, which consist in growth of 200 carp specimens, with an initial average weight of 72.85�1.79 g/specimen. Observations carried out during the entire monitoring period of the experimental variants emphasized a good sanitary status of the studied specimens, accompanied by an active feeding behavior. The results on the activity of oxidative stress enzymes and malon-dialdehyde concentration emphasized significant differences between the treated variants with wheatgrass juice and the control variant, closely related to the wheat juice concentration with which the food ration was supplemented.

In recent years, the growing dynamics of the investments for new civil and industrial construction projects involves new properties acquisitions. On the other hand, there is an increase in the conversion of some industrial sites into commercial or residential areas, after their acquisition by the new owners. It is very important to knows the quality of the environmental components in the areas where the new investment projects are being implemented. Most of the time, the acquisition of a land or industrial site is preceded and, in many cases, conditioned by a thorough assessment of the quality of the environmental components in order to assume responsibilities for the ensuing environmental obligations. This involve environmental assessment performed by specialists who can objectively and analyze relevant environmental issues and report the necessary conclusions and recommendations for each case. The paper presents the expertise of the National Research and Development Institute for Industrial Ecology specialists in a study that analyzed soil, groundwater and air quality in order to develop new investments projects. The presented conclusions converge towards the important role of the environmental assessment based on the relevant information analyzed for each case and the importance of environmental information in preparing new investments.

The waterborne pathogenic bacteria, especially the enteric bacteria of human fecal origin, have become currently a global public health issue. The detection and quantification of drinking water microorganisms have been an essential part of any quality control or water safety management plan interconnected to enteric bacterial pathogens such as Salmonella spp., Shigella spp., Vibrio cholerae or to non-faecal bacterial pathogens such as Pseudomonas aeruginosa. The standard methods of detecting waterborne pathogenic bacteria are time-consuming due to the bacterial growing step in a specific culture media, followed by isolation, microbiological and/or serological identi�cation and in some cases followed by subspeci�c characterization. This study aimed to develop a faster, powerful, more sensitive and reproducible diagnostic tool to monitor a specific pathogen contamination in drinking water (Pseudomonas aeruginosa) by specific antibody-antigen interactions followed by a computerized technology to identify bacteria as a digital image from water samples. Digital Image processing was carried out using National Instruments Vision Assistant Software. Pseudomonas aeruginosa was specifically detected by immunofluorescence technique with fluorophore tagged antibodies, and then the image formation in fluorescence microscopy was processed by computer vision software functions organized in pipeline-like data analysis processing. Overall, these techniques proved to be a reliable one, time-effective and sensitive for diagnosis and prevention of drinking water quality and waterborne bacterial disease.

Arthroplasty of the hip, for either arthritic changes or femoral neck fracture, is a common procedure in orthopedic surgery. Although the standard designs for implantation, either cemented or uncemented, are well described and studied, there are also alternative designs regarding the implantation of both prosthetic stem and cup. This paper aims to explore one such alternative design, using the screw-in technique. It has been described in past literature for uncemented fixation of both the cup and the stem, and the biomechanical principles of fixation are different from the classical methods, offering certain advantages that are insufficiently explored in current-day endoprosthesis. Also, we will be presenting an innovative femoral stem design, recently developed, that combines an uncemented screw-on technique with a cemented augmentation possibility, aimed to provide the practitioner with the advantages of a bone-preserving mini-stem design, combined with the innovative screw-in fixation technique and the versatility of the hybrid cemented/uncemented fixation method.

Ureteral stenting has become one of the most common endoscopic procedure in endourology. Its main purpose is to preserve urinary drainage if this is compromised and maintain a good renal function. Even if there were made significant improvements in the last 50 years, ureteral stenting is not without morbidity. The common ureteral stents cannot have a good long-term efficiency and at some points, it will be blocked by the encrustation and incrustation; as result, the urinary drainage will have to suffer. A total of 134 ureteral stents in 83 patients suffering from reno/ureteral lithiasis were examined. We investigated the risk factors of encrustation and analyzed the chemical compounds of it. A total of 57 stents were found encrusted. The main risk factor was represented by the indwelling time. The rate of encrustation was 18.33% in the first 5 weeks, 56% between week 6 and 12, 75% thereafter. Stents with a smaller caliber (4.8 CH) tend to be more encrusted than those with a bigger one (6 CH). The Fourier Transform Infrared Spectroscopy has found that the main chemical compound of encrustation is represented by calcium oxalate.

The paper presents one part from the RATEN ICN contribution to the European FP7 MatISSE Project objectives, which is focused on the fracture mechanics properties of small tubes made from ODS steels (Oxide Dispersion Strengthened steels). The ODS tubes are foreseen as cladding tubes for gen IV reactors, and therefore the mechanical properties are very important for working in the most aggressive environment (irradiation and high temperatures) during the gen IV reactor operation. The fracture toughness, KIC, could be obtained for tubes with small diameters by means of the PLT-type mechanical test (acronym for Pin-Loading Test). This kind of test is a non-standard (ASTM) mechanical test, and during last decade it is still worldwide under development. The specific specimens for PLT-tests has been prepared from ODS tubes, which were provided to the project by the CEA France, a partner in the FP 7 MatISSE, in two different compositions: Fe -9cr ODS and Fe -14 Cr ODS. The paper highlights the PLT experimental test methodology, starting with obtaining of the geometric function, description of the experimental set-up and results processing.
