Authors: DAS MAHAPATRA GAURAB , Mori Suguru , Nomura Rie
Published: December 2021

In this research, the accessibility in the footpath-level walkability condition of old core cities of India has been assessed, considering Central Kolkata, India as a case. Post-2015, after the implementation of Goal Number 11 of United Nations Sustainable Development Goals (i.e. Sustainable Cities and Communities), the significance of universal mobility has globally manifolded in the walkability sector. This research has been done in theoretical, ideological, and methodological patterns using Architectural Planning Research for promoting Universal Mobility in old Indian cities. The variables (categorical) used in this research are related to pedestrian infrastructure. The categorical variables are: 1) Building Typology of Stretch, 2) Footpath Dimensions, 3) Temporary Encroachment, 4) Permanent Encroachment, 5) Bus Stop, 6) Metro Rail Entrance, 7) Railings, 8) Storm Water Drains, 9) Public Toilet, 10) Trash Bins, 11) Street Lights, 12) Flooring, 13) Manholes, 14) Kerb, 15) Pedestrian Crossing, 16) Street Furniture, 17) Safety and Security, and 18) Additional Inclusive Features like signage. This research shows that the footpath stretches in Central Kolkata, India are inadequate in terms of ideal accessibility. In addition to this, the result of this research portrays complexities in the adaptability of accessible walkability-related considerations; thereby suggesting a new accessibility audit format for old core Indian cities for achieving Universal Mobility standards in the future. The authors also propose quantitative methods to conduct future research in the same domain.

Published: December 2021

Shallow bathymetry inversion algorithms have long been applied in various types of remote sensing imagery with relative success. However, this approach requires that imagery with increased radiometric resolution in the visible spectrum is available. The recent developments in drones and camera sensors allow for testing current inversion techniques on new types of datasets. This study explores the bathymetric mapping capabilities of fused RGB and multispectral imagery, as an alternative to costly hyperspectral sensors. Combining drone-based RGB and multispectral imagery into a single cube dataset, provides the necessary radiometric detail for shallow bathymetry inversion applications. This technique is based on commercial and open-source software and does not require input of reference depth measurements in contrast to other approaches. The robustness of this method was tested on three different coastal sites with contrasting seafloor types. The use of suitable end-member spectra which are representative of the seafloor types of the study area and the sun zenith angle are important parameters in model tuning. The results of this study show good correlation (R2>0.7) and less than half a meter error when they are compared with sonar depth data. Consequently, integration of various drone-based imagery may be applied for producing centimetre resolution bathymetry maps at low cost for small-scale shallow areas.

Published: December 2021

The evolution of digital media in adolescents has changed the patterns and motives of use and the impact on their communication choices in their social and family networks. The objectives of this study are to understand how peers communicate adopting a social network (SN) or by voice and their social desirability. After the informant consent signature, the adolescents completed a series of self-report questionnaires on the use of SN, on communication preferences, and on social desirability through online. Most of the adolescents belonged to the 17-19 age group (83.6%) and were female (68.9%). Adolescents spent more than 3 hours/day on Whatsapp and more than 2 hours/day on Instagram, while the use of Facebook was on average only 35 minutes/day. Females used digital media for longer than males. Adolescents aged 17-19 years choose more Facebook and voice modes compared to adolescents aged 14 and 16 years. The alternative modes of Whatsapp and voice were chosen more than the social networks in their communication strategies, especially for negative topics. Motives for use were, in addition to boredom, related to maintaining one's social sphere with peers. Some educative considerations were made based on these results.

Authors: Akter Kazi Mahmuda , Umar Badar Uddin , Rahman S M Niazur
Published: December 2021

Background/Aims: Screening for gestational diabetes mellitus (GDM) are currently done at 24 - 28 weeks of conception, missing out on the most vulnerable period of organogenesis and thus preventing clinicians from starting treatments until the late second or third trimester. MicroRNAs (miR) are small non-coding RNA molecules that could aid in detecting or predicting GDM through establishing a novel non-invasive prenatal testing (NIPT) tool. The objective of this study was to summarize the most recent updates on plasma microRNAs as GDM diagnostic biomarkers. Methods: Between April and June 2021, a PubMed literature search was undertaken to review recent articles on human plasma miR associated with GDM. Animal studies and papers that are written in languages other than English were excluded. Only plasma miRNAs were used to avoid coagulation biases. Results: A total of 31 miRNAs were found significantly upregulated in the plasma samples of patients with GDM. It was found mainly during the 2nd or 3rd trimester except for miR-223 and miR-23a that were upregulated at 9 – 11 weeks of gestation. Conclusion: Though extensive prospective cohort studies are required, miR-223 and miR-23a should be considered the most promising to develop a successful NIPT tool because they were found to be upregulated earliest, during the first trimester.
Anti-cancer Activity of Human Gastrointestinal Bacteria
Authors: Quazi Sameer
Published: December 2021

Malignant neoplasm is one of the most incurable diseases among inflammatory diseases. Researchers have been studying for decades to win over this lethal disease and provide the light of hope to humankind. The gastrointestinal bacteria of human hold a complex ecosystem and maintain homeostasis. One hundred trillion microbes are residing in the gastrointestinal tract of human. Disturbances in the microbiota of human’s gastrointestinal tract can create immune response against inflammation and also can develop diseases , including cancer. The bacteria of the gastrointestinal tract of human, can secrete a variety of metabolites and bioproducts which aid in the preservation of homeostasis in the host and gut. During pathogenic dysbiosis, on the other hand, numerous microbiota subpopulations may increase and create excessive levels of toxins, which can cause inflammation and cancer. Furthermore, the immune system of host and the epithelium cell can be influenced by gut microbiota. Probiotics, which are bacteria that live in the gut, have been protected against tumor formation. Probiotics are now studied to see if they can help fight dysbiosis in cancer patients undergoing chemotherapy or radiotherapy because of their capacity to maintain gut homeostasis. Countless numbers of gut bacteria have demonstrated anti-cancer efficiency in cancer treatment, prevention, and boosting the efficiency of immunotherapy. The review article has briefly explained the anti-cancer immunity of gut microbes and their application in treating a variety of cancer. This review paper also highlights the pre-clinical studies of probiotics against cancer and the completed and ongoing clinical trials on cancers with the two most common and highly effective probiotics Lactobacillus and Bacillus spp.

Published: December 2021

The Romani are the main European ethnic minority. The Romani people’s situation of social vulnerability and their difficulties in accessing the health system, make their health indicators worse than those of the non-Romani population. The present study will delve into the health beliefs and experiences with health services and their professionals through the perspectives of Romani women. In this qualitative study, 16 women of different ages were interviewed in a city located in the South of Spain. Four themes emerged from the analysis of data: the construction of the identity of Romani women, difficulties in life, health and disease beliefs and barriers in the access to the health system. We conclude that every project for the improvement of the health of the Romani community must take into account the active participation of Romani women and must consider the principles of Cultural Safety, by delving into the intercultural training of health professionals and addressing the social determinants of health which affect the Romani collective.

In the subcratonic mantle beneath Leningrad pipe, West Ukukit field, Yakutia garnet thermoba-rometry give division to 7 horizons (paleosubduction slabs). Cr-bearing amphiboles >500 reveal a broad range changing from Cr- pargasitic hornblendes to pargasites, edinites, kataforites, К-richterites with increasing pressure determined with new amphibole thermobarometer. Cr-hornblendes compiles the high-temperature branch from 3.5 GPa to Moho for basaltic melt. Amphiboles in the middle eddinites and high-pressure interval reveal different PT ranges from 35 to 40 mw/m2. Richterites near the lithosphere base both trace low –T and convective branches. The amphiboles reveal the 9 geochemical groups. The low-temperature varieties reveal Eu minima and U, Ba, Sr peaks high LILE, Sr, Rb and troughs in Nb, Pb. While high –T varieties have no Eu dips and reveal higher HFSE. Clinopyroxenes and garnets show variable trace ele-ment patterns and divisions in groups eth the plume and subduction signs. The contrasting be-haviour of Ta and Nb is regulated by the rutile partition coefficients likely for primary eclogites. Subduction and Na and K (siliceous) types of fluids percolated through the mantle with abun-dant eclogites causing amphibolization at the different levels of the mantle column. The plume melts produced hybridism and more smooth trace element patterns in reacted minerals, clino-pyroxene. monomineral thermobarometry.

Mandibular advancement devices (MAD) are an effective alternative treatment to CPAP. However, different maneuvers have been performed during the performance of drug sleep-induced endoscopy (DISE) to mimic the effect of MAD. Using the Selector Avance Mandibular (SAM) device, we aimed to identify MAD candidates during DISE using a titratable, reproducible, and measurable maneuver. This DISE-SAM protocol may help to find the relationship between the severity of the respiratory disorder and the degree of response, and to determine the advancement required to improve the collapsibility of the upper airway. Explorations were performed in 161 patients (132 males; 29 females) with a mean age of 46.81 (SD = 11.42) years, a BMI of 27.90 (SD = 4.19) kg/m2 and a mean AHI of 26.51 (SD = 21.23). Results showed no relationship between severity and MAD recommendation. Also, there was a weak positive relationship between the advancement required to obtain a response and the disease severity. Using the DISE-SAM protocol, the response and the range of mandibular protrusion were assessed, avoiding the inter-examiner bias of the jaw thrust maneuver. We suggest prescribing MAD as a single, alternative, or multiple treatment approaches following the SAM recommendations in a personalized design.

Investing in irrigation is very important and strategic in the context of water supply for agriculture. Therefore, this study aims to identify the most efficient irrigation technique and type of fertilizer to maximize the yield of tomatoes (Solanum lycopersicum) in Alfisols. This study was a greenhouse pot experiment with a factorial completely randomized design with two factors consisting of four irrigation techniques (pottery, drip, 75% ETc manual, and 100% ETc manual) and types of fertilizers (without, organic, inorganic, mixed fertilizer). The results showed that pottery irrigation had the highest Nitrogen content in the soil and saved up to 50% water compared to 100% ETc. On the other hand, drip irrigation uses water of 75% ETc with similar plant yield results. The pottery irrigation was the most efficient irrigation method for growing tomato than 75% ETc manual irrigation, and 100% ETc manual irrigation with mixed fertilizers (I4P3) was the highest on tomato yield.

Published: December 2021

Applications architecture is the baseline of any organizational activity, which main goal is to provide the executional environment for businessprocesses in order to deliver products or services to satisfy customer needs and generate revenue. Nowadays, large software engineering projectsalways begin with the architecture design phase, despite the waterfall or agile methodology is used by a software development team. Applicationsarchitecture design is the most important and, at the same time, error-prone stage of the whole software engineering project. It is well-known thatdesign shortcomings made on the design phase may increase drastically to testing and maintenance phases. Further costs to defects fixing may behundred times higher in the later project stages in compare to the design stage on which applications architecture is defined. Common system designsolutions, which were proven on practice and used in many projects, are known as architectural patterns. Software architecture patterns are consideredas building block for system implementation. The most popular and efficient way to share architectural patterns are graphical models that used as anyother blueprints of engineering solutions. Applications architecture models are built to represent system design, whereas, such models are alreadybased on certain patterns as the industry best practices. Hence, in this paper we consider a relevant problem of applications architecture modelsanalysis, which relevance is defined by those fact that designed blueprints of information systems and other software solutions should be carefullychecked for all presumable inefficiencies in order to avoid extra efforts and related costs for defects fixing in the later project stages. It is proposed touse ArchiMate enterprise architecture modeling language, since it can be used not only to represent applications architecture, but is connection tobusiness and technology layers. In order to evaluate applications architecture models, respective ArchiMate metamodel is considered and representedas labeled directed graph, and coupling software metric is selected for analysis. Sample calculations are demonstrated, obtained results are discussed,conclusion and future work directions are formulated.
DISSIPATIVE OSCILLATORS’ POWER CHARACTERISTIC NON-SYMMETRY DYNAMIC EFFECT
Authors: Olshanskiy Vasiliy , Olshanskiy Stanislav
Published: December 2021

The features of motion of a non-linear oscillator under the instantaneous force pulse loading are studied. The elastic characteristic of the oscillator is given by a polygonal chain consisting of two linear segments. The focus of the paper is on the influence of the dissipative forces on the possibility of occurrence of the elastic characteristic non-symmetry dynamic effect, studied previously without taking into account the influence of these forces. Four types of drag forces are considered, namely linear viscous friction, Coulomb dry friction, position friction, and quadratic viscous resistance. For the cases of linear viscous friction and Coulomb dry friction the analytical solutions of the differential equation of oscillations are found by the fitting method and the formulae for computing the swings are derived. The conditions on the parameters of the problem are determined for which the elastic characteristic non-symmetry dynamic effect occurs in the system. The conditions for the effect to occur in the system with the position friction are derived from the energy relations without solving the differential equation of motion. In the case of quadratic viscous friction the first integral of the differential equation of motion is given by the Lambert function of either positive or negative argument depending on the value of the initial velocity. The elastic characteristic non-symmetry dynamic effect is shown to occur for small initial velocities, whereas it is absent from the system when the initial velocities are sufficiently large. The values of the Lambert function are proposed to be computed by either linear interpolation of the known data or approximation of the Lambert function by elementary functions using asymptotic formulae which approximation error is less than 1%. The theoretical study presented in the paper is followed up by computational examples. The results of the computations by the formulae proposed in the paper are shown to be in perfect agreement with the results of numerical integration of the differential equation of motion of the oscillator using a computer.

Soil potential bacteria had been isolated from three sources, including rhizosphere soil samples (rice, oil palm, eggplant, corn), rotten fruit samples (cocoa, oil palm, water), and insect samples (fireworms, locusts, dung beetles, butterflies) taken from Dramaga area with the purposive sampling method. Stages of laboratory study include isolation of bacterial isolates, pathogenicity tests, gram staining, colony morphology observation, toxicity test, biochemical test, and viability test. Two strains that have potential as biocontrol agents with a high ability to kill pests in the second stage of toxicity testing are IRJ 10 (90% mortality rate) and ISU 4 (100% mortality rate). Both of these isolates are members of the genus Bacillus. The highest number of viability was found in zeolite carriers. The number of bacterial cells in the three-week storage period is still above 108 CFU/g.

Rice straw was fractionated with nitric acid in order to avoid the cooking liquor recovery in pulp production from agricultural residue (rice straw). The rice straw treated with 11.03% nitric acid at 90 ℃ for 3hr yields 53.09% pulp. The nitric acid treated rice straw pulp had high amount of lignin and minerals. However, further treatment of nitric acid pulp with low potassium hydroxide reduced the lignin and ash sufficiently as well as the pulp yield. Pulp yield reduced from 53.09 to 34.27%. The papermaking properties of the nitric acid followed by KOH treated pulp showed better quality than the nitric acid pulp. Nitric acid liquor was used several times. Pulp yield decreased in every step of reusing of the nitric acid spent liquor although residual lignin content increased. The final effluent liquor was rich with potassium, nitrogen and biomass that can be used as soil nutrient for cultivation.

ObjectiveIn recent years, cell therapy has become a new research direction in the treatment of diabetes. However, the underlying molecular mechanisms of mesenchymal stem cells (MSCs) participate in such treatment has not been clarified. MethodsIn this study, human umbilical cord mesenchymal stem cells (HUC-MSCs) isolated from newborns were progressively induced into insulin-producing cells (IPCs) using small molecules. HUC-MSCs (S0) and four induced stage (S1-S4) samples were prepared. We then performed transcriptome sequencing experiments to obtain the dynamic expression profiles of both mRNAs and long noncoding RNAs (lncRNAs). ResultsWe found that the number of differentially expressed lncRNAs and mRNAs showed a decreasing trend during differentiation. Gene Ontology (GO) analysis showed that the target genes of differentially expressed lncRNAs were associated with translation, cell adhesion, and cell connection. Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis revealed that the NF-KB signaling pathway, MAPK signaling pathway, HIPPO signaling pathway, PI3K-Akt signaling pathway, and p53 signaling pathway were enriched in these differentially expressed lncRNA-targeting genes. We also found that the coexpression of the lncRNA: CTBP1-AS2 with the PROX1, and the lncRNAs AC009014.3 and GS1-72M22.1 with the mRNA JARID2 was related to the development of pancreatic beta cells. Moreover, the coexpression of the lncRNAs :XLOC_ 050969, LINC00883, XLOC_050981, XLOC_050925, MAP3K14- AS1, RP11-148K1.12, and CTD2020K17.3 with p53, regulated insulin secretion by pancreatic beta cells.ConclusionThis research revealed that HUC-MSCs combined with small molecule compounds were successfully induced into IPCs. Differentially expressed lncRNAs may regulate the insulin secretion of pancreatic beta cells by regulating multiple signaling pathways. The lncRNAs: AC009014.3,Gs1-72m21.1 and CTBP1-AS2 may be involved in the development of pancreatic beta cells, and the lncRNAs: XLOC_050969, LINC00883, XLOC_050981, XLOC_050925, MAP3K14-AS1, RP11-148K1.12, and CTD2020K17.3 may be involved in regulating the insulin secretion of pancreatic beta cells, thus providing a lncRNA catalog for future research regarding the mechanism of the transdifferentiation of HUC-MSCs into IPCs. It also provides a new theoretical basis for the transplantation of insulin-producing cells into diabetic patients in the future.

Purpose: This study was to investigate the clinical efficacy of tapentadol extended-release (ER) on pain control and the quality of life of patients with moderate to severe chronic cancer pain in clinical practice in Korea.Methods: In this prospective, open-label, multicenter trial, patients with sustained cancer pain as well as chronic pain, using or not using other analgesics were enrolled. Thirteen centers recorded a total of 752 patients, during the 6-month observation period, based on the tapentadol ER dose and tolerability, prior and concomitant analgesic treatment, pain intensity, type of pain, adverse effects, and clinical global impression change (CGI-C). A total of 752 patients were screened, 688 were enrolled, and 650 completed the study for efficacy and adverse drug reactions; among them 349 were cancer patients.Results: In total, 752 patients were screened, 688 were enrolled and 650 were completed the study for efficacy and adverse drug reactions, 349 of whom were cancer patients. Tapentadol ER significantly reduced the mean pain intensity including neuropathic pain during the observation period by 2.9 points (from a mean 7±0.87 to 4.1±2.02). Furthermore, the quality of life was observed to be significantly improved based on an objective observation, such as the CGI-C.Conclusion: This study showed that tapentadol ER was effective in patients with moderate to severe cancer pain and was also effective in neuropathic pain, and therefore it significantly improved the patients’ quality of life.

Objectives

To determine the impact of the Coronavirus disease-2019 (COVID-19) pandemic on the length of stay (LOS) and prognosis of patients in the emergency department (ED).
Methods

A retrospective review of case data of patients in the ED during the early stages of the COVID-19 pandemic in the First Affiliated Hospital of Soochow University (January 15, 2020– January 14, 2021) was performed and compared with that during the pre-COVID-19 period (January 15, 2019 – January 14, 2020). Patient information including age, sex, length of stay, and death was collected. Wilcoxon Rank sum test was utilized to compare the difference in LOS between the two cohorts. Chi-Squared test was utilized to analyze the prognosis of patients. The LOS and prognosis in different departments (emergency internal medicine, emergency surgery, emergency neurology, and other departments) were further analyzed.
Results

Of the total 8278 patients, 4159 (50.24%) were ordered in the COVID-19 pandemic group and 4119 (49.76%) were ordered in the pre-COVID-19 group. The length of stay prolongs significantly in the COVID-19 group compared with that in the pre-COVID-19 group(13h vs 9.8h; p < 0.001). There was no significant difference in mortality between the two cohorts (4.8% VS 5.3%; p=0.341).
Conclusion

The COVID-19 pandemic was associated with a significant increase in the length of stay, which may lead to emergency department crowding. And the influence of the COVID-19 pandemic on patients in different emergency departments is different. There is no significant impact on the LOS of emergency neuropathy. Across departments, COVID-19 didn’t have a significant impact on the prognosis of ED patients.
