Bioassay-Guided Isolation and Antioxidant Evaluation of Rutin from Leaf of Polyalthia longifolia

Medicinal plants are sources of antioxidant compounds that have been reported to protect the human body from the adverse effects of free radicals. Therefore, the present study was intended to identify the DPPH (2, 2-diphenyl-1-picrylhydrazyl) free-radical scavenging constituent from the methanol extract of Polyalthia longifolia leaf using bioassay-guided fractionation. On the basis of DPPH radical scavenging assay-guided isolation, the leaf extract of P. longifolia was separated by employing a solvent partition of methanol leaf extract followed by Medium Pressure Liquid Chromatography (MPLC) and High-Performance Liquid Chromatography (HPLC) fractionation. The ethyl acetate fraction (EtOAc) revealed a strong antioxidant activity, compared to other fractions through in vitro DPPH radical-scavenging assay. The repeated fractionation of active EtOAc by MPLC separation and elution procedure yielded a sub-fraction EtOAc_F007 with strong antioxidant potential. The results indicated that the ethyl acetate sub-fraction EtOAc_F007 has noticeable effects on DPPH radical compared with other sub fractions. The sub fraction EtOAc_F007 was further purified using a preparative HPLC system. Subsequent Liquid Chromatography-Tandem Mass Spectrometry (LC-MS/MS) analysis of the purified constituent from sub-fraction EtOAc-F007 led to the identification of rutin as the antioxidant agent in P. longifolia leaf extract. The results obtained suggested that extracts from P. longifolia leaf have potential use as a bioactive source of natural antioxidants by contributing valuable health effects.
Serine protease from Indian Cobra venom: its anticoagulant property and effect on human fibrinogen

Abstract An unusual low molecular weight serine protease (NnP28) has been purified from Indian Cobra (Naja naja) venom from the western region of the Indian sub-continent. We reported the purification and characterization of low molecular NnP28, emphasizing its role on human fibrinogen and anticoagulant property. NnP28 was purified using gel filtration column chromatography followed by ion exchange chromatography. Protein gel electrophoresis revealed its molecular weight ≈28 kDa. The exact molecular mass of NnP28 was found to be 27.12 kDa by mass spectrometry, hydrolyzing casein specifically, inhibited by PMSF suggesting it has a serine protease. NnP28 prolonged the clotting time of re-calcified human citrated plasma and activated partial thromboplastin time (APTT) exhibiting anticoagulant property. NnP28 exhibited fibrinogenolytic activity. Thus, the present study demonstrates the presence of unusual low molecular weight serine protease, emphasizing its importance of region-specific Indian cobra species.
Property, Citizenship, and Invisible Dispossession in Myanmar’s Urban Frontier

ABSTRACT Myanmar’s systematic dispossession of religious and ethnic minorities is well-documented as a tool for counterinsurgency through territorialisation. However, the specific contours of the relationship between minorities, territorialisation, and urban dispossession remain underexplored. The article argues that legislative changes linking identity, property, and belonging led to widescale invisible dispossession of minorities, through the mechanisms of law, citizenship and bureaucracy. Such dispossession gave birth to multiple urban frontiers – temporal spaces that break down existing property relations and create new ones through territorialisation. This article explores one such moment in Myanmar’s largest city and former capital, Yangon, through the lens of Islamic pious endowments, or waqf. By positioning Yangon’s post-1988 landscape as an urban frontier, the article shows how legislative changes serve to actively create frontiers in urban centres through legal dispossession and the transformation of property relations. The article develops the concept of the urban frontier as inextricably tied to territorialisation and dispossession, positing that a frontier, as a spatialized moment in time, can exist at geographical centres as well as peripheries.
Epidemiological and clinical profile of snakebite patients: a retrospective analysis at a tertiary care teaching hospital of southern Rajasthan, India

Background: Snakebite - a global public health problem can be a traumatic experience for patients. They may develop local pain and swelling at the site with or without systemic involvement (haematological and neurological) and at times complications depending upon nature of snake. The present study was planned to determine the epidemiological and clinical profile of snakebite patients at a tertiary care teaching hospital of southern Rajasthan, India.Methods: This retrospective observational study was carried out at a tertiary care teaching hospital only after approval from institutional ethics committee. The data of patients aged between 18-80 years of either gender that had presented with a history of snakebite and admitted to the intensive care unit (ICU) in past 3 years were included. Data related to epidemiological, clinical and investigational parameters was collected and analysed. Data was presented as number (percentage) or mean ± standard deviation.Results: Total 80 patients were analyzed. Male:female ratio was 1.67:1 and mean age of study population was 33.91±14.34 years. Maximum 71 (89%) patients belonged to rural region. Only 16 (20%) patients complained of local pain. Bleeding was noted in 5 (6.25%) patients whereas 36 (45%) patients had ptosis. Prolonged coagulation markers were reported in 35 (44%) patients. Only 2 (2.5%) patients had acute kidney injury. Altered liver and renal function tests were noted in 71 (89%) and 63 (79%) patients respectively. Mechanical ventilation was required in 27 (34%) patients.Conclusions: Young adult males and rural population were prone to snakebites. Local and systemic manifestations were noted in relatively lesser patients compared to the published data. Only fewer patients in I.C. U. required mechanical ventilation.
Improving the performance of water-based drilling fluid using amino acid-modified graphene oxide nanocomposite as a promising additive

It is possible to take advantage of nanomaterials' properties to improve water-based drilling fluids' flux and physical properties. In this paper, glycine methyl ester hydrochloride was synthesized, and the chemical structure was verified to be used as a surface modifier of graphene oxide. At the same time, graphene oxide was prepared from graphite and chlorinated with thionyl chloride, and a nucleophilic substitution reaction was performed to increase the hydrophilicity of graphene oxide. FTIR, Raman, HRTEM, and XRD techniques have identified the prepared and obtained materials from chlorinated graphene oxide's reaction with glycine methyl ester hydrochloride. The glycine-modified graphene oxide (GO) was evaluated as drilling-fluid additives at different concentrations (2.66%, 5.32%, and 10.64%) to enhancement the thermal stability of water-based drilling fluid and reducing the filtration loss. The obtained results confirmed that the successful glycine-modified graphene oxide/bentonite to enhance both thermal stability (up to 350 °F) and filtration loss.
The Impact of Belt and Road Initiative on Regional Financial Integration – Empirical Evidence from Bond and Money Markets in Belt and Road Countries

Abstract Belt and Road Initiative (BRI) proposed in 2013 has received wide research attention in recent years. However, rigorous quantitative studies on BRI’s impact on regional financial integration are scarce. This paper contributes to filling this research gap by adopting Adam et al. beta convergence and sigma convergence method. Two processes of financial integration are of primarily concern i.e. intraregional integration and the integration with the Chinese markets. Four regions are specifically investigated: Central and East Europe, Southeast Asia, Common Wealth Independent States and Africa. The findings indicate that: (1) BRI mainly influences the tendency of financial integration while the degree of integration was merely influenced. (2) Integration process in bond and money markets behave differently toward BRI with the tendency of bond market integration being stronger. (3) Four regions exhibited ununiformed response to BRI in terms of financial integration. This paper also discussed BRI and the values it brings to incorporate financial integration and sustainable development practices to the BRI regions. Examples of BRI projects prove the importance of BRI and regional sustainable economic development. To enhance the sustainability of BRI projects, this paper recommends further studies to examine the dynamics and interlinked relationships of the BRI regions.
Design Focus Group as a Controlled-Experiment Setting

This paper argues the flexibility of focus group in Design research as a controlled-experiment setting to study Designerly Intuition at concept-stage decision making. This paper outlines the focus group design in terms of the types and structure considerations and the moderator factor. Finally, the focus-group result gathers dual-mode input from novice Industrial Designers (1) 'as a group' and the intuitive attributes as (2) ‘individual participants’. Therefore, the focus group design for the data collection setting is established through the research layout and space design that accommodates both modes of inquiry.

Numerical study on the mechanical behavior of ultrahigh performance concrete using a three‐phase discrete element model

This paper deals with numerical analysis on the mechanical behavior of ultrahigh performance concrete (UHPC) under uniaxial compression. For the modeling of the mechanical behavior of UHPC, the mesh‐free discrete element method was applied. To calibrate the model parameters and validate the numerical simulation results, a set of experimental investigations including mechanical tests, microscopy and tomography analysis, were performed. The scanning electron microscopy and polarized light microscopy were used to examine cross sections of UHPC as well as to characterize interfacial transition zone and aggregate in detail. X‐ray microtomography analysis was used to obtain information about the nonspherical shape of aggregate and to generate a realistic structural model. Simulation results have shown that the developed model predict stiffness reliably, strength, and breakage pattern of UHPC and shows good agreement with experimental results. Finally, the model has been applied to analyze the main crack initiation in static failure and to investigate the influence of different parameters such as aggregate content as well as aggregate and binder stiffness on the mechanical behavior of UHPC.
Embracing proving into everyday lesson by problem posing

Proof plays significant roles in the context of school mathematics and is a tool for enhancing student’s understanding of mathematics. Lack of opportunities for proving in textbook has been documented. This study was conducted to consider an instructional way to make proving as everyday lesson by formulating more opportunities than did textbooks. The guiding assumption of this study is that conjectures which students come up with can be initiatives for learning how to prove. This preliminary study will show that problem posing is a strategic tool with potential to bridge everyday instruction and the practice of proving so as to teach how to prove more meaningfully and authentically.

Psychometrics, Rhetoric, Narrative in Media Psycholinguistics

The paper is focused on the critical exploration of an experiment held in the Ukrainian media environment. Results of the experiment are reflected in the book Freedom of Speech Against Fear and Humiliation . published by Savik Shuster, the Ukrainian political journalist and the Freedom of Speech TV talk show host. The study aims to define factors and predictors of the Ukrainian audience’s social behavior. In this regard, narrative, conversational, and intent analyses of his talk shows participants’ conflict interaction described in the book, were applied. These tools made it possible to explicate his narratives’ main topics, their prominence, role positions, archetypal patterns of the participant and host’s behavior. The narrative structure of “negative” scenarios of the talk shows described in the book enabled defining the host as the encourager of the speakers’ conflict behavior, high tension of their discourse that leads to deconstructing, discrediting, and demonizing the opponent’s political party image. Although S. Schuster's conclusions were full of dramatic statements and almost apocalyptic predictions, their reinterpretation was necessary. The application of F-test as a measure of testing statistical hypotheses relevant to empirical data, allowed to search for additional political and psychological explanatory models of the “emotional map of Ukraine”. Results of the study demonstrate hidden suggestion of hopelessness, feelings of betrayal, inspiration of protest moods,inspired by the speakers invited to the TV show. This adversely affects the critical understanding of current social processes along with radicalization of public sentiment by shifting the locus of control to the outside, when the audience invited to the show delegates responsibility for the state of affairs in the country and their own well-being to their political leaders.

Deep Wide Spatial-Temporal Based Transformer Networks Modeling for the Next Destination According to the Taxi Driver Behavior Prediction

This paper uses a neural network approach transformer of taxi driver behavior to predict the next destination with geographical factors. The problem of predicting the next destination is a well-studied application of human mobility, for reducing traffic congestion and optimizing the electronic dispatching system’s performance. According to the Intelligent Transport System (ITS), this kind of task is usually modeled as a multi-class problem. We propose the novel model Deep Wide Spatial-Temporal-Based Transformer Networks (DWSTTNs). In our approach, the encoder and decoder are the transformer’s primary units; with the help of Location-Based Social Networks (LBSN), we encode the geographical information based on visited semantic locations. In particular, we trained our model for the exact longitude and latitude coordinates to predict the next destination. The benefit in the real world of this kind of research is to reduce the customer waiting time for a ride and driver waiting time to pick up a customer. Taxi companies can also optimize their management to improve their company’s service, while urban transport planner can use this information to better plan the urban traffic. We conducted extensive experiments on two real-word datasets, Porto and Manhattan, and the performance was improved compared to the previous models.
Prevalence of Gingival Hyperplasia Induced by Anticonvulsants: A Systematic Review

Objective: Gingival hyperplasia (GH) is one of the side effects of anticonvulsant drugs. The aim of this study was to verify the prevalence of GH associated with the use of anticonvulsant, through a systematic review. Material and Methods: Systematic search was done at databases Pubmed and Embase between January 1984 and March of 2020 for identification of articles addressing the prevalence of GH associated with the use of anticonvulsant drugs. The methodological index for non-randomized studies (MINORS) was independently assessed for quality in the selected papers. Results: The search identified 4.471 references. Nine articles were selected and evaluated 632 participants. All of the studies included in the systematic review showed a low risk of bias. The anticonvulsants used by patients were carbamazepine, ethosuximide, phenytoin, primidone, phenobarbital, sodium valproate. The studies showed a correlation between different types of anticonvulsants and GH prevalence, with a range from 0% to 73%. Among the anticonvulsants used, phenytoin showed the greatest incidence of GH, varying between 15.61% and 73% in patients. Conclusion: In the analysis of the results obtained in the literature, it is possible to notice that the great majority of studies presented incidence of GH associated with anticonvulsant use. However, further studies are necessary to understand the anticonvulsant action mechanism inducing GH, as well as the prevention forms, given that GH is a significant side effect.

Body Image In Teenage Girls

The study examined the peculiarities of Russian girls’ body image. Participants included 136 Russian teenage (13-15). All the girls already got menarches. To obtain the data used questionnaire and projective measures. Results indicated that teenage girls demonstrate «normative discontent» with the body. Most teenage girls aged 13-15 are characterized by a low degree of body acceptance, and by a significant gap between the images of a real and ideal body. Teenagers’ self-respect and self-incrimination depend on positivity / negativity of the body image. Functional characteristics of the body and positive body image are connected both with external and internal standards of teenage girls. Correlation analysis of body image parameters with body mass index (BMI) showed that there were negative correlations of degree of compliance with external standards and assessment of physique with data of display (-0.34 and -0.40, respectively, p ≤ 0.01). At the same time, the relationship of BMI and compliance of the body with girls' own internal standards of a teenager girl was not revealed. About 40% of adolescent girls had a negative body image, 30% of the girls had a positive one, and the rest had an ambivalent one. Belonging to a particular group did not depend on BMI. 2672-815X © 2020 Published by European Publisher.
Minimal Monitoring of Improvements in Energy Performance after Envelope Renovation in Subsidized Single Family Housing in Madrid

This study quantified the improvement in energy efficiency following passive renovation of the thermal envelope in highly inefficient residential complexes on the outskirts of the city of Madrid. A case study was conducted of a single-family terrace housing, representative of the smallest size subsidized dwellings built in Spain for workers in the nineteen fifties and sixties. Two units of similar characteristics, one in its original state and the other renovated, were analyzed in detail against their urban setting with an experimental method proposed hereunder for simplified, minimal monitoring. The dwellings were compared on the grounds of indoor environment quality parameters recorded over a period covering both winter and summer months. That information was supplemented with an analysis of the energy consumption metered. The result was a low-cost, reasonably accurate measure of the improvements gained in the renovated unit. The monitoring output data were entered in a theoretical energy efficiency model for the entire neighborhood to obtain an estimate of the potential for energy savings if the entire urban complex were renovated.
Saudi bride-to-be consumption: Negotiation between traditional and idiosyncratic meanings

In Saudi Arabia, brides are traditionally required to shop for the wedding day, several social events prior to the wedding, and the new life after the wedding. The purpose of this study was to explore how Saudi brides-to-be negotiate cultural influences as they make their purchase decisions. Qualitative data were collected via in-depth interviews with 14 Saudi women who were engaged to be married. Data were analyzed using constant comparison processes. Analysis revealed three themes, including: (a) new purchases portray aspects of bride-to-be’s individuality, (b) others’ influence on brides-to-be’s purchase decisions, and (c) perception of tradition. Saudi brides-to-be had to consider numerous influencers from significant and generalized others while negotiating details of the wedding celebration events. This led them to become uncertain of how to present various aspects of the self: their old self, new self in role of bride, and individuality within consideration of the traditions. <! -- /* Font Definitions */ @font-face{font-family:"Cambria Math";panose-1:2 4 5 3 5 4 6 3 2 4;mso-font-charset:0;mso-generic-font-family:roman;mso-font-pitch:variable;mso-font-signature:-536870145 1107305727 0 0 415 0;}@font-face{font-family:Calibri;panose-1:2 15 5 2 2 2 4 3 2 4;mso-font-charset:0;mso-generic-font-family:swiss;mso-font-pitch:variable;mso-font-signature:-1610611985 1073750139 0 0 159 0;} /* Style Definitions */ p.MsoNormal, li.MsoNormal, div.MsoNormal{mso-style-unhide:no;mso-style-qformat:yes;mso-style-parent:"";margin-top:0in;margin-right:0in;margin-bottom:10.0pt;margin-left:0in;line-height:115%;mso-pagination:widow-orphan;font-size:11.0pt;font-family:"Calibri",sans-serif;mso-ascii-font-family:Calibri;mso-ascii-theme-font:minor-latin;mso-fareast-font-family:Calibri;mso-fareast-theme-font:minor-latin;mso-hansi-font-family:Calibri;mso-hansi-theme-font:minor-latin;mso-bidi-font-family:Arial;mso-bidi-theme-font:minor-bidi;}p.Default, li.Default, div.Default{mso-style-name:Default;mso-style-unhide:no;mso-style-parent:"";margin:0in;mso-pagination:widow-orphan;mso-layout-grid-align:none;text-autospace:none;font-size:12.0pt;font-family:"Times New Roman",serif;mso-fareast-font-family:Calibri;mso-fareast-theme-font:minor-latin;color:black;}.
