Osteomalacia is a bone-demineralizing disease of adulthood, often caused by hypovitaminosis D. Current animal models of the disease mimic osteomalacia as a consequence of gastric bypass or toxic exposure to metals, but a relevant model of diet-induced osteomalacia is lacking. For that purpose, 7-month-old female Sprague Dawley rats were randomly assigned into 2 weight-stratified groups and maintained for 4 months on synthetic diets containing negligible or normal levels of vitamin D. The dietary regimen resulted in vitamin D deficiency as measured by 25-hydroxyvitamin D serum levels; however, hypovitaminosis D per se did not affect biomarkers of calcium metabolism and bone turnover, nor did it result in increased osteoid. Thus, vitamin D depletion through the diet was found to be insufficient to induce an osteomalacia-like phenotype in the adult rat. After 4 months, the phosphate content of the vitamin D–depleted diet had decreased to 0.16% (calcium:phosphorus ratio of 5.85), resulting in an osteomalacic-like condition (trabecular osteoid surface/bone surface constituted 33%; CI, 26-40). The diet change also affected both metabolic and bone turnover biomarkers, including significantly suppressing serum fibroblast growth factor 23. Furthermore, decreased dietary phosphate in a vitamin D–depleted diet led to microarchitectural changes of trabecular and cortical bone, lower bone mass density, lower bone mass content and decreased bone strength, all indicating reduced bone quality. Taken together, our results show that osteomalacia can be induced in the adult female rat by depleting vitamin D and lowering phosphate content in the diet.

Published: June 2020

The contiguous gene deletion syndrome of congenital adrenal hyperplasia and Ehlers-Danlos syndrome, named CAH-X, is a rare entity that occurs because of a deletion of a chromosomal area containing 2 neighboring genes, TNXB and CYP21A. Here, we describe a patient from a consanguineous family in which coincidentally MEN-1 syndrome is associated with CAH-X, causing particular challenges explaining the phenotypic features of the patient. A 33-year-old man with salt-wasting congenital adrenal hyperplasia and classic-like Ehlers-Danlos syndrome presented with an adrenal crisis with a history of recurrent hypoglycemia, abdominal pain, and vomiting. He was found to have primary hyperparathyroidism, hyperprolactinemia, and pancreatic neuroendocrine tumors, as well as primary hypogonadism, large adrenal myelolipomas, and low bone mineral density. A bladder diverticulum was incidentally found. Genetic analysis revealed a heterozygous previously well-described MEN1 mutation (c.784-9G > A), a homozygous complete deletion of CYP21A2 (c.1-?_1488+? del), as well as a large deletion of the neighboring TNXB gene (c.11381-?_11524+?). The deletion includes the complete CYP21A2 gene and exons 35 through 44 of the TNXB gene. CGH array found 12% homozygosity over the whole genome. This rare case illustrates a complex clinical scenario with some initial diagnostic challenges.
“A World of Tomorrow”: Trauma, Urbicide, and Documentation in A Woman in Berlin: Eight Weeks in the Conquered City
Authors: Cornish Sarah E.
Published: June 2020

The World War II diary A Woman in Berlin: Eight Weeks in the Conquered City (2005) documents one woman’s story of survival in the spring of 1945 in Berlin, during which upward of 130,000 women were raped by soldiers of the Red Army. First, this essay introduces the politics of recuperating the English translation of the diary within the context of the scant supporting historical documentation and memorialization of Berliner women’s experience during the occupation. Second, it demonstrates how the diary produces a feminist account of survival and a narrative for collective trauma by examining the diarist’s representations of the effects of rape and rubblestrewn Berlin. Third, the essay details the complicated publication history of the diary through a consideration of the relationship between the trauma sustained by the survivors of mass rape and the blows to German national identity that it documents.
The Rhubarbarian’s Redress: Tony Harrison and the Politics of Speech
Authors: Fogarty William
Published: June 2020

Taking up the persistent question of poetry’s sociopolitical capacities by considering how Harrison’s poems depend on the power of local speech, this article examines how they cast his working-class northern English dialect in meter and rhyme as a way to scrutinize social hierarchies. Marshaling various forms of speech, including his own vernacular, into traditional patterns of poetry, Harrison interrogates classist notions about nonstandard speech and its relation to that tradition while exploring the disturbances produced by class separation. Where poetry scholarship in general and Harrison scholarship in particular often place demotic registers in opposition to traditional verse forms, this article argues that it is precisely the working relationships Harrison finds between verse forms and speech forms that upend hierarchies in his poetry, making new music out of local parlance.
The Reeducation of Race
Authors: Thakkar Sonali
Published: June 2020

This article traces the emergence of racial plasticity in the discourse of midcentury liberal internationalism and antiracism, focusing on the 1950 Statement on Race by the UN Educational, Scientific, and Cultural Organization (UNESCO). The author argues that the statement is both an important precursor to contemporary celebrations of plasticity and an object lesson in the conceptual and political limitations of plasticity as a response to race and racism. Paying particular attention to the statement’s treatment of plasticity as synonymous with educability, the author argues that plasticity’s centrality to the race concept at midcentury was driven by a pedagogical aspiration to make not just racial ideologies but racial form itself subject to reeducation. In UNESCO’s discourse, plasticity, or the idea that race is changeable and malleable, represents both the promise of freedom from race and a biopolitical imperative. Even as UNESCO sought to dispel the scientific racism it associated most closely with Nazism, the statement’s privileging of plasticity accommodated and extended strategies of colonial racial management. While UNESCO’s antiracism found it easier to imagine an end to race than to imagine that racism could be contested in political terms, anticolonial politics challenged both the colonial ordering of the world and the biopolitical logic of racial plasticity.
Spoken Body
Authors: Charon Rita
Published: June 2020

The linguistic, rhetorical, and metaphorical powers of language profoundly influence events of health care. Physicians are professionalized into their own isolating language at the cost of fluency in their native tongue. Translation is always inadequate. Physicians resort to ironizing detachment from patients to delude themselves that they will not sicken and die. David Foster Wallace’s Infinite Jest and the Wittgensteinian and enactive/embodied cognitive and phenomenological concepts that support his work offer models for clinicians committed to authentic care of patients.
A Structure of Terror in Jamaica Kincaid’sA Small Place
Authors: Shoemaker Lauren E.
Published: June 2020

Literature by women of the third world is capable of expressing emergent feelings attached to objects and everyday activities, which reveal underlying economic processes. One such activity that inspires diverging feelings, the Caribbean vacation, reveals a continued exploitative colonial economy. Jamaica Kincaid’s essays in A Small Place dramatize the competing narratives of vacation as happiness object and misery-causing activities within the framework of the structure of terror. Many critics read differences of race and class developed through figures of the tourist and the native in the early essays as necessarily divisive post-colonial critique, but they read Kincaid’s final essay as an attempt to transcend such divisions. Many have lauded Kincaid’s call to throw off old categories and focus on shared (biological) humanity, yet this very category of “human” has been constructed through (social) discourses of race, gender, and class. Instead, I argue that Kincaid continues insisting on multiple subject positions, subverting the argument she seems to make on the surface and critiquing colonial epistemologies—in discourse and visual regimes—through application of Sylvia Wynter’s interrogation of dominant worldviews of both humanism and an approach to environments.
The Contours of Speaking Out
Authors: Basarudin Azza , Shaikh Khanum
Published: June 2020

This article discusses the vexed relationship between women’s activism, state security, and feminist empowerment by focusing on the Department of Homeland Security’s Countering Violent Extremism (CVE) initiative, a program that seeks to build partnerships between government agencies and Muslim communities to prevent homegrown terrorism. From its inception, CVE has been controversial among Muslim and non-Muslim leaders within Southern California’s civil rights communities. While some suggest that American Muslims must play a leading role in countering domestic terrorism by working with government agencies, others feel that these partnerships are only meant to extend surveillance into Muslim communities. In this article, the authors critically examine how women are incorporated into local counterterrorism measures via CVE to think about the impact of such incorporation on their intimate, familial, and community relationships in the local politics of the War on Terror. The authors are interested in how liberal feminist discourses of motherhood and empowerment are appropriated in the service of national security and how such articulations of feminism domesticate and delink critique from the politics of racial solidarity and empire in the increasingly xenophobic sociopolitical landscape of the United States. Based on ethnographic research in Southern California’s Muslim communities, the authors trace the complex contours of women’s agency and the transnational politics of “Muslim America.” The authors draw on intersectional and anti-imperialist theories, as well as a body of feminist securitization scholarship to think about the ways that women’s activism, communal resistance, and national security are interlinked in the construction of the discourses around counterterrorism and their affiliated policies.
Depression and Anxiety in patients undergoing Percutaneous Coronary Intervention for Acute Coronary Syndrome
Authors: Mujtaba Syed Fayaz , Sial Jawaid Akbar , Karim Musa
Published: June 2020

Background and Objective: Depression and anxiety are very common in patients with cardiac diseases. Percutaneous coronary intervention (PCI) has not only decreased mortality but angina, heart failure and recurrent hospitalization all are improved. Therefore, anxiety and depression associated with fibrinolytic therapy in acute coronary syndrome (ACS) are expected to be decreased in the patient undergoing PCI. Therefore, the aim of this study was to determine prevalence of depression and anxiety in patients undergoing percutaneous coronary intervention for acute coronary syndrome.

Methods: This study was conducted at Larkana Satellite Center of National Institute of Cardiovascular Diseases (NICVD), Pakistan from August 2018 to December 2018. Patients who underwent cardiac intervention within one month were enrolled in this study. Patients were interviewed regarding their basic demographics, indication for intervention and procedure details. Symptoms of anxiety were assessed using the translation of inventory of SAS (Zung’s Self-Rating Anxiety Scale). Patients were interviewed for depression by using Becks depression inventory (BDI).

Results: A total of 153 patients were included in this study out of which 118(77.1%) were males and 35(22.5%) were females. All were married except one. Diabetes mellitus (DM) was present in 61(39.9%), hypertension (HTN) in 69(45.15%), obesity in 15(9.8%), and 40 (26.1%) were smokers. Depression was present in 16 (10.5%) patients and anxiety was present in 12(7.5%) of patients. On analysis of the association of various factor with depression; non-diabetics, housewives, laborers and uneducated were found to be more depressed. While those who smoke or earn more than 50 thousand were found less likely to be depressed.

Conclusion: Both depression and anxiety were present in only 10.5% and 7.5% of the patients after percutaneous coronary intervention for acute coronary syndrome.

Authors: Liu Tangxia , Wang Jing , Li Chunmei , Jia Lingzhi
Published: June 2020

Objective: To analyze the effect of decitabine combined with conventional chemotherapy on myelodysplastic syndrome (MDS) and its influencing factors.

Methods: Eighty patients with MDS who were admitted to our hospital were selected by this study between February 2017 and February 2018. The selected patients were divided into a traditional group (CAG/DA scheme) and the combined group (DAC combined with CAG/DA scheme) according to the random number table method, 40 each. The clinical treatment effects of the two groups were compared, and the influencing factors of the effect were analyzed.

Results: After four courses of treatment, the difference in the total effective rate between the two groups were statistically significant (P<0.05); the difference in the incidence of adverse reactions and in the overall survival (OS) rate between the two groups were not statistically significant (P>0.05). However, the progression free survival (PFS) rate of the combined group was significantly higher compared with the traditional group (P<0.05); the Hb level, WHO stage and and karyotype of the patients before treatment had significant influence on the treatment effect (P<0.05).

Conclusion: DAC in combination with conventional chemotherapy has good effect in the treatment of MDS, and it will not increase adverse reactions. In addition to treatment scheme, the influencing factors of the effect of treatment for MDS also include Hb, WHO stage and karyotype.

Enhanced DBSCAN with Hierarchical Tree for Web Rule Mining
Authors: Gullipalli Neelima , Rodda Sireesha
Published: June 2020

Like other mining, web mining is also necessary to increase the power of web search engine to identify the intended web page and web document. While processing with large datasets, there arises several issues associated with space availability, similarity relationships between different webpage’s and running time. Hence, this paper intends to develop an enhanced web mining model based on two contributions. At first, the hierarchical tree is framed, which produces different categories of the searching queries (different web pages). Next, to hierarchical tree model, enhanced Density-Based Spatial Clustering of Applications with Noise (DBSCAN) technique model is developed by modifying the traditional DBSCAN. This technique results in proper session identification from raw data. Moreover, this technique offers the optimal level of clusters necessitated for hierarchical clustering. After hierarchical clustering, the rule mining is adopted. The traditional rule mining technique is generally based on the frequency; however, this paper intends to enhance the traditional rule mining based on utility factor as the second contribution. Hence the proposed model for web rule mining is termed as Enhanced DBSCAN-based Hierarchical Tree (EDBHT). It benefits in providing the search results depending on high level information (e.g., location), so that the ability of search engine in providing the interesting association rules can be improved. Next, to the implementation, the performance of proposed EDBHT is found to be enhanced when compared over several traditional models.
Artefacts Removal from ECG Signal: Dragonfly Optimization-based Learning Algorithm for Neural Network-enhanced Adaptive Filtering
Authors: Viswanadham Talabattula , P Rajesh Kumar
Published: June 2020

Electrocardiogram (ECG) artefact removal is the major research topic as the pure ECG signals are an essential part of diagnosing heart-related problems. ECG signals are highly prominent to the interaction with the other signals like the Electromyography (EMG), Electroencephalography (EEG), and Electrooculography (EOG) signals and the interference mainly occurs at the time of recording. The removal of the artefacts from the ECG signal is a hectic challenge, for which, a novel algorithm is proposed in this work. The proposed method utilizes the adaptive filter termed as the (Dragonfly optimization + Levenberg Marqueret learning algorithm) DLM-based Nonlinear Autoregressive with eXogenous input (NARX) neural network for the removal of the artefacts from the ECG signals. Once the artefact signal is identified using the adaptive filter, the identified signal is subtracted from the primary signal that is composed of the ECG signal and the artefacts through an adaptive subtraction procedure. The clean signal thus obtained is used for effective diagnosis purposes, and the experimentation performed to prove the effectiveness of the proposed method proves that the proposed method obtained a maximum Signal-to-noise ratio (SNR) of 52.8789 dB, a minimum error of 0.1832, and minimum error of 0.428.
CPU-Memory Aware VM Consolidation for Cloud Data Centers
Authors: Baskaran Nithiya , R Eswari
Published: June 2020

The unbalanced usage of resources in cloud data centers cause an enormous amount of power consumption. The Virtual Machine (VM) consolidation shuts the underutilized hosts and makes the overloaded hosts as normally loaded hosts by selecting appropriate VMs from the hosts and migrates them to other hosts in such a way to reduce the energy consumption and to improve physical resource utilization. Efficient method is needed for VM selection and destination hosts selection (VM placement). In this paper, a CPU-Memory aware VM placement algorithm is proposed for selecting suitable destination host for migration. The VMs are selected using Fuzzy Soft Set (FSS) method VM selection algorithm. The proposed placement algorithm considers both CPU, Memory, and combination of CPU-Memory utilization of VMs on the source host. The proposed method is experimentally compared with several existing selection and placement algorithms and the results show that the proposed consolidation method performs better than existing algorithms in terms of energy efficiency, energy consumption, SLA violation rate, and number of VM migrations.
All-atmosphere IS-MST Radar
Authors: Medvedev Andrey , Potekhin Aleksandr , Setov Artem , Kushnarev Dmitriy , Lebedev Valentin
Published: June 2020

The IS-MST radar, as the name implies, combines two different methods for studying the atmosphere using a backscatter signal. Turbulent fluctuations of the medium cause scattering in the mesosphere—stratosphere—troposphere (MST). In the upper atmosphere, incoherent scatter (IS) appears in ionospheric plasma. Special-purpose instruments have been built before such that measurements in one of these modes were the most effective. MST radars were utilized for studying wave activity in the lower and middle atmosphere; the IS radar, for ionospheric research. Nowadays, however, for a comprehensive investigation of atmospheric phenomena, it is necessary to have an idea of processes in all atmospheric layers and near-Earth space. The radar, which combines capabilities of IS and MST measurements, will be able to cover layers from the troposphere to the plasmosphere and to study processes of energy transfer from the lower and middle atmosphere to the ionosphere as well as the interaction of the magnetosphere with the upper atmosphere. Apart from atmospheric research, the radar will allow us to track spacecraft and space debris, determining precise coordinate characteristics. The antenna system is also suitable for radio astronomical observations. In the paper, we provide justification for the 154–162 MHz frequency range and discuss technical solutions of the IS-MST radar project and basic operating modes. In addition, we estimate radar diagnostic capabilities for different types of measurements.
Fair Trade Software: empowering people, enabling economies
Authors: Were Peres , Madeley Julie , Munsell Mädchen
Published: June 2020

Fair Trade Software (FTS) builds on the principles of conventional Fair Trade and applies them to software services in developing countries. Using a model of Shared Value Creation, FTS leverages reputation enhancement opportunities for companies in OECD countries to encourage them to share knowledge with partners in developing countries. Working in this way has been demonstrated to improve the quality and capacity of software companies in developing countries and generate digital employment for urban youth. The improvement gains can lead to significant improvements in other sectors that rely on digital services, e.g. healthcare and education.
Fair Trade and distant production: the normalisation of the North in book publishing
Authors: Small Audrey
Published: June 2020

This article seeks to articulate some of the major theoretical difficulties raised by associating book publishing with Fair Trade, building on the concept of the ‘distant producer’ as critiqued by both Frank Trentmann and Matthias Zick Varul. Where these scholars examine the framing of the Fair Trade producer as always being based in the global South, this article explores an instance of a ‘distant Northern producer’ of sorts, with particular reference to the publishing of ‘francophone African literature’. The dominance of Northern publishers in this field creates a complex series of ‘normalisations of the North’, in which Paris is normalised as the centre of cultural production; the French language is normalised as the dominant language of culture; and non-print literatures are marginalised in global cultural production. Specific issues concerning intellectual production and property then may be seen as sitting uneasily alongside traditional models and perceptions of Fair Trade.
The ‘burden’ of traceability in gold supply chains
Authors: Finlay David
Published: June 2020

Artisanal and Small-scale Mining (ASM) constitutes 15% (600 tonnes) of global gold production but, as a sector, remains largely veiled to both businesses and consumers in developed Western markets. The movement towards the ‘responsible sourcing’ of such gold is beginning to gain traction, especially in the jewellery sector, but has started some two decades after equivalent movements for responsible coffee, cocoa and tea, and is accompanied by its own - often surprising - challenges. This article provides an overview of both the ASM landscape and the challenges facing miners and supply chain actors in delivering responsibly mined gold to the point of end-consumer products. It concludes with two examples of mass-balance models that Fairtrade is introducing to drive increases in the volumes of responsibly mined gold sold from mine sites, which accounts for and responds to the ‘burden’ of full traceability for both large- and small-scale supply chain actors.
Automatic removal of phase aberration in holographic microscopy for drug sensitivity detection of ovarian cancer cells
Authors: Leiping Che , Xiao Wen , Xiaoping Li , Liu Jinjin , Pan Feng , Ferraro Pietro
Published: June 2020

Real-time and long-term monitoring of the morphological changes of cells in biomedical science is highly desired. Quantitative phase imaging (QPI) obtained by various interferometric methods is the ideal tool for monitoring such processes as it allows to get quantitative information and thus assessing the right response on cell behaviors. Among QPI, digital holography (DH) in microscope configuration is a powerful tool as it is tolerant versus defocusing and for this reason is able to compensate for eventual defocusing effect during long time-lapse recording. Moreover, DH dynamic phase imaging for biological specimens has several advantages, namely non-invasive, label-free, and high-resolution. However, in DH, one of the main limitations is due to the need compensate aberrations due to the optical components in the object beam. In fact, the image of the object is inevitably embedded in aberrations due to the microscope objective (MO) and other optical components in the optical setup. Here, we propose an automatic and robust phase aberration compensation method based on a synthetic difference (SD) image process. The method is able to detect automatically object-free regions. From such regions, hologram’s aberrations can be accurately evaluated and cleaned up in the final QPI maps. Thanks to our method, temporal evolutions of cell morphological parameters were quantitatively analyzed, hence helping in studying the drug sensitivity of ovarian cancer cells. The experimental results demonstrated that the proposed method could robustly separate the object-free region from the distorted phase image and automatically compensate the total aberrations without any manual interventions, extra components, prior knowledge of the object, and optical setup.
Students’ appreciation of journalists’ roles in Cuba, Ecuador and Venezuela
Authors: Calderón Carlos Arcila , Alonso Martín Oller , Pérez Dasniel Olivera
Published: June 2020

The pre-professional journalistic culture of Ecuador, Cuba and Venezuela is studied based on the perception that students of Social Communication and Journalism have about the professional roles of journalists and their motivations, expectations and professional experiences. For this analysis, a total of 1273 students from 21 universities enrolled in Social Communication and Journalism degrees were surveyed during the first semester of 2016 (Ecuador = 500, Venezuela = 390, Cuba = 383). This sample is statistically representative with a confidence level of 95 per cent and a margin of error of maximum 5 per cent. The results indicate that students in Ecuador, Cuba and Venezuela, despite the disparity and polarization of opinions, consider that the role of ‘civic agent/disseminator’ is the one that best fits the main functions of journalists and journalism, without forgetting their critical and patriotic feeling in favour of a social change and national development.
Ill-fitting suits and taped ties: Donald Trump’s politico-sartorial style
Authors: Morrison Kevin A.
Published: June 2020

Because Donald Trump’s language and rhetoric attract so much attention and comment, discussions about the role of fashion and style in the Trump presidency are often limited to outfits worn by the First Lady or his daughter, Ivanka. When Trump’s style is analysed in the press and on social media platforms, it is frequently derided. This article argues for the importance of Donald Trump’s sartorial choices as forms of visual (political) communication. It suggests that Trump, whose appearance and taste are often subject to ridicule in popular culture, has actually cultivated an image of himself as anti-elite. Drawing on Pierre Bourdieu’s lesser-known theory of the corporeal hexis to discuss Trump’s self-presentation, this article shows how, as both candidate and president, he has used sartorial codes to communicate with the different constituencies that were vital to his election and remain central to his bid for re-election in 2020.

The quality of life in water bodies depends on their physico-chemical properties and biodiversity.
These physico-chemical properties are being disturbed by continuous addition of industrial, municipal

Optical properties including band gap of many wide band gap semiconductor oxides like TiO2, ZnO
and SnO2 has limitations over their bare use in photocatalytic applications. Thus, in view of above,
tungsten oxide (WO3), an intermediate band gap metal oxide has been selected to explore for
photocatalytic degradation application. Present work deals with the preparation of WO3 using a simple
chemical solution based spin coating method. The prepared sample has been characterized for structural,
morphological and photocatalytic properties. Degradation experiment of dye was carried out
systematically at the optimized conditions of pH 4 and contact time (120 min) between dye and
catalyst. For optimized conditions, WO3 showed about 75% of degradation of rhodamine-B. This
suggests that a huge scope to optimize preparative parameters for WO3 to explore it as an alternative to
conventional metal oxides.

N2,N6-bis(5-mercapto-1,3,4-thiadiazol-2-yl)pyridine-2,6-dicarboxamide, X= Cl−, CH3COO−) were
synthesized by the reaction of pyridine-2,6-dicarboxylic acid and 2-amino-5-mercepto-1,3,4-thiadiazole.
The synthesized ligand was reacted in THF with metal salts (Cu, Ni and Fe) to form complexes.
Deprotonated ligand shows tridentate nature and coordinate to metal ion to form pincer cavity. In all,
complexes metals were surrounded by three nitrogen atom and other site coordinated by other groups
(chloride, acetate). All the synthesized complexes were characterized by spectroscopic techniques
like UV-visible, 13C NMR and 1HNMR, IR spectroscopy, DSC, elemental analysis and molar
conductance measurements. The ligand and its metal complexes were tested for antimicrobial activity
against bacterial and fungal strains by determining inhibition zone, minimal inhibitory concentration
(MIC) and minimal bactericidal concentration (MBC). The complexes showed moderate antimicrobial
activity and antifungal activity when tested against bacteria and fungi

The report stated that the treatment of o-phenylenediamine with acetone dicarboxylic acid, acetone
and acetophenone afforded 2,4,4-trimethyl-3H-5-hydro-1,5-benzodiazepine. However, direct reactions
of o-phenylenediamine with oximes (acetone oxime, acetophenone oxime, and benzophenone oxime)
as ketone equivalents did not occur. In the course of present investigations, it is found that
dichloroamine-T can be an efficient reagent for the conversion of oximes into the corresponding carbonyl
compounds. As a part of a research program related to the synthetic study of pharmacologically
interesting benzodiazepine compounds, herein the synthesis of 1H-1,5-benzodiazepine derivatives
from heteroaromatic ketones and acetone equivalents obtained using dichloroamine-T. On the other
hand, when diamine (1,2-phenylene diamine or 1,2-naphthalene diamine) with heterocyclic ketone
(acetyl pyridine or acetyl pyrazines) in the presenece of conc. HCl and SiO2 was refluxed, quinoxaline
derivatives as yellow crystalline solids were isolated in high yields

Biosynthesis of undoped and copper doped tin oxide (SnO2) nanoparticles were carried out using
Canna indica leaf extracts as reducing agents. The as-synthesized nanoparticles were characterized
using the powder X-ray diffraction (PXRD), scanning electron microscope (SEM), Fourier transformed
infrared spectroscopy (FTIR), UV-visible spectroscopy and photoluminescence (PL). Antimicrobial
behaviour of the synthesized nanoparticles was examined. The XRD studies revealed that the rutile
structure for both undoped and copper doped SnO2 nanoparticles, with the absence of secondary
phases. The SEM micrographs clearly showed the formation of well-defined spherical particles with
no impure phases. The optical absorption studies explained that the variation of band gap with particle
size. The photoluminescent spectra showed an emission peaks at 390, 520 and 790 nm, which are
ascribed to the structural defects due to the oxygen vacancy. The antibacterial investigation suggested
a better antibacterial activity for Staphylococcus aureus against Escherialia coli bacterial strains

Published: June 2020

Graphene oxide (GO), reduced graphene oxide (rGO) and zinc oxide incorporated graphene oxide
(ZnO-GO) nanoparticles were synthesized by wet-chemical technique. The ZnO-GO nanocomposite
was synthesized from prepared graphene oxide. UV-visible and FTIR spectroscopy confirmed the
presence of oxygen functionalities on graphene oxide which was reduced to rGO on treatment with
the reducing agent. The XRD patterns revealed the formation of graphene oxide with a characteristic
peak at 10.6º which shifted to 24º during the formation of rGO. The crystallite size of all the synthesized
material was calculated using Scherrer′s formula. The morphological behaviour of all materials was
analyzed by scanning electron microscope (SEM). The electrochemical impedance data and Tafel
plots suggested that the composite material has low charge transfer resistance (Rct) and hence could
act as a conducting material. The photoelectric conversion values, η for GO, rGO and ZnO-GO were
calculated as 2.5, 5.7 and 7.5%, respectively and these values signify that the zinc oxide incorporated
graphene oxide material has unique properties of electron transport.

Published: June 2020

Regenerated silk fibroin beads (rSFB) were successfully prepared and applied to adsorbing methylene
blue and Lanasyn Navy M-DNL. The effects of contact time, initial pH and initial concentration of
dyes were analyzed. The experimental results showed that, the adsorption was pH dependent with a
high removal efficiency of methylene blue in basic range and high removal of Lanasyn Navy M-DNL
in acidic range. The adsorption process was analyzed by using Langmuir and Freundlich isotherm
models and the Langmuir isotherm model showed the best fitting to the isotherm data. The maximum
adsorption capacities for methylene blue and Lanasyn Navy M-DNL were 47.55 and 78.74 μmg/g,
respectively. The kinetics study showed that the adsorption process followed the second order kinetic
model. The SEM images demonstrated that after adsorption the dye was adsorbed onto the regenerated
silk fibroin beads surface. The adsorbent was stable and active for up to five successive cycles.
Regenerated silk fibroin beads showed to be an advantageous adsorbents in terms of availability,
which is beneficial for the wastewater treatment.

Utilization of Dissociation Constant (pKa) Value Perspective of -CH Acid in
Electrochemical Synthesis of 4H-Chromene and its Derivatives
Authors: Saraswat Apoorv , Pal Singh Rana Krishna
Published: June 2020

Activation of acidic-H in C-H chemistry through imposition of proper electrode potential is a matter
of concern among synthetic research community. In this study, our main aim is to get deeper insight
into the dissociation constant (pKa) value perspective of -CH acid and its utilization in electro-catalytic
transformation. Herein, a platinum cathode was being used to attract a covalently bonded electrons
that exist between C and active-H of CH-acid (dimedone) toward itself i.e. cathodic part to form
acidic-H and thus, form in-situ tautomeric enol form that acts as electro-generated base. Utilization of
this notability has been accomplished by electrochemical synthesis of 4H-chromene and its derivatives
by performing cathodic reduction. Due to acidic property of dimedone, cathodic platinum electrode
draw the potential switched to lower side that is being recorded through the potential-cum-galvanostat
which facilitates the faster transfer of electrons from -CH acid to form enolate ion of dimedone that
act as electro-generated base for the reaction media which simultaneously undergoes cascade reaction
(Michael addition/cyclization) on activated alkene (α-cyanocinnamonitrile derivatives). This approach
offers several advantages such as good yield, mild reaction condition, easy accessible, simple work-up
procedure and controlled potential selectivity at cathode. Use of no base is pivotal section of this
methodology. Electro-generated base is used instead of chemical toxic bases, so the present protocol
is green as electrons that acts as intrinsically sole reagent for the reaction media which is renewable,
hence sustainable for the safe future.

The interaction of an α-glucosidase inhibitors class of drug acarbose with globular proteins like bovine
serum albumin (BSA), human serum albumin (HSA) and haemoglobin studied by fluorescence, circular
dichroism (CD) spectroscopic methods. Acarbose is used for the treatment of diabetes mellitus type 2
and in some countries, prediabetes. The quenching constant (kq) values were calculated by using
fluorescence data, higher with haemoglobin (at λext = 405 nm). It indicates the quenching process for
the acarbose-haemoglobin interaction. Thus, the binding constants (kb), infers that the electrostatic,
hydrogen bonding, and intermolecular interactions play an important role in the proteins, and drug
interaction. The number of binding sites (n), between BSA, HSA and haemoglobin with acarbose was
estimated by fluorescence data, the highest binding sites (15.55) of acarbose-haemoglobin at (λext =
405nm) indicates that the strong interaction or high quenching interaction. The interactions between
BSA, HSA and haemoglobin with acarbose were confirmed by spectroscopic analysis and
thermodynamic determination. The circular dichroism (CD) spectra implied the significant change in
the conformation of BSA, HSA and haemoglobin upon binding with acarbose.
