Hacking systemic lupus erythematosus (SLE): outcomes of the Waterlupus hackathon
Authors: Cardwell Francesca S. , Bisung Elijah , Clarke Anne E. , Elliott Susan J.
Published: July 2020

Introduction

There is a growing literature demonstrating the benefits of engaging knowledge-users throughout the research process. We engaged a multi-stakeholder team to undertake a hackathon as part of an integrated knowledge translation (iKT) process to develop nonpharmacological interventions to enhance the economic lives of people with systemic lupus erythematosus (SLE). The aims of this research were to (1) increase understanding of the economic challenges of living with SLE through stakeholder engagement at a research hackathon; (2) investigate possible interventions to improve the economic lives of individuals affected by SLE in Canada; and (3) document the outcomes of the Waterlupus hackathon.

Methods

Waterlupus was held at the University of Waterloo in May 2019, attended by lupus advocacy organization representatives, researchers, physicians, individuals with lived experience and students. We conducted participant observation with participants’ understanding and consent; notes from the hackathon were qualitatively analyzed to document hackathon outcomes.

Results

At the conclusion of the 28­hour hackathon event, five teams pitched nonpharmacological interventions to address the economic challenges of living with SLE. The winning team’s pitch focussed on increasing accessibility of affordable sun-protective clothing. Other Waterlupus outcomes include increased awareness of SLE among participants, and professional and informal networking opportunities.

Conclusion

This paper contributes to a limited literature on health hackathons. The successful outcomes of Waterlupus emphasize the value of hackathons as an iKT tool. Research about how knowledge-users perceive hackathons is an important next step.
Estereotipos del amor. Superficies de placer. Rupturas en las portadas de discos de los 70 y 80
Authors: Medina Patricia
Published: July 2020

A partir de un repertorio de imágenes de portadas de discos de los setenta y los ochenta, se pretende indagar en diversas modalidades de estrategias comerciales utilizadas por la industria cultural. Modos de circulación y de proliferación masiva de imágenes constituyen un imaginario colectivo que instala determinados prejuicios y valoraciones que se convierten en la moral de las sociedades de consumo. Se analizarán imágenes estereotipadas evidenciando rasgos formales repetitivos que conllevan una fuerte carga ideológica y contribuyen a los intereses de venta. Asimismo, distinguiremos una amplia producción solapada que proponen desde sus supuestas desobediencias nuevas formas visuales. Preguntas asociadas a la construcción de género y a las relaciones sexo afectivas son algunas de las líneas interpretativas que surgirán de estas propuestas. La idea es hacerlas evidentes nuevamente.
El giro performativo en las artes visuales. A propósito de cuerpos, espacios y objetos puestos en acto
Authors: Valesini Silvina , Valent Guillermina
Published: July 2020

El proyecto se propone problematizar el campo de las artes visuales a la luz de su giro performativo, un enfoque que se caracteriza por la asimilación de recursos y estrategias vinculadas a las artes escénicas, en su actualización del concepto de teatralidad. De esta manera, la presencia de los cuerpos y de la acción como gesto significativo opera tensionando el concepto de representación. Así, la obra entendida como proceso extiende y complejiza sus alcances tanto en las condiciones de producción como en instancias de recepción. Se trata de una investigación exploratoria-interpretativa donde considerar la complejidad del fenómeno nos invita a proponer un abordaje transdisciplinario, que compromete el trabajo de cátedras de diferentes carreras de la Facultad de Artes de la Universidad Nacional de La Plata.
Two-Phase Exponential Model of Wealth Distribution
Authors: Radović Ognjen , Tomić Zoran , Stanković Jelena Z.
Published: July 2020

The topic of wealth and money distribution attracts great attention of economists, as well as researchers from other scientific fields, such as statistical physics and econophysics. An increasing number of models and simulations are being created in order to understand the process of wealth distribution and reaching the steady state of the distribution system. Also, the number of papers dealing with analysis and determining the distribution proportion is constantly growing, and, unlike the previous years, when the Pareto principle was “80-20”, today that principle could be “90-10”and even “90-20”. In this paper we present an agent-based simulation model derived from econophysics that describes the dynamics of wealth distribution. Two models of exponential function are tested: a one-phase model that uses the Newton’s law of cooling and a two-phase exponential function model. We found that exponential decreasing function adequately described the dynamics of wealth distribution, especially in the models without the possibility of borrowing money, and the validity of the Pareto principle “80-20” in these models could be confirmed.
Monetary Policy Transmission on Real Trends in Serbia – VAR Analysis
Authors: Obradović Jelena , Đorđević Marina
Published: July 2020

The efficiency of channels of monetary transmission varies from country to country and is conditioned by a number of factors that determine the economic and financial system of a country. In order to achieve the set monetary policy objectives, а central bank takes certain measures and employs instruments of monetary policy. Those instruments, however, act indirectly and with a certain lag. Due to these limitations in monetary policy effects, the analysis of the monetary transmission is of essence in every country as it enables its designers to determine an optimum monetary regime. In this paper, an analysis of monetary transmission in the Republic of Serbia is made using the Vector autoregressive model (VAR model). The research conducted is significant due to a current issue of the impact of monetary policy on actual economic trends, both in the developed and developing countries. On the basis of the research it is concluded that, in the time period under observation, the biggest impact on the fluctuations in industrial production in Serbia is that of monetary aggregate, whereas the biggest impact on the fluctuation in prices is that of key policy rate movements. The results of the analysis provide guidelines to monetary authorities to take necessary steps to shorten a lag period and eliminate restrictions in transmitting monetary impulses into real economic values.

Authors: Martsenkovskyi Dmytro , Napryeyenko Olexandr , Martsenkovsky Igor
Published: July 2020

Background

Depression is frequently comorbid with posttraumatic stress disorder (PTSD) and substantially influences its severity, course and outcomes. Published studies linking war-related paediatric PTSD and Major depressive disorder (MDD) were mainly based on cross-sectional studies.

Objective

To prospectively examine the role of PTSD and other risk/protective factors in the development of depression among adolescents with war-related trauma.

Methods

A longitudinal study of 160 adolescents aged 15–17 years with war-related trauma and displacement due to war in Eastern Ukraine was performed. Of the 160 adolescents, N = 86 met Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-4) criteria for PTSD. All adolescents underwent comprehensive psychiatric assessments that included Kiddie-Schedule for Affective Disorders and Schizophrenia-Present and Lifetime version (K-SADS-PL) administered to both parents and children. Traumatic exposure was assessed using the modified Traumatic Events Screening Inventory for children (TESI-C). PTSD and MDD were assessed with the Clinician-Administered PTSD Scale for Children and Adolescents (CAPS-CA) and Children's Depression Rating Scale-Revised (CDRS-R), and diagnosed using DSM-4 criteria. Follow-up and repeated measurements occurred at 6 and 12 months. During the study, adolescents requiring clinical care were referred for best available care in the community.

Results

Among 92.6% of study completers, 26/79 youth with PTSD developed MDD (32.9%), compared to 6/70 without PTSD (8.5%): relative risk (RR) = 3.83 (95% CI 1.67–8.78), p = 0.0014; Number needed to harm (NNTH) = 4.108 (8.53–2.7). Using logistic regression, variables of school attendance, ‘secondary’ traumatic exposure, and treatment with Trauma-focused Cognitive Behavioral Therapy (TF-CBT) were significantly correlated with the incidence of new-onset depression among adolescents with PTSD.

Conclusions

War-related trauma with subsequent PTSD appears to be a significant risk factor for the later development of depression in adolescents. The role of PTSD as a moderator of depression merits further investigation in larger scale longitudinal studies in diverse populations.
Metabolic syndrome and atherogenic indices in rheumatoid arthritis and their relationship with disease activity: A hospital-based study from northeast India
Authors: Bhattacharya Prasanta Kumar , Barman Bhupen , Jamil Md , Bora Kaustubh
Published: July 2020

Background and Objective

Metabolic syndrome (MetS), a constellation of metabolic abnormalities including hypertension, obesity, glucose intolerance, and dyslipidemia, is highly prevalent in patients with rheumatoid arthritis (RA). Our aim was to assess the magnitude of MetS and its determinants in RA patients and to evaluate different atherogenic indices that are reflective of the risk for future cardiovascular disease.

Patients and Methods

The study was conducted on 104 RA patients and 103 age- and sex-matched healthy controls. The frequency of MetS was assessed using the guidelines recommended for Asian Indians.

Results

A total of 104 RA patients participated with majority being females (85.6%), with a mean age of 43.82 ± 13.32 years. The frequency of MetS in patients with RA (36.5%) was significantly higher than in controls (15.5%). The atherogenic indices were found to be significantly higher in RA patients than controls (P < 0.01). On logistic regression, disease activity score (DAS28) scale for 28 joints and disease duration remained significant independent predictors of the presence of MetS in RA patients (P < 0.01 and 0.05, respectively).

Conclusions

RA is a kind of chronic disease of long course, and MetS and atherogenic indices are often concomitant in these patients. The study showed that the frequency of MetS was higher in patients with RA than in controls, and that DAS28 and disease duration remained significant independent predictors of the presence of MetS in RA patients.

Introduction

Enteropathogenic Escherichia coli (EPEC) is one of the main pathotypes causing gastroenteritis, particularly in young immunocompromised hosts. The study reports the prevalence, characterisation, and molecular epidemiology of EPEC from piglets in northeastern India.

Material and Methods

A total of 457 faecal samples were collected, from which 1,286 E. coli strains were isolated and screened by PCR. The resultant EPEC strains were serotyped and phenotypically characterised for resistance against 15 antimicrobials. Also, the phylogenetic sequence was analysed for 11 selected strains.

Results

A total of 42 strains (3.26%) belonged to atypical EPEC, of which, 15 (35.71%, and 2.29% of the 654 strains from this farm type) were isolated from organised and 27 (64.29%, and 4.27% of the 632 strains from this farm type) from unorganised farms; further, 5 (11.90% of the EPEC strains and 1.51% of the 330 strains from this breed) were isolated from the indigenous breeds and 37 (88.10%, and 3.87% of the 956 strains from this breed) from crossbred piglets. Serogroups O111 (11.9%) and O118 (7.14%) were the most prevalent of the 10 present. Sequence analysis of a length of the eaeA gene of 11 isolates of the region showed them to have 100% homology with each other and their identity ranged from 99.4% to 99.7% with GenBank reference sequences. All the EPEC isolates were multi-drug resistant, showing the highest resistance to amoxicillin (80.9%) and cephalexin (76.19%).

Conclusion

The study highlighted the association of EPEC with piglet’s diarrhoea in northeastern India. EPEC isolates belonged to many serotypes and phenotypically all were multi-drug resistant with close genetic homology.
Influence of wind power production on electricity market price
Authors: Valdmanis Gunars , Bazbauers Gatis
Published: July 2020

The study looks for a correlation between the share of wind power and electricity wholesale prices in the selected regions of the Nordic Baltic power market “Nord Pool Spot”. The aim is to see if and how strong an impact of wind power production has on power market prices. This information would help to perform long-term energy system analysis considering growing wind energy penetration. The actual hourly wind production and power consumption data as well as electricity prices from the year 2019 were used in the analysis. Results of the study revealed that in the analysed dataset there is no correlation between the share of wind power and the power prices, i.e. R-squared value is 0.003 for the Baltic region and 0.0064 for both trading areas of Denmark. In contrast, the R-squared value was almost 0.6 for a positive correlation between power demand and prices. The results mean that expected loss of interest to invest due to falling power prices, as a share of renewable power increases, should be examined more carefully and may not fulfil forecasts of policy makers and industry experts.
Turkish policy towards Libya after the February 2011 revolution
Authors: Dhanoon Rafea Shareef
Published: July 2020

The close relations between Turkey and Libya are still on the rise, and this was evident through Turkish support at all levels of the internationally recognized government of Al-Sarraj winner. The Memorandum of Understanding signed between Turkey and Libya on 27 / November 2019, in the areas of security and military cooperation and the determination of areas of influence revealed The navy, the extent of the historical close relationship between Ankara and Tripoli, just as the Turkish President Erdogan wanted to deliver a message to the West and other regional parties after the signing of the Memorandum of Understanding, that Turkey has a non-negotiable sovereign right to define the maritime spheres of influence and that this right stems from international law.

In light of these tracks, we will shed light on the orientations of Turkish policy towards Libya after the February 2011 revolution, by defining the determinants of those trends and examining the most important obstacles in the march of Turkish policy towards Libya.
Computational Prediction of Mutational Effects on the SARS-CoV-2 Binding by Relative Free Energy Calculations

Published: July 2020

The ability of coronaviruses to infect humans is invariably associated with their binding strengths to human receptor proteins. Both SARS-CoV-2, initially named 2019-nCoV, and SARS-CoV were reported to utilize angiotensin-converting enzyme 2 (ACE2) as an entry receptor in human cells. To better understand the interplay between SARS-CoV-2 and ACE2, we performed computational alanine scanning mutagenesis on the “hotspot” residues at protein-protein interfaces using relative free energy calculations. Our data suggest that the mutations in SARS-CoV-2 lead to a greater binding affinity relative to SARS-CoV. In addition, our free energy calculations provide insight into the infectious ability of viruses on a physical basis, and also provide useful information for the design of antiviral drugs.
Mechanistic Insights on Hypervalent Iodine-Mediated Styrene Hetero- and Homodimerization
Authors: Hussein Aqeel A. , Al-Yasari Ahmed , Ma Yumiao
Published: July 2020

A mechanistic insight into the hetero- and homodimerizations (HETD and HOMD) of styrenes promoted by hypervalent iodine reagents (HVIRs; DMP and PIDA) and facilitated by HFIP to yield all trans cyclobutanes is reported using density functional theory (DFT) calculations. The HFIP molecules lower the energy of the single electron oxidation (SEO) or initiation as a result of strong hydrogen bonding interactions that substantially stabilize the frontier orbitals before and after electron addition. The HETD or HOMD is a radically-characterized π-π stacked head-to-head stepwise [2+2] cycloaddition initiated via SEO by DMP or PIDA, respectively. DFT results supported by quasiclassical molecular dynamics simulations show that HOMD is a competing pathway to HETD although the latter is relatively faster, in accordance with experimental observations. The initiation is a rate-determining step as a thermodynamically endergonic and propagation is accomplished by radically-cationic hetero- and homodimerized intermediate as propagation is faster than single electron reduction (SER) or termination by radically-anionic HVIRs. Initiation by DMP found to be faster and less endergonic than by PIDA due to (1) the energy gap of electron transfer in a SEO step by I(V) is lower than I(III) and (2) the SOMO energy of the radical anion I(V) is lower than I(III). Furthermore, the presence of p-methoxy group is essential to underpin the SEO by which the more thermodynamically favorable SEO leads to a successful cycloaddition as the thermodynamic term represents a major contribution in the initiative barrier.
Exploring the Use of Gas Chromatography Coupled to Chemical Ionization Mass Spectrometry (GC-CI-MS) for Stable Isotope Labelling in Metabolomics

Published: July 2020

Isotopic labelling experiments have been utterly valuable to monitor the flux of metabolic reactions in biological systems, which is crucial to understand homeostatic alterations with disease. Experimental determination of metabolic fluxes can be inferred from a characteristic rearrangement of stable isotope tracers (e.g., 13C or 15N) that can be detected by mass spectrometry (MS). Metabolites measured are generally members of well-known metabolic pathways, and most of them can be detected using both gas chromatography (GC)-MS and liquid chromatography (LC)-MS. In here, we show that GC methods coupled to chemical ionization (CI) MS have a clear advantage over alternative methodologies due to GC’s superior chromatography separation efficiency and the fact that CI is a soft ionization technique that yields identifiable protonated molecular ion peaks. We tested diverse GC-CI-MS setups, including methane and isobutane reagent gases, triple quadrupole (QqQ) MS in SIM mode or selected ion clusters using optimized narrow-windows (~10 Da) in scan mode, and standard full scan methods using high resolution GC-(q)TOF and GC-Orbitrap systems. Isobutane as reagent gas in combination with both low-resolution (LR) and high-resolution (HR) MS showed the best performance, enabling precise detection of isotopologues in most metabolic intermediates of central carbon metabolism. Finally, with the aim of overcoming manual operations, we developed an R-based tool called isoSCAN that automatically quantifies all isotopologues of intermediate metabolites of glycolysis, TCA cycle, amino acids, pentose phosphate pathway and urea cycle from LRMS and HRMS data.

Understanding the status of gut microbiota has been recognized as crucial in health management and disease treatment. To meet the demands of medical and biological applications where rapid evaluation of gut microbiota in limited research environment is essential, we developed new sensing systems able to readout the overall characteristics of complex microbiota. Response patterns generated by a synthetic library of 12 charged block-copolymers with aggregation-induced emission units were analyzed with pattern recognition algorithms, allowing to identify the species/phyla of 16 axenic cultures of intestinal bacterial strains. More importantly, our method clearly classified artificial models of obesity-associated gut microbiota, and further succeeded in detecting sleep disorders in mice through comparative analysis of the normal/abnormal mouse gut microbiota. Our techniques can analyze complex bacterial samples far more quickly, simply and inexpensively than common metagenome-based methods, offering a powerful and complementary tool for gut microbiome analysis for practical use, e.g., in clinical settings.
