Fulminant eosinophilic myocarditis treated with steroids and mechanical unloading: a case report

Abstract Background Eosinophilic myocarditis is a rare form of myocardial inflammatory disease. Eosinophilic infiltration of the myocardium is often the consequence of a systemic disorder but can remain unexplained in up to a third of patients. The disease course can range from mild to fulminant myocarditis and mortality remains high for fulminant cases. Case summary A 42-year-old male was admitted for cardiogenic shock. He presented in another hospital with fever, low blood pressure, diffuse electrocardiogram-abnormalities, and elevated troponin T (4.5 µg/L; reference <0.013 µg/L) levels. Coronary angiography was unremarkable. Mechanical circulatory support with the ImpellaTM CP device was initiated. Since fulminant myocarditis was suspected and magnetic resonance imaging was not feasible in urgency, an endomyocardial biopsy was performed. He transiently developed right ventricular failure after ImpellaTM implantation, requiring the re-institution of an inotropic agent. Biopsy showed eosinophilic myocarditis, even though there was no increase in the peripheral blood eosinophil count. Methylprednisone and Ramipril were initiated to which he responded well. No systemic disease or parasitic infection was found during further work-up. Left ventricular ejection fraction rapidly improved and was completely normalized at discharge. Discussion This case demonstrates the usefulness of myocardial biopsy in fulminant myocarditis since the only histopathology guided us towards the diagnosis of eosinophilic myocarditis. Treatment with methylprednisone and an angiotensin-converting enzyme-inhibitor resulted in rapid improvement. Awake mechanical circulatory support with the ImpellaTM device proved feasible and might have helped by unloading the left ventricle, as was reflected in an immediate decrease in troponin levels, even before methylprednisone initiation.
Does Level of Education Influence the Development of Adolescents’ Mindsets?

In the present study, we compared the mindset of preuniversity students and (primary and secondary) vocational students. Participants comprised of 173 students attending preuniversity education and 101 students attending vocational education. All participants completed a mindset questionnaire. We expected, based on previous educational experiences, that preuniversity students would show on average a higher score (i.e., more of a growth mindset) than vocational students. Results indicated, however, that there was hardly any difference in mindset between vocational and preuniversity students. The mindset of adolescents is therefore not influenced by the level of education.
Iron Speciation and Physiological Analysis Indicate that Synechococcus sp. PCC 7002 Reduces Amorphous and Crystalline Iron Forms in Synthetic Seawater Medium

Cyanobacteria have high iron requirements due to iron-rich photosynthetic machineries. Despite the high concentrations of iron in the Earth’s crust, iron is limiting in many marine environments due to iron’s low solubility. Oxic conditions leave a large portion of the ocean’s iron pool unavailable for biotic uptake, and so the physiochemical properties of iron are hugely important for iron’s bioavailability. Our study is the first to investigate the effect of iron source on iron internalization and extracellular reduction by Synechococcus sp. PCC 7002. The results indicated that the amorphous iron hydrolysis species produced by FeCl3 better support growth in Synechococcus through more efficient iron internalization and a larger degree of extracellular reduction of iron than the crystalline FeO(OH). An analysis of dissolved iron (II) indicated that biogenic reduction took place in cultures of Synechococcus grown on both FeCl3 and FeO(OH).
An off-line output feedback RMPC-LPV applied to an inverted pendulum using relaxed LMI procedures

This paper aims an off-line output-feedback robust model predictive control (RMPC) using linear matrix inequalities (LMIs) applied to the angle position control of an inverted pendulum modeled by Linear Parameters Varying (LPV) affine scheme. The presented methodology involves the an off-line RMPC-LPV state feedback, which the gains are LPV by LMIs and stored in the look-up table. Also, it is presented a robust observer design using LMIs that is ensured the feasibility of the output feedback stability. The control strategies presented in this study considers the online and off-line state space feedback and off-line feedback control design along with state observer. The comparative analysis of the numerical results and cost indices evidence the suitability of the proposed methodology and the advantages of output feedback RMPC-LPV in comparison with the typical approaches based in the same control design conditions.
Discovering Social Desires and Conflicts from Subculture Narrative Multimedia

This study aims at discovering social desires and conflicts from subculture narrative multimedia. Since one of the primary purposes in the subculture consumption is vicarious satisfaction, the subculture works straightforwardly describe what their readers want to achieve and break down. The latent desires and conflicts are useful for understanding our society and realizing smart governance. To discover the social issues, we concentrate on that each subculture genre has a unique imaginary world that consists of inventive subjects. We suppose that the subjects correspond to individual social issues. For example, game fiction, one of the popular genres, describes a world like video games. Under game systems, everyone gets the same results for the same efforts, and it can be interpreted as critics for the social inequality issue. Therefore, we first extract subjects of genres and measure the membership degrees of subculture works for each genre. Using the subjects and membership degrees, we build a genealogy tree of subculture genres by tracing their evolution and differentiation. Then, we extract social issues by searching for the subjects that come from the real world, not imaginary. If a subculture work criticizes authoritarianism, it might include subjects such as government officials and bureaucrats. A combination of the social issues and genre genealogy tree will show diachronic changes in our society. We have evaluated the proposed methods by extracting social issues reflected in Korean web novels.
Status of Aqua Drugs Applied in Freshwater Aquaculture of Moulvibazar District, Bangladesh

Aims: Our study aimed to assess the current situation of accessibility and the use of various chemicals and medicines in freshwater aquaculture. Methodology: A questionnaire interview survey was conducted among 14 aquaculture farms and 23 aqua chemical retailers. Results: Due to easy availability, farmers used large quantities of lime and cow dung to prepare ponds and manage water quality. Beside these rotenone, zeolite gold, acme’s zeolite, aqua kleen, urea and TSP (triple super phosphate) are also found. Timsen, polgard-plus, deltix, virex, magic-fos and pond-safe were mostly used as a disinfectant. Epizootic Ulcerative Syndrome (EUS) disease was found predominantly in the farmer's pond. For disease treatment, renamycine soluble powder (oxy tetracycline) was used, 32% farmers. Two oxygen suppliers oxy gold and oxy life were used to increase oxygen concentration. Among 11 types of growth promoters were found in chemical shops in which charger gel and rapid grow were mostly used. Most farmers use gas trap and gasonex plus as gas reducer. Conclusions: There are mostly six categories of 48 aqua drugs and chemicals are observed and treated for health monitoring of fish and shellfish. Due to lack of knowledge concerning the proper dosage and procedure of using chemicals, technique of application and indiscriminate practice of chemicals etc. are common problems of aqua drugs in Moulvibazar district.
The Primate Origins of Human Social Cognition

ABSTRACT The ability to understand the mental states of other individuals is central to human social behavior, yet some theory of mind capacities are shared with other species. Comparisons of theory of mind skills across humans and other primates can provide a critical test of the cognitive prerequisites necessary for different theory of mind skills to emerge. A fundamental difference between humans and non-humans is language: while language may scaffold some developing theory of mind skills in humans, other species do not have similar capacities for or immersion in language. Comparative work can therefore provide a new line of evidence to test the role of language in the emergence of complex social cognition. Here we first provide an overview of the evidence for shared aspects of theory of mind in other primates, and then examine the evidence for apparently human-unique aspects of theory of mind that may be linked to language. We finally contrast different evolutionary processes, such as competition and cooperation, that may have been important for primate social cognition versus human-specific forms of theory of mind. We argue that this evolutionary perspective can help adjudicate between different proposals on the link between human-specific forms of social cognition and language.
Sorption Mechanism of Europium by Apatite Using Rutherford Backscattering Spectroscopy and Resonant Nuclear Reaction Analysis

A sorption mechanism of Eu, an analog of trivalent TRU, on apatite has been studied based on the depth profiles obtained by Rutherford backscattering spectroscopy (RBS) and resonant nuclear reaction analysis (RNRA). A positive peak for Eu and a negative peak for Ca were observed in an RBS spectrum obtained by subtracting fresh apatite one from a Eu-sorbed apatite one. This indicates that at least part of Eu was sorbed on the apatite, while a fraction of Ca was released from the apatite. The peak height for Eu in the RBS spectrum of apatite increased with increase in temperature of the sorption experiments. The depth profiles of hydrogen of the Eu-sorbed apatites were similar to that of fresh apatite. This indicates that amount of Ca exchanged for hydrogen is very low. In the sorption experiments the concentrations of Eu in the solutions decreased with increase in the temperature. On the contrary, the concentrations of Ca increased with increase in the temperature. Thus, it is concluded that a fraction of .
Experimental and theoretical study of finite-aperture tapered unstable resonator lasers

We present experimental and theoretical results of a novel finite-aperture tapered unstable resonator laser under pulsed and CW operations. At a current of 16 A an output power of about 10 W is reached. The beam parameter increases from M2 ≈ 10 at P = 1 W to M2 ≈ 20 at P = 10 W. Spatial–temporal simulations were performed to elucidate this experimental finding.
Interleukin-17 Receptor A1 Gene Knockout Causes Weight Loss and Reduction of Intestinal Metabolism-Related Genes in The Japanese Medaka, Oryzias Latipes

In the intestine, the host must be able to control the gut microbiota and efficiently absorb transiently supplied metabolites, at the risk of enormous infection. In mammals, the inflammatory cytokine interleukin (IL)-17A/F is one of the key mediators in the intestinal immune system. However, many functions of IL-17 in vertebrate intestines remain unclarified. In this study, we established a gene-knockout (KO) model of IL-17 receptor A1 (RA1), an IL-17A/F receptor, in Japanese medaka (Oryzias latipes) using genome editing technique and the phenotypes were compared to wild type (WT) based on transcriptome analyses. Upon hatching, homozygous IL-17RA1-KO medaka mutants showed no significant morphological abnormality. However, after 4 months, significant weight decreases and reduced survival rates were observed in IL-17RA1-KO medaka. Comparing gene-expression patterns in WT and IL-17RA1-KO medaka revealed that various metabolism- and immune-related genes were significantly down-regulated in IL-17RA1-KO medaka intestine, particularly genes related to mevalonate metabolism (mvda, acat2, hmgcs1, and hmgcra) and genes related to IL-17 signaling (such as il17c, il17a/f1, and rorc) were found to be decreased. These findings show that IL-17RA regulated immune- and various metabolism-related genes in the intestine for maintaining the health of Japanese medaka.
Women Participation in Sub-National Level Politics in Ghana's Fourth Republic

Debate over the factors that perpetuate male dominance in political representation all over the world continues. Several factors have been cited, including the fact that women have a weak foundation in political party leadership which forms the basis for subsequent progression in leadership. In spite of the fact that women have the capacity to compete favorably in national politics if they have a say in choosing who stands for elections at political party level, several studies tend to pay less attention on women’s leadership in political parties at the subnational level. Using qualitative methods, the paper makes a contribution to women’s participation in political leadership using the two dominant political parties, the National Democratic Congress and New Patriotic Party, that have alternated political power in Ghana since the return to constitutional rule in 1993. Findings showed that women’s representation in political party leadership at the subnational level mirrors national trends, albeit some local particularities including unfavorable meeting time where such decisions are taken. The paper concludes that the creation of the women’s wings in Ghanaian political parties and the institutionalization of financial waivers for women are necessary but not sufficient conditions to boost women activism in subnational party politics.

ABSTRACT Tannase is an enzyme that causes hydrolysis of a group of tannins (gallo-tannins) to gallic acid and glucose. This enzyme is of importance due to its numerous applications in many fields, such as in the food industry by enhancing tea and coffee flavor and improving the quality of fruit juices rich in tannins. Tannase is also of importance in improving the quality of animal feed. Gallic acid is applied in the drug industry, and the production of antioxidants is used in the oil industry. This study was carried out to improve production of tannase from genus Bacillus using spent tea as a substrate by submerged fermentation and applying the statistical design Response Surface Methodology (RSM). Five parameters were considered, and each parameter was studied at five levels. They were temperature range (25 to 45 ̊C), pH (3–8), incubation period (24–120 hours), spent tea (0.5–2.5%) and rotation speed (100–300rpm). Results obtained revealed that optimum conditions for maximum production of tannase were: temperature at 35 ̊C, pH at 5, incubation time of 48 hours, spent tea concentration 1.5%, and rotation speed of 150 rpm. We recommend that further studies be carried out to clarify and determine the properties of crude and purified enzymes.
Monte Carlo Simulation of Droplet Nucleation in RAFT Free Radical Miniemulsion Polymerization

Abstract The early stages of the reversible addition/fragmentation transfer (RAFT) miniemulsion polymerization were simulated, focusing on the effect of the RAFT agent on droplet nucleation. For highly reactive RAFT agents, a large number of free radicals (Nc) needed to be captured by a droplet in order to initiate polymerization in the droplet, which was totally different from the behavior of regular miniemulsion polymerization. More interestingly, it was found that droplet size had a significant influence on Nc value. It was shown that the RAFT agent has a significant influence on miniemulsion polymerization, leading to long induction periods and retardation of polymerization. In addition, miniemulsion droplets with different sizes are nucleated at different times, which could lead to very low nucleation efficiency. The results would be very helpful in understanding and designing a RAFT miniemulsion polymerization system.
Determinação espectrofotométrica de alumínio em concentrados salinos utilizados em hemodiálise empregando pré-concentração em fluxo

An automatic flow injection procedure for spectrophotometric aluminium determination in purified water and solutions containing high salts concentrations used for hemodyalisis treatment was developed. The method was base on reaction of Al3+ with cianine eriochrome R (ECR) after preconcentration using the AG50W-X8 cationic-exchange resin. Elution was carried out using a 1 % (m/v) calcium chloride solution. The manifold comprised an automatic proporcional injector controlled by a computer equipped with an eletronic interface and software written in QuicBASIC 4.5 with facilities to control the injector and perform data acquisition. Samples with concentration ranging from 4.96 to 19.90 µg L-1 Al were analyzed and recoveries between 88 and 113% were obtained by using the standard addition method. Other profitable analytical characteristics such as a relative standard deviation 1.3 % (n = 10) for a typical sample 14.5 µg L-1 Al, a linear response ranging up to 60.0 µg L-1Al, and a sampling throughput of 10 determinations per hour were achieved. A detection limit of 4.2 µg L-1 Al was estimated as suggested by IUPAC.
Critical Social Inclusion as an alternative to integration discourses in Finnish and Canadian Integration Education Programs

This article represents a synopsis of research findings obtained during multiple case study fieldwork in Finland and Canada (2015-2017) examining implementations of critical social inclusion in integration educations, specifically Swedish for Immigrants (SFI) and Language Instruction for Newcomers to Canada (LINC). Anti-oppressive methodologies (AOP), as well as perspectives integrated from Critical Whiteness Studies (CWS) and Critical Migration Studies (CMS) with their ideals of challenging structural racism and working for social change inform critical social inclusion as well as the study’s research design. The empirical findings show that social inclusion within SFI and LINC programs was tangled, episodic, and far from straightforward. Its implementation depended upon a number of enabling and disabling factors such as the role ascribed to language acquisition and critical citizenship perspectives in curricula, interrogations of civic integrationism and institutional whiteness within programs, as well as the prevailing political climates outside of the classroom. A pivotal conclusion is that if critical perspectives of social inclusion are to become a lived reality for all program participants, then majorities must also be subjected to integration regimes.
Formation of new crystal faces on TiO2 particles by treatment with aqueous HF solution or hot sulfuric acid

We have demonstrated that new crystal faces are generated on anatase and rutile TiO2 particles by means of chemical etching in aqueous hydrofluoric acid or hot sulfuric acid. In the treatment with aqueous hydrofluoric acid, the {112} face of anatase particles and the {021} face of rutile particles are newly formed. When treated with hot sulfuric acid, anatase particles exposed the {122} face and rutile particles exposed the {001}, {010}, {021} and {121} faces. In both cases, anatase particles are etched at a higher rate than rutile particles. The etched particles are expected to show photocatalytic properties unique to the crystal faces. For example, the {112} face of anatase particles is demonstrated to be active in the oxidation of Pb2+ ions.
Empirical studies on the impact of filter-based ranking feature selection on security vulnerability prediction

National Natural Science Foundation of China, Grant/Award Numbers: 61702041, 61202006; Guangxi Key Laboratory of Trusted Software, Grant/Award Number: kx202012; Jiangsu Government Scholarship for Overseas Studies Abstract Security vulnerability prediction (SVP) can construct models to identify potentially vulnerable program modules via machine learning. Two kinds of features from different points of view are used to measure the extracted modules in previous studies. One kind considers traditional software metrics as features, and the other kind uses text mining to extract term vectors as features. Therefore, gathered SVP data sets often have numerous features and result in the curse of dimensionality. In this article, we mainly investigate the impact of filter‐based ranking feature selection (FRFS) methods on SVP, since other types of feature selection methods have too much computational cost. In empirical studies, we first consider three real‐world large‐scale web applications. Then we consider seven methods from three FRFS categories for FRFS and use a random forest classifier to construct SVP models. Final results show that given the similar code inspection cost, using FRFS can improve the performance of SVPwhen comparedwith state‐of‐the‐art baselines. Moreover, we use McNemar's test to perform diversity analysis on identified vulnerable modules by using different FRFS methods, and we are surprised to find that almost all the FRFS methods can identify similar vulnerable modules via diversity analysis.
Ink identification by time‐of‐flight secondary ion mass spectroscopy

This work is devoted to the secondary ion mass spectroscopic application in the studies of ink layering on paper. Optical methods are often unreliable in the identification of ink layering on substrates. We demonstrated the power of time‐of‐flight secondary ion mass spectroscopy (ToF‐SIMS) by measuring the secondary ion mass spectra of handwriting on paper and assessing the characteristic ions for each colored ink. These ions were then used to collect images from overlapping handwritings. It was shown that the method could reliably determine which color was applied to the paper first. This work has potential applications in forensic studies. Copyright © 2006 John Wiley & Sons, Ltd.
