We describe the rare case of severe, acute myocarditis secondary to drug reaction with eosinophilia and systemic symptoms (DRESS) due to Vimovo. With an estimated morality rate of up to 10% DRESS is a potentially life–threatening condition that includes skin eruption, haematological abnormalities, lymphadenopathy and multiple internal organ involvement

Background: Partial anomalous pulmonary venous connection (PAPVC) occurs when at least one pulmonary vein drains into the right atrium or its tributaries rather than the left atrium, most commonly connecting with the superior vena cava (SVC). The Warden procedure involves transecting the SVC proximal to the uppermost connection of the pulmonary vein followed by proximal SVC reattachment to the right atrial appendage. However, descending thoracic aortic homograft replacement for SVC translocation has recently been introduced as a modified technique. Aims: This commentary aims to discuss the recent study by Said and colleagues who reported their experiences with 6 PAPVC cases undergoing a modified Warden procedure using thoracic aortic homograft SVC translocation. Methods: A comprehensive literature search was performed using multiple electronic databases in order to collate the relevant research evidence. Results: The Warden procedure is associated with a 10% incidence of SVC obstruction with many requiring reintervention. Meanwhile, using the aortic homograft for SVC translocation, Said et al. observed no SVC obstructions. In addition, this modified technique does not require anticoagulation and has demonstrated an improvement in long-term SVC patency. Nevertheless, it can be considered an expensive procedure. Moreover, since the thoracic aortic homograft utilised is biological tissue, only long-term follow-up will determine whether calcification and graft degeneration is an issue. Conclusion: It can be concluded that the modified Warden procedure is a safe and effective method to reconstruct the systemic venous drainage into the right atrium when a direct anastomosis under tension might be prone to re-stenosis.

The current study focuses on approximate analytical solution of three-dimensional MHD flow of an incompressible fluid through porous media over a stretching sheet using Exponentially decreasing series. The governing equations are transformed into a system of nonlinear ordinary differential equations with boundary conditions using the similarity transformation. It has been attempted to show the reliability and performance of the Dirichlet series in comparison with Direct Numerical Method (DNM). For various flow parameter values, the resulting quantities such as velocity profiles and skin friction coefficient are also geometrically presented.

In this article, a new approach for hiding personal information in speech is proposed. Speech modification is based on the long-term voice spectrum that reflects the individuality of the vocal tract. The depersonalized speech signal was objectively evaluated using fundamental frequency and intelligibility. The advantages of the proposed approach compared to the traditional technique based on normalization of vocal tract length are briefly discussed.

Particle size and surface trap effects on the third order nonlinear optical (NLO) properties of CsPbCl3 and CsPbBr3 perovskite quantum dots (PQD) have been investigated using femtosecond (fs) Z-scan experiment. Firstly, optical, morphological and structural characterizations of the synthesized PQDs were performed using linear absorption and photoluminescence (PL) spectra, XRD and TEM methods. Next, NLO properties of CsPbCl3 and CsPbBr3 PQDs with three different particle sizes and with and without surface trap states were studied at the operating wavelength of 800 nm and 3.564 x 1011 W/cm2 intensity. The calculated values of the nonlinear absorption coefficient, β, (~10-11 m/W), the nonlinear refraction coefficient,γ, (~ 10-17 m2/W), and third order susceptibilities, χ(3), (~ 10-11 esu) for both sample types were seen to be in line with the literature. The maximum γ values for CsPbCl3 and CsPbBr3 PQDs were observed in the large and medium particle sizes, respectively. In the case of surface trap free nanomaterials, the unitless figure of merits were found to be increased more than 100 folds for CsPbCl3 PQDs and 30 folds for CsPbBr3 PQDs. These results strongly indicate the significant potential of CsPbCl3 and CsPbBr3 PQDs for numerous nonlinear applications.

In this work we investigate singularities for the three types of developable surfaces, introduced by Izumiya and Takeuchi, in Lorentz 3 space and give a local classification in terms of k-order frame [3,4]. Moreover we search the necessary conditions of being a geodesic for principal direction curves of the rectifying developable surface.

In order to study the fluctuation law of suspended sediment concentration ( SSC) of different water layers in Xuliujing marginal shoal and deep groove of Yangtze River Estuary with time under spring, middle and neap tides, and analyze the relevant factors of SSC fluctuation in shoal and groove, so as to help calculate and calibrate line computation of SSC, infer continuous sediment transport rate and compilate sediment discharge in Xuliujing section, provide theoretical basis for scientific research on analysis of Yangtze Estuary channel erosion and deposition and river regime change, river regulation and wading projects plan. Used horizontal sampler, bottom sampler and other instruments to conduct on-site hydrological and sediment tests of 1#(marginal shoal) and 4#(deep groove) measuring verticals on Yangtze Estuary Xuliujing Section.

Chimeric antigen receptor (CAR) expressing T cells are a complex and heterogeneous gene therapy product with variable phenotype composition. A higher proportion of less differentiated CAR T cells is usually associated with improved antitumoral function and persistence. We describe here a novel receptor-targeted lentiviral vector (LV), named 62L-LV, that preferentially transduces less differentiated T cells marked by the L-selectin receptor CD62L, with transduction rates of up to 70% of CD4 + and 50% of CD8 + primary T cells. Remarkably, higher amounts of less differentiated T cells are transduced and preserved upon long-term cultivation using 62L-LV compared to VSV-LV. Interestingly, shed CD62L neither altered binding of 62L-LV particles to T cells nor impacted their transduction. Incubation of two days activated T lymphocytes with 62L-LV or VSV-LV for only 24 hours was sufficient to generate CAR T cells that controlled tumor growth in an NSG mouse model. The data prove that potent CAR T cells can be generated by short-term ex vivo exposure of primary cells to LVs. As a first vector type that preferentially transduces less differentiated T lymphocytes, 62L-LV has the potential to circumvent cumbersome selection of T cell subtypes and offers substantial shortening of the CAR T cell manufacturing process.

Rheumatoid arthritis(RA) is a systemic autoimmune disease characterized by inflammation of the synovial membrane of joints. However, RA can be associated with extra-articular manifestations including vasculitis that occurs exceptionally in the retina. We report two retinal vasculitis (RV) cases was a direct consequence of rheumatoid disease in active RA patients.

In recent years, spectrum analysis and computation have developed rapidly in order to explore and characterize the properties of network sciences. Let Ln be obtained from the transformation of the graph L6,4,4 n , which obtained by attaching crossed two four-membered rings to the terminal of crossed phenylenes. Firstly, we study the (nomalized) Laplacian spectrum of Ln based on the decomposition theorem for the corresponding matrices. Secondly, we obtain the closed-term fomulas for the (multiplicative degree) Kirchhoff index and the number of spanning trees from the relationship between roots and coefficients in linear chain networks. Finally, we are surprised to find that the (multiplicative degree) Kirchhoff index of Ln is nearly to one quarter of its (Gutman) Wiener index when n tends to infinity.

The 2q chromosome region encodes the cluster of sodium channel genes important in severe childhood epilepsy phenotypes. Our case examines the extent that 2q24.3-24.3 gene deletions contribute to our patient's complex medically refractory epilepsy and supports the use of fenfluramine and ketogenic diet as an effective treatment for these patients.

The automatic speaker verification spoofing (ASVspoof) challenge series is crucial for enhancing the spoofing consideration and the countermeasures growth. Although the recent ASVspoof 2019 validation results indicate the significant capability to identify most attacks, the model’s recognition effect is still poor for some attacks. This paper presents the Online Hard Example Mining (OHEM) algorithm for detecting unknown voice spoofing attacks. The OHEM is utilized to overcome the imbalance between simple and hard samples in the dataset. The presented system provides an equal error rate (EER) of 0.77% on the ASVspoof 2019 Challenge logical access scenario’s evaluation set.

Let M be an indefinite inner product module over a *-ring of characteristic 2. We show that every self-adjoint operator on M admits Halmos, Egervary and Sz.-Nagy dilations.

AIMS Doxorubicin-induced cardiotoxicity (DIC) is a significant cause of mortality in cancer care. This study was conducted to establish the frequency of DIC in Zimbabwean breast cancer patients on doxorubicin and to test the DIC predictive power of genetic biomarkers. METHODS A cohort of 50 Zimbabwean breast cancer patients treated with doxorubicin were followed up for 12 months with serial echocardiography and genotyped for UGTA1A6*4, SLC28A3 and RARG. 11% of the patients experienced DIC. RESULTS The frequency of SLC28A3 (rs7853758), UGT1A6*4 (rs17863783) and RARG (rs2229774) was 60.7%, 17.9% and 14.3% respectively. No association between DIC and the three variants was observed. CONCLUSIONS This is the first study on the prevalence of DIC and associated genetic biomarker predictive evaluation in Zimbabwean breast cancer patients. The genetic frequencies observed in our study was different to that reported in other populations. A larger sample size with a longer follow up time will be necessary in future studies.

Anthropic disturbances are driving unprecedented changes in forest ecosystem functions and biogeochemical processes, hindering the forests’ benefits to society. Litter decomposition is one of the most critical processes that regulates the carbon and nutrient cycling. However, it is unclear how degradation affects litter decomposition and carbon and nutrient dynamics. The main objective of this study was to evaluate the effect of forest degradation on the production and decomposition of litter and C:N:P stoichiometry dynamics in a temperate forest in south-central Chile. Litter traps and litter bags were installed in three Long Term Research Forest Plots (LTER) representing different conservation states: mature, secondary, and degraded Nothofagus forests. The litter production, decomposition, and C, N, and P concentrations were evaluated monthly for one year. The total litter input varied between 3.5 to 1.1 Mg ha⁻¹ year⁻¹ in the mature and degraded forests, respectively. We found the highest lignin and nutrient levels in the degraded forest and the lowest in the mature forest. The remanent litter mass reached 56% in the mature forest, while it was only 93% in the degraded forest. Decomposing litter showed the lowest C:N and C:P ratios in the mature forest during most of the year. The balance between inputs and outputs yielded a greater accumulation of litter in the mature forests. Our results strongly suggest that anthropic degradation has altered litter quality, production, decomposition, and nutrient dynamics. Further research should be focused on assessing how changes in litter dynamics affect natural forest regeneration and soil biogeochemical functioning.

Toxin production in planktonic protists is widespread and comprises an effective mechanism to eliminate competitors or grazers. Toxins released into the water can mediate the immobilization of prey for subsequent consumption or can mediate the lysis and uptake of the released nutrients. For the worldwide-distributed ichthyotoxic and mixotrophic haptophyte Prymnesium parvum, the relationship between toxin production; impact on co-occurring species, and mixotrophy remains blurred. In the current study, we show that changes in salinities (5 vs 30), phosphorous (P) availabilities (P-replete vs P-deplete) and cell densities affect growth, toxicity and mixotrophy in P. parvum. Cell density positively affected cellular toxin content by a factor of up to 10. Low salinity resulted in a higher mortality of the cryptophyte prey Teleaulax acuta, with ~80% of cells being lysed after 2 h of incubation. However, phagotrophic rates were higher in P-deplete conditions, independent of the salinity. Transcriptomic analysis of the monocultures revealed the up-regulation of genes involved in endocytosis under either low salinity and phosphorous, suggesting that this process is evolutionarily conserved, triggered by environmental stressors and independent of prey presence. Polyketide synthase genes, potentially involved in toxin biosynthesis, exhibited distinct expression patterns, depending on the physiological status, toxicity and with generally higher expression under the high cell density conditions. Overall, our study contributes to a better understanding of the dynamics between the two critical processes of toxin production and mixotrophy, and has important implications for bloom formation and its maintenance in this ecologically important species.

There is a growing need for nematode-resistant Pinaceae species seedlings to cope with the degradation of global coniferous forests due to the prevalence of pine wilt disease. One of obstacle of Pinaceae species plantlets commercialization is the regeneration plantlets from a controlled, sterile environment to the field while maintaining a high survival rate. The low survival rate of plantlets transferred from a lab to soil is mainly because of the quality of plantlet which makes commercialization challenging. For this paper, we investigated the factors that influence the growth of post-germination somatic regeneration plants (SRPs) to promote the application of nematode-resistant of Pinus thunbergii. The results indicated that, for rooted plantlet, a suitable liquid medium (1/2 WPM), transplantation stroma (perlite and vermiculite =1:1), and carbohydrate (20 g/L sucrose) were effective for promoting the growth of SRPs. While, for unrooted plantlets, 1 ug/L of brassinolide enhanced plantlets growth and rooting. In the laboratory domestication stage, under light spectrum treatments, blue light (B) significantly promoted the longitudinal growth of shoots, while red light (R) was of benefit for the improvement of root growth. The optimal combination of R/B was the 8:2. After this domestication culture, SRPs of Pinus thunbergii could be directly transplanted to the field with a higher survival rate (85.2%). This is the first report on domestication of conifer regeneration plants, that will increase the possibility of afforestation of Pinaceae or other woody plants. In addition, it contributes to breeding project of pine resistance to pine wilt disease.

The existing prefabricated wireline construction technology is difficult to accurately measure the real-time length of the deployed wires, resulting in too large construction errors and cannot be popularized and applied. To this end, a length measuring device that can accurately measure the length of the wire during the construction of the prefabricated wire is developed. In terms of the hardware of the length measuring equipment, based on the construction characteristics of the prefabricated wiring and the characteristics of the wire, the photoelectric encoder and the STC8G series single chip microcomputer are used to complete the collection and processing of the wire length data, and the mature and stable LoRa technology is used to complete the wireless transmission of the data. In terms of software program of length measurement equipment, the measurement of wire length data, transmission and interaction of control command signals are realized by optimizing length measurement scheme, interface development of terminal equipment and information interaction program design. Finally, according to the actual working conditions of the prefabricated wiring construction, the mechanical structure of the length measuring equipment is designed, and the assembly is completed. The developed length measuring equipment has been successfully applied to practical projects. According to the wire length measuring equipment, the deviation between the observation sag and the design sag after the wire length is measured by the wire length measuring equipment is 2.0%, which meets the design requirement of ±2.5%.

Objective Tracheostomy is performed for various indications ranging from prolonged ventilation to airway obstruction. Many factors may play a role in the incidence of complications in the immediate post-operative period including patient-related factors. The relationship between obstructive pulmonary diseases and acute post-tracheostomy complications has been incompletely studied. Chronic obstructive pulmonary disease (COPD), obstructive sleep apnea (OSA), and asthma are some of the most common pulmonary pathologies in the United States and given the clinical utility of tracheostomies among these patients, it is important to characterize the risk of acute post-operative complications. Design A retrospective chart review identified tracheostomy patients from January 2017 through December 2018 at an academic cancer center. Medical records were reviewed for the technique used, complications, and contributing patient factors. Post-operative complications were defined as any tracheostomy-related adverse event occurring within 14 days. Patient factors examined included demographics, comorbidities, and body mass index (BMI). Results The most common indication for tracheostomy among the 321 patients that met inclusion criteria was airway obstruction or a head and neck cancer surgical procedure. Obstructive pulmonary pathology (COPD, OSA, asthma) was moderately associated with acute complications in bivariate analysis (13.4% complications, p = 0.039). Among the secondary outcomes measured, radiation was associated with early complications occurring in post-operative days 0-6 (1.1%, p = 0.029). Conclusion Obstructive pulmonary patients may have a higher risk of acute post-tracheostomy complications which is clinically significant when considering the utility of ventilation and tracheostomy in the management of acute respiratory failure secondary to these conditions.

When Λ is the cosmological constant concerning (g µν) 2 [3, 10], we use the constructed new action to get the new cosmological constant and deduce a new form of f(R) using the coupled effects of gravity and quantum fields.

Pyrazole derivatives have noteworthy attention in optoelectronic field since they demonstrate distinctive properties in semiconducting devices such as organic light emitting diodes (OLEDs), nonlinear optical (NLO) and solar cells. organic field effect transistors (OFETs). Therefore, to establish the relationship between the structure and property of the molecules, we explored influence of nitro groups on the 3D molecular structures, reorganization energy, absorption spectra, frontier orbitals, ionization potential (IP), electronic affinity (EA), intra-molecular charge transfer (ICT) and charge transport behaviour of the two π-conjugated pyrazole compunds through single crystal x-ray crystallographic and quantum chemical calculations by considering Marcus Electron Transfer Theory and Density Functional Theory. Our experimental and theoretical results predicted that incorporation of the nitro groups to the molecule skeleton increased the rigidity of the conjugated system and improve the efficient charge injection in electronic devices by lowering the hole (λ_h) and electron (λ_e) reorganization energy from 0.48eV to 0.34 eV, 0.44 eV to 0.26 eV, respectively which can be effective way to design molecules with desired electronic properties via smart chemical structural modification. In addition, both molecules aggregate with the close preferred π⋯π stacking interactions (J and antiparallel H type) and multiple intermolecular interactions in their solid phases. Accordingly, both molecules are suggested to be quite suitable for p-type semiconducting materials with small reorganization energy and preferred stacking modes in solid phase. In addition, this study paves the way for the design and synthesis of new conjugated pyrazole molecules for high device performance.

Background and Purpose: The aromatase enzyme plays a fundamental role in addressing the development of estrogen receptors and giving attention to the therapy of reproductive disorders and cancer diseases. In clinical use, the objectionable effects found in these target inhibitors are indispensable in finding novel aromatase inhibitors with more selective, less toxic, and more effective drug potency. Experimental Approach: The research framework of this study is to identify a potent inhibitor for the aromatase target by profiling molecular descriptors of the ligand and finding a functional pocket of the target by docking and MD simulations. For assessing cellular metabolic activities as an indicator of cell viability and cytotoxicity, in-vitro studies were performed by using colorimetric MTT assay. Cell morphology was assessed by phase-contrast light microscope. Cell cycle distribution and apoptosis were determined by flowcytometry and Annexin V-FITC/PI staining assay. Key Results: This study reported herein the most promising compound CHEMBL598797 (Ziprasidone) showed excellent activity potential to inhibit aromatase in search of finding the novel compound based on better drug design methods and experimental studies and could be effective as the high potential drug candidate against aromatase enzyme. Conclusion and Implications: We concluded that the compound ziprasidone effectively blocks the cell cycle at the G1-S phase and induces cancer cell death. Further in-vivo studies can be evaluated for developing this compound as an anticancer agent. Overall, our outcomes based on the in-silico and the high-quality experimental results may pave the way for identifying effective drug candidates for better therapeutic interest for breast cancer.
