Objective(s): The goal of this study was to elucidate harmful complications of intraoperative hyperglycemia following children cardiac surgery and benefits of insulin administration for accurate blood sugar controlling. Design: Randomized clinical trial Setting: operating room of shahid madani hospital Patients: 50 patients who were children under 12 years old undergoing cardiac surgery using Cardiopulmonary Bypass (CPB). Interventions: Intraoperative insulin infusion was administered intravenously targeting at blood sugar levels of 110-140mg/dL Measurements and Main Results: Blood sugar and ABG were measured every 30 min during operation. The means of hospitalization and extubation time were more in the placebo than study group (P=0.03) and (P=0.005), respectively. However, the mean of hospitalization in the ICU ward was not significantly between groups. Conclusions: Hyperglycemia prevalence was lower in our study than mentioned studies in which the patients were either given insulin or not. Hyperglycemia duration has relation with long hospitalization time in ICU and hospital. These findings suggest the positive effect of accurate blood sugar control on reducing complication and hospitalization time in children undergoing cardiac surgery.

Pulmonary atresia with ventricular septal defect (PA-VSD) is a congenital complex cardiac anomaly. The blood supply to the lungs can be from patent ductus arteriosus (PDA), major aortopulmonary collateral artery (MAPCA) or in very rare cases from coronary artery-pulmonary artery fistula (CAPAF). We had coronary artery-pulmonary artery fistula (CAPAF) in 2 patients which had surgical intervention. In our first patient which was operated 10 years ago, the main pulmonary artery had a source from LMCA. In second patient, the right pulmonary artery derived from LMCA and advanced to the right lung from the posterior of the aorta and the left pulmonary artery was coming out of the PDA.

Warming climates provide many species the opportunity to colonise newly-suitable regions at higher latitudes and elevations. Despite becoming warmer, higher latitudes and elevations nevertheless offer novel climatic challenges, such as greater thermal variability and altered frequency of weather events, and these challenges exert selection on expanding populations. However, high gene flow and genetic drift during the expansion phase may limit the degree to which species can adapt to novel climatic conditions at the range front. Here we examine how landscape topographic complexity influences the opportunity for local adaptation to novel conditions during a range shift. Using RAD-seq data, we investigated whether elevation, latitude, climatic niche differentiation, and gene flow across a complex landscape were associated with signatures of adaptation during recent range expansion of the damselfly Ischnura elegans in Northeast Scotland. Our data revealed two distinct routes of colonisation, with admixture between these routes resulting in increased heterozygosity and population density. Expansion rates, assessed as directional rates of gene flow, were greater between more climatically similar sites than between climatically divergent sites. Significant genetic structure and allelic turnover was found to emerge near the range front at sites characterised by high elevation, low directional gene flow, and high spatial differentiation in climate regimes. This predictive combination of factors suggests that landscape complexity may be a prerequisite for promoting differentiation of populations, and providing opportunities for local adaptation, during rapid or contemporary range shifts

The development of precise and simple spatial interpolation methods to estimate rainfall data in ungauged locations provides not only better understating and new insights into the predictive hydrological models but also improves the accuracy of these models. In this Scientific Briefing a new approach for rainfall spatial interpolation in Luxembourgian case study has been introduced. The method used here is based on a Fuzzy C-Means (FCM) clustering method. In the normal FCM procedure, there are a lot of available data and each data point belongs to a cluster, with a membership degree [0 1], i.e. the data points clustered in an iterative process, whereas in our methodology the center of clusters has been determined first and then random data will be generated around cluster centers. Therefore, this approach is called inverse FCM (i-FCM) from here on. In order to calibrate and validate the new spatial interpolation method four rain gauges in Luxembourg (3 for calibration and one for validation) with 10 years of measured data were used and consequently the rainfall for ungauged locations were estimated. The results show that the i-FCM method can be applied with acceptable accuracy in validation rain gauge with values for R2 and RMSE of 0.92 and 12 mm, respectively, on monthly time scale and 0.84 and 1.8 mm on daily time scale.

We have recorded the Huntington's disease patient's gait videos at the5 years. It's treatment with memantine prevented the progression of Clinical symptom. It is recognized to be improved blood flow image in front-temporal lobe of IMP-SPECT.

Immunohistochemical studies have revealed that the tumor of a patient with basal cell carcinoma exhibited activation of the Hedgehog and Wnt/β-catenin signaling pathways. The glioma-associated oncogene1 overexpression leads to transcriptional activation making it an attractive molecular target in anticancer therapies due to the main downstream effectors of the cascade.

HHybridization in Aconitum is a widespread phenomenon. However, the introgression between the diploid and tetraploid species is rare. We studied species of different ploidy in a mountain hybrid zone in the Tatra Mts (West Carpathians). In this paper, we aimed to identify the extent of introgressive hybridization using PCR-ISSR fingerprinting and chloroplast DNA (cpDNA) sequencing. The diploid and tetraploid species had different cpDNA haplotypes, and the triploid hybrid was stabilized on the tetraploid level. ISSR markers showed the locally pervasive introgression, but genetic introgressants were not morphologically changed. Principal Coordinates Analysis, NeighborNet clustering, and Bayesian inference showed close genetic links between individuals in the same population but populations were significantly genetically differentiated (FST = 0.129, p < 0.001). A genetic model of introgression via the triploid bridge was proposed. Genetic introgression does not seemingly pose a threat to species taxonomic identity. The genetic differences between the same species in different populations advocate for a web-of-life than a biological species concept. Genetic introgressants in the isolated mountain populations make each of them genetically unique.

Understanding how multifactorial fluctuating environments affect species and communities remains one of the major challenges in ecology. Here, we use field experiments and simulations to assess the influence of nonlinear effects and spatial covariation of two important climate variables – warming and sediment deposition – on the biomass and photosynthetic activity of rocky intertidal biofilm. Simulations stemming from an experimentally derived response surface showed how the degree and direction of spatial covariation between warming and sediment deposition ultimately determined the nonlinear response of biofilm biomass (but not photosynthetic activity) to fluctuating levels of the two climate variables. Experimental results corroborated these predictions, probing the buffering effect of negative spatial covariation against extreme levels of warming and sediment deposition. Together, these results indicate that consideration of local-scale patterns of covariation between climate drivers can improve our understanding and ability to predict ecological responses to ongoing and future changes in Earth’s climate.

Background: Chronic pulmonary infection is the leading cause of mortality and morbidity in patients with cystic fibrosis (CF). The most common pathogens isolated in CF are Staphylococcus aureus and Pseudomonas aeruginosa (P. aeruginosa). Chronic infection of P. aeruginosa and MRSA are associated with worse survival and antibiotic eradication treatment is recommended for both. This study evaluates the efficacy of intravenous (IV) vs. non-IV antibiotics in the eradication of P. aeruginosa and MRSA. Methods: This was a single-center retrospective study at a large CF center. All respiratory specimen cultures of 309 CF patients and eradication regimens between 2015-2019 were reviewed. The primary analysis was the comparison of the percentage of successful eradication after receiving IV and non-IV eradication regimens. Demographic and clinical risk factors for eradication failure were also analyzed. Results: 102 patients with P. aeruginosa isolations and 48 patients with MRSA were analyzed. At one year, 21.6% in P. aeruginosa group and 35.4% in MRSA group were successfully eradicated. There was not any statistically significant difference between IV vs. non-IV antibiotic regimens on eradication in either group. Additionally, none of the clinical risk factors was significantly associated with eradication failure in P. aeruginosa and MRSA groups. Conclusion: In the eradication of P. aeruginosa and MRSA, IV and non-IV treatment regimens did not show any superiority to one another. Non-parenteral eradication could be a better option in eradication considering the cost-effectiveness and the treatment burden of IV treatments due to hospitalization and the need for IV access.

Understanding and preserving intra-specific diversity (ISD) is important for species conservation. However, ISD units do not have taxonomic standards and are not universally recognized. The terminology used to describe ISD is varied and often used ambiguously. We compared classical and authoritative definitions of terms used to describe ISD with terms used in recent studies of three fish taxa: sticklebacks (Gasterosteidae), Pacific salmon and trout (Oncorhynchus spp., “PST”), and lampreys (Petromyzontiformes). Our review revealed the terminological ambiguity of “races” and “subspecies”, found similar definitions of “subspecies” and “ecotype”, and of “ecotype” and “reaction norms”. “Species pairs” describes two phenotypes; however, in some situations more than one phenotype may occur. “Ecotype” was originally used to describe patterns in genes and ecology, and recent studies employing this term tend to report a genetic basis in ISD. Ecotype is used most frequently in genetic- and evolution-based journals. By contrast, “life history” includes biological parameters that affect population growth and decline, and this term tends to be used in organismal- and ecology-based journals. When the genetic or demographic components of ISD are not well understood, a conservative approach would be to refer to expressions of this diversity as “phenotypes”. The nature of human interests in particular taxa could influence how these organisms are studied, and hence the ways in which their ISD is understood, described, and conserved.

Pediatric palliative care (PPC) is an active and total approach to the care of children with life-limiting conditions and to their families. PPC programs provide ongoing care for children with medical complexity (CMC), many of whom will reach adulthood. The aim of the study is to describe a population of CMC afferent in 4 months to the Intermediate Care Unit of a tertiary referral hospital for southern and central Italy. We enrolled all CMC patients admitted at our unit in 4 randomized months. We registered pathologies and different categories of childhood diseases, devices and needs, hospitalization and home care plan. Among 195 admitted to our unit, 87 CMC were included. Median age was 9 (0.1 – 35.7) years. The main pathologies recorded were neuromuscular, neurological, respiratory, metabolic, malformative, genetic syndromes and outcomes of prematurity. Comorbidity made by respiratory, digestive, neurological, cardiac and urological involvement was present in a high percentage of cases. Among our patients, only 24 hadn’t any devices. The average length of hospitalization was 7.0 (1.0 – 270.0) days with 2 (1.0 – 7.0) admissions per year for patient. Home care activation was not required for only 24 of 87 patients. Children eligible for CPP are increasing and their survival results in a rise in comorbidities and special needs demanding multi-level interventions. Respiratory symptoms are the most recurrent observed demonstrating the need for an expert in CPP to have respiratory skills. Sharing data and knowledge of CMC needs may help to improve care coordination and interventions.

In this note, we consider a modified thin-film equation including a strong damping term together with a non-local source term. The problem is considered under the periodic boundary conditions and a finite time blow-up result is established for the case of positive initial energy. Also a lower bound estimate for the blow-up time is obtained.

We present an alternative perturbational approach free of basis set superposition error (BSSE) within the framework of the Chemical Hamiltonian Approach (CHA). The new formulation (CHA-S-MP2) is based on canonic (and orthogonal) CHA orbitals obtained from a hermitized CHA Fock operator. The final expression shows a considerable simplification of the method as compared to the previous CHA-MP2 formalism. In the present formulation only two four-index transformations are necessary so that the computational cost of the CHA-S-MP2 calculation is just twice that of a conventional uncorrected MP2 calculation. Also, contrary to the counterpoise method, the computational cost doesn’t depend on the number of interacting fragments. Numerical full geometry optimizations of water and hydrogen fluoride dimers and potential energy surfaces for helium and argon dimers for several basis sets are presented. The present method is compared to both the counterpoise and previous CHA-MP2 BSSE correction schemes, showing a remarkable agreement between all three methods. However, the wrong behavior using the aug-cc-pVDZ basis set indicates that the present method is not as robust as the original non-hermitian CHA-MP2 formulation.

With many plant-pollinator interactions undergoing change, we require a better understanding of how the addition of new interacting partners, such as antagonists, can affect plant reproduction. One such group of antagonistic floral visitors, nectar robbers, can deplete plants of nectar rewards without contributing to pollination. The addition of nectar robbing to the floral visitor assemblage could therefore have costs to the plant´s reproductive output. We focus on a recent plant colonist, Digitalis purpurea, a plant that in its native range is rarely robbed, but experiences intense nectar robbing in areas it has been introduced to. Here, we test the costs to reproduction following experimental nectar robbing. To identify any changes in the behaviour of the principal pollinators in response to nectar robbing, we measured visitation rates, visit duration, proportion of flowers visited and rate of rejection of inflorescences. To find the effects of robbing on fitness, we used proxies for female and male components of reproductive output, by measuring the seeds produced per fruit and the pollen export respectively. Nectar robbing significantly reduced the rate of visitation and lengths of visits by bumblebees. Additionally, bumblebees visited a lower proportion of flowers on an inflorescence that had robbed flowers. We found that flowers in the robbed treatment produced significantly fewer seeds per fruit on average but did not export fewer pollen grains. Our finding that robbing leads to reduced seed production could be due to fewer and shorter visits to flowers leading to less effective pollination. We discuss the potential consequences of new pollinator environments, such as exposure to nectar robbing, for plant reproduction.

For treating both relativistic effect and electron correlation, the spin-free exact two-component and spin-dependent first-order Douglas-Kroll-Hess (sf-X2C-so-DKH1) Hamiltonian and the state-interaction (SI) method are combined to calculate the spin-orbit coupling (SOC) on multi-configuration electron correlation theory. Here, SOC is evaluated via SI among the spin-free states from the complete active space self-consistent field (CASSCF) calculation, and the dynamic electron correlation could be reckoned via the high-level multi-reference electron correlation method. Work equations to evaluate SOC matrix elements over spin-adapted Gelfand states in the framework of the graphic unitary group approach (GUGA) are presented. Benchmark calculations have verified the validity of the present implementation. As a pilot application, the internally contracted MRCI (icMRCI) with the inclusion of SOC calculation produces the reasonable equilibrium bond length and the harmonic vibrational frequency of the ground state of AuO, as well as the transition energy of $X^2\Pi_{3/2} \leftarrow ^2\Pi_{1/2}$.

A novel integrated rotary reactor for NOx reduction by CO and air preheating (iNA reactor) was proposed. NOx removal performance was investigated in a fixed-bed reactor, which was used to simulate the working conditions change in iNA reactor. Lab-synthesized Cu/FeCeOx were used as catalyst. Two different modes were tested with iNA reactor: short cycles and long cycles. Excellent NOx removal efficiencies of over 95% and 90% for short cycles and long cycles were observed in iNA reactor. Moreover, compared with the constant-temperature rotary reactor, better H2O and SO2 resistances were also found in iNA reactor. The reaction mechanism was proposed based on in-situ DRIFT study. NOx was stored as nitrates in the adsorption zone, and then decomposed rapidly by both high temperatures and CO, leading to the deep catalyst regeneration. Therefore, temperature swinging and the feed of CO were key to having high iNA reactor performance for NOx removal.

The nitration of chlorobenzene with concentrated mixed acids is a fast and highly exothermic process, which suffers from considerable mass transfer resistance and poor heat transfer rates. The reaction kinetics has not been thoroughly reported before. In this work, a continuous-flow microreactor system and a homogeneous reaction condition were proposed to obtain accurate chlorobenzene nitration kinetics data at high mixed acid concentrations. A general model for predicting the observed reaction rate constants was established. With a new method for estimating the equilibria associated with HNO3 in aqueous sulfuric acid, the rate constants based on nitronium ion and activation energies were obtained. Compared with batch reactors, the continuous-flow microreactor system allows for a sufficient heat transfer efficiency and accurate residence time control, making it possible to study the reaction performance more quickly and sensitively. This work may provide a reliable reference for the kinetic study of similar processes.

Optimal tip sonication settings, namely tip position, input power, and pulse durations, are necessary for temperature sensitive procedures like preparation of viable cell extract. In this paper, the optimum tip immersion depth (20-30% height below the liquid surface) is estimated which ensures maximum mixing thereby enhancing thermal dissipation of local cavitation hotspots. A finite element (FE) heat transfer model is presented, validated experimentally with (R2 > 97%) and used to observe the effect of temperature rise on cell extract performance of E. coli BL21 DE3 star strain and estimate the temperature threshold. Relative yields in the top 10% are observed for solution temperatures maintained below 32°C; this reduces below 50% relative yield at temperatures above 47°C. A generalized workflow for direct simulation using the COMSOL code as well as master plots for estimation of sonication parameters (power input and pulse settings) is also presented.

Clarity as to the role of metal identity and oxidation state in effecting redox and acid-catalyzed turnovers is oftentimes precluded by a high degree of heterogeneity in site speciation, a limitation that can be overcome through the use of well-defined poly-metal clusters hosted by metal organic framework materials- accomplished in the present case using MIL-100(M) for the low temperature oxidation of methane with N2O. Transient kinetic data point to a) methoxy species mediating methane conversion, b) partial and deep oxidation occurring over metal sites distinct in oxidation state, c) chromium clusters amplifying the propensity toward C-C bond formation, and d) the relative velocity of propagation of water and methanol concentration fronts playing a determinative role in maximizing C2 oxygenate selectivity. The study captures the utility of using classes of materials inherently endowed with a high level of definition and uniformity in advancing the elucidation of structure-catalytic property relationships.

Portal venous gas can be detected by a bedside point of care ultrasound examination. We present the case of a 73-year-old female with advanced ischemic cardiomyopathy.

Title

Background：There is an increasing attention on miRNAs because of their functional effect on polarization of CD4+ T cells. This study explores the mechanism of miR-493-5p regulating Th9 cell differentiation in allergic asthma. Methods: The allergic airway inflammation is induced by Ovalbumin(OVA)in mice. CD4+ T cells from normal mice are cultured under Th9 cell conditions. IL-9 levels in mice and CD4+T cells are analyzed by RT-qPCR, ELISA, flow cytometry and western blot. The miR-493-5p levels in mice and cells are detected by RT-qPCR. The interaction between FOXO1 and miR-493-5p is predicted by TargetScan and confirmed by dual luciferase assay. The pathological state is evaluated by H&E staining and Lung resistance is measured in the allergic mice treated with miR-493-5p agomiR before stimulation. Results: The miR-493-5p expression in OVA-induced mice decreases significantly, accompanied by a significant upregulation in IL-9, IRF4 and FOXO1 expression and proportion of CD4+Th9 cells. MiR-493-5p mimic inhibits the expression of IL-9, IRF4 and FOXO1 and Th9 cell differentiation, while the inhibitor promotes these effects. MiR-493-5p mimic represses FOXO1 expression through interacting with 3’UTR of FOXO1 mRNA. The rescue experiment proves that miR-493-5p regulates the differentiation of Th9 cell and the expression of IL-9 by targeting FOXO1. In addition, we find that miR-493-5p agomiR treatment inhibits the FOXO1, IL-9 and IRF4 expression, decreases the proportion of CD4+ Th9 cells, alleviates the pathological state of lung tissue and airway hyperreactivity in OVA-induced asthma mice. Conclusions: Our study confirmed that miR-493-5p inhibited Th9 cell differentiation in allergic asthma by targeting FOXO1.

Multisystem inflammatory syndrome in children (MIS-C) associated with SARS-CoV-2 infection with clinical features of Kawasaki-like disease was reported in various pediatric centers in late April 2020. Currently, cases have increased throughout the world with a range of manifestations from less to greater severity. However, hemophagocytosis has not been described in patients with MIS-C. We describe two infants diagnosed with MIS-C who presented Macrophage Activation Syndrome (MAS) with hemophagocytosis documented in the bone marrow. MIS-C can be complicated with MAS, the key features for diagnosis are splenomegaly, hypofibrinogenemia, hypertriglyceridemia and bone marrow hemophagocytosis. Cytokine storm and MAS in MIS-C may represent part of the spectrum of the disease and HScore could be of value in order to give timely and aggressive treatment.
