Patients undergoing dialysis have a high incidence of fracture, and early diagnosis is important. We report seven cases of closed rib or upper-limb fractures diagnosed by bedside ultrasonography during maintenance hemodialysis sessions and describe relevant clinical characteristics.We identified seven patients who were injured by falls in their homes. No injuries occurred on the day of dialysis. Five of the 7 patients did not visit the emergency room. All patients complained of persistent unexplained pain during a regular hemodialysis session. Ultrasonography (US) was performed during dialysis sessions, without any reports of pain. Before US evaluation, the sensitivity of radiography for diagnosis of fracture was 25%, while the sensitivity of US was 100%. Co...

Abstract Converting CO2 into enhanced Li-storage materials is significant for meeting the challenges of both ever-increasing greenhouse gas and unsatisfactory energy-density of Li-ion battery. Here, a novel silicothermic reaction is developed for reduction of CO2 with Ni-activated Si into graphitic carbon (GC) in autoclave, producing well-dispersed GC-Si composites (SGC). To realize the reaction, Ni crystals are pre-anchored on Si surface, which is demonstrated for not only lowering the reaction temperature by enhancing the absorption of CO2, and suppressing the formation of inert SiC, but also facilitating the graphitization of generated carbon. Analysis of the kinetic process and cycling stability confirm the SGC electrode exhibits better Li-ion storage pe...

A study was done to measure the saccharose flux permeating through the oil layer of the dispersed vesicular globules in a series of W/O/W-type multiple emulsions, considering in connection with the effect of entrapped invertase on the hydrolytic activity in the vesicular globules. The W/O/W emulsions containing a definite quantity of invertase in the inner aqueous phase of the globules were prepared using a mixture of Span 80 and SDS, and were dialyzed against an aqueous solution of 0.1 M saccharose for over 10 days at 25°C. Thus, it was possible to follow an increasing pattern of reducing sugar with each sample in the dialysis container according to the hydrolysis of saccharose, which was diffusing into the inner aqueous phase from the outer aqueous medium...

Many Collect ive Adaptive Systems (CASs) exist in nature: think of ant colonies, where large collectives of ants operate autonomously but interact with other ants and the environment to provide resilient global behaviors that sustain their colony. Following scientific studies that were aimed at understanding and predicting the evolution of these systems, and fueled by technological advances, research has started to investigate CAS engineering: the methods, tools, and techniques for building CASs. This naturally leads to a vision where collectives of humans and computational elements, situated both in the digital and physical worlds, collaborate to give rise to "intelligent" collective behavior supporting novel kinds of applications and services. Humans can b...

Identification of an Interaction between the TPα and TPβ Isoforms of the Human Thromboxane A2 Receptor with Protein Kinase C-related Kinase (PRK) 1: IMPLICATIONS FOR PROSTATE CANCERJournal of Biological ChemistryVol. 286Issue 17PreviewIn humans, thromboxane (TX) A2 signals through the TPα and TPβ isoforms of the TXA2 receptor or TP. Here, the RhoA effector protein kinase C-related kinase (PRK) 1 was identified as an interactant of both TPα and ΤPβ involving common and unique sequences within their respective C-terminal (C)-tail domains and the kinase domain of PRK1 (PRK1640–942). Although the interaction with PRK1 is constitutive, agonist activation of TPα/TPβ did not regulate the complex per se but enhanced PRK1 activation leading to phosphorylat...

Abstract This review attempts to explain why consuming extra myo inositol (Ins), an essential component of membrane phospholipids, is often beneficial for patients with conditions characterised by insulin resistance, non-alcoholic fatty liver disease and endoplasmic reticulum (ER) stress. For decades we assumed that most human diets provide an adequate Ins supply, but newer evidence suggests that increasing Ins intake ameliorates several disorders, including polycystic ovary syndrome, gestational diabetes, metabolic syndrome, poor sperm development and retinopathy of prematurity. Proposed explanations often suggest functional enhancement of minor facets of Ins Biology such as insulin signalling through putative inositol-containing ‘mediators’, but offer ...

Glass ceramic restorations are wide used in dental practice due to their advantages as life-like appearance, excellent biocompatibility, chemical inertness, close abrasion resistance to enamel, but their most common mechanical complications are chipping and catastrophic fracture. The purpose of the study was to evaluate monolithic ceramic posterior crowns with anatomical design, achieved by hot-pressed glass ceramics, without filler Cergo (Degudent) and leucite reinforced Vita PM9 (Vita) by experimental analyses, in order to study their fracture behavior under compressive load. The modes of fracture will be correlated with the type of material, fracture load and displacement magnitude. For the experiments complete crown preparation were made on a first upper...

Abstract Background Soil salinization and alkalinization are the main factors that affect the agricultural productivity. Evaluating the persistence of the compound material applied in field soils is an important part of the regulation of the responses of cotton to saline and alkaline stresses. Result To determine the molecular effects of compound material on the cotton’s responses to saline stress and alkaline stress, cotton was planted in the salinized soil (NaCl 8 g kg − 1 ) and alkalized soil (Na 2 CO 3 8 g kg − 1 ) after application of the compound material, and ion content, physiological characteristics, and transcription of new cotton leaves at flowering and boll-forming stage were analyzed. The results showed that compared with saline stress, al...

Chromosomal instability (CIN), the increasing rate in which cells acquire new chromosomal alterations, is one of the hallmarks of cancer. Many studies highlighted CIN as an important mechanism in the origin, progression, and relapse of acute myeloid leukemia (AML). The ambivalent feature of CIN as a cancer-promoting or cancer-suppressing mechanism might explain the prognostic variability. The latter, however, is described in very few studies. This review highlights the important CIN mechanisms in AML, showing that CIN signatures can occur largely in all the three major AML types (de novo AML, secondary-AML, and therapy-related-AML). CIN features in AML could also be age-related and reflect the heterogeneity of the disease. Although most of these abnormalitie...

Congenital heart defects and skeletal malformations syndrome (CHDSKM) is a rare autosomal dominant disorder characterized by congenital heart disease, skeletal abnormalities, and failure to thrive. CHDSKM is caused by germline mutations in ABL1. To date, three variants have been in association with CHDSKM. In this study, we describe three de novo missense variants, c.407C>T (p.Thr136Met), c.746C>T (p.Pro249Leu), and c.1573G>A (p.Val525Met), and one recurrent variant, c.1066G>A (p.Ala356Thr), in six patients, thereby expanding the phenotypic spectrum of CHDSKM to include hearing impairment, lipodystrophy-like features, renal hypoplasia, and distinct ocular abnormalities. Functional investigation of the three novel variants showed an increased ABL1 kinase acti...

Abstract This work aims to investigate the influence of the orientation and microtexture of columnar grains on the fatigue crack growth of a Ti-6.5Al-2Zr-Mo-V titanium alloy fabricated by directed energy deposition. In this paper, the fatigue crack growth rate test in three sampling directions in a directed energy deposited Ti-6.5Al-2Zr-Mo-V titanium alloy using compact specimens was carried out. The crack length was measured visually, and the fatigue crack growth rate of the stable crack growth stage was obtained. During the test, the influence of the microstructure on the crack growth was directly observed. In addition, the complete crack front shape was indicated on the fracture surface by the marker load technique, and the crack growth behavior was obtai...

Abstract Background Development of sensitive and specific imaging approaches for the detection of ovarian cancer holds great promise for improving the therapeutic efficacy and the lifespan of the patients. Results In this study, manganese-nitrogen doped carbon nanosheets (Mn-N-CNSs) coupled with Anti-HE4 monoclonal antibody (Mn-N-CNSs@Anti-HE4) were synthesized for the specific and targeted fluorescence/MR dual-modal imaging of ovarian carcinoma. The prepared Mn-N-CNSs revealed excellent aqueous dispersity, good colloidal stability, great optical properties and high longtudinal relaxivity rate (r 1 = 10.30 mM −1 s −1 ). Encouraged by the tunable photoluminiscence of the nanoprobe and Anti-HE4 targeting ligand, the ovarian carcinoma cells were specificall...

The multi-year (2015–2017) drought in the South West of the Western Cape (SWC) caused a severe water shortage in the summer of 2017–2018, with damaging impacts on the local and regional economy, and Cape Town being in the news one of the first major cities to potentially run out of water. Here, we assess the links between the rainfall deficits during the drought and (a) large scale circulation patterns, (b) moisture transport, and (c) convective available potential energy (CAPE). We used self-organising maps (SOM) analysis to classify daily ERA-interim 850 hPa geopotential height for the period 1979–2017 (March–October) into synoptic types. This allowed us to identify the dominant synoptic states over Southern Africa that influence the local climate ...

A primary limitation of Direct Sequence Code Division Multiple Access DS-CDMA link performance and system capacity is multiple access interference (MAI). To examine the performance of CDMA systems in the presence of MAI, i.e., in a multiuser environment, several works assumed that the interference can be approximated by a Gaussian random variable. In this paper, we first develop a new and simple approach to characterize the MAI in a multiuser system. In addition to statistically quantifying the MAI power, the paper also proposes a statistical model for both variance and mean of the MAI for synchronous and asynchronous CDMA transmission. We show that the MAI probability density function (PDF) is Gaussian for the equal-received-energy case and validate it by c...

In order to demonstrate the historical image of a city, historical texts and field surveys are usually used. Field surveys and archeological excavations seem to be the only accessible options when there is a shortage of reliable sources and written texts. The question raised in this study is: how can the historical evolution of a city be described before any archeological surmising if there are no reliable historical texts. The purpose of this article is to show the gradual formation of urban texture on the basis of the urban morphology. The historical city of Boshruyeh has been studied by using the descriptive-analytic method. In this regard the historical image of this city has been portrayed by considering the literature and particularly Norberg-Schulz's ...

Aims Natriuretic peptide (NP) levels are routinely employed as useful diagnostic and prognostic tools in the evaluation of patients with heart failure (HF). As hospitalization is the major consumer of healthcare resources, the prognostic power of admission NPs with regard to the duration of hospitalization deserves further investigation. Methods and results We assessed retrospectively the association between NP values sampled shortly following unplanned admission and the duration of hospitalization in 2978 patients admitted to a cardiology department. Duration of hospitalization (hours) and survival were determined by interrogation of the electronic medical records system. Associations with peptide levels were estimated using regression models and receiver o...

Cesium-based inorganic perovskite solar cells (PSCs) are paid more attention because of their potential thermal stability. However, prevalent salt-doped 2,2',7,7'-tetrakis(N,N-dipmethoxyphenylamine)9,9'-spirobifluorene (Spiro-OMeTAD) as hole-transport materials (HTMs) for a high-efficiency inorganic device has an unfortunate defective thermal stability. In this study, we apply poly (3-hexylthiophene-2,5-diyl) (P3HT) as the HTM and design all-inorganic PSCs with an indium tin oxide (ITO)/SnO2/LiF/CsPbI3-xBrx/P3HT/Au structure. As a result, the CsPbI3-xBrx PSCs achieve an excellent performance of 15.84%. The P3HT HTM-based device exhibits good photo-stability, maintaining ∼80% of their initial power conversion efficiency over 280 h under one Sun irradiation....

C0S patients have symptoms of chronic venous disorders (CVDs), though an anatomical or pathophysiological explanation is lacking. C0 and C1 classified lower limbs can present with valve incompetence from the second to sixth generation of tributaries of saphenous veins despite the absence of a detectable saphenous truncal reflux. We hypothesized that C0S venous symptoms could stem from the second to sixth generation of saphenous tributaries and small veins that are not connected to the saphenous system. The aim was to explore these veins in C0S subjects and compare them with asymptomatic C0A subjects.This was an open, controlled study enrolling 36 subjects, where C0S patients (N.=18) were compared with asymptomatic C0A subjects (N.=18). The VAS (visual analog...

The study presents a novel molten salt assisted autocombustion synthesis of SrFe 12−x Al x O 19 particles. The extrinsic magnetic properties such as coercivity and the remanence of sintered M-type ferrites are highly dependent on the microstructure viz. morphology and size, of the ferrite particles. The control of the microstructures of ferrite particles is usually achieved via control nucleation and grain growth process. In this study, NaCl salt was used to control the crystal shape and size of Al 3+ doped SrFe 12−x Al x O 19 particles. The presented novel method couples advantage of deriving homogenized particles via auctocombustion first and later sintering in the presence of NaCl salt. Highly dispersed, homogeneous, and hexagonal shaped SrFe 12−x A...

Background. Sinonasal undifferentiated carcinoma (SNUC) is an uncommon malignancy associated with poor prognosis. The optimal treatment approach for SNUC has not been established was performed. Methods. A retrospective review of all patients with SNUC seen at the Peter MacCallum Cancer Centre over a 12-year period. Results. Ten patients with SNUC were identified, with nine having locally advanced disease (T4). Seven were treated with three cycles of platinum and 5-fluorouracil followed by radiation with two cycles of concurrent platinum. In these seven patients, the 2-year progress on-free survival was 43% (95% CI, 11% to 82%) and 2-year overall survival was 64% (95% CI, 23% to 91%). One patient with a T1N0 nasal cavity tumor treated with radiation alone has...

A modified seed mounting geometry is proposed, aiming to improve the distribution homogeneity of the supersaturation on the crystal face during the growth of ammonium dihydrogen phosphate (NH4H2PO4, ADP) crystals. To evaluate the modification, three dimension transient numerical simulation of flow and solute transfer involved in the growth of ADP crystals have been performed. The effects of flow on the surface supersaturation distribution is analyzed in detail. Compared with the ordinary seed mounting geometry, the modified geometry is able to suppress the formation of flow stagnation regions near the prismatic surface and improve the magnitude and the distribution homogeneity of the supersaturation. Particularly even at a lower rotation rate (ω = 30 rpm), ...

This paper presents results from an experimental evaluation on the pre- and post-buckling behavior of 12 steel wide-flange cantilever columns under axial load and lateral drift demands. The influence of several loading and geometric parameters, including the cross-sectional local web and flange slenderness ratios, applied axial load, and lateral and axial loading history on the performance of these columns is thoroughly examined. The test data indicate that cross-sectional local buckling is highly asymmetric in steel columns under variable axial load. A relatively high compressive axial load can significantly compromise the steel column seismic stability and ductility, but this also depends on the imposed lateral loading history. The AISC axial load–bendin...

Galectin-1, a beta-galactoside binding protein that can occur as both a monomer and a homodimer, binds to leucocyte membrane antigens such as CD7, CD43, and CD45, and has immune-regulatory functions in several animal models of autoimmune disease. However, its mechanism of action is only partially understood. In this study, a marked increase in IL-10 mRNA and protein levels was demonstrated in non-activated and activated CD4(+) and CD8(+) T-cells, following treatment with a high concentration (dimeric form), but not a low concentration (monomeric form), of recombinant galectin-1 protein. IL-10 is known to suppress TH1 type immune responses and upregulation of IL-10 may thus contribute to the immune-regulatory function of galectin-1. Galectin-1 was strongly ex...

The global financial integration (GFI) has augmented the international financial flow movement without restructuring global financial regulatory system (GFRS). The goal of the global financial regulatory system is to maintain global level stability. In GFRS, the financial stability board (FSB) is responsible for the macro-prudential regulation and the micro-prudential regulation is monitored by international standard setting bodies (SSBs), international financial institutions (IMF and World Bank) and national financial regulators. These micro-prudential regulation and macro-prudential regulation are non-binding in the legal sense. However, these regulations examine as a standard of efficiency. The member nations are strictly implementing the standards becaus...

Since the late 1970s. Film Studies as a discipline within North America has come to display many of the signs of paradigmatic coherence. Polemics within the field are increasingly rooted in shared sets of terms and premises, and the theoretical developments produced over the last decade in influential journals such as Screen have trickled down to undergraduate text-books, and laterally into such hitherto isolated enterprises as the writing of corporate histories. For a discipline which suffered for decades from an eclecticism and discontinuity with few parallels elsewhere, this new coherence has brought a sense of community to the field, and an elusive academic respectability. At the same time, a heightened awareness of the political stakes within theoretica...

Abstract The effect of Mo on the pitting potential, dissolution kinetics, and repassivation behavior of high purity ferritic stainless steels, Fe–18%Cr–x%Mo, and austenitic stainless steels, Fe–18%Cr–12–15%Ni–x%Mo, was studied in solutions of bromide and of chloride. Large increases in the pitting potential of Fe–18%Cr–x%Mo in chloride solution were found with increasing Mo content, compared with the distinctly smaller increases in bromide solution. There was an excellent correlation between the increase in pitting potentials of ferritic alloys between Fe–18%Cr–2% and 5%Mo in the chloride and bromide solutions with the increased dissolution overvoltages in the saturated solution of dissolved products within artificial pits. Austenitic sta...

Significance Echoviruses are associated with aseptic meningitis and induce severe and sometimes fatal disease in neonates and young infants. Here, we identify the neonatal Fc receptor (FcRn) as a pan-echovirus receptor. FcRn is expressed on the surface of the human placenta, and throughout life on intestinal enterocytes, liver hepatocytes, and in the microvascular endothelial cells that line the blood–brain barrier. This pattern of expression is consistent with the organ sites targeted by echoviruses in humans, as the primary entry site of infection is the intestinal and secondary sites of infection include the liver and brain. These findings provide important insights into echovirus pathogenesis and may explain the enhanced susceptibility of neonates to e...

ABSTRACTResearch question: Sponsorship relationships can be categorized into a beginning, an ongoing, and an ending phase. Although all of these phases can be consequential for the sponsoring brand, past research mainly focuses on the beginning phase and the management of existing sponsorships, and only a few studies examine the effects of ending a sponsorship relationship. The present study addresses this gap by exploring how two types of exit (chosen vs. forced) and the exit consequences (few vs. extensive) influence consumers’ evaluations of the sponsor brand.Research methods: This research uses an experimental study (N = 202). Data were collected among supporters of a German second division soccer team.Results and findings: The results reveal that ...

Abstract The efficient manufacture of electrodes with high volumetric capacity is crucial for the rechargeable batteries for application in limited space. Hot isostatic pressing (HIP) of LiFePO4 (LFP) cathodes using a pressure of 240 MPa at 90  C is very effective for enhancing volumetric capacity. After HIP treatment, LFP cathodes can reach a density of 2.62 g cm−3, and achieve a volumetric capacity of 362 mAh cm−3, which is about twice as high as that of the conventional LFP cathodes. Especially, under the drive of isostatic pressure, the electrolyte readily infiltrate the voids among LFP particles, facilitating Li ion diffusion. LFP cathodes with the pre-infiltrated electrolyte exhibit superior rate capability and cycle performance, which maintain a ...

The interest in sustainability in the construction industry arose in the 1990s, and current studies have created models to predict environmental aspects. Previous quantitative research to investigate environmental aspects was based on the perception of specialists. The present article proposes a methodology applicable to urban infrastructure activities in order to quantify environmental aspects by applying duration and severity criteria, using calculations founded in the scientific literature. The quantitative methodology to assess environmental aspects calculated ten aspects for six construction activities based on duration and severity criteria, eliminating the judgement of the latter criterion of earlier methodologies. The results revealed five significan...

Abstract Although many SF texts proceed from the speculative premise that our species will continue to develop technologically, and hence become increasingly posthuman, our species’ continuance into even the next century is by no means assured. Rather, the Anthropocene exerts a new temporal logic; it is an age defined by an intensification of geological timescales. It is therefore noteworthy that many contemporary SF texts are ecologically interventionist and figure apocalyptic future temporalities which curtail the posthuman predilection common to the genre. This article analyses a tetrad of literary texts, written at various points during the last three decades, which summatively reveal the mutations of the (post)human temporalities figured by cli-fi tex...

Purpose The purpose of this study is to collect data that allows researchers to capture both affective and cognitive buy-in influenced by both product and product strategy targets. Design/methodology/approach Analysis of 13 salesperson interviews followed the cluster and axial coding of grounded theory interview protocol. Findings This study finds two types of buy-in that are uniquely contingent on the target, and for which are influenced by both cognitive and affective states of being. Additionally, it finds that either affective or cognitive states of being can both drive and inhibit salesperson buy-in of either target. While the targets of buy-in appear to be mutually exclusive, the cognitive nature of disconfirming evidence appears to directly inhibit bo...

The rate of performing primary percutaneous coronary intervention in patients with complex coronary artery disease is increasing. The use of percutaneous mechanical circulatory support devices provides critical periprocedural hemodynamic support. Mechanical support has increased the safety and efficacy of interventional procedures in this high-risk patient population. Predicting patient response to the selected intervention can be clinically challenging. Here we demonstrate a case where complete hemodynamic collapse during PCI was avoided by mechanical support provided by the Impella device. Further, we employ a comprehensive cardiovascular model to predict ventricular function and patient hemodynamics in response to the procedure. New computational tools ma...

Abstract This paper presents the roles of slanted cracks on the stress intensity factors (SIF) under mode I tension and bending loading. Based on the literature survey, lack of solution of SIFs of slanted cracks in plain strain plates are available. In this work, the cracks are modelled numerically using ANSYS finite element program. There are two important parameters such as slanted angles and relative crack length. SIFs at the crack tips are calculated according to domain integral method. Before the model is further used, it is validated with the existing model. It is found that the present model is well agreed with the previous model. According to finite element analysis, there are not only mode I SIFs produced but also mode II. As expected the SIFs incre...

Faults can be either conduits or retarders for fluid flow. As the presence of faults increases the risks for hydrocarbon exploration, the sealing behaviour of a fault zone has been a focus for geological studies in the past 30 years. Due to the widespread occurrence of fault zones, either in extensional or contractional regimes, knowledge about the fault sealing behaviour is of great importance to a wide spectrum of disciplines in geosciences, for instance, structural geology, geochemistry, petroleum geology, etc. Geologists have extensively studied the sealing properties of a fault zone over the last decades, ranging from fault zone architecture, fault seal types, fault seal processes, fault rock classification, research methods and controlling factors. Alt...

Release of silver ions (Ag+) is often regarded as the major cause for silver nanoparticle (AgNP) toxicity toward aquatic organisms. Nevertheless, differentiating AgNPs and Ag+ in a complicated biological matrix and their dissolution remains a bottleneck in our understanding of AgNP behavior in living organisms. Here, we directly visualized and quantified the time-dependent release of Ag+ from different sized AgNPs in an in vivo model zooplankton ( Daphnia magna). A fluorogenic Ag+ sensor was used to selectively detect and localize the released Ag+ in daphnids. We demonstrated that the ingested AgNPs were dissoluted to Ag+, which was heterogeneously distributed in daphnids with much higher concentration in the anterior gut. At dissolution equilibrium, a total...

The behavior of reinforced concrete frame with infill wall (RDP) has been studied numerically by modeling the RDP structure using the LUSAS software. The results were compared to other researchers’ results that conducted laboratory test and used SAP programs. The results of analysis using SAP show that the proposed model that subjected to load up to the maximum limit show similar behavior to the laboratory tests results in which parameters such as secant modulus for concrete and wall materials based on graphs of stress-strain relationships and a reduction in moment of inertia due to the crack of beam-column are taken into account. The model using LUSAS did not adopt this method instead applied plastic elastic material and non-linear analysis. The results o...

Les épiphanies littéraires sont des jalons qui marquent un basculement du texte au moyen d’une révélation, d’une prise de conscience ou encore d’une apparition soudaine. Cet article se penche sur les épiphanies du texte Là-Bas, premier roman du cycle de Durtal de J. K. Huysmans. Nous abordons celles-ci comme des instants décisifsdu tissu narratif inscrit dans la durée. Nous traitons ces moments-pivots du roman selon les thématiques liées de la clarté et de l’obscurité, en dégageant les occurrences de dévoilement dans lesquels le narrateur exprime un recadrage du protagoniste sur son désir. Il s’agit de montrer comment la voix narrative traite les épiphanies du texte comme des événements où une lumière se fait sur plusieurs ligne...

The aim of this study was to conduct a review of articles about tobacco or alcohol published from 1980 to 2010 in the Journal of the American Dental Association (JADA), Journal of Dental Education (JDE), and Journal of Public Health Dentistry (JPHD) in an attempt to identify trends by decade in topics relevant to oral health consequences, oral cancer linkages, and cessation counseling. NVivo qualitative analysis software was used to code abstracts using the keywords "tobacco" or "alcohol." The search identified 269 articles: tobacco=211 (78%), alcohol=58 (22%). This number represented 2.4% of the total articles published in these journals for the specified years. While the percentage of tobacco-related articles increased over this period (with highs in the 1...

We use a sample of 149 spectroscopically confirmed UV-selected galaxies at $z\sim 2$ to investigate the relative dust attenuation of the stellar continuum and the nebular emission lines. For each galaxy in the sample, at least one rest-frame optical emission line (H$\alpha$/[NII]$\lambda6583$ or [OIII]$\lambda5007$) measurement has been taken from the litterature, and 41 galaxies have additional Spitzer/MIPS 24$\mu$m observations that are used to infer infrared luminosities. We use a spectral energy distribution (SED) fitting code that predicts nebular line strengths when fitting the stellar populations of galaxies in our sample, and we perform comparisons between the predictions of our models and the observed/derived physical quantities. We find that on ave...

A B S T R A C T Style abscission was studied in detail in citrons (Citrus medica L.) and other citrus varieties. The course of style abscission was followed under orchard conditions and also in an system consisting of pistils implanted in an agar-sucrose medium and maintained at 25 C in a humid chamber. Morphological and anatomical observations carried out with the explant system revealed a prominent swelling of cell layers proximal to the separation layer prior to abscission. Tests with explants from flowers of different developmental stages showed that before the end of anthesis only the ovaries are capable of performing abscission while style abscission is possible only at a later stage, presumably after fertilization had occurred. Ethylene was able to in...

To evaluate the performance of dual-source computed tomography (DSCT) in the component analysis of all types of calculi by doing a systematic review and meta-analysis.We searched MEDLINE, Embase, Scopus, and CNKI up to February 28, 2020, for in vivo studies investigating the performance of DSCT in the component analysis of calculi. We pooled the sensitivity, specificity, and areas under the summary receiver operating characteristic (AUROC) curves using a random-effect model in the meta-analysis. Publication bias was evaluated using Deek's funnel plot asymmetry test.This analysis included a total of 37 studies in 1840 patients with 2151 calculi (462 uric acid [UA], 1383 calcium oxalate [CaOx], 55 cystine [Cys], 197 hydroxyapatite [HA], and 54 struvite [SV]). ...

Self-management, or self-care, by individuals and/or families is a critical element in chronic illness management as more care shifts to the home setting. Mobile device-enhanced health care, or mHealth, is being touted as a means to support self-care. Previous mHealth reviews examined the effect of mHealth on patient outcomes, however, none used a theoretical lens to examine the interventions themselves. The aims of this integrative review were to examine recent (e.g., last 10 years) chronic illness mHealth empiric studies and (1) categorize self-care behaviors engaged in the intervention according to the Middle-Range Theory of Self-care of Chronic Illness, and (2) conduct an analysis of gaps in self-care theory domains and behaviors utilized. Methods includ...

Mucus performs numerous protective functions in vertebrates, and in fishes may defend them against harmful organisms, although often the evidence is contradictory. The function of the mucous cocoons that many parrotfishes and wrasses sleep in, while long used as a classical example of antipredator behaviour, remains unresolved. Ectoparasitic gnathiid isopods (Gnathiidae), which feed on the blood of fish, are removed by cleaner fish during the day; however, it is unclear how parrotfish and wrasse avoid gnathiid attacks at night. To test the novel hypothesis that mucous cocoons protect against gnathiids, we exposed the coral reef parrotfish Chlorurus sordidus (Scaridae) with and without cocoons to gnathiids overnight and measured the energetic content of cocoo...

A haploid model of frequency-dependent selection and assortative mating is introduced and analyzed for the case of a single multiallelic autosomal locus. Frequency-dependent selection is due to intraspecific competition mediated by a quantitative character under stabilizing or directional selection. Assortment is induced by the same trait. We analyze the equilibrium structure and the local stability properties of all possible equilibria. In the limit of weak selection we obtain global stability properties by finding a Lyapunov function. We provide necessary and sufficient conditions for the maintenance of polymorphism in terms of the strength of stabilizing selection, intraspecific competition and assortment. Our results also include criteria for the ability...

Although empowerment is a widely used concept in health-related areas, its definition remains unclear. While there is evidence for the effectiveness of empowerment interventions in improving some psychosocial factors linked to health (e.g. patient self-care strategy, coping skills, access and effective use of health services) and some health outcomes like mental health and HIV/AIDS-related behaviour, other data appear to contradict this. Moreover, concepts, measures, and outcomes related to empowerment are operationalized in different ways. Using the case of tobacco control programmes, we wanted to explore: (a) how research on smoking reduction/prevention has conceptualized empowerment; (b) which measures and instruments have been used to assess behaviour ou...

This randomized controlled trial investigated the efficacy of Attachment and Biobehavioral Catch-up (ABC; Dozier, Bick, & Bernard, 2011) in reducing disrupted parenting behavior (affective communication errors, role/boundary confusion, fearful/disoriented, intrusive/negativity, and withdrawal) and its association with disorganized attachment. Participants were 105 mother-child dyads randomized to receive either ABC or a control intervention (a 10-session home-visiting intervention focused on improving children's cognitive abilities, gross and fine motor abilities, and language development). At the time of study enrollment, mothers were approximately 26.7 years old (SD = 7.8) and predominantly Black or African American (73.9%). At the first follow-up visit, c...

Although many public health initiatives have been implemented through collaborations with faith-based institutions, little is known about best practices for developing such programs. Using a community-based participatory approach, this case study examines the implementation of an initiative in the Bronx, New York, that is designed to educate community members about health promotion and disease management and to mobilize church members to seek equal access to health care services. The study used qualitative methods, including the collaborative development of a logic model for the initiative, focus groups, interviews, analysis of program reports, and participant observation. The paper examines three key aspects of the initiative's implementation: (1) the engag...

Fault tree analysis (FTA) has been widely utilized as a reliability evaluation technique for complex systems, such as nuclear power plants and aerospace systems. However, it is hard to obtain the crisp failure probabilities of basic events, owning to the insufficient information about some complex engineering systems. Hence, fuzzy set theory and fuzzy arithmetic operation (FAO) have been used as effective methods to analyze system reliability. However, it is cumbersome to evaluate complex systems based on FAO. To improve the evaluation efficiency, stochastic computational models are proposed in this paper to perform reliability analysis of a fuzzy system. Due to the features of Gaussian distribution in stochastic computation, a basic event’s failure possib...

Assessing risk factors exposure, such as stress in the workplace during adulthood, may contribute to detecting early signs of cognitive impairment in order to implement effective actions to improve brain health and consequently to decrease cognitive disorders later in life. In this cross-sectional study, we aimed to investigate whether work-related stress is associated with low cognitive performance in middle-aged adults from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) and whether social support mediates this relationship. Work-related stress was evaluated in 9,969 workers using the Demand-Control-Support Questionnaire. Cognitive function was assessed using the verbal fluency, trail-making version B, and delayed recall word tests. Work-rel...

Metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) is one of the most abundant, long non-coding RNAs (lncRNAs) in normal tissues. This lncRNA is highly conserved among mammalian species, and based on in vitro results, has been reported to regulate alternative pre-mRNA splicing and gene expression. However, Malat1 knockout mice develop and grow normally, and do not show alterations in alternative splicing. While MALAT1 was originally described as a prognostic marker of lung cancer metastasis, emerging evidence has linked this lncRNA to other cancers, such as breast cancer, prostate cancer, pancreatic cancer, glioma, and leukemia. The role described for MALAT1 is dependent on the cancer types and the experimental model systems. Notably, different ...

This work investigated the electrolysis of ammonium dinitramide (ADN: NH4N(NO2)2) in dimethyl sulfoxide (DMSO). Various fundamental electrolysis properties of ADN were assessed based on an electrochemical study and the associated mechanisms were examined based on a quantum chemical approach. ADN exhibited three redox peaks at −0.69, −1.16 and −1.52 V, and two oxidation peaks at 0.34 and 0.50 V (vs Ag/AgCl) at a scan rate of 50 mV s−1 during cyclic voltammetry trials with a platinum electrode. Ultraviolet-visible spectra of ADN in DMSO were also acquired to determine temporal changes under galvanostatic reduction conditions. These spectra showed that a continuous current in conjunction with an applied voltage of −1.5 V decomposed the ADN, but were u...

In this paper, we have considered a two-phase flow in a groovy curved channel. The fluid contains a uniformly distributed small particles and the flow is generated by a transient pressure gradient along the grooves. The governing equations describing the flow in the groovy curved domain are developed and the analytical solution of the complex flow field is determined using domain perturbation method. The effect of the particles on the flow is discussed through the particle relaxation time relative to the flow characteristic time. It is found that the fluid and particle velocities depend on the magnitude of particle relaxation time relative to the flow characteristic time. The effect of the grooves on the transient flow is examined in the presence of the flui...

Abstract Aim Surgery with or without chemotherapy represent the only curative option for patients with colon cancer. However, some patients refuse treatment despite the recommendation. This study aims to identify the incidence, risk factors and impact on survival associated with refusal. Methods A National Cancer Data Base (NCDB) analysis between 1998 and 2012 was performed. We identified 924,290 patients with potentially treatable colon cancer. Patients who underwent treatment were compared with patients that refused. Results 7152 patients refused surgery. On multivariable analysis, patients were more likely to refuse if they were older (OR = 1.14; 95% CI 1.14–1.15), female (OR = 1.20; 95% CI 1.12–1.28), African American (vs White, OR = 2.30; 95% ...

A total and stereospecific synthesis of cadeguomycin (1), ara-cadeguomycin (2), and 2′-deoxycadeguomycin (3) has been accomplished from the novel aglycones 2-amino-4-chloro-7H-pyrrolo[2,3-d]pyrimidine-5-carbonitrile (11) or methyl 2-amino-4-chloro-7H-pyrrolo[2,3-d]pyrimidine-5-carboxylate (13). Ring annulation of 2,6-diaminopyrimidin-4(3H)-one (6) with methyl chloro(formyl)acetate (7) in the presence of NaOAc provided a mixture of two products (8) and (9), from which the desired methyl 2-amino-3,4-dihydro-4-oxo-7H-pyrrolo[2,3-d]pyrimidine-5-carboxylate (9) was separated and converted into the key intermediates (11) and (13). Reaction of the sodium salt of (11) with 2-deoxy-3,5-di-O-p-toluoyl-α-D-erythro-pentofuranosyl chloride (14) gave the corresponding ...

Conventional inorganic mass spectrometric (MS) analysis of metals can require time-consuming and tedious sample preparation. We thus report the novel and direct characterization of metals in solid samples using an organic MS technique known as electrospray laser desorption ionization mass spectrometry (ELDI/MS). No sample pretreatment was needed, and results were rapidly obtained due to the ambient and laser-based nature of ELDI/MS. Metals from samples were desorbed and ionized by laser irradiation, after which they reacted with EDTA and then post-ionized and detected as metal-EDTA complexes. Aluminum, copper, iron, lead, nickel, and zinc from plates, foils, and coins were characterized in seconds. This study demonstrates that an ESI/MS system can be easily ...

The main purpose of this study was to investigate the seasonal variation of the uranium (U) concentration level in natural drinking water. Laser fluorimetry technique has been used for the microanalysis of uranium concentration in water samples collected from different natural sources like springs and subterranean springs of various depths. A total of 23 drinking water samples were collected based on their consumption for drinking purposes from the different areas of Pithoragarh district. Seventeen physico- chemical parameters, six heavy metals and uranium were estimated in the samples. The results showed that the average value of TDS was observed 204.65 mg/L during pre- monsoon season and 213.82 mg/L during post- monsoon season, the uranium concentration in...

Non-clear cell renal cell carcinoma (nccRCC) represents a group of multiple histologic subtypes, with different clinical outcomes and an uncertain optimal treatment. Data collected in clear cell tumors are routinely extrapolated to nccRCC, despite a different underlying biology. The Center Group for Genitourinary tumors is a network of medical oncologists from hospitals in Madrid and surrounding provinces that are focused on genitourinary tumors. A retrospective, multicenter study of the outcome of patients with nccRCC diagnosed and treated at the Center Group hospitals between 1995 and 2015 was performed. Baseline clinical features, histologic subtypes, therapeutic management and survival status were analyzed. Data was collected from 173 patients, with a me...

Abstract Introduction Cellular metabolites are generated by a complex network of biochemical reactions. This makes interpreting changes in metabolites exceptionally challenging. Objectives To develop a computational tool that integrates multiomics data at the level of reactions. Methods Changes in metabolic reactions are modeled with input from transcriptomics/proteomics measurements of enzymes and metabolomic measurements of metabolites. Results We developed SUMMER, which identified more relevant signals, key metabolic reactions, and relevant underlying biological pathways in a real-world case study. Conclusion SUMMER performs integrative analysis for data interpretation and exploration. SUMMER is freely accessible at http://summer.salk.edu and the code is ...

Epidemiological studies have established the correlations between PM2.5 and a wide variety of pulmonary diseases. However, their underlying pathogeneses have not been clearly elucidated yet. In the present study, the epithelial-mesenchymal transition (EMT) phenotype with enhanced proliferation and migration activity of human pulmonary epithelial cell line BEAS-2B was observed after exposure to low dose PM2.5 exposure (50 μg/ml) for 30 passages. Then, epithelial cells derived-exosomal micro-RNA (miRNA) and intracellular total RNA were extracted, and the differentially expressed exosomal miRNAs (DE-Exo-MiRs) as well as differentially expressed protein coding genes (DEGs) were identified by RNA sequencing (RNA-seq) and transcriptome analysis. We found that chr...

This study's purpose was to describe the journal publication process from the perspective of the nurse author. A survey was mailed to 226 nurses who had published an article during the 1-year period. A variety of clinical, research, educational and administrative nursing journals were used to select the sample. Results suggested that authors: find communicating with editors helpful; think time from acceptance to publishing is too lengthy; publish to share their information and contribute to the body of nursing knowledge rather than for career advancement; generally do not use enquiry letters; and many did not know if the journal to which they submitted was referred. Further research on the views of authors who have had manuscripts rejected would clarify whet...

In the Russian Arctic, alarming trends (shortage of nomadic Indigenous women, high reproductive loss, child mortality rates) indicate long-term changes towards demographic decline. This study aimed at comparing some indicators of the reproductive health (childbirth rates, number of pregnancies, pregnancy loss) of Indigenous and non-Indigenous women in the exploration of cultural and social factors influencing reproductive behaviour. A multidisciplinary approach draws on methods of medicine, sociology and health economics. It includes data of the women's reproductive health collected from surveys of 879 women (of whom 627 were Indigenous) during expeditions to the settlements and the tundra of the Yamal-Nenets Autonomous Okrug in 2013-2019. In the tundra, 66....

α1-6 Fucosyltransferase (α1-6 FucT) catalyzes the transfer of fucose to innermost GlcNAc in N-glycans. This structure on α-fetoprotein has been clinically used for early diagnosis of hepatocellular carcinoma. In this study, expression of α1-6 FucT was investigated in rat and human hepatocarcinogenesis and biological significance of α1-6 FucT on hepatoma was investigated in terms of metastasis. While α1-6 FucT was scarcely detected in normal liver, it was enhanced in LEC rat hepatoma, but not in their surrounding tissues. In contrast, high expression of α1-6 FucT mRNA was observed in human liver cirrhosis tissues as well as in hepatoma tissues. We established human hepatoma cell lines which express high levels of α1-6 FucT by transfection of α1-6 Fuc...

Brain adverse structural changes, especially the atrophy of gray matter, are inevitable in aging. Fortunately, the human brain is plastic throughout its entire life. The current cross-section study aimed to investigate whether long-term Tai Chi exercise could slow gray matter atrophy and explore the possible links among gray matter volume (GMV), long-term Tai Chi experience and emotional stability in a sequential risk-taking task by using voxel-based morphometry (VBM). Elders with long-term Tai Chi experience and controls, who were matched to Tai Chi group in age, gender, physical activity level, participated in the study. A T1-weighted multiplanar reconstruction (MPR) sequence was acquired for each participant. Behaviorally, the Tai Chi group showed higher ...

Aspergillus fumigatus is the commonest cause of pulmonary aspergillosis; however, a recently developed molecular genetic technique identified A. lentulus as a sibling species. Most of the isolates were found in solid organ recipients, often associated with a fatal outcome. Moreover, there is concern that A. lentulus has low susceptibility to multiple antifungal agents. Herein, we report an adult immunocompromised patient with proven invasive pulmonary aspergillosis (IPA) caused by A. lentulus, which was identified through molecular genetic analysis. The patient was diagnosed with IPA by bronchoscopy 3 weeks after initiating systemic corticosteroid therapy for anti-neutrophil cytoplasmic antibody-associated vasculitis. The clinical course of IPA due to A. len...

Abstract SiOx-based anode materials suffer from inherent defects of volume expansion, high initial capacity loss, and the huge electron and ion resistance in the unstable solid electrolyte interphase layer impede their commercialization. Surface coating is the most prevalent strategy for resolving the key concerns. In this paper, we present a dual-shell coating structural composite (denoted as SiOx@TiO2@C) through a two-step process. By introducing a high-quality anatase-phase TiO2 layer, a highly stable interface and decreased resistance to electron and ion diffusion of composite are achieved and investigated systematically. Additionally, the side reactivity is studied firstly. Moreover, the enhanced safety of the electrode is evaluated. The as-prepared com...

Librarians and graphic designers have a lot in common. Both are information professionals that offer means or cues to help users navigate, understand and solve a problem within a certain space. Without the librarian, the library space itself becomes the interface where users are offered signage to problem-solve intuitively. Because of this, effective communication via signage and wayfinding becomes imperative to the library user experience. By empathizing with our patrons and clearly articulating what the problem is, it is possible to anticipate user needs, address them by utilizing the design-thinking process, and prototype solutions like a graphic designer. However, this is not a permanent, one-time process, and it will need to be repeated whenever the nee...

We assessed the willingness of gay and bisexual men, who have high rates of anal cancer that might be prevented through regular screening, to receive anal Papanicolaou tests.We surveyed a national sample of men aged 18 to 59 years who self-identified as gay (n = 236) or bisexual (n = 70).Most respondents were willing to accept free screening (83%), but fewer would pay for the test (31%; McNemar's chi(2) = 158.02; P < .001). Willingness to pay for screening was higher among men who reported greater worry about getting anal cancer (OR [odds ratio] = 1.70; 95% confidence interval [CI] = 1.06, 2.72), higher perceived likelihood of anal cancer (OR = 1.88; 95% CI = 1.18, 2.99), and higher income (OR = 2.17; 95% CI = 1.18, 3.98), in adjusted analyses. Only 33% (17 ...

Qualitative grading of mitral regurgitation severity has significant pitfalls secondary to hemodynamic variables, sonographic technique, blood pool entrainment, and the Coanda effect. Volumetric and proximal isovelocity surface area methods can be used to quantitate regurgitant orifice area, regurgitant volume, and regurgitant fraction, but have several limitations and can pose technical challenges. The vena contracta width method provides a rapid and accurate quantitative assessment of mitral regurgitation severity, but is clinically underused. This article is intended to generate an understanding of the flow mechanics of the vena contracta and the sonographic technique required to provide consistent and accurate measurements of vena contracta width in pati...

In this paper, we investigate a new solution for the energy efficiency (EE) maximization and power allocation problem in point-to-point multiple-input multiple-output (MIMO) spatial multiplexing schemes. Different from conventional energy-efficient optimization approaches that require iterative numerical algorithms, we derive an optimal solution in a closed form, which provides an insight upon the relation between the optimum EE and system parameters such as circuit power and channel conditions. In addition, using the proposed closed form function, we present an upper bound on the optimum EE in terms of the full active transmit antennas parameters. Based on the derived upper bound, we also propose a new antenna selection algorithm which achieves almost the s...

This paper presents the influence of natural surface ageing in indoor conditions on bonding quality of thermally modified wood used in structural laminated products. Two unmodified and thermally modified wood species were used for the experiment: oak and beech. Samples were planed and glued with MUF adhesive 2 hours, 1, 2, 6, 10, and 18 days after planing. Properties of laminated beech and oak beams, namely shear strength, delamination and contact angle, were measured in order to detect 1) suitability of wood species for lamination process and 2) influence of extended storage time after planing on properties of laminated wood. Generally, both native and thermally modified beech exhibited better results of shear strength and delamination and had lower contact...

Abstract Core-shell architectures have stimulated growing research interest because of their optimized physical/chemical properties and potential in many energy-related applications. In this work, a facile two-step hydrothermal-annealing method was adopted to synthesize hierarchical core-shell NiCo2O4@NiMoO4 nanoarrays on nickel foam substrate, and by controlling the growth time (2 h, 5 h and 8 h) of NiMoO4 precursor, three different morphologies and sizes of NiMoO4 nanosheets were obtained, and their morphology-dependent electrochemical performance was investigated. The results revealed that NiCo2O4@NiMoO4/NF (5 h) hybrid electrode exhibits a much enhanced specific capacitance of 2806 F g−1 at 5 A g−1, nearly three times than that of pristine si...

The adsorption capacity was examined of three different types of materials: a sludge which is mainly composed of calcium aluminum silicate and formed in water clarification and filtration and in dissolved air floatation units in petroleum refineries and thermal power stations, and garlic and onion peel as agricultural wastes. Results showed that the adsorption capacities of the chemically treated sludge with 30 μg/mL dodecyl benzene sulphonic acid, untreated sludge and the thermally treated sludge at 1200°C are 2, 1.388 and 0.8 g/g respectively, while, garlic and onion peels have adsorption capacities of 0.385 and 0.455 g/g respectively. These results were obtained by placing 0.6 g crude oil on a saline solution — 750 mL of 0.5 M NaCl at 30°C with diffe...

Focused on Nikolai Gogol’s absurdist tale, “The Nose” (1835), this article is an investigation into the concealed representation of suppressed and marginalized libertine and anti-religious discourses in nineteenth-century Russian literature. The author identifies overlooked idiomatic phraseology, forgotten specificities of the Imperial hierarchy (the Table of Ranks), and allusions to religious customs and Christian rituals that would have been apparent to Gogol’s readers and shows how some were camouflaged to escape censorship in successive drafts of the work. The research builds on the approaches to Gogol’s language, imagery and plot developed earlier by the Russian Formalists, Tartu-Moscow semioticians, and a few other scholars, who revealed the ...

Research question: To which extent do Disabled Supporter Associations (DSAs) contribute to improve access of fans with disabilities to football? This research question addresses two interrelated gaps: the lack of attention to supporters in European policies on inclusion in and through sport, and the excessive focus on physical barriers over other dimensions of access in both policy and research on disability and sport.Research methods: The study uses visual auto-ethnography. Seven disabled supporters, members of three different DSAs at football clubs in England, took part in the study. They were asked to take photographs of their life as a supporter over a period of eight weeks, and were interviewed at the end to discuss and clarify the meaning of the pictur...

The aim of this study was to examine whether phonemic decoding skill (deficits of which characterise dyslexia) shares genetic and/or environmental covariance with scholastic abilities independent of general intelligence. Non-word reading ability, verbal and non-verbal IQ, and standardised academic achievement (Queensland Core Skills Test; QCST) were measured in Australian twins (up to 876 twin pairs and 80 singleton twins). Multivariate genetic analysis showed the presence of a general genetic factor, likely reflecting crystallized ability, which accounted for 45-76% of phenotypic variance in QCST scores, 62% of variance in Verbal IQ, 23% of variance in Performance IQ, and 19% of variance in phonological reading ability. The phonemic decoding genetic factor ...

The sensor selection is a technique to reduce the cost, energy consumption, and complexity of a system by discarding redundant or less useful sensors. In this technique, one attempts to select a subset of sensors within a larger set so as to optimise a performance criterion. In this work, the authors consider the detection of sources in the 3D space when the source space could be sparsely represented. The application of compressive sensing (CS) methods in this setting has been extensively studied. Their aim in this work is to carry out the task of sensor selection in a planar array without sacrificing the detection performance. Their approach is to adopt the equivalent CS model and reduce the mutual coherence of the associated sensing matrix. This minimisati...

In this paper I investigate aspiration and glottal fricatives as found in languages with a phonological contrast. Using a global cross-linguistic sample, I establish a typology of aspiration outcomes in diachrony. The most important processes among these include transposition of glottal fricative, the less commonly encountered transposition of aspiration, spontaneous aspiration, and spontaneous loss of aspiration, together with the phenomenon of deaspiration. I set up certain parameters, which include laryngeal compatibility, directionality, and scope, in order to study the processes of the two transpositions and systematise them, while also attempting eventually to disentangle them from the way they are defined in some of the literature. Historical trajecto...

Cells need to organise and regulate their biochemical processes both in space and time in order to adapt to their surrounding environment. Spatial organisation of cellular components is facilitated by a complex network of membrane bound organelles. Both the membrane composition and the intra-organellar content of these organelles can be specifically and temporally controlled by imposing gates, much like bouncers controlling entry into night-clubs. In addition, a new level of compartmentalisation has recently emerged as a fundamental principle of cellular organisation, the formation of membrane-less organelles. Many of these structures are dynamic, rapidly condensing or dissolving and are therefore ideally suited to be involved in emergency cellular adaptatio...
