Functional enhancement of acute infracted heart by coinjection of autologous adipose-derived stem cells with matrigel

Recent clinical developments in tissue bioengineering have applications in acute cardiac ischemia and infarction and include the use of stem cells that combine injectable scaffold material. This study aimed to evaluate the effects of adipose-derived stem cells (ADSCs) that combine the Matrigel scaffold on cardiac morphology/functions. The autologous ADSCs myocardial infarction (MI) model was induced by the permanent ligation method of the left anterior descending coronary artery (LAD). MI-operated rats were randomly divided into PBS group, Matrigel group, PBS plus ADSCs group (PBS+ADSCs), and Matrigel plus ADSCs group (Matrigel+ADSCs). Matrigel was used as an injectable scaffold. Rats with a 1-week-old myocardial infarction were injected with 2 × 106 labeled ADSCs in the border area of the ischemic heart. Heart function was determined by echocardiography. The hemodynamics, cardiac structure, and graft characteristics were evaluated. The ADSCs were successfully isolated and identified, demonstrating a good proliferative status and cell retention in the Matrigel. ADSCs+Matrigel exhibited the most improved heart functions (LVESD, LVEDD, LVFS, LVEF) compared to those of other groups (p < 0.05). ADSCs+Matrigel significantly reduced infarct size compared to other groups (p < 0.05). Cotransplantation of ADSCs and Matrigel showed the best effect on maintaining the thickness of the ventricular wall compared to the other groups (p < 0.05). Engrafted ADSCs played a role in the formation of the neovasculature in myocardial infarction. ADSCs+Matrigel triggered the greatest enhancement in arteriole density than other groups (p < 0.05). Cotransplanting with ADSCs and Matrigel showed significantly higher levels of cardiac troponin T (cTnT), NK2-transcription factor related locus-5 (Nkx2.5), von Willebrand factor (vWF) than the other groups (p < 0.05). In conclusion, this study demonstrated that cotransplanting ADSCs with Matrigel resulted in improved cardiac morphology and cardiac function in the rat model of myocardial infarction.
Maternal Cigarette Smoking and Congenital Upper and Lower Limb Differences: A Systematic Review and Meta-Analysis

Maternal smoking during pregnancy has been associated with adverse effects on foetal development, including congenital limb anomalies. This systematic review aimed to provide an updated assessment of the association between maternal smoking during pregnancy and the risk of congenital limb anomalies. A systematic search was conducted to identify relevant studies published up to February 2023. Studies reporting on the relationship between maternal smoking during pregnancy and congenital digital anomalies or congenital limb reduction defects were included. Two independent reviewers screened the studies, extracted data, and assessed the quality of the included studies. Meta-analyses were performed to estimate the pooled odds ratios with 95% confidence intervals using fixed and random-effects models. In total, 37 publications comprising 11 cohort and 26 case-control studies were included in the systematic review. The meta-analysis demonstrated a significant increased risk of congenital limb reduction defects (pooled OR: 1.27, 95% CI: 1.18–1.38) in infants born to mothers who smoked during pregnancy. Similarly, a significant relationship was observed for the development of polydactyly/syndactyly/adactyly when considered as a single group (pooled OR: 1.32, 95% CI: 1.25–1.40). Yet, in contrast, no significant association was observed when polydactyly (pooled OR: 1.06, 95% CI: 0.88–1.27) or syndactyly (pooled OR: 0.91, 95% CI: 0.77–1.08) were considered individually. This systematic review provides updated evidence of a significant relationship between maternal smoking during pregnancy and increased risk of congenital limb anomalies. These findings highlight the potential detrimental effects of smoking on foetal limb development and underscore the importance of smoking cessation interventions for pregnant women to mitigate these risks.
Diagnosis of a short-pulse dielectric barrier discharge at atmospheric pressure in helium with hydrogen-methane admixtures

In this study, we present results from electrical, optical, and spectroscopic diagnosis of a short-pulse (250 ns) high-power impulse (up to 11 kW) dielectric barrier discharge at atmospheric pressure running in a helium/helium-hydrogen/helium-hydrogen-methane gas mixture. This plasma source is able to generate up to 20 cm3 of plasma volume, pulsed in kilohertz range. The plasma spatio-temporal dynamics are found to be developed in three distinct phases. All the experimental observations reveal a similar dynamic to medium power microsecond barrier discharges, although the power per pulse and current density are up to two orders of magnitude higher than the case of microsecond barrier discharges. This might open the possibility for new applications in the field of gas or surface processing, and even life science. These devices can be used in laboratory experiments relevant for molecular astrophysics.
Determination of Plasma Parameters in Radio Sources of Solar Zebra-patterns Based on Relations between the Zebra-stripe Frequencies and Gyro-harmonic Numbers

Solar radio zebras belong to the most important radio fine structures used in diagnostics of solar flare plasmas. In the present paper, assuming the double plasma-resonance model of zebras, we study the relation between zebra-stripe frequencies and gyro-harmonic numbers. We artificially generated two possible types of zebras: the zebra with Sequence A and Sequence B, where an increase of the zebra-stripe frequency corresponds to decrease or increase of the gyro-harmonic number. Analyzing these ideal zebras, we found that the frequency ratios of the neighboring zebra stripes increase in zebras with Sequence A and decrease in zebras with Sequence B. This criterion and corresponding diagrams were applied for nine observed zebras. All these zebras were found to be with Sequence A. Then we checked and confirmed these results by using the new numerical method, where the gyro-harmonic numbers of the zebra stripes with the lowest frequency s1 were also determined. We found that in all these zebras, the spatial scale of the magnetic field in the zebra-stripe sources was always shorter than that of the plasma density. Knowing the gyro-harmonic numbers and corresponding zebra-stripe frequencies, we determined the magnetic field and plasma density in zebra sources to be 0.84–37.31 G and 0.026 × 1010–16.03 × 1010 cm−3, respectively. Finally, we found that with increasing the gyro-harmonic number s1, the ratio of perpendicular and parallel scales of the magnetic field and plasma density in the zebra-stripe sources also increases.
The Dark Tetrad at Work

ABSTRACT The purpose of this study was to create and validate a short workplace-specific measure of the Dark Tetrad (i.e., narcissism, Machiavellianism, psychopathy, and sadism) that could be used by researchers, practitioners, and organizations. In Study 1, a two-wave longitudinal design (T1: N = 416; T2: N = 209) was used to develop and evaluate a 22-item scale that assessed the four dimensions. Each scale trait was positively associated with, and predicted, workplace deviance. The factor structure of the scale was replicated in a second sample (N = 289). These results have implications for developing new research on the Dark Tetrad in the workplace.
Phylogenetic Analysis of Klebsiella pneumoniae Isolated from Nosocomial and Community Infection in Diyala, Iraq

The biological diversity of Klebsiella pneumoniae (K. pneumoniae) has widely been reported to be associated with pathological progress in severe nosocomial and community-acquired infections. 250 clinical specimens included sputum, urine and swabs from wound and burns samples were collected from Al-Batool Teaching Hospital (38.4%), Baqubah Teaching Hospital (61.6%) and private laboratories in Baqubah and Diyala, Iraq. Positive rates of nosocomial acquired infection were sputum 98%, urine 96%, and swabs from wound and burns 94%, while positive rates of community acquired infection were sputum 60%, urine 60%, and swabs wound and burns 30%. Positive rates of nosocomial and community acquired infections were 96% and 48%, respectively. The distribution of pathogenic bacteria of E. coli was 19.2% and 8.8%, and those of K. pneumoniae were 23.2% and 12% of nosocomial and community acquired infections respectively, which is a higher percentage than other pathogenic bacteria of nosocomial and community acquired infections. The nosocomial-acquired K. pneumoniae isolates were less susceptible than community-acquired K. pneumoniae isolates. Multi-drug resistant (MDR) and extensively drug resistant (XDR) are commonly caused by -lactam/ -lactamase inhibitor combinations: Ticarcillin clavulanate, carbapenems and meropenem 100%; cephalosporines and ceftazidime 96%. Phylogenetic analysis of the 16S rRNA gene showed the presence of six nucleic acid variations in various samples. This variance might exhibit a clear tendency to be localized in the community acquired K. pneumoniae isolates. Fifteen ribosomal sequences were deposited at GenBank in accession numbers starts from OM992298 to OM992312.
Ownership Structure on Dividend Policy in The Indonesian Stock Exchange

Purpose: This research analyses how ownership structure affects dividend policy. Method: Quantitative with a pool least square (PLS) regression model was used as a research method, and the research sample was drawn from all non-financial sector companies registered in IDX from 2017 to 2021. Independent variables such as family ownership, institutional ownership, and concentration ownership. This research also has a control variable such as return on assets, debt to equity ratio, firm size, firm age, free cash flow, and volatility (business risk). Result: This research found that family ownership, institutional ownership, concentration ownership, return on assets, firm size, age of firm, free cash flow, and volatility (business risk) all have a significant effect on dividend yield, but the debt to equity ratio has no effect.
Some classes of integral transforms on distribution spaces and generalized asymptotics

In this doctoral dissertation several integral transforms are discussed.The first one is the Short time Fourier transform (STFT). We present continuity theorems for the STFT and its adjoint on the test function space K1(ℝn) and the topological tensor product K1(ℝn) ⊗ U(ℂn), where U(ℂn) is the space of entirerapidly decreasing functions in any horizontal band of ℂn. We then use such continuity results to develop a framework for the STFT on K'1(ℝn). Also, we devote one section to the characterization of K’1(ℝn) and related spaces via modulation spaces. We also obtain various Tauberian theorems for the short-time Fourier transform. Part of the thesis is dedicated to the ridgelet and the Radon transform. We define and study the ridgelet transform of (Lizorkin) distributions and we show that the ridgelet transform and the ridgelet synthesis operator can be extended as continuous mappings Rψ : S’0(ℝn) → S’(Yn+1) and Rtψ: S’(Yn+1) → S’0(ℝn). We then use our results to develop a distributional framework for the ridgelet transform that is, we treat the ridgelet transform on S’0(ℝn) via a duality approach. Then, the continuity theorems for the ridgelet transform are applied to discuss the continuity of the Radon transform on these spaces and their duals. Finally, we deal with some Abelian and Tauberian theorems relating the quasiasymptotic behavior of distributions with the quasiasymptotics of the its Radon and ridgelet transform. The last chapter is dedicated to the MRA of M-exponential distributions. We study the convergence of multiresolution expansions in various test function and distribution spaces and we discuss the pointwise convergence of multiresolution expansions to the distributional point values of a distribution. We also provide a characterization of the quasiasymptotic behavior in terms of multiresolution expansions and give an MRA sufficient condition for the existence of α-density points of positive measures.
Pricing options on investment project expansions under commodity price uncertainty

In this work we develop PDE-based mathematical models for valuing real options on investment project expansions when the underlying commodity price follows a geometric Brownian motion. The models developed are of a similar form as the Black-Scholes model for pricing conventional European call options. However, unlike the Black-Scholes' model, the payoff conditions of the current models are determined by a PDE system. An upwind finite difference scheme is used for solving the models. Numerical experiments have been performed using two examples of pricing project expansion options in the mining industry to demonstrate that our models are able to produce financially meaningful numerical results for the two non-trivial test problems.
Operationalizing racialized exposures in historical research on anti-Asian racism and health: a comparison of two methods

Background Addressing contemporary anti-Asian racism and its impacts on health requires understanding its historical roots, including discriminatory restrictions on immigration, citizenship, and land ownership. Archival secondary data such as historical census records provide opportunities to quantitatively analyze structural dynamics that affect the health of Asian immigrants and Asian Americans. Census data overcome weaknesses of other data sources, such as small sample size and aggregation of Asian subgroups. This article explores the strengths and limitations of early twentieth-century census data for understanding Asian Americans and structural racism. Methods We used California census data from three decennial census spanning 1920–1940 to compare two criteria for identifying Asian Americans: census racial categories and Asian surname lists (Chinese, Indian, Japanese, Korean, and Filipino) that have been validated in contemporary population data. This paper examines the sensitivity and specificity of surname classification compared to census-designated “color or race” at the population level. Results Surname criteria were found to be highly specific, with each of the five surname lists having a specificity of over 99% for all three census years. The Chinese surname list had the highest sensitivity (ranging from 0.60–0.67 across census years), followed by the Indian (0.54–0.61) and Japanese (0.51–0.62) surname lists. Sensitivity was much lower for Korean (0.40–0.45) and Filipino (0.10–0.21) surnames. With the exception of Indian surnames, the sensitivity values of surname criteria were lower for the 1920–1940 census data than those reported for the 1990 census. The extent of the difference in sensitivity and trends across census years vary by subgroup. Discussion Surname criteria may have lower sensitivity in detecting Asian subgroups in historical data as opposed to contemporary data as enumeration procedures for Asians have changed across time. We examine how the conflation of race, ethnicity, and nationality in the census could contribute to low sensitivity of surname classification compared to census-designated “color or race. ” These results can guide decisions when operationalizing race in the context of specific research questions, thus promoting historical quantitative study of Asian American experiences. Furthermore, these results stress the need to situate measures of race and racism in their specific historical context.
Efficient Semi-Lagrangian Vlasov-Maxwell Simulations of High Order Harmonic Generation from Relativistic Laser-Plasma Interactions

We describe a relativistic semi-Lagrangian scheme for the numerical solution of the relativistic Vlasov-Maxwell system. The implementation strategy on a modern non-unified memory access (NUMA) architecture using the OpenMP framework is discussed. We demonstrated that close to perfect scaling can be obtained on modern many-core, multi-socket systems. Application of this code to the problem of relativistic generation of high-harmonic laser radiation is demonstrated. The results are compared to particle-in-cell (PIC) simulations, indicating in particular that for warm plasma the Vlasov simulation is superior. We discuss the impact of plasma temperature on the radiation spectrum and show that the efficiency of harmonic generation depends on the plasma temperature.
A Rhetorical Structural Analysis of Introductions in L2 Saudi Students’ Argumentative Essays

The introduction is a pivotal sub-genre in academic writing because of its rhetorical role in determining whether a written work is necessary and worth reading. A significant body of research has examined the rhetorical structure of introductions in different written text genres, such as research articles and dissertations. However, little research has investigated the rhetorical moves of the introduction in undergraduate students’ academic essays, particularly in the Saudi context. Therefore, this study aimed to explore the rhetorical moves in the introductions of argument essays. Also, the rhetorical strategies (steps) employed to construct each move in the introduction did not receive much attention. Hence, the second purpose of this study is to explore how each move in the introduction was rhetorically constructed. This study analyzed 49 introductions from argument essays written by L2 undergraduate Saudi students at a Saudi university. The textual data was analyzed according to Hyland’s (1990) five moves in the introduction section of his proposed model. The results showed that most students employed Move 1, Move 2, and Move 3 to compose their introductions. It was also found that while Move 4 was not used in several introductions, Move 5 was excluded from all the texts. The study also determined lists of steps to construct Move 1 and Move 2, whereas Move 3 was mostly constructed with the thesis statement (Step 2). The findings of this study have pedagogical and research implications for L2 students’ academic writing. Received: 10 May 2023 / Accepted: 15 June 2023 / Published: 5 July 2023
OVERVIEW OF MEDICATION ERROR INCIDENCE IN HOSPITALS IN VARIOUS COUNTRIES: LITERATURE REVIEW

Background: Medication error is one of the most common types of errors contributing to patient safety incidents in hospitals. In addition to their numerous cases and high costs, medication errors also contribute to deaths in various countries. Aims: This study describes the incidence of medication errors in hospitals in various countries, determines the phase of errors that occurred the most, and describes preventive strategies for medication errors in hospitals. Methods: This study was conducted between April 2021-July 2021 using the literature review method. Data were retrieved from ProQuest, ScienceDirect, PubMed, Google Scholar, and Garuda RistekBRIN. The data are generalized and extracted in a table based on the incidence of medication errors and preventive strategies. Results: Of the eleven included studies, the incidence of medication errors in one study conducted in Nigeria was the highest (80%). Four of the eleven studies were conducted in India with varying incidence rates. Most errors occurred during the prescribing stage. The number of reports and the number of events actually have no relevance. It can be said that countries with a high number of reporting have good reporting indicators. Strategies for preventing medication errors include the implementation of an information system in the CPOE (Computerized Physician Order Entry) form and providing training for staff. Conclusion: The difference in the incidence of medication errors in developing and developed economies can be attributed to factors in the healthcare system and the lower prescribing ratio and nurse ratio in developing countries. Keywords: literature review, medication errors, patient safety
Associated vector boson production with b-jets at LHCb and Beam-Gas Vertexing at LHC for beam instrumentation

Associated vector boson production with b-jets at LHCb and Beam-Gas Vertexing at LHC for beam instrumentation Valdir Salustino Guimarães Orientador: Murilo Santana Rangel Abstract da Tese de Doutorado apresentada ao Programa de Pós-Graduação em F́ısica do Instituto de F́ısica da Universidade Federal do Rio de Janeiro UFRJ, como parte dos requisitos necessários à obtenção do t́ıtulo de Doutor em Ciências (F́ısica). da Tese de Doutorado apresentada ao Programa de Pós-Graduação em F́ısica do Instituto de F́ısica da Universidade Federal do Rio de Janeiro UFRJ, como parte dos requisitos necessários à obtenção do t́ıtulo de Doutor em Ciências (F́ısica). This thesis presents the cross-section measurements of associated vector bosons production with bottom quarks jets at 7 and 8 TeV of centre-of-mass energies. The first channel for cross-section measurement is the Z+b-jet with Z/γ∗→ μ+μ− in proton-proton collisions at √ s = 7 TeV using data collected by the LHCb experiment in 2011. The second channel is the W + bb, requiring two b-jets and one lepton. Apart from cross-section measurement this channel is also used to calculate limits of the Higgs boson produced in association with a vector boson and decaying into a pair of bottom or charm quarks. One of the main source of systematic errors in these analyses is the jet energy resolution and correction. Reduction of this error is achieved by performing a calibration of the neutral jet energy component, named neutral recovery, where empirical functions of the ratio between the charged particle energy of the jet and the particle momentum are determined. This method improves the jet energy resolution.
