Abstract

Inspired by the growing interest in linking several behaviors with specific genetic assets, research on the topic spiked in recent years, showing that several genetic variants of dopaminergic and serotonergic pathways are related to both emotional and cognitive components of social decision-making. In this paper, we explored the relationship between dopaminergic and serotonergic allelic variants and both behaviors and beliefs about others’ behaviors in an online the Public Goods Game with and without punishment. We found that: (i) the T/T genotype of 5-HTR1B-rs13212041 was associated with an expectation of less antisocial and spiteful punishment; (ii) the L/L genotype of 5-HTTLPR was related to smaller contributions to the public good in the absence of the punishment option and (iii) with expectations of smaller contributions by others in the same setup; (iv) the A/A (Met/Met) genotype of COMT-rs4680 (Val158Met) was associated with expectations of smaller contributions in the presence of punishment. Overall, these results indicate that specific dopaminergic and serotonergic gene variants affect both actions and expectations about others’ behavior in social contexts.

Abstract

Background There is a considerable evidence in the literature highlighting the impact of psychological factors on the development of coronary heart disease. In India, there's a rising incidence of traumatic life events alongside coronary heart disease, yet the connection between them remains relatively understudied. Therefore, this study aims to investigate the occurrence of stressful life events among patients experiencing their first episode of acute coronary syndrome (ACS) and to compare this with controls.Results The mean number of stressful life events (SLEs) observed was 5.07 ± 2.04 in cases and 4.35 ± 1.88 in controls, with a p-value of < 0.05. The median number of SLEs in cases was nine, compared to eight in controls. Additionally, cases experienced a higher number of SLEs compared to controls with adjusted Z scores of 2.01 for 9 events, 2.74 for 8 events and 3.46 for five events with p-value < 0.01 for all. Significant differences for various types of SLEs were observed between cases and controls.Conclusion The number for SLEs was significantly higher in cases than in controls. There is a need for further research to ascertain and quantify the role of stressful events and risk of a cardiac event.

Published: September 2024

Abstract

Medical images often require segmenting into different regions in the first analysis stage. Relevant features are selected to differentiate various regions from each other, and the images are segmented into meaningful (anatomically significant) regions based on these features. The purpose of this study is to present a model for segmenting and identifying the local tumor formation in MR images of the human brain. The proposed system operates in an unsupervised manner to minimize the intervention of expert users and to achieve an acceptable speed in the tumor classification process. The proposed method includes several steps of preprocessing for different brain image classify that Perform the normalization task. These preprocessing steps lead to more accurate results in high-resolution images and ultimately improve the accuracy and sensitivity of tumor separation from brain tissue. The output of this stage is applied to a self-encoding neural network for image zoning. By nature of self-encoding networks, leads to reduce the dimensionality of tumor pixels from the surrounding healthy environment, which significantly helps remove regions incorrectly extracted as tumors. Finally, by extracting features from the previous stage's output through Otsu thresholding, the surrounding area and type of tumor are also extracted. The proposed method was trained and tested using the BRATS2020 database and evaluated by various performance metrics. The results based on the Dice Similarity Coefficient (DSC) show an accuracy of 97% for the entire MR image and improved detection accuracy compared to other methods, as well as a reduction in the cost of the diagnostic process.

Published: September 2024

Abstract

Cytochrome P450 1A2 (CYP1A2) is known to be the main enzyme directly responsible for caffeine metabolism. The rs762551 (NC_000015.10:g.74749576C > A) is a single nucleotide polymorphism characterized by higher enzyme activity in the presence of an inducer such as heavy coffee consumption and its protective role against developing cardiovascular diseases, including high blood pressure. In this comprehensive study, we aim to evaluate any association between coffee intake, CYP1A2 polymorphism, the presence of high blood pressure, and their potential role in cardiovascular outcomes. For 355 individuals, a PCR technique was performed using TaqMan SNP genotyping Assay, analyzing rs762551 on LightCycler 480 (Roche) with Gene Scanning software version 1.5.1 (Roche). Using binomial logistic regression, we found that the individuals who consumed more than three cups of coffee per day are less likely to fit in the slow coffee metabolizers category with an odds ratio of 0.386 and p = 0.033. Another important finding would be the fact that the fast coffee metabolizers (AA genotype) consume larger coffee quantities, although they present the lowest tensional values and the highest values for cholesterol and glucose. When approaching the hypertensive subjects, they show lower coffee consumption and lower caffeine levels, compared to the control group. The main conclusion of this study would be that only coffee intake and genotype are statistically related, although no statistically significant associations regarding the high blood pressure have been found.

Abstract

The production of nitrogen oxides (NOx = NO + NO2) is substantial in urban areas and from fossil fuel-fired power plants, causing both local and regional pollution and presenting severe consequences for human health. To estimate their emissions and implement air-quality policies, authorities often rely on reported emission inventories. The island of Cyprus is de facto divided into two different political entities, and as a result, emissions inventories are not systematically available for the whole island. We map NOx emissions in Cyprus for two six-month periods in 2021 and 2022 with a flux-divergence scheme, using spaceborne retrievals of nitrogen dioxide (NO2) columns at high spatial resolution from the TROPOMI instrument, as well as horizontal wind data to derive advection and concentrations of OH, NO and NO2 to derive chemical processes. Emissions are estimated under three different settings using ECMWF data and WRF-Chem simulations. These settings are chosen for their differences in spatial resolution and representation of wind and air composition. Exploiting the low emissions in Cyprus, we show that the flux-divergence method is limited by the resolution of wind and hydroxyl radical, the signal-to-noise ratio of the observed tropospheric column densities, and the NOx:NO2 ratio above the main pollution sources. We also provide an estimation of NOx emissions for the five power plants of the island. The estimated emissions for the three power plants in the south are in the range of reported emissions and global/regional inventories, and present differences in seasonal cycles. For the two power plants in the north, which are not included in all emission inventories, we estimate mean daytime emissions higher than for the power plants in the south combined, despite a much lower production capacity, illustrating the application of different environmental norms and the use of different technologies and fuels in the two parts of Cyprus.

Published: September 2024

Abstract

Objective
The impact of endoscopic transsphenoidal pituitary surgery (ETSs) on endocrine function is a critical concern of surgical treatment of pituitary tumors. This study evaluated post-ETSs pituitary disease control (DC), development of early and late new hormonal deficiencies, and recovery of pre-existing hormonal deficiency. Additionally, studied the preoperative factors that influence post-ETSs outcome.
Methods
A prospective cohort study conducted in neuroendocrine field in Erbil city from April 2023 to April 2024. The study included 35 patients who were assigned for ETSs after exclusion of those with prior neurosurgical intervention, radiation, or drugs affecting pituitary function. Initial clinical evaluation, endocrine tests and radiological imaging performed pre-ETSs, then at early postoperative period and later follow up scheduled at one-, three-, and six-month interval.
Results
Post-ETSs, DC achieved in 20 (57.1%) of patients. At six-month follow up, about 10/18 (55.5%) patients recovered at least one hormone postoperatively with gonadal axis was the most frequent 5 (14.3%), while new hormonal deficiencies documented in 12 (34.3%) patients, among which prolonged Diabetes insipidus (DI) was the most frequently encountered 11 (31.4%). Early post-ETSs water dysregulation significantly prolonged hospital stay (p-value 0.035). Tumor size, knops classification and surgeon experience were the main variables associated with endocrine outcome.
Conclusion
In Iraq, Erbil city, DC rate was lower than previous studies, and development of new hormonal deficiencies was higher and contributed to prolonged DI. However, a considerable number of patients had recovery of pre-existing hormonal deficiencies compared to prior studies. These findings necessitate revision of our surgical management.

Published: September 2024

Abstract

The methodology of image fusion combines correlative information from several images into a single image which facilitates better visual perception and higher accuracy for further processing task than each of the target images. This fusion process is computationally expensive for large scale images. A parallel fusion scheme leads to Neutron radiography (NR) as well as X-ray radiography (XR) incorporating the Newton bucketing method along with depreciation effective on total variation scheme of anisotropic diffusion of 2nd order devised on Multi-core CPU-GPU based CUDA compatible platform, presented here. This scheme is unique and stable in terms of Euler-Lagrange solutions of the second-order anisotropic diffusion. Discretization method based on finite difference is used to establish precise and efficient numerical approximation whereas dependency of parameters also demonstrated in our proposed model. This scheme generates a sharp and enhanced fused image that combined smooth information of the NR and details of XR image simultaneously without noise and blur artifacts of the source images. In order to perform an efficient parallel fusion, all kernel functions have been implemented on GPU in this proposed scheme. This CPU-GPU based model makes a major difference on the basis of performance acceleration related to other sequential schemes devised on CPU. Experimental results exhibit performance acceleration and provide superior fusion outcomes than available approaches with regard to both quantitative and optical perceptivity.

Abstract

Litchi is an important economic crop with a wide planting area and large yield worldwide. To explore the solid wood utilization value of litchi, this work systematically tested the physical and chemical properties of litchi wood, summarized the drying characteristics using the 100℃-Test Method, and formulated the drying schedule of litchi wood to evaluate the drying quality. The results showed that the drying time of litchi wood from an initial moisture content of 41.38–11.28% was 435 hours, and the drying rate was 0.069%/h. According to GB/T 6491 − 2012 "Sawn Timber Drying Quality Standard," the comprehensive quality grade of litchi wood was grade 2. Dried sawn timber can meet the quality requirements of solid wood furniture and handicrafts. In addition, the porous structure of litchi wood mainly consisted of micro and medium pores, with a porosity of 31.93% and an average pore size of 23.07 nm. The small pore cavities on the cell wall resulted in difficult water transfer, leading to a slow drying speed. However, the porous structure of litchi wood has a positive effect on dimensional stability.In addition, the shrinkage grade of litchi wood was medium, comparable to white oak, ash, and rubber wood under the same environmental conditions. Moreover, the linear and volumetric swelling rates of litchi wood were only higher than rubber wood but lower than white oak. Litchi wood exhibited a larger hygroscopic hysteresis, significantly higher than that of control wood, indicating better dimensional stability. In conclusion, litchi wood is an excellent renewable biological resource and has excellent drying, processing, physical, and mechanical properties, making it a potential candidate for solid wood utilization.

Authors: Dahman Deniz 
Published: September 2024

Abstract

Data holds a crucial role in the standard system of input, processing, and output, particularly representing the input. With high-quality data, there is an assurance of a smooth process and an effective outcome. However, the issue of privacy in data acquisition has become a significant concern in recent years, forming the core of numerous research studies. This paper introduces a novel approach to generating synthetic data that retains the same statistical structure as the original, based on the geometrical representation of each data point. This newly generated synthetic data can act as a substitute for the original, ensuring the integration of privacy into any application utilizing the data. Experimental results on two datasets of varying sizes demonstrate that the proposed method can effectively produce synthetic data with the same statistical structure and a comparable level of accuracy for predictive tasks as the original data.

Abstract

Phosphogypsum (PG) is considered a by-product, characterized as solid waste that occurs for manufacturing phosphoric acid by reacting of the sulfuric acid with the phosphate rock according to the wet method. Heavy metals in PG cause a series of drawbacks and negative impacts for global environment and create various restrictions in PG applications. In this article, the Box-Behnken Design (BBD) technique was chosen for the simultaneous decrease of lead, nickel, manganese and chromium heavy metals from PG with Na2EDTA which lead to optimizing factors such as Na2EDTA concentration, liquid to solid (L/S) ratio and contact time and creating a mathematical model. The optimal process points were identified using the analysis of variance (ANOVA) and the surface response plots. Moreover, the physicochemical properties, before and after purification of PG were studied by XRF, XRD and FTIR methods. Regarding the results found by applying the response surface design methodology, the coefficients of correlation (R2) of the experimental data and the second-order regression model for Pb, Ni, Mn and Cr were determined as 89.75%, 95.37%, 98.18% and 94.53%, respectively. Generally, high R-squared values ​​state that the experimental data are compatible that the data predicted by the model Under optimum conditions, Na2EDTA concentration: 0.055 M, liquid/solid ratio: 20:1 ml/g, contact time: 157 minutes and the removal of lead, nickel, manganese and chromium were 46.65%, 42.31%, 67.02% and 77.9% respectively.

Published: September 2024

Abstract

The cloud manufacturing model plays a crucial role in the deep integration of information technology and the manufacturing industry, which dynamically adjusts manufacturing processes. If the optimization of collaborative manufacturing resources does not fully consider the intrinsic relationship among tasks, service resources, and dynamic constraints, there will be a significant deviation between the anticipated production process and the reality. To overcome these shortcomings, this paper constructs a Pareto optimal service selection model with multiple production constraints suitable for a cloud manufacturing environment. The Pareto dominance strategy is applied to filter out non-candidate solutions, subsequently, the tournament selection strategy is employed to select services from the Pareto archive set based on their fitness values, which enhances the diversity of solutions and improves multi-target search capabilities. Application examples confirm that the proposed algorithm outperforms other comparison algorithms in performance.

Abstract

Background: This study aimed to assess the seroprevalence of SARS-CoV-2 among children attending pediatric consultations in Bamako, Mali, using a rapid diagnostic test (RDT) on fingertip or venous blood samples.
Methods: A single-center, prospective cross-sectional study was conducted from May to September 2022 at the Pediatric Hospital in Bamako, Mali. Children aged 1 to 15 years underwent phlebotomy or fingertip blood sampling for SARS-CoV-2 antibody testing using the Abbott Panbio COVID-19 IgG/IgM Test. Demographic data and potential risk factors were collected. Categorical variables were compared using Fisher's exact test, and quantitative variables were analyzed using the Mann-Whitney test.
Results: A total of 315 children were included, with a median age of 6 years (range 3-9 years); 45.7% (144/315) were younger than 6 years, and 54% (170/315) were male. The majority lived in urban areas (89.9%) and used public transportation (85.7%). The overall seroprevalence was 63.5%, with a higher seroprevalence observed among children aged 6 years and older compared to those under 6 years. The odds of having a positive serology were approximately twice as high in children aged ≥6 years in both univariate (OR 1.99; 95% CI: 1.25-3.17; P=0.0014) and multivariable analyses (OR 2.05; 95% CI: 1.26-3.32; P=0.0038). No significant differences in seropositivity were found for other demographic or risk factors.
Conclusions: A substantial proportion of children in Bamako showed evidence of past SARS-CoV-2 infection, underscoring the importance of continued surveillance and preventive measures in this population.
