Published: February 2024

Abstract
In this study, a plane strain finite element analysis (FEA) was employed to investigate failure mechanisms of a hydrogen storage pipe system made of 316L stainless steel pipe coated with pure and functionally graded (FG) ceramic layers composed of Al2O3 and SiC. The system was studied for different common failure mechanisms, i.e., delamination, surface cracking and buckling delamination, upon cooling from an elevated stress-free temperature. Finally, the composition and thickness of the coating layers were considered as the main controlling factors and investigated for their influence on the studied failure mechanisms. It was observed that the most energetically favourable cracking mechanism for this type of system was surface cracking with the propagation of these cracks eventually leading to different failure paths. Buckling was found to be as less energetically favourable compared to surface cracking with the buckling resistance being enhanced by changing the coating thickness and composition factor.

Abstract

Objective: Postoperative pulmonary complications (PPCs) are the most frequent complications after esophagectomy, which usually causes to hypoxemia. The aim of this study is to evaluate whether regional anesthesia combined with awake delayed extubation improves postoperative oxygenation index after esophagectomy.
Methods: Ninety patients diagnosed with esophageal cancer undergoing elective thoracolaparoscopic esophagectomy were randomized to three groups, control group (C group), regional anesthesia group (N group) and regional anesthesia combined with awake delayed extubation group (ND group). Regional anesthesia included serratus anterior plane block, transversus abdominis plane block, and rectus abdominis sheath block. Awake delayed extubation was defined as removing the endotracheal tube 30 min after waking up. The primary outcome was postoperative oxygenation index; secondary outcomes were the incidence of PPCs, analgesics consumption, postoperative pain scores, time to first flatus, time to first defecation, and hospital stays.
Results: The oxygenation index of ND group was significantly higher than the N group（P＜0.05) and C group（P<0.05) at 1 hour and 24 hours postoperatively. The incidence of PPCs was significantly lower in the ND group than in the N group and C group (61.5% vs.51.8% vs. 25.9%, p = 0.026*).
Conclusion: Regional anesthesia combined with awake delayed extubation can significantly improve postoperative oxygenation index, reduce the incidence of PPCs, and promote patient recovery after thoracolaparoscopic esophageal cancer surgery.
Trial registration: The study was registered on Chinese Clinical Trial Registry, (ChiCTR2200066726) on 12/05/2023.

Abstract

Background Immediate initiation of contraception after childbirth can have positive effects on women and their families by helping them to effectively plan the spacing of births. Research indicates that women often desire the presence of their male partners during childbirth to actively engage in the initiation of contraceptive use. The involvement of men in this process is of utmost importance. Nevertheless, there is a scarcity of evidence that explores the impact of male partners' physical presence during childbirth on the initiation of immediate postpartum family planning by couples. Methods A quantitative cross-sectional study was carried out in two hospitals located in Kigali. Prior to their discharge, a questionnaire was administered by an interviewer to 480 women in order to gather data on various aspects including demographic information, the presence of partners during childbirth, and the selection of family planning methods. To analyze the collected data, descriptive statistics and inferential analytical methods were employed to determine frequencies, percentages, and associations between different variables. Results Out of the 480 women who participated in the study, a total of 232 women, accounting for 48.3%, reported that their male partners were present during childbirth. Additionally, 60.6% of the women opted for a family planning method immediately after giving birth, with 33.7% of them choosing intrauterine devices. When it comes to the decision-making process, 42% of the 291 women who selected a preferred method made the decision on their own, while 34% made a joint decision with their partners. Among the 189 women who did not choose any family planning method, 27% stated that it was too early for them to make a decision, and 25.9% mentioned that they needed time to recover first. Interestingly, although a slightly higher proportion of women (63.4%) whose partners were present at birth initiated immediate postpartum contraceptive use compared to women whose partners were not present (58.1%), there was no significant statistical difference between the two groups (χ2 = 1.409, P = 0.137). Conclusion The current data suggests that the presence of male partners during childbirth is still relatively low and requires additional efforts to improve. In order to increase men's participation in decision-making regarding immediate postpartum family planning, healthcare facilities should focus on enhancing family planning education. Furthermore, conducting a comprehensive study on a larger scale would be beneficial to explore the impact of male partners' presence on couples' initiation of family planning immediately after childbirth.

Authors: Wang Jingze , Liu Siyu 
Published: February 2024

Abstract
Background: Medical information plays an important role in doctor-patient communication.
Objective: This study were conducted to explore how the types of medical information and the information risk symmetry affect patients' medical satisfaction in different types of doctor-patient communication (doctor-center/patient-center).
Method: This is a experiment study.
Results: The results showed that: (1) Regardless of the types of doctor-patient communication, higher medical satisfaction tend to appear when patients receive more treatment information than disease information. (2) The medical satisfaction of doctor-centered communication was significantly higher than that of patient-centered communication when presented with asymmetric risk medial information.
Conclusions: Delivering more treatment information is beneficial to improving treatment outcomes. Meanwhile, doctors should be trained to correctly deliver medical information.

Abstract

In the past decade, next-generation sequencing (NGS) has revolutionized genetic diagnostics for rare neurological disorders (RND). However, the lack of standardized technical, interpretative, and reporting standards poses a challenge for ensuring consistent and high-quality diagnostics globally. To address this, the European Reference Network for Rare Neurological Diseases (ERN-RND) collaborated with the European Molecular Genetics Quality Network (EMQN) to establish an external quality assessment scheme for NGS-based diagnostics in RNDs. The scheme, initiated in 2021 with a pilot involving 29 labs and followed by a second round in 2022 with 42 labs, aimed to evaluate the performance of laboratories in genetic testing for RNDs. Each participating lab analysed genetic data from three hypothetical cases, assessing genotyping, interpretation, and clerical accuracy. Despite a majority of labs using exome or genome sequencing, there was considerable variability in gene content, sequencing quality, adherence to standards, and clinical guidance provision. Results showed that while most labs provided correct molecular diagnoses, there was significant variability in reporting technical quality, adherence to interpretation standards, reporting strategies, and clinical commentary. Notably, some labs returned results with the potential for adverse medical outcomes. This underscores the need for further harmonization, guideline development, and external quality assessment in the evolving landscape of genomic diagnostics for RNDs. Overall, the experience with the scheme highlighted the generally good quality of participating labs but emphasized the imperative for ongoing improvement in data analysis, interpretation, and reporting to enhance patient safety.
Acoustics for seismic monitoring H2 storage in saline aquifers. A comparative study with the CO2 and CH4 cases.
Authors: Gei Davide , Carcione Jose Maria , Picotti Stefano 
Published: February 2024

Abstract
We model the acoustics of rocks partially saturated with hydrogen. We compare the acoustic properties of H2 (hydrogen), CO2 (carbon dioxide) and CH4 (methane) and those of rocks saturated with these gases and brine. The gas properties are obtained from the Peng-Robinson equation of state, and we consider the pressure-temperature conditions based on a linear basin modeling with a constant geothermal gradient. The bulk and shear moduli of the dry rock are obtained with the Krief model, while the Athy equation is used to calculate the porosity as a function of depth. Mesoscopic attenuation and velocity dispersion due to fluid effects is quantified using the Johnson model. The viscoelastic Cole-Cole model is used to describe the velocities and attenuation predicted by the Johnson model when synthetic seismograms with an equivalent viscoelastic rheology are to be calculated. In this case, the P-wave velocity as a function of gas saturation is obtained with the Gassmann equation and an effective fluid modulus based on the Brie equation.
Micro seepage of hydrocarbon gas and its significance for oil-gas exploration in the Northern South China Sea
Authors: Kangshou Zhang , Guangjian Zhong 
Published: February 2024

Abstract
Submarine hydrocarbon gas seepage is a widespread natural phenomenon, resulting in hydrocarbon anomalies of shallow surface sediment. Seepage includes macro seepage and micro seepage, a large number of macro seepage studies have investigated in South China Sea, relatively little is known about micro seepage, and very few studies of micro seepage in oil-gas exploration have been carried out. Chaoshan Depression is a Mesozoic and Cenozoic superimposed depression in the northern South China Sea, it has good potential for oil-gas exploration, but oil and gas have not been discovered through drilling. Effective identification and prediction of favorable exploration areas and reservoirs are the key to successful exploration. Gas chromatography-mass spectrometry is used for qualitative and quantitative analysis of the abundance and structural anomalies of light and heavy hydrocarbons, and Kriging method is used to determine the areal distribution characteristics of light and heavy hydrocarbons and the carbon isotope values δ13C (‰) of methane. As a result, two comprehensive abnormal zones for oil-gas exploration were delineated in the northeast and southwest parts of the Chaoshan Depression, respectively. By analyzing the differentiation and fabric characteristics of hydrocarbon gases, as well as methane δ13C (‰), the underlying petroleum reservoirs are identified as gas reservoirs, and the seismic imaged DS-A structure is predicted to be a gas-rich structure. By correlating the seismic data and geochemical anomalies, it is clarified that micro-fractures are the main controlling factors for the occurrence of the seabed geochemical anomalies, and a composite formation mechanism of “lower generation, upper accumulation and micro fractures leaking” has been proposed.

Abstract

Schizophrenia spectrum disorders (SCZspect) are associated with altered function in the auditory cortex (AC), indicated by reduced N100 amplitude of the auditory evoked potential (AEP). While the neural substrate behind reduced N100 amplitude remains elusive, myelination in the AC may play a role. We compared N100 amplitude and magnetic resonance imaging (MRI) T1 weighted and T2 weighted ratio (T1w/T2w-ratio) as a proxy of myelination, in the primary AC (AC1) and secondary AC (AC2) between SCZspect (n = 33, 48% women) and healthy controls (HC, n = 144, 49% women). Further, we examined associations between N100 amplitude and T1w/T2w-ratios in SCZspect and HC. We finally explored N100 amplitude and T1w/T2w-ratios in the AC1/AC2 and association between N100 amplitude and T1w/T2w-ratios between male and female SCZspect and HC. N100 amplitude did not differ between SCZspect and HC or between female SCZspect and female HC, but was significantly reduced in male SCZspect compared to male HC (est = 4.3, se = 1.63, t = 2.63, p = 0.010). Further, T1w/T2w ratios in the AC1/AC2 did not differ between any groups. Finally, N100 amplitude was not associated with T1/T2-ratios in the AC1/AC2 in any groups. Reduced N100 amplitude in male SCZspect compared to male HC, suggest that sex-specific effects should be considered in research on SCZspect neurophysiology. Our findings did not support the hypothesis that reduced myelination in the AC1/AC2, as indexed by T1w/T2w-ratio, underlies N100 abnormalities in SCZspect. However, more precise estimates of intracortical myelin are needed to confirm this.

Abstract
Gibel carp (Carassius gibelio) is a cyprinid fish that originated in eastern Eurasia and is considered as invasive in European freshwater ecosystems. The populations of gibel carp in Europe are mostly composed of asexually reproducing triploid females (i.e., reproducing by gynogenesis) and sexually reproducing diploid females and males. Although some cases of coexisting sexual and asexual reproductive forms are known in vertebrates, the molecular mechanisms maintaining such coexistence are still in question. Both reproduction modes are supposed to exhibit evolutionary and ecological advantages and disadvantages. To better understand the coexistence of these two reproduction strategies, we performed transcriptome profile analysis of gonad tissues (ovaries) and studied the differentially expressed reproduction-associated genes in sexual and asexual females. We used high-throughput RNA sequencing to generate transcriptomic profiles of gonadal tissues of triploid asexual females and males, diploid sexual males and females of gibel carp, as well as diploid individuals from two closely-related species, C. auratus and Cyprinus carpio. Using SNP clustering, we showed the close similarity of C. gibelio and C. auratus with a basal position of C. carpio to both Carassius species. Using transcriptome profile analyses, we showed that many genes and pathways are involved in both gynogenetic and sexual reproduction in C. gibelio; however, we also found that 1500 genes, including 100 genes involved in cell cycle control, meiosis, oogenesis, embryogenesis, fertilization, steroid hormone signaling, and biosynthesis were differently expressed in the ovaries of asexual and sexual females. We suggest that the overall downregulation of reproduction-associated pathways in asexual females, and their maintenance in sexual ones, allow for their stable coexistence, integrating the evolutionary and ecological advantages and disadvantages of the two reproductive forms. However, we showed that many sexual-reproduction-related genes are maintained and expressed in asexual females, suggesting that gynogenetic gibel carp retains the genetic toolkits for meiosis and sexual reproduction. These findings shed new light on the evolution of this asexual and sexual complex.

Published: February 2024

Abstract

This research explores the process of generating artificial training data for the detection and classification of defective areas in X-ray computed tomography (XCT) scans in the agricultural domain using AI techniques. It aims to determine the minimum detectability limit for such defects through analyses regarding the Probability of Detection based on analytic XCT simulations. For this purpose, the presented methodology introduces randomized shape variations in surface models used as descriptors for specimens in XCT simulations for generating virtual XCT data. Specifically, the agricultural sector is targeted in this work in terms of analyzing common degradation or defective areas in rice products. This is of special interest due to the huge biological genotypic and phenotypic variations occurring in nature. The proposed method is demonstrated on the application of analyzing rice grains for common defects (chalky and pore areas).

Published: February 2024

Abstract
The primary objective of this study was to investigate the influence of different dietary lipids (sheep’s grease, olive oil, coconut oil, and corn oil) on specific biomarkers associated with metabolic syndrome in both healthy and diabetic rats. The study designed for 45 days, utilized a male diabetic wistar rat (body weight, 180-220 g) model induced by streptozotocin (45 mg/kg bw). The rats were divided into two sections: five non-diabetic and five diabetic groups, each containing six rats. The first group in each section serving as the control, received a standard diet. Both non-diabetic or diabetic groups, were provided with a standard diet enriched with 15% sheep fat, 15% coconut oil, 15% olive oil, and 15% corn oil, respectively for a duration of 45 days. Post-supplementation, it was observed that control rats exhibited a higher food intake compared to rats supplemented with fatty diet. However, rats fed with coconut oil, olive oil and sheep fat showed weight gain at the end of the experiment, in both healthy and diabetic groups. Coconut oil supplementation significantly (p≤0.05) increased HDL-C and total cholesterol level in diabetic groups compared to healthy group, it was confirmed by an increased PPAR-α and ABCA-1 protein level. Olive oil significantly decreased triglyceride, total cholesterol, HDL-C and LDL-C levels in diabetic rats when compared to sheep fat or coconut oil. Corn oil significantly decreased fasting glucose, total cholesterol and LDL-C levels compared to all other dietary fat supplementation. Corn and olive oil supplemented normal groups, found with significant increase in hepatic glucose-lipid oxidative metabolism associated protein, like FGF-21, MSH, ABCA-1, PPAR-γ and decreased lipogenesis proteins like, SREBP and PPAR-α levels. In contrast, sheep grease and coconut oil increased SREBP and PPAR-α expression in normal as well as diabetic groups. Most notably, sheep grease pretreated normal and diabetic groups resulted in increased inflammatory (MCP-1, IL-1β, TLR-4, TNF-α), and oxidative stress markers (LPO, GSH, GPx, SOD and CAT) associated with insulin resistance and cardiovascular diseases. In conclusion, the combination of olive oil and corn oil with the daily diet may play a significant role in arresting proinflammatory agents and metabolic complications.
