RESUMO

Unsafe behavior among construction personnel poses significant risks in petroleum engineering construction projects. This study addresses this issue through the application of a multi-field coupled homogeneous analysis model. By conducting case analyses of petroleum engineering construction accidents and utilizing the WSR methodology, the influencing factors of unsafe behaviors among construction personnel are systematically categorized into organizational system factors, equipment management factors, and construction personnel factors. Subsequently, employing Risk coupling theory, the study delves into the analysis of these influencing factors, discussing their coupling mechanisms and classifications, and utilizing the N-K model to elucidate the coupling effect among them. Furthermore, a novel approach integrating coupling analysis and multi-agent modeling is employed to establish an evolutionary model of construction personnel's unsafe behavior. The findings reveal that a two-factor control method, concurrently reinforcing equipment and construction personnel management, significantly mitigates unsafe behavior. This study provides valuable insights into the evolution of unsafe behavior among construction personnel and offers a robust theoretical framework for targeted interventions. Significantly, it bears practical implications for guiding safety management practices within petroleum engineering construction enterprises. By effectively controlling unsafe behaviors and implementing targeted safety interventions, it contributes to fostering sustainable development within the petroleum engineering construction industry.

RESUMO

Background: Gallbladder carcinoma (GBC) is a formidably aggressive malignancy. Circular RNAs (circRNAs) play crucial regulatory roles in cancer. NGFR is a novel circRNA implicated in various types of cancers. The primary goal of this study was to elucidate the role of NGFR in GBC. Methods: NGFR variants exhibiting discernible discrepancies were identified using RNA sequencing and validated using real-time PCR. Cell proliferation was assessed using 5-ethynyl-2'-deoxyuridine and Cell Counting Kit-8 assays. The ferroptotic phenotype was characterized by assessing the reactive oxygen species and Fe2+ levels. Western blotting was used to analyze ferroptosis-associated proteins. Superoxide dismutase, malondialdehyde, and glutathione levels were measured using commercially available reagent kits. The severity of mitochondrial damage was evaluated by assessing JC-1, MitoSOX, and ATP activities. Results: NGFR was upregulated, and its suppression inhibited cell proliferation and increased Fe2+ levels in GBC cells. Furthermore, NGFR downregulation disrupted mitochondrial function. Conclusion: Circular RNA NGFR can impede the advancement of GBC by modulating the ferroptotic phenotype, thereby potentially offering a novel avenue for the clinical diagnosis and treatment strategies of GBC.

RESUMO

Based on the nonlinear algorithmic theory, the R-SVM water source discrimination model and prediction method were established by using the piper qualitatively to compare the differences between the ionic components and R-type factor approximation indicator input dimensions. Taking the mine water samples of Zhaogezhuang Coal Mine as an example, according to the chemical composition analysis of the water samples from different monitoring points, six indexes of Na+, Ca2+, Mg2+, Cl-, SO42- and HCO3- were selected as the discrimination factors. According to the water characteristics of each aquifer and the actual needs of discrimination, the water inrush sources in the mining area were divided into four categories: The goaf water is class I, Ordovician carbonate is class II, Sandstone fracture water from the 13 coal system is class III, and Sandstone fracture water from the 12 coal system is class IV. Taking 56 typical water inrush samples as training samples, 11 groups for prediction samples, establish the input index as typical ion content, output as water source type, using SPSS statistics and MATLAB to realize the R-SVM water source discriminant analysis model, automatically establishing the mapping relationship between the water quality indexes and the evaluation standards, which can achieve the purpose of rapid and accurate discrimination of the water sample data. The results showed that the accuracy of the R-SVM model classification was 90.90% in the verification of the water source discrimination example of Zhaogezhuang mine and the coupled model has high accuracy, good applicability and discriminant ability, and has certain guiding significance for the prevention and control of water damage and the related field work.

RESUMO

Luminescent ferroelectrics are holding exciting prospect for integrated photoelectronic devices due to potential light-polarization interactions at electron scale. Integrating ferroelectricity and long-lived afterglow emission in a single material would offer new possibilities for fundamental research and applications, however, related reports have been a blank to date. For the first time, we here achieved the combination of notable ferroelectricity and afterglow emission in an organic-inorganic hybrid material. Remarkably, the presented (4-methylpiperidium)CdCl3 also shows noticeable antiferroelectric behavior. The implementation of cationic customization and halogen engineering not only enables a dramatic enhancement of Curie temperature of 114.4 K but also brings a record longest emission lifetime up to 117.11 ms under ambient conditions, realizing a leapfrog improvement of at least two orders of magnitude compared to reported hybrid ferroelectrics so far. This finding would herald the emergence of novel application potential, such as multi-level density data storage or multifunctional sensors, towards the future integrated optoelectronic devices with multitasking capabilities.

RESUMO

The past decade has witnessed the significant efforts in novel material discovery in the use of data-driven techniques, in particular, machine learning (ML). However, since it needs to consider the precursors, experimental conditions, and availability of reactants, material synthesis is generally much more complex than property and structure prediction, and very few computational predictions are experimentally realized. To solve these challenges, a universal framework that integrates high-throughput experiments, a priori knowledge of chemistry, and ML techniques such as subgroup discovery and support vector machine is proposed to guide the experimental synthesis of materials, which is capable of disclosing structure-property relationship hidden in high-throughput experiments and rapidly screening out materials with high synthesis feasibility from vast chemical space. Through application of our approach to challenging and consequential synthesis problem of 2D silver/bismuth organic-inorganic hybrid perovskites, we have increased the success rate of the synthesis feasibility by a factor of four relative to traditional approaches. This study provides a practical route for solving multidimensional chemical acceleration problems with small dataset from typical laboratory with limited experimental resources available.

RESUMO

BACKGROUND: Postmortem muscle moisture loss leads to a decrease in carcass weight and can adversely impact overall meat quality. Therefore, it is critical to investigate water holding capacity (WHC) to enhance meat quality. Current research has primarily focused on examining the correlation between signaling molecules and meat quality in relation to the glycolysis effect on muscle WHC. But there exists a significant knowledge gap regarding the mechanism of WHC in Jersey cattle-yak meat. RESULTS: Jersey cattle-yak meat pH decreased and then increased during postmortem aging. Lactate content, cooking loss, pressing loss, drip loss and centrifuging loss of Jersey cattle-yak meat increased and then decreased during postmortem aging. The glycogen content of Jersey cattle-yak meat was significantly higher than that of yak meat at 6-120 h, being 8.40% higher than that of yak meat at 120 h. The activity of key glycolytic enzymes hexokinase (HK), pyruvate kinase (PK), phosphofructokinase (PFK) and lactate dehydrogenase (LDH) in Jersey cattle-yak meat was lower than that in yak meat. Correlation analysis showed that Jersey cattle-yak meat WHC was positively correlated with the activity of HK, PK, PFK and LDH. CONCLUSIONS: The WHC of Jersey cattle-yak meat was higher than that of Gannan yak meat, and it was significantly positively correlated with the activity of key enzymes of the glycolytic signaling pathway. Therefore, the glycolysis rate can be reduced by inhibiting enzyme activity to improve Jersey cattle-yak meat WHC and meat quality. © 2023 Society of Chemical Industry.

RESUMO

BACKGROUND: /Objective: We aimed to evaluate whether additional intralesional bleomycin injections benefit children with proliferative infantile hemangiomas (IHs). METHODS: In this retrospective case-control study, we examined the medical records of 216 infants who were followed up for proliferative IH. Patients in group 1 were treated with propranolol orally at 2 mg/kg/day. Group 2 was treated with oral propranolol combined with intralesional bleomycin injections. RESULTS: We retrospectively reviewed 95 and 121 patients in groups 1 and 2, respectively. No significant differences were observed between both groups regarding visiting age, sex, lesion thickness, or risk site. The overall cure rates in groups 1 and 2 were 77.89% (74/95) and 84.30% (102/121), respectively. The overall distribution of the length of cure significantly differed between both groups (P = 0.035). From the survival analysis (P = 0.026), the median survival time was 198 days (95% confidence interval (CI) 174.46-221.54) for group 1 and 139 days (95% CI 114.58-163.42) for group 2. The effect of treatment modality (hazard ratio (HR) = 1.41, P = 0.031) and risk site on survival time (HR = .54, P < 0.001) was significant. CONCLUSION: No significant differences were observed in the resolution of proliferative IH; however, intralesional bleomycin injection with systemic propranolol for proliferative IH treatment may provide a more rapid resolution.

RESUMO

Hybrid organic-inorganic perovskite (HOIP) ferroelectric materials have great potential for developing self-powered electronic transducers owing to their impressive piezoelectric performance, structural tunability and low processing temperatures. Nevertheless, their inherent brittle and low elastic moduli limit their application in electromechanical conversion. Integration of HOIP ferroelectrics and soft polymers is a promising solution. In this work, a hybrid organic-inorganic rare-earth double perovskite ferroelectric, [RM3HQ]2RbPr(NO3)6 (RM3HQ = (R)-N-methyl-3-hydroxylquinuclidinium) is presented, which possesses multiaxial nature, ferroelasticity and satisfactory piezoelectric properties, including piezoelectric charge coefficient (d33) of 102.3 pC N-1 and piezoelectric voltage coefficient (g33) of 680 × 10-3 V m N-1. The piezoelectric generators (PEG) based on composite films of [RM3HQ]2RbPr(NO3)6@polyurethane (PU) can generate an open-circuit voltage (Voc) of 30 V and short-circuit current (Isc) of 18 µA, representing one of the state-of-the-art PEGs to date. This work has promoted the exploration of new HOIP ferroelectrics and their development of applications in electromechanical conversion devices.

RESUMO

OBJECTIVE: At present, bleomycin has been widely used in the treatment of Lymphatic Malformations (LMs). This study aims to perform a meta-analysis to investigate the effectiveness and influencing factors of bleomycin in the treatment of LMs. METHODS: We conducted a systematic review and meta-analysis to clarify the relationship between bleomycin and LMs. PubMed, ISI Web of Science and MEDLINE were searched. RESULTS: A total of 21 studies (including 428 cases) about bleomycin sclerotherapy for LMs were included in the current meta-analyses. We calculated pooled effective rate and 95% Confidence Interval (95% CI) using random effects model to evaluate the relations between bleomycin and LMs. The results suggested that the effective rate of bleomycin was the combined effective rate was 84.0% (95% CI 0.81‒0.87) and ranged from 39% (95% CI 0.22‒0.56) to 94% (95% CI 0.87-1.02). The heterogeneity among the studies was substantial (I2=61.7%, p= 0.000). In subgroup analyses, it was observed that among retrospective study and prospective study, the estimated effective rate was 80.0% (95% CI 0.76‒0.84) and 91.0% (95% CI 0.85‒0.97), respectively. In terms of the dosage, the combined effective rates of weight-based group and fixed-dose group were 86% (95% CI 0.83‒0.90) and 74.0% (95% CI 0.66‒0.82), respectively. There was no significant publication bias in Egger's test (p=0.059, 95% CI -3.81 to 0.082), but Begg's test did (p=0.023), and the funnel plot is asymmetric. CONCLUSION: Our study suggested that bleomycin was safe and effective in the treatment of LMs and was primarily dose dependent.

RESUMO

Defect engineering is considered an effective method to adjust the photocatalytic properties of materials. In this work, we synthesized the vacancy-rich ZnO rods with (100) planes via the melamine-assisted thermal activation method. A high concentration of oxygen vacancies was successfully introduced into non-polar oriented ZnO rods by calcination. The effect of oxygen vacancy on the photocatalytic properties of non-polar-oriented ZnO rods was investigated. Raman and XPS spectra revealed the formation of oxygen vacancies in the ZnO. The results showed that the growth habit and defects in ZnO can be controlled by changing the ratio of ZnO to melamine. The higher ratio of ZnO to melamine led to more amounts of (100) planes and oxygen vacancies in ZnO, and it reached the highest when the ratio was 1.2:1. When the ratio was 1.2:1, ZnO exhibited a high methyl orange degradation rate (95.8%). The differences in oxygen vacancy concentration and non-polar planes were responsible for the improvement in photocatalytic performance. ZnO exhibited good stability and regeneration capacity. After recycling four times, the degradation rate was still at 92%. Using the same method, vacancy-rich α-Fe2O3 was obtained. This work could offer a new and simple strategy for designing a photocatalyst with oxygen vacancies.

RESUMO

OBJECTIVE: This study aims to perform a meta-analysis to figure out the efficacy of OK-432 sclerotherapy between Macrocystic (MAC) lymphangiomas and Microcystic (MIC) lymphangiomas. METHODS: We conducted a systematic review and meta-analysis to clarify the relationship between OK-432 and lymphangiomas. PubMed and ISI Web of Science were searched from inception to May 2022. Joanna Briggs Institute (JBI) manual was used to evaluate the risk of bias. We calculated pooled Relative Risks (RR) and 95% Confidence Interval (95% CI) using random effects model to evaluate the relations between OK-432 and lymphangiomas. RESULTS: A total of 11 studies (including 352 cases) about OK-432 sclerotherapy for lymphangioma were included in the current meta-analyses. The results suggested that the efficacy of OK-432 was significantly in MAC lesions than in MIC (RR=1.51, 95% CI 1.298-1.764), with significant moderate degrees of heterogeneity among 11 studies (I2=51.2%, p=0.025). Subgroup analyses suggested that there was significant association in both retrospective studies (RR=1.26, 95% CI 1.03-1.53) and classification (by 1 cm) (RR=1.37, 95% CI 1.04-1.80) were associated with the efficacy of OK-432. CONCLUSION: To our knowledge, our study represents the first meta-analysis examining the efficacy of OK-432 in the treatment of different types of LMs. However, the regional differences and the age differences of the subjects are the main limitations of this study and should be avoided in further research. Our results suggested that OK-432 sclerotherapy for macrocystic lymphangiomas was more effective.

RESUMO

Background: Anticoagulant treatment is used to treat and prevent venous thromboembolism (VTE). However, the relative effectiveness of newer anticoagulants vs. warfarin has not been appraised. Objective: The aim was to evaluate the safety and efficacy of rivaroxaban for VTE in comparison to warfarin. Materials and methods: From January 2000 until October 2021, all related studies were collected by EMBASE, the Cochrane Library, PubMed and Web of Scienceand. During the review process, two reviewers independently analyzed the included studies, including quality evaluation, screening and data extraction. We focused on VTE events as our primary outcomes. Results: In total, 20 trials were retrieved. These studies involved 230,320 patients, of which 74,018 received rivaroxaban and 156,302 received warfarin. Compared with warfarin, the incidence of VTE in rivaroxaban is significantly lower (risk ratio (RR) 0.71, 95% confidence interval (CI) [0.61, 0.84]; P < 0.0001, random effect model), and significantly reduced major [RR: 0.84, 95% CI (0.77, 0.91); P < 0.0001, fixed effect model] and nonmajor [RR: 0.55, 95% CI (0.41, 0.74); P < 0.0001, fixed effect model] bleeding. No significant differences in all-cause mortality between the two groups [RR: 0.68, 95% CI (0.45, 1.02); P = 0.06, fixed effect model]. Conclusion: Rivaroxaban significantly reduced the incidence of VTE compared to warfarin in this meta-analysis. In order to verify these findings, larger sample sizes are required in well-designed studies.

RESUMO

Purpose: To assess the effectiveness and safety of transcatheter arterial sclerosing embolization (TASE) for the treatment of subglottic hemangiomas that did not respond appreciably to propranolol. Materials and Methods: This study was a retrospective analysis. Of the 101 patients with subglottic hemangiomas admitted to our center, 10 (4 male and 6 female) patients were included in this study. All these patients underwent arterial embolization using Pingyangmycin and polyvinyl alcohol particles (300-500 µm). All patients were examined 1 month after the last treatment and monthly thereafter. Results: TASE treatment was technically successful in all patients. Ten lesions were located in the subglottic region. The blood supply included the superior thyroid artery, brachiocephalic trunk, facial artery, and ascending pharyngeal arteries. The median maximal diameter of the hemangiomas significantly decreased from 8.5 mm before treatment to 2 mm after TASE (P <.05). The degree of laryngeal obstruction improved in all patients. No serious complications were noted. One patient developed fever postoperatively, and three patients had a mild cough. Conclusions: For even subglottic hemangiomas with suboptimal efficacy of propranolol, TASE significantly reduced the size of hemangiomas with minimal adverse effects. It had a positive effect on the improvement of airway stenosis caused by subglottic hemangioma with poor effect of oral propranolol.

RESUMO

Objectives: Delayed cerebral ischemia (DCI) contributes to poor aneurysm prognosis. Subarachnoid hemorrhage and DCI have irreversible and severe consequences once they occur; therefore, early prediction and prevention are important. We investigated the risk factors for postoperative complications of DCI in patients with aneurysmal subarachnoid hemorrhage (aSAH) requiring mechanical ventilation in intensive care and validated a prediction model. Methods: We retrospectively analyzed patients with aSAH who were treated in a French university hospital neuro-ICU between January 2010 and December 2015. The patients were randomized into a training group (144) and verification groups (60). Nomograms were validated in the training and verification groups, where receiver operating characteristic curve analysis was used to verify model discrimination; calibration curve and Hosmer-Lemeshow test were used to determine model calibration; and decision curve analysis (DCA) was used to verify clinical validity of the model. Results: External ventricular drain (EVD), duration of mechanical ventilation, and treatment were significantly associated in the univariate analysis; EVD and rebleeding were significantly associated with the occurrence of DCI after aSAH. Binary logistic regression was used to select five clinicopathological characteristics to predict the occurrence of DCI in patients with aSAH requiring mechanical ventilation nomograms of the risk of DCI. Area under the curve values for the training and verification groups were 0.768 and 0.246, with Brier scores of 0.166 and 0.163, respectively. Hosmer-Lemeshow calibration test values for the training and verification groups were x 2 = 3.824 (P = 0.923) and x 2 = 10.868 (P = 0.285), respectively. Calibration curves showed good agreement. DCA indicated that the training and verification groups showed large positive returns in the broad risk range of 0-77% and 0-63%, respectively. Conclusions: The predictive model of concurrent DCI in aSAH has theoretical and practical values and can provide individualized treatment options for patients with aSAH who require mechanical ventilation.

RESUMO

Background: Intralesional injection of lauromacrogol has proven to be an efficient treatment method for infantile hemangioma. This study aims to explore a novel injection therapy and evaluate its efficacy and complications. Methods: The medical records of 368 children with infantile hemangioma who received a lauromacrogol injection from January 2021 to April 2022 were retrospectively analyzed. All patients were reviewed every 4 weeks, and their condition was assessed according to symptoms and medical records. The patient's age, lesion type, location, size and thickness, lesion photographs, ultrasound, and complications were recorded. Results: Among the 368 infants who accept sclerotherapy with lauromacrogol, 226(61.4%)achieved excellent regression. In total, 108(29.4%)cases achieved good regression. 24(6.5%)achieved complete moderate regression. 10(2.7%)achieved poor regression. The reported incidence of adverse events was 4.9% and severe complications were not observed. Before and after three courses of treatment, the median vascular endothelial growth factor levels were 104.12 pg/ml and 28.982 pg/ml. There was a significant difference between the two groups (P=0.0043). Conclusions: The results showed that this novel injection therapy a safe and effective treatment method. The therapy accelerated the regression of infantile hemangiomas without serious complications.

RESUMO

Objective: Glioblastoma is one of the most common and fatal malignancies in adults. Current treatment is still not optimistic. Glioblastoma (GBM) transports RNA to platelets in the blood system via microvesicles, suggesting that platelet RNA can be a potential diagnostic and therapeutic target. The roles of specific platelet RNAs in treatment of GBM are not well understood. Methods: Platelet RNA profiling of 8 GBM and 12 normal samples were downloaded from the GEO database. Differentially expressed genes (DEGs) were identified between tumors and normal samples. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses were performed to elucidate the functions of up- and downregulated genes. miRNA was predicted by miRTarBase, TargetScan, and miRDB databases. circBase and circBank were used for circRNA prediction. ceRNA (circRNA-mRNA-miRNA) network was constructed to investigate the potential interactions. Results: 22 genes were upregulated and 9 genes were downregulated. There are only two genes (CCR7 and FAM102A) that connect to miRNAs (hsa-let-7a-5p, hsa-miR-1-3p). We assessed the overall survival rates by Kaplan-Meier plotter, and relative expression of GBM and subtypes for overlapped mRNA (CCR7 and FAM102A) were evaluated, and further, we obtained circRNAs (has-circ-0015164, hsa-circ-0003243) by circBank and circBase and bind sites through the CSCD database. Finally, a ceRNA network (circRNA-mRNA-miRNA) was constructed based on 2 miRNAs, 2 mRNAs, and 2 circRNAs by Cytoscape. This study focused on potential mRNA and ceRNA biomarkers to targeted treatment of GBM and provided ideas for clinical treatment through the combination of hematology and oncology. Conclusion: The findings of this study contribute to better understand the relationship between GBM and the blood system (platelets) and might lay a solid foundation for improving GBM molecule and gene diagnosis and prognosis.

RESUMO

The hybrid rare-earth double perovskite (HREDP) system provides great convenience for the construction of multifunctional materials. However, suffering from the high symmetry of their intrinsic structure, HREDPs face the challenges in the realization and optimization of ferroelectric and piezoelectric properties. For the first time, after a systematic investigation of the chirality transformation principle, it is found that the introduction of chirality is an efficient strategy for the targeted construction of multifunctionality, which simultaneously increases the possibility of obtaining multiaxial ferroelectricity and ferroelasticity, and effectively realizes a large piezoelectric response. Moreover, chirality induced ferroelasticity will also achieve excellent magnetic or optical response driven by pressure-sensitive. To verify the feasibility of the above ideas, by using rare-earth ions (Ce3+ ) and suitable chiral organic cations, a new HREDP, (R-N-methyl-3-hydroxylquinuclidinium)2 RbCe(NO3 )6 (R1) is successfully designed, in which ferroelasticity, multiaxial ferroelectricity, satisfactory piezoelectric response, and the pressure-driven single-ion magnetics switch are simultaneously achieved for the first time. This work shows that the induction of chirality and the HREDP system provide an effective strategy and ideal platform for the expansion and optimization of the functions in perovskite ferroelectrics.
