This research aims to develop a precise and efficient dispersive solid-phase microextraction (DSPE) technique using third-generation polyamidoamine (PAMAM) dendrimer-grafted nanoparticles to quantify benzoylurea pesticides in green tea, black tea, and oolong tea infusions. The extraction efficiency is optimized through single-factor adjustments of key parameters, including adsorbent quantity (5-20 mg), adsorption duration (5-20 min), desorbent identity (methanol, acetonitrile), volume (100-600 μL), sodium chloride concentration (0-10%, m/v), and sample solution pH (3-8). The optimized method demonstrates linearity in the range of 2-500 μg L-1, with limits of detection (LODs) ranging from 0.6-1.5 μg L-1 and limits of quantification (LOQs) from 2.0 5.0 μg L-1. Recovery rates of 81.2-96.0% are achieved, with intra-day relative standard deviations (RSDs) of 1.4-2.8% and inter-day relative standard deviations of 2.0-3.9%, indicating high accuracy and repeatability. The successful application of detecting residues in commercial tea samples underscores the strong potential of the technique to determine benzoylurea analyte levels. solidphase solid phase DSPE (DSPE thirdgeneration third generation PAMAM (PAMAM dendrimergrafted dendrimer grafted infusions singlefactor single factor parameters 520 5 20 (5-2 mg, mg , mg) min, min min) methanol, methanol (methanol acetonitrile, acetonitrile acetonitrile) 100600 100 600 (100-60 μL, μL μL) 010%, 010 0 10%, 10 (0-10% m/v, mv m/v m v m/v) 38. 38 3 8 .

Abstract Objective Monitoring the disease status of Epstein-Barr virus (EBV)-related hemophagocytic lymphohistiocytosis (HLH) patients is crucial. This study aimed to investigate the different strategies and outcomes of patients with EBV-HLH and re-elevated EBV-DNA. Method A retrospective analysis was conducted on 20 patients diagnosed with EBV-HLH. Clinical features, laboratory tests, treatments, plasma EBV-DNA levels, and outcomes were assessed. Three cases were highlighted for detailed analysis. Results Nine of the 20 patients had a re-elevation of EBV-DNA during treatment, and 55.5 % (5/9) experienced relapses. Patients with persistently positive plasma EBV-DNA (n = 4) and those with re-elevated EBV-DNA after conversion (n = 9) showed a significantly higher relapse rate compared to those with persistently negative EBV-HLH (n = 7) (p < 0.05). Among the highlighted cases, Case 1 exhibited plasma EBV-DNA re-elevation after four weeks of treatment without relapse, maintaining stability with the original treatment regimen, and eventually, his plasma EBV-DNA turned negative. In Case 2, plasma EBV-DNA was elevated again with a recurrence of HLH after L-DEP. Consequently, she underwent allogeneic hematopoietic stem cell transplantation and eventually achieved complete remission (CR) with negative plasma EBV-DNA. Case 3 experienced plasma EBV-DNA re-elevation after L-DEP but remained in CR, discontinuing chemotherapy without relapse. Conclusion The re-elevation of plasma EBV-DNA during EBV-HLH treatment poses challenges in determining disease status and treatment strategies. Optimal management decisions require a combination of the level of elevated EBV-DNA, the intensity of hyperinflammation, and the patient's immune function.

Tribo-electrostatic separation is a promising method for effectively utiliing low-grade magnesite resources by removing quartz and improving the grade of magnesite. To determine the charge-to-mass ratios of pure magnesite and quartz, a triboelectric measurement system was employed, and a laboratory tribo-electrostatic separation system was used to separate low-grade magnesite. The results showed that the maximum difference in charge-to-mass ratio between pure magnesite and quartz particles was observed after friction with polyvinyl chloride. The grade and recovery of magnesite increased with temperature and initially increased with increasing voltage, feed rate, and air flowrate before gradually decreasing. The optimal conditions resulted in a concentrate with 46.91% MgO content and 77.36% recovery, while the quartz content decreased from 7.02% to 1.95%. These experimental results demonstrate the effectiveness and potential of tribo-electrostatic separation in removing quartz and upgrading magnesite.

As one of the most important types of evidence at the scene of the crime, the rapid identification of the human bloodstain is of great significance to solve the criminal case. In this paper, the spectral data of different species of bloodstain samples including human, chicken and pig were acquired by using a hand-held near-infrared spectrometer. Then, the training models were established via convolutional neural network-support vector machine algorithm. Meanwhile, the traditional support vector machine, genetic algorithm-back propagation and random forest classification algorithms were also compared. The results showed that the prediction accuracy of convolutional neural network-support vector machine algorithm was the highest and the overall performance of the model was the best. The rapid detection method based on a handheld near-infrared spectrometer and convolutional neural network-support vector machine algorithm could identify the species of bloodstain efficiently, non-destructively, quickly and accurately and it provided a new technical reference for bloodstains detection and identification. crime case paper hand held nearinfrared near infrared Then networksupport network Meanwhile algorithmback back compared best efficiently nondestructively, nondestructively non destructively, destructively non-destructively

ABSTRACT The study aimed to investigate the effect of methionine deficiency on conventional nutrient composition, NO and NOS activity in the liver and kidney, and expression of genes related to the NF-κB signal pathway. One hundred 1-day-old broilers were divided into control and methionine deficiency group, and provided with a standard diet. The methionine-deficient group was fed with a methionine-deficient diet for 42 days. Moisture content, protein content, and crude lipid content were determined by freeze drying, the Kjeldahl method, and the ether extraction method. The concentration of NO was measured using the nitrate reductase method, and the activity of NOS was measured using colorimetry. mRNA expression of related genes in the NF-κB signal pathway was detected by reverse transcription-polymerase chain reaction (RT-PCR). The results showed the contents of crude protein and crude lipid in the liver and kidney of the methionine-deficient group were significantly higher than those in the control group (p<0.05 or p<0.01). There was no significant change in dry matter (p>0.05). Methionine deficiency resulted in significantly increased NO concentration and total nitric oxide synthase (TNOS) activities in the liver and kidney (p<0.01). In contrast, cNOS and inducible iNOS activities significantly decreased (p<0.01). The expression of NF-κB, TNF-α, IFN-γ, IL-1, and IL-6 mRNA, which are related to the NF-κB signal pathway of the methionine-deficient group, were significantly higher than those in the control group (p<0.05 or p<0.01). It is concluded that long-term feeding diets lacking methionine will lead to changes in nutrient composition and inflammatory injury of the liver and kidney.

Abstract Objective This study aims to develop a compound biomaterial to achieve effective soft tissue regeneration. Methodology Compound hyaluronic acid (CHA) and liquid horizontal-platelet-rich fibrin (H-PRF) were mixed at a ratio of 1:1 to form a CHA-PRF gel. Human gingival fibroblasts (HGFs) were used in this study. The effect of CHA, H-PRF, and the CHA-PRF gel on cell viability was evaluated by CCK-8 assays. Then, the effect of CHA, H-PRF, and the CHA-PRF gel on collagen formation and deposition was evaluated by qRT‒PCR and immunofluorescence analysis. Finally, qRT‒PCR, immunofluorescence analysis, Transwell assays, and scratch wound-healing assays were performed to determine how CHA, H-PRF, and the CHA-PRF gel affect the migration of HGFs. Results The combination of CHA and H-PRF shortened the coagulation time of liquid H-PRF. Compared to the pure CHA and H-PRF group, the CHA-PRF group exhibited the highest cell proliferation at all time points, as shown by the CCK-8 assay. Col1a and FAK were expressed at the highest levels in the CHA-PRF group, as shown by qRT‒PCR. CHA and PRF could stimulate collagen formation and HGF migration, as observed by fluorescence microscopy analysis of COL1 and F-actin and Transwell and scratch healing assays. Conclusion The CHA-PRF group exhibited greater potential to promote soft tissue regeneration by inducing cell proliferation, collagen synthesis, and migration in HGFs than the pure CHA or H-PRF group. CHA-PRF can serve as a great candidate for use alone or in combination with autografts in periodontal or peri-implant soft tissue regeneration.

Silver nanoparticles (Ag-NPs) can enter tumor cells through endocytosis and transfer to mitochondria, then disrupt mitochondrial function, damage deoxyribonucleic acid (DNA), and finally lead to cell death and apoptosis. As the Ag-NPs synthesized by Moringa peregrina leaf extract contain biomolecules such as flavonoids and terpenoids, they may suppress cancer by disrupting the flow of autophagy and inhibiting the differentiation of cancer cells, especially in apoptosis-resistant cancer cells. Accordingly, the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazoliumbromid (MTT) assay proved that Ag-NPs could inhibit the OVCAR-3 cell line in a timeand concentration-dependent manner. Real-time polymerase chain reaction (PCR) results showed that the ratio of the pro-apoptotic Bak1 gene to the anti-apoptotic Bclx gene increased about 10 times compared to the control. Also, the expression of the caspase-3 gene has increased about 18 times compared to the control. In addition, it was found that Ag-NPs can inhibit the progression of ovarian cancer cell lines and decrease the expression of the AKT1 gene by 0.08. And the more important point was the safety of Ag-NPs, which was checked by the lipid peroxidation method and it was confirmed that the treated hepatocytes did not have any significant difference in the production of malondialdehyde with the control and probably do not cause hepatotoxicity.

Objective: The advancement of neuroimaging and genetic research has revealed the presence of morphological abnormalities and numerous risk genes, along with their associations. We aimed to estimate magnetic resonance imaging-derived cortical thickness across multiple brain regions. Methods: The cortical thickness of 129 schizophrenia patients, 42 of their unaffected siblings, and 112 healthy controls was measured and the candidate genes were sequenced. Comparisons were made of cortical thickness (including 68 regions of the Desikan-Killiany Atlas) and genetic variants (in 108 risk genes for schizophrenia) among the three groups, and correlation analyses were performed regarding cortical thickness, clinical symptoms, cognitive tests (such as the N-back task and the logical memory test), and genetic variants. Results: Schizophrenia patients had significantly thinner bilateral frontal, temporal, and parietal gyri than healthy controls and unaffected siblings. Association analyses in target genes showed that four single nucleotide variants (SNVs) were significantly associated with schizophrenia, including thioredoxin-related transmembrane protein 2-catenin, cadherin-associated protein, delta 1 (SNV20673) (positive false discovery rate [PFDR] = 0.008) and centromere protein M (rs35542507, rs41277477, rs73165153) (PFDR = 0.030). Additionally, cortical thickness in the right pars triangularis was lower in carriers of the SNV20673 variant than in non-carriers (PFDR = 0.048). Finally, a positive correlation was found between right pars triangularis cortical thickness and logical memory in schizophrenia patients (r = 0.199, p = 0.032). Conclusions: This study identified regional morphological abnormalities in schizophrenia, including the right homologue of Broca’s area, which was associated with a risk variant that affected delta-1 catenin and logical memory. These findings suggest a potential association between candidate gene loci, cortical thickness, and schizophrenia.

Abstract Numerous studies have focused on microRNAs (miRNAs) in hepatocellular carcinoma (HCC). However, the specific role of miR-135a-5p in HCC has remained unclear. Thus, this study aimed to elucidate the role and mechanisms of action of miR-135a-5p in HCC. Transfected Huh-7 HCC cells were subjected to cell proliferation, apoptosis, migration, and invasion assays to investigate the role of miR-135a-5p and FOXO1 in modulating cellular functions. Additionally, tumor xenografts from nude mice were utilized in vivo to validate the in vitro findings. Downregulation of miR-135a-5p or upregulation of FOXO1 inhibited cell proliferation and metastasis of Huh-7 cells while promoting apoptosis. Conversely, upregulation of miR-135a-5p induced proliferation and metastasis of Huh-7 cells while suppressing apoptosis. Furthermore, FOXO1 was identified as a direct target of miR-135a-5p. Notably, downregulation of miR-135a-5p or upregulation of FOXO1 suppressed tumor growth in Huh-7 cells.

Abstract The flexibility matrix finds extensive application in detecting damage in civil and mechanical engineering structures, a focus explored in-depth within this paper. This study meticulously examines distinct components of the flexibility matrix, namely the proposed Diagonal of the Flexibility Matrix Vector (DFV) and a singular row/column of the flexibility matrix (RFV). Both DFV and RFV can be represented uniquely as a specialized form-a weighted combination of the Hadamard product of two mode shapes. Sensitivity analysis reveals that DFV undergoes a sharp change in proximity to damage, establishing it as a dependable indicator for pinpointing damage locations. Conversely, this characteristic is not consistently observed with RFV. The results of numerical simulations conducted on a 16-story frame structure corroborate the outcomes of the sensitivity analysis, underscoring the efficacy of DFV not only in localizing damage but also in gauging its severity. To illustrate the potential and limitations of DFV/RFV in practical scenarios, damage localization for the I-40 Bridge is provided. structures indepth depth paper (DFV rowcolumn row column .

Abstract For the design of scaled model and similarity prediction of vibration of 300,000m3 blast furnace gasholder body, based on energy method and discrete stiffening theory, the scaling principle relation of gasholder body free vibration are derived. By using the thickness scale factor of the gasholder body skin and rib is distorted, and utilizing the stiffness equivalence, respectively, gasholder body scaled models (stiffened rib equivalent to rectangle) with geometric distortion and with both geometric and material distortion are designed and fabricated respectively. The free vibration of distortion similarity prediction of gasholder body prototype is carried out by the method of simulation and test. Results show that both two kinds of gasholder body scaled models, can predict the prototype frequency more accurately by using the similarity coefficient calculated by the average bending stiffness of column, ring rib, and wind-resistant ring. The proposed design method and scaling principle relation for gasholder body scaled model with free vibration and distortion are suitable for the design of scaled model distortion and similar prediction of free vibration of longitudinal ring-stiffened large thin-walled cylindrical shells with T-shaped and I-shaped stiffeners. 300000m3 m 300 000m3 300,000m theory derived distorted equivalence respectively stiffened rectangle test column windresistant wind resistant ringstiffened thinwalled thin walled Tshaped T shaped Ishaped I stiffeners 300000m 30 000m 3

Resumo A mosca-branca é uma das pragas agrícolas mais difundidas no mundo. Os óleos essenciais podem ser usados para controlar esse inseto de forma ambientalmente responsável. A atividade fumigante, repelente e antioviposição de óleos essenciais extraídos com etanol de Trachyspermum ammi, Withania coagulans e Murraya koenigii contra Bemisia tabaci foi investigada neste estudo. No experimento, foram utilizadas três concentrações de óleo essencial (2,5 mg/mL, 5 mg/mL e 10 mg/mL). Trachyspermum ammi teve a maior porcentagem de morte de mosca-branca em experimentos de laboratório devido à sua toxicidade fumigante; a mesma tendência foi encontrada na toxicidade de contato e efeito repelente. A porcentagem de mortalidade aumenta à medida que a concentração de óleo essencial aumenta com o tempo do bioensaio. À medida que a concentração de óleo essencial cresce com o tempo de bioensaio, o mesmo acontece com a taxa de mortalidade. A maioria das moscas-brancas adultas escapou da estufa das plantas tratadas devido à maior concentração de óleo essencial. A maior repelência foi encontrada com óleo essencial de Trachyspermum ammi a 10 mg/mL. O óleo essencial apresentou a maior eficácia antioviposição contra moscas-brancas. Trachyspermum ammi teve o mais potente impedimento antioviposição, seguido por Withania coagulans em segundo lugar. Murraya koenigii terminou em terceiro com antioviposição moderada, o que afeta o número de ovos produzidos em relação ao controle. Como consequência, esses três óleos podem ser usados como um bioinseticida eficaz e ambientalmente aceitável para controlar B. tabaci.

Abstract Whitefly is one of the most widespread agricultural pests in the world. Essential oils might be used to control this insect in an environmentally responsible way. The fumigant, repellent, and anti-oviposition activity of ethanol-extracted essential oils of Trachyspermum ammi, Withania coagulans, and Murraya koenigii against Bemisia tabaci was investigated in this study. In the experiment, three essential oil concentrations (2.5 mg/mL, 5 mg/mL, and 10 mg/mL) were used. Trachyspermum ammi had the highest percentage of whitefly death in laboratory experiments due to its fumigant toxicity; the same tendency was found in contact toxicity and repellent effect. Mortality percent rises as the concentration of essential oil increases with bioassay time. As the concentration of essential oil grows with bioassay time, so does the mortality rate. The most adult whiteflies escaped from the treated plants' greenhouse due to the highest essential oil concentration. The greatest repellency was found with Trachyspermum ammi essential oil at 10 mg/mL. The essential oil had the greatest anti-oviposition efficacy against whiteflies. Trachyspermum ammi possessed the most potent anti-oviposition deterrent, followed by Withania coagulans in second place. Murraya koenigii finished third with moderate anti-oviposition, which affects the number of eggs produced in comparison to the control. As a consequence, these three oils might be used as an effective and environmentally acceptable bio-insecticide to control B. tabaci.

Abstract Background: Acid-sensing ion channel 1a (ASIC1a) plays a critical role in physiological and pathological processes. To further elucidate the biological functions of ASICs and their relationships with disease occurrence and development, it is advantageous to investigate and develop additional regulatory factors for ASICs. Methods: In this study, cation exchange chromatography was used to separate seven chromatographic components from Naja naja atra venom. Capillary electrophoresis was employed to detect that Ⅶ peak component containing a main protein Ⅶ-2, which could bind to ASIC1a. The analgesic effects of Ⅶ-2 protein were determined using hot plate methods, and ASIC1a expression in spinal cord tissue from rats with inflammatory pain was detected using western blot. Results: The purified Ⅶ-2 protein named Naja naja atra venom-Ⅶ-2 (NNAV-Ⅶ-2) was obtained by Sephadex G-50 gel filtration, which exhibited a single band on sodium dodecyl sulfate-polyacrylamide gel electrophoresis with a molecular weight of 6.7 kD. Remarkably, the NNAV-Ⅶ-2 protein demonstrated a significant analgesic effect and downregulated ASIC1a expression in the spinal cord tissue of rats with inflammatory pain. Conclusions: The analgesic mechanism of the NNAV-Ⅶ-2 protein may be associated with its binding to ASIC1a, consequently downregulating ASIC1a expression in neural tissues.

Abstract Objective The association between Papillary Thyroid Carcinoma (PTC) and coexistent Hashimoto’s Thyroiditis (HT) was controversial. The purpose of this study was to evaluate the presence of HT exerts any influence on the aggressiveness of PTC, and to establish a nomogram for predicting the possibility of aggressiveness in PTC. Methods 373 consecutive PTC patients with/without coexistent HT from January 2017 to December 2020 were retrospective reviewed. Patients’ clinicopathologic and sonographic characteristics were collected for univariate and multivariate analyses. A nomogram was established based on the risk factors for aggressiveness in PTC. Results Male (p= 0.001), tumor size >1.0 cm (p= 0.046) and lymph node metastasis (p= 0.018) were negatively associated with PTC coexisted with HT, while it was significantly positively associated with the frequence of multifocality (p= 0.010). Univariate and multivariate analyses suggested that age ≥55 years (p= 0.000), male (p= 0.027), HT (p= 0.017), tumor size >1.0 cm (p= 0.015), multifocality (p= 0.041), distance to capsular ≤0 cm (p= 0.050) and blood flow (Grade I: p= 0.044) were independent risk factors for predicting the aggressiveness in PTC. A nomogram according to these predictors was further developed and validated. The receiver operating characteristic curve (AUC = 0.734 and 0.809 for training and validation cohorts, respectively) and decision curve analyses indicated that the nomogram model was clinically useful. The calibration curve revealed that the nomogram exhibited an excellent consistency. Conclusions In this study, the coexistent HT might play a protective role in preventing the proliferation of PTC. Dispensable aggressive treatment may be reduced in PTC by pre-operative identification of sonographic and clinical characteristics and incorporating with the predicted nomogram model.
