The concentrations of Σ<sub>13</sub>tri-OPEs and Σ<sub>5</sub>di-OPEs in soil samples ranged from 39.60 to 730.52 ng/g dw and 2.25–6.94 ng/g dw, respectively. Tris (chloroethyl) phosphate was the predominant tri-OPE, while dibutyl phosphate was the most abundant di-OPE. The levels of OPEs pollution increased with the age of mulch film, highlighting the impact of the duration of mulch film usage on OPE accumulation. The type of fertilizer significantly impacted OPE levels. Soil samples treated with compound fertilizers showed the highest concentration of tri-OPEs, reaching up to 205.32 ng/g dry weight. In contrast, the highest concentration of di-OPEs was found in soil samples treated with water-soluble fertilizers, with a peak of 3.89 ng/g dry weight. Total organic carbon, pH, total nitrogen, and total phosphorus had minimal effect on OPEs levels. According to the Positive Matrix Factorization Model, the primary sources of OPEs included the use of pesticides, food packaging materials, and small-scale machinery (48.39 %), water and reclaimed water irrigation (17.68 %), the utilization of agricultural films (17.39 %), and atmospheric deposition and degradation processes (16.54 %). Compared to the moderate risks associated with compounds such as tri-2-ethyl phosphate, 2-ethylhexyl diphenyl phosphate, and tris(1-chloro-2-propyl) phosphate, tris(chloroethyl) phosphate exhibited a higher risk level in soil samples.

In this study, 12 kinds of bovine leather were prepared with varying FB sizes using Cr(III), Zr(IV) and aldehyde as the crosslinking agents along with different fillers such as rapeseed oil phosphate, polyacrylic acid and their combination. The experimental results revealed that the tear strength of leather was affected by the crosslinking agents, which could be further adjusted by the filler. Accordingly, a simple method using mercury intrusion porosimetry has been proposed for determining the FB size based on the crack-bridging model. Specifically, the tear strength of leather showed a strong correlation with the FB radius where the strength increased with the decrease in FB radius. This indicated that FBs served as the elementary units contributing to loading strength. These findings may facilitate the development of cleaner technologies for fabricating high-performance leather through the regulation of FB size.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":640,"journal":{"name":"Journal of Leather Science and Engineering","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://JLSE.SpringerOpen.com/counter/pdf/10.1186/s42825-024-00184-4","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143521646","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The identification of peptide with haematopoietic activity to ensure the efficiency of functional foods remains challenging because of the vast combinatorial potential of short peptides from collagen hydrolysates. In the present study, we identified a novel marker peptide (the I-1 peptide, GAAGLpGPK, p: hydroxyproline) for type I collagen with haematopoietic capabilities via theoretical sequence analysis and computational prediction of activity. The I-1 peptide was shown to increase the survival rate of haematopoietic stem cells following injury induced by 5-fluorouracil (5-FU), increasing the survival rate from 65.40 to 105.28%, thereby exhibiting significant haematopoietic activity. More importantly, the mechanism underlying the haematopoietic activity of the I-1 peptide was analogous to activate the JAK/STAT signalling pathway mediated by granulocyte‒macrophage colony‒stimulating factor. On this basis, a high-precision method for the detection of type I collagen hydrolysates was developed using the I-1 peptide (relative standard deviation = 1.57%). This study not only provides novel perspectives for the exploration of haematopoietic peptides but also offers a new methodology for controlling the bioactivity of collagen-based food products.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":640,"journal":{"name":"Journal of Leather Science and Engineering","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://JLSE.SpringerOpen.com/counter/pdf/10.1186/s42825-024-00188-0","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143489638","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The deviation of medial and lateral translational installation of the prosthesis during surgery is a common clinical phenomenon and an important factor in increasing the risk of prosthesis loosening. This study established a UKA finite element model and a bone-prosthesis fixation interface micromotion prediction model. The predicted medial contact force and joint motion of the knee joint from a patient-specific lower extremity musculoskeletal multibody dynamics model of UKA were used as boundary conditions. The effects of 9 femoral component medial and lateral translational installation deviations on the Von Mises stress of the proximal tibia, the contact stress, and the micro-motion of the bone prosthesis fixation interface were quantitatively studied. It was found that compared with the neutral position (a/A of 0.492), the lateral translational deviation of the femoral component significantly increased the tibial Von Mises stress and the bone-prosthesis fixation interface contact stress. The maximum Von Mises stress and the maximum contact stress of the fixation interface increased by 14.08% and 143.15%, respectively, when a/A was 0.361. The medial translational deviation of the femoral component significantly increased the bone-prosthesis fixation interface micro-motion. The maximum value of micromotion under the conditions of femoral neutral and medial translation deviation was in the range of 20-50 μm, which is suitable for osseointegration. Therefore, based on considerations such as the micromotion range suitable for osseointegration reported in the literature, the risk of reducing prosthesis loosening, and factors that may induce pain, it is recommended that clinicians control the mounting position of the femoral component during surgery within the safe range of 0-4 mm medial translation deviation.</p>","PeriodicalId":39324,"journal":{"name":"生物医学工程学杂志","volume":"42 1","pages":"105-112"},"PeriodicalIF":0.0,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143504653","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The system mainly comprises a ventilator airflow analyzer, an automated switch module for simulated lungs, and a test control platform. Under the control of testing software, this system can perform automated tests of critical performance parameters of ventilators and generate a final test report. To validate the effectiveness of the designed system, tests were conducted on two different brands of ventilators under four different operating conditions, comparing tidal volume, oxygen concentration, and positive end expiratory pressure accuracy using both the automated testing system and traditional manual methods. Bland-Altman statistical analysis indicated good consistency between the accuracy of automated tests and manual tests for all respiratory parameters.

With the computed tomography data from subjects, a three-dimensional femur-pelvis-sacrum model was reconstructed, and the individualized musculoskeletal dynamics was analyzed using the ergonomics software, which derived the human joint forces and completed the mechanic model. Then, this study established a dual-arm robot transfer platform to conduct subject transfer experiments, showing that the constructed mechanics model possessed higher accuracy than previous methods.

The existing segmentation approaches embrace massive parameters, sluggish inference speed, and huge memory consumption. To tackle this problem, we propose T <sup>2</sup>KD Attention U-Net (dual-Teacher Knowledge Distillation Attention U-Net), a lightweight semantic segmentation method combined double-path joint distillation in breast ultrasound images. Primarily, we designed two teacher models to learn the fine-grained features from each class of images according to different feature representation and semantic information of benign and malignant breast lesions. Then we leveraged the joint distillation to train a lightweight student model. Finally, we constructed a novel weight balance loss to focus on the semantic feature of small objection, solving the unbalance problem of tumor and background. Specifically, the extensive experiments conducted on Dataset BUSI and Dataset B demonstrated that the T <sup>2</sup>KD Attention U-Net outperformed various knowledge distillation counterparts.
