Melatonin’s impact on the root response to Cd stress, which is the first organ to detect its presence, has been less studied. This study aims to investigate the effects of melatonin pretreatment on the root strategies of <i>Malva parviflora</i> in response to Cd stress, focusing on the mechanisms of heavy metal tolerance. The plants, 42 days post-germination, were subjected to a 48-h pretreatment with 50 μM melatonin in a complete nutrient solution under controlled growth conditions. Following pretreatment, plants were exposed to a nutrient solution containing 50 μM Cd for 8 days. Comparative analyses were conducted on root length, weight, anatomical features, Cd content, Cd subcellular distribution, nutrient absorption, glutathione, and lignin. Melatonin pretreatment significantly enhanced root length and weight under Cd stress. It also increased the xylem and phloem area in the roots and promoted the absorption and translocation of essential nutrients such as Fe, Zn, Ca, and Mg to the shoots. Additionally, there was a marked increase in glutathione content and Cd proportion in the cell wall and organelle fractions in melatonin-pretreated roots. Notably, melatonin reduced overall plant Cd content and its translocation from roots to shoots, while decreasing root lignin content. This study demonstrates that melatonin plays an important role in managing Cd toxicity by improving morphological, anatomical, and biochemical characteristics of roots under Cd stress. The findings suggest that melatonin pretreatment can effectively alter Cd subcellular distribution, thereby mitigating its harmful effects in plants.</p></div>","PeriodicalId":491,"journal":{"name":"Biometals","volume":"38 3","pages":"997 - 1017"},"PeriodicalIF":3.6,"publicationDate":"2025-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143955992","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study included 2965 participants for a cross-sectional study from the NHANES. The weighted quantile sum (WQS) regression, bayesian kernel machine regression (BKMR), machine learning models (support vector machines, random forests, decision trees, and XGBoost), restricted cubic spline (RCS), and logistic regression were applied to comprehensively evaluate the performance of urinary metals in predicting chronic cough risk. Finally, the mediation effect model was employed to evaluate the role of systematic inflammation in the relationship between urinary cadmium and the risk of chronic cough. Urinary cadmium correlated with an increasing risk of chronic cough in the multivariate logistic regression model (OR: 2.83, 95% CI: 1.60–4.99). Both the WQS regression and BKMR consistently suggested a positive relationship between urinary mixed metal and chronic cough risk. Among the four machine learning models used to evaluate urinary metals and the risk of chronic cough, the random forests model showed better predictive performance (AUC = 0.69). The random forests suggested that the top five important indicators for predicting chronic cough risk were urinary cadmium, thallium, molybdenum, cesium, and uranium. Finally, the mediation effect model suggested that the systematic inflammation (lymphocytes: 4.24%, systemic immune inflammation index: 5.11%) partially mediated the relationship between urinary cadmium and chronic cough risk. This study discovered that urinary cadmium was elevated in correlation with the increasing risk of chronic cough. Systematic inflammations may partially mediate this association. Improving exposure to urinary cadmium may reduce the risk of chronic cough.</p></div>","PeriodicalId":491,"journal":{"name":"Biometals","volume":"38 3","pages":"983 - 995"},"PeriodicalIF":3.6,"publicationDate":"2025-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143957031","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address these objectives, we collected femoral neck specimens from 23 individuals, namely 11 individuals with a positive history of contralateral hip fracture (9 women and 2 men, mean age 77.7 ± 8.1 years) and 12 individuals without fractures (10 women and 2 men, mean age 79.5 ± 5.6 years). All samples were subject to microcomputed tomography (micro-CT) to evaluate bone microarchitecture and inductively coupled plasma–mass spectrometry to determine tissue concentrations of metal(oid)s. In the fully adjusted model (adjusted for bone volume, age, and calcium tissue concentration), individuals with hip fractures exhibited higher aluminum levels (p = 0.047) and lower vanadium levels (p < 0.001). Individuals who sustained fragility fractures also showed lower BV/TV, Tb.Th, Tb.N, and higher Tb.Sp in the femoral neck trabeculae compared with the control group. Several different metal(oid)s were associated with altered patterns of trabecular microarchitecture. In summary, higher aluminum and lower vanadium concentrations in the trabeculae of the femoral neck provide a potential background for the gradual increase in fracture risk. Correlational analysis revealed an association between exposure to certain metals and deteriorated trabecular microarchitecture; however, larger studies are needed to determine the elements independently affecting bone microarchitecture.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":491,"journal":{"name":"Biometals","volume":"38 3","pages":"965 - 981"},"PeriodicalIF":3.6,"publicationDate":"2025-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143960120","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, their biocompatibility can be compromised by corrosion, which releases toxic metal ions that may provoke adverse biological reactions and contribute to implant failure. This study introduces a novel metal-ceramic composite based on a high-chromium FeCrAl alloy, specifically engineered to form a thermally grown α-Al₂O₃ surface layer. This design aims to significantly enhance biocompatibility and corrosion resistance for potential biomedical implant applications. Samples of the Fe-44Cr-5Al alloy were produced using an arc melting process. The mechanically polished alloy coupons were given a mirror-like finish and underwent high-temperature oxidation at 1050 °C for 20 h in laboratory air to develop a dense and adherent α-Al₂O₃ layer. Both bare and oxidized samples were immersed in artificial saliva at 37 °C for two months to assess their corrosion resistance under simulated oral conditions. Biocompatibility was evaluated through cytotoxicity and mitotic activity tests using primary human gingival fibroblasts cultured on both the bare and oxidized samples. The results showed that thermal oxidation effectively produced a uniform, adherent, and stable α-Al₂O₃ layer on the surface of the FeCrAl alloy. The oxidized samples demonstrated superior corrosion resistance, with negligible metal ion release and no formation of corrosion products. In contrast, the bare (unoxidized) alloy exhibited extensive corrosion and significant ion release. Cytotoxicity tests indicated that the oxidized alloy supported normal cell adhesion, proliferation, and morphology comparable to control samples. Although a slight reduction in cell proliferation was noted on the oxidized metal surface, overall bioactivity remained high. Structural and morphological analyses were performed using scanning electron microscopy (SEM), energy-dispersive spectroscopy (EDS), X-ray diffraction (XRD), and Grazing Incidence X-ray Diffraction (GIXRD) to confirm the formation and integrity of the oxide layer.
