Iron fortification of meat and meat products has emerged as an effective strategy to combat this issue. This review explores the process and benefits of iron fortification, focusing on the types of iron compounds suitable for fortification, such as ferrous sulfate and ferric pyrophosphate, their bioavailability, and their impact on the sensory and nutritional qualities of meat products. Technological challenges and solutions, including encapsulation, chelation, and microencapsulation techniques, have been examined to minimize their negative impacts on sensory qualities. This review also discusses the regulatory framework governing iron fortification and consumer acceptance. Analytical methods for determining iron content, such as spectrophotometric and colorimetric detection, are discussed. Although iron-fortified meat products offer health benefits, sensory aspects and consumer acceptance are important considerations. This review provides a comprehensive understanding of the role and significance of iron fortification in meat products as a public health intervention to address iron deficiency.</p>","PeriodicalId":491,"journal":{"name":"Biometals","volume":" ","pages":""},"PeriodicalIF":4.1,"publicationDate":"2025-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142998083","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}

In the single-metal model, BLR and GLM commonly showed positive significant correlations between four metals (As, Mo, Se, Sn) in urine and BMD. Strong correlations between five metals (Mn, Co, As, Se, Mo) in blood and urine were observed (P ≤ 0.05). The BKMR model indicated a predominant synergistic effect of urine Mo and Sn, increased co-exposure to these metals is associated with a higher trend of BMD.

Mercury's unique ability to interfere with crucial enzymatic processes at deposition sites is a vital feature of these models. The strong affinity for the sulfhydryl moieties of enzyme catalytic sites leads to enzyme inactivation through permanent covalent modifications. This inactivation can have catastrophic effects on an organism's metabolic functions.

A total of 90 CRC patients and 97 controls were involved in the present study.

CRC patients are characterized by lower serum Ca, Fe, Se, and Zn, as well as higher serum Co, Cu, Mg, V, and Cu/Zn ratio compared to healthy controls. The lowest serum Zn levels and the highest Cu concentration and Cu/Zn ratio were observed in patients with the largest tumor size. Regression analysis demonstrated that tumor size is a significant negative predictor of serum Se levels, being positively associated with serum Cu/Zn values. The degree of metastasis to regional lymph nodes was inversely associated with circulating Ca, Co, Mg, Zn, and Mn levels. Serum Mg and Mn levels were positively associated with the stage of the disease and tumor location, respectively. Cancerous tissue Ca and Mo levels were lower, while Mg content was higher compared to healthy adjacent tissues. In cancerous tissues a constant but non-significant trend to elevation of tissue Zn content with increasing tumor size was observed. In addition, serum Cu, Zn, and Cu/Zn values positively correlated with the respective tumor values.

An octahedral environment encircling metal complexes has been demonstrated by the findings of multiple spectroscopic approaches that were employed to demonstrate the structure of the metal complexes. The Coats–Redfern method of thermal analysis was employed to carry out the kinetic and thermodynamic calculations. The crystalline size of ligand was 36.67 nm and for the metal complexes it varies from 22.43 to 49.21 nm. To assess the biological effectiveness of these compounds, molecular docking studies were emanated. The docking binding studies were established through the interaction of metal complexes with human cancer protein, such as 3W2S (ovarian cancer) and 4ZVM (breast cancer). The results exemplified that the complexes are more efficient towards ovarian cancer (3W2S) in contrast to breast cancer (4ZVM) while among complexes, the nickel acetate (− 7.0 kcal/mol) and copper acetate (− 7.9 kcal/mol) complex were more efficient towards 4ZVM and 3W2S receptors respectively. Additionally, DNA binding studies against 1BNA receptor protein was examined from docking evaluations and the finding concludes the highest efficiency of nickel (− 8.1 kcal/mol) complexes.

In the present study, effect of copper stress on augmentation in the antibiotic resistance of A. baumannii MCC 3114 against three clinically used antibiotics was investigated along with the phenotypic and genotypic alterations in the cell. It induced 8, 44 and 22-fold increase in resistance against colistin, ciprofloxacin and levofloxacin, respectively. Moreover, the biofilm formation of adapted culture was significantly enhanced due to a dense EPS around the cell (as revealed by SEM images). The structural changes in EPS were demonstrated by FTIR spectroscopy. The adequate growth of adapted MCC 3114 despite increased level of ROS indicates its persistence in copper and ROS stress. The physiological alterations in cell viz., increased efflux pump activity and decreased membrane permeability was observed. Molecular analysis revealed increased expression of efflux pump related genes, oxidative stress genes, integron and antibiotic resistance genes. In sum, our study revealed that the exposure of the critical pathogen, A. baunmannii to copper in hospital settings and environmental reservoirs can impose adaptive pressure which may lead to genotypic as well phenotypic changes in cell resulting into the augmentation of antibiotic resistance.</p>","PeriodicalId":491,"journal":{"name":"Biometals","volume":" ","pages":""},"PeriodicalIF":4.1,"publicationDate":"2024-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142871022","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}

Wild-type <i>D. melanogaster</i> flies were exposed to Cr(hist)₃ at concentrations of 5, 10, 15, and 20 µg/ml, and physiological parameters—including fecundity, fertility, developmental timelines, and antioxidant enzyme activity—were measured.

Developmental timelines were shortened, with larval and pupal periods reduced by 7.6% and 7.1%. Additionally, Cr(hist)₃ treatment led to a significant downregulation of lipid peroxidation (MDA) by 17.54% and upregulation in antioxidant enzymes (catalase, glutathione-S-transferase, and superoxide dismutase), indicating improved cellular defence against oxidative damage.
