摘要:
Geographical discrimination and adulteration analysis play significant roles in edible oil analysis. A novel method for discrimination and adulteration analysis of edible oils were proposed in this study. The two-dimensional correlation spectra of edible oils were obtained by solvents perturbation and the convolutional neural networks (CNNs) were constructed to analyze the synchronous and asynchronous correlation spectra of the edible oils. The differences for geographical origins of oils or oil types could be amplificated through the networks. For different networks, the layer sequences and the filter number of convolutional layers may affect the analysis results. A group of sesame oils from different geographical origins and a group of olive oils adulterated by other vegetable oils were adopted to evaluate the proposed method. The results show that the proposed method may provide an alternative method for edible oil discrimination and adulteration analysis in practical applications. For the two datasets, the prediction accuracy could be 97.3% and 88.5%, respectively. (C) 2020 Elsevier B.V. All rights reserved.

摘要:
A variety of mycotoxins from different sources frequently contaminate farm products, presenting a potential toxicological concern for animals and human. Mycotoxin exposure has been the focus of attention for governments around the world. To date, biomarkers are used to monitor mycotoxin exposure and promote new understanding of their role in chronic diseases. The goal of this research was to develop and validate a sensitive UHPLC-MS/MS method using isotopically-labeled internal standards suitable for accurate determination of 18 mycotoxin biomarkers, including fumonisins, ochratoxins, Alternaria and emerging Fusarium mycotoxins (fumonisin B1, B2, and B3, hydrolyzed fumonisin B1 and B2, ochratoxin A, B, and alpha, alternariol, alternariol monomethyl ether, altenuene, tentoxin, tenuazonic acid, beauvericin, enniatin A, A1, B, and B1) in human urine. After enzymatic digestion with β-glucuronidase, human urine samples were cleaned up using HLB solid phase extraction cartridges prior to instrument analysis. The multi-mycotoxin and analyte-specific method was validated in-house, providing satisfactory results. The method provided good linearity in the tested concentration range (from LOQ up to 25–500 ng/mL for different analytes), with R2 from 0.997 to 0.999. The limits of quantitation varied from 0.0002 to 0.5 ng/mL for all analytes in urine. The recoveries for spiked samples were between 74.0% and 133%, with intra-day precision of 0.5%–8.7% and inter-day precision of 2.4%–13.4%. This method was applied to 60 urine samples collected from healthy volunteers in Beijing, and 10 biomarkers were found. At least one biomarker was found in all but one of the samples. The high sensitivity and accuracy of this method make it practical for human biomonitoring and mycotoxin exposure assessment. © 2020 by the authors.

摘要:
Deoxynivalenol (DON), along with 3-acetyl-deoxynivalenol (3-ADON) and 15-acetyl-deoxynivalenol (15-ADON), occur in grains and cereal products and is often hazardous to humans and livestock. In this study, 579 wheat samples and 606 maize samples intended for consumption were collected from China in 2017 and analyzed to determine the co-occurrence of type-B trichothecenes (DON, 3-ADON, and 15-ADON). All the wheat samples tested positive for DON, while 99.83% of the maize samples were DON-positive with mean DON concentrations of 165.87 and 175.30 µg/kg, respectively. Per the Chinese standard limits for DON, 3.63% of wheat and 2.97% of the maize samples were above the maximum limit of 1000 µg/kg. The DON derivatives (3-ADON and 15-ADON) were less frequently found and were present at lower levels than DON in wheat. 3-ADON and 15-ADON had incidences of 13.53% and 76.40%, respectively, in maize. By analyzing the distribution ratio of DON and its derivatives in wheat and maize, DON (95.51%) was the predominant toxin detected in wheat samples, followed by 3.97% for the combination of DON + 3-ADON, while DON + 3-ADON + 15-ADON and DON + 15-ADON were only found in 0.17% and 0.35% of wheat samples, respectively. Additionally, a large amount of the maize samples were contaminated with DON + 15-ADON (64.19%) and DON (22.11%). The samples with a combination of DON + 3-ADON and DON + 3-ADON + 15-ADON accounted for 1.32% and 12.21%, respectively. Only one maize sample did not contain all three mycotoxins. Our study shows the necessity of raising awareness of the co-occurrence of mycotoxin contamination in grains from China to protect consumers from the risk of exposure to DON and its derivatives. © 2020 by the authors.

摘要:
Nepsilon-(carboxymethyl)lysine (CML) is a potentially noxious compound that is causing widespread concern due to its use in various food products. In this study, we investigated CML neurotoxicity via an in vivo experiment with mice, and an in vitro experiment using a 3D microvascular network model (with human brain vascular endothelial cell and human astrocyte) that simulated the blood-brain barrier. We found that CML could induce cell survival status variations, and histopathological changes to the brain. In addition, CML increased levels of oxidative stress, prompted the protein expression of the receptor for advanced glycation end-products (RAGE). CML up-regulated both the gene expression of RAGE, the activating protein-1 (AP-1), the inflammatory cytokines Interleukin-6 (IL-6), vascular cell adhesion molecule1 (VCAM-1), monocyte chemotactic protein1 (MCP-1). We, therefore, postulated that CML has the potential to deleteriously affect the nervous system through oxidative stress and that activation of the p38 MAPK-AP-1 signaling pathway might be implicated in this pathological process.

摘要:
BACKGROUND: Sesamin and sesamolin are two typical and important lignans isolated from sesame oil. Various studies have shown the bioactivity, physiological activity, and potential health benefits of the two components. In this study, a rapid method for the simultaneous determination of sesamin and sesamolin in sesame oils was proposed. The excitation-emission fluorescence spectra of the oils were obtained after a simple pretreatment, then self-weighted alternating trilinear decomposition was used to extract the quantitative information from the very overlapping spectra. RESULTS: It was found that reasonable quantification results could be obtained with the limits of detection for the two lignans. These limits were 0.05 mg/g and 0.24 mg/g, and the limits of quantitation were 0.14 mg/g and 0.74 mg/g, respectively. The average recoveries for sesamin and sesamolin were 99.05% and 94.97%. CONCLUSION: The results indicate that, with simple sample pretreatment, the application for combining excitation-emission fluorescence spectra and self-weighted alternating trilinear decomposition can be a useful and sensitive tool for the determination of lignans in sesame oil. © 2020 Society of Chemical Industry. © 2020 Society of Chemical Industry

摘要:
This paper described an improved method for high-throughput and sensitive determination of zearalenone and its five metabolites (zearalanone, α-zearalenol, β-zearalenol, α-zearalanol and β-zearalanol) in human serum. Serum samples were measured both before and after enzyme hydrolysis to assess the free and total amount of each compound by ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) in multi reaction monitoring (MRM) mode following off-line 96-well μElution solid-phase extraction (SPE). All the analytes were completely separated on a C18 column within 6 min. It enabled multi-sample preparation at the same time eliminating tedious evaporation and reconstitution steps, allowing 96 (one plate) samples to be processed and analyzed within 24 h. Using an isotope labelled internal standard ( 13 C-ZEN), high recoveries were achieved for all the compounds in the range 91.6%-119.5%, with intra-day and inter-day relative standard deviations (RSDs) of less than 8%. The limits of detection (LOD) and the limits of quantification (LOQ) were 0.02-0.06 ng mL -1 (0.6-2 fmol) and 0.1-0.2 ng mL -1 (3-6 fmol), respectively, demonstrating a notable enhancement in sensitivity compared to the existing methods. The validated method was applied to the analysis of paired urine and serum samples collected from 125 healthy individuals in Henan Province, locating in the middle area of China. ZEN metabolites in human serum were significantly lower than those in urine. Only one serum sample was positive for ZEN after enzyme digestion, whereas at least one of ZEN biomarkers was detected in 75.2% of the paired urine samples. Some comparison and discussion were also included in this paper. © 2019 by the authors.

摘要:
A 3D functional human microvascular network in a microfluidic device was developed in this study. The established model enables endotheilal cells to form vessel-like microtissues and behave physiological functions which are closer to cells in human blood vessels. It provides a possible bridge for how the research outcomes translate to humans. The ɑ-MnO2 nanowires, which were successfully synthesized using the hydrothermal approach. The vascular toxicity was evaluated based on this organotypic 3D microvessel model. Our results demonstrated that ɑ-MnO2 nanowires can induce cytotoxicity in dose-dependently. Because the accumulation of reactive oxygen species (ROS) and depletion of glutathione (GSH) are observed in the nanowire-treated cells. In addition, intravascular accumulation of ɑ-MnO2 nanowires could induce endothelial dysfunction by oxidative stress. This is expressed in disorder of NO expression and IL-6 up-regulation. Based on these results, we concluded that a mechanism for ɑ-MnO2 nanowire-induced vascular toxicity, which involves the accumulation of ROS, up-regulation of oxidative stress and inflammatory factors. This investigation may provide a fundamental insight to understand the nanotoxicity of wire-shaped nanomaterials. © 2019, © 2019 Taylor & Francis Group, LLC.

摘要:
Folic acid is a necessary micronutrient for normal human growth and development. Benzo(a)pyrene (BaP) is a ubiquitously distributed environmental pollutant and its metabolite, benzo(a)pyrene-diol-epoxide, is known to exert a strong teratogenic and carcinogenic effect on the body’s tissues and cells. The aim of this study was to investigate the mechanism by which folic acid can inhibit the toxic effects of BaP both in vivo and in vitro. We measured changes in 16HBE cell activity affected by the intervention of folic acid on BaP using the cell counting kit-8 assay and that of cell cycle distribution by flow cytometry. At the same time, we assessed the xeroderma pigmentosum group A, xeroderma pigmentosum group C, excision repair cross complementation group 1, cyclinD1, and CKD4 mRNAs, and their related protein expression both in mouse lung tissue and in 16HBE cells. In conclusion, the mechanisms by which this effect is mediated were not entirely elucidated by our study, possibly because folic acid antagonizes the toxic effects of BaP by upregulating the levels of excision repair cross complementation group 1, xeroderma pigmentosum group A, and xeroderma pigmentosum group C gene expression to improve the rate of DNA repair, in turn accelerating the speed of repair for DNA damage caused by BaP. Meanwhile, folic acid could restrain BaP-induced cyclinD1 protein expression, which could help cells return to their normal cell cycle.

摘要:
羧甲基赖氨酸(CML)是食品加工中经美拉德反应由蛋白质与糖类通过非酶催化反应产生的一种晚期糖基化终末产物,是一种新型食品潜在有害物质。本文通过研究外源游离性CML对秀丽隐杆线虫寿命、子代数量、热环境中线虫存活时间的影响,探讨其可能的毒性机制。结果表明,外源游离性CML导致线虫产卵期缩短,寿命试验以及热刺激下存活的线虫数量呈现出剂量-反应关系。影响了TOR信号通路的Skn-1基因和生殖系统信号通路中的hsf-1基因,提高线虫的热环境阻力的抵抗力并延长其寿命。高浓度的CML降低了线虫的中DAF-16的表达水平从而影响其寿命,抑制线虫体内Folt-1基因的表达,从而减少其子代线虫的数量。

摘要:
Nε-(carboxymethyl)lysine (CML), which is a compound produced when food is processed, has aroused concern in recent years because of its potentially dangerous effects. This study aimed to investigate the mechanism of free CML-induced toxic injury in mice. The inflammatory cytokine tumor necrosis factor-α, transforming growth factor-β, vascular cell adhesion molecule-1 mRNA expression levels of CML-infected mice liver and kidney tissues significantly increased. While CML receptor—receptor for advanced glycation end products (RAGE) protein expression in male mice liver tissue had a more significant change than the control group, there was no significant difference in other dose groups compared with the control group. In conclusion, the foodborne free CML can be induced by oxidative stress and immune response to liver and kidney tissue injury in mice. Additionally, the free CML may also bind to RAGE, which activates the downstream inflammatory pathway. © 2019 Wiley Periodicals, Inc.

摘要:
采用响应面法优化水浸法削减镉污染的大米粉中镉的工艺条件,在最优条件下测定水浸法对大米粉营养成分的影响,并用扫描电镜、差示扫描量热仪、X射线衍射、红外光谱等方法分别研究水浸法对大米粉形态、热力学特征、淀粉晶体结构及官能团的影响。结果表明:水浸法削减大米粉中镉的最佳条件为水浸温度42℃、料液比1∶3(g/m L)、水浸时间47 h,此时镉含量为(0.459±0.006)mg/kg,大米粉中的镉去除率达到(61.75±4.31)%,处理后大米粉中镉含量为(0.176±0.003)mg/kg。在最佳工艺条件下,大米粉中的蛋白质含量显著降低(P<0.05),脂肪、淀粉、灰分也略有下降(P<0.05)。大米粉水浸后糊化起始温度降低,而峰值温度变化很小,说明大米粉晶体片层被破坏,稳定性降低,大米粉中直链淀粉含量可能升高,但水浸处理并没有破坏米粉内淀粉粒晶体成分。水浸大米粉面间距有略微的降低,说明水浸可能导致大米粉产品较原料产品的硬度、咀嚼度、回弹性、黏聚性下降。大米粉在水浸过程中并没有产生新的化学键或基团。

摘要:
目的:本研究旨在探讨氯化镉和镉污染大米中镉在体内吸收和分布的差异,为阐明大米中镉可能存在的健康风险提供依据。方法:采用SD大鼠模型,研究镉在镉污染大米和氯化镉(CdCl2)中的代谢、吸收和分布。研究比较了Cd~(2+)和大米中Cd的积累情况。结果:CdCl2组和Cd大米组的大鼠分别单次灌胃氯化镉和镉污染大米浑浊悬液(Cd的摄入量均为10μg/kg bw),CdCl2组和Cd大米组的大鼠血液中Cd浓度在2 h达到最高值,16 h后下降到与空白对照组相同的浓度。经过21天的持续灌胃后,每组动物的血、心、脾、肺中Cd含量无明显差异。与对照组相比,镉大米组大鼠肝脏和肾脏中镉的累积量显著增加118.78%和192.90%。与CdCl2组相比,Cd大米组大鼠肝脏和肾脏的Cd含量分别比CdCl2组高31.69%和42.91%。结论:CdCl2组与Cd大米组的大鼠血液中Cd代谢规律基本一致。低剂量Cd摄入21 d后,Cd在水稻中主要积聚在实验大鼠的肾脏和肝脏中,而在血液、心脏、脾脏和肺中仅略有积聚。大米中福在大鼠体内的累积量大于无机镉(CdCl2)。

摘要:
3-Monochloropropane-1,2-diol (3-MCPD) is a common food processing contaminant and a simple, rapid, sensitive and low cost monitoring technology is needed due to its potential carcinogenic nature. Carbon dots directly intercepted on filter paper provide high fluorescence intensity and can be adapted for use as a sensor. We synthesized a carbon dot-filter paper in combination with a molecularly imprinted polymeric film to extract 3-MCPD from samples. This grafted paper-based sensor exhibited a high adsorption capacity (68.97mgg(-1)), an excellent selectivity (imprinting factor=4.5) and a low detection limit (0.6ngmL(-1)). Recoveries ranged from 97.2% to 105.3% with relative standard deviations <5.6%. The results obtained using this method were linearly correlated to those of the classic GC-MS method (r=0.998). Based on the Chinese National Standard, this study provides a novel and powerful platform for the simple, rapid, sensitive and on-site analysis of 3-MCPD in soy sauce.

摘要:
Background: A growing body of evidence shows that indoor concentrations of airborne particles are often higher than is typically encountered outdoors. Since exposure to indoor PM2.5 is thought to be associated with cardiovascular disease, the health impacts of indoor air pollution need to be explored. Based on animal models, ambient particulate matter has been proved to promote coagulation which is very likely involved in the pathogenic development of cardiovascular disease. However, animal models are insufficient to predict what will happen with any certainty in humans. For this reason, the precise pathogenic mechanisms behind the development of cardiovascular disease in humans have not yet been determined. Results: We generated a 3D functional human microvascular network in a microfluidic device. This model enables human vascular endothelial cells to form tissue-like microvessels that behave very similarly to human blood vessels. The perfusable microvasculature allows the delivery of particles introduced into these generated human-like microvessels to follow the fluid flow. This exposure path effectively simulates the dynamic movement of airborne nanoscale particles (ANPs) within human vessels. In this study, we first identified the existence of ANPs in indoor air pollution. We then showed that ANPs could activate endothelial cells via ROS induced inflammation, and further resulted in abnormal expression of the coagulation factors (TF, TM and t-PA) involved in coagulation cascades. In addition, we found that a protein could cover ANPs, and this biointeraction could interfere with heparan sulfate (HS). Human organotypic 3D microvessel models provide a bridge for how research outcomes can translate to humans. Conclusions: The 3D human microvessel model was used to determine the physiological responses of human vessels to ANP stimulation. Based on the obtained data, we concluded that ANPs not only disrupts normal coagulation functions, but also act directly on anticoagulant factors in human vessels. These experimental observations provide a potential biological explanation for the epidemiologically established link between ANPs and coagulation abnormality. This organ-on-chip model may provide a bridge from in vitro results to human responses. © 2019 The Author(s).
