Therefore, it is imperative to develop precise and rapid methods to detect TBHQ in food products. In this study, Fe- and Mn-doped Prussian blue analogs (FeMn-PBAs) were prepared by co-precipitation, FeMn-PBAs/PAN was prepared by electrostatic spinning, and a novel FeMn@C/CNFs composite was prepared by carbonization in nitrogen.

Macrophage membrane enveloped on double-locked nanoplatform with right-side-out orientation to improving precise theranostic for atherosclerosis.

A right-side-out orientated self-assembly of cell membrane-camouflaged theranostic nanoplatform is crucial for ensuring their biological functionality inherited from the source cells. However, the low specificity and fluorescence background interference hampered reliable assessment of lipids content in plaques. In this work, a spontaneous right-side-out coupling-driven ROS-responsive theranostic nanoplatform has been developed to enhance accumulation within atherosclerotic plaques, target lipids imaging in plaques, reduce the interference from background fluorescence and inhibit the progression of atherosclerosis (AS).

Effect of frozen storage on the untargeted and targeted metabolites of flavored roasted beef using UHPLC-MS/MS and GC-MS.

In this study, we investigated the changes in untargeted metabolites using UHPLC-MS/MS and the flavors of nonflavored (BS1) and flavored (BS2) roasted beef using GC-MS throughout a 6-month frozen period. A total of 509, 659, and 496 metabolites met the conditions for differential screening, and 56, 103, and 47 differential metabolites were recognized between BS1 and BS2 at 0, 3, and 6 months of frozen periods, respectively. The total relative abundance of organic nitrogen compounds, phenylpropanoids, polyketides, organic acids and their derivatives, and benzenoids increased during frozen storage at 3 months and then decreased at 6 months.

Currently, there is a lack of comprehensive research analyzing the changes in taste and volatile compounds that occur during the processing of beer fish. Thus, this study used HS-GC-IMS, electronic tongue, and electronic nose to investigate the changes in flavor components during various processing stages of beer fish.

Reactive oxygen species-responsive nano-platform with dual-targeting and fluorescent lipid-specific imaging capabilities for the management of atherosclerotic plaques.

Atherosclerosis (AS), a pathological cause of cardiovascular disease, results from endothelial injury, local progressive inflammation, and excessive lipid accumulation. AS plaques rich in foam cells are prone to rupture and form thrombus, which can cause life-threatening complications. Therefore, the assessment of atherosclerotic plaque vulnerability and early intervention are crucial in reducing the mortality rates associated with cardiovascular disease.

Detection of Naturally occurring abortive transcripts by Base-Stacking Hybridization Assisted Ligation and PCR amplification.

Abortive transcripts (ATs) refer to nascent 2-10 nucleotides (nt) RNAs released by RNA polymerases before synthesizing productive RNAs. The quantitative detection of ATs is important for studying transcription initiation and the biological function of ATs; however, no method is available for the qualitative and quantitative assessment of such ultra-short oligonucleotides (typically shorter than 11 nt) in vivo at present, even with the LNA probes, the detection limit can only reach 11 nt. Here, we demonstrated the base stacking hybridization assisted ligation (BSHAL) technique, combined with TaqMan-MGB qPCR, can detect 4-10 nt ATs with a specificity of nucleotide resolution and a sensitivity of approximately 10 pM.

Effect of different sweeteners on the quality, fatty acid and volatile flavor compounds of braised pork.

This study aimed to assess how several sweeteners (white sugar, fruit, mogrosides, and stevia glycoside) affected the flavor, fatty acid composition, and quality of braised pork. The findings indicated that braised meat prepared with sweeteners differed from typical braised pork. When simmered for 60 min, the typical braised pork with white granulated sugar exhibited a significant cooking loss (CL) and little water content.

Selection and Validation of Reference Genes for Gene Expression Studies in Codonopsis pilosula Based on Transcriptome Sequence Data.

Relative gene expression analyses by RT-qPCR (reverse transcription-quantitative PCR) are highly dependent on the reference genes in normalizing the expression data of target genes. Therefore, inappropriate endogenous control genes will lead to inaccurate target gene expression profiles, and the selection and validation of suitable internal reference genes becomes essential. In this study, we retrieved the commonly used reference genes in transcriptome datasets of Codonopsis pilosula by RNA-Seq (unpublished data), and selected 15 candidate reference genes according to the coefficient of variation (CV) and fold change (FC) value of gene expression.

Pollution characteristics and health risk assessment of volatile organic compounds emitted from different plastic solid waste recycling workshops.

The pollution profiles of volatile organic compounds (VOCs) emitted from different recycling workshops processing different types of plastic solid waste (PSW) and their health risks were investigated. A total of 64 VOCs including alkanes, alkenes, monoaromatics, oxygenated VOCs (OVOCs), chlorinated VOCs (ClVOCs) and acrylonitrile during the melting extrusion procedure were identified and quantified. The highest concentration of total VOCs (TVOC) occurred in the poly(acrylonitrile-butadiene styrene) (ABS) recycling workshop, followed by the polystyrene (PS), polypropylene (PP), polyamide (PA), polyvinyl chloride (PVC), polyethylene (PE) and polycarbonate (PC) workshops.

Pollution profiles and health risk assessment of VOCs emitted during e-waste dismantling processes associated with different dismantling methods.

Pollution profiles of typical volatile organic compounds (VOCs) emitted during dismantling of various printed circuit board assemblies (PCBAs) of e-wastes using different methods were comparatively investigated in the real e-waste dismantling workshops in South China in April 2013. Similar pollution profiles and concentrations of VOCs were observed between dismantling mobile phone and hard disk PCBAs by using electric blowers and between dismantling television and power supplier PCBAs using electric heating furnaces. Aromatic hydrocarbons (accounting for >60% of the sum of VOCs) were the dominant group during using electric blowers, while aromatic (accounting for >44% of the sum of VOCs) and halogenated hydrocarbons (accounting for >48% of the sum of VOCs) were the two dominant groups which contributed equally using electric heating furnaces.

Adsorption and degradation of model volatile organic compounds by a combined titania-montmorillonite-silica photocatalyst.
