Raw pork is prone to oxidation and rancidity as it contains a high level of unsaturated lipid molecules. Reliable biomarkers to benchmark pork freshness and their formation have not been systematically investigated. The results indicated that the peroxide values, TVB-N and rancid volatiles dramatically increased in pork during the storage period (4 °C, 0-9 d).

Hexachlorobutadiene (HCBD), as an emerging persistent organic pollutant, poses a pressing global environmental issue concerning its reduction and control. However, the lack of systematic studies on the sources and occurrence of HCBD hinders the development of effective disposal technologies. This study addresses HCBD prevention and treatment from multiple perspectives, including source emissions, environmental contamination distribution, and control technologies.

Here, we developed nanobody-assisted nanoluciferase fragment complementation for in situ measurement and visualization of endogenous protein-protein interaction (NanaPPI). When an interaction occurs, primary antibodies for two proteins bring the proximity of secondary nanobody-fused small/large fragment to reassemble into an intact NanoLuc variant, thus transforming interaction events to luminescent signals in situ with high sensitivity. Compared to proximity ligation assay, NanaPPI has a similar signal-to-background ratio, but it is more convenient with faster procedures, easier readout and lower cost.

Tumor whole-cell vaccines are designed to introduce a wide range of tumor-associated antigens into the body to counteract the immunosuppression caused by tumors. In cases of lymphoma of which the specific antigen is not yet determined, the tumor whole-cell vaccine offers distinct advantages. However, there is still a lack of research on an effective preparation method for the lymphoma whole-cell vaccine.

The heterojunction photocatalysts composed of organic dyes and polymeric carbon nitride (PCN) have great potential for photocatalytic hydrogen evolution (PHE). However, serious charge recombination exists at the dye/PCN interface for the large gaps in time scales and the poor driving force of charge transfer process. Herein, both the excited triplet states of organic dyes with long lifetimes and strong internal electric fields (IEF) as charge transfer driving forces are achieved by the construction of high dipole moments with aromatic-core engineering, and modulation of dye aggregates by alkyl modification.

Chemiluminescence (CL) imaging has emerged as a powerful approach to molecular imaging that allows exceptional sensitivity with virtually no background interference because of its unique capacity to emit photons without an external excitation source. Despite its high potential, the application of this nascent technique faces challenges because the current chemiluminescent agents have limited reactive sites, require complex synthesis, are insufficiently bright, and lack near-infrared emission. Herein, a series of HClO-activated chemiluminescent probes that exhibit robust near-infrared emission are studied.

Article Synopsis
  • The EPR effect helps nanodrugs target solid tumors, but variability in this effect has hindered clinical success, making its mechanisms important to study.
  • This study aimed to develop a method that combines radiogenomics and MRI to better understand how nanoparticles (NPs) penetrate tumors using a contrast agent made from PLGA-coated FeO NPs.
  • Through gene enrichment analyses, key genes influencing vascular permeability were identified, which can enhance the understanding of how NPs behave in tumor environments, ultimately supporting personalized treatment strategies.

Background: Neuropsychiatric disorders in systemic lupus erythematosus (NPSLE) are often accompanied by alterations in brain structure and function. Subtle changes in brain structure also can be observed in non-NPSLE patients. MRI can be used as a non-invasive tool to determine nervous system involvement in SLE.

The Ada two A-containing (ATAC) complex, containing histone acetyltransferases general control non-derepressible 5 (GCN5) or p300/CBP-associated factor (PCAF), has gained recognition as a prominent transcriptional coactivator. Recent revelations unveiled E3 ligase activity present in both GCN5 and PCAF; however, how the dual enzymatic activities of the ATAC complex orchestrate distinct transcriptional programs and signaling networks remains largely elusive. Our study unveils the function of the ATAC complex as a negative regulator of the autophagy-lysosome pathway's transcriptional program by modulating the stability of transcription factors TFE3 and TFEB.

Epidemiologic studies have suggested an association between the consumption of dietary advanced glycation end products (dAGEs) and the incidence of nonalcoholic fatty liver disease (NAFLD). However, the precise mechanism by which dAGEs induce NAFLD development, particularly the pathogenic role of the gut-liver axis, remains poorly understood. In this study, by establishing a high-AGE diet (HAD)-fed C57BL/6 mouse model, we employed multiomics approaches combined with a series of biological analyses to investigate the effect of HAD on NAFLD .

Background: A chronic illness with increasing global frequency, inflammatory bowel disease (IBD), which includes ulcerative colitis (UC) and Crohn's disease (CD), profoundly affects patients' quality of life and healthcare systems. IBD pathogenesis consists of changes in gut microbiota, immune system dysregulation, and genetic predisposition. Although emerging data suggests that gut microbiota and circulating inflammatory proteins play critical roles in IBD, their utility as biomarkers for predictive, preventive, and personalized medicine (PPPM) remains incompletely understood.

Introduction: Chimeric antigen receptor T-cell (CAR-T) therapy has emerged as a promising approach for treating relapsed/refractory (r/r) T-cell acute lymphoblastic leukemia (T-ALL). However, it is mostly used as a bridging therapy for allogeneic hematopoietic stem cell transplantation (allo-HSCT). Furthermore, secondary allo-HSCT is costly and associated with significantly high treatment-related mortality rate than the primary transplants.

  • Co-combustion of municipal solid waste (MSW) with industrial solid waste (ISW) is increasingly common, but its impact on harmful pollutants remains unclear, complicating control efforts.
  • An incineration study using a 650 t/d capacity tested various ISW blends and developed a new model to understand the relationship between waste components and their toxic byproducts, including PCDD/Fs and dl-PCBs.
  • Results showed co-combustion led to a significant increase in the generation of these contaminants, particularly from plastics like PET and PVC, indicating a need for stricter regulations on blending certain waste types to minimize toxic emissions.

Non-destructive handling such as wafer handling usually requires a high-temperature environment, however, most bionic materials fail in high temperatures due to material decomposition. In this study, inspired by the unique microstructure of locust toe pads with low adhesion and high friction, bionic high-temperature friction pads are designed and fabricated, selecting high-temperature-resistant silicone rubber as the material. The interfacial mechanical properties at high temperatures are analyzed.

  • Research on mRNA stability in wheat, a crucial crop, is limited, so we studied mRNA decay in durum wheat to understand its regulatory landscape.
  • Our findings show that the structure of the 3' UTR and preference for RNA motifs across subgenomes affect mRNA stability and abundance, creating an imbalance in decay among subgenomic RNAs.
  • Additionally, variations in RNA structural motifs due to domestication can lead to differences in mRNA stability and expression levels, highlighting the significance of RNA structure in gene regulation and potential crop improvement strategies.
