Current status and strategies for controlling hexachlorobutadiene from multiple perspectives of emission, occurrence, and disposal.

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.

Nanobody-assisted nanoluciferase fragment complementation for in situ measurement and visualization of endogenous protein-protein interaction.

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.

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.

Promoting Photocatalytic Hydrogen Evolution by Stabilization of Excited Triplet States and Enhancement of Internal Electric Field at Dye/PCN Interface.

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.

HClO-Activated Near-Infrared Chemiluminescent Probes with a Malononitrile Group for In-Vivo Imaging.

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.

The ATAC complex represses the transcriptional program of the autophagy-lysosome pathway via its E3 ubiquitin ligase activity.

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.

Heat-Processed Diet Rich in Advanced Glycation End Products Induced the Onset and Progression of NAFLD via Disrupting Gut Homeostasis and Hepatic Lipid Metabolism.

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 .

Mendelian randomization reveals predictive, preventive, and personalized insights into inflammatory bowel disease: the role of gut microbiome and circulating inflammatory proteins.

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.

Case report: CD7-targeted autologous CAR-T therapy for the treatment of T-cell acute lymphoblastic leukemia undergoing allogeneic peripheral blood stem cell transplantation in the long-term follow-up.

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.
