Drug-induced hyponatremia is an adverse reaction with accelerated electrolyte disturbance. This study reported a rare case of delayed hyponatremia in a 68year-old female with recurrent upper tract urothelial carcinoma after Gemcitabine plus Cisplatin (GC) and Tislelizumab treatment. She had left ureter surgery, recurrence a year later with mildly abnormal kidney function (glomerular filtration rate (GFR) was 54.

The clinical application of curcumin (CUR) is restricted by its low solubility, instability, and poor bioavailability. To overcome these limitations, we developed a novel stearic acid-grafted inulin-based nano-delivery system for CUR encapsulation. The structure of stearoyl inulin (SA-IN) was characterized using Fourier-transform infrared spectroscopy, hydrogen nuclear magnetic resonance, thermogravimetric analysis, and contact angle measurements.

A novel fluorescent probe, Bibc-DNBS, based on the combination of the PET (photoinduced electron transfer) and ESIPT (excited-state intramolecular proton transfer) mechanisms, was designed and synthesized. Bibc-DNBS exhibited a Stokes shift of 172 nm in the fluorescence detection field. In addition, the probe exhibited good performance in key parameters in bioassays such as sensitivity, specificity, and response time.

Hydroxychloroquine, used initially as an anti-malarial drug, is now recognized for its anti-tumor effects in a range of human cancers. Nevertheless, there has been limited attention given to the molecular mechanisms of anti-tumor action of hydroxychloroquine. Here, we investigated the anti-tumor effect of hydroxychloroquine in human A549 cells and further analyzed the potential molecular mechanisms involved.

The equilibrium state of hydrogen sulfide (HS), a gaseous signaling molecule produced by lysosomal metabolites, in vivo is crucial for cellular function. Abnormal fluctuations in HS concentration can interfere with the normal function of lysosomes, which has been closely linked to the pathogenesis of a variety of diseases. In view of this, a novel fluorescent probe based on 1,3,5-triarylpyrazolines was developed for the precise detection of HS in lysosomes by using the hydrophilic morpholine moiety as a lysosomal targeting unit, and 2,4-dinitroanisole as a fluorescence-quenching and HS-responsive unit.

Background: In prior research employing iTRAQ (Isobaric Tags for Relative and Absolute Quantitation) technology, we identified a range of proteins in breast cancer tissues exhibiting high levels of acetylation. Despite this advancement, the specific functions and implications of these acetylated proteins in the context of cancer biology have yet to be elucidated. This study aims to systematically investigate the functional roles of these acetylated proteins with the objective of identifying potential therapeutic targets within breast cancer pathophysiology.

The continuous decline of human semen quality during the past decades has drawn much concern globally. Previous studies have suggested a link between abnormal BMI and semen quality decline, but the results remain inconsistent. This systematic review and meta-analysis aimed to evaluate the association between body mass index (BMI) and semen quality.

Background: The short-term adverse effects of ambient fine particulate matter (PM) and ozone (O) on anxiety disorders (ADs) remained inconclusive.

Methods: We applied an individual-level time-stratified case-crossover study, which including 126,112 outpatient visits for ADs during 2019-2021 in Guangdong province, China, to investigate the association of short-term exposure to PM and O with outpatient visits for ADs, and estimate excess outpatient visits in South China. Daily residential air pollutant exposure assessments were performed by extracting grid data (spatial resolution: 1 km × 1 km) from validated datasets.

Article Synopsis
  • * The research included 2,001 patients from 10 hospitals who underwent various treatments; findings revealed that CM significantly improved overall survival compared to standard treatments, with median survival times of 18.17 months for the CM cohort versus 12.45 months for the non-CM cohort.
  • * Factors such as mixed tumor type, more than 6 cycles of first-line treatment, use of CM, palliative surgery, and specific medications were identified as independent predictors of better survival outcomes.

Immunotherapy has been developed, which harnesses and enhances the innate powers of the immune system to fight disease, particularly cancer. PD-1 (programmed death-1) and PD-L1 (programmed death ligand-1) are key components in the regulation of the immune system, particularly in the context of cancer immunotherapy. PD-1 and PD-L1 are regulated by PTMs, including phosphorylation, ubiquitination, deubiquitination, acetylation, palmitoylation and glycosylation.

Background: Risk factors for temporomandibular disorder (TMD) pain remain unclear.

Objectives: This study aimed to identify risk factors for TMD pain using a biopsychosocial model and to investigate interactions between potential risk factors-oral behaviours (OBs), psychological factors and sleep quality-and their direct and indirect effects on TMD pain.

Methods: This was a cross-sectional study of 488 patients with TMDs (422 women; 30.

Article Synopsis
  • Anti-tumor drugs often face challenges like side effects and ineffective delivery to tumors, reducing chemotherapy's effectiveness.
  • Researchers developed an innovative drug delivery system (MCN-SS-GQDs) using mesoporous carbon nanoparticles for better drug loading and graphene quantum dots for controlled release based on the tumor environment.
  • This system utilizes photothermal properties to increase local temperatures in tumors, promoting drug release and sensitivity of tumor cells to chemotherapy, while also ensuring deeper penetration into tumor tissues.

This study aims to investigate the role and molecular mechanism of anthocyanin in improving liver fibrosis through ferroptosis, providing a basis for drug development and targeted therapy. In this study, a mouse model of liver fibrosis was established using CCl, and the anthocyanin treatment groups were administered 100 mg/kg anthocyanin daily via gavage. Furthermore, real-time fluorescent quantitative PCR (qRT-PCR), Western blotting (WB), and enzyme-linked immunosorbent assay were used to assess liver fibrosis indicators and liver injury markers.

Although phenanthroline diamide ligands have been widely reported, their limited solubility in organic solvents and poor performance in the separation of trivalent actinides (An(III)) and lanthanides (Ln(III)) at high acidity are still clear demerits. In this study, we designed and synthesized three highly soluble phenanthroline diamide ligands with different side chains. By introducing alkyl chains and ester groups, the ligands solubility in 3-nitrotrifluorotoluene is increased to over 600 mmol/L, significantly higher than the previous reported phenanthroline diamide ligands.

Low-grade glioma (LGG) poses significant management challenges and has a dismal prognosis. While immunotherapy has shown significant promise in cancer treatment, its progress in glioma has confronted with challenges. In our study, we aimed to develop an immune-related gene prognostic index (IRGPI) which could be used to evaluate the response and efficacy of LGG patients with immunotherapy.

The association of ambient fine particulate matter (PM) exposure with cancer mortality was controversial, which may ascribe to the difference in PM constituents. Polycyclic aromatic hydrocarbons (PAHs) are carcinogenic constituents in PM, which are suspected to account for PM-induced cancer mortality but are yet to be investigated. We aimed to assess the association between long-term exposure to PM-bound PAHs and cancer mortality and estimate the attributable mortality.

Drug-induced liver injury (DILI), as a classic acute inflammation, has attracted widespread concern due to its unpredictability and severity. Among the various reactive oxygen species, HClO has been used as a marker for the detection of DILI process. Thus, we designed and synthesized a "turn-on" fluorescent probe FBC-DS by modifying 3'-formyl-4'-hydroxy-[1,1'-biphenyl]-4-carbonitrile (FBC-OH) with N, N-dimethylthiocarbamate group for sensitively sensing HClO.
