Evaluation of active substances in gamboge and their mechanisms for the treatment of colorectal cancer by UPLC-MS/MS integrated with network pharmacology.

Gamboge exhibits anti-colorectal cancer (CRC) activity, however, its active compounds and the underlying mechanisms remain unclear. Herein, a liquid chromatography tandem mass spectrometry (UPLC-MS/MS) method for determining gambogellic acid, β-morellic acid, isogambogenic acid, gambogenic acid, R-gambogic acid, S-gambogic acid, and hydroxygambogic acid in gamboge was established. The key parameters including ion transitions, voltages, LOD, and LOQ were determined, with LOD ranging from 0.

Optimizing the quality of emergency head CT imaging: An automated pipeline for correcting head image position.

Introduction: This study aims to evaluate the quality of head CT images in emergency radiology at a public hospital in China and to investigate whether the implementation of an automatic head CT image position correction pipeline can improve radiologists' reading efficiency and reduce the rate of missed skull base fractures.

Methods: A total of 15,560 distinct emergency head CT examinations performed between January 2019 and December 2020 at Nanjing Drum Tower Hospital were included in this study. All head CT scans were normalized to Montreal Neurological Institute (MNI) space and the orientation matrices were obtained.

Central SGLT2 mediate sympathoexcitation in hypertensive heart failure via attenuating subfornical organ endothelial cGAS ubiquitination to amplify neuroinflammation: Molecular mechanism behind sympatholytic effect of Empagliflozin.

Background: Sodium/glucose co-transporter 2 (SGLT2) inhibitors have transformed heart failure (HF) treatment, offering sympatholytic effects whose mechanisms are not fully understood. Our previous studies identified Cyclic GMP-AMP synthase (cGAS)-derived neuroinflammation in the Subfornical organ (SFO) as a promoter of sympathoexcitation, worsening myocardial remodeling in HF. This research explored the role of central SGLT2 in inducing endothelial cGAS-driven neuroinflammation in the SFO during HF and assessed the impact of SGLT2 inhibitors on this process.

The novel COVID-19 treatment VV116 is a potential inhibitor of Zika virus.

Zika virus (ZIKV) is a mosquito-borne, positive-stranded RNA virus, ZIKV infection during pregnancy threatens pregnancy and fetal health, and it remains a global health threat, there are no clinically approved vaccines or antiviral drugs for the treatment of ZIKV infection. VV116 is an oral drug candidate of nucleoside analog against SARS-CoV-2 that has demonstrated a satisfactory safety and tolerability in healthy subjects. Our study shows for the first time that VV116 has potent activity against ZIKV.

CC16 alleviates PM2.5-induced lung epithelial cell injury and airway inflammation in asthmatic mice by inhibiting ferroptosis.

Background: Exposure to PM2.5 represents a significant public health challenge, closely associated with the worsening of asthma, a condition that still lacks effective preventive measures. Club Cell 16 kDa protein (CC16), recognized for its anti-inflammatory and antioxidant properties, may serve a protective function in asthma exacerbated by PM2.

GRIM-19-mediated induction of mitochondrial STAT3 alleviates systemic sclerosis by inhibiting fibrosis and Th2/Th17 cells.

The gene associated with the retinoid-IFN-induced mortality-19 (GRIM-19) protein is a regulator of a cell death regulatory protein that inhibits STAT3, which is a critical transcription factor for interleukin (IL)-17-producing T (Th17) cells and a key integrator of extracellular matrix accumulation in systemic sclerosis (SSc). This protein is also a component of mitochondrial complex I, where it directly binds to STAT3 and recruits STAT3 to the mitochondria via the mitochondrial importer Tom20. In this study, the role of GRIM19 and its relationship with STAT3 in SSc development was investigated using a murine model of SSc.

Research on the dielectric properties of flexible β-CD/PVDF all-organic films.

All-organic dielectric polymers are currently a hot topic in the study of dielectric materials. However, it is still challenging to improve the dielectric constant, breakdown strength, and energy storage density of materials simultaneously. This study used PVDF as the matrix, and β-CD/PVDF all-organic composite dielectric films were prepared using a solution blending method.

PM exposure during pregnancy affects childhood asthma via placental epigenetic changes: Neuronal differentiation and proliferation and Notch signaling pathways.

Particulate matter (PM) exposure during pregnancy increases the risk of developing asthma in children. However, the placental mechanisms have yet to be elucidated. This study aims to evaluate the mechanisms associated with PM exposure during pregnancy and asthma susceptibility via placental epigenetic dysregulation.

SIRT5 mediated succinylation of SUCLA2 regulates TCA cycle dysfunction and mitochondrial damage in pancreatic acinar cells in acute pancreatitis.

Acute pancreatitis (AP) is a severe inflammatory disorder associated with metabolic reprogramming and mitochondrial dysfunction. This study investigated central carbon metabolism alterations in pancreatic acinar cells during AP, elucidated the molecular mechanisms of tricarboxylic acid (TCA) cycle disorders, and explored the role of protein hypersuccinylation in AP pathogenesis. Using in vitro and in vivo AP models, targeted metabolomics and bioinformatics analyses revealed TCA cycle dysregulation characterized by elevated succinyl-CoA and decreased succinate levels.

Ganoderma Lucidum polysaccharide peptide (GL-PP2): A potential therapeutic agent against sepsis-induced organ injury by modulating Nrf2/NF-κB pathways.

Sepsis, characterized by a severe immune response to infection, remains a leading cause of mortality, with few effective strategies to prevent organ damage. Targeting inflammation, oxidative stress, and apoptosis is crucial for improving outcomes and advancing sepsis management. We investigated the protective effects of Ganoderma Lucidum Polysaccharide Peptide 2 (GL-PP2) against sepsis-induced organ damage, focusing on immune regulation and kidney protection.

Boosting effect of ultrasonication on the oxygen evolution reaction during zinc electrowinning.

In this study, the electrochemical and anodic behaviors of Pb-Ag anodes during ultrasound-assisted zinc electrowinning were meticulously examined. The oxygen evolution reaction (OER) occurring at the Pb-Ag anodes in a 150 g L aqueous HSO solution was studied in the absence (silent) and presence of ultrasonication (40 kHz, 100 % acoustic amplitude). Electrochemical impedance spectroscopy (EIS), cyclic voltammetry (CV), linear sweep voltammetry (LSV), and zinc electrowinning tests were conducted to analyze the electrochemical behavior of the Pb-Ag anodes during zinc electrowinning.
