Fangchinoline eliminates intracellular Salmonella by enhancing lysosomal function via the AMPK-mTORC1-TFEB axis.

Introduction: Salmonella, a foodborne zoonotic pathogen, is a significant cause of morbidity and mortality in animals and humans globally. With the prevalence of multidrug-resistant strains, Salmonellosis has become a formidable challenge. Host-directed therapy (HDT) has recently emerged as a promising anti-infective approach for treating intracellular bacterial infections.

[Electroacupuncture improves pulmonary function by reducing inflammatory reaction via inhibiting miR-19b-3p to regulate SOCS3/JAK1/STAT3 signaling pathway in mice with chronic obstructive pulmonary disease].

Objectives: To explore whether electroacupuncture(EA) can increase the expression of suppressor of cytokine signaling (SOCS)3 by affecting the expression of miR-19b-3p, inhibiting the continuous activation of janus kinase (JAK)1 /signal transducer and activator of transcription (STAT)3 signaling pathway, and improve pulmonary inflammation in chronic obstructive pulmonary disease (COPD) mice.

Nontarget analysis (NTA) by liquid chromatography coupled to high-resolution mass spectrometry improves the capacity to comprehend the molecular composition of complex mixtures compared to targeted analysis techniques. However, the detection of unknown compounds means that quantification in NTA is challenging. This study proposes a new semi-quantitative methodology for use in the NTA of organic aerosol.

Inhibitory Effect of TCF7L2 on Pancreatic β-Cell Dedifferentiation via ERK/MAPK Signaling Pathway in Diabetes.

Background: Transcription factor 7-like 2 (TCF7L2) variants seem to affect diabetes susceptibility through β-cell dysfunction, underlying basis of which has been considered to be β-cell dedifferentiation rather than apoptotic β-cell death. The Extracellular regulated protein kinases/Mitogen-activated protein kinase signaling pathway (ERK/MAPK signaling pathway) has been confirmed to be significantly associated with multiple cellular process, including cellular dedifferentiation. However, the effects of TCF7L2 on β-cell function and ERK/MAPK signaling pathway are poorly understood.

Persistent organic pollutants exposure and risk of depression: A systematic review and meta-analysis.

Recently, more and more epidemiological studies have examined the impact of exposure to persistent organic pollutants (POPs) on depression, but the results are inconsistent. Thus, we conducted a systematic review and meta-analysis to better understand the effects of POPs exposure on the risk of depression in the general population. We searched PubMed, Embase, Web of Science, and Scopus databases for studies before March 20, 2024.

Bone morphogenetic protein 4 ameliorates bleomycin-induced pulmonary fibrosis in mice by repressing NLRP3 inflammasome activation and epithelial-mesenchymal transition.

Background: Idiopathic pulmonary fibrosis (IPF) is a progressive and deadly lung disease with limited therapeutic options. Bone morphogenetic protein 4 (BMP4), a multifunctional growth factor that belongs to the transforming growth factor-β superfamily, is able to relieve pulmonary fibrosis in mice; nevertheless, the potential mechanism of action remains largely unknown. Growing evidence supports the notion that reiterant damage to the alveolar epithelial cells (AECs) is usually the "prime mover" for pulmonary fibrosis.

Simultaneous quantification of baloxavir marboxil and its active metabolite in human plasma using UHPLC-MS/MS: Application to a human pharmacokinetic study with different anticoagulants.

Baloxavir marboxil (BXM) is a cap-dependent nucleic acid endonuclease inhibitor, which exerts its antiviral effects after being metabolized to its active form baloxavir acid (BXA). Ethylenediamine tetra-acetic acid (EDTA) and heparin are the two most used anticoagulants in clinical blood sample collection to estimate drug levels in plasma. However, compared to heparin plasma, there is a lack of clinical pharmacokinetic data of BXA using EDTA anticoagulant tubes for blood collection.

Molecular Identification of the Glutaredoxin 5 Gene That Plays Important Roles in Antioxidant Defense in (Fallou).

Glutaredoxin (Grx) is a group of redox enzymes that control reactive oxygen species (ROS), traditionally defined as redox regulators. Recent research suggested that members of the family may be involved in more biological processes than previously thought. Therefore, we cloned the gene and identified its role in diapause.

Cyclometalated iridium(III) tetrazine complexes for mitochondria-targeted two-photon photodynamic therapy.

The fast-moving field of photodynamic therapy (PDT) has provided fresh opportunities to expand the potential of metallodrugs to combat cancers in a light-controlled manner. As such, in the present study, a series of cyclometalated Ir(III) complexes modified with a tetrazine functional group (namely, Ir-ppy-Tz, Ir-pbt-Tz, and Ir-dfppy-Tz) are developed as potential two-photon photodynamic anticancer agents. These complexes target mitochondria but exhibit low toxicity towards HLF primary lung fibroblast normal cells in the dark.

LDHA contributes to nicotine induced cardiac fibrosis through autophagy flux impairment.

Cardiac fibrosis is a typical feature of cardiac pathological remodeling, which is associated with adverse clinical outcomes and has no effective therapy. Nicotine is an important risk factor for cardiac fibrosis, yet its underlying molecular mechanism remains poorly understood. This study aimed to identify its potential molecular mechanism in nicotine-induced cardiac fibrosis.

Computerized analysis of haptens for the ultrasensitive and specific detection of Pyriftalid.

Pyriftalid (Pyr) is one of the most commonly used herbicides and due to its widespread and improper use, it has led to serious pollution of groundwater, soil and other ecosystems, threatening human health. A rapid method to detect Pyr was urgently needed. A high specific monoclonal antibody (mAb) against Pyr with IC50 values of 4.

Multiple factors and features dictate the selective production of ct-siRNA in Arabidopsis.

Coding transcript-derived siRNAs (ct-siRNAs) produced from specific endogenous loci can suppress the translation of their source genes to balance plant growth and stress response. In this study, we generated Arabidopsis mutants with deficiencies in RNA decay and/or post-transcriptional gene silencing (PTGS) pathways and performed comparative sRNA-seq analysis, revealing that multiple RNA decay and PTGS factors impede the ct-siRNA selective production. Genes that produce ct-siRNAs often show increased or unchanged expression and typically have higher GC content in sequence composition.

Simulated nitrogen load promoted mineralization of N2P1 compounds and accumulation of N4S2 compounds in soil dissolved organic matter in a typical subtropical estuarine marsh.

Soil dissolved organic matter (DOM) is the most reactive pool in estuarine marshes, playing an important role in the biogeochemical processes of biogenetic elements. To investigate the impacts of enhanced nitrogen (N) load on DOM molecular composition and its interactions with microbes in typical Cyperus malaccensis mashes of the Min River estuary, a field N load experiment with four N levels (0, 37.50, 50 and 100 g exogenous N m yr, respectively; applied monthly for a total of seven months) was performed.
