[Simultaneous Removal of Antibiotic-resistant Bacteria, Genes, and Inhibition of Horizontal Transfer using Vis-rGO-CNCF-enhanced Peroxymonosulfate Activation Process].

As emerging contaminants, antibiotic-resistant bacteria （ARBs） and antibiotic-resistant genes （ARGs） pose a serious threat to human health and ecological security. Here, a reduced graphene oxide and g-CN co-doped copper ferrite （rGO-CNCF） were synthesized. The composite material was characterized using XRD, FTIR, XPS, SEM-EDS, TEM, and DRS analysis methods, and a visible-light-assisted rGO-CNCF-activated PMS system was constructed for the removal of ARB and ARGs in water.

Novel ligustilide derivatives target quorum sensing system LasR/LasB and relieve inflammatory response against Pseudomonas aeruginosa infection.

The increasing antibiotic resistance driven by Pseudomonas aeruginosa typically leads to uncontrolled and persistent inflammatory damage, which is primarily attributed to the virulence and biofilms produced by the bacteria. Herein, we present a novel anti-infective drug strategy designed to inhibit the bacterial quorum sensing system, thereby attenuating P. aeruginosa virulence, and modulating inflammation from drug-resistant bacterial infections.

Design, synthesis and biological evaluation of novel 3-hydroxypyridin-4(1H)-ones based hybrids as Pseudomonas aeruginosa biofilm inhibitors.

Pseudomonas aeruginosa (P. aeruginosa) is a gram-negative pathogenic bacterium, often causative drug-resistance related human infections, given its great capacity to form bioflm. It uses three major quorum sensing (QS) systems, las, rhl, and pqs, to regulate the expression of genes related to virulence and biofilm formation.

Tiliroside induces ferroptosis to repress the development of triple-negative breast cancer cells.

Ferroptosis is a newly found form of non-apoptotic regulated cell death that is essential for the advancement of cancer. Tiliroside (Til), an effective natural flavonoid glycoside of oriental paperbush flower, has been explored as a potential anticancer agent in a few cancer types. However, it is unclear whether and how Til could promote the death of triple-negative breast cancer (TNBC) cells by inducing ferroptosis.

Occurrence and ecological risk assessment of 16 phthalates in surface water of the mainstream of the Yangtze River, China.

New Insight into CO Reduction to Formate by In Situ Hydrogen Produced from Hydrothermal Reactions with Iron.

To reveal the nature of CO reduction to formate with high efficiency by in situ hydrogen produced from hydrothermal reactions with iron, DFT calculations were used. A reaction pathway was proposed in which the formate was produced through the key intermediate species, namely iron hydride, produced in situ in the process of hydrogen gas production. In the in situ hydrogenation of CO, the charge of H in the iron hydride was -0.

Parthenolide Augments the Chemosensitivity of Non-small-Cell Lung Cancer to Cisplatin the PI3K/AKT Signaling Pathway.

The mortality rate of non-small-cell lung cancer (NSCLC) remains high worldwide. Although cisplatin-based chemotherapy may greatly enhance patient prognosis, chemotherapy resistance remains an obstacle to curing patients with NSCLC. Therefore, overcoming drug resistance is the main route to successful treatment, and combinatorial strategies may have considerable clinical value in this effort.

Direct Targeting of CREB1 with Imperatorin Inhibits TGF2-ERK Signaling to Suppress Esophageal Cancer Metastasis.

Metastasis accounts for 90% of cancer death worldwide, and effective therapeutic strategies are lacking. The aim of this work is to identify the key drivers in tumor metastasis and screen therapeutics for treatment of esophageal squamous cell carcinoma (ESCC). Gene Ontology analysis of The Cancer Genome Atlas (TCGA) gene expression datasets of ESCC patients with or without lympy metastasis identifies that TGF2 is highly enriched in the pathways essential for tumor metastasis and upregulates in the metastatic ESCC tumors.

IGF2 induces CD133 expression in esophageal cancer cells to promote cancer stemness.

Failure to eradicate cancer stem cells (CSC) during primary therapy may lead to cancer recurrence. We recently reported that CD133 is a functional biomarker for CSCs in esophageal squamous cell carcinoma (ESCC) but the molecular pathways critical for maintenance of CD133-positive CSCs are largely unknown. Here, we revealed that knockdown of IGF2 or treatment with PI3K/AKT inhibitors markedly inhibited the abilities of CD133-positive ESCC cells to self-renew, resist chemotherapeutic drugs, and form tumors.
