Enhanced bacteriostatic effects of phage vB_C4 and cell wall-targeting antibiotic combinations against drug-resistant .

is a vital zoonotic pathogen known for its extensive drug resistance and ability to form biofilms, which contribute to its antibiotic resistance. In this study, the phage vB_C4, specifically targeting , was isolated and subjected to bioinformatic analysis and bacteriostatic activity assays. The combination of phage vB_C4 with antibiotics such as cephalothin and cefoxitin, which target the bacterial cell wall, resulted in a significantly enhanced bacteriostatic effect compared to either the phage or antibiotics alone.

Cooperative and Independent Functionality of tmRNA and SmpB in : A Multifunctional Exploration Beyond Ribosome Rescue.

The trans-translation system, mediated by transfer-messenger RNA (tmRNA, encoded by the gene) and its partner protein SmpB, helps to release ribosomes stalled on defective mRNA and targets incomplete protein products for hydrolysis. Knocking out the and genes in various pathogens leads to different phenotypic changes, indicating that they have both cooperative and independent functionalities. This study aimed to clarify the functional relationships between tmRNA and SmpB in a pathogen that poses threats in aquaculture and human health.

Ordered Photoexfoliation for Polypseudorotaxane Nanosheets.

Two-dimensional layered structural materials exhibit a wide range of properties due to their ultrahigh specific surface area. However, achieving ordered exfoliation to obtain uniform two-dimensional structures remains challenging. In this study, we developed a supramolecular system by covalently bonding hexathiobenzene (HB) into β-cyclodextrin to create a light-responsive moiety, followed by coassembly with bipyridine and nickel ions to form a polypseudorotaxane (PR) system, which enables an light-induced exfoliation strategy for two-dimensional materials.

Coordination Equilibrium-Assisted Coprecipitation Synthesis of Atomically Dispersed 3d Metal Catalysts.

As a frontier of heterogeneous catalysis, single-atom catalysts (SACs) have been extensively studied fundamentally. One obstacle that limits the industrial application of SACs is the lack of a synthetic method that can prepare the catalysts on a large scale. Wet-chemistry methods that are conventionally used to prepare nanoparticle-based industrial catalysts might be a solution.

Recombinant dsAAV9-mediated Endogenous Overexpression of Macrophage Migration Inhibitory Factor Alleviates Myocardial Ischemia-Reperfusion Injury via Activating AMPK and ERK1/2 Signaling Pathways.

Purpose: To investigate the protective effect and mechanism of enhanced expression of endogenous macrophage migration inhibitory factor (MIF) on cardiac ischemia-reperfusion (I/R) injury.

ArgR regulates motility and virulence through positive control of flagellar genes and inhibition of diguanylate cyclase expression in Aeromonas veronii.

Flagella are essential for biofilm formation, adhesion, virulence, and motility. In this study, the deletion of argR resulted in defects in flagellar synthesis and reduced motility, nevertheless, the underlying mechanism by which ArgR regulated bacterial motility remained unclear. ChIP-Seq and RNA-Seq analysis revealed that ArgR regulated the expression of flagellar genes, concluding two-component system flrBC and multitudinous flagellar structure genes.

A-D-A Molecular Design Strategy Enabling Ultrasensitive NIR Vapor Sensing.

Thin-film fluorescent chemosensors, characterized by their tunable design, high selectivity, and exceptional sensitivity, hold significant promise for gas detection applications. However, the simultaneous realization of the 3S attributes (sensitivity, selectivity, and stability) remains a formidable challenge, particularly in the underexplored field of near-infrared (NIR) gas detection. In this work, we employ an acceptor-donor-acceptor (A-D-A) molecular design strategy to drive the development of an organic semiconductor fluorescent material with a progressive red shift in the emission wavelength.

Evaluation of low nitrogen resistance of germplasm during the seed germination period.

Synthesis and Preclinical Evaluation of Dual-Specific Probe Targeting Glypican-3 and Prostate-Specific Membrane Antigen for Hepatocellular Carcinoma PET Imaging.

Positron emission tomography (PET) is a promising modality for early diagnosis, accurate detection, and staging of hepatocellular carcinoma (HCC). Hereby, a dual-specific probe targeting Glypican-3 (GPC3) and prostate-specific membrane antigen (PSMA) was evaluated for HCC PET imaging. The probe was prepared by conjugating TJ12P2, a GPC3-targeting peptide previously reported by our group, to a highly potent PSMA inhibitor via a polyethylene glycol linker and further tethered to the 1,4,7-triazacyclononane-1,4,7-triacetic acid (NOTA) chelator.

Fast-speed and low-power-consumption optical phased array based on lithium niobate waveguides.

Inhibition of hepatic PCSK9 as a novel therapeutic target ameliorates metabolic steatohepatitis in mice.

Background & Aims: Metabolic steatohepatitis (MASH) is closely related to metabolic disorders, and the main characteristics of MASH are hepatocyte steatosis with hepatocyte injury and inflammation. In severe cases, MASH can develop into liver cirrhosis. At present, there is no effective treatment for MASH.

Discovery of potent hypoxia-inducible factor-1α (HIF-1α) degraders by proteolysis targeting chimera (PROTAC).

Under hypoxic conditions in tumor cells, HIF-1α is unable to bind to VHL E3 ligase due to the blocked hydroxylation reaction, resulting in impaired degradation and intracellular accumulation. Mounting evidences show a close association between HIF-1α overexpression and drug resistance, treatment failure, and increased mortality. To address HIF-1α overexpression, we innovatively introduced an E3 ligase ligand to the HIF-1α inhibitor IDF-11774 using the PROTACs strategy, aiming to reactivate the degradative pathway impeded under hypoxia, and thereby achieve the degradation of HIF-1α protein under hypoxia.

Becoming Eligible for Long-Term Care Insurance in China Brought More Ageing at Home: Evidence from a Pilot City.

Person-centered long-term care systems, integral to healthy ageing, should empower older people to achieve ageing in place. Yet evidence on the impact of the design of long-term care systems on older people's choice of places of ageing, especially that from developing countries, is limited. Taking the introduction of Long-Term Care Insurance (LTCI) in City X of China as a policy shock, we examined the impact of becoming eligible for LTCI on program beneficiaries' choice of places of ageing-institution or home-before they started to receive any actual benefit.

A d-Cd Cluster Containing Sandwich-Type Arsenotungstate Exhibiting Fluorescent Recognition of Carcinogenic Dye in Methanol.

A d-Cd cluster containing sandwich-type arsenotungstate [CHN][CdCl(B--AsWO)] was synthesized and its structure characterized through elemental analyses, X-ray powder diffraction (XRPD), IR spectroscopy, X-ray photoelectron spectroscopy (XPS), and single-crystal X-ray diffraction. The X-ray analysis revealed that the molecular unit of the compound consists of a captivating tetra-Cd-substituted sandwich-type polyoxoanion, accompanied by six elegantly protonated 1,2-diaminopropane as counter ions. The further novelty of the tetranuclear cadmium cluster lies in its occupied chlorine atom sites.
