Inactivation of Lipopolysaccharide-Biosynthesizing Genes Altered Lipids Composition and Intensity in .

Gram-negative bacteria possess an asymmetric outer membrane, where the outer leaflet consists of LPSs and the inner leaflet comprises phospholipids. , an opportunistic milk-borne pathogen that causes severe neonatal meningitis and bacteremia, displays diverse lipopolysaccharide (LPS) structures. As a barrier of the bacterial cell, LPSs likely influenced resistance to environment stresses; however, there are no research reports on this aspect, hindering the development of novel bactericidal strategies overcoming the pathogen's resilience.

Nanoparticle-mediated light-driven LAMP combined with test strips for sensitive and rapid visual detection of antibiotic resistance genes.

The South China Sea Mooring Array and its applications in exploring oceanic multiscale dynamics.

The South China Sea (SCS) is abundant with complex multiscale dynamic processes but their spatiotemporal variations, generation and evolution mechanisms, and mutual interactions remain inadequately understood due to the lack of long-term in situ observations. To explore oceanic multiscale dynamics in the SCS, the SCS Mooring Array (SCSMA) was began to be constructed since 2009. The SCSMA consists of ∼40 moorings and is the largest in situ ocean observing system in marginal seas worldwide.

IL-17A in gastric carcinogenesis: good or bad?

Cytokines, which are important to the tumor microenvironment (TME), play critical roles in tumor development, metastasis, and immune responses. Interleukin-17(IL-17) has emerged as a key biomarker in many malignancies; however, its precise involvement in gastric cancer is less fully understood. Elevated levels of IL-17 have been observed in stomach diseases such as infection and autoimmune gastritis, indicating that a sustained Th17 response may precede the development of gastric cancer.

Interface Engineering of Thin-Film Lithium Phosphorus Oxynitride Electrolyte by Appropriate Oxygen Plasma Treatment for Flexible All-Solid-State Supercapacitor.

The interfacial incompatibility between lithium phosphorus oxynitride (LiPON) and anode greatly deteriorates the performance of thin-film all-solid-state supercapacitors (ASSSCs). This article investigates oxygen plasma treatment to improve the interface. Through appropriate plasma treatment, a LiO/LiPO composite layer is formed by replacing nitrogen with oxygen at the LiPON surface owing to strong reactivity of oxygen plasma.

Reconfigurable CMOS-Compatible Supercapacitor-Diode Empowering Computation Efficiency for Human-Machine Interaction.

Biological system utilizes unidirectional ion flow to produce and transmit signals. To realize bioinspired artificial intelligence and thus seamless human-machine interaction, ion rectification devices should be developed. Here, a reconfigurable CMOS-compatible supercapacitor-diode (CAPode) is developed by resettling the pseudo-capacitive and electrochemical-double-layer-capacitive components of a lithium-ion pseudocapacitor into the positive and negative voltage regions respectively through engineering the redox peaks.

HMGB1 impacts the intestinal epithelial barrier by initiating NETs to regulate macrophage polarization.

High mobility group box 1 (HMGB1) has the capability of activating the immune response and taking part in macrophage polarization. Despite this, there is significant scope for exploration into how HMGB1 regulates macrophage polarization phenotype and influences intestinal epithelial barrier function. Investigating the role of HMGB1 in the creation of neutrophil extracellular traps (NETs) and the mechanism of its impact on macrophages could provide novel insights into intervening in intestinal inflammation and barrier damage.

LINC02139 interacts with and stabilizes XIAP to regulate cell proliferation and apoptosis in gastric cancer.

Previous reports showed that long non-coding RNA (lncRNA) participates in the development and progression of tumors. Nevertheless, the effect of LINC02139 and its mechanism on gastric cancer (GC) is still unknown. We revealed that LINC02139 is upregulated in GC cell lines and tissues and high LINC02139 expression was correlated with the advancement of GC in patients.

Prognostic role of prostate specific antigen kinetics in primary high volume metastatic hormonal sensitive prostate cancer treated with novel hormonal therapy agents.

The prognostic value of prostate-specific antigen (PSA) kinetics in primary high-volume metastatic hormone-sensitive prostate cancer (mHSPC) patients treated with novel hormonal therapy agents is still unclear. Here, we retrospectively reviewed the data of 102 patients with primary high-volume mHSPC who received novel hormonal therapy agents. The median follow-up was 32.

Defect-Mediated Formation of Oriented Phase Domains in a Lithium-Ion Insertion Electrode.

The performance and robustness of electrodes are closely related to transformation-induced nanoscale structural heterogeneity during (de)lithiation. As a result, it is critical to understand at atomic scale the origin of such structural heterogeneity and ultimately control the transformation microstructure, which remains a formidable task. Here, by performing in situ studies on a model intercalation electrode material, anatase TiO, we reveal that defects─both preexisting and as-formed during lithiation─can mediate the local anisotropic volume expansion direction, resulting in the formation of multiple differently oriented phase domains and eventually a network structure within the lithiated matrix.
