Metformin's effect on metabolic dysfunction-associated steatotic liver disease through the miR-200a-5p and AMPK/SERCA2b pathway.

Introduction: Metformin has shown benefits in treating metabolic dysfunction-associated steatotic liver disease (MASLD), but its mechanisms remain unclear. This study investigates miR-200a-5p's role in the AMPK/SERCA2b pathway to reduce liver fat accumulation and ER stress in MASLD.

Methods: A PA cell model induced by palmitic and oleic acids (2:1) was used to assess lipid accumulation via Oil Red O and Nile Red staining.

Solve the cause, not the symptom: Managerial myopia and environmental investment preferences.

Corporate executives often favor short-term "end-of-pipe" solutions to comply with environmental regulations. In this study, we examine how managerial myopia influences corporate preferences for environmental investments, using data from listed Chinese firms between 2007 and 2021. Grounded in the upper-echelon and time orientation theories, this analysis reveals that managerial myopia discourages environmental investments, with a more pronounced impact on preventive measures compared to treatment-focused approaches.

Crystal reconstructed cubic nickel oxide with energetic reactive interfaces for exceptional electrochromic smart windows.

Electrochromic smart windows can realize intelligent photothermal regulation by applying a low potential, which is of great significance for energy-saving buildings and achieving low carbon emission. However, the dense structure of conventional metal oxide electrochromic materials limits ion transport efficiency, resulting in poor electrochromic properties. Here, we propose a surface crystal reconstruction strategy for cubic NiO through phosphorylation (P-NiO) to build energetic reactive interfaces and enhance the electrochromic performance.

Enhanced quasi-meshing hotspot effect integrated embedded attention residual network for culture-free SERS accurate determination of Fusarium spores.

Determination of Fusarium spores is essential for precision control of Fusarium head blight and ensuring agri-food safety. As a highly sensitive real-time detection technique with rich fingerprint information and little influence from water, surface-enhanced Raman spectroscopy (SERS) has been widely applied in the determination of microorganisms. However, fungi determination faces significant challenges including low sensitivity, and poor specificity.

Revealing Single-Molecule Photocurrent Generation Mechanisms under On- and Off-Resonance Excitation.

We investigate photocurrent generation mechanisms in a pentacene single-molecule junction using subnanometer resolved photocurrent imaging under both on- and off-resonance laser excitation. By employing a wavelength-tunable laser combined with a lock-in technique, net photocurrent signals are extracted to elucidate photoinduced electron tunneling processes. Under off-resonance excitation, photocurrents are found to arise from photon-assisted tunneling, with contributions from three distinct frontier molecular orbitals at different bias voltages.

A New Optical Analysis System for Online Measurement of NO Temperature and Concentration in Combustion Processes.

In the combustion process, the nitric oxide (NO) concentration and temperature are considered to be highly related to the combustion efficiency. Currently, ultraviolet differential absorption optical spectroscopy (UV-DOAS) has become an ideal method for NO analysis due to its strong absorption characteristics in the UV spectral regime. However, since temperature and concentration have similar effects and complex correspondences on intensity, it is a challenge to achieve dual-indicator sensing of NO at this time.

Research progress and application prospects of animal models of group B Coxsackievirus infections.

Group B Coxsackieviruses (CVBs) consist of six serotypes, CVB1 to CVB6, which can clinically affect the heart, brain, liver, pancreas and other organs, causing myocarditis, encephalitis, myelitis, pancreatitis, hand-foot-and-mouth disease (HFMD) and other diseases, and can even lead to death. CVBs are widespread globally and highly contagious. However, there are currently no approved CVB vaccines or effective treatments.

Advances towards potential cancer therapeutics targeting Hippo signaling.

Decades of research into the Hippo signaling pathway have greatly advanced our understanding of its roles in organ growth, tissue regeneration, and tumorigenesis. The Hippo pathway is frequently dysregulated in human cancers and is recognized as a prominent cancer signaling pathway. Hence, the Hippo pathway represents an ideal molecular target for cancer therapies.

Identification of immune-related hub genes and potential molecular mechanisms involved in COVID-19 via integrated bioinformatics analysis.

COVID-19, caused by the SARS-CoV-2 virus, poses significant health challenges worldwide, particularly due to severe immune-related complications. Understanding the molecular mechanisms and identifying key immune-related genes (IRGs) involved in COVID-19 pathogenesis is critical for developing effective prevention and treatment strategies. This study employed computational tools to analyze biological data (bioinformatics) and a method for inferring causal relationships based on genetic variations, known as Mendelian randomization (MR), to explore the roles of IRGs in COVID-19.

Ligand-Tuned AgBiS Planar Heterojunctions Enable Efficient Ultrathin Solar Cells.

AgBiS quantum dots (ABS QDs) have emerged as highly promising candidates for photovoltaic applications due to their strong sunlight absorption, nontoxicity, and elemental availability. Nevertheless, the efficiencies of ABS solar cells currently fall far short of their thermodynamic limits due in large part to sluggish charge transport characteristics in nanocrystal-derived films. In this study, we overcome this limitation by tuning the surfaces of ABS semiconductor QDs via a solvent-induced ligand exchange (SILE) strategy and provide key insights into the role of surface composition on both - and -type charge transfer doping, as well as long-range charge transport.

Probiotic nanovesicles encapsulating baicalin: a strategy to overcome colorectal cancer.

Escherichia coli Nissle 1917 (EcN) is a unique probiotic utilized to treat inflammatory bowel disease and irritable bowel syndrome. Outer membrane vesicles (OMVs) from EcN can not only deliver pro-biotic anti-inflammatory molecules to cancer cells to exert anti-rectal cancer effects, but also deliver therapeutic drugs, genes, and other "cargoes" encapsulated in the vesicles to specific cells, making them an ideal vehicle for drug delivery. In this study, we successfully isolated OMVs of probiotic origin and obtained BCN-OMVs by encapsulating baicalin (BCN) in EcN-OMVs.

Label-free classification of atherosclerosis plaque via OCT and ultraviolet autofluorescence spectroscopy.

We proposed a label-free method for the identification and classification of atherosclerosis plaques by combining optical coherence tomography (OCT) with ultraviolet autofluorescence spectroscopy (uFLS). By aligning the OCT source and the FLS excitation beams, we were able to illuminate the same spot on plaques fixed to the integrated probe, which underwent rotational scanning. This setup enabled the detection of both OCT images and uFLS spectra of the plaques in a co-localized manner.
