Sodium-glucose cotransporter-2 (SGLT-2) inhibitors represent a cutting-edge class of oral antidiabetic therapeutics that operate through selective inhibition of glucose reabsorption in proximal renal tubules, consequently augmenting urinary glucose excretion and attenuating blood glucose levels. Extensive clinical investigations have demonstrated their profound cardiovascular efficacy. Parallel basic science research has elucidated the mechanistic pathways through which diverse SGLT-2 inhibitors beneficially modulate pulmonary vascular cells and arterial remodeling.

Addressing the challenges of the efficiency and stability of red perovskite nanocrystals is imperative for the successful deployment of these materials in displays and lighting applications. the structural dynamic changes of red perovskite quantum dots (PQDs) are explored using a flow chemistry system to solve the above hurdles. First, the ultrabright red-emitting PQDs of CsPb(Br,I) are achieved by adjusting ligand distribution (oleic acid and oleyamine) in combination with different flow rates and equivalence ratios.

Bacterial wilt caused by Ralstonia solanacearum is a devastating disease affecting a great many crops including peanut. The pathogen damages plants via secreting type Ш effector proteins (T3Es) into hosts for pathogenicity. Here, we characterized RipAU was among the most toxic effectors as ΔRipAU completely lost its pathogenicity to peanuts.

Polyethylene oxide (PEO)-based electrolytes are essential to advance all-solid-state lithium batteries (ASSLBs) with high safety/energy density due to their inherent flexibility and scalability. However, the inefficient Li+ transport in PEO often leads to poor rate performance and diminished stability of the ASSLBs. The regulation of intermolecular H-bonds is regarded as one of the most effective approaches to enable efficient Li+ transport, while the practical performances are hindered by the electrochemical instability of free H-bond donors and the constrained mobility of highly ordered H-bonding structures.

Emerging evidence demonstrates that inducing ferroptosis, a nonapoptotic programmed cell death mode, holds significant potential for tumor treatment. However, current ferroptosis strategies utilizing exogenous Fenton-type heavy metal species or introducing glutathione (GSH)/glutathione peroxidase 4 (GPX4) suppressants are hampered by latent adverse effects toward organisms, while utilizing endogenous iron may cause undesirable tumor angiogenesis through specific signaling pathways. Here, a ferric ion (Fe)-responsive and DNAzyme-delivered coordination nanosystem (ZDD) is developed to achieve a novel scheme of synergistic tumor-specific ferroptosis and gene therapy, which modulates and harnesses the endogenous iron in tumors for inducing ferroptosis while intercepting tumor angiogenesis to enhance therapeutic efficacy.

The exchange bias (EB) effect is a fundamental magnetic phenomenon, in which the exchange bias field/coercive field ratio (|H/H|) can improve the stability of spintronic devices. Two-dimensional (2D) magnetic heterostructures have the potential to construct low-power and high-density spintronic devices, while their typically air unstable and |H/H| lesser, limiting the possibility of applications. Here, 2D CrTe nanosheets have been systematically synthesized with an in situ formed ≈2 nm-thick Te doped CrO layer (Te-CrO) on the upper surface by chemical vapor deposition (CVD) method.

Wide-bandgap perovskite solar cells (PVSCs), a promising top-cell candidate for high-performance tandem solar cells, often suffer from larger open-circuit voltage (V) deficits as the bandgap increases. Surface passivation is a common strategy to mitigate these V deficits. However, understanding the mechanisms underlying the differences in passivation effects among various types of molecules remains limited, which is crucial for developing universal interface passivation strategies and guiding the design of passivation molecules.

Nitrogen (N) retention is a critical ecosystem function associated with sustainable N supply. Lack of experimental evidence limits our understanding of how grassland N retention can vary with soil acidification. A N-labeling experiment was conducted for 2 years to quantify N retention by soil pathways and plant functional groups across a soil-acidification gradient in a meadow.

Formamidinium lead iodide (FAPbI) perovskite films, ensuring optically active phase purity with uniform crystal orientation, are ideal for photovoltaic applications. However, the optically active α-FAPbI phase is easy to degrade into δ-phase due to numerous defects within randomly oriented films. Here, a "quasi-2D" perovskite template is pre-deposited on the film surface within the crystallization process based on the two-step preparation technology, which directly induced pure and highly orientated crystallization of α-FAPbI across the downward growth process.

During cancer peritoneal metastasis (PM), conventional antigen-presenting cells (dendritic cells, macrophages) promote tumorigenesis and immunosuppression in peritoneal cavity. While intraperitoneal immunotherapy (IPIT) has been used in clinical investigations to relieve PM, the limited knowledge of peritoneal immunocytes has hindered the development of therapeutic IPIT. Here, a dendritic cell-independent, next-generation IPIT is described that activates peritoneal cavity B (PerC B) cell subsets for intraperitoneal anti-tumor immunity via exogenous antigen presentation.

Wide dynamic range compression (WDRC) and noise reduction both play important roles in hearing aids. WDRC provides level-dependent amplification so that the level of sound produced by the hearing aid falls between the hearing threshold and the highest comfortable level of the listener, while noise reduction reduces ambient noise with the goal of improving intelligibility and listening comfort and reducing effort. In most current hearing aids, noise reduction and WDRC are implemented sequentially, but this may lead to distortion of the amplitude modulation patterns of both the speech and the noise.

It is well known that hydroxyl radical (OH) can be largely produced either through the classic iron-mediated inorganic-Fenton system or our recently discovered haloquinones/HO organic-Fenton-like system, but rarely produced via thiol compounds. Here, unexpectedly, we found that OH can be unequivocally generated by incubation of HO and mercaptotriazole (MTZ), a typical heterocyclic thiol which has been used as an environmentally friendly corrosion inhibitor for mild steel. By the complementary applications of HPLC-MS and oxygen-18 isotope-labeling method, MTZ-derived sulfenic (MTZ-SOH) and sulfinic acids were detected and identified as transient intermediates, and sulfonic acid as final products.

Liquid biopsies are expected to advance cancer management, and particularly physical cues are gaining attention for indicating tumorigenesis and metastasis. Atomic force microscopy (AFM) has become a standard and important tool for detecting the mechanical properties of single living cells, but studies of developing AFM-based methods to efficiently measure the mechanical properties of circulating tumor cells (CTCs) in liquid biopsy for clinical utility are still scarce. Herein, we present a proof-of-concept study based on the complementary combination of AFM and microfluidics, which allows label-free sorting of individual CTCs and subsequent automated AFM measurements of the mechanical properties of CTCs.

Protein methylation has attracted increasing attention due to its significant regulatory roles in various biological processes. However, the diversity of methylation forms, subtle differences between methylated and nonmodified sites, and their ultralow abundances pose substantial challenges for capturing and isolating methylated peptides from biological samples. Herein, we develop a chromatographic method that utilizes 4-sulfonylcalix[4]arene (SC4A) as a mobile phase additive and Click-Maltose as the stationary phase to separate methylated/nonmethylated peptides through the adsorption of the SC4A-(Me3) complex.

The integration of hydrogen-bonded organic frameworks (HOFs) with flexible electronic technologies offers a promising strategy for monitoring detailed health information, owing to their inherent porosity, excellent biocompatibility, and tunable catalytic capabilities. However, their application in wearable and real-time health monitoring remains largely unexplored, primarily due to the mechanical mismatch between the traditionally fragile HOFs particles and the softness of human skin. Herein, this study demonstrates an epidermal biosensor that maintains reliable sensing capability even under extreme deformation and complex environmental conditions by integrating HOFs films with wavy bioelectrodes.
