Fecal bile acid dysmetabolism and reduced ursodeoxycholic acid correlate with novel microbial signatures in feline chronic kidney disease

Frontiers in Microbiology
BackgroundMicrobial-derived secondary bile acids (SBAs) are reabsorbed and sensed via host receptors modulating cellular inflammation and fibrosis. Feline chronic kidney disease (CKD) occurs with progressive renal inflammation and fibrosis, mirroring the

Correlation Between the Molecular Structure of Metal‐Supporting Ligands and Catalysis in the Oxygenase‐Mimicking Immobilized Metal Complex Catalysts

European Journal of Inorganic Chemistry, Volume 29, Issue 16, 4 June 2026.
The correlation between the structures of metal complexes immobilized in the mesopores of hydrophobically modified silicate supports was examined in relation to the catalytic activities toward C‐H oxidation. On the alkene oxidation with H2O2, the iron catalyst bearing bis(imidazolyl)methane ligand promotes allylic oxidation, whereas the mononuclear ...

Real-Time Single Frequency Precise Point Positioning Using SBAS Corrections

, 2016
Real-time single frequency precise point positioning (PPP) is a promising technique for high-precision navigation with sub-meter or even centimeter-level accuracy because of its convenience and low cost. The navigation performance of single frequency PPP

Saponin-based adjuvant uptake and induction of antigen cross-presentation by CD11b+ dendritic cells and macrophages

npj Vaccines
Saponin-based adjuvants (SBAs) distinguish themselves as vaccine adjuvants by instigating a potent activation of CD8+ T cells. Previously, we discovered SBA’s ability to induce cross-presentation in dendritic cells (DCs) leading to CD8+ T cell activation.

Bridging Liquid and Gas Phase Catalysis for Abiotic CO2 Conversion to Prebiotic Organics Over Mesoporous Silica‐Supported Ni–Co Catalysts

Advanced Synthesis &Catalysis, Volume 368, Issue 11, 3 June 2026.
Under simulated hydrothermal vent conditions, Ni⋅Co bimetallic catalysts supported on silica convert CO2 and H2O into key metabolites such as formate, methanol, and ethanol. Water plays a critical role in CO2 adsorption and product selectivity, shaping catalytic performance across both liquid and gas phases.

Modeling of Ionospheric Delay for SBAS Using Spherical Harmonics Functions

, 2013
In SBAS (satellite‐based augmentation system), it is important to estimate ionospheric delay accurately to guarantee userʹs accuracy and integrity. Grid based ionospheric models are generally used to estimate ionospheric delay for SBAS.

Synergistic Sunlight‐Activated Photodynamic and Near‐Infrared‐Induced Mild Photothermal Therapy for Infected Wound Healing Using Functionalized Nano‐Bi2WO6 Composites

Advanced Science, Volume 13, Issue 32, 9 June 2026.
This work proposes a multifunctional Bi2WO6:Yb,Er@CuS@CS nanocomposite that integrates photodynamic therapy (PDT), near‐infrared‐triggered photothermal therapy (PTT), and Cu2+ release for infected wound repair. The nanocomposite demonstrates enhanced antibacterial efficacy via combined PDT, PTT, and Cu2+ release, effective immunomodulatory by mild ...

Role of Epoxide Functionalization of Amines for Development of Direct Air Capture Sorbents with High Cyclic Working Capacity at Low Desorption Temperatures

Advanced Science, Volume 13, Issue 34, 19 June 2026.
Appropriate butylene oxide (BO) functionalization of amines (polyethyleneimine (PEI1200 and PEI300) and tris(2‐aminoethyl)amine (TREN)) enables excellent cyclic working capacities (WCcyclic) at low desorption temperatures (40−70°C). Notably, 0.30BO‐PEI300‐SY and 0.54BO‐TREN‐SY show the highest WCcyclic at 45 and 40°C, respectively.
