Ionic Covalent Organic Framework as Antibacterial Additive for Biobased Polymers.

The rise of antibiotic-resistant bacteria has created an urgent need for antibacterial materials. One of the most widespread strategies involves the covalent attachment of ionic moieties, which can, however, compromise the quality of the final polymers. Herein, we report the synthesis of ionic covalent organic framework nanoparticles via click postsynthetic modification.

Interleukin-6 as a prognostic marker in acute kidney injury and its klotho-dependent regulation.

Background And Objective: In acute kidney injury (AKI), a strong inflammatory component is activated in response to the renal damage, and one of the main mediators behind this process is the pro-inflammatory interleukin 6 or IL-6. Beside to this phenomenon, there are also alterations in different components of mineral metabolism, such as those dependent on fibroblast growth factor (FGF)23 and the anti-ageing cofactor klotho. The aim of this work was to explore the association between renal function and systemic levels of IL-6, as well as FGF23 and klotho in the early stages of AKI, analysing the predictive capacity of IL-6 in early mortality associated with AKI.

The Research Collaboratory for Structural Bioinformatics Protein Data Bank (RCSB PDB, RCSB.org), the US Worldwide Protein Data Bank (wwPDB, wwPDB.org) data center for the global PDB archive, provides access to the PDB data via its RCSB.

Boosting Photoconductivity by Increasing the Structural Complexity of Multivariate Covalent Organic Frameworks.

The assessment of the photoconductivity of Donor-Acceptor (D-A) ordered bulk heterojunctions is gaining attention for the development of innovative organic semiconductors in optoelectronics. Here, the synthesis of pyrene-based (D) Covalent Organic Frameworks, achieve through a multivariate reaction involving two distinct acceptors is reported (A). The products are characterized using powder x-ray diffraction, N sorption isotherms, electronic microscopy, and in silico calculations, among other techniques.

Magnetic Resonance Imaging (MRI) of Spanish Sheep Cheese: A Study on the Relationships between Ripening Times, Geographical Origins, Textural Parameters, and MRI Parameters.

The evolution of structural changes and the textural features during the ripening process of four varieties of Spanish sheep cheese were studied using Magnetic Resonance Imaging (MRI). Specifically, longitudinal () and transverse () relaxation times and apparent diffusion coefficient maps were analyzed. Also, proton density was used to improve the description of the structure of the cheeses.
