Pinus nigra and Pinus brutia Extracts Inhibit Quorum Sensing in Pseudomonas aeruginosa PAO1 with Minimal Impact on Fibroblast Cell Viability and Calcium Deposition

open access: yesFood Science &Nutrition, Volume 14, Issue 4, April 2026.
Extracts of Pinus nigra and Pinus brutia inhibit quorum sensing in Pseudomonas aeruginosa PAO1 by reducing pyocyanin and elastase production. This effect is associated with the downregulation of QS‐related genes, including lasR, lasI, rhlI, and rhlR. Additionally, the extracts exhibit minimal, dose‐ and time‐dependent effects on the metabolic activity ...

Non‐redox Lewis Acids Supported Pd‐Catalyzed C—C /C—H Activation and Accession to Produce Pharmaceutical Intermediates

open access: yesChemistryOpen, Volume 15, Issue 4, April 2026.
Palladium is a simple and versatile redox‐active metal that plays a crucial role in the oxidation reactions for organic synthesis and production of pharmaceutical intermediates. Notably, there has been significant progress with Lewis acids (LAs), which are non‐redox metal ions promoting Pd(II)‐catalyzed oxidation via C—H and C—C bond activation.

Load‐Bearing Characteristics of SLA‐Fabricated Octahedral Porous Structures

open access: yesStrain, Volume 62, Issue 2, April 2026.
A combined experimental–numerical framework was developed to evaluate SLA–fabricated octahedral and pillar–reinforced lattice structures under compression, shear, and torsion. Small increases in infill density produced nonlinear gains in stiffness and strength, reaching a 255% rise in elastic modulus at low porosity. Pillar reinforcement enhanced shear

Homotopy decompositions and K-theory of Bott towers [PDF]

open access: yes, 2004
We describe Bott towers as sequences of toric manifolds M^k, and identify the omniorientations which correspond to their original construction as toric varieties. We show that the suspension of M^k is homotopy equivalent to a wedge of Thom complexes, and
