The Reactive Extrusion Cationization of Starches as a Novel Physicochemical Surface Modification Method. [PDF]

Biopolymers
Native starches from different botanical sources were cationized by reactive extrusion using 3% glycidyltrimethylammonium chloride (GTAC). The process, performed under controlled thermal zones, promoted the incorporation of quaternary ammonium groups onto the starch backbone.

Gut Microbiota Diversity and Function in Adults With Type 2 Diabetes, Alzheimer's Disease, and Both Conditions. [PDF]

Int J Microbiol
Introduction Type 2 diabetes mellitus (T2DM) is known to increase the risk of Alzheimer’s disease (AD), but the role of the gut microbiota in this relationship is not fully understood. This study investigated the gut microbiota profiles of adults with T2DM, adults with AD, both conditions (AD–T2DM), and healthy controls to identify patterns associated ...

4D Printable Formulations of Mixed Low and High Molecular Weight Liquid Crystalline Units: A Versatile Route to Functional Soft Actuators. [PDF]

Macromol Rapid Commun
This work presents a practical approach for formulating 4D printable inks that incorporates substantial fractions of low molecular weight mesogens. By blending low molecular weight diacrylate or monoacrylate constituents with a high molecular weight main‐chain macromer, the resulting mixture proves suitable for direct ink writing, enabling mechanical ...

Dual Inhibition of COX-2/5-LOX Through Novel Hybrids of NSAIDs and Peptides: Insights from Molecular Dynamics Simulation and Per-Residue Decomposition. [PDF]

ChemistryOpen
Hybrid NSAID–aminoacid molecules have demonstrated excellent activity in inhibiting the cyclooxygenase/lipoxygenase system. Accordingly, the present study describes the synthesis of molecules of this kind, examining their behavior via docking, molecular dynamics simulations and per‐residue energy decomposition analyses.

High Childhood Leukemia Mortality Rates in Mexico Associated to Water Contamination in Areas of Oil and Gas Extraction

GeoHealth, Volume 10, Issue 7, July 2026.
Abstract Acute lymphoblastic leukemia (ALL) is the leading cause of death in Mexican children, yet water‐mediated environmental pathways remain largely unexplored as contributors to its spatial distribution. We analyzed ALL mortality records for individuals aged 0–19 years across all Mexican municipalities from 2003 to 2023, using publicly available ...

Lectin‐Modified Screen‐Printed Carbon Electrodes (SPE) for the Electrochemical Detection of Transferrin

Electroanalysis, Volume 38, Issue 4, April 2026.
We developed an impedimetric biosensor by electrochemically oxidizing screen‐printed carbon electrodes, allowing the covalent immobilization of Concanavalin A for selective holotransferrin detection. After the target protein is captured, the device monitors changes in charge–transfer resistance using electrochemical impedance spectroscopy.
