Towards Bio‐Based Benzoxazines (2015–2025): A Critical Review of Renewable Building Blocks, Formaldehyde‐Free Aldehydes, and ECHA Hazard Landscape

open access: yesPolymers for Advanced Technologies, Volume 37, Issue 8, August 2026.
ABSTRACT This review provides a critical overview of research on fully bio‐based benzoxazines over the period 2015–2025. A bibliometric analysis based on the Web of Science database is used to map how the field has evolved and to identify the renewable building blocks that have been most widely adopted.

Sulfur Amino Acids in Diet-induced Fatty Liver: A New Perspective Based on Recent Findings

open access: yesMolecules, 2014
The relationship of sulfur amino acids to diet-induced fatty liver was established 80 years ago, with cystine promoting the condition and methionine preventing it.

Preparation and Properties of Redox-Responsive Micelles Based on Carboxylmethyl Hydroxypropyl Chitosan [PDF]

open access: yesBIO Web of Conferences
By employing carboxymethyl hydroxypropyl chitosan (HPCMS) as the hydrophilic unit, deoxycholic acid (DOCA) as the hydrophobic unit, and cystamine (CYS) as the linker, the synthesis involved a two-step amidation process.

Soft Hardware, Flowing Software: Reconfigurable Microfluidics for Adaptable Chemical Computation

open access: yesAdvanced Materials, Volume 38, Issue 39, 13 July 2026.
A reconfigurable microfluidic platform based on soft, photo‐printable, and chemically erasable hydrogel structures printed and erased in situ is used to control flow routing, mixing, chemical patterning, and even chemical computing. Using hardware to control chemical computations decouples logic function from molecular composition, demonstrated via ...

Fully Wireless and Flexible Valves for Multiplexed and Prolonged Intravesical Liquid Release

open access: yesAdvanced Healthcare Materials, Volume 15, Issue 23, 19 June 2026.
A fundamental mechanism for the simultaneous control of multiple magnetic valves is reported in a miniature soft robotic patch for intravesical drug delivery, enabling fully wireless and programmable liquid release. Integrated with a bioadhesive interface and induction‐coupling‐based liquid volume sensing, the soft robotic patch is promising to enable ...

Cystamine slows but not inverses the progression of monocrotaline-induced pulmonary arterial hypertension in rats.

open access: yesCanadian Journal of Physiology and Pharmacology, 2018
Tissue transglutaminase (TG2) plays an important role in pulmonary arterial hypertension (PAH). Previous research indicate that TG2 and protein serotonylation catalyzed by TG2 are upregulated in PAH. Serotonin transporter inhibitor fluoxetine ameliorates

Transglutaminase 2 expression is increased as a function of malignancy grade and negatively regulates cell growth in meningioma. [PDF]

open access: yesPLoS ONE, 2014
Most meningiomas are benign, but some clinical-aggressive tumors exhibit brain invasion and cannot be resected without significant complications. To identify molecular markers for these clinically-aggressive meningiomas, we performed microarray analyses ...
