Photoisomerization in Cyclic Dipeptide Derivatives: Photoswitchable Supramolecular Hydrogels and the Discovery of Hemipiperazine Photoswitches

ChemPhotoChem, Volume 10, Issue 3, March 2026.
Photoswitchable cyclic dipeptides (CDPs) can be used to prepare hydrogels that reversibly dissipate upon irradiation, or to photomodulate the development of living organisms. We report here applications and perspectives for CDPs containing azobenzene photoswitches or newly discovered hemipiperazine photoswitches in smart materials and biological ...

Oral Acute Toxicity and Genotoxicity of Heteroctenus junceus Scorpion Venom

Veterinary Medicine and Science, Volume 12, Issue 2, March 2026.
The Heteroctenus junceus scorpion venom is a very popular natural extract used in traditional medicine in Cuba. In clinically relevant experimental settings, scorpion venom does not induce general toxicity or an increase in the frequency of micronucleus formation in erythrocytes.

Characterization of Phytoene Desaturase Knockout Carotenoid‐Deficient Microalgal Mutants Generated by Cas9‐Ribonucleoprotein Complexes

Physiologia Plantarum, Volume 178, Issue 2, March/April 2026.
ABSTRACT Phytoene desaturase (PDS; EC 1.3.5.5) is a key enzyme of the carotenoid biosynthetic pathway, catalyzing the desaturation of phytoene, precursor of all carotenoids. In this study, several PDS‐knockout (PDS‐KO) transformants of the chlorophyte microalga Chlamydomonas reinhardtii were generated using a reverse genetics strategy. Two single guide

pH‐Tunable Material Properties of Glycine‐Rich Condensates from Tick Bioadhesive

Advanced Functional Materials, Volume 36, Issue 10, 2 February 2026.
This work studies the influence of pH on the phase separation behavior of a disordered glycine‐rich protein found in tick bioadhesive. The results show profound impact on the propensity of coacervation, condensate microstructure and viscosity, amphiphilicity of the peptides, and effective encapsulation of therapeutic molecules.

Structural and Functional Properties of Araucaria araucana and Araucaria angustifolia Seed Proteins as a Plant‐Based Food Source

Sustainable Food Proteins, Volume 3, Issue 4, December 2025.
Morphologically, A. angustifolia seeds were significantly larger, while A. araucana exhibited more regular, triangular shapes. Proximate composition revealed a carbohydrate‐rich profile in both species, with a significantly higher lipid content in A. araucana. Amino acid analysis showed similar profiles, with high levels of aspartic and glutamic acids.

Fe‐Photocatalyzed Decarboxylative Giese‐Type Reaction of α‐N, O or S Carboxylic Acids: Insight into the Mechanism of the Radical Formation

Advanced Synthesis &Catalysis, Volume 367, Issue 21, November 13, 2025.
Electron‐deficient alkenes can be functionalized with α‐amino, α‐alkoxy and α‐alkylthio radicals formed by Fe‐photocatalyzed decarboxylation of the corresponding carboxylic acids. The reactions proceed under smooth ligandless conditions with inexpensive base and in the absence of oxidant. A mechanistic computational TD‐DFT study supports the occurrence

Desarrollo y transferencia tecnológica de pastas funcionales extendidas con leguminosas Development and technological transfer of functional pastas extended with legumes

Archivos Latinoamericanos de Nutrición, 2009
La pasta de sémola es un alimento altamente consumido, cuyo valor biológico es bajo porque su proteína es deficiente en lisina. Sin embargo, si se extiende la sémola con leguminosas ricas en este aminoácido esencial, no sólo se produce una ...
