Extrusion Bioprinting for Wound Healing: Innovations in Functionalized Bioinks and Bioprinting Technology

Advanced Materials Technologies, Volume 11, Issue 18, 18 September 2026.
Extrusion‐based bioprinting (EBB) has emerged as a versatile biofabrication platform capable of precisely depositing bioinks composed of biomaterials, cells, and bioactive agents to generate patient‐specific, biomimetic skin constructs. This paper presents a state‐of‐the‐art and forward‐looking overview of EBB for wound healing, encompassing printing ...

Bioactive compounds in insects—Composition, extraction, functionality, food applications, and safety concerns

Food Biomacromolecules, Volume 3, Issue 3, Page 620-645, September 2026.
This review synthesizes 94 studies (2000–2025) exploring edible insects as sustainable sources of peptides, lipids, and chitin. Utilizing “green” extraction, these bioactives offer antioxidant and antimicrobial benefits for functional foods. However, addressing safety concerns like allergenicity and heavy metals through standardized frameworks remains ...

Developing an Analytical Framework for the Molecular Weight Analysis of Fish‐Derived Collagen Peptides in Beverages: A Multi‐Method Comparative Study

Food Science &Nutrition, Volume 14, Issue 9, September 2026.
An analytical framework was developed for molecular weight analysis of fish‐derived collagen peptides in beverages. Three GPC methods were compared, and matrix interference from excipients was excluded using a 20.5 min cutoff. Cubic polynomial fitting significantly improved inter‐method consistency.

Genetics of Celiac Disease in Southern Brazil: High‐Resolution HLA Haplotypes and Non‐HLA Polymorphisms

HLA, Volume 108, Issue 3, September 2026.
ABSTRACT Celiac disease (CeD) is an autoimmune enteropathy triggered by gluten ingestion in genetically predisposed individuals, who frequently present HLA‐DQ2 or HLA‐DQ8 haplotypes. To examine the genetic architecture of CeD in the admixed South Brazilian population, we sequenced the HLA alleles to high resolution and genotyped 16 non‐HLA ...
