Acute pain transfusion reaction in a patient with thalassemia: In‐depth characterization of short‐ and long‐term phenotypes

Transfusion, EarlyView.
Abstract Background Acute pain transfusion reaction (APTR) is a rare, under‐recognized condition of unknown etiology. It can cause significant distress in recipients, necessitating symptomatic management and, occasionally, hospitalization. Study Design and Methods Here, we present an APTR event in an adult subject with transfusion‐dependent thalassemia

From Prebiotic Catalysts to Modern Applications: How Early Catalysts Inspire Today's Innovations

Israel Journal of Chemistry, Volume 66, Issue 4, July 2026.
Simple catalytic systems that may have operated under prebiotic conditions offer useful molecular principles for the design of modern functional materials. By examining how amino acids, peptide assemblies, and metal complexes achieve catalysis through simple chemical features, this review highlights how prebiotic chemistry can inspire new strategies ...

In silico prediction and structural characterization of multifunctional bioactive peptides released from olive proteins

Journal of the Science of Food and Agriculture, Volume 106, Issue 9, Page 5463-5482, July 2026.
Abstract BACKGROUND Olive (Olea europaea L.) byproducts, such as seeds and leaves, are abundant agro‐industrial residues and represent underexplored protein sources with potential health relevance. However, the repertoire of bioactive peptides that may be released from olive proteins during gastrointestinal digestion remains poorly characterized.

Mass Spectrometry Structural Proteomics Enabled by Limited Proteolysis and Cross‐Linking

Mass Spectrometry Reviews, Volume 45, Issue 4, Page 644-671, July/August 2026.
ABSTRACT The exploration of protein structure and function stands at the forefront of life science and represents an ever‐expanding focus in the development of proteomics. As mass spectrometry (MS) offers readout of protein conformational changes at both the protein and peptide levels, MS‐based structural proteomics is making significant strides in the
