Specific Protein Quantification by Radioimmuno-Dot-Blot Assay for Complex Mixture Samples Utilizing Strep-Tag and Tritium-Labeled Strep-Tactin.

Accurately quantifying specific proteins from complex mixtures like cell lysates, for example, during in vivo studies, is difficult, especially for aggregation-prone proteins. Herein, we describe the development of a specific protein quantification method that combines a solid-state dot blot approach with radiolabel detection via liquid scintillation counting. The specific detection with high sensitivity is achieved by using the Twin-Strep protein affinity tag and tritium-labeled Strep-TactinXT probe.

Chondroitin Sulfate Nanovectorized by LC-PUFAs Nanocarriers Extracted from Salmon () by Green Process with Decreased Inflammatory Marker Expression in Interleukin-1β-Stimulated Primary Human Chondrocytes In Vitro Culture.

Chondroitin sulfate (CS), a glycosaminoglycan, supports health through various physiological functions, including tissue protection, bone growth, and skin aging prevention. It also contributes to anticoagulant or anti-inflammatory processes, with its primary clinical use being osteoarthritis treatment. This study presents the results of the valorization of lipids and CS, both extracted from salmon co-products through enzymatic processes.

Teaching Abolition Medicine: Best Practices for Centering Criminalized Communities in Medical Education.

Mass incarceration is a significant structural determinant of health, affecting incarcerated individuals, their families, and communities, with profound racial disparities. Health care professionals have an opportunity to reduce these inequities through abolition medicine. Abolition in health care means rewriting how doctors relate to patients labeled as criminal and is not a new checklist that can be imposed on the existing curriculum.

Phase separation drives the folding of recombinant collagen.

Recombinantly produced collagens present a sustainable, ethical, and safe substitute for collagens derived from natural sources. However, controlling the folding of the recombinant collagens, crucial for replicating the mechanical properties of natural materials, remains a formidable task. Collagen-like proteins from willow sawfly are relatively small and contain no hydroxyprolines, presenting an attractive alternative to the large and post-translationally modified mammalian collagens.

gastrointestinal digestion of marine oil emulsions and liposomal solutions: fate of LC-PUFAs upon lipolysis.

The bioaccessibility and bioavailability of dietary fatty acids depend on the lipid to which they are esterified, the organisation of theses lipids in water and their recognition by lipolytic enzymes. In this work, we studied the release of marine long-chain polyunsaturated fatty acids (LC-PUFA), depending on their presentation either in the form of phospholipids (PL) or triacylglycerol (TAG). Two formulations based on marine PL or TAG extracted from salmon heads () were prepared.
