Sericin has been characterized as demonstrating a variety of bioactivities, establishing it as a valuable resource for biomedical and pharmaceutical applications. The diverse biological activities of sericin are likely linked to its unique biochemical composition and properties. This study aimed to assess the effect of origin, seasonality, and amino acid composition on the bioactivity of sericin samples from two Portuguese regions compared to commercial sericin.

The dispersion process of commercial ZnS:Mn particles and YVO:Eu particles synthesized by microwave reactor in aqueous solutions onto solid surface was performed using an ultrasonic atomizer. Two methods of particle deposition were used, one by moving the substrates while spraying and in the second the substrates were not moved.

A sample of 336 youth male players from five team sports (basketball, football, handball, volleyball, and water polo) completed the Parent-Initiated Motivational Climate Questionnaire-2 and the Performance Failure Appraisal Inventory. The results showed that perceived mother- and father-initiated motivational climates were related to fear of failure predispositions.

Microalgae are microorganisms that are rich in bioactive compounds, including pigments, proteins, lipids, and polysaccharides. These compounds can be utilized for a number of biomedical purposes, including drug delivery, wound healing, and tissue engineering. Nevertheless, encapsulating microalgae cells and microalgae bioactive metabolites is vital to protect them and prevent premature degradation.
