Article Abstract
The development of active food packaging has evolved rapidly in recent years, offering innovative solutions to enhance food preservation and safety while addressing sustainability challenges. This review compiles and analyzes recent advancements (2019-2024) in release-type active packaging, focusing on essential oils, natural extracts, and phenolic compounds as active agents. Primarily plant-derived, these compounds exhibit significant antioxidant and antimicrobial activities, extending shelf life and enhancing food quality. Technological strategies such as encapsulation and polymer blending have been increasingly adopted to overcome challenges related to volatility, solubility, and sensory impact. Integrating bio-based polymers, including chitosan, starch, and polylactic acid, further supports the development of environmentally friendly packaging systems. This review also highlights trends in compound-specific research, release mechanisms, and commercial applications, including a detailed analysis of patents and case studies across various food matrices. These developments have already been translated into practical applications, such as antimicrobial sachets for meat and essential oil-based pads for fresh produce. Moreover, by promoting the valorization of agro-industrial by-products and the use of biodegradable materials, emission-type active packaging contributes to the principles of the circular economy. This comprehensive overview underscores the potential of natural bioactive compounds in advancing sustainable and functional food packaging technologies.

Background: Plasmacytoid dendritic cells (pDCs) are a specialized subset of dendritic cells known for their ability to produce type I interferon (IFN I), contributing to antiviral defense and the pathogenesis of autoimmune diseases like systemic lupus erythematosus (SLE). In SLE patients, pDCs are excessively activated, leading to overproduction of IFN-α, which plays a critical role in disease progression. However, no bibliometric analysis has been conducted on the relationship between pDCs and SLE.

Asthma is a chronic inflammatory respiratory disease influenced by genetic and environmental factors. Emerging evidence suggests that microplastics and nanoplastics (NPs) pose significant health risks. When inhaled, these tiny particles can accumulate in the lungs, triggering inflammation, oxidative stress, and other disruptions in pulmonary function.

Bioprotective LAB3 cells that produce bacteriocin-like substances were entrapped in 4% (w/w) sodium alginate matrices, either with or without 10% (w/w) sodium caseinate. The effects of bead formulation-alginate alone or combined with caseinate, with or without the addition of 20% (w/w) MRS broth or M17 broth-on the culturability of LAB3 cells within the beads and their anti activity were assessed over 12 days of storage at 30 °C in closed bottles. Calcium-alginate-caseinate beads supplemented with MRS broth proved most effective in preserving both culturability and anti- activity.
