A Focus on Natural Autophagy Modulators as Potential Host‐Directed Weapons Against Emerging and Re‐Emerging Viruses

Medicinal Research Reviews, EarlyView.
ABSTRACT Autophagy is a highly conserved intracellular process involved in maintaining homeostasis and in the degradation of damaged organelles and external pathogens. Nature provides complex and varied reservoirs of scaffolds and chemical entities that may have a pivotal role in the search for new therapeutic leads.

Artichoke Bracts and Stems Residues as Active Filler for Poly(Butylene Succinate‐Co‐Adipate) (PBSA) Composites: From Agro‐Waste to a New Sustainable Material

Polymer Composites, EarlyView.
PBSA‐based biocomposites made from artichoke bract and stem powders have been characterised and formulated for agricultural and food applications, such as active mulching films. ABSTRACT In the context of a growing bioeconomy and the drive for sustainable materials, new biocomposites were formulated by incorporating poly(butylene succinate‐co‐adipate) (

Small grassland patches are hotspots for medicinal plants and associated phytochemical diversity in European agricultural landscapes

PLANTS, PEOPLE, PLANET, EarlyView.
Besides being important components of landscape‐level biodiversity, medicinal plants are essential resources for traditional and modern healthcare. However, human‐driven biodiversity loss has resulted in the decline of medicinal plant populations. By maintaining connections between nature, culture, and people, sacred natural sites can help counteract ...
