Endotoxins and Biological Implications—Review

ABSTRACT Endotoxins, also known as lipopolysaccharides (LPSs), are structural components of the outer membrane of Gram‐negative bacteria and some cyanobacteria. They are among the most potent pyrogens and remain a persistent challenge in environmental, occupational, and clinical...

Water relations and gas exchange across developmental stages in the páramo rosette Paepalanthus alpinus Körn. (Eriocaulaceae) in the tropical high Andes

Alpine environments impose strong and rapidly fluctuating constraints on plant function, yet ontogenetic modulation of physiological strategies in tropical alpine rosettes remains poorly understood. We examined stage-specific variations in leaf water potential and gas exchange of...

Intravascular ultrasound–guided versus angiography-guided endovascular interventions for peripheral artery disease: a systematic review and meta-analysis

Abstract Background Endovascular revascularization is a cornerstone therapy for peripheral artery disease (PAD), typically guided by angiography, which may underestimate vessel size and lesion complexity. The clinical benefit of intravascular ultrasound (IVUS) guidance remains un...

Frutopia: A Hybrid Tangible Serious Game for Multisensory Interaction and Tactile Exploration

Serious games have demonstrated significant potential for supporting learning, cognitive stimulation, and skill development. However, most existing solutions rely predominantly on visual and auditory interaction, while the integration of real tactile experiences remains limited d...

Stingless bee honeys: the missing piece in harmonized authenticity and quality standards

Stingless bee honeys are among the most chemically diverse and bioactive honeys yet remain largely excluded from international authenticity standards centered on Apis mellifera . This exclusion may limit equitable market participation and the sustainable valorization of indigenou...

Power, Governance and Resilience in a Chilean Fruit Agro-Export Value Chain: A Social Simulation Approach

The fruit agro-export value chain in northern Chile faces governance and water-related challenges that affect its resilience and long-term sustainability. In the context of sustainable agriculture, these challenges highlight the need for integrated approaches to understand how so...
