This work presents a review related to the obtainment of cellulose from different structures in agro-industrial residues, both for application in the food industry and for the reinforcement of other materials. Cellulose nanofibers are produced by the heart of palm (Bactris gasipaes) industry in Brazil and are used as a stabilizer in avocado oil emulsions; conversely, cellulose nanocrystals are produced in waste from the tequila industry (Agave tequilana Weber var. Azul) in Jalisco, Mexico, and are used for reinforcement applications. [ABSTRACT FROM AUTHOR]

The Amazon represents the world's greatest biodiversity and covers different countries in South America, including Brazil with the largest area. The interaction between the resident population of this area and its ecosystem is responsible for an intense exposure to venomous animals, which are considered an important health issue in the region. Therefore, the 1st International Symposium on Research in Venomous Animals, held from 2 May to 5 May 2023 in the city of Manaus in the state of Amazonas in Brazil, aimed to address animal envenomation aspects in the Brazilian Amazon and the exchange of ideas and knowledge between research groups from around the world. The event was attended by graduate students as well as renowned researchers from the Americas, Europe, and Asia. The event presented a multidisciplinary and translational approach in the area of toxinology, including themes such as clinical envenomation (clinical management, pathophysiology, and public policy strategies), preclinical studies, biological aspects of venomous animals' venoms (venom composition/variation and geographical distribution), interdisciplinary studies on health anthropology and economics, and bioprospecting aspects (toxins with therapeutic and/or technological potential).
