Biopolymer-based packaging materials are increasingly favored for their eco-friendly and biodegradable properties. Among the promising biopolymer materials, agar-based biodegradable films stand out since they are made from water and plasticizers like glycerol. However, they often suffer from reduced mechanical strength and higher moisture sensitivity compared to synthetic alternatives. To address these issues, this study explores the incorporation of silver nanoparticles (AgNPs) into agar-based films using Aloe ve...

Chamomile flower, a well-known medicinal plant, possesses significant antioxidant properties attributed to its diverse array of bioactive compounds, including antioxidant proteins. These proteins are vital in combating oxidative stress and neutralizing harmful free radicals. To fully harness the antioxidant potential of chamomile, it is imperative to optimize the extraction methods. This study evaluates the effectiveness of nonconventional mechanical extraction methods using ultrasound to extract antioxidant compo...

Harvested bee pollen has been used since ancient times for its healthy properties and nutritional value. In terms of composition, bee pollen contains a large number of different substances such as proteins, carbohydrates and lipids as well as phenolic organic compounds. The protein content is the second most abundant component, its levels (10 to 40%, w/w) depending on the type of plant. Recently, numerous studies have demonstrated the beneficial properties of pollen in promoting health and reducing the risk of dev...

Alzheimer?s disease, the most common age-related dementia worldwide, is characterized by two pathologies: deposition of ?-amyloid plaque and neurofibrillary tangles of hyperphosphorylated tau. To this date, several factors, such as oxidative stress, metal ions, or genetic factors are associated with Alzheimer`s diseases, but there are still some question marks regarding: (i) how the misfolding and aggregation of A? occurs and which is the aggregation mechanism; (ii) how the metal ions binds to A? and how they init...
