Biocomposites based on collagen and keratin with properties for agriculture and industrie applications

Introduction For the most part, scientific studies dedicated to biocomposites based on collagen and keratin have been oriented towards the medical field, especially for regeneration, vascular and cardiac reconstruction, cosmetic treatments ( 1 ). Studies on collagen mixtures with synthetic polymers have been aimed both at making materials for medical use ( 2 , 3 ) and for industrial applications such as biodegradable films, finishing binders, adhesives for the wood industry ( 4 ). For example, studies on collagen and keratin extracts used in the formulation

Indoor air pollution and the contribution of biosensors

, adhesives, finishes/coatings are used due to its affordability. However, some materials continuously emit harmful vapors over time, and the ventilation systems may not effectively remove or dilute these emissions. Personal computers are another source of pollution. After being in service for 500 hours (3 months of office use), PCs were found to emit phenol, toluene, 2-ethylhexanol, formaldehyde, and styrene ( 6 ). Even though most pollutants are found in minute concentrations that are much lower than proposed existing guidelines, constant exposure to multicomponent

Physiological role of Prion Protein in Copper homeostasis and angiogenic mechanisms of endothelial cells

may represent a compensatory response in order to overcome the preeclamptic condition ( 27 ). In this work we demonstrated PrP expression in HUVEC endothelial cell lines and tried to establish: i. whether PrP can contribute to the endothelial function maintenance through copper availability modulation, and/or ii. to prove its involvement in cellular architecture and in adhesive cellular properties; both aspects were investigated in the HUVEC endothelial model, in which the expression of PrP was silenced by an RNA interference approach. The knockdown cells did not
