Biopolymer from Annona muricata residues as a potential sustainable raw materia...
Ramos, Igor F. S.; Dias, Samuel C.; Lopes, Talissa B. C.; Júnior, Francisco T. dos S. Silva; Araújo, Ricardo de; Gutierrez, Stanley J. C.Annona muricata is a fruit species belonging to the Annonaceae family, which is native to the warmer tropical areas of North and South America. A large amount of discarded residue from A. muricata is of interest for obtaining new industrial inputs. To propose the applications of the biopolymer from A. muricata residues (Biop_AmRs), this study aimed to characterize this input chemically and functionally, as well...
Development of a reproducible automated realistic in vitro gastric model
Madalena, Daniel Alexandre Silva; Pinheiro, A. C.; Ramos, Óscar; Vicente, A. A.Despite the development of several anatomical accurate digestion models with dynamic behaviour, few of them can be easily reproduced in the laboratory (i.e., both gastric compartment -GC and peristaltic bands - PB). This way, the present study proposes the development of a reproducible fully automated in vitro gastric model through the application of 3D printing technology to produce both the GC and the perista...
In Situ Forming Silk Sericin-Based Hydrogel: A Novel Wound Healing Biomaterial
Baptista-Silva, Sara; Borges, Sandra; Costa-Pinto, Ana Rita; Costa, Raquel; Amorim, Manuela; Dias, Juliana R.; Ramos, Óscar; Alves, PauloIn situ cross-linked hydrogels have the advantage of effectively fulfilling the wound in its shape and depth. Amongst the new generation of natural-based biopolymers being proposed for wound care and skin regeneration, silk sericin is particularly interesting due to its exceptional properties such as biocompatibility, biodegradability, and antioxidant behavior, among others. In this study, a new enzyme-mediated...
Active whey protein edible films and coatings incorporating Lactobacillus buchn...
Guimarães, Ana Cristina Silva Esperança; Ramos, Óscar; Cerqueira, Miguel; Venâncio, Armando; Abrunhosa, LuísFungal contamination of food is responsible for health issues and food waste. In this work, the incorporation of a lactic acid bacteria (LAB) with antifungal properties (Lactobacillus buchneri UTAD104) into whey protein-based films and coatings was tested for the control of an ochratoxigenic fungi (Penicillium nordicum) in a cheese matrix. The incorporation of L. buchneri cells resulted in thicker films with le...
Calls, colours, shape, and genes: A multi-trait approach to the study of geogra...
Amézquita, Adolfo; Lima, Albertina Pimental; Jehle, Robert; Castellanos, Lina; Ramos, Óscar; Crawford, Andrew J.; Gasser, Herbert; Hödl, WalterEvolutionary divergence in behavioural traits related to mating may represent the initial stage of speciation. Direct selective forces are usually invoked to explain divergence in mate-recognition traits, often neglecting a role for neutral processes or concomitant differentiation in ecological traits. We adopted a multi-trait approach to obtain a deeper understanding of the mechanisms behind allopatric diverge...
