3D tubular constructs based on natural polysaccharides and recombinant polypept...

The development of versatile tubular structures is critical for tissue engineering (TE) applications where vascularization is necessary. This study investigates the fabrication of tubular shaped biomaterials focused on chitosan (CHT) combined with alginate (ALG) and acemannan (ACE), known for their synergistic properties, including physical stability, antibacterial activity, and healing promotion. Translating t...

Development of a tool to assess the compliance of cafeteria menus with the Medi...

Background: The Mediterranean diet (MD) has been considered one of the healthiest dietary patterns, and an excellent model of sustainability. Higher Education food services present an excellent scenario to encourage students healthy eating habits and modulate food choices. The purpose of this work was to develop an index to evaluate MD compliance with cafeteria menus. Methods: Three major axes were considered: ...

Fabrication of biocompatible porous SAIB/silk fibroin scaffolds using ionic liq...

Sucrose acetate isobutyrate (SAIB) is a highly viscous hydrogel and presents many challenges for processing when its application in tissue engineering is envisioned. Herein, is proposed an innovative methodology by processing SAIB with ionic liquids (ILs), combined with silk fibroin (SF), to develop SAIB/SF scaffolds. Fourier Transform Infrared analysis confirmed SF and SAIB presence in the structures and the e...

Photocrosslinked acemannan-based 3D matrices for in vitro cell culture

Current biomedical research has highlighted the potential use of medicinal plant derivatives as advanced suitable biomaterials due to their biological properties. Acemannan (ACE) is the main polysaccharide of Aloe vera (AV) leaves with many reported biological properties, including immunomodulatory activity, antibacterial action, wound healing induction, and cytocompatibility. These properties suggest that ACE ...

Chinese oak tasar silkworm antheraea pernyi silk Proteins: Current strategies a...

Chinese nonmulberry temperate oak tasar/tussah, Antheraea pernyi (Ap) silk is a natural biopolymer that has attracted considerable attention as a biomaterial. The proteinaceous components of Ap silk proteins, namely fbroin and sericin may represent an alternative over mulberry Bombyx mori silk proteins. In fact, the silk fbroin (SF) of Ap is rich in Arginyl-Glycyl-Aspartic acid (RGD) peptides, which facilitate ...

Influência de essências na alimentação artificial energética na atratividade de...

O objetivo desse trabalho foi avaliar a atratividade de diferentes aromas adicionados a alimentação artificial energética de abelhas Apis mellifera. O delineamento experimental usado foi DIC no qual constou de 11 tratamentos e quatro repetições, sendo os tratamentos os aromas tutti-frutte, erva-doce, maracujá, café, baunilha, morango, amarula, menta, cereja, coco e testemunha (sem aroma) e as repetições foram c...

Novel genipin cross-linked chitosan-silk based sponges for the regeneration and...

Development of materials that can interactpositively with tissues is important to regenerative medicine strategies success. Cartilage tissue engineering (TE) scaffolding is a field of continuous evolution, and sponges derived from the combination of polysaccharides and proteins are expected to mimic the naturally occurring environment in the articular cartilage matrix, providing an optimum environment for tissu...

Chitosan/soy-based membranes enhance wound reepithelialization in partial thick...

[Excerpt] Chitosan-based biomaterials proved to have promising characteristics for wound dressing and skin regeneration. In the context of developing new natural-based biomaterials for these applications, chitosan and soybean-based biomaterials were proposed. These materials were shown to be non cytotoxic and to impair human leukocytes activation in vitro. Thus the goal of this study was to evaluate the in vivo...
