UV-crosslinked biomaterials: Functionalized polyethylene glycol for tissue adhe...

Surgeons around the world face the challenge of effectively and securely treat acute wounds. The most used techniques used to reestablish proper tissue continuity and promote healing comprise surgical tape strips and wound suturing or stapling. However, these have different limitations associated, like additional tissue trauma and patient discomfort. Tissue adhesives have emerged as a promising alternative to t...

A massificação e democratização da Educação Doutoral na encruzilhada entre a eq...

Nas últimas décadas, têm sido notórios, em Portugal e à escala global, processos de massificação e democratização da Educação Doutoral (ED) que promovem a abertura a doutorandos/as com características diversas, incluindo doutorandos/as não tradicionais, embora se reconheça a persistência de limitações à massificação e democratização do acesso e do valor do grau. Este estudo qualitativo explora as (des)continuid...

Are heterogeinity and conflicting preferences no longer a problem? Personality-...

The complexity associated with groups of tourists led to the emergence of Group Recommender Systems (GRS) for tourism. But if generating recommendations for small groups is a complex task, to provide them to large and occasional groups is even more. This complexity is especially due to the group's heterogeinity, conflicting preferences, the information overload found on the internet and the tourists’ different ...

IgA Mediated Anti-Glomerular Basement Membrane Disease with Associated Circulat...

Anti-glomerular basement membrane (anti-GBM) disease is an aggressive small vessel vasculitis usually mediated by IgG autoantibodies. We describe the case of a 73-year-old male with rapidly progressive renal failure that was diagnosed with IgA mediated anti-GBM disease associated with circulating anti-neutrophil cytoplasm antibodies (ANCA), where the diagnosis was established on kidney biopsy by detecting linea...

Renewable Photo-Cross-Linkable Polyester-Based Biomaterials: Synthesis, Charact...

TThe present work consist of the synthesis of photo-crosslinkable materials, based on unsaturated polyesters (UPs), synthesized from biobased monomers from renewable sources such as itaconic acid and 1,4- butanediol. The UPs were characterized to assess the influence of polycondensation reaction temperature and cross-linking time on their final properties. For this purpose, different UV irradiation exposure per...

Calcium Polystyrene Sulfonate-Induced Colitis: Advanced Characterization of Cry...

Classical potassium binders are used in the treatment of hyperkalemia and are widely associated with gastrointestinal side effects, with crystal colonic injury being rare but potentially fatal. In this report, we describe the case of an 82-year-old male with hyperkalemia and calcium polystyrene sulfonate crystal-associated colonic necrosis. Traditionally, this diagnosis has relied on the examination of crystal ...

Preparation of Gel Forming Polymer-Based Sprays for First Aid Care of Skin Inju...

Currently, there are several types of materials for the treatment of wounds, burns, and other topical injuries available on the market. The most used are gauzes and compresses due to their fluid absorption capacity; however, these materials adhere to the surface of the lesions, which can lead to further bleeding and tissue damage upon removal. In the present study, the development of a polymer-based gel that ca...

Lignin Recovery from Black Liquor Using Integrated UF/NF Processes and Economic...

Lignin is a polyphenolic biopolymer present in large amounts in black liquor (BL). This work investigated the recovery of lignin from BL (pre-filtered by ultrafiltration (UF)) by nanofiltration (NF). For the NF tests, laboratory-made mixed matrix membrane (MMM) prepared with 0.1% activated carbon (AC) nanoparticles were used in crossflow filtration mode. The effect of pressure (6-15 bar) and volume reduction (V...
