Comparison of different microalgae biomass typologies used in rotifers enrichme...
de Castro, Daniela; Castaldi, Matthew; Martins, Gil; Santos, Tamara; Pereira, Hugo; Diogo, Patrícia; Varela, João; Gavaia, PauloThe use of enriched rotifers with industrially produced microalgae represents a valuable tool for the enhancement of zebrafishlarval nutrition and increased biological performance. Currently, a monoculture of microalgal species (Nannochloropsis sp.) inform of liquid paste is routinely used for rotifers enrichment for zebrafish larvae feeding; however, the most adequate typology (i.e.,paste or freeze-dried) of the...
Delayed Cutaneous Adverse Reaction of the AstraZeneca COVID-19 Vaccine in a Bre...
Diogo, Patrícia; Correia, Gil; Martins, João B.; Soares, Rui; Palma, Paulo J.; Santos, João Miguel; Gonçalves, TeresaThe ChAdOx1 nCoV-19 vector vaccine (Vaxzevria, AstraZeneca, Cambridge, UK) was developed at Oxford University and is considered safe for the administration in lactating mothers. Nevertheless, as a novel vaccine, there are gaps in the knowledge regarding possible adverse events in breastfeeding infants of vaccinated mothers. This case report provides first-time data on a possible delayed, cutaneous, adverse reac...
Assessment of larval quality of two bivalve species, Crassostrea angulata and C...
Anjos, Catarina; Duarte, Daniel; Diogo, Patrícia; Matias, Domitília; Cabrita, ElsaMarine bivalves are valuable resources, however, some shellfish populations are endangered due to factors such as anthropogenic pressure, pathologies or lack of reproduction synchrony. Portuguese oyster (Crassostrea angulata) and striped venus clam (Chamelea gallina) have high socio-economic value and their endangered natural populations require rehabilitation. Cryopreservation is a valuable method for the pres...
Influence of Blood Contamination on Push-Out Bond Strength of Three Calcium Sil...
Paulo, Cristina Rodrigues; Marques, Joana A.; Sequeira, Diana B.; Diogo, Patrícia; Paiva, Rui; Palma, Paulo J.; Santos, João MiguelA proper bond between root canal filling materials and dentin surface is essential to resist dislodgement and guarantee long-term success. Blood exposure is likely to occur in various clinical situations in which calcium silicate-based materials are used; therefore, it is fundamental to render data concerning the influence of blood on bond strength. The present study aims to evaluate the effect of blood contami...
Tooth Discoloration after Regenerative Endodontic Procedures with Calcium Silic...
Palma, Paulo J.; Marques, Joana A.; Santos, Joana; Falacho, Rui I.; Sequeira, Diana B.; Diogo, Patrícia; Caramelo, Francisco; Ramos, João C.The aim of the present ex vivo study was to assess and compare coronal discoloration induced by four endodontic biomaterials used in regenerative endodontic procedures (REPs). Root resection was executed horizontally, 2 mm apical to the cementoenamel junction, in all fifty-four teeth. After accessing the pulp chamber, specimens were randomly divided in groups and filled with either saline solution or blood, fol...
Does Apical Papilla Survive and Develop in Apical Periodontitis Presence after ...
Palma, Paulo J.; Martins, João; Diogo, Patrícia; Sequeira, Diana B.; Diogenes, Aníbal; Santos, João MiguelRegenerative endodontic procedures (REPs) have emerged as a treatment option for immature necrotic teeth to allow the reestablishment of a newly formed vital tissue and enable continued root development. The apical papilla stem cells (SCAPs) play an important role in physiologic root development and may also contribute to further root development during REPs. The goal of these case reports is to show evidence o...
An Insight into Advanced Approaches for Photosensitizer Optimization in Endodon...
Diogo, Patrícia; Faustino, M. F. Amparo; Neves, Graça M. P. M. S.; Palma, Paulo J.; Baptista, Isabel P.; Gonçalves, Teresa; Santos, João MiguelApical periodontitis is a biofilm-mediated disease; therefore, an antimicrobial approach is essential to cure or prevent its development. In the quest for efficient strategies to achieve this objective, antimicrobial photodynamic therapy (aPDT) has emerged as an alternative to classical endodontic irrigation solutions and antibiotics. The aim of the present critical review is to summarize the available evidence...
Is the chlorophyll derivative Zn(II)e6Me a good photosensitizer to be used in r...
Diogo, Patrícia; Mota, Marta; Fernandes, Chantal; Sequeira, Diana; Palma, Paulo; Caramelo, Francisco; Neves, M. Graça P. M. S.; Faustino, M Amparo F.The aim of this study was to assess antimicrobial efficacy and cytotoxic outcomes of a chlorophyll based photosensitizer (PS) Zn(II)chlorin e6 methyl ester (Zn(II)e6Me), when applied to human dentin discs and root blocks infected with 48 h biofilms. The results were compared with the ones obtained with FotoSan® (commercial Toluidine Blue O formulation) and 3% sodium hypochlorite (NaOCl).
Antimicrobial Photodynamic Therapy against Endodontic Enterococcus faecalis and...
Diogo, Patrícia; Fernandes, Chantal; Caramelo, Francisco; Mota, Marta; Miranda, Isabel M.; Faustino, M. A. F.; Neves, M. G. P. M. S.Endodontic biofilms eradication from the infected root canal system remains as the primary focus in endodontic field. In this study, it was assessed the efficacy of antimicrobial Photodynamic Therapy (aPDT) with the Zn(II)chlorin e6 methyl ester (Zn(II)e6Me) activated by red light against monospecies and mixed biofilms of Enterococcus faecalis and Candida albicans. The results were compared with the ones obtain...
