In vitro optimization of photobiomodulation and ultrasound stimulation protocol...
Monteiro, Francisca; Oliveira, Sofia; Marques, Carlos; Papadimitriou, Georgia; Silva, Joana M.; Padrão, Jorge; Sotiropoulos, Ioannis; Catarino, SusanaThe effectiveness of transcranial photobiomodulation (tPBM) and ultrasound stimulation (tUS) to mitigate different neuropathological mechanisms and stimulate neuroprotective responses has been vastly demonstrated in preclinical disease models. However, the translation into clinics is still suboptimal, revealing the need for more solid basic research to ascertain the most effective stimulation parameters to modu...
Influence of ultrasound stimulation on the viability, proliferation and protein...
Pascoal, Selma; Oliveira, Sofia; Monteiro, Francisca; Padrão, Jorge; Costa, Rita; Zille, Andrea; Catarino, Susana Oliveira; Silva, Filipe S.Among the adjunctive procedures to accelerate orthodontic tooth movement (OTM), ultrasound (US) is a nonsurgical form of mechanical stimulus that has been explored as an alternative to the currently available treatments. This study aimed to clarify the role of US in OTM by exploring different stimulation parameters and their effects on the biological responses of cells involved in OTM. Human fetal osteoblasts a...
Developing optical mimicking phantoms of the head tissues – a new approach for ...
Fernandes, Filipa; Silva, Filipe S.; Sousa,Nuno; Catarino, Susana Oliveira; Carvalho, Óscar Samuel NovaisTranscranial photobiomodulation (tPBM) has gained relevance in the recent decade, due to positive results in clinical trials for several neurological pathologies (e.g., stroke, traumatic brain injury, dementia related diseased). Nonetheless, the uncertainty around the ideal light parameters causes some resistance in the incorporation of this therapy into mainstream practice [1]. To establish optimal stimulation...
Optimization of a photobiomodulation protocol to improve the cell viability, pr...
Gonçalves, Aline; Monteiro, Francisca Machado; Oliveira, Sofia; Costa, Inês; Catarino, Susana Oliveira; Carvalho, Óscar Samuel Novais; Padrão, JorgeNumerous pieces of evidence have supported the therapeutic potential of photobiomodulation (PBM) to modulate bone remodeling on mechanically stimulated teeth, proving PBM's ability to be used as a coadjuvant treatment to accelerate orthodontic tooth movement (OTM). However, there are still uncertainty and discourse around the optimal PBM protocols, which hampers its optimal and consolidated clinical applicabili...
Assessing the influence of ultrasound stimulation parameters in neuronal-like c...
Monteiro, Francisca; Oliveira, Sofia; Catarino, Susana Oliveira; Sotiropoulos, Ioannis; Carvalho, Óscar Samuel Novais; Silva, Filipe S.Alzheimer’s disease (AD) is a neurodegenerative disorder that represents the most common cause of dementia, but recent efforts to develop effective pharmacological treatments have been disappointing. However, non-drug solutions have been proposed to block disease progression and alleviate clinical symptoms, demonstrating promising results. Transcranial ultrasound stimulation is at the forefront of alternative t...
Microscopic inspection of the adhesive interface of composite onlays after ceme...
Magalhães, Tiago; Fidalgo-Pereira, Rita; Torres, Orlanda; Carvalho, Óscar; Silva, Filipe S.; Henriques, Bruno; Özcan, Mutlu; Souza, Júlio C. M.Purpose: This study aimed to assess the layer thickness and microstructure of traditional resin-matrix cements and flowable resin-matrix composites at dentin and enamel to composite onlay interfaces after cementation on low loading magnitude. Materials and Methods: Twenty teeth were prepared and conditioned with an adhesive system for restoration with resin-matrix composite onlays manufactured by CAD-CAM. On ce...
A scoping review on the polymerization of resin-matrix cements used in restorat...
Fidalgo-Pereira, Rita; Torres, Orlanda; Carvalho, Óscar; Silva, Filipe S.; Catarino, Susana O.; Özcan, Mutlu; Souza, Júlio C. M.In dentistry, clinicians mainly use dual-cured or light-cured resin-matrix cements to achieve a proper polymerization of the organic matrix leading to enhanced physical properties of the cement. However, several parameters can affect the polymerization of resin-matrix cements. The main aim of the present study was to perform a scoping review on the degree of conversion (DC) of the organic matrix, the polymeriza...
Inconsistency in shoulder arthrometers for measuring glenohumeral joint laxity:...
Gomes, Eluana; Andrade, Renato; Valente, Cristina; Santos, J. Victor; Nunes, Jóni; Carvalho, Óscar Samuel Novais; Correlo, V. M.; Silva, Filipe S.There is no consensus on how to measure shoulder joint laxity and results reported in the literature are not well systematized for the available shoulder arthrometer devices. This systematic review aims to summarize the results of currently available shoulder arthrometers for measuring glenohumeral laxity in individuals with healthy or injured shoulders. Searches were conducted on the PubMed, EMBASE, and Web of...

Influence of micro-textures on cutting insert heat dissipation
Rosas, José; Lopes, Hernani; Guimarães, Bruno; Piloto, P.A.G.; Miranda, Georgina; Silva, Filipe S.; Paiva, Olga C.Metal machining is one of the most important manufacturing processes in today’s pro- duction sector. The tools used in machining have been developed over the years to improve their performance, by reducing the cutting forces, the friction coefficient, and the heat generated during the cutting process. Several cooling systems have emerged as an effective way to remove the excessive heat generated from the chip-t...
