      Concave surfaces have shown to promote bone regeneration in vivo. However, bone scaffolds obtained by direct ink writing, one of the most promising approaches for the fabrication of personalized bone grafts, consist mostly ...

    • ß2-adrenergic stimulation potentiates spontaneous calcium release by increasing signal mass and co-activation of ryanodine receptor clusters 

      Nolla Colomer, Carme; Casabella Ramón, Sergi; Jiménez Sábado, Verónica; Vallmitjana Lees, Alexander; Tarifa Lora, Carmen; Herraiz Martínez, Adela; Montiel Dacosta, José Antonio; Cinca Cuscullola, Juan Maria; Benítez Iglesias, Raúl; Hove-Madsen, Leif (2022-04-13)
      Article
      Accés obert
      Aims It is unknown how ß-adrenergic stimulation affects calcium dynamics in individual RyR2 clusters and leads to the induction of spontaneous calcium waves. To address this, we analysed spontaneous calcium release ...

    • Hydrothermal processing of 3D-printed calcium phosphate scaffolds enhances bone formation in vivo: a comparison with biomimetic treatment 

      Raymond Llorens, Santiago; Bonany Mariñosa, Mar; Lehmann, Cyril; Thorel, Emilie; Benítez Iglesias, Raúl; Franch Serracanta, Jordi; Canal Barnils, Cristina; Ginebra Molins, Maria Pau (Elsevier, 2021-11-01)

      Hydrothermal (H) processes accelerate the hydrolysis reaction of a-tricalcium phosphate (a-TCP) compared to the long-established biomimetic (B) treatments. They are of special interest for patient-specific 3D-printed bone ...

    • Comparison between experimental digital image processing and numerical methods for stress analysis in dental implants with different restorative materials 

      Cantó Navés, Oriol; Marimon Serra, Xavier; Ferrer Ballester, Miquel; Cabratosa Termes, Josep (Elsevier, 2021-01-01)
      Article
      Accés restringit per política de l'editorial
      The aim of this study is to evaluate the stresses transferred to peri-implant areas from single implants restored with different restorative materials and subjected to a static vertical load with low eccentricity. A total ...

    • Influence of sex on intracellular calcium homoeostasis in patients with atrial fibrillation 

      Herraiz Martínez, Adela; Tarifa Lora, Carmen; Jiménez Sábado, Verónica; Llach Martínez, Ana; Colino-Lage, Hildegard; Nolla Colomer, Carme; Benítez Iglesias, Raúl; Ciruela, Francisco; Cinca Cuscullola, Juan Maria; Hove-Madsen, Leif (2021-03-31)
      Article
      Accés obert
      Aims Atrial fibrillation (AF) has been associated with intracellular calcium disturbances in human atrial myocytes, but little is known about the potential influence of sex and we here aimed to address this issue. Methods ...

    • A 3D finite element analysis model of single implant-supported prosthesis under dynamic impact loading for evaluation of stress in the crown, abutment and cortical bone using different rehabilitation materials
