La investigación en ciencias de la salud. El rol de los comités de ética en odontología Research in health sciences. The role of ethics committees in dentristry

open access: yesRevista de la Asociación Odontológica Argentina, 2019
Resumen Desde su nacimiento en los años setenta, la bioética ha entrado de forma definitiva en el mundo de las ciencias de la salud. Su papel es multifacético, pero es trascendental en cuanto a los pilares normativos y éticos necesarios en la ...

Two‐Dimensional Conjugated Metal Organic Frameworks with Dual Metal Catalytic Active Sites Enhance POD Activity for Antibacterial Treatment

open access: yesAdvanced Science, EarlyView.
A new class of Cu, Ni bimetallic 2D cMOF (CuNi‐HHTP 2D cMOF) featuring dual catalytic sites and high delocalized electronic structure for boosting POD performance. The CuNi‐HHTP 2D‐cMOF enhances the conversion kinetics of H2O2 to ROS, which subsequently enhances antibacterial activity and accelerates the healing of oral ulcers, with macroscopic wound ...

Human Dental Pulp Stem Cell Secretome Restores Ischemic Stroke–Impaired Motor and Cognitive Functions by Reprogramming Redox and Inflammatory Signaling

open access: yesAdvanced Science, EarlyView.
Human dental pulp stem cell secretome emerges as a cell‐free therapeutic strategy for ischemic stroke by reprogramming redox and inflammatory signaling. hDPSC secretome‐derived antioxidant and immunomodulatory factors suppress the TLR4–NOX–ROS–NF‐κB axis, reduce microglial inflammatory responses and apoptosis, and promote neurogenesis, angiogenesis ...

Morphology of Denisovan molars: problems of taxon identification in the context of genetic data [PDF]

open access: yesВестник археологии, антропологии и этнографии
Attempts to analyse fragmentary specimens of Denisovan remains in conjunction with archaeological and genetic data may be a useful experience in the search for taxonomically valuable traits.

Ion‐Driven Regulation of Ca2+ Flow by Ti/Zn Composite Activates ERK/MAPK Signaling and Maintains Mitochondrial Homeostasis to Promote Macrophage‐Mediated Bone Regeneration

open access: yesAdvanced Science, EarlyView.
A 3D‐printed interpenetrating Ti/Zn composite enables sustained Zn2+ release to regulate intracellular Ca2+ redistribution, preserve mitochondrial homeostasis, activate ERK/MAPK signaling, and promote M2 macrophage polarization, thereby enhancing osteoimmune‐mediated bone regeneration and peri‐implant osseointegration.

Performance Estimation and Ex Vivo Validation of Untethered Magnetic Robots in Soft Tissue

open access: yesAdvanced Science, EarlyView.
This study presents an empirical model that quantitatively predicts the step‐out frequency of screw‐type untethered magnetic robots (UMRs) in soft viscoelastic environments, including ex vivo brain tissue. By integrating key parameters into a dimensionless framework, the model enables estimation of robot performance across a range of biological ...

Intranasal Delivery of Gallium–Quercetin Nanoparticles for Multi‐Target Ferroptosis Inhibition in Parkinson's Disease

open access: yesAdvanced Science, EarlyView.
Leveraging the chemical similarity between Ga3+ and Fe3+ as well as the antioxidant properties of quercetin, gallium–quercetin nanoparticles (GQNPs) were prepared to integrate iron homeostasis regulation, oxidative stress suppression, and mitochondrial protection for multi‐target ferroptosis inhibition in Parkinson's Disease.

Interaction Between Operator and Assistant Certification Is Associated With Local Recurrence After Laparoscopic Rectal Cancer Surgery: An Ancillary Analysis of the EnSSURE Study

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
A significant synergistic interaction between operator and assistant certification was associated with a lower risk of local recurrence after laparoscopic rectal cancer surgery. Patients treated by both ESSQS‐qualified operators and assistants had the lowest risk of local recurrence, whereas a single qualification alone was not associated with a ...
