The effects of non carious cervical lesions - morphology, load type and restoration - on the biomechanical behavior of maxillary premolars: a finite element analysis

open access: yesBioscience Journal, 2013
The aim of the present study was to analyze the effects of different types of non-carious cervical lesions (NCCLs) and their morphologies in premolars, restored (or not) with composite resin, on the application three occlusal loadings. The hypothesis was

Derivation and characterization of retinal pigment epithelium from urine‐derived iPSCs

open access: yesFEBS Open Bio, EarlyView.
Age‐related macular degeneration causes vision loss via RPE dysfunction and loss. Traditional iPSC therapies rely on invasive biopsies, limiting scalability. Here, we utilize urine‐derived stem cells as an accessible source to generate u‐iPSCs, successfully differentiated into pigmented RPE. This “Urine‐to‐Retina” platform provides a promising path for

Load Priority Modeling for Smart Service Restoration

open access: yesCanadian Journal of Electrical and Computer Engineering, 2017
Enhancing the reliability of distribution systems (DSs) has become a necessity due to society’s dependence on electric power and the high costs associated with service interruptions. One key technique for improving system reliability is to apply efficient power restoration methodologies, which must include a systematic load prioritization method that ...
