Influence of sealer and supplementary approach on filling material removal during endodontic retreatment [PDF]

open access: yesBrazilian Oral Research
Both root canal sealer-based and supplementary protocols may influence removal of filling material during endodontic retreatment. Mesial root canals of extracted mandibular molars were prepared using HyFlex EDM 25/.08, and filled with a calcium silicate ...

Nuclear Mechanotransduction Across the Metastatic Cascade: Decoding Spatiotemporal Heterogeneity in Cancer Dissemination

open access: yesAdvanced Science, EarlyView.
Tumor metastasis results from complex interactions between cancer cells and mechanical microenvironments. We propose a “nucleus‐centered, cross‐stage mechanical signal decoding” model, highlighting how nuclear mechanosensors interpret forces at different stages.

Impact of Delayed Completion of Previously Initiated Therapy and Provider Type on Outcomes of Root Canal Treatment [PDF]

open access: yes, 2020
Objective:if the provider type influences long-term outcomes in instances where NSRCT has been previously initiated. The primary purpose of this study was to determine if the period of time between previously initiated therapy and the completion of non ...

Comparison between three glass fiber post cementation techniques [PDF]

open access: yes, 2017
The aim of this experimental study was to compare the traditional cement systems with those of the latest generation, to assess if indeed these could represent of viable substitutes in the cementation of indirect restorations, and in the specific case of

Deciphering the Impact of RAC1‐SPTAN1 in ARPKD Cystogenesis Using Multifaceted Models

open access: yesAdvanced Science, EarlyView.
Distal/connecting tubules expressing SLC8A1 have been suggested as a potential origin of ARPKD cysts. SPTAN1 has been identified as a key molecule in ARPKD cyst formation. Restoring SPTAN1 in PKHD1−/− organoids reduced cyst formation, normalized calcium levels, and decreased RAC1/c‐FOS expression, highlighting SPTAN1's role in ARPKD and the potential ...

Cells Dynamically Adapt Their Nuclear Volumes and Proliferation Rates During Single to Multicellular Transitions

open access: yesAdvanced Science, EarlyView.
It is currently not well understood how cells regulate basic properties, e.g., volume and mechanics within dense multicellular environments like tumors. Here, we show that different cell types of cancer and also normal cells largely decrease their nuclear and cellular volumes in emerging cell clusters and that this is partly driven by cell cycle shifts.

Accurate and Anti‐Interference Control of Computer Vision‐Assisted Light‐Driven Liquid Crystal Elastomer Actuator

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 3, March 2025.
This article introduces a computer vision‐assisted control strategy for light‐driven liquid crystal elastomer actuators. Through negative feedback regulation, the liquid crystal elastomer actuator exhibits accurate and stable bending deformation in complex environments.
