In Vitro Evaluation of Novel Calcium Silicate‐Based and Resin‐Modified Calcium Silicate Materials: Cytocompatibility and Mineralization Potential on Human Dental Pulp Stem Cells for Pulp Repair

open access: yesMicroscopy Research and Technique, EarlyView.
This study demonstrates that Biodentine XP exhibits superior cytocompatibility, promotes odontogenic differentiation, and enhances mineralization in human dental pulp stem cells, supporting its use in regenerative endodontics. Resin‐modified materials showed lower bioactivity, highlighting the importance of material composition in pulp therapy outcomes.

Measurement of Lateral Resolution in Confocal Raman Spectroscopy Using Indium Arsenide Nanowires

open access: yesJournal of Raman Spectroscopy, EarlyView.
Lateral resolution is a key performance parameter for confocal Raman spectroscopy. We propose a protocol using an indium arsenide nanowire reference sample to quantitatively measure the resolution. The suitability of the method has been demonstrated through an international comparison with 15 participants. ABSTRACT Lateral resolution is a key figure of

The Eagle and the Serpent on the Screen, the State as Spectacle in Mexican Cinema [PDF]

open access: yes, 2010
Recent studies of the history of Mexican cinema continue to speak of the complex relations between the state and the film industry, and the most frequently analyzed aspects tend to be the same: the reach and forms of censorship, as well as the financial ...

Mass spectrometry imaging of N‐linked glycans: Fundamentals and recent advances

open access: yesMass Spectrometry Reviews, EarlyView.
Abstract With implications in several medical conditions, N‐linked glycosylation is one of the most important posttranslation modifications present in all living organisms. Due to their nontemplate synthesis, glycan structures are extraordinarily complex and require multiple analytical techniques for complete structural elucidation.

Inconsistent effects of P enrichment and predator presence on food‐web dynamics in a bromeliad system

open access: yesOikos, EarlyView.
Food webs consist of trophic interactions of variable strength. However, it remains challenging to predict how changes in environmental conditions, such as nutrient enrichment, can affect these interactions. In this paper, we propose to integrate food web theory with ecological stoichiometry, which predicts how elemental ratios affect trophic ...
