Parvalbumin Interneuron‐Dependent Hippocampal Neurogenesis Evoked by Prolonged Rhythmic Light Flicker

Advanced Science, EarlyView.
This study demonstrates that prolonged rhythmic 40 Hz light flicker enhances spatial learning by stimulating PV interneuron‐dependent neurogenesis. The light flicker selectively activates PV interneurons, which enhances GABAergic support for the integration of immature neurons in the adult dentate gyrus.

Cellular Adaptation to Mechanical Stress Emerges via Cell Shrinkage Triggered by Nonlinear Calcium Elevation

Advanced Science, EarlyView.
Here, a decision‐making mechanism underlying mechanical adaptation is demonstrated. This study demonstrates that cellular adaptation to mechanical stress can be induced by applying low‐amplitude stretch to cells. When the stretch reaches a critical amplitude threshold, it triggers Ca2⁺‐dependent positive feedback, which induces cholesterol efflux and ...

A Human Immuno‐Lung Organoid Model to Study Macrophage‐Mediated Lung Cell Senescence Upon SARS‐CoV‐2 Infection

Advanced Science, EarlyView.
Immuno‐lung organoids are developed and used spatial transcriptomics to uncover how proinflammatory macrophages drive lung cell senescence via the THBS1–(ITGA3+ITGB1) axis in COVID‐19. To ensure broad accessibility, LungSpatialDB is created, an AI‐powered data portal, enabling intuitive exploration of spatial data and biological insights through ...

A retrospective study of combined fixed-removable reconstructions with their analysis of failures.

Journal of Oral Rehabilitation, 1998
The survival rate and the reasons for failures of 130 combined fixed-removable reconstructions (CFR), incorporated in 112 patients, were assessed. Each CFR reconstruction was classified depending on its attachments: 76 reconstructions were attached with ...

Advances in Dental Materials [PDF]

Dental Clinics of North America, 2011
The use of materials to rehabilitate tooth structures is constantly changing. Over the past decade, newer material processing techniques and technologies have significantly improved the dependability and predictability of dental material for clinicians. The greatest obstacle, however, is in choosing the right combination for continued success.

Genotoxicity of dental materials

Mutation Research/Genetic Toxicology, 1996
This study was performed to characterize the (possible) DNA-damaging properties of dental materials and to identify specific compounds that contribute to this genotoxicity. For screening, three tests that assay for different aspects of genotoxicity (i) the bacterial umu-test; (ii) the eucaryotic DNA synthesis inhibition test; and (iii) the in vivo ...
