Niveles de bioelectricidad en amalgamas con y sin base intermedia

Odontoestomatología
Los nuevos materiales estéticos no han ocasionado el abandono de las obturaciones de amalgama, es por eso que es importante proponer elementos que le den longevidad a las restauraciones.

Unraveling the Morphological and Functional Maturation Mechanisms Underlying Human Neural Development Using iPSCs‐Derived Neuronal Model

Advanced Science, EarlyView.
Using human induced pluripotent stem cells (hiPSCs)‐derived neuronal model, Tian and colleagues reveal that voltage‐gated calcium channels Cav1.2 and Cav1.3, and their mediated calcium ion influx, are essential for early morphogenesis of human neuronal development, while ECEL1 underlies human neuronal functional developmental maturation through CALM3 ...

Comment on “De Novo Reconstruction of 3D Human Facial Images from DNA Sequence”

Advanced Science, EarlyView.
This comment examines AI‐driven DNA‐based facial reconstruction, focusing on the Difface model. While such technologies promise biomedical and forensic applications, they pose significant ethical, legal, and methodological challenges. We emphasize transparency, benchmarking, and rigorous validation to avoid misinterpretation and misuse.

Astrocytic PCBP1 Suppresses Ferroptosis to Restore Glutamatergic Homeostasis and Mitigate Stress‐Induced Depression in Male Mice

Advanced Science, EarlyView.
This study demonstrates that polyC‐RNA‐binding protein 1 (PCBP1) in ventral hippocampal astrocytes modulates depressive‐like behaviors by regulating glutathione peroxidase 4‐mediated ferroptosis and synaptic glutamatergic transmission. PCBP1 overexpression intervention in the chronic unpredictable mild stress model rescues behavioral deficits ...
