Co‐activation of Selective Nicotinic Acetylcholine Receptor Subtypes Is Required for Neuroprotection against Alzheimer's Disease

open access: yesAdvanced Science, EarlyView.
ABSTRACT Beta‐amyloid peptide (Aβ)‐induced suppression of hippocampal GABAergic interneuron activity drives hyperexcitability, amyloid pathology, and cognitive impairment in Alzheimer's disease (AD), suggesting that enhancing hippocampal inhibition may be protective.

Astrocytes Coordinate Neurovascular Coupling During Prolonged Sensory Demand via AQP4/TRPA1/BEST1/D‐Serine Signaling

open access: yesAdvanced Science, EarlyView.
Neuronal activation leads to astrocytic transient volume changes, activating transient receptor potential ankyrin 1 (TRPA1) channels, leading to Ca2+ influx. Activation of TRPA1 causes the release of D‐serine through BEST1. Finally, the augmented extracellular levels of D‐serine boost neuronal activity by binding GluN1‐containing NMDARs, leading to CBV

Conventional impression and optical impression for dental implant : presentation of current techniques and comparison

open access: yes, 2017
L'empreinte implantaire est le premier maillon dans la chaîne de réalisation de la prothèse supra-implantaire. C’est l'étape la plus déterminante dans le succès de la fabrication des supra structures implantaires fixes et donc de leur pérennité. L’empreinte implantaire nécessite l'utilisation d'un dispositif de « transfert » qui va venir se connecter à

Molecular Landscapes of Tumor Dormancy in Gynecologic Malignancies: From Survival Mechanisms to Precision Interception

open access: yesAdvanced Science, EarlyView.
This Review outlines the biological framework of entry, maintenance, and awakening in dormant minimal residual disease across gynecologic cancers. By mapping critical biological dependencies—from metabolic plasticity to microenvironment interactions—it evaluates novel interception concepts and presents a translational framework combining single‐cell ...
