A Rare Root Canal Configuration of Maxillary Second Molar: A Case Report

Case Reports in Dentistry, 2012
A thorough knowledge of root canal morphology is a prerequisite for the endodontic therapy. The maxillary molars, especially the second molars, have the most complicated root canal system in permanent dentition.

KRAS Withdrawal in Cholangiocarcinoma Leads to Immune Infiltration and Tumor Regression

Advanced Science, EarlyView.
Cholangiocarcinoma (CCA) driven by oncogenic KRAS depends on its continuous activation for tumor maintenance. Using a conditional KRAS model, the authors show that turning off KRAS triggers rapid tumor regression accompanied by immune cell infiltration and cytokine release. The findings uncover a KRAS–senescence–immune signaling axis and highlight KRAS

Connexin 26 Functions as a Direct Transcriptional Regulator During the Cochlea Development

Advanced Science, EarlyView.
Connexin26 can not only form intercellular channels that mediate rapid communication on the cell membrane, but also enter the nucleus as a transcription factor to directly regulate the transcription of nuclear genes. In the developing cochlea, Cx26 can control the maturation of the molecular scissor ADAM10 by regulating the transcription of TspanC8 ...

Real‐Time In Vivo Cellular‐Level Imaging During Puncture

Advanced Science, EarlyView.
We present an artificial‐intelligence‐empowered integrative‐light‐field microendoscopy (AIM) needle that delivers real‐time in vivo, diffraction‐limited cellular‐level imaging during puncture and visualizes layered microstructures along the needle path. As a microscopic complement to CT/ultrasound, it improves sampling localization and adds preliminary

Advanced Human Immune Cell‐Organoid Co‐Cultures for Functional Testing of Cancer Nanovaccines

Advanced Science, EarlyView.
Pancreatic ductal adenocarcinoma remains difficult to treat. We establish an organoid–immune co‐culture using patient‐derived organoids and matched T‐cells to assess cancer vaccines. A mesothelin‐targeted nanovaccine activates antigen‐specific T‐cells, increases IFN‐γ, and targets MSLN+ organoids.

Micro-computed tomographic evaluation of root and canal anatomy of maxillary first premolars in Iraqi sub-population

Scientific Reports
Successful root canal treatment requires a thorough understanding of root canal morphology. This study investigated the root canal morphology and the fine anatomical characteristics of maxillary first premolars in an Iraqi sub-population using micro ...

Elevator‐Like Hollow Channels in Porous Scaffolds Accelerate Vascularized Bone Regeneration via NETs‐Fibrin‐Mediated Macrophage Recruitment

Advanced Science, EarlyView.
This study demonstrates that how hollow‐channel scaffolds promote vascularized bone regeneration via an immunomodulatory mechanism. The channel structures facilitate the formation of a neutrophil extracellular traps‐fibrin scaffold that recruits vascular endothelial growth factor A (VEGF‐A)‐secreting M2 macrophages to drive angiogenesis. Combining this

S3RL: Enhancing Spatial Single‐Cell Transcriptomics With Separable Representation Learning

Advanced Science, EarlyView.
Separable Spatial Representation Learning (S3RL) is introduced to enhance the reconstruction of spatial transcriptomic landscapes by disentangling spatial structure and gene expression semantics. By integrating multimodal inputs with graph‐based representation learning and hyperspherical prototype modeling, S3RL enables high‐fidelity spatial domain ...
