Melatonin Alleviates Graft Biliary Fibrosis by Inhibiting VIM+ Cholangiocyte Subcluster via Hypoxia/TGF‐β‐CREM‐VIM Axis

open access: yesAdvanced Science, EarlyView.
Single‐cell RNA sequencing verified the presence of the VIM+ biliary epithelial cell (BEC) in the bile ducts of NAS patients. The hypoxia/TGF‐β‐CREM‐VIM axis mediated phenotypic switch toward VIM+ BEC is validated using a hypoxia/TGF‐β‐stimulated cellular model, a rat liver transplantation model, BEC‐specific Crem conditional knockout rats, and BEC ...

Toward Nano‐Nutritional Medicine: A Remotely Activated Trans‐Vaccenic Acid‐Based Lipid Nanoparticles for Enhancing Immune Checkpoint Blockade Therapy

open access: yesAdvanced Science, EarlyView.
Eutectic mixtures from trans‐vaccenic acid (TVA) and stearic acid, which served as phase‐change material to encapsulate IR780, forming NIR‐responsive nanoparticles. IR780@TVA LNPs induce photothermal therapy and initiate adaptive anti‐tumor immunity.

Targeting Lactate‐Driven Stromal Autophagy via MCT1 Disrupts the Immunosuppressive Niche and Sensitizes Pancreatic Cancer to PD‐1 Blockade

open access: yesAdvanced Science, EarlyView.
Tumor‐derived lactate activates PSCs through MCT1‐mediated Vps34 lactylation and autophagy. These activated PSCs secrete CXCL9/10, upregulating PD‐1 on CD8+ T cells via the CXCR3/STAT3 axis to foster immunosuppression. Disrupting this metabolic crosstalk by targeting MCT1 effectively sensitizes pancreatic cancer to PD‐1 blockade, presenting a promising

Advances in Cancer Immunotherapy for Solid Tumors

open access: yesAdvanced Science, EarlyView.
Cancer immunotherapy for solid tumors is rapidly evolving beyond classical checkpoint blockade toward more precise strategies. Emerging checkpoint targets, bispecific antibodies, antibody–drug conjugate combinations, personalized vaccines, cellular therapies, and engineered cytokines are expanding therapeutic possibilities, while biomarker‐guided ...

Maxillary first molar with two palatal roots: A case report

open access: yesMajallah-i Dānishgāh-i ̒Ulūm-i Pizishkī-i Bābul, 2004
Background and Objective: One of the main reasons of root canal failure is missed canals. Maxillary first molar is one of the most investigated teeth for extra canals.

Endodontic surgical management of failed nonsurgical treatment: Report of a case

open access: yesJournal of Oral Research and Review
The goal of root canal therapy is to eliminate any pulp tissue or bacteria from the canal to promote periapical tissue healing and successful root canal filling. Inadequate root canal shaping and cleaning as well as nonhermetic obturation are two factors
