Dynamic Navigation-Assisted Calcified Root Canal Therapy In Maxillary Incisor

open access: yesInternational Dental Journal
Introduction: Calcified root canal represents a troublesome problem in root canal therapy. Especially for diseased teeth accompanied by periapical periodontitis, whether root canal could be successfully dredged is key for curative effects.

Ammonia Detoxification Inhibits Liver Metastasis by Reshaping Hepatic Microenvironment

open access: yesAdvanced Science, EarlyView.
Liver metastasis diverts aspartate into hyperactive pyrimidine synthesis, disrupting urea cycling and causing pathogenic ammonia accumulation. Ammonia dually reprograms the microenvironment by: (1) activating hepatic stellate cells (HSCs) into pro‐fibrotic metastasis‐associated fibroblasts (MAFs), and (2) suppressing anti‐tumor monocytes/macrophages ...

Root and canal morphology of mandibular first premolars in a Polish population: A cone-beam computed tomography study

open access: yesFolia Morphologica
BACKGROUND: This study aimed to assess the root and canal morphology of mandibular first premolars in a Polish population using cone-beam computed tomography (CBCT) and to correlate the findings with tooth position and patient gender.

Vorinostat Potentiates Chemoimmunotherapy in Immune‐Enriched Pancreatic Cancer

open access: yesAdvanced Science, EarlyView.
Immune‐enriched pancreatic cancer does not confer a significant survival advantage. SAHA sensitizes these “hot” tumors to chemoimmunotherapy by disrupting a FASN/PARP9‐driven “metabolic trap” and enhancing CD8+ T cell function. A CD8high/FASNhigh/PARP9high signature identifies patients who are most likely to benefit from the “gemcitabine‐nivolumab‐SAHA”

Leveraging Artificial Intelligence and Large Language Models for Cancer Immunotherapy

open access: yesAdvanced Science, EarlyView.
Cancer immunotherapy faces challenges in predicting treatment responses and understanding resistance mechanisms. Artificial intelligence (AI) and machine learning (ML) offer powerful solutions for cancer immunotherapy in patient stratification, biomarker discovery, treatment strategy optimization, and foundation model development.

Treatment strategy analysis and prevalence of root canal variation of maxillary second molars from a native Chinese population

open access: yes口腔疾病防治
The anatomical morphology of root canal systems in maxillary second molars (MSMs) is complex and shows diverse variations, which leads to challenging root canal treatments that could end in failure.

Unpredictable Root Canal Morphology: Expect the Unexpected

open access: yesAdvances in Human Biology, 2015
Background: A maxillary first molar with more than four canals is an interesting example of anatomic variations, especially when two of these canals are detected, with separate apical foramen in the distal root.

The Host Cell Factor Phosphatase‐2A Subunit PR130 Restricts Replication of Herpes Simplex Virus Type‐1

open access: yesAdvanced Science, EarlyView.
Molecular, genetic, virological, and biochemical analysis in combination with global proteome and phosphoproteome profiling and functional assays were applied to study the role of PR130 in the context of HSV‐1 replication. The observations reveal that host‐intrinsic mechanisms regulate HSV‐1 replication and highlight PR130 as a susceptibility factor of

Two Rooted Mandibular First Molar with Three Distal Canals - A Case Report

open access: yesAdvances in Human Biology, 2014
Background: The Mandibular first molar is the tooth that requires root canal treatment most often. It usually has two roots with two canals mesially and one or two canals distally.

Cells Dynamically Adapt Their Nuclear Volumes and Proliferation Rates During Single to Multicellular Transitions

open access: yesAdvanced Science, Volume 13, Issue 31, 4 June 2026.
It is currently not well understood how cells regulate basic properties, e.g., volume and mechanics within dense multicellular environments like tumors. Here, we show that different cell types of cancer and also normal cells largely decrease their nuclear and cellular volumes in emerging cell clusters and that this is partly driven by cell cycle shifts.
