Cancers evolve not only through the acquisition and clonal transmission of somatic mutations but also by epigenetic mechanisms that modify cell phenotype. Here, we use histology-guided and spatial transcriptomics to characterize hepatoblastoma, a childhood liver cancer that exhibits significant histologic and proliferative heterogeneity despite clonal activating mutations in the Wnt/β-catenin pathway. Highly proliferative regions with embryonal histology show high expression of Wnt target genes, the embryonic biliary transcription factor SOX4, and striking focal expression of the growth factor FGF19.

High-temperature Tl decay clarifies Pb dating in early Solar System.

Nature

November 2024

GSI Helmholtzzentrum für Schwerionenforschung GmbH, Darmstadt, Germany.

Article Synopsis
  • Radioactive nuclei that live for millions of years help us understand the Sun's formation and the nucleosynthesis happening when it was born, with lead (Pb) being a key example.
  • Recent measurements of the weak decay of ionized thallium (Tl) provided a more accurate half-life, which was found to be 4.7 times longer than previously thought, thus reducing uncertainty in our calculations.
  • Using these improved decay rates, researchers calculated lead yields in asymptotic giant branch (AGB) stars, confirmed isolation times for solar material, and validated the theory that the Sun formed in a long-lived molecular cloud.

Non-adherence to antipsychotic medications is a commonly recognized problem that can lead to lack of follow-up for patients with schizophrenia spectrum disorders, increasing risk for psychotic symptoms, hospitalizations, and decreased quality of life. We conducted a secondary data analysis of electronic health record data of patients with schizophrenia spectrum disorders ( = 1,341) in Central Florida to explore relationships between geographic access to mental healthcare facilities, socioeconomic factors, and follow-up visits, and whether these conditions contributed to adherence over 1 years' time. Using Geographic Information Systems among six mental health facilities, spatial analysis and logistic regression indicated that patients had 27.

Background: Choledocholithiasis in children is commonly managed with an "endoscopy-first" (EF) strategy (endoscopic retrograde cholangiopancreatography (ERCP) followed by laparoscopic cholecystectomy (LC)). Because ERCP availability is often limited at the end of the week (EoW), we hypothesized that a "surgery-first" (SF) approach (LC with intraoperative cholangiogram (IOC) ± transcystic laparoscopic common bile exploration (LCBDE)) would decrease length of stay (LOS) and time to definitive intervention (TTDI).

Methods: A multicenter, retrospective cohort study was conducted on pediatric patients from 2018 to 2023 with suspected choledocholithiasis.
