Article Abstract
The relationships between clonal architecture and functional heterogeneity in acute myeloid leukemia (AML) samples are not yet clear. We used targeted sequencing to track AML subclones identified by whole-genome sequencing using a variety of experimental approaches. We found that virtually all AML subclones trafficked from the marrow to the peripheral blood, but some were enriched in specific cell populations. Subclones showed variable engraftment potential in immunodeficient mice. Xenografts were predominantly comprised of a single genetically defined subclone, but there was no predictable relationship between the engrafting subclone and the evolutionary hierarchy of the leukemia. These data demonstrate the importance of integrating genetic and functional data in studies of primary cancer samples, both in xenograft models and in patients.

Social Participation and Depressive Symptoms Among Older Adults.

Importance: Previous studies have suggested that social participation helps prevent depression among older adults. However, evidence is lacking about whether the preventive benefits vary among individuals and who would benefit most.
Objective: To examine the sociodemographic, behavioral, and health-related heterogeneity in the association between social participation and depressive symptoms among older adults and to identify the individual characteristics among older adults expected to benefit the most from social participation.
Donor site healing in follicular unit extraction hair transplantation: current evidence, cellular mechanisms, and future research directions.

Arencibia Clinic, San Sebastian, Spain.
Follicular unit extraction (FUE) has become a leading technique in hair transplantation, yet optimal management of the donor area remains a clinical challenge. This systematic review analyzes intraoperative and postoperative interventions applied to the donor area in FUE hair transplantation, with a focus on both clinical outcomes and the cellular and molecular mechanisms involved in tissue repair, inflammatory response, and regenerative processes. A comprehensive literature search was conducted in PubMed and EMBASE (January 2000-June 2025), identifying clinical studies that evaluated donor area treatments and reported outcomes related to healing, inflammation, infection, and patient satisfaction.

Bacterial persisters are a subpopulation of cells that exhibit a transient non-susceptible phenotype in the presence of bactericidal antibiotic concentrations. This phenotype can lead to the survival and regrowth of bacteria after treatment, resulting in relapse of infections. It is also a contributing factor to antibacterial resistance.

Accurate tumor mutation burden (TMB) quantification is critical for immunotherapy stratification, yet remains challenging due to variability across sequencing platforms, tumor heterogeneity, and variant calling pipelines. Here, we introduce TMBquant, an explainable AI-powered caller designed to optimize TMB estimation through dynamic feature selection, ensemble learning, and automated strategy adaptation. Built upon the H2O AutoML framework, TMBquant integrates variant features, minimizes classification errors, and enhances both accuracy and stability across diverse datasets.

In this study, a one-pot hydrothermal synthesis method was used to synthesize a novel gold-yttrium trimesic acid metal-organic framework (Au-Y-TMA MOF), demonstrating significant improvements over conventional single-metal MOFs, that is, yttrium trimesic acid (Y-TMA), in both supercapacitor applications and electrochemical antibiotic detection. The X-ray diffraction patterns of Au-Y-TMA confirmed the presence and impact of Au in the Y-TMA matrix, while field emission scanning electron microscopy (FE-SEM) images revealed a heterogeneous combination of gold nanoparticles (AuNPs) and Y-TMA, suggesting a nonuniform distribution and possible interaction. The developed half-cell supercapacitor exhibited a remarkable capacitance value of 1836 F/g at a current density of 5 A/g by galvanostatic charging-discharging (GCD) measurement.
