CONCLUSIONS: Modern radiotherapy techniques allow safe delivery of high radiation doses for LAPC. SBRT provides excellent and durable local control with low rates of treatment-related grades ≥3 toxicities.

CONCLUSIONS: The coupled platform we have developed has enabled direct volumetric imaging of the dynamics of pathogen binding and concomitant recruitment of membrane receptors on live cells. The platform closes a critical gap between optically sectioned fluorescence and label-free 3D phase imaging and can be adapted to other receptor-ligand systems that would benefit from correlated structural and functional insights.

MOTIVATION: Segmentation and automated genome annotation (SAGA) techniques, such as Segway and ChromHMM, assign labels to every part of the genome, identifying similar patterns across multiple genomic input signals. Inferring biological meaning in these patterns remains challenging. Doing so requires a time-consuming process of manually downloading reference data, running multiple analysis methods, and interpreting many individual results.

Long-term hematopoietic stem cells (LT-HSC) maintain lifelong hematopoiesis while preserving the stem cell compartment through self-renewal. The human LT-HSC compartment is molecularly and functionally heterogeneous and also varies across ontogeny. Dissecting the molecular basis for this variation is impeded by the paucity of immunophenotypic markers to resolve LT-HSC heterogeneity. Here, we identified ATPase plasma membrane calcium transporting 1 (ATP2B1/PMCA1) as a cell surface marker that is...

Despite most acute myeloid leukemia (AML) patients achieving complete remission after induction chemotherapy, two-thirds relapse within 5 years. AML follows a cellular hierarchy sustained by leukemia stem cells (LSCs), which drive tumor progression and relapse. Little is known about the genetic determinants driving LSCs stemness properties. By identifying chromatin variants from accessibility measurements across LSCs, hematopoietic stem cells and downstream progeny, we identified transposable...

CONCLUSIONS: Our procedure leads to successful (re)use of data in FL-based consortia without the need to impose a common schema at every point of origin of data.

Exposure to feelings of another can shape how we feel and think in that context. We propose that exposure to the feelings of multiple others carries broader implications that extend beyond the exposure context. We argue that people identify patterns of affective reactions in the social group, which leads them to infer affect norms. These norms, in turn, serve as benchmarks for subsequent social judgments. In four studies (N = 418), three of which were preregistered, we exposed participants to...

Inflammatory injury to the intestine triggers a reprogramming of the intestinal epithelium to a fetal-like state that drives rapid restoration of the epithelial barrier. Although the intestinal microbiota is a key modulator of inflammation, its role in influencing epithelial fetal-like stem cell reprogramming and consequent restitution remains unclear. Using irradiation (IR) injury as a model for small intestinal epithelium injury and repair, we found that the intestinal microbiota accelerated...

Mutations in the X-linked MECP2 gene cause the progressive neurodevelopmental disorder Rett syndrome. Pathogenic missense mutation hotspots exist in the protein's Methyl DNA binding Domain (MBD), and the Nuclear receptor Co-Repressor (NCoR) Interaction Domain (NID), indicating these regions as critical for MeCP2 function. The NID binds to a co-repressor complex allowing transcriptional repression at target genes. A putative RNA Binding Domain (RBD) was identified that overlaps with the NID, yet...

Deciphering how genes interact within human cells is essential for understanding their functional wiring and for developing targeted therapeutic strategies. In this study, we present a genome-scale map of genetic interactions in the human haploid cell line HAP1, based on CRISPR-based perturbation of ∼4 million gene pairs. The resulting network comprises ∼89,000 high-confidence gene-gene interactions, organizing genes into hierarchical modules corresponding to protein complexes and pathways,...

CONCLUSIONS: Our findings show that aggregate wearable data often fail to generalize across populations, oversimplifying pregnancy-related physiological and subjective changes. This simplification can obscure individual trajectories, leading to generalized insights that may not reflect many pregnant women's experiences. Our results highlight the impact of heterogeneity on pregnancy outcomes, emphasizing the need to move beyond one-size-fits-all models and leverage DHT for personalized care.

Genotoxic cancer therapies introduce DNA damage that can be fixed as somatic mutations in surviving tumor cells. However, the impact of therapy-associated mutagenesis on regulatory elements remains unclear. CTCF binding sites (CBS) are chromatin architectural elements that exhibit recurrent localized mutation enrichment in cancer genomes. We asked whether treatment exposure is associated with increased mutagenesis at CBS in 4,870 whole-genome sequences from metastatic tumors across 17 cancer...

CONCLUSION: These findings confirm the high prevalence of constipation-predominant intestinal dysfunction in patients with MWS. Collectively, our findings support further investigation of associations among feeding difficulties, a lower proportion of meat in dietary composition, and an altered fasting plasma neurotransmitter profile (including lower serotonin in a small subset), which may be relevant to gut dysmotility in patients with MWS. This diet-neurotransmitter axis offers a working model...

Objectives: To determine the incidence and outcomes of SARS-CoV-2 infection and to evaluate seroconversion rates and quantify antibody responses to COVID-19 vaccines in two cohorts of persons living with HIV at a possible higher risk of poor outcomes (HCV coinfection and those over the age of 65 years). Methods: We included participants from two established cohorts of persons living with HIV, those who were older than 65 years of age, and those with hepatitis C (HCV) co-infection. Four hundred...

Objectives: Allogeneic stem cell transplantation (HSCT) is curative in acute myeloid leukemia (AML) but is limited by relapse and non-relapse mortality (NRM). Metabolomic prognostic value is unclear. We assessed whether plasma metabolite profiles at diagnosis, pre-transplant, and post-transplant are associated with overall survival (OS) and cause-specific mortality. Methods: We retrospectively analyzed plasma metabolites from 63 AML patients undergoing HSCT (263 samples). Results: Higher levels...

In 2016, the Japan Children's Cancer Group launched a nationwide research initiative to provide central diagnosis incorporating pathology review and molecular profiling for pediatric central nervous system (CNS) tumors. Over the first eight years, 2224 cases were registered. Non-next-generation sequencing analyzes, such as pyrosequencing and NanoString, were routinely performed, mainly for glioma, medulloblastoma, and ependymoma. Additional analyzes, including methylation profiling and RNA...

BackgroundResearch indicates a significant overlap between transgender and gender-diverse (TGD) and autistic identities. This intersectional population has higher risks of mental health challenges and worse mental health outcomes than individuals with just one of the two identities. Limited research focuses on adults at this intersection and their care access needs. To better characterize this population in the Canadian context, this study examines the population referred to Canada's largest...
