Accurate prognosis prediction is essential for guiding cancer treatment and improving patient outcomes. While recent studies have demonstrated the potential of histopathological images in survival analysis, existing models are typically developed in a cancer-specific manner, lack extensive external validation, and often rely on molecular data that are not routinely available in clinical practice. To address these limitations, we present PROGPATH, a unified model capable of integrating...

Introduction. Infection is a leading cause of mortality during the first year of life, with the neonatal period being particularly high risk. It is critical to identify non-antibiotic approaches to improve neonatal infection outcomes due to the non-specific clinical signs of neonatal infection and negative consequences of early-life antibiotic exposure. Lactoferrin is a protein found in all mammalian milk that has a variety of antimicrobial properties. Clinical trials have shown that lactoferrin...

Influenza A virus (IAV) is a zoonotic pathogen responsible for seasonal and pandemic flu. The extensive genetic and antigenic diversity within and between IAV phylogenetic groups presents major challenges for developing universal vaccines and broad-spectrum antiviral therapies. Current interventions provide limited protection due to the virus's high mutation rate and capacity for immune evasion. Recent advancements in viral hemagglutinin (HA)-targeting small-molecule entry inhibitors offer a...

PURPOSE OF REVIEW: This review article examines the evolving evidence on cancer recurrence and new malignancy risk associated with disease-modifying antirheumatic drugs (DMARDs), including TNF inhibitors, rituximab, IL-6 inhibitors, and JAK inhibitors, in patients with rheumatoid arthritis and a prior malignancy.

Human challenge models (CHIMs) are instrumental in advancing influenza research but have traditionally relied on intranasal inoculation, which does not mimic the natural aerosol transmission of the virus. We conducted a dose-escalation influenza CHIM study to evaluate the safety and feasibility of two modern aerosol delivery systems: a flow-focusing monodisperse aerosol generator (FMAG) and a medical nebulizer. Fourteen healthy adults aged 18-49 years were exposed to influenza A/Perth/16/2009...

The H5N1 strain of influenza A virus (IAV) continues to cause severe infections in a range of avian and mammalian species, including sporadic but concerning cases in humans. There is growing concern that circulating H5N1 strains could lead to widespread human outbreaks. Research with highly pathogenic H5N1 viruses is restricted to Biosafety Level 3 (BSL-3) laboratories. Vesicular stomatitis virus (VSV)-based vaccine vectors expressing heterologous viral proteins from Ebola, SARS-CoV-2, Lassa...

CONCLUSION: Palmitate-exposed MSCs show enhanced immunomodulation of human MDMs, through the ceramide/CCL2 axis in vitro.

TNF receptor-associated factor 3 (TRAF3) is a signaling adaptor protein that is ubiquitously expressed but has highly distinct cell type-specific functions. TRAF3 plays critical roles in restraint of B lymphocyte activation, differentiation, and homeostatic survival. Consistent with such roles, loss-of-function mutations in TRAF3 have long been found in various human B cell malignancies. Mice lacking TRAF3 specifically in B cells have autoimmune manifestations, lymphadenopathy, and increased...

Cystic fibrosis transmembrane conductance regulator (CFTR) modulators improve the physiological defect causing cystic fibrosis, but the lungs of most people remain infected and inflamed. A leading hypothesis implicates damaged segments as the cause of persistent infection and predicts that mildly diseased segments within an individual's lungs will clear after treatment, whereas severely diseased segments will not. Our findings contradict this hypothesis. We used bronchoscopy to sample the least-...

Parkinson's disease (PD) is a progressive neurodegenerative disorder marked by substantial degeneration of dopaminergic neurons in the substantia nigra and dopamine depletion in the striatum, leading to debilitating motor and non-motor impairments. Recent studies provide clues on the pathogenic role of DNA damage in age-related neurodegenerative diseases, but the molecular mechanisms of DNA damage response in PD remain poorly understood. We found that the accumulation of DNA double-strand breaks...
