Integrated metabolomics data analysis to generate mechanistic hypotheses with MetaProViz

ABSTRACT With the growing number of metabolomics and lipidomics studies, robust strategies for bioinformatic analyses are increasingly important. However, the absence of standardized and reproducible workflows, coupled with ambiguous metabolite annotations, hampers effective anal...

Molecular characterization of mismatch repair deficient tumors in young Jordanian patients

<title>Abstract</title> In Jordan, approximately 19% of colorectal carcinomas (CRCs) in patients younger than 45 years show mismatch repair deficiency (MMRD) by immunohistochemistry (IHC). MMRD in pediatric high-grade gliomas (HGG) and CRC in Jordan appears substantially more fre...

Longitudinal Tumor, Vascular, and Immune Cell Response in Two Rat Prostate Carcinomas After Isoeffective Photon, Proton, and Carbon Ion Irradiation: Impact of Linear Energy Transfer, Dose Level, and Hypoxia

Background/Objectives: High linear energy transfer (LET) carbon ions achieved more effective and biologically robust tumor control than photons in preclinical prostate cancer models; however, the longitudinal development of histopathological parameters remains insufficiently char...

Prospective analysis of pre-diagnostic untargeted plasma metabolomics and risk of triple-negative breast cancer in the European Prospective Investigation into Cancer and Nutrition (EPIC)

Triple-negative breast cancer (TNBC) accounts for 10–15% of newly diagnosed breast cancer, and its aetiology is poorly understood compared to other breast cancer subtypes. We applied untargeted metabolomics to identify novel biological pathways associated with TNBC risk and poten...

Technical note: reconstructing dose distributions from manually planned electron boosts in breast radiotherapy

Purpose In breast radiotherapy, delivery of manually-calculated electron boosts limits retrospective dose–response analyses as dose distribution is unavailable. This work evaluates the feasibility of reconstructing dose distributions from manually planned electron boosts in breas...

External validation of a top-ranked model from the RSNA pulmonary embolism detection challenge: assessment of generalizability

Abstract To externally validate the RSNA 2020 challenge 2 nd -place deep-learning (DL) algorithm for detecting pulmonary embolism (PE) on computed tomography pulmonary angiography (CTPA) scans with additional focus on subsegmental-only PEs (SSPE). Between 2015 and 2022 1,038 CTPA...

Durable clinical and immunologic response to an off-the-shelf EWSR1–FLI1 peptide vaccine in metastatic Ewing sarcoma

Abstract Ewing sarcoma is a rare, fusion-driven malignancy with poor prognosis in the metastatic setting, for which no established immunotherapeutic treatment is currently available. Fusion breakpoints are rational precision immunotherapy targets, yet clinical evidence of immunog...

Accelerating Translation of NK Cell Therapies to the Clinic: A European Perspective

Adoptive immunotherapies have emerged as a promising strategy in the treatment of hematological malignancies. To date, seven chimeric antigen receptor (CAR)-T cell products have obtained market authorization in Europe for B-cell malignancies, where they have revolutionized treatm...

HLA-dependent association between EBNA1 antibody levels and disability progression in multiple sclerosis

Background Epstein-Barr virus (EBV) is strongly implicated in the development of multiple sclerosis (MS) but whether EBV-related immune responses are also relevant for disease progression after diagnosis remains unclear. We investigated whether Epstein-Barr nuclear antigen 1 (EBN...
