Lateral Atrial Expression Patterns Provide Insights into Local Transcription Disequilibrium Contributing to Disease Susceptibility.

Background: Transcriptional dysregulation, possibly affected by genetic variation, contributes to disease development. Due to dissimilarities in development, function, and remodeling during disease progression, transcriptional differences between the left atrial (LA) and right atrial (RA) may provide insight into diseases such as atrial fibrillation.

Methods: Lateral differences in atrial transcription were evaluated in CATCH ME (Characterizing Atrial fibrillation by Translating its Causes into Health Modifiers in the Elderly) using a 2-stage discovery and replication design.

RNAi-based ALOX15B silencing augments keratinocyte inflammation in vitro via EGFR/STAT1/JAK1 signalling.

Arachidonate 15-lipoxygenase type B (ALOX15B) peroxidises polyunsaturated fatty acids to their corresponding fatty acid hydroperoxides, which are subsequently reduced into hydroxy-fatty acids. A dysregulated abundance of these biological lipid mediators has been reported in the skin and blood of psoriatic compared to healthy individuals. RNAscope and immunohistochemistry revealed increased ALOX15B expression in lesional psoriasis samples.

Prostate-specific Membrane Antigen-radioguided Surgery in an EMBARK-like Cohort of Patients with Oligorecurrent Hormone-sensitive Prostate Cancer: Delay in Systemic Treatment.

We analyzed data for a cohort of 111 patients with EMBARK-like biochemical recurrence (BCR) of prostate cancer (prostate-specific antigen [PSA] doubling time ≤9 mo, PSA ≥1 ng/ml) after radical prostatectomy and localized oligorecurrence on prostate-specific membrane antigen (PSMA)-based imaging. All patients underwent PSMA-radioguided surgery (RGS). At PSMA-RGS, the median PSA was 1.

The clinical and molecular landscape of diffuse hemispheric glioma, H3 G34-mutant.

Background: Diffuse hemispheric glioma, histone 3 (H3) G34-mutant, has been newly defined in the 2021 WHO classification of central nervous system tumors. Here we sought to define the prognostic roles of clinical, neuroimaging, pathological, and molecular features of these tumors.

Methods: We retrospectively assembled a cohort of 114 patients (median age 22 years) with diffuse hemispheric glioma, H3 G34-mutant, CNS WHO grade 4 and profiled the imaging, histological and molecular landscape of their tumors.

Perioperative Chemotherapy or Preoperative Chemoradiotherapy in Esophageal Cancer.

Background: The best multimodal approach for resectable locally advanced esophageal adenocarcinoma is unclear. An important question is whether perioperative chemotherapy is preferable to preoperative chemoradiotherapy.

Methods: In this phase 3, multicenter, randomized trial, we assigned in a 1:1 ratio patients with resectable esophageal adenocarcinoma to receive perioperative chemotherapy with FLOT (fluorouracil, leucovorin, oxaliplatin, and docetaxel) plus surgery or preoperative chemoradiotherapy (radiotherapy at a dose of 41.

Involvement of RBP-J interacting and tubulin-associated protein in the distribution of protein regulator of cytokinesis 1 in mitotic spindles.

The protein regulator of cytokinesis 1 (PRC1) is a key regulator of microtubule crosslinking and bundling, which is crucial for spindle formation and cytokinesis. RITA, the BP-J nteracting and ubulin-ssociated protein, is a microtubule associated protein. We have reported that RITA localizes to mitotic spindles modulating microtubule dynamics and stability as well as to spindle poles affecting the activity of Aurora A.

Olfactory Dysfunction in Children and Adolescents-A Diagnostic Pathway.

Olfactory disorders have so far played a subordinate role in pediatric care, although children can also be affected. Due to a lack of awareness, the diagnosis can often only be made after numerous visits to the doctor, although it can significantly impact the quality of life. Olfactory disorders in adults are usually acquired, while congenital causes dominate in children.

SILAC-based quantification reveals modulation of the immunopeptidome in BRAF and MEK inhibitor sensitive and resistant melanoma cells.

Background: The immunopeptidome is constantly monitored by T cells to detect foreign or aberrant HLA peptides. It is highly dynamic and reflects the current cellular state, enabling the immune system to recognize abnormal cellular conditions, such as those present in cancer cells. To precisely determine how changes in cellular processes, such as those induced by drug treatment, affect the immunopeptidome, quantitative immunopeptidomics approaches are essential.

BRAT1 - a new therapeutic target for glioblastoma.

Glioblastoma (GBM), the most malignant primary brain tumor in adults, has poor prognosis irrespective of therapeutic advances due to its radio-resistance and infiltrative growth into brain tissue. The present study assessed functions and putative druggability of BRCA1-associated ATM activator 1 (BRAT1) as a crucial factor driving key aspects of GBM, including enhanced DNA damage response and tumor migration. By a stable depletion of BRAT1 in GBM and glioma stem-like (GSC) cell lines, we observed a delay in DNA double-strand break repair and increased sensitivity to radiation treatment, corroborated by in vitro and in vivo studies demonstrating impaired tumor growth and invasion.

In-Hospital Outcomes after Robotic Open Radical Nephroureterectomy.

To test whether the contemporary robot-assisted nephroureterectomy (RNU) is associated with more favorable in-hospital outcomes than historical RNU, relative to the same endpoints in open NU (ONU). Within the National Inpatient Sample (2008-2019), we identified RNU and ONU patients. Multivariable logistic and Poisson regression models were fitted.

Cancer-specific mortality after radical prostatectomy versus radiotherapy in incidental prostate cancer.

Introduction: To test for cancer specific mortality (CSM) differences after either radical prostatectomy (RP) or radiotherapy (RT) in incidental prostate cancer (IPCa) patients.

Patients And Methods: Within the Surveillance, Epidemiology, and End Results (SEER) database (2004-2015), IPCa patients were identified. Cumulative incidence plots as well as competing risks regression (CRR) models were fitted to address CSM after adjustment for other-cause mortality (OCM).

New onset refractory status epilepticus: Long-term outcomes beyond seizures.

We propose and prioritize important outcome domains that should be considered for future research investigating long-term outcomes (LTO) after new onset refractory status epilepticus (NORSE). The study was led by the international NORSE Institute LTO Working Group. First, literature describing the LTO of NORSE survivors was identified using a PubMed search and summarized to identify knowledge gaps.

Multinational retrospective analysis of bridging therapy prior to chimeric antigen receptor t cells for relapsed/refractory acute lymphoblastic leukemia in children and young adults.

Anti-CD19 chimeric antigen receptor T cells (CAR) are a well-established treatment option for children and young adults suffering from relapsed/refractory B-lineage acute lymphoblastic leukemia. Bridging therapy is used to control disease prior to start of lymphodepletion before CAR infusion and thereby improve efficacy of CAR therapy. However, the effect of different bridging strategies on outcome, side effects and response to CAR therapy is still poorly understood.

B-doped nano-hydroxyapatite facilitates proliferation and differentiation of osteoblasts.

Purpose: We aimed to explore the mechanism by which Boron-doped nano-hydroxyapatite (B-nHAp) facilitates the proliferation and differentiation of osteoblasts through controlled release of B.

Methods: B-nHAp characterization was accomplished by means of X-ray diffraction, scanning electron microscopy, inductively coupled plasma mass spectrometry, and transmission electron microscopy. Human bone marrow mesenchymal stem cells (hBMSCs) were subjected to flow cytometry, alizarin red S staining, and cell counting kit-8 assay for proliferation and differentiation determination.

Accurate melanoma diagnosis is crucial for patient outcomes and reliability of AI diagnostic tools. We assess interrater variability among eight expert pathologists reviewing histopathological images and clinical metadata of 792 melanoma-suspicious lesions prospectively collected at eight German hospitals. Moreover, we provide access to the largest panel-validated dataset featuring dermoscopic and histopathological images with metadata.

Repeat Procedures After Pulsed Field Ablation for Atrial Fibrillation: MANIFEST-REDO Study.

Background: Initial clinical studies of pulsed field ablation (PFA) to treat atrial fibrillation (AF) indicated a >90% durability rate of pulmonary vein isolation (PVI). However, these studies were largely conducted in single centers and involved a limited number of operators. The electrophysiological findings and outcomes in patients undergoing repeat ablation after an initial PF ablation for AF are incompletely understood.

Protocol for the Generation and 3D Culture of Fluorescently Labeled Multicellular Spheroids.

Spheroid culture systems have been extensively used to model the three-dimensional (3D) behavior of cells in vitro. Traditionally, spheroids consist of a single cell type, limiting their ability to fully recapitulate the complex inter-cellular interactions observed in vivo. Here we describe a protocol for generating cocultured spheroids composed of two distinct cell types, embedded within a 3D extracellular matrix (ECM) to better study cellular interactions.

Mitochondria-Targeted Antioxidant (MitoQ) and Nontargeted Antioxidant (Idebenone) Mitigate Mitochondrial Dysfunction in Corneal Endothelial Cells.

Purpose: To investigate the effectiveness of mitochondrial-targeted antioxidant mitoquinone (MitoQ) and nontargeted antioxidant idebenone (Idb) in alleviating mitochondrial dysfunction in corneal endothelial cells (CEnCs).

Methods: In vitro experiments were conducted using immortalized normal human corneal endothelial cells (HCEnC-21T; SVN1-67F) and Fuchs endothelial corneal dystrophy (FECD) cells (SVF5-54F; SVF3-76M). Cells were pretreated with MitoQ or Idb and then exposed to menadione (MN) with simultaneous antioxidant treatment.

Borderline Findings in -(2-[F]-Fluoroethyl)-l-Tyrosine PET of Patients with Suspected Glioma Relapse: Role in Clinical Practice.

One of the most common clinical indications for amino acid PET using the tracer -(2-[F]-fluoroethyl)-l-tyrosine (F-FET) is the differentiation of tumor relapse from treatment-related changes in patients with gliomas. A subset of patients may present with an uptake of F-FET close to recommended threshold values. The goal of this study was to investigate the frequency of borderline cases and the role of quantitative F-FET PET parameters in this situation.

Immunohistochemistry-based molecular subtypes of urothelial carcinoma derive different survival benefit from platinum chemotherapy.

Distinct molecular subtypes of muscle-invasive bladder cancer (MIBC) may show different platinum sensitivities. Currently available data were mostly generated at transcriptome level and have limited comparability to each other. We aimed to determine the platinum sensitivity of molecular subtypes by using the protein expression-based Lund Taxonomy.
