Utilizing immunocytochemistry to determine the etiology of metastatic carcinomatous brain lesions: a detailed case series

open access: yesMGM Journal of Medical Sciences
Background: Metastatic involvement of the brain is a common and serious event in the progression of various cancers. Determining the primary source of brain metastases (BM) presents a significant diagnostic challenge, especially when histopathological ...

Cytology‐First Diagnostic Workflow for Melanoma of Unknown Primary With Molecular Profiling

open access: yesCytopathology, EarlyView.
Cytology‑first diagnostic workflow for melanoma of unknown primary. Fine‑needle aspiration of an enlarged lymph node enables rapid cytologic evaluation and immunocytochemical confirmation of melanocytic lineage (SOX10). This early cytologic diagnosis facilitates timely surgical excision and comprehensive genomic profiling, supporting integrated ...

Evaluating Fine Needle Aspiration Cytology for Diagnostics of Soft Tissue and Bone Tumours

open access: yesCytopathology, EarlyView.
Systematic comparison of needle aspiration cytology and histopathology for 503 tumours in soft tissue and bone showed high concordance (positive predictive value 94%–100%, negative predictive value 83%–89%). In this original study, the authors show that FNAC is a safe and non‐invasive method for diagnosing suspected sarcomas, with the main objective to

Repositioning Non‐Ablative Fractional Lasers ‐ Molecular and Histological Insights from a scoping review

open access: yesJDDG: Journal der Deutschen Dermatologischen Gesellschaft, EarlyView.
Summary Near‐infrared non‐ablative fractional lasers (NAFL) are established for skin rejuvenation and scar treatment and have attracted interest for their expanding therapeutic potential. This scoping review aims to revisit and reposition NAFL within a fluence‐dependent continuum of tissue modulation, based on evidence from 27 studies of lasers ...

A DPP6‐Targeted PET Tracer for Non‐Invasive Imaging of Transplanted Human Islets

open access: yesDiabetes, Obesity and Metabolism, EarlyView.
ABSTRACT Introduction Dipeptidyl peptidase‐like protein 6 (DPP6) is a potential molecular imaging biomarker for pancreatic and transplanted islets of Langerhans. 4hD29 is a single‐domain antibody with nanomolar affinity for DPP6. Here, we demonstrate the generation and validation of [68Ga]Ga‐NOTA‐4hD29 for Positron Emission Tomography (PET) imaging of ...

Alterations of bone proteins in medication‐related osteonecrosis of the jaw

open access: yesEuropean Journal of Oral Sciences, Volume 133, Issue 2, April 2025.
Abstract Changes in the protein expression pattern of osteoblastic lineage cells from the alveolar bone (OLAB) during medication‐related osteonecrosis of the jaw (MRONJ) have rarely been investigated. This lack of information is partly because of the limited availability of healthy samples and the lack of human alveolar bone cell lines for research ...

Persistent in vitro nociceptor hyperexcitability and axonal retraction produced by repeated paclitaxel doses

open access: yesThe FEBS Journal, EarlyView.
Repeated paclitaxel exposure causes long‐lasting nociceptor hyperexcitability and axonal retraction in adult sensory neurons. Using a long‐term primary nociceptor culture, we show that hyperexcitability is mediated by sequential upregulation of NaV1.8, TRPV1, TRPA1, and TRPM8 channels.

TOP1MT rs2293925 is an enhancer‐active regulatory SNP that shapes mitochondrial R‐loop dynamics

open access: yesThe FEBS Journal, EarlyView.
This study shows how a common genetic variant of mitochondrial topoisomerase 1 (TOP1MT rs2293925) can influence mitochondrial gene regulation, DNA topology, and formation of noncanonical nucleic acid structures such as R‐loops. By linking this enhancer‐active variant to mitochondrial nucleic acid stress in cellular contexts relevant to amyotrophic ...

UK recommendations for Ki‐67 immunohistochemical staining and interpretation in breast cancer

open access: yesHistopathology, EarlyView.
Where possible, a validated digital imaging system should be utilized. If this is not available, then intermediate scores (5%–30%) should be thoroughly assessed using the Ki‐67 International Working Group guidance. Difficult cases should be double scored.

Synergistic Effects of Bacterial Mimetic and Mechanical Stimulation in Dental Pulp Cell Inflammatory Signalling: A Laboratory Investigation

open access: yesInternational Endodontic Journal, EarlyView.
ABSTRACT Objectives Mechanical and/or microbial stimuli can prompt extracellular ATP release in many cell types, where it acts as an inflammatory mediator to amplify pain signals and inflammation. This study aimed to investigate the synergistic effects of microbial and/or mechanical stimulation on ATP and cytokine release from dental pulp cells (DPCs ...
