Validation of Aortic Blood Flow Simulations During Extracorporeal Circulation Using Phase Contrast Magnetic Resonance Imaging

open access: yesArtificial Organs, EarlyView.
This is the first study assessing in vivo blood flow profiles during extracorporeal circulation (ECC) scenarios. Magnetic resonance imaging data served for the calibration of computational fluid dynamics algorithms, enabling accurate replication of the hemodynamic conditions.

Carbohydrate metabolism of Xylella fastidiosa: Detection of glycolytic and pentose phosphate pathway enzymes and cloning and expression of the enolase gene

open access: yesGenetics and Molecular Biology, 2003
The objective of this work was to assess the functionality of the glycolytic pathways in the bacterium Xylella fastidiosa. To this effect, the enzymes phosphoglucose isomerase, aldolase, glyceraldehyde-3-phosphate dehydrogenase and pyruvate kinase of the

From patient to tumor organoid: Culture protocol choice controls glioblastoma tumor architecture and identity

open access: yesBrain Pathology, EarlyView.
How glioblastoma organoids are made shapes what they become. Fragment‐based cultures preserve extracellular matrix networks, cellular diversity, and primary tumor identity, whereas dissociation‐based cultures shift toward growth‐adapted states and simplified microenvironments. Abstract Patient‐derived tumor organoids are widely used in cancer research,

Urinary Small Extracellular Vesicle DNA as a Biomarker for the Non‐Invasive Diagnosis of Bladder Cancer

open access: yesCancer Science, EarlyView.
Clinical application scenarios for the diagnosis of BC. A schematic diagram illustrating the use of sEV DNA liquid biopsy technology to differentiate between benign and bladder cancer patients. ABSTRACT Existing diagnostic technologies for bladder cancer (BC) suffer from low sensitivity, low specificity, or a lack of validation.

Common pathways and outliers in glucose catabolism across Trypanosomatidae

open access: yesThe FEBS Journal, EarlyView.
Trypanosomatid parasites, including Trypanosoma sp., Leishmania sp., Phytomonas sp., and Vickermania sp., share a common motif: a metabolism built around the glycosome, a unique peroxisome‐derived organelle housing the first steps of glycolysis. Yet, these organisms have evolved remarkably diverse strategies to catabolize glucose, excreting distinct ...

Merkel cell carcinoma: an updated guide for pathologists

open access: yesHistopathology, EarlyView.
Merkel cell carcinoma (MCC) is an aggressive cutaneous neuroendocrine carcinoma for which the differential diagnosis can include other small cell malignancies (especially metastatic small cell carcinoma) or cutaneous carcinoma. Morphologic and immunophenotypic aberrancies in MCC can increase diagnostic challenge.

Life‐stage variation in Sable Shearwater (Ardenna carneipes) physiology assessed using proteomics

open access: yesIbis, EarlyView.
Life‐stage transitions in seabirds involve substantial shifts in physiological demands, yet the molecular mechanisms underpinning these changes remain poorly resolved. Here we applied untargeted data‐independent acquisition mass spectrometry (DIA‐MS) to characterize and compare the plasma proteomes of fledgling and adult Sable Shearwaters Ardenna ...

Autoimmunity and Periodontitis

open access: yesJournal of Periodontal Research, EarlyView.
In a microbe‐driven inflammatory environment, peptidyl‐arginine deiminase (PAD) enzymes from neutrophils and Porphyromonas gingivalis citrullinate both microbial and self‐antigens. B cell presentation of citrullinated or self‐mimicking epitopes activates T cells that assist B cells in antibody isotype switching, affinity maturation, epitope spreading ...

Periodontal Medicine Rewired: Mechanisms Linking Periodontitis to Systemic Diseases

open access: yesJournal of Periodontal Research, EarlyView.
This review reorganizes decades of research in periodontal medicine into a multi‐dimensional framework, illustrating how periodontitis influences systemic health through at least seven interconnected mechanisms. ABSTRACT Periodontitis is now recognized not merely as a localized oral condition but as a systemic disease linked to over 70 communicable and

Periodontitis and Rheumatoid Arthritis—Mechanistic Evidence

open access: yesJournal of Periodontal Research, EarlyView.
Periodontitis and rheumatoid arthritis are linked via the two‐hit model whereby early periodontal inflammation can lead to autoantibody production capable of interacting with inflamed synovial tissues. Subsequent systemic inflammation can exacerbate the periodontal inflammatory response and bacterial dysbiosis leading to further autoantibody production
