The use of multispectral imaging to distinguish reactive urothelium from neoplastic urothelium

Journal of Pathology Informatics, 2010
The interpretation of urothelial atypia in a setting of chronic inflammation and reactive changes can prove difficult with small biopsies. Limited recuts lessen the efficacy of ancillary studies such as CK20, P53 and CD44 in these instances.To evaluate a triple-immunostain with the assistance of multispectral microscopy.Fifty-three bladder biopsies ...

Patient‐derived organoid‐immune co‐cultures integrated with multi‐omics reveal immunotherapy resistance mechanisms in urothelial carcinoma

iMeta, EarlyView.
Immunotherapy resistance presents a formidable challenge in tumor biology. While fibroblast growth factor receptor 3 (FGFR3) serves as a pivotal oncogenic driver in a multitude of cancers, the exploration of its role in immune checkpoint inhibitor (ICI) resistance remains scarce, thus impeding a deeper understanding of the tumor immune microenvironment

Beyond Tradition: An Integrated Toxicological, Ecological, and Public Health Perspective on Aristolochic Acids

Journal of Applied Toxicology, EarlyView.
ABSTRACT Aristolochia species have long been used in traditional medicine for their presumed anti‐inflammatory, analgesic and antimicrobial properties. However, extensive toxicological and epidemiological evidence now demonstrates that these plants contain aristolochic acids (AAs) I and II, highly potent nephrotoxic, genotoxic, and carcinogenic ...

POMC expression of the urothelium of the urinary bladder of mice submitted to pelvic radiation

European Journal of Inflammation, 2016
Objective: Patients who have had pelvic radiotherapy as part of their cancer therapy may develop subsequent urinary bladder injury. The acute changes that the urothelium undergo after radiation are known, but the healing mechanism of the urothelium of ...

How Can We Personalize the Delivery of Onabotulinumtoxin‐A for Patients With Neurogenic Lower Urinary Tract Dysfunction?

Neurourology and Urodynamics, EarlyView.
ABSTRACT Background & Aims Neurogenic lower urinary tract dysfunction (NLUTD) can produce bothersome urinary symptoms, impact quality of life, and in some cases, lead to deterioration of upper urinary tract function. Intradetrusor injection of onabotulinumtoxin‐A (BoNT‐A) is approved for NLUTD in patients who have an inadequate response to or ...

Peptide‐based responsive molecular fluorescent probes for precision oncology

Responsive Materials, EarlyView.
Peptide‐based responsive fluorescent probes have emerged as adaptive functional materials for precision tumor theranostics, combining tumor‐selective recognition, programmable stimulus responsiveness, and modular tunability. They enable high‐contrast imaging, intraoperative guidance, real‐time monitoring, and multimodal applications, while next ...

Androgen Receptor Expression in Urothelial Bladder Cancer—A Systematic Review and Meta‐Analysis

ANZ Journal of Surgery, EarlyView.
ABSTRACT Background Bladder cancer is a globally prevalent malignancy with a marked male predominance. Over the past decade, the androgen receptor has been investigated as a potential contributor to bladder cancer pathophysiology. Androgen receptor expression is most commonly assessed via immunohistochemistry, but its association with pathological ...

Directed differentiation of human induced pluripotent stem cells into mature stratified bladder urothelium

Scientific Reports, 2019
For augmentation or reconstruction of urinary bladder after cystectomy, bladder urothelium derived from human induced pluripotent stem cells (hiPSCs) has recently received focus. However, previous studies have only shown the emergence of cells expressing

A case of canine urothelial carcinoma of the urinary bladder with skull and skeletal metastases

Australian Veterinary Journal, EarlyView.
Canine urinary bladder neoplasia is uncommon, representing less than 1% of canine neoplasms. Amongst cases of urinary bladder neoplasia in dogs, primary urothelial carcinoma is the most frequent. Urothelial carcinomas are malignant invasive tumours which tend to be slow growing and metastasise late.
