Herein, 26 rhodamine fluorophores were synthesized from readily available Rh-6G and relative amines at room temperature with good selectivity, functional groups compatibility and high yields. We found that one of them 3f showed pH-dependent anticancer bioactivity, with cell viability of 68.4% under pH 6.5 and 83.2% under pH 7.5, LDH fold change of 42.8% under pH 6.5 and 26.4% under pH 7.5 in 22.35 μM in human bladder cancer cell line EJ. Besides, 3f showed anticancer bioactivity in vivo towards human bladder cancer, by triggering apoptosis through mitochondrial pathway.

Clinicopathological features and treatment outcomes of urothelial carcinoma variant histologies and non-urothelial bladder cancers.

Purpose: Most bladder cancers are pure urothelial carcinomas, but a small portion, approximately 5-10%, have variant histology or are non-urothelial in nature. This research sought to examine the features of and treatment strategies for different types of urothelial carcinoma with variant histologies and non-urothelial bladder cancer.
Methods: The study cohort comprised individuals with non-urothelial and variant urothelial bladder cancers treated at two medical centres in Ankara, Turkey, between 2005 and 2024.
Efficient radiolabeling of mesoporous silica nanoparticles for single-cell PET imaging.

Purpose: Nanoparticles are highly efficient vectors for ferrying contrast agents across cell membranes, enabling ultra-sensitive in vivo tracking of single cells with positron emission tomography (PET). However, this approach must be fully characterized and understood before it can be reliably implemented for routine applications.
Methods: We developed a Langmuir adsorption model that accurately describes the process of labeling mesoporous silica nanoparticles (MSNP) with Ga.
Impact of Endocrine Disruptors on the Genitourinary Tract.

Over the last decades, the human species has seen an increase in the incidence of pathologies linked to the genitourinary tract. Observations in animals have allowed us to link these increases, at least in part, to changes in the environment and, in particular, to an increasing presence of endocrine disruptors. These can be physical agents, such as light or heat; natural products, such as phytoestrogens; or chemicals produced by humans.

Circulating tumor cells and cell-free nucleic acids are novel diagnostic, prognostic and predictive tools for non-invasive and cost-effective cancer detection in liquid biopsy. Carbonic anhydrase IX (CAIX) has been proposed as a biomarker in urogenital tumors and urine sediment. Our aim was to evaluate CAIX full-length percentage (CAIX FL%) in urine-cell-free RNA (cfRNA) and its relationship with tumor-cell-associated RNA (TC-RNA).

Our aim was to describe the incidence and mortality of genitourinary (GU) cancers in rural and urban Pennsylvania counties. We calculated age-adjusted incidence and mortality rates of GU (prostate, bladder, and kidney) cancers from 1990 to 2019 in the Pennsylvania Cancer Registry. We defined rurality using the Center for Rural Pennsylvania's population density-based definition.
