At 76 patients an atypical epithelium of the uterine cervix was verified colposcopically, cytologically and by biopsy. The mean content and the distribution of DNA was measured by single cell-photometry of Feulgen-stained smears. These findings were compared with the spontaneous follow up of these cases. No correlation could be registered between DNA-characteristics and the fate of atypical epithelium, which was suitable for a clinical therapeutic resolution.

Hormonal Regulation of Urokinase- and Tissue-Type Plasminogen Activator in Mouse Sertoli Cells.

A role for the plasminogen activator (PA) system has been postulated in mammalian gonads, considering the complex process of morphogenesis these organs undergo during their development. Our results show that mouse Sertoli cells under basal conditions produce both types of PA, tissue-type PA (tPA) and urokinase-type PA (uPA), and hormonal treatments increase the production of both enzymes. The increased enzyme secretion does not correlate with a parallel increase in their mRNAs.

Objective: Urinary cytology is a key diagnostic tool for evaluating suspected urinary tract carcinoma, primarily high-grade urothelial carcinoma. The Paris System for Reporting Urinary Cytology (TPS), introduced in 2016, aimed to standardize reporting, though challenges with subjectivity and variability in diagnosing Atypical Urothelial Cells (AUCs) persist.
Methods: This retrospective study explored the correlation between cytomorphological features in "atypical" diagnosis and UroVysion fluorescence hybridization (U-FISH) results.

A 78-year-old male patient came to our hospital with a chief complaint of fever. Computed tomography revealed an indistinct tumor in the pancreatic head, along with dilatation of the bile duct and main pancreatic duct. An endoscopic transpapillary biopsy demonstrated adenocarcinoma in the glandular epithelium and a dense formation of quasi-round cells.

This report describes a patient with polypoidal choroidal vasculopathy (PCV) with fovea-involving retinal pigment epithelium (RPE) tear that showed tissue remodeling with a good visual outcome. Imaging over the patient's clinical course from 2019 was reviewed. A 74-year-old female presented with left submacular hemorrhage and a large multi-lobular pigment epithelial detachment.
