AI Article Synopsis
- The study aimed to quantitatively analyze the cellular characteristics of intraductal dysplasia (ID), distinguishing between two grades, and comparing them to benign prostatic hyperplasia (BPH) and adenocarcinoma (AC).
- Key findings included a consistent increase in mean nuclear area and nuclear-cytoplasmic (N/C) ratio from BPH to ID to AC, with mean cellular area showing varied values across the conditions.
- Additionally, ID demonstrated higher stratification features compared to BPH but lower in AC, indicating that certain nuclear features can help differentiate between BPH, ID grades, and AC effectively.
Article Abstract
The aim of our study was to characterize quantitatively the cellular and architectural features of intraductal dysplasia (ID) (subdivided into two grades), in comparison with benign prostatic hyperplasia (BPH) and adenocarcinoma (AC). The research was carried out on histological sections where the mean nuclear and cellular area, the mean nuclear cytoplasmic (N/C) ratio and parameters related to nuclear crowding and stratification were evaluated. The mean nuclear area and the mean N/C ratio steadily increased from BPH to ID and to AC. As for the mean cellular area, the values decreased from BPH to ID grade 1: in the two grades of ID the values remained about the same; in the AC, the mean cellular area was intermediate between ID and PBH. The mean crowding index showed increase in ID grade I, in comparison with BPH, and then a decline from ID grade 2 to AC. The stratification related features (mean epithelial height, mean nuclear stratification height, stratification index) showed ID values greater than in BPH, while in AC smaller than in BPH; in ID grades 1 and 2 the values were similar. The results clearly indicate that mean nuclear area helps to discriminate BPH and AC. A partial separation between the two grades of ID is possible by combining the mean nuclear area and the mean nuclear crowding index in a bivariate analysis.

Preventive interventions are expected to substantially improve the prognosis of patients with primary liver cancer, predominantly hepatocellular carcinoma (HCC) and cholangiocarcinoma. HCC prevention is challenging in the face of the evolving etiological landscape, particularly the sharp increase in obesity-associated metabolic disorders, including metabolic dysfunction-associated steatotic liver disease (MASLD). Next-generation anti-HCV and HBV drugs have substantially reduced, but not eliminated, the risk of HCC and have given way to new challenges in identifying at-risk patients.

l-Asparaginase (l-ASNase) catalyzes the hydrolysis of l-asparagine, leading to its depletion and subsequent effects on the cellular proliferation and survival. In contrast to normal cells, malignant cells that lack asparagine synthase are extremely susceptible to asparagine deficiency. l-ASNase has been successfully employed in treating pediatric leukemias and non-Hodgkin lymphomas; however, its usage in adult patients and other types of cancer is limited due to significant side effects and drug resistance.

A predictive model for long-term survival is needed, and mitochondrial dysfunction is a key feature of cancer metabolism, though its link to glioma is not well understood. The aim of this study was to identify the molecular characteristics associated with glioma prognosis and explore its potential function. We analyzed RNA-seq data from The Cancer Genome Atlas and identified differentially expressed mitochondrial long noncoding RNAs (lncRNAs) using R's 'limma' package.

Mitochondria represent pivotal cellular organelles endowed with multifaceted functionalities encompassing cellular respiration, metabolic processes, calcium turnover, and the regulation of apoptosis, primarily through the generation of reactive oxygen species (ROS). Perturbations in mitochondrial dynamics have been intricately linked to the etiology of numerous cardiovascular pathologies, such as heart failure, ischemic heart disease, and various cardiomyopathies. Notably, recent attention has been directed towards the detrimental impact of micro- and nanoplastic pollution on mitochondrial integrity, an area underscored by a paucity of comprehensive investigations.
