The present study aimed at analysing the intensity of apoptosis, as related to the expression of pro- and anti-apoptotic cellular markers (cas-3, MT, Ki-67 antigen), and at evaluating their expression in relation to the survival time of patients with colorectal adenocarcinoma. Material for the studies was obtained from 40 patients with primary colorectal adenocarcinomas (G2, T3N0M0), treated at the Lower Silesia Centre of Oncology in Wrocław. Tumour samples were fixed in 4% buffered formalin and embedded in paraffin blocks. In obtained paraffin sections, TUNEL reaction (detection of apoptosis) and immunocytochemical reactions were performed (detection of cas-3, MT and Ki-67 antigen expression). The results disclosed a weak correlation between the intensity of apoptosis and the expression of MT, cas-3 and Ki-67 antigen (r = 0.18; r = 0.33; r = 0.15, respectively) in cells of colorectal adenocarcinomas. The survival time of the patients was shorter, when the apoptosis and expression of Ki-67 antigen were highly pronounced. The time periods of the patients' survival showed no correlation with the expression of cas-3 or MT. The obtained results point to the key role of apoptosis and proliferation processes in the clinical course of colorectal adenocarcinomas.

CT-based machine learning radiomics predicts Ki-67 expression level and its relationship with overall survival in resectable pancreatic ductal adenocarcinoma.

Background: The prognostic prediction of pancreatic ductal adenocarcinoma (PDAC) remains challenging. This study aimed to develop a radiomics model to predict Ki-67 expression status in PDAC patients using radiomics features from dual-phase enhanced CT, and integrated clinical characteristics to create a radiomics-clinical nomogram for prognostic prediction.
Methods: In this retrospective study, data were collected from 124 PDAC patients treated surgically at a single center, from January 2017 to March 2023.
Resolution of oncogene-induced senescence markers in HPV-infected cervical cancer tissue.

Department of Pharmacology and Public Health, Faculty of Medicine, The Hashemite University, Zarqa, 13133, Jordan.
Background: Oncogene-Induced Senescence (OIS) is a form of senescence that occurs as a consequence of oncogenic overstimulation and possibly infection by oncogenic viruses. Whether senescence plays a role in the pathogenesis of cervical cancer (CC) is not well understood. Moreover, whether cervical epithelial cells that are part of the premalignant cervical intraepithelial neoplasia (CIN), exhibit markers of OIS in Human Papillomavirus (HPV)-infected tissue, has not been investigated.

Rationale: Follicular tumors with uncertain malignant potential of the thyroid are a new classification of thyroid tumors in the World Health Organization (2017). Only a few cases of evaluating the value of ultrasound combined with pathological examination in diagnosing follicular tumors with uncertain malignant potential of the thyroid have been reported in recent decades.
Patient Concerns: A retrospective analysis was performed on 18 patients with follicular tumors with uncertain thyroid malignant potential who underwent preoperative ultrasonography and were confirmed by operation and pathology in our hospital from January 2019 to November 2024.
Increased Phosphorylation of Intracellular Signaling Molecules Indicates Continuous Activation of Human Autoreactive B-Cells.

Many human autoimmune diseases (AIDs) are hallmarked by the presence and persistence of autoreactive B-cells. While autoreactive B-cells may frequently encounter antigens, the signals required to balance and maintain their activation and survival are mostly unknown. Understanding such signals may be important for strategies aimed at eliminating human B-cell autoreactivity.

Objectives: This study aimed to compare apparent diffusion coefficient (ADC) values derived from diffusion-weighted imaging (DWI) of different Borrmann types of advanced gastric cancer (AGC) and correlate these ADC values with Ki-67 expression and serum CEA levels in AGC.
Methods: A total of 84 patients with AGC who underwent DWI of the upper abdomen before tumor resection in our hospital between June 2014 and July 2018 were included in the present study. DWI was obtained with a single-shot echo planar imaging sequence in the axial plane (b values: 0, 100, 700 and 1000 s/mm).
