tumour specific surgery in colon cancer is gaining popularity among colorectal surgeons. Many advocate adapting surgical technique based on preoperative CT staging as not all patients require complete mesocolic excision (CME) and D3 lymphadenectomy. We aimed to assess the sensitivity and specificity of preoperative CT scans in nodal staging and analyse whether inadequate CT staging could have influenced local recurrences.

Hepatic mesenchymal hamartoma (HMH) is an uncommon, benign liver tumor predominantly affecting children under three years of age. It is characterized histologically by disorganized mesenchymal stroma, abnormal bile ducts, blood vessels, and hepatocytes. HMH can present as a large cystic mass, a solid mass, or a combination of both.

Background: We investigated the effects of C-reactive protein (CRP) deposition on the vessel walls in abdominal aortic aneurysm (AAA) by analyzing spatially resolved changes in gene expression. Our aim was to elucidate the pathways that contribute to disease progression.
Methods: AAA specimens from surgically resected formalin-fixed paraffin-embedded tissues were categorized into the AAA-high CRP [serum CRP ≥ 0.
The Impact of Physical Activity on Abdominal Aortic Aneurysm: A Scoping Review.

Background: Abdominal aortic aneurysm (AAA), a condition primarily affecting older men, is often asymptomatic but becomes life-threatening if rupture occurs. While AAA risk factors such as age, gender, and smoking are well-studied, physical activity (PA) may also play a critical role in managing AAA progression, though this relationship remains understudied. This scoping review aims to synthesize current knowledge on the impact of PA on AAA, examining safety, physiological effects, and potential protective effects against AAA progression.

Intermediate filaments (IFs) play a major role in determining and maintaining cell shape and anchoring intracellular organelles in place, in the tissues and organs of several species, starting from the early stages of development. This study was aimed at the immunohistochemical investigation of the presence, cellular localization and temporal distribution of the intermediate filaments keratin 8 (CK8), keratin 18 (CK18), keratin 19 (CK19), vimentin, desmin and laminin, all of which contribute to the formation of the cytoskeleton in the rat mammary gland during pregnancy, lactation and involution. On days 7, 14 and 21 of pregnancy (pregnancy period), on day 7 post-delivery (lactation period) and on day 7 post-weaning (involution period), under ketamine hydrochloride (Ketalar-Pfizer) (90 mg/kg) anesthesia, two mammary glands were fully excised from the abdominal region.
