Background: The pathological mechanism of sudden death in healthy persons following incidental ethanol intoxication has not yet been fully elucidated and might be underlain by cardiogenic causes.
Aim: Histological assessment of the myocardium in lethal ethanol intoxication. The analysis was based on a histological assessment of specimens of the myocardium obtained from the hearts of 30 deceased males within the age range 29-45 years.
Methods: The material for the study was taken from the myocardium of the anterior wall of the left ventricle and interventricular septum of the heart. The fixation material was first examined according to the standard histological procedure and subsequently subjected to a morphometric examination, which assessed the number of cardiomyocytes, their area, circumference, and circular deviation.
Results: The examination showed an increase in the area and circumference of cardiomyocytes, as well as fragmentation and segmentation of cardiomyocytes with a significant enlargement of cell nuclei. Additionally, it revealed the presence of lymphocytic cells in several cases.Conclusions: The obtained findings indicate a harmful influence of alcohol on the myocardium.

Background: The efficacy of bone marrow aspirate concentrate (BMAC) in promoting bone-tendon interface (BTI) healing without any carriers remains a subject of debate.
Purpose: To evaluate BMAC effects with different carriers on tendon regeneration in a rabbit model of chronic rotator cuff tear.
Study Design: Controlled laboratory study.

Background & Objectives: Differentiation of histologic subtypes of appendiceal mucoceles may prove to be difficult on computed tomography (CT). The main objective of this study was to identify the CT features of mucocele of the appendix and correlate the imaging findings with histopathology in inflammatory, benign, and malignant neoplastic lesions, and whether these entities can be accurately differentiated on CT imaging.
Materials And Methods: CT scans of 31 patients with diagnosis of appendiceal mucocele were retrospectively reviewed and compared with histopathology.

This study aims to develop an end-to-end deep learning (DL) model to predict neoadjuvant chemotherapy (NACT) response in osteosarcoma (OS) patients using routine magnetic resonance imaging (MRI). We retrospectively analyzed data from 112 patients with histologically confirmed OS who underwent NACT prior to surgery. Multi-sequence MRI data (including T2-weighted and contrast-enhanced T1-weighted images) and physician annotations were utilized to construct an end-to-end DL model.

Lower urinary tract symptoms (LUTS) significantly affect patient quality of life. Treatment options for bladder outlet obstruction (BOO) due to benign prostatic hyperplasia (BPH) (a common cause of LUTS) are insufficient to relieve discomfort. As the incidence of BPH is increasing, new pharmacological targets for LUTS treatment are required.

The nitrate pollution has become an increasingly serious environmental problem worldwide, and the toxic effects of elevated nitrate levels in the environment on aquatic animals remain to be elucidated. The purpose of the present study was to investigate the mechanisms of liver injury to tadpoles after exposure to nitrate from embryonic to metamorphic climax and to assess the recovery process of liver function after cessation of exposure. In the group with continuous nitrate exposure, the livers and thyroid of tadpoles showed remarkably histological lesions, of this with structural disorganization of the hepatocytes, cellular atrophy, and fibrosis, as well as significant reduction in the follicular and colloidal area of the thyroid.
