In this overview of vascular changes of the liver, variations in the liver vessels are discussed, in addition to congenital malformations such as Abernethy malformation, patent ductus venosus Arantii and hereditary hemorrhagic telangiectasia (OslerWeber-Rendu disease). Particular attention is paid to focal liver lesions, especially focal nodular hyperplasia (FNH), but also other solid tumours that develop as a result of altered liver vascularisation. The article focuses on the ultrasonic appearances and changes of the liver, depicted in B-mode sonography, Doppler studies and in contrast-enhanced ultrasonography (CEUS). The clinical manifestations of these conditions associated with other organ systems are also highlighted.

Toxic effects of herbicide atrazine (ATR) have been evaluated in various aquatic organisms, but our understanding of its potential impacts in reptile species remains limited. In this study, the functional performances, and gut microbiota and liver metabolite alterations of ATR-exposed Mauremys sinensis juveniles were measured to evaluate its potential toxic effects in turtles. ATR exposure had no impact on the growth rate, but would allow turtles to right themselves more quickly.

Studies of the aging transcriptome focus on genes that change with age. But what can we learn from age-invariant genes-those that remain unchanged throughout the aging process? These genes also have a practical application: they can serve as reference genes in expression studies. Reference genes have mostly been identified and validated in young organisms, and no systematic investigation has been done across the lifespan.

Background/Aims: To evaluate invasive treatment outcomes for hepatocellular carcinoma (HCC) in patients aged over 90 years. Materials and methods: Twenty-six patients were included. Information on backgrounds, course of treatment, outcomes, and changes in Child-Pugh (CP) score and performance status (PS), as well as a comparison of treatment-related complications and 2-year survival after treatment, were retrospectively examined and compared with 311 patients aged under 90 years who were matched under the same conditions.

The interplay between diet-induced obesity and gastrointestinal dysfunction is an evolving area of research with far-reaching implications for understanding the gutbrain axis interactions. In their study, Ramírez-Maldonado et al. employ a cafeteria (CAF) diet model to investigate the effects on gut microbiota, enteric nervous system (ENS) integrity and function, and gastrointestinal motility in mice.

Nonalcoholic fatty liver disease (NAFLD) is the most prevalent chronic liver condition, characterized by a spectrum that progresses from simple hepatic steatosis to nonalcoholic steatohepatitis, which may eventually lead to cirrhosis and hepatocellular carcinoma. The precise pathogenic mechanisms underlying NAFLD and its related metabolic disturbances remain elusive. Epigenetic modifications, which entail stable transcriptional changes without altering the DNA sequence, are increasingly recognized as pivotal.
