Fatty liver is a common metabolic disorder of dairy cows during the transition period. Historically, the diagnosis of fatty liver has involved liver biopsy, biochemical or histological examination of liver specimens, and ultrasonographic imaging of the liver. However, more convenient and noninvasive methods would be beneficial for the diagnosis of fatty liver in dairy cows. The plasma metabolic profiles of dairy cows with fatty liver and normal (control) cows were investigated to identify new biomarkers using (1)H nuclear magnetic resonance. Compared with the control group, the primary differences in the fatty liver group included increases in β-hydroxybutyric acid, acetone, glycine, valine, trimethylamine-N-oxide, citrulline, and isobutyrate, and decreases in alanine, asparagine, glucose, γ-aminobutyric acid glycerol, and creatinine. This analysis revealed a global profile of endogenous metabolites, which may present potential biomarkers for the diagnosis of fatty liver in dairy cows.

Background: Excessive fluoride exposure leads to increased oxidative stress and lipid peroxidation, causing harmful effects on the metabolic organs in the human body. Betanin, a pigment obtained from beetroot, is seen to have powerful anti-inflammatory and antioxidant. The study was conducted to determine the role of betanin in fluoride induced hepato-renal toxicity in Wistar rats.

Mitochondrial endonuclease G (EndoG) contributes to chromosomal degradation when it is released from mitochondria during apoptosis. It is presumed to also have a mitochondrial function because EndoG deficiency causes mitochondrial dysfunction. However, the mechanism by which EndoG regulates mitochondrial function is not known.

This study sought to identify challenges to the diagnosis, treatment and management of people living with MASLD and MASH and understand the key barriers to adopting relevant clinical guidelines.
Methods: A real-world, cross-sectional study (BARRIERS-MASLD) consisting of a quantitative survey and qualitative interviews of physicians in France, Germany, Italy, Spain and the United Kingdom was conducted from March to September 2023.

Although metabolic dysfunction-associated steatotic liver disease (MASLD), previously termed nonalcoholic fatty liver disease, has become the most common chronic liver disorder, its complex pathophysiology has not been fully elucidated up to date. A correlation between elevated sympathetic activation and MASLD has been highlighted in recent preclinical and clinical studies. Furthermore, increased sympathetic activity has been associated with the main mechanisms involved in MASLD, such as lipid accumulation in the liver, insulin resistance, and metabolic dysregulation, while it has been also correlated with the progression of MASLD, leading to liver fibrosis.
