Objectives Amino acids play an essential role in protein synthesis, metabolism and survival of pancreatic acini. Adequate nutritional support is important for acute pancreatitis treatment. However, high concentrations of arginine and lysine may induce acute pancreatitis. The study aimed to identify the most suitable L-amino acids as safe energy sou...

Plasma amino acid levels are altered upon many pathological conditions including acute pancreatitis. It is unclear whether amino acids can be used as specific biomarker of acute pancreatitis severity or recovery. Development of acute pancreatitis is associated with mitochondrial dysfunction and decreased cytosolic ATP level. Sodium pyruvate is cons...

Background. Assessment of cell viability is crucial in cell studies. Testing plasma membrane integrity is a traditional approach of evaluating cell viability. Mitochondrial functional capacity closely correlates with plasma membrane integrity and overall cell health. This study aimed to investigate whether any aspect of mitochondrial adaptive capac...

Amino acids play an essential role in protein synthesis, metabolism and survival of pancreatic acinar cells. Adequate nutritional support is important for acute pancreatitis treatment. However, some amino acids, such as arginine and lysine, are toxic for pancreatic acinar cells in high concentrations. The study aimed to select the candidate amino a...

Objectives: The objective of this study was to test whether pyruvate and glutamine affect the ethanol and cholecystokinin (CCK) effects on the mitochondrial function, viability, and morphology of rat pancreatic acini. Methods: Respiration was measured with Clark oxygen electrode. Mitochondrial membrane potential, reduced nicotinamide adenine din...

During glutamine catabolism is produced ammonia, which can be toxic to cells. In hepatic encephalopathy neuron mitochondria ammonia causes the formation of free radicals, the opening of the mitochondrial permeability transition pore, oxidative phosphorylation disruption and swelling. It is still unknown whether the utilization of glutamine in the m...
