Transjugular intrahepatic portosystemic shunt: impact on systemic haemodynamics and renal and cardiac function in patients with cirrhosis.
CONCLUSIONS: TIPS increases CBV by increasing CO and SV, whereas HR is initially unaltered. These results indicate an inability to increase the heart rate in response to a hemodynamic challenge that only partially increases CBV after TIPS. These changes, however, are sufficient for improving renal function. PMID: 29074483 [PubMed - as supplied by publisher]

Insulin Regulation of Hepatic Lipid Homeostasis
Compr Physiol. 2023 Jun 26;13(3):4785-4809. doi: 10.1002/cphy.c220015.ABSTRACTThe incidence of obesity, insulin resistance, and type II diabetes (T2DM) continues to rise worldwide. The liver is a central insulin-responsive metabolic organ that governs whole-body metabolic homeostasis. Therefore, defining the mechanisms underlying insulin action in the liver is essential to our understanding of the pathogenesis of insulin resistance. During periods of fasting, the liver catabolizes fatty acids and stored glycogen to meet the metabolic demands of the body. In postprandial conditions, insulin signals to the liver to store exc...
