Altered circadian hemodynamic and renal function in cirrhosis

Seasonal and circadian variations of hemodynamic and electrocardiographic parameters in telemetered beagle dogs

Hemodynamic derangement and cardiac dysfunction in cirrhosis.

Liver cirrhosis is characterized by a long course that lasts between 15 and 20 years. The natural history of this disease depends mainly on the occurrence and progression of single complications which are today more fully understood and therefore more treatable. More specifically, those complications involving hemodynamic mechanisms have been extensively studied in recent years. Indeed, the mec...

Hemodynamic alterations in cirrhosis and portal hypertension

Portal hypertension (PHT) is associated with hemodynamic changes in intrahepatic, systemic, and portosystemic collateral circulation. Increased intrahepatic resistance and hyperdynamic circulatory alterations with expansion of collateral circulation play a central role in the pathogenesis of PHT. PHT is also characterized by changes in vascular structure, termed vascular remodeling, which is an...

Renal Function and Hemodynamic Study in Obese Zucker Rats

OBJECTIVES To investigate the renal function and hemodynamic changes in obesity and hyperinsulinemia which are characteristics of type II diabetes. METHODS Studies were carried out in two groups of female Zucker rats. Group 1 rats were obese Zucker rats with hereditary insulin resistance. Group 2 rats were lean Zucker rats and served as controls. In comparison with lean Zucker rats, obese Zuc...

Circadian regulation of renal function and potential role in hypertension.

PURPOSE OF REVIEW Previous studies have shown that a variety of specific renal functions exhibit circadian oscillations. This review aims to provide an update on the molecular mechanisms underlying circadian rhythms in the kidney, and to discuss how dysregulation of circadian rhythms can interfere with kidney function. RECENT FINDINGS The molecular mechanism responsible for generating and mai...
