background the identification of the dorsal sector of the liver and its detailed vascular anatomy is of primary importance for surgical practice and segmental transcatheter arterial chemoembolization. objectives this study aimed to investigate the feeding arteries of tumors in dorsal sector of the liver. patients and methods computed tomography (ct) and digital subtraction angiography (dsa) ima...

coincidental occurrence of hepatocellular carcinoma (hcc) and cholangiocarcinoma, known as “collision tumors”, within a cirrhotic liver is rare. herein, we report a case of liver transplantation (lt) in a patient with such collision tumors. our patient was a 56-year-old woman with hepatitis c virus-related cirrhosis and 2 focal hepatic lesions, measuring 1.5 and 3 cm, in the liver segments 8 an...

objective(s):diabetes plays an important role in the induction of the liver injury. grape seed proanthocyanidin (gsp) have a wide range of medicinal properties against oxidative stress. in this study we evaluated antioxidant effects of gsp on liver in streptozotocin-induced diabetic rats. materials and methods: thirty male sprague–dawley rats were divided into three groups: control, untreated d...

noise-induced hearing loss (nihl) is the most common complication of long-term noise exposure, though there  are  some  other  complications  due  to  exposure  to  noise.  metabolic  complications  of  the  noise exposure are being evaluated in recent studies. we aimed to assess the relationship between nihl and lipid profile, and fasting blood sugar (fbs). in this cross-sectional  study, 462 ...

Sketches are a commonly used tool in the early stages of design. Our previous system, ASSIST(Alvarado, 2000), lets users sketch in a natural fashion and recognizes mechanical systems. ASSIST also interfaces with a simulation tool to show users their sketch in action. ASSISTANCE(Oltmans, 2001) builds on ASSIST by allowing the user to use additional sketching and voice input to describe the behav...

UNLABELLED Patient selection is crucial for the success of ventricular assist devices as a bridge to heart transplantation. PURPOSE The objective of this study was to identify preoperative markers for survival and end-organ recovery in patients having a ventricular assist device. METHODS A retrospective study was performed on 32 severely ill patients with end-stage cardiac failure being mec...

The liver is one of the most complex and metabolically active organs in the body and performs many detoxification and protein synthetic functions that are essential to life. Extracorporeal bioartificial liver (BAL) systems consisting of functioning, viable hepatocytes may provide temporary support for patients with acute hepatic failure and save the lives of patients awaiting orthotopic liver t...

Objective(s): Hepatic ischemia/reperfusion injury (IRI) is one of the major causes of hepatic failure during liver transplantation, trauma, and infections. The present study investigated the protective effect of intra-portal administration of 2-methoxycinnamaldehyde (2-MCA) on hepatic IRI in rats. Materials and Methods: Twenty-four rats ...

Left ventricular assist device therapy has radically improved congestive heart failure survival with smaller rotary pumps. The driveline used to power today's left ventricular assist devices, however, continues to be a source of infection, traumatic damage, and rehospitalization. Previous attempts to wirelessly power left ventricular assist devices using transcutaneous energy transfer systems h...

Glucuronidation of carboxylic acid compounds results in the formation of electrophilic acyl glucuronides. Because of their polarity, carrier-mediated hepatic transport systems play an important role in determining both intra- and extrahepatic exposure to these reactive conjugates. We have previously shown that the hepatic membrane transport of 1-O-gemfibrozil-beta-D-glucuronide (GG) is carrier-...
