Tanshinone IIA (TSA), a pharmacologically active component isolated from Danshen, may prevent cardiovascular diseases due to its anti-inflammatory, anti-oxidative, and anti-adipogenic effects. Porphyromonas gingivalis, a major periodontal pathogen, may contribute to the progression of atherosclerosis. Here, we studied the effects of TSA on atherosclerosis in ApoE(-/-) mice with P. gingivalis infection. Eight-week-old ApoE(-/-) mice were randomized to (a) phosphate-buffered saline (PBS), (b) P. gingivalis, and (c) P...

BACKGROUND AND AIM: Chronic HCV infection is associated with several extrahepatic manifestations (EHMs). Data on the effect of sustained virological response (SVR) on the risk of EHMs are limited. METHODS: We conducted a retrospective cohort study using data of patients from the US Veterans Affairs HCV Clinical Case Registry who had a positive HCV RNA test (10/1999-08/2009). Patients receiving interferon-based antiviral therapy (AVT) were identified. SVR was defined as negative HCV RNA at least 12 weeks after end of AVT...

BACKGROUND: Until recently, transplantation from hepatitis C positive donors was relatively contraindicated as eradication of active hepatitis C previously required an interferon-based regimen which has been associated with rejection in solid organ transplantation. New interferon-free treatment regimens for hepatitis C have fewer adverse events and higher cure rates than interferon-based regimens. Interferon-free regimens have been shown to be safe in the liver transplantation literature but little is known about the safety and efficacy of treatment in heart transplantation...

BACKGROUND AND AIM: Circulating fibroblast activation protein (cFAP) is a constitutively active enzyme expressed by activated fibroblasts that has both dipeptidyl peptidase and endopeptidase activities. We aimed to assess the correlation between cFAP activity and antigen levels and to compare variations in levels. METHODS: In plasma of 465 control individuals, 368 patients with coronary heart disease (CHD) and 102 hepatitis C virus (HCV) infected patients with severe liver disease before and after liver transplant, cFAP activity levels were measured with a newly developed cFAP activity assay...

Liver fibrosis is common, particularly in human immunodeficiency virus infected (HIV+) people. HIV+ people have excess congestive heart failure (CHF) risk compared to uninfected people. It remains unknown if stage of liver fibrosis influences the CHF risk or if HIV or hepatitis C virus (HCV) infection modifies this association. Our objectives were to assess whether: 1) stage of liver fibrosis is independently associated with incident CHF; 2) the association between stage of liver fibrosis and incident CHF is modified by HIV/HCV status...

The emergence of improved antiretroviral therapy has increased the life expectancy of human immunodeficiency virus (HIV)-infected individuals, though there is an increased susceptibility to developing cardiovascular diseases (CVD). The risk for CVD is purported to be even higher among people with HIV and hepatitis C virus (HCV) co-infection because of the increased inflammatory response, which may synergistically impact CV risk; however, studies comparing CV outcomes between HIV alone and HIV/HCV individuals have been discordant...

A captive 17-year old female Malayan tapir (Tapirus indicus) aborted a fetus with a crown rump length of 19cm in early pregnancy. The fetus showed an early state of mummification. Histologically, a multifocal mononuclear encephalitis, myocarditis and periportal hepatitis was present indicating a possible protozoal cause of abortion. Although immunohistologically, Neospora (N.) caninum antigen could not be demonstrated, N. caninum DNA was detected by Polymerase Chain Reaction (PCR) in brain, heart, liver and lung of the fetus...

BACKGROUND: High plasma concentration of low-density lipoprotein cholesterol (LDL-c) plays a significant role in the incidence of atherosclerosis and coronary heart diseases (CHD). MATERIALS AND METHODS: The purpose of this study was to investigate the mechanism by which citrus flavonoids, naringenin regulate the LDL receptor (LDLr) gene in human liver using the human hepatoma cell line, HepG2 as a model. RESULTS: Time-course transient transfection of HepG2 cells with luciferase reporter-gene constructs incorporating the promoters of SREBP-1a,-1c, -2 and LDLr, revealed that in lipoprotein-deficient medium (LPDM), only SREBP-1a promoter activity was increased significantly after 4h exposure to 200μM naringenin respectively...

Hepatic mitochondrial function, APOC-III and LPL are potential targets for TG lowering drugs. After three weeks of dietary treatment with the compound 2-(tridec-12 -yn-1-ylthio) acetic acid (1-triple TTA), the hepatic mitochondrial FA oxidation increased more than 5-fold in male Wistar rats. Gene expression analysis in liver showed significant downregulation of APOC-III, and upregulation of LPL and the VLDL receptor. This led to lower hepatic (53 %) and plasma (73 %) TG levels. Concomitantly liver-specific biomarkers related to mitochondrial biogenesis and function (mitochondrial DNA, citrate synthase activity and cytochrome c and Tfam gene expression) were elevated...

INTRODUCTION: Cardiovascular complications are the most important cause of mortality in patients with ESKD, such as coronary artery disease, left ventricular hypertrophy, heart failure and arrhythmia. Other well-known risk factors, such as diabetes mellitus, hypertension and dyslipidemia are prevalent in ESKD, yet they are not sufficient enough to explain the high prevalence of cardiovascular mortality, hence searching for other hidden risk factors to explain this high prevalence is of an utmost importance...

OBJECTIVES: The objective of this clinical trial was to evaluate the long-term effect of endothelin receptor antagonism with bosentan on the morbidity and mortality of patients with severe chronic heart failure. BACKGROUND: Endothelin may play a role in heart failure, but short-term clinical trials with endothelin receptor antagonists have reported disappointing results. Long-term trials are lacking. METHODS: In 2 identical double-blind trials, we randomly assigned 1,613 patients with New York Heart Association functional class IIIb to IV heart failure and an ejection fraction <35% to receive placebo or bosentan (target dose 125 mg twice daily) for a median of 1...

Ischemic heart disease is the main cause of death worldwide and is accelerated by increased levels of low-density lipoprotein cholesterol (LDL-C). Proprotein convertase subtilisin/kexin type 9 (PCSK9) is a potent circulating regulator of LDL-C through its ability to induce degradation of the LDL receptor (LDLR) in the lysosome of hepatocytes. Only in the last few years, a number of breakthroughs in the understanding of PCSK9 biology have been reported illustrating how PCSK9 activity is tightly regulated at several levels by factors influencing its transcription, secretion, or by extracellular inactivation and clearance...

Because hepatic dysfunction is common in patients with heart failure (HF), the Model for End-Stage Liver Disease (MELD) may be attractive for risk stratification. Although alternative scores such as the MELD-XI or MELD-Na may be more appropriate in HF populations, the short-term clinical implications of these in patients with acute heart failure (AHF) are unknown. The MELD-XI and MELD-Na were calculated at baseline in 453 patients with AHF in the DOSE-AHF and ROSE-AHF trials. The correlations and associations for each score with cardiorenal biomarkers, short-term end points at 72 hours including worsening renal function and clinical events to 60 days were determined...
