OBJECTIVE Acute cholecystitis is a common disease, and laparoscopic surgery is the standard of care. BACKGROUND Optimal timing of surgery for acute cholecystitis remains controversial: either early surgery shortly after hospital admission or delayed elective surgery after a conservative treatment with antibiotics. METHODS The ACDC ("Acute(More)
Chemotherapeutic drugs cause DNA damage and kill cancer cells mainly by apoptosis. p53 mediates apoptosis after DNA damage. To explore the pathway of p53-dependent cell death, we investigated if p53-dependent apoptosis after DNA damage is mediated by the CD95 (APO-1/Fas) receptor/ligand system. We investigated hepatoma, gastric cancer, colon cancer, and(More)
Chemotherapeutic drugs are cytotoxic by induction of apoptosis in drug-sensitive cells. We investigated the mechanism of bleomycin-induced cytotoxicity in hepatoma cells. At concentrations present in the sera of patients during therapy, bleomycin induced transient accumulation of nuclear wild-type (wt) p53 and upregulated expression of cell surface CD95(More)
The CD95 (APO-1/Fas) system is an important mediator of T-cell cytotoxicity. We investigated this system in 22 hepatocellular carcinomas (HCCs) from patients. All HCCs had partially or completely lost the expression of the CD95 receptor constitutively expressed by normal liver cells and might thus evade CD95-mediated killing. We also considered a new(More)
BACKGROUND & AIMS The course of hereditary hemochromatosis may depend on the degree of iron overload and the time of therapeutic intervention. This analysis evaluates the impact of early diagnosis and iron removal on survival and complications in hereditary hemochromatosis. METHODS A Cohort of 251 patients with hemochromatosis was followed up for 14.1 +/-(More)
BACKGROUND Wilson's disease is a rare inborn disease related to copper storage, leading to liver cirrhosis and neuropsychological deterioration. Clinical data on larger cohorts are limited owing to low disease frequency. OBJECTIVE AND METHODS We performed a retrospective analysis of 163 patients with Wilson's disease, examined at the University of(More)
Multidrug resistance-associated protein 3 (MRP3; symbol ABCC3), has been shown to mediate ATP-dependent transport of organic anions including 17beta-glucuronosyl estradiol, glucuronosyl bilirubin, monovalent, and sulfated bile salts. MRP3 mRNA expression was reported in rat intestine suggesting a role of MRP3 in the intestinal transport. We examined the(More)
The aim of this study was to determine whether anti-p53 antibodies are of clinical significance as a serological marker in the diagnosis and monitoring of malignancies. A total of 1874 serum samples from 591 patients with various types of cancer, esophageal, gastric, colorectal, pancreatic, hepatocellular, breast, and urogenital cancer, and 436 control(More)
Leptin is a pleiotropic hormone believed to regulate body weight. Its function in wasting during inflammatory disease in humans is unknown. We studied the effect of repeated tumor necrosis factor (TNF) infusion on serum leptin levels in six patients with solid tumors. TNF infusion on day 1 resulted in an increase in serum leptin levels from 3.1 (SEM +/-(More)
Acute and chronic hepatitis C virus (HCV) infection remains a serious health problem worldwide, however, there has been advancement in the treatment of HCV infection due to standard treatment using pegylated interferon and ribavirin. The literature indicates that therapy for HCV is becoming more individualized. In addition to considering genotype and viral(More)
