Twenty-nine patients with primary sclerosing cholangitis were reviewed. Males predominated (2:1). Seventy-six per cent presented with cholestasis and cholangitis, 17% with cirrhosis and portal hypertension, and 7% were asymptomatic, presenting with a raised serum alkaline phosphatase. The serum immunoglobulin IgM concentration was raised in 45% of the(More)
Copper plays an essential role in promoting angiogenesis. Tumors that become angiogenic acquire the ability to enter a phase of rapid growth and exhibit increased metastatic potential, the major cause of morbidity in cancer patients. We report that copper deficiency induced by tetrathiomolybdate (TM) significantly impairs tumor growth and angiogenesis in(More)
XIAP is a potent suppressor of apoptosis that directly inhibits specific members of the caspase family of cysteine proteases. Here we demonstrate a novel role for XIAP in the control of intracellular copper levels. XIAP was found to interact with MURR1, a factor recently implicated in copper homeostasis. XIAP binds to MURR1 in a manner that is distinct from(More)
BACKGROUND Endoscopic stenting is an effective method of relieving biliary obstruction in patients with unresectable malignancy. If this fails, optimal management is controversial. Percutaneous insertion of plastic or mesh metal stents has been advocated. AIM To review the outcome of percutaneous plastic stents and compare this with contemporary data from(More)
Twenty-five patients with stenosis of the vena cava (21) and other large veins (4) have been treated with self-expanding Gianturco metallic stents. Eighteen patients had superior vena cava syndrome. In 17, the stricture was due to malignant superior vena cava compression recurrent after maximum tolerance radiotherapy and/or chemotherapy. In 16 of these(More)
Ceruloplasmin (CP), the major plasma anti-oxidant and copper transport protein, is synthesized in several tissues, including the brain. We compared regional brain concentrations of CP and copper between subjects with Alzheimer's disease (AD, n = 12), Parkinson's disease (PD, n = 14), Huntington's disease (HD, n = 11), progressive supranuclear palsy (PSP, n(More)
A new type of biliary stent was inserted in 45 patients with symptomatic biliary strictures, 40 malignant and five benign. The stent is made of stainless steel woven into a tubular mesh. It is introduced in compressed form on a 7- or 9-F delivery catheter and released at the site of the stricture. Fully open, the stent has an internal diameter of 1 cm. The(More)
Preclinical and in vitro studies have determined that copper is an important cofactor for angiogenesis. Tetrathiomolybdate (TM) was developed as an effective anticopper therapy for the initial treatment of Wilson's disease, an autosomal recessive disorder that leads to abnormal copper accumulation. Given the potency and uniqueness of the anticopper action(More)
Patients with liver disease frequently have impaired blood coagulation. The optimal method for liver biopsy in this situation is not established. To investigate this issue we randomised 117 patients with impaired blood coagulation, in whom liver biopsy was required, to receive either transjugular or plugged-percutaneous biopsy. Seventeen patients were(More)
