ATP-binding cassette transporters (ABC) G1 and ABCA1 are membrane cholesterol transporters and have been implicated to mediate cholesterol efflux from cells in the presence of high density lipoproteins and its major protein constituent apolipoprotein A-I, respectively. We previously demonstrated that unsaturated fatty acids suppress the stimulatory effects(More)
PURPOSE To identify factors affecting stent occlusion after stent placement in the portal vein in patients with malignant portal vein invasion. MATERIALS AND METHODS Forty patients were studied. Twenty-three patients had hepatocellular carcinoma, nine patients had pancreatic cancer, and eight patients had bile duct cancer. Stents were placed in the portal(More)
PURPOSE To evaluate the clinical usefulness of portal venous stent placement in patients with pancreatic or biliary neoplasms invading portal veins and causing portal hypertension. MATERIALS AND METHODS Thirteen patients underwent portal venous stent placement because of gastrointestinal bleeding (n = 8), risk of gastroesophageal varix rupture (n = 4),(More)
Human gingival fibroblasts from six patients who developed gingival hyperplasia as a result of nifedipine medication and five who did not were studied for the effects of calcium-channel blockers (nifedipine, diltiazem, verapamil and nicardipine) on cell proliferation, DNA synthesis and collagen synthesis. Phenytoin was used as a positive control. The(More)
The authors performed a serial study of a patient with mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke-like syndrome (MELAS) who presented with diffusion-weighted MRI (DWI). DWI demonstrated a higher apparent diffusion coefficient in the lesion than in the control region during the acute stage of stroke. Vasogenic edema is present in(More)
In the present study we identified the epitopes of antibodies against amyloid beta-(1-42)-peptide (Abeta1-42): 4G8 reacted with peptides corresponding to residues 17-21, 6F/3D reacted with peptides corresponding to residues 9-14, and anti 5-10 reacted with peptides corresponding to residues 5-10. The study also yielded some insight into the Abeta1-42(More)
We examined whether the serum matrix metalloproteinase-2 (MMP-2) level and MMP-2 density could be predictors of the development and extension of prostate cancer. Serum samples were collected before any clinical treatment from 98 patients with prostate cancer and from 76 patients with benign prostatic hyperplasia (BPH). Control sera were obtained from 70(More)
AIM AND METHODS Epitope analysis of sera from 20 patients with myeloperoxidase anti-neutrophil cytoplasmic antibody- (MPO-ANCA) associated glomerulonephritis was examined by Western blotting using a panel set of recombinant deletion mutants of MPO. Sera from 19 patients reacted with recombinants of MPO heavy chain, whereas no serum reacted with the light(More)
A case of Bellini duct carcinoma is reported. A left renal tumor was detected by abdominal computerized tomography in a 76-year-old male, although he had no symptoms, such as hematuria, weight loss or flank pain. Radical nephrectomy was performed under the diagnosis of renal cell carcinoma in the left kidney. Macroscopic examination of the resected kidney(More)
