A positive correlation between absence of residual tumor at resection margins and long-term survival in the treatment of hilar bile duct carcinoma has encouraged some surgeons to use a more radical approach, including liver/portal vein resection and combined pancreatoduodenectomy. However, if liver resection is associated with significant morbidity and(More)
We investigated the potential association of tumor necrosis factor-alpha (TNF-alpha) promoter polymorphisms with cancers. The study included 169 patients with gastric cancer, uterine cervical cancer, colorectal cancer, or renal cell carcinoma and 92 healthy controls. The -308 and -238 polymorphisms in the TNF-alpha promoter were analyzed by PCR-restriction(More)
Reliable epidemiologic data are essential for formulating effective policy to control rotavirus disease through immunization. The objective of this study was to describe the epidemiology of rotavirus diarrhea in a population-based cohort of children under 3 years of age residing in Abu Homos, Egypt, in 1995-1996. Rotavirus diarrhea incidence rates (episodes(More)
Computed tomography (CT) and ultrasonography (US) are ideally suited for demonstrating urachal remnant diseases. A patent urachus is demonstrated at longitudinal US and occasionally at CT as a tubular connection between the anterosuperior aspect of the bladder and the umbilicus. An umbilical-urachal sinus manifests at US as a thickened tubular structure(More)
OBJECTIVE The purpose of this study was to histologically classify intramural nodules associated with xanthogranulomatous cholecystitis and to evaluate the radiologic findings for each type of nodule. MATERIALS AND METHODS Pathologic slides and radiologic studies including 14 sonographic and 16 CT examinations in 19 patients (12 men, seven women; mean(More)
Laccase produced by Coriolus hirsutus was purified to electrophoretic homogeneity by acetone precipitation, DEAE Sepharose CL-6B, Sephacryl S-200 HR, Hitrap SP, and Mono S chromatography. The purification was 14.5-fold with an overall yield of 32.3%. The enzyme is a monomeric glycoprotein with 11% carbohydrate content, an isoelectric point of 7.4, and a(More)
To develop a reliable and valid psychiatric self-rating scale for use in medical practice, the authors modified Derogatis' Symptom Check List-90-R (SCL-90-R) and designed a shorter form, named Brief Symptom Rating Scale (BSRS). The BSRS comprises 50 items, which best reflect the original ten symptom dimensions and three indices of psychopathology from the(More)
We analyzed the results from nationwide surveillance of avian influenza (AI) from birds in South Korea's major wild bird habitats and the demilitarized zone of South Korea, 2003-2008. Of 28,214 fecal samples analyzed, 225 yielded influenza viruses, for a prevalence of 0.8%. Hemagglutinin (HA) subtypes H1-H12 and all nine neuraminidase (NA) subtypes were(More)
Recently, glucose deprivation-induced oxidative stress has been shown to cause cytotoxicity, activation of signal transduction (i.e., ERK1, ERK2, JNK, and Lyn kinase), and increased expression of genes associated with malignancy (i.e., bFGF and c-Myc) in MCF-7/ADR human breast cancer cells. These results have led to the proposal that intracellular(More)
Sequence analysis of the hemagglutinin (HA) gene of five Korean H9N2 avian influenza virus (AIV) isolates showed that these viruses were closely related and possibly came from the same source. Phylogenetic analysis of the HA1 subunit of H9 subtype isolates revealed that Korean AIV isolates were different from isolates from the poultry markets in Hong Kong(More)
