OBJECTIVES The present study was performed to evaluate the impact of the international unit standard for measuring HCV RNA in the management of patients with chronic hepatitis C virus (HCV) infection. METHODS The three assays used were Amplicor Monitor PCR, the National Genetics Institute PCR assay, and branched chain DNA. HCV RNA was measured at four(More)
BACKGROUND Development of quality-control criteria to ensure reproducibility of microarray results for potential clinical application is still in its infancy. METHODS In the present studies we developed quality-control criteria and evaluated their effect in microarray data analysis using total RNA from cell lines, frozen tumors, and a commercially(More)
A pretest-posttest, repeated-measures design was used to evaluate the effects of two stress management interventions on a battery of outcomes derived from a psychoneuroimmunological (PNI) framework. The effects of cognitive-behavioral relaxation training groups (CBSM) and social support groups (SSG) were compared with a WAIT-listed control group on the(More)
Di-n-octyl phthalate (DOP) is the straight chain isomer of di(2-ethylhexyl) phthalate (DEHP) which is a widely used plasticizer and an environmental contaminant. DEHP is a strong inducer of peroxisome proliferation in rat liver. This is significant since other compounds which are strong inducers of peroxisome proliferation have been reported to be weak(More)
BACKGROUND Adenocarcinoma of the fallopian tube is a rare tumor with a poor prognosis. Whether these carcinomas possess any genetic changes that contribute to their malignant behavior is unknown and to date few studies regarding the molecular pathogenesis of these tumors have been reported. In adenocarcinoma of the endometrium, mutations in the first exon(More)
The demonstration of immunoglobulin or T-cell receptor gene rearrangements in human lymphoproliferative processes with the use of DNA hybridization has gained great popularity as a sensitive laboratory adjunct to diagnostic hematopathology. The fact that nearly all B- or T-cell malignant lymphomas and leukemias have one or more rearranged antigen receptor(More)
The present study was conducted to evaluate the relationship between biochemical, virological, and histological response during the course of interferon therapy. Ninety consecutive patients with well-documented chronic hepatitis C virus (HCV) were treated with 5 MU of interferon alfa-2b three times weekly for 6 months. Liver biopsy was performed, and serum(More)
Cytologic evaluation of lymph node fine-needle aspirates and serous effusions is a rapid and useful means for establishing the diagnosis of a variety of lymphoproliferative disorders. However, in some instances, cytologic findings are not sufficient to establish a diagnosis of lymphoma, thus necessitating the use of ancillary procedures, the most frequent(More)
Focal glomerulosclerosis (FGS) has been considered as HIV-associated nephropathy, a specific renal complication of infection. To determine whether renal disease in HIV infected patients has one highly prevalent pathologic expression, and whether renal parenchymal viral genomic incorporation affects pathologic outcome, we reviewed renal biopsies performed at(More)
The administration of high-dose valproic acid (VPA) (750 mg per kg) consistently produced significant microvesicular steatosis in mature Sprague-Dawley rats after 48 hr. Similar changes occurred in animals pretreated with phenobarbital which received a lower dose of VPA (350 mg per kg), but no steatosis was seen in animals treated with the low-dose VPA(More)
