Mitochondrial neurogastrointestinal encephalomyopathy (MNGIE) is an autosomal recessive disorder defined clinically by severe gastrointestinal dysmotility; cachexia; ptosis, ophthalmoparesis, or both; peripheral neuropathy; leukoencephalopathy; and mitochondrial abnormalities. The disease is caused
The purpose of this study was to investigate the effects of isolates of noncytopathic type 2 Bovine viral diarrhea virus (ncpBVDV-2) of high and low virulence on the proliferation of bone marrow progenitor cells. Holstein calves 6 to 7 mo old and BVDV-naïve were inoculated intranasally with a BVDV
Three Brazilian isolates of bovine viral diarrhea virus (BVDV), antigenically distinct from the standard North American isolates, were selected to immunize BALB/c mice in order to obtain hybridoma cells secreting anti-BVDV monoclonal antibodies (mAbs). Two hybridoma clones secreting mAbs, reacting
To understand mechanisms of viral diarrhea further, we studied ileal ion transport in vitro in relation to mucosal changes and epithelial differentiation in transmissible gastroenteritis in piglets, an invasive viral enteritis thought to involve mainly proximal intestine. In infected pigs, at the
Fifteen patients with advanced solid tumors participated in a phase I study of a biochemically designed combination chemotherapy program which employed PALA and thymidine (TdR) with 5-FU. PALA (250-2000 mg/m2) was given 24 hours before a 90-minute iv infusion of TdR (45 g). 5-FU (100-150 mg/m2) was
BACKGROUND
A phase II study was designed to evaluate the efficacy, safety and predictors for response of metronomic chemotherapy using weekly low-dosage CPT-11 and doxifluridine (5'-DFUR) in 45 patients with metastatic colorectal cancer.
METHODS
Forty mg/m2 of CPT-11 was administered for 3
High-dose thymidine (dThd) was given to 12 patients with advanced hematological and solid tumors. The dose schedule used was 75 g/sq m/day, given i.v. continuously for 5 days or more. Myelosuppression, especially leukopenia, was the dose-limiting toxicity. Nonhematological toxicities affected the
The physiological pyrimidine nucleoside thymidine (dThd) is cytotoxic to normal and neoplastic cells in culture that are exposed to concentrations in excess of 1 mM for prolonged periods. In order to explore the antileukemic potential of the compound, we have treated six patients with relapsed
A total of 15 patients with advanced neoplastic disease, 13 with different solid tumors, one with lymphoma, and one with acute lymphocytic leukemia, underwent treatment consisting of continuous infusion of methotrexate (2 g/sq m/day) with concomitant thymidine (8 g/sq m/day) and leucovorin (1 mg/sq
Enterohemorrhagic Escherichia coli (EHEC) are source of emerging infectious disease in India. Escherichia coli O157:H7 is an EHEC strain showing multiple antibiotic resistances and the cause of infantile diarrhea and hemolytic uremic syndrome worldwide. A novel strategy to counteract multiple
Our laboratory has previously demonstrated that 4-24-h thymidine exposures (50-1000 micrograms/ml) will enhance carboplatin cytotoxicity 2-3.3-fold in vitro. In order to show that these results are clinically applicable, we performed 24-h thymidine infusions with and without carboplatin in B6D2 F1
Functional interaction between lymphoid cells and lymphotropic viruses is particularly evident for bovine viral diarrhea virus (BVDV) in cattle and its closely related virus, the border disease virus (BVDV) in sheep. The most important aspect of acute or chronic phases of BVDV or BDV infection was
Neutrophil function and mononuclear cell proliferative responses to mitogens were determined in healthy cattle and in cattle persistently infected with bovine viral diarrhea (BVD) virus. Uptake of [3H]thymidine by resting and mitogen-stimulated peripheral blood mononuclear cells was significantly
The gene encoding the envelope protein (E2) of bovine viral diarrhea virus (BVDV) was expressed under the thymidine kinase (TK) promoter of Korean bovine herpesvirus 1 (BHV-1) isolate. Thymidine kinase negative (TK-) BHV-1 recombinants expressing E2 of BVDV were constructed and the expression of E2
We measured the response of jejunal sodium (Na) absorption to neutral amino acid (L-alanine) and to dipeptides (L-alanyl-L-alanine, glycylsarcosine) in normal piglets and in piglets with acute viral diarrhea after experimental infection with transmissible gastroenteritis (TGE) virus. In the TGE
