The Friend viruses, like the Rauscher virus, cause murine acute erythroleukemias which evolve in a similar multistep process. In previous studies it has been described that the late malignant proerythroblastic transformation induced by the polycythemia-inducing strain of Friend spleen focus-forming virus (SFFVP) is correlated with Spi-1 oncogene activation(More)
The Working Party on Antibiotic Policy (Dutch acronym is SWAB) is a Dutch organisation that develops guidelines for in-hospital antimicrobial therapy of bacterial infectious diseases. This present guideline describes the antimicrobial treatment for adult patients with infective endocarditis. The choice and duration of antimicrobial therapy is determined by(More)
In mice the majority of the immunoglobulins (Ig) in milk belongs to the IgA class. Prior to its transepithelial transportation into the milk, dimeric IgA (dIgA) is bound to the transmembrane form of the secretory component or polymeric Ig receptor (SC/pIgR). The latter is synthesized in the epithelial cells lining the ducts and alveoli of the mammary gland.(More)
At present non-invasive tests for diagnosing Schistosoma myelopathy are sub-optimal. We present a novel serological method, using paired liquor and serum samples, resulting in the diagnosis of Schistosoma myelopathy in a male patient with proximal muscle weakness. The patient recovered after praziquantel treatment.
Dog peripheral blood lymphocytes, when cultured with 35S-methionine in the presence of tunicamycin, synthesize DLA molecules consisting of beta 2-microglobulin and a heavy chain approximately 3000 daltons lower in apparent mol. wt. than observed in control cases. This difference in mol. wt. is consistent with the fact that a single N-linked carbohydrate(More)
After transfection of NIH 3T3 cells with DNA from molecularly cloned Rauscher MuLV, virus was isolated which showed a disease spectrum comparable to that of R-MuLV cloned biologically by endpoint dilution. In both cases sites of proviral integration vary from 2-5 per leukemic tissue and occur apparently at random.
A comparative study on the expression of nuclear and cytoplasmic oncogenes was carried out using the Northern blotting technique, in Rauscher virus induced primary leukemias and the more malignant transformed cell lines derived from them. The latter grow permanently in vitro. Hyperplastic spleens obtained from mice recovering from anemia were analysed as(More)
The objective of the study was to evaluate a rapid screening technique for the presence of mutations in the viral reverse transcriptase gene of HIV following prolonged therapy with zidovudine in patients with AIDS. Peripheral blood mononuclear cells (PBMCs) of 14 HIV-infected patients were analyzed by micro-titer point mutation assay (PMA) before therapy(More)
Atevirdine mesylate (U-87201E) is a new nonnucleoside (bisheteroarylpiperazine) inhibitor of human immunodeficiency virus type 1 reverse transcriptase. In a double-blind, escalating single-dose study the safety, tolerance, and pharmacokinetics of atevirdine mesylate were investigated in 24 asymptomatic human immunodeficiency virus-seropositive male(More)
Detergent-solubilized DLA class I antigens have been isolated by immunoprecipitation from peripheral blood lymphocytes with an anti-beta 2-microglobulin serum and an alloantiserum. Amino acid composition and NH2-terminal amino acid sequence analysis confirmed that the DLA light chain is identical to dog urinary beta 2-microglobulin, and that the DLA heavy(More)
