The mechanism of augmentation of tumor cell killing by immune effector cells and chemotherapeutic drugs was studied. The effect of treating tumor cells with various antineoplastic drugs on their sensitivity to murine natural cell-mediated cytotoxicity in vitro was investigated. Pretreatment with actinomycin D at nontoxic concentrations rendered L929 and WEHI-164 tumor cells more susceptible to ...

A novel aerobic, Gram-negative bacterium, named 13IX/A01/164(T), was isolated from surface waters in the coastal north-western Mediterranean Sea. Cells were motile, straight rods, 2.5 mum long and 0.2 mum wide, and formed orange colonies on marine agar medium. The G+C content of the genomic DNA of strain 13IX/A01/164(T) was 42 mol%. Phylogenetic analysis of the 16S rRNA gene sequence placed the...

The objective of the present study was to investigate vascular endothelial growth factor A (VEGFA) isoform regulation of cell fate decisions of spermatogonial stem cells (SSC) in vivo. The expression pattern and cell-specific distribution of VEGF isoforms, receptors, and coreceptors during testis development postnatal d 1-180 suggest a nonvascular function for VEGF regulation of early germ cell...

We evaluated a new membrane dot immunobinding assay (CMV-CUBE; Difco Laboratories) for the detection of cytomegalovirus (CMV) antibody in marrow transplant patients and donors. The CMV-CUBE assay was compared with a commercially available enzyme immunoassay (EIA; CMV STAT) and a latex agglutination (LA; CMVScan) test. Serum samples were collected from 311 transplant patients and donors prior to...
