14. Evaluation of New Quantitative Assays for Diagnosis and Monitoring of Cytomegalovirus Disease in Human Immunodeficiency Virus-Positive Patients
Cobas Amplicor CMV Monitor (CMM) and Quantiplex CMV bDNA 2.0 (CMV bDNA 2.0), two new standardized and quantitative assays for the detection of cytomegalovirus (CMV) DNA in plasma and peripheral blood leukocytes (PBLs), respectively, were compared to the CMV viremia assay, pp65 antigenemia assay, and the Amplicor CMV test (P-AMP). The CMV loads were measured

15. Cleavage of adenosine 5'-monophosphate during uptake by Streptomyces griseus.
Unlabeled adenine brought about a (delayed) decrease in radioactivity that had been taken up by phosphate-limited resting cells of Streptomyces griseus from [14C]adenine-labeled adenosine 5'-monophosphate (AMP). Inorganic phosphate, on the other hand, stimulated adenine uptake from AMP, presumably by activating an energy-dependent active transport mechanism.

16. Prevalence of the Genes Encoding Propionicin T1 and Protease-Activated Antimicrobial Peptide and Their Expression in Classical Propionibacteria
The purpose of this study was to investigate the frequency of production of the bacteriocin propionicin T1 and the protease-activated antimicrobial peptide (PAMP) and their corresponding genes in 64 isolates of classical propionibacteria. This study revealed that these genes are widespread in Propionibacterium jensenii and Propionibacterium thoenii but absen

17. Photoaffinity labeling of cyclic-AMP- and AMP-binding proteins differentiating Dictyostelium discoideum cells.
Cyclic-AMP-binding proteins play important roles during the differentiation of the cellular slime mold Dictyostelium discoideum. The photoaffinity reagent 8-N3-cyclic [32P]AMP has been used to label developmentally regulated cyclic-AMP-binding proteins of intact cells, membranes, and cytoplasm. 8-N3-Cyclic AMP is a chemoattractant for differentiated D. disco

18. Use of Laboratory Assays To Predict Cytomegalovirus Disease in Renal Transplant Recipients
Eight laboratory assays, viz., the pp65 direct antigenemia test, a quantitative cytomegalovirus (CMV)-specific immunoglobulin G (IgG) assay (Biomerieux VIDAS), a CMV-specific IgM assay (Biomerieux VIDAS), the Hybrid Capture system (Murex), an in-house PCR with plasma (P-PCR) and leukocytes (L-PCR), and a commercial PCR (Roche AMPLICOR) with plasma (P-AMP) an

19. CCL20/Macrophage Inflammatory Protein 3α and Tumor Necrosis Factor Alpha Production by Primary Uterine Epithelial Cells in Response to Treatment with Lipopolysaccharide or Pam3Cys
Having previously shown that CCL20/macrophage inflammatory protein 3α and tumor necrosis factor alpha (TNF-α) are released by polarized primary rat uterine epithelial cells (UEC) in response to Escherichia coli but not to Lactobacillus rhamnosus, we sought to determine if epithelial cells are responsive to pathogen-associated molecular patterns (PAMP), inc

20. The N Terminus of Bacterial Elongation Factor Tu Elicits Innate Immunity in Arabidopsis Plants
Innate immunity is based on the recognition of pathogen-associated molecular patterns (PAMPs). Here, we show that elongation factor Tu (EF-Tu), the most abundant bacterial protein, acts as a PAMP in Arabidopsis thaliana and other Brassicaceae. EF-Tu is highly conserved in all bacteria and is known to be N-acetylated in Escherichia coli. Arabidopsis plants sp

21. Synthesis of complementary RNA containing polyadenylic acid by Sendai virions in vitro.
Sendai virus synthesized, in vitro, [32P]AMP- and [3H]AMP-labeled RNA that ranged in size from 3 to 25S with major peaks at 7S and 13S. Both labeled products were predominantly single-stranded RNA and were complementary in base sequence to 50S virion RNA. Passage of the 3 to 25S in vitro RNA transcripts through a polyuridylic acid-cellulose column revealed t

22. Inorganic polyphosphate in the social life of Myxococcus xanthus: Motility, development, and predation
Inorganic polyphosphate (poly P), a polymer of tens or hundreds of phosphate residues linked by high-energy, ATP-like bonds, is found in all organisms and performs a wide variety of functions. Myxococcus xanthus, a social bacterium that feeds on other bacteria and forms fruiting bodies and spores, depends on poly P for motility, development, and nutritional

23. Inhibitory Effect of a Rhizobitoxine Analog on Bud Growth after Release from Dormancy
Application of the ethoxy analog of rhizobitoxine (l-2-amino-4-[2′-aminoethoxy]-trans-3-butenoic acid), an inhibitor of ethylene biosynthesis, inhibited growth of apple, crabapple, and apricot buds released from dormancy by chilling or by treatment with benzyladenine. When tea crabapple (Malus hupehensis [Pamp.] Rehd.) buds were sprayed once with 8.8 × 10

24. Identification of a specific inhibitor for DNA ligase I in human cells.
A protein inhibitor for human DNA ligase I has recently been identified. It was copurified with a fraction of the enzymes from HeLa cells through several steps of chromatography. The inhibitor was first identified by the absence of ligation activity of the associated enzyme, while it retained the ability to form the ligase-[32P]AMP adducts. The inhibitor was
