Multiple roles of the pilus biogenesis protein pilD: involvement of pilD in excretion of enzymes from Pseudomonas aeruginosa.

Author(s) : Strom, M S , Nunn, D , Lory, S
Description : In Pseudomonas aeruginosa, the genes pilB, pilC, and pilD encode proteins necessary for posttranslational modification and assembly of pilin monomers into pilus organelles (D. Nunn, S. Bergman, and S. Lory, J. Bacteriol. 172:2911-2919, 1990). We show that PilD, encoding a putative pilin-specific lea...

Cloning and characterization of a gene (fadR) involved in regulation of fatty acid metabolism in Escherichia coli.

Author(s) : DiRusso, C C , Nunn, W D
Description : The regulatory gene fadR has been previously characterized by classical genetic means as a diffusible protein which exerts negative control over fatty acid degradation and acetate metabolism. fadR has also been implicated in the regulation of unsaturated fatty acid biosynthesis. To facilitate the id...

Interaction of Pseudomonas aeruginosa with A549 pneumocyte cells.

Author(s) : Chi, E , Mehl, T , Nunn, D , Lory, S
Description : The interaction of Pseudomonas aeruginosa with a human lung pneumocyte cell line (A549) was studied. Wild-type strain PAK adhered efficiently to the A549 cells, while an isogenic mutant, carrying a mutation in the pilin structural gene, adhered at 10 to 20% of the wild-type levels. Another nonpiliat...

Elevated levels of glyoxylate shunt enzymes in Escherichia coli strains constitutive for fatty acid degradation.

Author(s) : Maloy, S R , Bohlander, M , Nunn, W D
Description : Mutants of Escherichia coli K-12 constitutive for the synthesis of the enzymes of fatty acid degradation (fadR) have elevated levels of the glyoxylate shunt enzymes, isocitrate lyase and malate synthase. A temperature-sensitive fadR strain has high levels of glyoxylate shunt enzymes when grown at el...

Prolactin and seizure activity.

Author(s) : Bye, A M , Nunn, K P , Wilson, J
Description : Prolactin secretion after tonic-clonic seizures (10 patients), complex partial seizures (five) and non-epileptic attacks (three) was studied in a group of children aged between 0.3 and 14 years. Seven patients with other subcategories of seizure disorders were also studied. Eight children with tonic...

Commentary: making tuberculosis treatment available for all.

Author(s) : Maher, D. , Nunn, P.
Description : Tuberculosis is one of the major public health problems that WHO has tackled throughout the last 50 years. During the pre-clinical era treatment consisted of the use of special diets, bed rest in sanatoria, and lung collapse therapy. The case fatality rate 5 years after diagnosis was 50% and treatme...

Evaluation and determinants of outcome of tuberculosis treatment.

Author(s) : Maher, D. , Nunn, P.
Description : The most important determinant of the outcome of treatment of tuberculosis (TB) patients is the access that they have to reliable diagnosis and treatment services organized within a national tuberculosis programme (NTP) as part of DOTS, the name of the WHO-recommended TB control strategy. Accurate e...

Network-based diffusion analysis: a new method for detecting social learning

Author(s) : Franz, Mathias , Nunn, Charles L.
Description : Social learning has been documented in a wide diversity of animals. In free-living animals, however, it has been difficult to discern whether animals learn socially by observing other group members or asocially by acquiring a new behaviour independently. We addressed this challenge by developing net...

Peak expiratory flow in symptomless elderly smokers and ex-smokers.

Author(s) : Gregg, I. , Nunn, A. J.
Description : Values of peak expiratory flow (PEF) in 142 current smokers (116 men, 26 women) and 108 ex-smokers (88 men, 20 women) aged 55 or over were compared with the predicted values obtained in lifelong nonsmokers of the same age range. None of the subjects had been liable during childhood or subsequently t...
