The fla/che region contains more than 30 genes required for flagellar synthesis and chemotaxis in Bacillus subtilis, including the gene for the flagellum-specific sigmaD factor, sigD. Sequence and primer extension data demonstrate that a PA promoter immediately upstream of flgB, henceforth referred to as the fla/che PA, and the PD-3 promoter are active in vivo. Transcription from the PD-3 eleme...

The role of motility as a virulence factor in Pseudomonas aeruginosa burn wound sepsis was examined using mutants deficient in the Fla or Mot phenotype. Physiological profiles of parental strains and Fla- and Mot- mutants were similar with respect to antibiograms, O antigen types, growth rates, and proteolytic, exotoxin A and phospholipase activities, providing evidence for isogenicity. Lethali...

Little attention has been given to the involvement in formal learning activities (FLA) in the older population when considering different health statuses. The aim of this study is to explore the extent to which possible predictors (derived from previous research as well as a conceptual model) of FLA differ for older people in poor and good health. Data are used from SHARE 2010/2011 for the 50+ ...

The effects of two dopamine-beta-hydroxylase (DBH) inhibitors, FLA-63 and fusaric acid (FA) on feeding behaviour and locomotor activity were examined. In Experiment 1 activity was measured over 7 hr in 48 rats treated with FLA-63 (0, 1.25, 2.50, 5.00 mg/kg) or FA (0, 20.0, 40.0, 80.0 mg/kg). While FA produced no significant effect on activity, FLA-63 produced an increase at the highest doses. I...

Huanglongbing (HLB) is presently the most devastating citrus disease worldwide. As an intracellular plant pathogen and insect symbiont, the HLB bacterium, 'Candidatus Liberibacter asiaticus' (Las), retains the entire flagellum-encoding gene cluster in its significantly reduced genome. Las encodes a flagellin and hook-associated protein (Fla) of 452 amino acids that contains a conserved 22 amino...

The present work focuses on a local survey of free-living amoebae (FLA) that cause opportunistic and nonopportunistic infections in humans. Determining the prevalence of FLA in water sources can shine a light on the need to prevent FLA related illnesses. A total of 150 samples of tap water were collected from six districts of Sivas province. The samples were filtered and seeded on nonnutrient a...

Comparisons of the genomic structure of 3 mammalian major histocompatibility complexes (MHCs), human HLA, canine DLA, and feline FLA revealed remarkable structural differences between HLA and the other 2 MHCs. The 4.6-Mb HLA sequence was compared with the 3.9-Mb DLA sequence from 2 supercontigs generated by 7x whole-genome shotgun assembly and 3.3-Mb FLA draft sequence. For FLA, we confirm that...

We assessed the safety and efficacy of reconstructive therapy with facial fillers for the treatment of HIV-associated facial lipoatrophy (FLA) through a randomized, controlled, open-label single-center study. A total of 134 HIV-infected patients with severe FLA were randomly assigned to receive immediate (67 patients) or delayed (67 patients) facial injections of poly-l-lactic acid (PLA) or pol...

A survey was carried out from August to December 2004 in Pusan, Korea to document the presence of free-living amoeba (FLA), including the genus Acanthamoeba, in both contact lens storage cases and domestic tap water. Acanthamoeba was isolated from 5 (4.2%) in 120 contact lens storage cases. Four house tap water samples from residents, whose contact lens storage cases had been contaminated by Ac...
