RESUMEN
A Gram-stain-negative, rod-shaped and motile strain, designated PAMC 27536T, was isolated from deep-sea sediment in the East Sea, Korea. Analysis of the 16S rRNA gene sequence of the strain showed an affiliation with the genus Marinobacterium. Phylogenetic analyses revealed that strain PAMC 27536T was related most closely to Marinobacterium rhizophilum CL-YJ9T with a 16S rRNA gene sequence similarity of 98.5 % and to other members of the genus Marinobacterium (94.0-91.7 %). Genomic relatedness analyses between strain PAMC 27536T and M. rhizophilum KCCM 42386T gave an average nucleotide identity of 85.6 % and an estimated DNA-DNA hybridization of 24.6 % using the genome-to-genome distance calculator, indicating that they represent genomically distinct species. Cells of strain PAMC 27536T grew optimally at 25-30 °C and pH 7.0-7.5 in the presence of 3 % (w/v) sea salts. The major cellular fatty acids were C16 : 1ω6c and/or C16 : 1ω7c, C18 : 1ω6c and/or C18 : 1ω7c, and C16 : 0. The major isoprenoid quinone was Q-8. The genomic DNA G+C content was 56.1-57.2âmol%. Based on the phylogenetic, chemotaxonomic, genomic and phenotypic data presented, a novel species with the name Marinobacterium profundum sp. nov. is proposed, with PAMC 27536T ( = KCCM 43095T = JCM 30410T) as the type strain.
RESUMEN
We investigated the association between the use of inhaled bronchodilators and the risk of AMI. A nested case-control study using the nationwide insurance claims database was conducted. Overall, 11,054 AMI cases and 47,815 matched (up to 1:5) controls were identified from 1,036,119 subjects without acute major cardiovascular events in the past year. Long-acting and short-acting ß-agonists (LABAs and SABAs) were associated with increase in the risk of AMI, although an inhaled corticosteroid combined with a long-acting ß-agonist was not. Long-acting muscarinic antagonists (LAMAs) in a dry powder inhaler (DPI) were significantly associated with reduced risk of AMI, while LAMAs in a soft mist inhaler (SMI) didn't decrease the risk of it. In hypertensive or diabetic patients, LAMAs in a DPI were associated with reduced risk of AMI, but LABAs were associated with increased risk. Among the ß-blocker users, the reduction of AMI risk by LAMAs was the most significant. In conclusions, inhaled ß-agonists were associated with increase in the risk of AMI, while LABAs accompanied by ICSs were not associated with increase in the risk of AMI. LAMAs in a DPI use were associated with lower risk of AMI.
