The MICs of GW 773546, GW 708408, and telithromycin for 164 macrolide-susceptible and 161 macrolide-resistant pneumococci were low. The MICs of GW 773546, GW 708408, and telithromycin for macrolide-resistant strains were similar, irrespective of the resistance genotypes of the strains. Clindamycin was active against all macrolide-resistant strains except those with erm(B) and one strain with a ...
A total of 322 erythromycin-resistant pneumococci from TRUST 3 and TRUST 4 United States surveillance studies (1999-2000) were screened for 23S rRNA, L4, and L22 gene mutations. Nineteen isolates, two with mefA, had mutations at position 2058 or 2059 in 23S rRNA. Two had a 69GTG71-to-TPS substitution in L4; one of these also contained ermA.
اهمیت روزافزون بهره¬وری باعث شده است که این مقوله از مسایل مهم مورد بحث و مطالعه در ادبیات نظری و تجربی سازمان¬دهی صنعتی شود. از سویی دیگر، متون اصیل اقتصادی بر نقش ساختار بازارها در تحولات بهره-وری تأکید و اختلاف دارند. در حالی که برخی از نظریه پردازان به گسترش رقابت در بازار محصول به منظور افزایش بهره¬وری و کارآیی اشاره می¬کنند، عده¬ای دیگر محیط انحصاری را برای این امر مناسب می دانند. این د...
Custodians play a key but discrete role in the global financial market infrastructure. In Europe, they are licensed as “credit institutions ”, legal requirement for European deposit-taking institutions, and therefore face same prudential requirements “traditional” banks. However, their business model risk profile different from those of traditional banks since core activity does not encompass b...
Resistance to quinupristin-dalfopristin (Q/D) among gram-positive cocci has been very uncommon. Two clinical isolates among 8,837 (0.02%) Streptococcus pneumoniae isolates were discovered in 2001 to 2002 with Q/D MICs of 4 micro g/ml. Each had a 5-amino-acid tandem duplication (RTAHI) in the L22 ribosomal protein gene (rplV) preventing synergistic ribosomal binding of the streptogramin combinat...
The resistance patterns and macrolide resistance mechanisms of 910 Finnish invasive pneumococci isolated during 1999 and 2000 were studied. Macrolide resistance was detected in 6.9% of isolates. Penicillin resistance was detected in 1.5% of isolates, and penicillin intermediate resistance was detected in 4.0% of isolates. Active macrolide efflux, mediated by the mef(A) gene, was the most common...
We discuss the l2-lp (with p ∈ (0, 1)) matrix minimization for recovering low rank matrix. A smoothing approach is developed for solving this non-smooth, non-Lipschitz and non-convex optimization problem, in which the smoothing parameter is used as a variable and a majorization method is adopted to solve the smoothing problem. The convergence theorem shows that any accumulation point of the seq...
We develop a model to study the implications of a legal environment on the organization of software production. We show that contract enforcement a®ects the organizational mode (i.e., in-house versus outsourcing) of customized software development while copyright protection determines the introduction of package software. When copyright protection is weak, only customized software will be devel...
