These pathogens are important causes of hospital-and community-associated infections in children.
Methods: PubMed was searched for all English language articles on patients younger than 18 years of age treated with linezolid, and an analysis of these articles was performed.
Results: From the 133 articles retrieved, a total of 30 were studied (18 case reports, nine case series, and three clinical trials) based on the inclusion criteria preset for this review. In these articles, a total of 597 children received linezolid. MRSA was the most common pathogen, followed by VRE, PRSP, other bacteria and less common mycobacterial species. Linezolid was reported to be safe and effective for the treatment of
pneumonia and endocarditis, SNS-032 solubility dmso as well as skin and soft tissue, central nervous system and osteoarticular infections.
Conclusions: Linezolid is promising as a safe and efficacious agent for the treatment of infections due to mainly resistant Gram-positive
organisms in children who are unable to tolerate conventional agents or after treatment failure. (C) 2010 International Society for Infectious Diseases. Published by Elsevier Ltd. All rights reserved.”
“Large macromolecular assemblies are often important for biological processes in cells. Allosteric communications between different parts of these molecular machines play critical roles in cellular signaling. Although studies of the topology and fluctuation BMS-345541 research buy dynamics
of coarse-grained Smad phosphorylation residue networks can yield important insights, they do not provide characterization of the time-dependent dynamic behavior of these macromolecular assemblies. Here we develop a novel approach called Perturbation-based Markovian Transmission (PMT) model to study globally the dynamic responses of the macromolecular assemblies. By monitoring simultaneous responses of all residues (>8,000) across many (>6) decades of time spanning from the initial perturbation until reaching equilibrium using a Krylov subspace projection method, we show that this approach can yield rich information. With criteria based on quantitative measurements of relaxation half-time, flow amplitude change, and oscillation dynamics, this approach can identify pivot residues that are important for macromolecular movement, messenger residues that are key to signal mediating, and anchor residues important for binding interactions. Based on a detailed analysis of the GroEL-GroES chaperone system, we found that our predictions have an accuracy of 71-84% judged by independent experimental studies reported in the literature. This approach is general and can be applied to other large macromolecular machineries such as the virus capsid and ribosomal complex.”
