Bone cements produced by different manufacturers vary in their mechanical properties and antibiotic elution characteristics. Small changes in the formulation of a bone cement, which may not be apparent to surgeons, can also affect these properties. The supplier of Palacos bone cement with added gentamicin changed in 2005. We carried out a study to examine the mechanical characteristics and anti...
The properties of cefazolin, cefoxitin, cefamandole, and cefuroxime have been compared with those of cephaloridine, cephalothin, and cephalexin. The properties included for examination are the susceptibility to a range of beta-lactamases commonly encountered in gram-negative species and the ability of a beta-lactam antibiotic to penetrate the outer layers of Escherichia coli. Of the antibiotics...
let h be a separable hilbert space and let b be the set of bessel sequences in h. by using several interesting results in operator theory we study some topological properties of frames and riesz bases by constructing a banach space structure on b. the convergence of a sequence of elements in b is de_ned and we determine whether important properties of the sequence is preserved under the con...
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
Background and Objectives: Pseudomonas aeruginosa isolates from the lungs of cystic fibrosis (CF) patients are often heterogeneous and antibiotic resistant strains. Our work therefore focused on the antibiotic resistance properties of these P. aeruginosa strains isolated from Iranian patients, as well as the genetic diversity analysis by a repetitive-element-based molecular assay. Methods: This ...
Antibiotic resistance can be reduced by using antibiotics prudently based on guidelines of antimicrobial stewardship programs (ASPs) and various data such as pharmacokinetic (PK) and pharmacodynamic (PD) properties of antibiotics, diagnostic testing, antimicrobial susceptibility testing (AST), clinical response, and effects on the microbiota, as well as by new antibiotic developments. The contr...
Use of antibiotic-loaded bone cement for prophylaxis against infection is not indicated for patients not at high risk for infection who are undergoing routine primary or revision joint replacement with cement. The mechanical and elution properties of commercially available premixed antibiotic-loaded bone-cement products are superior to those of hand-mixed preparations. Use of commercially avail...
background although effective strategies have been presented for preventing the spread of antibiotic resistance in iran, recent reports have revealed increasing antibiotic resistance among children and adults. objectives in the present study, we tried to provide a clear view of the antibiotic resistance status of aerobic organism as the most prevalent organism in patients with rhinosinusitis in...
Prevalence and Antibiotic Resistance Pattern of Staphylococcus Aureus Strains Isolated from Food Stuff Soltan Dallal MM1, Agha Amiri S2, Eshraghian MR3, Sabour Yaraghi AA4, Faramarzi T5, Mahdavi V6, Saberpour F7, Fazeli Fard P7, Peymaneh Abedi Mohtasab TP1 1 Dev of Microbiology, Dept of Pathobiology, School of Public Health and Institute of Public Health Research, Tehran University of Medical S...
medical compounds, especially antibiotics, in which remains in milk and dairy products on the one hand causes health problems such as allergic reactions and Development of bacterial resistance to antibiotics are a serious threat to the health of consumers , and on the other hand, industrial troubles such as failure to produce fermented products can cause the milk back to the rancher. The purpos...
