A one-step simple synthesis of silver colloid nanoparticles with controllable sizes is presented. In this synthesis, reduction of [Ag(NH(3))(2)](+) complex cation by four saccharides was performed. Four saccharides were used: two monosaccharides (glucose and galactose) and two disaccharides (maltose and lactose). The syntheses performed at various ammonia(More)
The antifungal activity of the silver nanoparticles (NPs) prepared by the modified Tollens process was evaluated for pathogenic Candida spp. by means of the determination of the minimum inhibitory concentration (MIC), minimum fungicidal concentration (MFC), and the time-dependency of yeasts growth inhibition. Simultaneously the cytotoxicity of the silver(More)
A high power superconductive magnetostatic system MAGNEX was used by the authors for two microbial strains Escherichia Coli and Staphylococcus Aureus, the magnetic induction values were 0.5-4 T and the exposure time was 30-120 minutes. In this paper morphological traits, standard biochemical tests, sensitivity and effects influence of some chosen sorts of(More)
This prospective study compared PCR and culture techniques in the diagnosis of prosthetic joint infection (PJI). We obtained joint fluid samples (JFS; n=115) from patients who had failed total joint arthroplasty between January 2003 and June 2005; 49 were positive for PJI according to established strict criteria. JFS were analyzed by PCR (n=35; control(More)
PURPOSE OF THE STUDY Ten years after inauguration of the molecular methods into the orthopaedic practice for diagnosing Prosthetic Joint Infection (PJI), this approach is still in the limelight of research and discussion. The aim of the current study was to determine the diagnostic power of our Polymerase Chain Reaction (PCR) protocol for preoperative(More)
The growing interest in the composition and effects of microbiota raised the question how drug pharmacokinetics could be influenced by concomitant application of probiotics. The aim of this study was to find whether probiotic E. coli strain Nissle 1917 (EcN) influences the pharmacokinetics of concomitantly taken antiarrhythmic drug amiodarone (AMI). Live(More)
A rather fast and complicated progression of an infection caused by some strains of Staphylococcus aureus could be associated with the expression and co-action of virulence factor complexes in these strains. This study screened the antibiotic susceptibility and prevalence of virulence markers in isolates of meticillin-resistant S. aureus (MRSA) obtained(More)
This study assessed the effect of an 8 week consumption of dried cranberry juice (DCJ) on 65 healthy young women. Basic biochemical and hematological parameters, antioxidant status, presence of metabolites in urine, and urine ex vivo antiadherence activity were determined throughout the trial. A 400 mg amount of DCJ/day had no influence on any parameter(More)
Strains of the Burkholderia cepacia complex (Bcc) are opportunistic pathogens capable of causing serious infection in cystic fibrosis patients. Recently we identified a suspected outbreak of infection with Bcc strains at the University Hospital Olomouc. Seventy-four Bcc strains were isolated from 52 patients, most of whom (N = 48) did not suffer from cystic(More)
The organic fraction (OF; 25.7% w/w of rosmarinic acid) of Prunella vulgaris (total extract) was found to exhibit the following: scavenging activity on diphenylpicrylhydrazyl radical (DPPH), inhibition of in vitro human LDL Cu(II)-mediated oxidation, protection of rat mitochondria and rat hepatocytes exposed to either tert-butyl hydroperoxide, or to Cu(II)(More)
