background and objectives: pseudomonas aeruginosa is one of the most important opportunistic pathogens in patients who suffer from immunodeficiency and burns. wound infections caused by p. aeruginosa can rapidly change to systemic and life threatening situation. the aim of this study was to apply florescent in situ hybridization (fish) method for rapid detection of p. aeruginosa in burrn patien...

background and purpose: salmonella is a group of enterobacterias that cause infectious diseases in human and animals. typhoid, bacteremia, enterocolitis and salmonellosis which are caused by this bacterium are considered major health concerns in developing countries, such as iran. quick, accurate, reliable and early diagnosis is vital to prevent salmonella outbreak. materials and methods: there...

we investigated the use of dna amplification by polymerase chain reaction (per) for detection of mycobacterium tuberculosis in 300 patients who were suspected of having pulmonary tuberculosis and compared the results with culture results which were performed in parallel with pcr. two-thirds of each sample was processed for smear and culture by standard methods and one-third was prepared for dna...

background: the ultrasonography probes are cleaned by absorbent soft, dry cloth. this question arose whether linear and convex ultrasound probes coupling with gel could perform as a means for nosocomial infections transmission, and which method is economical and more efficient for cleaning the probes. this study was conducted to answer these questions. methods: one hundred – ninety two patients...

Links in many real-world networks activate and deactivate in correspondence to the sporadic interactions between the elements of the system. The activation patterns may be irregular or bursty and play an important role on the dynamics of processes taking place in the network. Information or disease spreading in networks are paradigmatic examples of this situation. Besides burstiness, several co...

Most current microarray oligonucleotide probe design strategies are based on probe design factors (PDFs), which include probe hybridization free energy (PHFE), probe minimum folding energy (PMFE), dimer score, hairpin score, homology score and complexity score. The impact of these PDFs on probe performance was evaluated using four sets of microarray comparative genome hybridization (aCGH) data,...

Single molecule fluorescence measurements have recently been used to probe the orientation of fluorescent lipid analogs doped into lipid films at trace levels. Using defocused polarized total internal reflection fluorescence microscopy (PTIRF-M), these studies have shown that fluorophore orientation responds to changes in membrane surface pressure and composition, providing a molecular level ma...

The XML-based Clinical Document Architecture (CDA) for document exchange defines a three-level document architecture with each higher level adding more specificity to the markup of the document. Such a layered architecture also meets the requirement for semantic processing of hierarchically structured clinical documents. The CDA supports shared care between hospital-based and community-based ph...
