Background and purpose: Recent studies suggest that the viable but nonculturable (VBNC) bacteria could cause inflammatory diseases. The aim of this study was to detect and investigate the expression of nuc and rfbE genes in blood samples of patients with rheumatoid arthritis (RA). Materials and methods: In this experimental study, 102 blood samples were collected from patients with RA and univ...
Background: Early diagnosis of bacteremia and its complications is the most important part of care and management of the patients. The utility of polymerase chain reaction (PCR) techniques have been shown to identify pathogens in less and more optimal time. The aim of our study was to evaluate prevalence of bacteremia using universal PCR in febrile patients admitted in Pediatric Medical Center ...
chapter two presents three m-admissible function algebras ab, bd, and sl, to construct the universal abelian, band, and semilattice compactifications, respectively. the main results are (11.3), (12.3), and (12.4). some inclusion relationships between these function algebras and the other well-known ones, presented in section 8, are made via the devico of compactifications. chpter three is about...
A small-oligonucleotide microarray prototype was designed with probes specific for the universal 16S rRNA and cpn60 genes of several pathogens that are usually encountered in wastewaters. In addition to these two targets, wecE-specific oligonucleotide probes were included in the microarray to enhance its discriminating power within the Enterobacteriaceae family. Universal PCR primers were used ...
Polymerase chain reaction (PCR) as a method for preparing DNA templates has been used for several DNA sequencing applications. An in situ procedure for directly sequencing PCR products by the dideoxy-termination method has been developed by using fluorophore-labeled sequencing primers. Completed sequence reactions were combined and loaded into a single electrophoretic lane of a fluorescence-bas...
BACKGROUND Screening at hospital admission for carriage of methicillin-resistant Staphylococcus aureus (MRSA) has been proposed as a strategy to reduce nosocomial infections. The objective of this study was to determine the long-term costs and health benefits of selective and universal screening for MRSA at hospital admission, using both PCR-based and chromogenic media-based tests in various se...
BACKGROUND With the invention of the DNA chip, genome-wide analysis is now a reality. Unfortunately, solid-phase detection systems such as the DNA chip suffer from a narrow range in quantification and sensitivity. Today the best methodology for sensitive, wide dynamic range quantification and genotyping of nucleic acids is real-time PCR. However, multiplexed real-time PCR technologies require c...
Free-living nitrogen-fixing prokaryotes (diazotrophs) are ubiquitous in soil and are phylogenetically and physiologically highly diverse. Molecular methods based on universal PCR detection of the nifH marker gene have been successfully applied to describe diazotroph populations in the environment. However, the use of highly degenerate primers and low-stringency amplification conditions render t...
Conventional genomic DNA extraction protocols need expensive and hazardous reagents for decontamination of phenolic compounds from the extracts and are only suited for certain types of tissue. We developed a simple, time-saving and cost-efficient method for genomic DNA extraction from various types of organisms, using relatively innocuous reagents. The protocol employs a single purification ste...
Several site-directed mutagenesis methods have been developed and are being currently used in research. All these methods apply three or four primers, including one or two bearing the appropriate mutation, and most use PCR to amplify the desired sequence and to incorporate the mutation (1–6). Although several developments have improved the robustness and reliability of the method, all of them r...
