Multiple sclerosis (MS) is a demyelinating neuro- inflammatory autoimmune disease of the central nervous system. Genetic predisposition has long been suspected in the etiology of this disease. The association between MTHFR polymorphisms and MS has been ivestigated in different ethnic groups. We investigated the association between MTHFR C677T and A1298C missense variants and MS in 180 patients ...

β-thalassemia is a syndrome characterized by a reduction or complete absence of the β-globin chain. More than 25 mutations within and flanking the β-globin gene have been identified as the cause of this syndrome in Thailand. To date, several PCRbased techniques have been employed to rapidly identify the types of β-thalassemia mutations. The recently introduced MS-PCR is among those techniques u...

Francisella tularensis is the cause of the zoonotic disease tularemia and is classified among highly pathogenic bacteria (HPB) due to its low infection dose and potential for airborne transmission. In the case of HBP, there is a pressing need for rapid, accurate and reliable identification. Phenotypic identification of Francisella species is inappropriate for clinical microbiology laboratories ...

Detection of Mycoplasma synoviae (MS) by culture and polymerase chain reaction (PCR) has been reported from commercial chicken farms in different provinces of Iran. In some reports the phylogenetic analysis of MS isolates based on 16S rRNA and variable lipoprotein hemagglutinin (vlhA) genes have been carried out. The PCR product containing partial 16S rRNA genes of Iranain isolates was sequence...

BACKGROUND PCR coupled with electrospray ionization mass spectrometry (ESI-MS) is a diagnostic approach that has demonstrated the capacity to detect pathogenic organisms from culture negative clinical samples after antibiotic treatment has been initiated. [1] We describe the application of PCR/ESI-MS for detection of bacteria in original patient specimens that were obtained after administration...

When tapping is paced by an auditory sequence containing small phase shift (PS) perturbations, the phase correction response (PCR) of the tap following a PS increases with the baseline interonset interval (IOI), leading eventually to overcorrection (B. H. Repp, 2008). Experiment 1 shows that this holds even for fixed-size PSs that become imperceptible as the IOI increases (here, from 400 to 120...

We describe the evaluation of culture-negative synovial fluid from a 3-year-old boy by PCR and electrospray ionization followed by mass spectrometry (PCR/ESI-MS). Our patient developed a diffuse rash and fever with systemic signs and symptoms of sepsis, but four sets of blood cultures obtained prior to initiation of antibiotics were negative. After 1 week of illness, he developed right-knee swe...

With increasing knowledge about the causal role of genetic defects in clinical diseases the necessity is apparent to have procedures for rapid diagnosis of point mutations. We developed a PCR-based technique, whereby both normal and mutant alleles can be amplified in the same reaction tube, using different length allele-specific primers. Furthermore the allele-specific primers introduce additio...
