Molecular typing of Klebsiella species has become important for monitoring dissemination of β-lactamase-producers in hospital environments. The present study was designed to evaluate poly-trinucleotide (GTG)(5)- and rDNA intergenic transcribed spacer (ITS)-PCR fingerprint analysis for typing of Klebsiella pneumoniae and Klebsiella oxytoca isolates. Multiple displacement amplified DNA derived fr...

I The phyto-estrogens formononet in (7-hydroxy-4 methoxylsoflavone) and biochanin A (5-7-dlhydroxy-4-methoxylsof lavone) were independently incubated in vitro at 39~ in bovine rumen fluid from a fistulated steer receiving an alfalfa hay diet. Formononet in was incubated in studies 1 and 2, whereas biochanin A was incubated in s tudy 3. The isoflavones were separated and quantified by high perfo...

CcaR is a positive-acting transcriptional regulator involved in cephamycin C and clavulanic acid biosynthesis in Streptomyces clavuligerus. Previous sequence analyses of the ccaR gene revealed two possible start codons, an ATG, and a GTG located in-frame 18 bp downstream of the ATG. To determine the true start codon, ccaR was expressed, either from the GTG or ATG codon, in Escherichia coli. A p...

AIM To evaluate the role of whole genome comparative genomic hybridisation microarray (array-CGH) in detecting genomic imbalances as compared to conventional karyotype (GTG-analysis) or myeloma specific fluorescence in situ hybridisation (FISH) panel in a diagnostic setting for plasma cell dyscrasia (PCD). METHODS A myeloma-specific interphase FISH (i-FISH) panel was carried out on CD138 PC-e...

Five repetitive-element PCR (rep-PCR) techniques [primer sets ERIC1R-ERIC2 and REP1R-REP2I and primers ERIC2, BOXA1R, and (GTG)5] were evaluated for the discrimination of Salmonella enterica isolates at the serotype level. On the basis of number, even distribution over the whole fingerprint, and clarity of bands in the fingerprints, the enterobacterial repetitive intergenic consensus (ERIC) pri...

OBJECTIVE To evaluate the effect of the consumption of green tea on components of MS in the elderly. DESIGN Intervention study. SETTING The sample was selected from the Geriatric Service of Hospital São Lucas of Pontifical Catholic University of Rio Grande do Sul. PARTICIPANTS 45 elderly with MS were enrolled and allocated into two groups: green tea group (GTG, n= 24), who drank green tea...

In this paper we propose new three-input XOR and three-input XNOR gate based on generalized threshold gate (GTG) topology. The GTG topology is main part is monostable-bistable logic element (MOBILE). The proposed gates use fewer elements count in comparison with other implementations which utilize MOBILE as a main structure. By exploiting the new three-input XOR gate and a carry generator, we p...

A set of reference strains and a group of previously unidentified enterococci were analysed by rep-PCR with the (GTG)(5) primer to evaluate the discriminatory power and suitability of this method for typing and identification of enterococcal species. A total of 49 strains representing all validly described species were obtained from bacterial collections. For more extensive evaluation of this i...

Beef and its products are potential vehicles of Escherichia coli O157, the most important serotype implicated in many large outbreaks of diarrheal infection in humans worldwide. There is a need for rapid detection of contaminated food in order to implement appropriate and effective control measures. In this study, repetitive sequence (rep)-PCR, using three different primers, BOXA1R, ERIC2 and (...
