The identification of translation initiation sites (TISs) constitutes an important aspect of sequence-based genome analysis. An erroneous TIS annotation can impair the identification of regulatory elements and N-terminal signal peptides, and also may flaw the determination of descent, for any particular …

Purpose With current diagnostic methods, the majority of patients with symptomatic colorectal anastomotic leakage (CAL) is identified approximately 1 week after operation. The aim of this study is to determine whether real-time polymerase chain reaction (RT-PCR) for detection of Escherichia coli and …

Common cloning is often associated with instability of certain classes of DNA. Here we report on IS1 transposition as possible source of such instability. During the cloning of Arabidopsis thaliana gene into commercially available vector maintained in widely used Escherichia coli host the insertion of …

tIn this study we aimed to identify genes that are responsive to pertussis toxin (PTx) and might eventu-ally be used as biological markers in a testing strategy to detect residual PTx in vaccines. By microarrayanalysis we screened six human cell types (bronchial epithelial cell line BEAS-2B, fetal lung …

Om de diagnostiek van infecties met Clostridium difficile en Shigatoxineproducerende Escherichia coli (STEC) te verbeteren, is voor beide bacteriën een real-time PCR ontwikkeld. Dit verslag beschrijft het opzetten van de Clostridium-PCR en het valideren van zowel de Clostridium- als de STEC-PCR.

Matrix-assisted laser desorption/ionisation time of-flight mass spectrometry (MALDI-TOF MS) is a fast and reliable method for the identification of bacteria from agar media. Direct identification from positive blood cultures should decrease the time to obtaining the result. In this study, three different …

Carvacrol en cinnamaldehyde zijn etherische oliën en staan bekend om hun remmende effecten op micro-organismen. IRAS-VPH wil nagaan of de combinatie van organische zuren met carvacrol of cinnamaldehyde de remming op de Salmonella invasie in IPEC-J2 cellen nog verder kan verbeteren. Invloed van de stoffen …

Effects of systemic inflammation on cerebral function are not clear, as both inflammation-induced encephalopathy as well as stress-hormone mediated alertness have been described. Experimental endotoxemia (2 ng/kg Escherichia coli lipopolysaccharide [LPS]) was induced in 15 subjects, whereas 10 served …

Penicillin acylase (PA) from Escherichia coli can catalyze the coupling of an acyl group to penicillin- and cephalosporin-derived beta-lactam nuclei, a conversion that can be used for the industrial synthesis of beta-lactam antibiotics. The modest synthetic properties of the wild-type enzyme make it …

Amylomaltases or D-enzyme (4-α-glucanotransferases; E.C. 2.4.1.25) are carbohydrate-active enzymes that catalyze the transfer of glucan units from one α-glucan to another in a disproportionation reaction. These enzymes are involved in starch metabolism in plants or maltose/glycogen metabolism in many …
