Current solutions for the monitoring of pulmonary artery pressure (PAP) in patients suffering from pulmonary hypertension are limited to invasive means. Non-invasive alternatives, such as Doppler echocardiography, are incompatible with continuous monitoring due to their dependency on qualified personnel to perform the measurements. In the present study, a novel non-invasive and unsupervised approach based on the use of electrical impedance tomography (EIT) is presented. The approach was evaluated in three healthy subjects undergoing hypoxia-induced variations in PAP...

Human cytosolic sulfotransferase 1C4 (hSULT1C4) is a dimeric Phase II drug-metabolizing enzyme primarily expressed in the developing fetus. SULTs facilitate the transfer of a hydrophilic sulfonate moiety from 3'-phosphoadenosine-5'-phosphosulfate (PAPS) onto an acceptor substrate altering the substrate's biological activity and increasing the compound's water solubility. While several of the hSULTs' endogenous and xenobiotic substrates have been identified, the physiological function of hSULT1C4 remains unknown...

Virulence genes from different E. coli pathotypes are blended in hybrid strains. E. coli strains with hybrid enteroaggregative/uropathogenic (EAEC/UPEC) genotypes have sporadically emerged causing outbreaks of extraintestinal infections, however their association with routine infections is yet underappreciated. We assessed 258 isolates of E. coli recovered from 86 consecutive cases of extraintestinal infections seeking EAEC and hybrid genotype (EAEC/UPEC) strains. Extensive virulence genotyping was carried out to detect 21 virulence genes, including molecular predictors of EAEC and UPEC strains...

Protein tyrosine sulfation (PTS) is a widespread posttranslational modification that induces intercellular and extracellular responses by regulating protein-protein interactions and enzymes activities. Although PTS affects numerous physiological and pathological processes, only a small fraction of the total predicted sulfated proteins has been identified to date. Here, we localized the potential sulfation sites of Escherichia coli proteins on a proteome microarray by using a 3'-phosphoadenosine 5'-phosphosulfate (PAPS) synthase-coupled tyrosylprotein sulfotransferase (TPST) catalysis system that involves in situ PAPS generation and TPST catalysis...

In this study, an enzyme-based electrochemical method was developed for the detection of Escherichia coli (E. coli) using the T7 bacteriophages engineered with lacZ operon encoding for beta-galactosidase (β-gal). The T7lacZ phages can infect E. coli, and have the ability to trigger the overexpression of β-gal during the infection of E. coli. The use of the engineered phages resulted in a more sensitive detection of E. coli by (1) overexpression of β-gal in E. coli during the specific infection and (2) release of the endogenous intracellular β-gal from E...
