Journal ArticleDOI
Morphological and molecular characterization of novel population of CXCR4+ SSEA-4+ Oct-4+ very small embryonic-like cells purified from human cord blood: preliminary report
Magda Kucia,M. Hałasa,Marcin Wysoczynski,Magdalena Baskiewicz-Masiuk,S Moldenhawer,Ewa K. Zuba-Surma,Ryszard Czajka,W Wojakowski,Bogusław Machaliński,Mariusz Z. Ratajczak +9 more
TL;DR: By employing a novel two-step isolation procedure – removal of erythrocytes by hypotonic lysis combined with multiparameter sorting – this work could isolate from CB a population of human cells that are similar to murine BM-derived VSELs, described previously.
Journal ArticleDOI
Maternal serum proinflammatory cytokines in preterm labor with intact membranes: neonatal outcome and histological associations
Andrzej Torbé,Ryszard Czajka,Agnieszka Kordek,Rafał Rzepka,Sebastian Kwiatkowski,Jacek Rudnicki +5 more
TL;DR: IL-1beta seems to be of moderate value in the prediction of histological chorioamnionitis, and the value of the other cytokines studied, was poor.
Journal ArticleDOI
Are vaginal fluid procalcitonin levels useful for the prediction of subclinial infection in patients with preterm premature rupture of membranes
Andrzej Torbé,Ryszard Czajka +1 more
TL;DR: To determine whether the procalcitonin concentrations are of value in the diagnosis of pPROM cases suspected of subclinical intrauterine infection or in the prediction of the pPRom‐to‐delivery interval.
Journal ArticleDOI
Circulating endothelial progenitor cells in premature infants: is there an association with premature birth complications?
Krzysztof Safranow,Maciej Kotowski,Joanna Lewandowska,Anna Machalińska,Violetta Dziedziejko,Ryszard Czajka,Zbigniew Celewicz,Jacek Rudnicki,Bogusław Machaliński +8 more
TL;DR: EPCs may play a considerable role in vascular development in preterm infants, and a positive association between the early-EPC count and the risk of respiratory distress syndrome, retinopathy of prematurity, bronchopulmonary dysplasia, and infections was found.
Journal ArticleDOI
Reliability of semiquantitative determination of procalcitonin serum concentrations in neonates.
TL;DR: The semiquantitative BRAHMS PCT-Q test reveals satisfactory concordance with the quantitative method when results in the next category are included to account for readout error, and is rapid, easy to use, and helpful as a supportive test when the quantitative assay is not available.
