Human umbilical vein (HUV) endothelial cells were grown for 15 to 21 passages at a split ratio of 1:5 (at least 27 population doublings) on a human fibronectin (HFN) matrix in Medium 199 supplemented with fetal bovine serum (FBS) and endothelial-cell growth factor (ECGF). This system also permitted the growth of HUV endothelial cells at cell densities as low as 1.25 cells/cm2. In addition to de...

Aspergillus fumigatus infections are associated with a high mortality rate for immunocompromised patients. The complement system is considered to be important in protection against this fungus, yet the course of activation is unclear. The aim of this study was to unravel the role of the classical, lectin, and alternative pathways under both immunocompetent and immunocompromised conditions to pr...

Brain-derived neurotrophic factor (BDNF) is a neurotrophin essential for neuronal survival and differentiation. We examined the concentration of BDNF in cord serum from newborns exposed to methylmercury (MeHg) and polychlorinated biphenyls (PCB) in utero by maternal consumption of whale meat. The cohort consisted of 395 singleton births (206 boys and 189 girls), gestational age ranging from 38 ...

OBJECTIVE Most neonatal encephalopathic disorders appear to be caused by perinatal events. Persistent myocardial ischemia leads to cellular necrosis and release of troponin from cardiac muscles. Fetal distress during labor may be detected by monitoring the fetal heart rate. However little is known about the relationship, if any, that exists between fetal heart rate abnormalities and the fetal c...

AIM To examine the hypothesis that the maternal insulin-like growth factor system may constrain fetal growth. METHODS A prospective observational study of maternal serum insulin-like growth factor binding protein-1 (IGFBP-1) and fetal growth was undertaken in neonates with birthweights below the 5th centile. They had been classified either as having fetal growth restriction (FGR) due to place...

This study describes the results of testing 92 serum samples, including 10 umbilical cord serum samples, from 38 cytomegalovirus (CMV)-infected neonates for CMV-specific immunoglobulins E (IgE) and M by antibody-capture enzyme-linked immunosorbent assays with enzyme-labeled CMV antigen. All infants excreted CMV in the urine. It was demonstrated that the CMV IgE test was more sensitive than the ...

To investigate the protective effect of irudin on renal interstitial injury caused by proteinuria regulating core fucosylation modification using model microfluidic chip. Application tissue engineering soft lithography technology preparation with cavity proximal small pipe, tube Zhou Wei vascular lumen and area Polydimethylsiloxane chip material, in tubes each Human tubular epithelial cells umb...

OBJECTIVE Although mesenchymal stem/stromal cells represent a promising therapeutic strategy for acute respiratory distress syndrome, clinical translation faces challenges, including scarcity of bone marrow donors, and reliance on bovine serum during mesenchymal stem/stromal cell proliferation. We wished to compare mesenchymal stem/stromal cells from human umbilical cord, grown in xeno-free con...

AIM There are currently limited lipidomics data for human umbilical cord blood. Therefore, the lipidomes of cord sera from six newborns and sera from six nonpregnant females were compared. MATERIALS & METHODS Sera lipidomics analyses were conducted using a high-resolution mass spectrometry analytical platform. RESULTS Cord serum contained a diverse array of glycerophospholipids, albeit gene...
