Increased serum levels of unconjugated bilirubin are associated with the development of brain damage in newborns. In current clinical settings, there are no methods for directly determining serum levels of unconjugated bilirubin. UnaG, a fluorescent protein from Japanese eel muscle that specifically binds to unconjugated bilirubin was used in this study. Linear regression analysis was carried o...

The accuracy of transcutaneous bilirubin meters has been assessed in newborns from various ethnic backgrounds. However, there are limited data on Greek newborns. Our study examined the accuracy of transcutaneous bilirubin measurements in clinically jaundiced healthy-term Greek newborns, using total serum bilirubin as the reference standard, in order to re-evaluate our local guidelines about neo...

background: considering the increasing rates of early hospital discharge and kernicterus in healthy full term newborns, timely identification of neonates at risk of severe hyperbilirubinemia is of great significance. the aim of this study was to investigate the predictive value of umbilical cord serum (ucs) bilirubin level for subsequent hyperbilirubinemia. moreover, we compared the predictive ...

BACKGROUND Neonatal jaundice is the most frequently encountered diagnostic and therapeutic problem in the newborn. In the jaundiced infant, it is thought that the binding capacity of plasma albumin is exceeded, which allows free bilirubin to diffuse into and accumulate within extravascular tissues, such as the central nervous system. Affected newborns may develop kernicterus. The standard metho...

BACKGROUND Serum bilirubin has been consistently shown to be inversely related to cardiovascular disease (CVD). Recent studies showed serum bilirubin to be associated with CVD-related factors such as diabetes, metabolic syndrome, and body mass index. Although the association of serum bilirubin with CVD has been found in both retrospective and prospective studies, less information is available o...

The molar absorptivity of unconjugated bilirubin in caffeine reagent is independent of the protein matrix. This finding, together with the simplicity of a dilution step for direct spectrophotometry, will improve the calibration methods of bilirubin and make them more nearly accurate. This is encouraging for the development of a new method for bilirubin determination in neonates; moreover, the c...

background: maternal and neonatal factors could help determine the potential incidence of hyperbilirubinemia. in this study, we aimed to identify the relationship between the severity of jaundice in newborns and maternal and neonatal factors. methods: this descriptive, cross-sectional study was conducted in 2014. icteric newborns, admitted to qods and kowsar teaching hospitals in qazvin, iran w...

to evaluate the changes of abr values in hyperbilirubinemic newborns, 85 cases with severe jaundice (total bilirubin levels over 16 mg/dl and direct bilirubin less than 2 mg/dl) were selected from those admitted to children's medical center by simple sampling method. these infants had no other problem except jaundice. abr was taken before treatment in all cases and in some (10 cases) after...

Bilirubin is a standard serum biomarker of liver function. Inexplicably, it is inversely correlated with cardiovascular disease risk. Given the role of endothelial dysfunction in originating cardiovascular diseases, direct analysis of bilirubin in the vascular endothelium would shed light on these relationships. Hence, we used high-performance liquid chromatography coupled with thermal lens spe...
