Low-frequency oscillations in cerebral blood flow that are suggestive of resting-state brain activity have recently been reported, but no study on the development of resting-state brain activity in preterm infants has been performed. The objective of this study was to measure the cerebral blood flow oscillations, which are assumed to represent brain(More)
Dubin-Johnson syndrome (DJS) is an autosomal recessive inherited disorder characterized by conjugated hyperbilirubinemia. Neonatal-onset DJS is rare. It is caused by dysfunction of adenosine triphosphate-binding cassette, sub-family C, member 2 (ABCC2). We found a novel compound heterozygous mutation of DJS-related gene: W709R (T2145C): a missense mutation(More)
BACKGROUND The ratio of urinary coproporphyrin (UCP) I to total urinary coproporphyrin I and III [UCP {I/(I + III)]] serves as a biomarker of the ATP-binding cassette, sub-family C, member 2 (ABCC2) function. The aim of this study was to clarify the characteristics of the developmental pattern of UCP [I/(I + III)] in order to estimate ABCC2 function in(More)
BACKGROUND Measured unbound bilirubin concentration is influenced by bilirubin photoisomers. Bilirubin photoisomers are produced even with only a slight light exposure, and clinical samples are inevitably exposed to light. The objective of the study was to evaluate the influence of bilirubin photoisomers on the measurement of unbound bilirubin using serum(More)
