In this study we examined estrogenic activity of styrene oligomers after metabolic activation by rat liver microsomes. Trans-1,2-diphenylcyclobutane (TCB), cis-1,2-diphenylcyclobutane (CCB), 1,3-diphenylpropane, 2,4-diphenyl-1-butene, 2,4,6-triphenyl-1-hexene, and 1-alpha-phenyl-4ss-(1 -phenylethyl)tetralin were negative in the yeast estrogen screening assay and estrogen reporter assay using es...

BACKGROUND AND OBJECTIVE Transcutaneous bilirubin (TcB) devices are widely used for the estimation of serum bilirubin levels in term and near-term infants. Our objective was to review the diagnostic accuracy of TcB devices in preterm infants. METHODS Medline, Embase, Cochrane library, Cumulative Index to Nursing and Allied Health Literature, and Scopus were searched (from database inception d...

OBJECTIVES To develop and validate a predischarge risk stratification model by using transcutaneous bilirubin (TcB) values and clinical factors to predict significant postdischarge hyperbilirubinemia in healthy term and late preterm Chinese neonates. METHODS In a prospective cohort study, 8215 healthy term and late preterm neonates in 8 hospitals in China underwent TcB measurement at <168 hou...

BACKGROUND Newborns are being discharged from hospitals within 1-2 days of birth, before hyperbilirubinemia usually becomes clinically evident. We investigated the use of transcutaneous bilirubin (TcB) before discharge to determine whether it affects the use of laboratory bilirubin testing or decreases the number of neonates readmitted for hyperbilirubinemia within 7 days of initial discharge. ...

Carcinoembryonic antigen T cell bispecific antibody (CEA TCB) is a bispecific antibody used to recognize CEA and CD3e via a novel molecular format (2:1) that induces T cell-mediated killing of CEA over-expressing tumors while sparing primary cells with low CEA expression. CEA TCB treatment inhibits tumor growth and generates a highly inflamed tumor microenvironment.

OBJECTIVE The objective of this study was to evaluate the roles of production and conjugation of bilirubin, individually and in combination, in the mechanism of neonatal jaundice. METHODS A cohort of healthy, term male newborns was sampled on the third day of life, coincident with routine metabolic screening, for blood carboxyhemoglobin determination, a reflection of heme catabolism, and for ...

the gold standard to assess jaundice in neonates is the serum bilirubin measurement. blood sampling for the determination of total serum bilirubin (tsb) is painful for newborns and stressful for parents. the bilicheck®, a new transcutaneous bilirubinometer, is considered as a more accurate measurement of bilirubin compared to the previous bilirubinometers courtesy of its advanced technology. th...

Background: Transcutaneous bilirubinometry (TCB) is a simple method for estimating bilirubin levels in neonates. This method is noninvasive, quick, and painless. We aimed to compare serum and cutaneous bilirubin measurements in term neonates.Method: In this descriptive cross-sectional study, 200 neonates with icter with birth weights of at least 2500 grams were studied. TCB was measured using a...
