  Background & Aim : Intrauterine growth retardation (IUGR) and preterm birth are major determinants of prenatal morbidity and mortality. Standard diagnostic methods like ultrasound are accurate, but they cannot be employed as the screening tools. Lately, it is proposed that there might be an association between IUGR and placental dysfunction so its hormones such as human chorionic gonadotropin...

BACKGROUND The strong anti-oxidative properties of bilirubin largely explain its cardioprotective effects. Insulin resistance is featured by low circulating bilirubin. Thyroid hormone affects both bilirubin generation and its biliary transport, but it is unknown whether circulating bilirubin is associated with thyroid function in euthyroid subjects. Aim is to determine relationships of bilirubi...

In the hard edge scaling limit of Jacobi unitary ensemble generated by weight xα(1 − x)β, x ∈ [0, 1], α, β > −1, probability that all eigenvalues Hermitian matrices from this lie in interval [t, 1] is given Fredholm determinant Bessel kernel. We derive constant asymptotics kernel determinant. A specialization results gives (− a, a), a 0 free with symmetric (1 x2)β, [− 1, 1].

OBJECTIVE To examine the distribution of maternal serum pregnancy-associated plasma protein-A (PAPP-A) and free β-human chorionic gonadotropin (β-hCG) at 12, 22 and 32 weeks' gestation in singleton pregnancies which develop pre-eclampsia (PE) and examine the performance of these biomarkers in screening for PE. METHODS Serum PAPP-A and free β-hCG were measured in 94 989 cases at 11-13 weeks, 7...

OBJECTIVE To define the contribution of maternal variables which influence the measured level of maternal serum free β-human chorionic gonadotropin (β-hCG) in screening for pregnancy complications. METHODS Maternal characteristics and medical history were recorded and serum free β-hCG was measured in women with a singleton pregnancy attending for three routine hospital visits at 11 + 0 to 13 ...
