The urine of untreated phenylketonurics in the first weeks of life contains gamma-glutamylphenylalanine (0.07--0.69 mmol/g creatinine, 12 samples) visible on the normal 2-dimensional electrophoreto-chromatogram. This compound is less prominent or absent when urine from older untreated phenylketonurics is examined and

The concentration of intratesticular testosterone (IT-T) required for human spermatogenesis is unknown because spermatogenesis can persist despite the markedly reduced IT-T concentrations observed with LH suppression. Methods to lower IT-T further are needed to determine the relationship between IT-T and

17beta-Hydroxysteroid dehydrogenase type 7 (17beta-HSD7) catalyzes the reduction of estrone (E(1)) into estradiol (E(2)) and of dihydrotestosterone (DHT) into 5alpha-androstane-3beta,17beta-diol (3beta-diol), therefore modulating the level of mitogenic estrogens and androgens in humans. By classical and parallel chemistry, we generated several

No significant differences were found in plasma concentrations and urinary excretion of prostaglandin E2 (PGE2), 6-keto-prostaglandin-F1 alpha (6-keto-PGF1 alpha) and thromboxane B2 (TxB2), between rheumatoid arthritis patients and controls. However, urinary excretion of PGEe and 6-keto-PGF1 alpha tended to be

Congenital adrenal hyperplasia (CAH) is an autosomal recessive disorder most commonly caused by defects in the CYP21A2 gene. Neonatal CAH-screening based on 17-hydroxyprogesterone (17-OHP) measurements prevents life-threatening salt wasting conditions in newborns, but results in a considerable false-positive rate. Therefore
