n. 1) the date when the payment of the principal amount owed under the terms of a promissory note or bill of exchange becomes due. Quite often a note states that failure to pay interest or installment payments when due "accelerates" the note, making the "maturity date" immediate if such payments are demanded and not paid. 2) the age when one becomes an adult, which is 18 for most purposes. (See: promissory note, bill of exchange, acceleration, legal age)

Rapid fetal lung maturity testing: commercial versus NBD-phosphatidylcholine assay.
Corticosteroids may help target the inflammation associated with development of autoantibody-associated CHB as well as improve fetal lung maturity before premature caesarean delivery.
Rather, the obstetrician decided to wait several hours, as he felt that there was no emergency situation present and he wanted to allow time for the steroids to improve the infant plainntiff's fetal lung maturity. The obstetrician later made an independent decision, as the mother's treating physician, to perform the section, for which he took sole responsibility.
compile 56 chapters for all health professionals involved in the care of women with high-risk pregnancies that address such issues as nutrition, alcohol and substance abuse, and environmental agents and reproductive risk; genetic screening for Mendelian disorders and fetal aneuploidy and neural tube defects; monitoring fetal lung maturity, antepartum fetal monitoring, and interpreting intrapartum fetal heart tracings; and maternal diseases such as sickle cell anemia, cardiac disease, diabetes, asthma, epilepsy, hypertension, lupus, infections, hepatitis, and HIV.
Neonates who are delivered at 36-38 weeks' gestation after fetal lung maturity is confirmed have nearly double the risk of adverse outcomes, compared with neonates delivered at 39 or 40 weeks, a large retrospective cohort study has shown.
Previous studies of fetal lung maturity vary from ability to read news prints across test tubes containing amniotic fluid to quantitative LS ratio estimation (18).
Furthermore, elective delivery before 39 weeks' gestation generally is not recommended unless there is evidence of fetal lung maturity. Therefore, researchers sought to describe the timing of elective repeat cesarean deliveries and to assess the associations between the risk of adverse neonatal outcomes and such deliveries at term but before 39 weeks.
"Prednisone is preferred over dexamethasone because it doesn't cross the placenta--other steroids will cross and include the ones used to induce fetal lung maturity," he explained.
Once fetal lung maturity is achieved as measured by lecithin/sphingomyelin ratios or phosphotidal glycerol levels, delivery is suggested at approximately 38-39 weeks.
