We explored a potential mechanism linking placental prostaglandins (PGs) with a fall in plasma progesterone and increased expression of uterine activation proteins in the mouse. PG endoperoxide H synthase 2 (PGHS-2) mRNA expression increased in placenta in late gestation in association with an 8-fold increase in PGF(2alpha) concentration, reaching a peak on Gestational Day (GD) 18. This peak co...

Low birth weight is a key determinant in the risk of morbidity and mortality in the neonatal period and during childhood. This unmatched case-control study in Hamadan, Islamic Republic of Iran, compared the characteristics of mothers of low- and normal-birth-weight infants. Maternal sociodemographic data, pregnancy history, anthropometric data and cord plasma zinc level were collected from 134 ...

Background Neonatal mortality comprises a large part of infant mortality, and it depends largely on neonatal birth weight. Besides maternal diseases, it seems that other important factors such as maternal demographic characteristics, mental health and marital satisfaction, affects their infants birth weight. This study conducted aiming to evaluate these affecting factors on neonatal birth weig...

Background: Maternal nutrition during pregnancy affects the birth weight of neonates. Some of the undesirable pregnancy outcomes are linked to lower birth weights. This study aimed to assess the relationship between maternal dietary patterns, weight gain during pregnancy and nitric oxide (NO), as an endothelial relaxing factor, and the possible effects on birth weight.Materials and Methods: At ...
