in this scientific research, for the first time, the removal of radioactive strontium-90 (90sr) by γ-mno2-aga zeolite as a novel nanocomposite adsorbent was accomplished under different conditions such as ph, temperature, adsorbent amount and the contact time that are examined from drinking water of ramsar city and monitored via ultra low-level liquid scintillation counting (lsc) technique. pri...

background: vitamin d deficiency during pregnancy is associated with some adverse pregnancy outcomes but its relationship with fetal growth is unknown. objective: we compared the 25-hydroxy vitamin d levels between mothers and their small for gestational age (sga) newborns with mothers and their appropriate for gestational age (aga) newborns. materials and methods: the study population included...

The objective of this longitudinal retrospective study was to evaluate differences of the fetal growth and fetal organ growth among singleton small for gestational age (S-SGA), singleton appropriate for gestational age (S-AGA), twin (Tw-AGA), and triplet (Tri-AGA) infants. Ultrasonographic examinations were performed on 35 S-AGA, 18 S-SGA, 52 Tw-AGA and 12 Tri-AGA fetuses. Circumferences of hea...

Glycosylasparaginase uses an autoproteolytic processing mechanism, through an N-O acyl shift, to generate a mature/active enzyme from a single-chain precursor. Structures of glycosylasparaginase precursors in complex with a glycine inhibitor have revealed the backbone in the immediate vicinity of the scissile peptide bond to be in a distorted trans conformation, which is believed to be the driv...

background: there is an assumption that fetus with restricted growth with an inappropriate intrauterine environment lies under stress. although small-for-gestational-age (sga) infants have higher mortality, difference in the outcome of sga and appropriate-for-gestational-age (aga) infants regarding respiratory morbidity is controversial. it seems that respiratory morbidities in sga neonates is ...

BACKGROUND Preterm small for gestational age (SGA) infants may be at risk for increased adiposity, especially when experiencing rapid postnatal weight gain. Data on the dynamic features of body weight and fat mass (FM) gain that occurs early in life is scarce. We investigated the postnatal weight and FM gain during the first five months after term in a cohort of preterm infants. METHODOLOGY/P...
