...R. Dimenstein; N.M.F. Trugo; C.M. Donangelo; L.C. Trugo; A.S. Anastácio The placental transfer of retinol and β-carotene was assessed based on maternal serum, cord serum and placental levels at term parturition in women with adequate (n = 15; serum retinol > 20 μg/dl) and subadequate (n = 16...

...Richard D. Zachman; Greg Valceschini Low plasma retinol (vitamin A) in premature infants has been associated with bronchopulmonary dysplasia. Also, retinol (vitamin A) deñciency is characterized by loss of cilia and squamous metaplasia of the respiratory tract, similar to the histological lesions...

...T. Koskinen; P. Valtonen; I. Lehtovaara; R. Tuimala The concentrations of retinol (vitamin A) were measured in 36 samples of human amniotic fluid obtained near term. Mothers with normal pregnancy had higher amniotic fluid retinol levels than patients with diabetes or toxemia. The results indicate...

...H.K. Kylberg; D.E. Ong; F. Chytil Levels of the cellular retinol-binding protein (CRBP) were measured in extracts of rat small intestine from 1 day before birth to day 21 postnatally. Changes in the amount of CRBP per cell were observed. The highest levels were observed in the 1-day-old rat...

...Lennart Jansson; Bertil Nilsson The relations at birth between infant and maternal serum retinol, retinol-binding protein (RBP) and retinol/RBP molar ratio were investigated in 25 healthy term infants and their mothers. The mean serum levels of retinol and RBP were significantly higher...

... by vitamin A in fetal development, thereby inducing morphological alterations which manifest as FAS. This work begins to explore a possible interaction of ethanol with vitamin A in craniofacial development. Retinoid levels and the expression of cellular retinol-binding protein (CRBP) and retinoic acid...

..., and lungs and livers were collected. Concentrations of retinyl palmitate and retinol were significantly higher in the lungs of pups 5 h after administration of vitamin A compared with controls. There were no differences in concentrations of retinyl palmitate or retinol in livers. We conclude...
