- Comparison of L-serine uptake by human placental microvillous membrane vesicles and placental villous fragmentsA P Brand
Institute of Developmental Sciences, University of Southampton, School of Medicine, UK
Placenta 31:456-9. 2010..This study suggests that uptake of L-serine into MVM vesicles and villous fragments via Systems A and L is comparable, but that this is not true for all components of L-serine uptake...
- Review: Modelling placental amino acid transfer--from transporters to placental functionR M Lewis
University of Southampton, Southampton General Hospital, Faculty of Medicine, MP 887, Tremona Road, Southampton SO14 6BD, UK

Department of Clinical Biochemistry, Addenbrooke s Hospital, University of Cambridge, UK
Br J Nutr 85:193-201. 2001..These changes in fetal metabolism may contribute to fetal growth retardation in this model. This study does not support the hypothesis that the Fe-restricted fetus is hypoxic...
