OBJECTIVE We describe the relation between the clamping time and blood volume collected, plus two enrichment systems for CD34+ stem cells from umbilical cord blood, to achieve an excellent recovery of cells with a high proliferative ability and bone marrow reconstitution. METHOD After cord blood collection by an obstetrician, stem cell purification has been performed either with a combination...

Fe deficiency is a common nutritional disorder during infancy, particularly in low-income countries. The Fe status of a breast-fed infant is strongly influenced by the body Fe content at birth, which is determined by factors that operate before birth (maternal Fe status before and during pregnancy; infant gestational age and birth weight) and at the time of delivery (the timing of umbilical cor...

Many common care practices during labor, birth, and the immediate postpartum period impact the fetal to neonatal transition, including medication used during labor, suctioning protocols, strategies to prevent heat loss, umbilical cord clamping, and use of 100% oxygen for resuscitation. Many of the care practices used to assess and manage a newborn immediately after birth have not proven efficac...

We appreciate the comments of Ioannis K. Toumpoulis about our paper concerning the use of immediate ischemic preconditioning based on somatosensory evoked potentials to prevent spinal cord injury [1]. In that study, it was shown that ischemic tolerance could be immediately achieved in the spinal cord against a clinically relevant ischemic insult, since ischemic preconditioning was based on the ...
