PURPOSE OF REVIEW Spinal cord ischemia after thoracoabdominal aortic interventions is a devastating complication because it significantly worsens the perioperative morbidity and mortality. Long-term outcome is also affected because of medical complications which are directly related to the neural deficits. Paraplegia has significant medical, social, and financial aspects. Limited mobility, the ...

a:4:{s:10:"Background";s:2314:"The research made on stem cells through the last decade and following that the great achievements made applying stem cells in treating vast number of diseases have turned the issue of Cord Blood collecting and saving (cryopreserving) to a critical one. A prompt demand and access to stem cells and applying them in treating a wide range of terminal diseases have led...

background: umbilical cord blood (ucb) is an alternative source of hematopoietic stem cell transplantation (hsct), used in leukemia treatment. cd26+ cells, a fraction of cd34 positive cells, are a major population of ucb cells which negatively regulate the in vivo homing and engraftment of hscs. cd26 is highly expressed in various cells such as hscs, immune cells, fibroblasts, and epithelial ce...

Background: Breast milk can be a source of toxic material, along with the transfer of nutrients needed for infant growth. This study was conducted to measure the level of lead in maternal and neonatal blood and breast milk in Tehran, Iran.Methods: In this cross-sectional study, 150 mothers and their infants were studied. Samples of maternal blood, fetal umbilical cord blood, breast milk, ...

Abstract Background B cells play an important role in the immune system due to production of the immunoglobulin and secreting several cytokines. It has been shown that B cells produced successfully in the presence of stem cell factor (SCF) and Flt3 ligand (Flt3L). IL2, IL7, and IL15 cytokines as -common family have an essential cytokines may support either synergistically or in an additive m...

objective: to compare the maternal and umbilical cord serum selenium concentrations in low and normal birth weight neonates. materials and methods: a case-control study was carried out in vali-asr and akbarabadi hospitals (jan. to dec. 2013). two groups; case group; 91 mothers who delivered a low birth weight (lbw) neonate and control group; 86 subjects who delivered a normal birth weight neona...

Surgery of the descending and thoracoabdominal aorta has been associated with post-operative paraparesis or paraplegia. Different strategies, which can be operative or non-operative, have been developed to minimise the incidence of neurological complications after aortic surgery. This review serves to summarise the current practice of spinal cord protection during surgery of the descending thor...

s:3604:"During pregnancy, the placenta delivers "cord blood" to the baby through the umbilical cord serving as a lifeline of nourishment from the mother to baby. At birth, "cord blood" remains in the umbilical cord and placenta and until recently, had typically been discarded. The tragedy of this practice is that "cord blood" contains very special cells called "stem cells". Recent advances in m...
