Meckel's diverticulum complicating neonatal umbilical cord clamping.
Amale neonateweighing 3838 g was born at 39weeks of gestation by elective cesarean delivery due to breech presentation. The umbilical cord was clamped by the surgeon approximately 20 cm from the umbilical base and the neonate was transferred to the midwife for final clamping. The cord was clamped again at approximately 3 cm from the umbilical base. The residual umbilical cord was approximately ...
متن کاملMesenchymal stem cells from umbilical cord tissue as potential therapeutics for cardiomyodegenerative diseases – a review
Heart failure is one of the leading causes of death worldwide. End stage disease often requires heart transplantation, which is hampered by donor organ shortage. Tissue engineering represents a promising alternative approach for cardiac repair. For the generation of artificial heart muscle tissue several cell types, scaffold materials and bioreactor designs are under investigation. In this revi...
متن کاملTesting Times in Toxicology – In Vitro vs In Vivo Testing
“Absence of evidence is no evidence of absence” – Carl Sagan, US astronomer (1934-1996) In the context of animal toxicity testing Hartung and McBride (2011) evoked the above quote to explain the fallacies we see in live animal testing. However, for reasons unknown or maybe due to the lack of better and more humane testing strategies, animal testing was in the past and, unfortunately, continues ...
متن کاملImmunogenicity of umbilical cord tissue derived cells.
Umbilical cord tissue provides a unique source of cells with potential for tissue repair. Umbilical cord tissue-derived cells (UTCs) are MHC class I (MHCI) dull and negative for MHC class II (MHCII), but can be activated to increase MHCI and to express MHCII with IFN-gamma stimulation. Mesenchymal stem cells with similar characteristics have been inferred to be nonimmunogenic; however, in most ...
متن کاملUmbilical cord and visceral hemangiomas diagnosed in the neonatal period
BACKGROUND Umbilical cord hemangioma is very rare and may not be detected prenatally. However, it should be considered in differential diagnosis with other umbilical masses because it can cause significant morbidity. METHODS We report the case of a newborn referred with suspected omphalitis and umbilical hernia. RESULTS Physical examination showed an irreducible umbilical tumor, the size of...
