background the aim of this study was the ex vivo expansion of umbilical cord blood hematopoietic stem cells on biocompatible nanofiber scaffolds. materials and methods cd133+ hematopoietic stem cells were separated from umbilical cord blood using midimacs (positive selection) system by means of monocolonal antibody cd133 (microbeads) subsequently, flowcytometry method was done to assess the pur...

background: leptin is a protein product of obesity gene and is synthesized mainly by adipose tissue. objective: the aim of this study was to determine maternal and neonatal serum leptin levels in term preeclamptic and normal pregnancies. materials and methods: this cross sectional study was performed on 37 preeclamptic and 40 normotensive term pregnant women without other disease. serum level o...

OBJECTIVES Umbilical cord blood is a good source of the mesenchymal stem cells that can be banked, expanded and used in regenerative medicine. The objective of this study was to test whether amniotic membrane extract, as a rich source of growth factors such as basic-fibroblast growth factor, can promote the proliferation potential of the umbilical cord mesenchymal stem cells. MATERIALS AND ME...

Umbilical cord entanglement has been reported to occur in monoamniotic twins. However, it can occur in diamnionic twins due to rupture of the intertwin-dividing membrane, and is a cause for concern. A 31-year-old nullipara visited our hospital at 28+3 weeks gestation. A monochorionic diamniotic twin gestation was diagnosed ultrasonographically by visualizing a thin intertwin-dividing membrane a...

conclusion our study revealed that the hypoplastic umbilical artery group’s non-dominant cia had higher ri values than the contralateral dominant cia. results eleven of the 165 patients (6.7%) demonstrated a hypoplastic umbilical artery. second-trimester us showed median dominant and non-dominant cia pi values of 1.43 and 1.60 (p = 0.062), respectively, and median dominant and non-dominant cia ...

Introduction ▼ An aneurysm is a sac formed by localized dilatation of the wall of an artery, a vein, or the heart and the most common site is the abdominal aorta (Dorland’s Medical Dictionary, 32nd Edition, ­Elsevier,­ 2013)­ and­ is­ differentiated­ from­ an­ intra-abdominal­ ­umbilical­vein­varix­that­may­be­seen­as­a­cyst­-like­structure­in­ the­ fetal­ upper­ abdomen­ with­ venous­ flow­ on...

Gastroschisis has been defined as a malformation of the abdominal wall that classically presents visceral herniation with presence an intact umbilical cord and absence membrane covering content. Its exact etiology is unknown; however, it recognized multifactorial inheritance pattern. Recently, increase in number cases observed worldwide, particularly Mexico, which why some authors propose It si...
