bilateral vocal cord paralysis is a rare and preventable complication of anterior cervical discectomy and fusion. herein, we report a fatal case of bilateral vocal cord paralysis after anterior cervical discectomy and fusion (acd/f). a 65-year-old man with cervical spine trauma and anterior cord syndrome, following car overturn presented to our emergency department. the patient had c6-t10 prola...

background: abnormal umbilical cord ph can be indicated a distress imposed of newborn and can also be useful in determining the prognosis of the newborn. there are different views about the effect of the neonatal delivery method on the blood gas analysis of the umbilical artery. this study aimed to determine the effect of the method of delivery on umbilical artery ph. methods: in this cross –se...

Objective(s): 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 ...

The authors present their experience in prenatal diagnosis of placental and umbilical cord pathologies, using three-dimensional ultrasound (3DUS) in the rendering and tomography ultrasound imaging (TUI) modes, associated with color Doppler in some cases. Cases of placenta accreta/placenta previa, circumvallate placenta, succenturiate lobe, true knot of the umbilical cord, nuchal cord, and margi...

cord blood hematopoietic stem cells are widely used as an alternative source for hematopoietic stem cells transplant. increasing rate of patients who need hematopoietic stem cells transplant and many advantages of cord blood in comparison to bone marrow hematopoietic stem cells, have promoted banking of cord blood units. cord blood banking requires accurate steps in donor selection, cord blood ...

The umbilical cord is a helical and tubular blood conduit connecting the foetus to the placenta. The umbilical cord achieves its final form by the 12th week of gestation and normally contains two arteries and a single vein, all embedded in Wharton's jelly. The structure of the umbilical cord receives only a cursory glance during many obstetric ultrasound examinations: with imaging limited to do...

BACKGROUND It has been established that presence of lean umbilical cord with reduced Wharton's jelly in sonographic scans is a fetal marker for risk of small for gestational age at birth. With improvement of ultrasound techniques, more studies have been investigating the alterations of the umbilical cord on pregnancy outcomes. OBJECTIVES To determine the reference ranges of the umbilical cord...

Background: The main objective of this study was to systematically review the reported potency of cord blood stem cells in treating patients with neurological disorders such as cerebral palsy.  Methods: PubMed, Scopus, and Cochrane were searched thoroughly on September 2016 using the following search terms: “Umbilical cord blood stem cells” AND “development” AND “cerebral palsy” to find articl...

background: human umbilical cord blood (hucb) is an acceptable and readily accessible source of stem cells. there is an ongoing interest in cord blood stem cell therapies; however, little is known about the possible unfavorable effects of laboratory modifications on the isolated hucb cells. the involvement of mirnas in several biological processes has been shown. the aim of this study was to ev...

background: in recent years we have successfully adopted an in vitro hepatogenic differentiation of mesenchymal stem cells (mscs). in this protocol the biologically active hepatocyte-like cells were differentiated from the stem cells isolated from either bone marrow or umbilical cord blood (ucb) samples. the aim of the present study was to compare the efficiency of the hepatogenic differentiati...
