The initial experience concerning the use of magnetic resonance imaging in 94 patients who had sustained chronic cord injury showed its specific advantages over traditional imaging modalities. A variety of 84 cord abnormalities were identified including myelomalacia in 47%, cord cysts in 37%, focal atrophy in 11 % and cord transection in 5%. Canal stenosis was seen in twenty-five patients, ...
Purpose: This study was carried out to isolate mesenchymal stem cells from full-term cord blood and to differentiate these cells into osteoblastic cells. Materials and Methods: It this study, mesenchymal stem cells were isolated from cord blood and expanded by being cultured in the flask several times. First, the cord blood monoeuc1earcells were separated by ficoll - Hypac before they were cul...
Considering the extent of the disability caused by spinal cord injury and the increasing incidence of it, many attempts have been made to understand how this lesion is repaired. Most of the spinal cord injuries are traumatic injuries. The annual incidence of this damage is estimated between 15-40 cases per million people worldwide. Considering the extent of this incident, the need for study of ...
background: the aim of this research was to study the distribution and changes of glycoconjugates particularly their terminal sugars by using lectin histochemistry during mouse spinal cord development. methods: formalin-fixed sections of mouse embryo (10-16 fetal days) were processed for lectin histochemical method. in this study, two groups of horseradish peroxidase-labeled specific lectins we...
background: over the years, various types of orthoses have been designed to assist subjects with spinal cord injury (sci) to stand and walk. however, the functional performance of the orthoses has not been adequate, that is, patients experience stability problems, consume excessive energy during ambulation, and generally require assistance in donning and doffing the devices. this research is ai...
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...
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 ...
spinal cord injury (sci) is a destructive condition that the cord can't send signals below the level of the injury. despite advances in the medical and surgical care of sci patients, no effective treatment exists for the neurological deficits of sci. cell therapy is a new approach for sci, and preclinical models demonstrate that cell transplantation can improve some secondary events throug...
Abstract Background : Iatrogenic recurrent laryngeal nerve (RLN) injury is an uncommon but serious complication of Head and neck surgery and also thoracic procedures. laryngoscopy can be an invasive and uncomfortable procedure, therefore the use of sonography as an noninvasive method of screening patients for impaired vocal-cord mobility is desirable. The aim of this study was to assess ...
