The presence of nystagmus differentiates a high cervical cord and brainstem lesion in quadriplegic patient.

introduction: electrophysiologycal histological methods were for studing the anatomical distribution of group i and ii muscle afferent in the lumbosacral segments of wistar rat spinal cord. material and methods: quadriceps, deep proneal, hamestring, gastrocnemius-soleus, tibialis posterior, plantaris, flexor digitorum longus and popliteus muscle nerves were dissected and mounted on surface elec...

Background: The mammalian target of rapamycin (mTOR) is important in hematopoiesis. Despite the central role of mTOR in regulating the differentiation of immune cells, the effect of mTOR function on cord blood mononuclear cells is yet to be defined. Objectives: To evaluate the effect of mTOR inhibition, using rapamycin on the proliferation and apoptosis of cord blood mononuclear cells, as well ...

Umbilical cord blood (UCB) has been used for transplantation in the treatment of hematologic disorders as a source of hematopoietic stem cells (HSCs). Because of insufficient number of cord blood CD34+ cells, the expansion of these cells seems to be important for clinical application. Mesenchymal stromal cells (MSCs), playing an important role in HSCs maintenance, were used as feeder layer. Apo...

Introduction: Postoperative neurological deficit is the most devastating complication after thoracoabdominal aortic aneurysm repair. Despite demonstrated neuroprotective effects of estradiol, its protective efficacy against spinal cord ischemia-reperfusion and underlying mechanisms are not yet elucidated. Methods: Two groups, each of 10 New Zealand white male rabbits, were studied. Control g...

Bone loss after spinal cord injury leads to increased fragility of bone and subsequent risk for low-trauma fractures in the sublesional parts of the body. Although in such injuries upper limbs are normally innervated, bone loss may occur in the upper extremities. The present study was designed to determine the systemic effects of spinal cord injury on the fracture healing of upper limbs in rabb...

BACKGROUND Wound healing is a complex and dynamic process following damage in tissue structures. Due to extensive skin damage caused by burn injuries, this study determined the role of human adult peripheral and umbilical cord blood platelet-rich plasma on proliferation and migration in human skin fibroblasts. METHODS Platelet-rich plasma (5, 10, 15, 20 and 50% PRP) from human umbilica...

Introduction: Nasopharyngeal carcinoma is one of the most common malignancies in the head and neck region and radiotherapy is its treatment of choice. In spite of the fact that it is widely used, due to the presence of many sensitive organs or tissues in this region, patients may suffer from a wide range of side effects. One such sensitive tissue is the spinal cord. If the absorbed dose to spin...
