چکیده سابقه و هدف برنامههای جدیدی برای درمان سرطان مدنظر محققین بوده و یکی از این رویکردها، تحویل هدف دار مواد سمی به سلولهای سرطانی میباشد. در ایمونوتوکسینها از قسمت سیتوتوکسیک توکسین ( دومین کاتالیتیک) باکتری یا گیاه و حذف قسمت اتصال دهنده و جایگزینی آن با یک لیگاند اختصاصی برای یک گیرنده سلولی استفاده میشود. در مطالعه قبلی یک ایمونوتوکسین جدید، شیگاتوکسین ـ CSF ـ GM ، طراحی و در ...
بررسی اثر مایع مغزی-نخاعی جنینی بر تمایز عصبی سلول های بنیادی مشتق از بافت چربی در رت نر نژاد ویستار
با توجه به اینکه اکثرفاکتورهای رشد نوروتروفیک موجود در csf جنینی مشابه فاکتورهای رشدی می باشد که تمایز نورونی را در سلول های بنیادی القا می کند ونظر به اینکه تمایز سلول های بنیادی مشتق از بافت چربی تحت تاثیر فاکتورهای مختلف به سمت رده های عصبی مختلف می رود ، با یک فرضیه منطقی می توان انتظار داشت که سلولهای بنیادی مشتق از بافت چربی تحت تاثیر csf جنینی به سمت رده های عصبی تمایز یابند.
the absence of cerebrospinal fluid (csf) pleocytosis in invasive meningococcal disease (imd) has been associated with an increased risk of death. it is unknown whether patients who lack a cellular response to central nervous system (cns) infection are at the same risk of adverse outcome as patiens without cns infection. to determine the frequency of presentation and outcome of three groups of c...
Background &Aim: The endoscopic endonasal transsphenoidal approach has been widely employed as a treatment for pituitary adenomas and other parasellar tumors. However, the major concerns related to endoscopic endonasal transsphenoidal surgery include the risks of CSF leak post-operatively leading to morbidity and at times mortality due to severe meningitis. Several studies in the past have foun...
Background: Stroke is the third leading cause of death. Hypothermia has been recognized as an effective method in reducing brain injury. In this study, we assessed the effects of granulocyte colony-stimulating factor (G-CSF) as a neuroprotective agent and mild hypothermia on mortality, behavioral function, infarct volume, and brain edema in Wistar rats. Methods: Forty male rats were used in fiv...
Project management is an important factor to accomplish the decision to implement large-scale software systems (LSS) in a successful manner. The effective project management comes into play to plan, coordinate and control such a complex project. Project management factor has been argued as one of the important Critical Success Factor (CSF), which need to be measured and monitored carefully duri...
Meningitis is one of the most common infectious cerebral nervous system (CNS), defined as an inflammation of the meninges. It is clinically categorized into a chronic and acute based on the acuity of symptoms. Vomiting, bulging fontanel and fever are the main symptoms in the patients with meningitis. Bacterial meningitis is a severe, potentially life-threatening infection that is associated wit...
Human granulocyte colony stimulating factor (hG-CSF) induces proliferation and differentiation of granulocyte progenitor cells. This glycoprotein is currently being used for treatment of neutropenia, in patients who have undergone bone marrow transplantation. So far, different researchers have tried to enhance hG-CSF biological activity and stability. In this study, Polymerase Chain Reaction (P...
Background & Aim: Levels of lactic dehydrogenase(LDH) in the cerebrospinal Fluid(CSF) have been used to evaluate a variety of neurologic disorders. However, few studies have been performed on neonates. The aim of this study was to detect levels of this enzyme in normal neonates. Patients and Methods: In this descriptive study, CSF samples were collected from 94 febrile infants 46 aged 0-4 w...
meningitis is an inflammation of the membranes that surround the brain and spinal cord, thereby involving the arachnoid, the pia and the cerebrospinal fluid (csf). it is divided into viral and bacterial meningitis. for different reasons the diagnosis of bacterial meningitis is very important. the examination of csf samples may provide information about causative microorganism. the sensivity of ...
