BACKGROUND Chronic diseases cause a tremendous burden to the military medical system. However, the prevalence rates of major chronic diseases among military officers remain unclear in China. METHODS China National Knowledge Infrastructure (CNKI), Wanfang Database, VIP Database for Chinese Technical Periodicals (VIP), PubMed and Web of Science were searched for studies (from 2000 to 2016) conc...
Arterial ischemia and hemorrhage are associated with bevacizumab, an inhibitor of vascular endothelial growth factor that is widely used to treat many types of cancers. As specific types of arterial ischemia and hemorrhage, cerebrovascular events such as central nervous system (CNS) ischemic events and CNS hemorrhage are serious adverse events. However, increased cerebrovascular events have not...
BACKGROUND AND PURPOSE To develop recommendations for the establishment of comprehensive stroke centers capable of delivering the full spectrum of care to seriously ill patients with stroke and cerebrovascular disease. Recommendations were developed by members of the Brain Attack Coalition (BAC), which is a multidisciplinary group of members from major professional organizations involved with t...
Epileptic seizures are a common presentation in patients with newly diagnosed brain arteriovenous malformations, but the pathophysiological mechanisms causing the seizures remain poorly understood. We used magnetic resonance imaging-based quantitative cerebrovascular reactivity mapping and conventional angiography to determine whether seizure-prone patients with brain arteriovenous malformation...
Purpose: Cardiopulmonary resuscitation (CPR) is an important step for patient survival inside and outside the hospital. Therefore, the results of CPR can be effective in modifying the structure of this operation and in eliminating its shortcomings. The purpose of this study was to evaluate the success rate of CPR in intensive care unit of an Iran’s Army Air Force hospital in 2012. Mat...
Introduction: Aphasia is a common manifestation of stroke and evaluation of relationships of aphasia and brain topography could lead to better understanding of cognitive neurophysiology. Methods: 100 stroke patients with aphasia admitted in Valie-Asr hospital, Khorasan since April 2003 were enrolled in this prospective cross-sectional study. Diagnosis of stroke and aphasia was made by a neurol...
a significant problem in multicarrier communication systems is the necessity to reduce the value of papr (peak-to-average power ratio) of transmitting signal. in this thesis we study the effect of the system parameters such as coding and modulation types on papr and ultimate ber in a mc-cdma system. in this study we consider fading channel as well as the nonlinearity of transmitter’s amplifier ...
Peroxisome proliferator-activated receptor gamma (PPARγ) is emerging as a major regulator in neurological diseases. However, the role of (PPARγ) and its co-regulators in cerebrovascular endothelial dysfunction after stroke is unclear. Here, we have demonstrated that (PPARγ) activation by pioglitazone significantly inhibited both oxygen-glucose deprivation-induced cerebral vascular endothelial c...

Glutamate is one of the major neurotrasmitters in mammalian brain and changes in its concentration have been associated with a number of neurological disorders, including neurodegenerative, cerebrovascular diseases and epilepsy. Moreover, recently a possible role for glutamatergic system dysfunction has been suggested also in the peripheral nervous system. This chapter will revise the current k...
