Choledocholithiasis is a common disorder, especially in patients older than 60 years, as common bile duct stones may be present in 15% to 60% of cases in this special sample of population. Until recently, endoscopic retrograde cholangiography (ERC), which is a very reliable method for visualizing and extracting gallstones in the same session, was considered the gold-standard for suspected chole...
پارامتر rms پراکندگی تاخر یکی از پارامترهای مهم در طراحی سیستمهای مخابرات سیار می باشد. در این پایان نامه خصوصیات rms پراکندگی تاخیر در محیط تونل بررسی شده است . منحنیهای طیف توان تاخیری که برای محاسبه rms پراکندگی تاخیر در مکانهای مختلف مورد نیاز می باشند توسط شبیه سازی انتشار امواج داخل تونل با روش ray tracing محاسبه شده اند. مبنای روش ray tracing یافتن همه مسیرهای انتشاری بین فرستنده و گیرند...
ADIPOSE TISSUE DOES NOT SEEM to be innervated in any significant manner by the vagus nerve after all. As reported by Giordano et al. (9) in this issue, retrograde tracing with pseudorabies virus from at least one fat pad in the Siberian hamster reveals only the occasional neuron in the vagal motor nucleus and nerve fibers in adipose tissue of mouse, rat, and hamster do not exhibit any of the ma...
Background: Olfactory ensheathing glia (OEG) has been shown to have a neuroprotective effect after being transplanted in rats with spinal cord injury. This study was conducted to determine the possible beneficial results of olfactory mucosa transplantation (OMT) which is a source of OEG on functional recovery and axonal regeneration after transection of the sciatic nerve. Methods: In this study...
The urinary bladder trigone (UBT) is a limited area through which the majority of vessels and nerve fibers penetrate into the urinary bladder and where nerve fibers and intramural neurons are more concentrated. We localized the extramural post-ganglionic autonomic neurons supplying the porcine UBT by means of retrograde tracing (Fast Blue, FB). Moreover, we investigated the phenotype of sympath...
2 adrenergic receptor ( 2-AR) agonists have been used as antihypertensive agents, in the management of drug withdrawal, and as sedative analgesics. Since 2-AR agonists also influence the regulation of body temperature, we explored their potential as antipyretic agents. This study delineates the central neural substrate for the inhibition of rat brown adipose tissue (BAT) and shivering thermogen...
OBJECTIVE Temperature and nutrient homeostasis are two interdependent components of energy balance regulated by distinct sets of hypothalamic neurons. The objective is to examine the role of the metabolic signal insulin in the control of core body temperature (CBT). RESEARCH DESIGN AND METHODS The effect of preoptic area administration of insulin on CBT in mice was measured by radiotelemetry ...
