Ligation and transection of the L5 spinal nerve in the rat lead to behavioral signs of pain and hyperalgesia. Discharge of injured nociceptors has been presumed to play a role in generating the pain. However, A fibers, but not C fibers, in the injured L5 spinal nerve have been shown to develop spontaneous activity. Moreover, an L5 dorsal root rhizotomy does not reverse this pain behavior, sugge...

Summary In order to determine the immunity state against Rubella in 10-19 year old women in urban and rural area of Chahar -Mahal Bakhtiari province of IRAN in act 1992. We have done a cross sectional seroepidemiologic study in 1347 women. This study showed a high rate of immunity against Rubella in this province. About 90.5% of studied population had protective antibody titer against Rubella...

Most neuronal networks, even in the absence of external stimuli, produce spontaneous bursts of spikes separated by periods of reduced activity. The origin and functional role of these neuronal events are still unclear. The present work shows that the spontaneous activity of two very different networks, intact leech ganglia and dissociated cultures of rat hippocampal neurons, share several featu...

OBJECTIVE It is unclear if resting metabolic rate (RMR) and spontaneous physical activity (SPA) decrease in weight-reduced non-obese participants. Additionally, it is unknown if changes in SPA, measured in a respiratory chamber, reflect changes in free-living physical activity level (PAL). RESEARCH METHODS AND PROCEDURES Participants (N = 48) were randomized into 4 groups for 6 months: calori...

Background: The relationship between air pollution exposure and adverse birth outcomes such as low birth weight and IUGR was studied. However, very few studies evaluated the effect of air pollution emissions on spontaneous abortion. We examined association between spontaneous abortion of the first trimester of pregnancy and ambient concentrations of carbon monoxide in Tehran. Materials and Meth...

customer activity has received more attention due to the increase of social network applications. moreover, customer activity could be an answer to the research debate about the significant relationship between retention rate and lifetime profitability of customers. several researchers believe that an increase in the retention rate of customers may enhance their customer lifetime value (clv), o...

Introduction: Dimethyl sulfoxide (DMSO) is a chemical often used as a solvent for waterinsoluble drugs. In this study, we evaluated the effect of intracerebroventricular (ICV) administration of DMSO on neural response characteristics (in 1200–1500 μm depth) of the rat barrel cortex. Methods: DMSO solution was prepared in 10% v/v concentration and injected into the later...
