Introduction: Controversial results have been reported about the effect of morphine and stress on learning and spatial memory in rodents. There are very few studies about the effects of ultra low doses of morphine on memory. In this study, effects of acute administration of low and usual doses of morphine on memory formation and retention in the presence and absence of repeated stress w...
introduction exposure to chronic levels of ionizing radiation could be detrimental to health even at very low doses. calabar free trade zone (cftz) was established to promote export business in nigeria and it is yet to produce exposure data of the zone. materials and methods the zone was divided into three categories depending on the type of business. category a had facilities with manufacturin...
Classic antidepressants have been known to induce convulsive seizures and nonconvulsive status epilepticus (NCSE). On the other hand, many reports have emphasized the safety of novel antidepressants. However, we encountered three cases of NCSE in the elderly associated with the use of newer antidepressants at therapeutic doses. All three patients were male and were 73 years of age or older. One...
In this research, the effects of packaging with two types of polymeric films (Low density polyethylene and polypropylene) and three gas compositions (Air, 20% CO₂ + 60% O₂ and 20% CO₂ + 5% O₂) on quantitative and qualitative attributes and storage life of cornelian cherry fruits were evaluated. Also some fruits in containers without cap were considered as control. After treatment, the fruits w...

by producing undistorted three-dimensional images of the area under examination, cone-beam computed tomography (cbct) systems have met many of the limitations of conventional radiography. these systems produce images with small field of view at low radiation doses with adequate spatial resolution that are suitable for many applications in endodontics from diagnosis to treatment and follow-up. t...
