Introduction: Plastination is a unique technique for preservation of biological specimens used for teaching purposes. The protocol of flexible sheet plastination includes fixation, slicing, dehydration, force impregnation, casting, and curing (Hajian, Rabiei, Fatollahpour & Esfandiary, 2008). The procedure is done by using P87 flexible unsaturated polyester resin and provides heavy, gross, frag...

objective(s) bupropion is an atypical antidepressant that is widely used in smoke cessation under fda approval. the study of synaptic effects of bupropion can help to finding out its mechanism(s) for stopping nicotine dependence. in this study the effects of perinatal bupropion on the population spike (ps) amplitude of neonates were investigated. materials and methods hippocampal slices were pr...

introduction: the hippocampus was recognized as an important focus of epileptic seizures. a long-term potentiation (ltp) like that of epileptiform activities is considered as synaptic which has been observed for the first time in hippocampal formation. the purpose of the present study was investigating the synaptic plasticity induced by tetanic stimulation at ca1 area of the rat hippocampal sli...

An existing cryopreservation method for liver slices applies 12% dimethylsulfoxide and rapid freezing. We found that cells in rat liver slices cryopreserved in this manner deteriorated rapidly upon culturing. To improve this cryopreservation method, we varied the dimethylsulfoxide concentration (0, 12, 18, and 30%), the cryopreservation medium (Williams medium E, fetal calf serum, and Universit...

this research, presents mathematical modeling of drying process of aloe vera slices with dimensions of 7×4×0.5±0.1 cm. peeled aloe vera slices with the initial moisture content of 5750% (d.b) were osmosed for 5 hours in nacl solution of 10% and temperature of 40 °c at a constant solution to fruit ratio of 5:1. osmosed and unosmosed aloe vera samples were hot air dried at 55, 70 and 85°c with di...
