Objective(s) Nicotinic acetylcholine receptors (nAChRs) regulate epileptiform activity and produce a sustained pro-epileptogenic action within the hippocampal slices. In the present study, we investigated the effect of nAChRs on evoked glutamatergic synaptic transmission in area CA3 and CA1 of rat hippocampal slices to identify possible excitatory circuits through which activation of nAChRs pr...

Objective: The main objective pursued in this paper is to investigate the energy consumption for drying of potato slices using vacuum-infrared drying method. Methods: Drying of potato slices with the thicknesses of 1, 2 and 3 mm were conducted at vacuum levels of zero (without vacuum), 20, 80 and 140 mm [Hg], infrared radiation at power levels of 100, 150 and 200 W in the three repetition. Resu...

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...

in this work, a hybrid gmdh–neural network model was developed in order to predict the moisture content of papaya slices during hot air drying in a cabinet dryer. for this purpose, parameters including drying time, slices thickness and drying temperature were considered as the inputs and the amount of moisture ratio (mr) was estimated as the output. exactly 50% of the data points were used for ...

  Effects of visual deprivation on the induction of epileptiform activity were studied in layer II/III of mature rat primary visual cortex. Field potentials were evoked by stimulation of layer IV in slices from control and dark-reared (OR) rats. Picrotoxin (PTX)-induced epileptic activity was characterized by spontaneous and evoked epileptic field potentials (EFPs). The results showed that OR s...

PURPOSE To date, myocardial perfusion cardiovascular magnetic resonance (CMR) has been reported in single and multiple short-axis slices. Three short-axis planes can assess 16 segments of the standard 17-segment myocardial model, but this approach fails to assess the ventricular apex that requires at least one long-axis plane. We therefore evaluated the feasibility and benefit of combined long-...

PURPOSE To evaluate the cement thickness around oval and circular posts luted in oval post spaces prepared with different drills/tips. METHODS Extracted premolars were endodontically treated and obturated, then randomly divided into three groups (n = 5) according to the tips/drills used for post-space preparation and to the type of fiber post luted: medium grit oval tip + oval posts, fine gri...

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...

The diterpene glycoside, atractyloside (ATR) is present in a number of plants used as popular medicines throughout Africa and along the Mediterranean. These plants cause fatal intoxication in a significant number of individuals [ 1-31. especially children. Clinical data from humans poisoned by these plants and experimental studies in animals treated with ATR have shown an acute cellular necrosi...
