The superficial cells of the entorhinal cortex (EC), main input to the hippocampus, receive a serotonergic input from the raphe nuclei and express 5-hydroxytryptamine creatine sulfate complex (5-HT) receptors at high density. With the use of intracellular recordings, we investigated the effects of serotonin on synaptic inhibition of layer II and III neurons of the EC. Serotonin reduced both pol...

Hippocampal dentate gyrus reactivity to perforant path (PP) stimulation in the anesthetized rat was enhanced after systemic administration of the serotonin-releasing drug fenfluramine (FFA). This effect of FFA was mimicked by local application of the drug via the recording pipette, indicating that the effect of FFA is mediated by release of serotonin from intrahippocampal serotonergic terminals...

Non-ammonia nitrogen (NAN) passage to the small intestine and disappearance of NAN in that organ have been studied in multi-cannulated sheep on pasture or fed indoors. Forages under investigation included a number of subtropical grasses, foggages and hay, temperate grasses, lucerne (Medicago sativa), triticale (Triticale X Secale), oven-dried ryegrass (Lolium multiflorum), and the tannin-contai...

Recent studies suggest that the anabolic effects of testosterone in muscle may be mediated, in part, by the insulin-like growth factor (IGF) system. The aim of this study was to examine the effects of nandrolone (NAN) on both IGF-I and IGF-binding proteins (IGFBPs) in the diaphragm muscle of 1-yr-old female rats. NAN (6.6 mg. kg(-1) x day(-1)) was infused continuously for 17 days using a subcut...

Acute pancreatitis was induced in mice by feeding with a choline-deficient ethionine-supplemented diet. All the mice developed acute pancreatitis, and approximately 80% of them died within 4 days. Stereomicroscopic and light microscopic examinations revealed that pancreatic necrosis and circulatory disturbance that were not apparent on day 1 were increased markedly on days 2 and 3. Serum levels...

Effects of sodium azide (NaN(3)) on spontaneously generated action potential and bursts of potential elicited by d-amphetamine (d-amphetamine-elicited BoP) were studied on the right parietal 4 (RP4) neuron of the snail Achatina fulica Ferussac in vitro. Sodium azide altered the spontaneous action potential of RP4 neuron in a concentration-dependent manner. In lower concentrations, neither NaN(3...

Volume 29, Number 4, July/August 1997 language would, in practice, have serious unintended consequences, such as nullifying laws allowing minors to obtain confidential reproductive health care and other sensitive health services, disrupting school sex education and AIDS prevention activities, and impeding the removal of children from abusive homes. However, the outcome also appears to reflect a...

BACKGROUND AND THE PURPOSE OF THE STUDY The available literatures show that 5-HT(1A) receptors are widely distributed throughout the basal ganglia, and their activation facilitate dopamine release. Neuroleptic drugs such as haloperidol induce Parkinson-like syndrome through blocking brain D(2) receptors. This study aimed to investigate effect of buspirone, a partial agonist of 5HT(1A) receptor,...

Nan et al. [J.-X. Nan, D.-F. Li and M.-J. Zhang, A lexicographic method for matrix games with payoffs of triangular intuitionistic fuzzy numbers, International Journal of Computational Intelligence Systems 3(3) (2010) 280-289] pointed out that there is no method in the literature to find the solution of such matrix games in which payoffs are represented by triangular intuitionistic fuzzy number...

Background: Foods have been many changes from production to tables and continuous control is necessary to maintain food safety and supply foods with good quality. The aim of this study was to evaluate the quality of some foods with high consumption in Zanjan city during the 5 years from 2009 to 2013. Methods: In a case-control descriptive study with an annually control program during 5 years f...
