    Background Swimming behaviors in the forced swimming test have been reported to be depressed by stressors. Since toxic convulsion-inducing drugs related to dopamine [cocaine (COC)], benzodiazepine [methyl 6,7-dimethoxy-4-ethyl-β-carboline-carboxylate (DMCM)], γ-aminobutyric acid (GABA) [bicuculline (BIC)], and glutamate [N-methyl-D-aspartate (NMDA)] receptors can function as stressors, the present study compared their effects on the forced swimming behaviors with the effects of immobilization...

    Febrile convulsions occur relatively frequently in children, the age of onset being 6 months to 5 years. The diagnosis is based on the character of the convulsion, its frequency, length of the seizure, results of lumbar puncture and EEG. These convulsions have a good prognosis. Therapy consists in medical disruption of the convulsion and appropriate treatment of the fever.

    Full Text Available Theophylline-associated convulsions have been observed most frequently in children with fever, but the mechanism is not fully understood. In this study, we investigated the basic mechanism of aminophylline [theophylline-2-ethylenediamine]-induced convulsions and the effects of Brewer's yeast-induced pyrexia in mice. Diazepam (5-10mg/kg, i.p., a benzodiazepine receptor agonist, significantly prolonged the onset and significantly decreased the incidence of convulsions induced by aminophylline (350mg/kg, i.p.. However, the gamma aminobutyric acid (GABAA receptor agonist muscimol (1-4mg/kg, i.p., the GABAB receptor agonist baclofen (2-4mg/kg, i.p. and the N-methyl-D-aspartic acid receptor antagonist dizocilpine (0.1-0.3mg/kg, i.p. failed to protect against the convulsions. 20% Brewer's yeast (0.02ml/g, s.c. increased body temperature by 1.03, and also significantly shortened the onset and significantly increased the incidence of convulsions induced by aminophylline. The anticonvulsant action of diazepam (2.5-10mg/kg, i.p. on the convulsions induced by aminophylline was reduced by Brewer's yeast-induced pyrexia. The proconvulsant actions of the GABAA receptor antagonists picrotoxin (3-4mg/kg, i.p. and pentylenetetrazol (40-60mg/kg, i.p. were enhanced by Brewer's yeast. These results suggest that the anticonvulsant action of diazepam against aminophylline is reduced by Brewer's yeast-induced pyrexia, and that GABAA receptors are involved in the aggravation of the convulsions by Brewer's yeast in mice.

    BACKGROUND: Studies have reported that nitric oxide synthase (NOS) inhibitor can prolong the latency of hyperbaric oxygen-induced convulsion (HBOC). However, there are very few reports addressing the influence of NOS inhibitor on mental behavior.OBJECTIVE: To investigate behavioral changes after HBOC in gerbils, as well as the influence of NOS inhibitor.DESIGN, TIME AND SETTING: Randomized experiments were performed in the Laboratory of Hyperbaric Pressure and Diving Physiology, Naval Medical Research Institute of Chinese PLA (Shanghai,China) from March 2005 to June 2007.MATERIALS: Forty male gerbils were randomly divided into five groups: HBOC, saline control, NOS inhibitor, pressure control, and normal control. Each group contained eight animals.METHODS: In the HBOC group, once depression induction ended, animals were removed from the chamber five minutes after the first appearance of generalized convulsion induced by 0.5 MPa hyperbaric oxygen. Ten minutes before entering the chamber, saline control and NOS inhibitor animals were intraperitoneally injected with 1 mL saline and 20 mg/kg NG-nitro-L-arginine, respectively. The pressure control group was only exposed to 0.5 MPa. The remaining procedures in these three groups were identical to the HBOC group. The normal control group received no intervention.MAIN OUTCOME MEASURES: Open field test scores in gerbils prior to HBOC, as well as immediately,24 hours, and 72 hours after decompression ended.RESULTS: HBOC was not detected in either the normal control or the pressure control group, and there were no significant differences in opcn field test scores prior to and after HBOC (P > 0.05). HBOC occurred in the HBOC, saline control, and NOS inhibitor groups, with significant differences in open field test scores after decompression ended compared to normal control and pressure control groups (P < 0.05-0.01).Compared to the HBOC and saline control groups, the NOS inhibitor group exhibited a significantly lower score in

    Febrile convulsion is the most frequently occurring epilepsy syndrome, experienced in infants/children between 6 months and 5 years of age associated with fever >38 degrees C. Children having first or second degree relative with history of febrile convulsion, neonatal nursery stay of more than 30 days, developmental delay or attendance at day care centre are at increased risk of developing febrile convulsion. Single febrile convulsion does not increase the risk of epilepsy and there is no causal relationship between febrile convulsion and subsequent epilepsy. It has been recognised that there is significant genetic component for susceptibility to febrile seizures. To make the diagnosis of febrile convulsion, meningitis, encephalitis, serious electrolyte imbalance and other acute neurologic illnesses are to be excluded. While managing acute attack the steps to be taken are--airway management, a semi-prone position to avoid aspiration, monitoring vital signs and other supportive care. Diazepam or lorazepam is the drug to be used. There is no reason to expect phenobarbitone administered at the time of fever to be effective in prevention of febrile convulsion. The parents should be counselled about the benign nature of the convulsion. Although the febrile convulsion a frightening event, still it is a benign condition. PMID:12418634

    This study evaluated the effects of different doses of atropine and new antiepileptics, levetiracetam and topiramate, on the development of convulsions triggered by food intake in antimuscarinic-treated fasted animals. Mice deprived of food for 24 h and treated i.p. with atropine at a dose of 2.4 or 24 mg/kg developed convulsions after being allowed to eat ad libitum. No convulsions were observed in fasted animals treated with 0.24 mg/kg atropine. There was no difference in the incidence of convulsions between the two atropine treatments, but latency to convulsions was longer in 24 mg/kg atropine treated animals. The lowest dose of atropine, 0.24 mg/kg, caused stage 1 and stage 2 activity, but did not provide the convulsive endpoint (stage 3, 4, 5 activity). Administration of levetiracetam (50 or 200 mg/kg) or topiramate (50 or 100 mg/kg) to another group of 24-h fasted mice was ineffective in reducing the incidence of convulsions developed in the animals after 2.4 mg/kg atropine treatment and food intake. However, the higher dose of levetiracetam prolonged the onset of convulsions. Present results demonstrated the efficacy of low and high doses of atropine on the development of convulsions in fasted animals and provided additional evidence for the ineffectiveness of antiepileptic treatment in these seizures.

    Phenytoin (PHT) is a commonly prescribed first-line antiepileptic drug. However, long-term administration of PHT can cause memory loss and balance disturbance. Gastrodin (GD) is the major bioactive component in Tianma and has sedative, anticonvulsive, memory strengthening, and neuroprotective effects. To combine the two drugs seems attractive; however, little was known about the efficacy of combination therapy. In this study, convulsive attack was successfully induced by penicillin. Isobolographic analysis, memory and balance behavior test, histopathological examination, and Western blot analysis were used to investigate whether the combination therapy of GD and PHT can enhance anticonvulsive effect and reduce the side effects associated with PHT. The GD alone (950.60 mg/kg) and the PHT alone (45.50 mg/kg) could produce an anticonvulsive effect, while comparable effect could be produced by PHT : GD = 1 : 50 (8.59 : 429.27 mg/kg), which reduce the dose of PHT by 81% and GD by 55%. After the chronic anticonvulsive experiments of 16 days, the balance disturbance and short-/long-term memory loss were observed in the PHT group, while the PHT + GD therapy can protect the normal balance and memory function. The neuron morphology of hippocampus was preserved, and the number of surviving neurons after combination therapy was more than the model group. The amount of NF-κB (p65) expression was increased in combination group. All above suggested the potential of the combination of PHT and GD enhances the anticonvulsive effect and the neuroprotective effect and reduces the PHT-associated memory and balance disturbance. The PHT + GD strategy would provide new possibilities as a novel promising methodology to treat epileptic patients. PMID:26018871

  9. Effect of zinc protoporphyrin on carbon monoxide/heme oxygenase-1 system in rats subjected to recurrent febrile convulsion

    2007-01-01

    BACKGROUND: Studies on febrile convulsion (FC)-caused brain injury are disputed in many aspects.How FC cause nervous system injury in the developmental period and what are the characteristics of these pathological injury are unknown. The current studies have demonstrated that heme oxygenase-1 (HO-l) exerts effects on brain injury mainly by catalyzing hemoglobin to produce degradation products, and HO-1 not only has neuroprotective effects, but also has neurotoxic effects during the FC-caused brain injury. Study on the effect of zinc protoporphyrin (ZnPP) on brain injury is still in the stage of animal experiment.OBJECTIVE: To observe the effects of ZnPP on carbon monoxide (CO)/HO-1 system of rats subjected to FC, and to analyze the action pathway of ZnPP in brain protective effect.DESIGN: A randomized controlled animal experiment.SETTING: Department of Pediatrics, First Hospital Affiliated to Jiamusi University.MATERIALS: Sixty-five Wistar rats, of either gender, were involved in this study. They were randomized into normal control group( n =14, 37 ℃ water bath) and febrile treatment group (n =51, 44.5 ℃ hot water bath). Febrile treatment group was sub-divided into febrile non-convulsion group (FNC group, n =16) and FC group (n =35). FC group was further sub-divided into simple convulsion group (n =20) and ZnPP treatment group (n =15). HO-1 mRNA in situ hybridization kit was provided by Boster Bioengineering Co.,Ltd. ZnPP(dark brown powder) was the product of Jingmei Bioengineering Company.METHODS: This study was carried out in the postgraduate laboratory of Jiamusi University between January 2004 and January 2007. Rats in the febrile treatment group were placed in the 44.5 ℃ hot water bath box. If rats did not convulse in the water within 5 minutes, they were taken out, namely FNC group (n =16), and those, which were convulsed within 5 minutes, were taken out immediately when they presented such a phenomenon, namely FC group (n =35). Convulsion induction was

    Apolipoprotein E is consistently associated with the progression of some common human neurodegenerative diseases, e.g., epilepsy. We hypothesized that genetic variations in the apolipoprotein E gene have implications for susceptibility to, and prognoses in, febrile convulsion, which plays an apparent role in the development of epilepsy. We used the polymerase chain reaction and restriction enzyme digestion to characterize variations of the apolipoprotein E gene. Sixty-nine patients with febrile convulsion (simple/complex) and a corresponding cohort of healthy patients (n = 75) were used. There was no significant difference in genotypic distribution and allelic frequencies of the apolipoprotein E gene between the febrile convulsion and control groups. Comparing subpopulations of the febrile convulsion group (patients with simple and complex febrile convulsion), we noted that no patients with the epsilon3/epsilon4 genotype had complex febrile convulsions. The apolipoprotein E epsilon3/epsilon4 genotype was more frequently seen in the simple febrile than in the complicated febrile convulsion group (9 versus 0 patients, respectively). The data indicate an association with the epsilon3/epsilon4 genotype of the apolipoprotein E gene with a milder phenotype. Although apolipoprotein E4 is not a vulnerability factor regarding febrile convulsions, it seems effective in regard to prognoses. PMID:18805361

    We studied anticonvulsant effects of combined treatment with citicoline, a nootropic substance with neuroregenerative and neuroprotective activities, and valproate, an antiepileptic agent widely used in the treatment of epilepsy, on the model of pentylenetetrazole-induced (75 mg/kg, intraperitoneally) acute generalized convulsions in male Wistar rats. Combined treatment with citicoline and valproate in minimum effective doses (70 and 300 mg/kg, respectively) potentiated the anticonvulsant properties of both agents. PMID:26902360

  15. Evaluating acute effects of Electro Convulsive Therapy (ECT) on brain perfusion with Tc-99m HMPAO brain SPECT

    International Nuclear Information System (INIS)

    Regional cerebral blood flow (rCBF) was measured by Tc-99m HMPAO brain perfusion SPECT in 10 schizophrenes (8 male, 2 female) undergoing electro convulsive therapy (ECT) and the results were compared to those of baseline studies performed 3 days prior to the ECT application to evaluate its acute effect on brain perfusion. ECT caused a redistribution in the tracers uptake. There was a global increase in the rCBF and the uptake became more pronounced in the basal ganglia (left: 44.4+-1.9%, right: 43.1+-19%) and to a degree in the parietal (left: 26.5+-4.1%, right: 25+-3.4%) and temporal (left: 22.9+-4.3%, right: 22.3+-3.6%) cortices. When evaluating the effects of ECT on rCBF, factors like the used perfusion agent, the injection and rCBF measurement times, clinical status of the patient, duration of the illness, used therapeutic agents and variations in the ECT application should be taken into consideration because the obtained data may reflect either the ictal or post-ictal changes on rCBF and is specific to the group of patients undergoing the study

    1985-06-01

    A new audiogenic seizure (AGS)-susceptible strain of rats (P77PMC) was evaluated as a possible model of human febrile seizures. The long-term effects of experimental febrile seizures were observed. All 30-day-old rat pups exhibited clonic seizures during exposure to an ambient temperature of 45 +/- 0.5 degree C. The mean latency from the beginning of the hyperthermic stimulus to the onset of convulsion was 16.9 +/- 2.2 min. The rats survived this hyperthermic seizure, developed a resistance to acoustic stimulations, but were more susceptible at the age of 50 to 60 days to kainate-induced limbic seizures than controls. The results of this study imply that febrile seizures of developing P77PMC rats can change later seizure susceptibility, and there may be some correlation between febrile convulsion and temporal lobe epilepsy.

    Full Text Available Background/Aim. Despite years of research in a number of experimental models the question whether nitric oxide (NO and methylene blue (MB have pro- or anticonvulsant effects remains to be fully resolved. Methods. In adult Wistar rats the influence of a nonselective inhibitor of nitric oxide synthase NG-nitro-L-arginine methyl ester (LNAME, 10µg on clinical and biochemical effects of MB (10µg given before the intraperitoneally administered chemical convulsant pentylenetetrazole (PTZ, 80 mg/kg was examined. MB and L-NAME were applied intracerebroventricularly. PTZ application was followed by a 4- minute observation time, after which rats were sacrificed and elements of oxido-reductive balance were measured in a crude mitochondrial fraction of forebrain cortex, hippocampus and striatum. Results. Convulsive responses (forelimb dystonia - FLD, generalised clonic- and clonic-tonic convulsions - GCC and GCTC respectively were observed in all rats received PTZ, together with significantly decreased lipid peroxidation in the forebrain cortex and striatum and increased superoxide dismutase activity in the hippocampus, in comparison to controls (saline treated. It was registered anticonvulsant effects of L-NAME pretreatment. However, these effects were insignificant. In the hippocampus of these animals there was decreased lipid peroxidation (p < 0.01, p < 0.05 vs saline-treated and PTZ-treated rats, respectively and reverted PTZ-induced increase of superoxide dismutase activity. But MB individually pretreatment significantly decreased the incidence of CTCs and GCCs (FLD: p = 0.0513, prolonged the convulsive latent time for FLD, GCTCs and GCCs, in all the examined brain regions increased lipid peroxidation and decreased the level of superoxide anion. Administration of L-NAME 10 minutes before MB reverted all MB-evoked clinical and biochemical effects. Conclusion. Methylene blue applied individually before PTZ has strong anticonvulsant effects that were

    Fructose-1,6-diphosphate is a metabolic intermediate that promotes cell metabolism. We hy-pothesize that fructose-1,6-diphosphate can protect against neuronal damage induced by febrile convulsions. Hot-water bathing was used to establish a repetitive febrile convulsion model in rats aged 21 days, equivalent to 3-5 years in humans. Ninety minutes before each seizure induc-tion, rats received an intraperitoneal injection of low- or high-dose fructose-1,6-diphosphate (500 or 1,000 mg/kg, respectively). Low- and high-dose fructose-1,6-diphosphate prolonged the latency and shortened the duration of seizures. Furthermore, high-dose fructose-1,6-di-phosphate effectively reduced seizure severity. Transmission electron microscopy revealed that 24 hours after the last seizure, high-dose fructose-1,6-diphosphate reduced mitochondrial swelling, rough endoplasmic reticulum degranulation, Golgi dilation and synaptic cleft size, and increased synaptic active zone length, postsynaptic density thickness, and synaptic interface cur-vature in the hippocampal CA1 area. The present findings suggest that fructose-1,6-diphosphate is a neuroprotectant against hippocampal neuron and synapse damage induced by repeated fe-brile convulsion in immature rats.

    1985-05-01

    Folate and cobalamin parameters were studied in the serum and cerebrospinal fluid of 40 febrile paediatric patients. Eighteen of these children were in a state of febrile convulsion while the remaining 22 were non-convulsing. The serum folate concentration of all the patients was higher than that of the control group but the highest value was found in the convulsing children. There was no significant difference in the CSF folate levels between the two groups of patients. The serum cobalamin levels of the patients were significantly lower than those of the control children and the lowest mean was observed in the convulsing state. On the other hand, there was no difference in the CSF cobalamin between the convulsing and non-convulsing children. These results confirm that there is an effective blood-brain barrier system for folate even when serum folate levels are higher than normal. There is also a definite decrease in serum cobalamin during pyrexia but this decrease is more apparent in the convulsing state. The role of cobalamin metabolism in convulsion is not clear.

    Full Text Available Epilepsy is a common neurological disorder with diverse aetiology, affecting approximately 1 % of the entire population. Epilepsy present wide range of clinical manifestations, that affect the way a person feels and acts for a short time. Previous scientific investigations have indicated bufo toxin as a potential convulsant candidate that produced similar effects as other known convulsant agents. Bufo toxin has been shown to mimic or exhibit similar action as other known convulsant agent. Its biochemical components are formed as a result of the binding of bufo-fagin and a molecule arginina. There exist wide array of convulsant agents used in the screening of anti-convulsant agents. The commonly used one are: bicuculline, picrotoxin, pentylene tetrazole, isonizid etc. However, these agents are expensive, not easily available and affordable. This challenge prompted the search of other alternative convulsant agents that is easily accessible for use in the screening of anti-convulsant agents. The principal objective of this review paper is to suggest the possible use of bufo toxin which mimics the action of existing convulsant agents. This new testing convulsant agent (bufo toxin is inexpensive, affordable and easy to use when compared to other known convulsant agents. The experimental procedure is easy and it gives a broad spectrum in comparing the action of bufo toxin to other chemical convulsant agents. It also offers researchers broader view or options in exploring the anti-convulsant activity of test agents and the understanding of their possible mechanism of action.

  2. Convulsant bicuculline modifies CNS muscarinic receptor affinity

    2006-04-01

    Full Text Available Abstract Background Previous work from this laboratory has shown that the administration of the convulsant drug 3-mercaptopropionic acid (MP, a GAD inhibitor, modifies not only GABA synthesis but also binding of the antagonist [3H]-quinuclidinyl benzilate ([3H]-QNB to central muscarinic receptors, an effect due to an increase in affinity without modifications in binding site number. The cholinergic system has been implicated in several experimental epilepsy models and the ability of acetylcholine to regulate neuronal excitability in the neocortex is well known. To study the potential relationship between GABAergic and cholinergic systems with seizure activity, we analyzed the muscarinic receptor after inducing seizure by bicuculline (BIC, known to antagonize the GABA-A postsynaptic receptor subtype. Results We analyzed binding of muscarinic antagonist [3H]-QNB to rat CNS membranes after i.p. administration of BIC at subconvulsant (1.0 mg/kg and convulsant (7.5 mg/kg doses. Subconvulsant BIC dose failed to develop seizures but produced binding alteration in the cerebellum and hippocampus with roughly 40% increase and 10% decrease, respectively. After convulsant BIC dose, which invariably led to generalized tonic-clonic seizures, binding increased 36% and 15% to cerebellar and striatal membranes respectively, but decreased 12% to hippocampal membranes. Kd value was accordingly modified: with the subconvulsant dose it decreased 27% in cerebellum whereas it increased 61% in hippocampus; with the convulsant dose, Kd value decreased 33% in cerebellum but increased 85% in hippocampus. No change in receptor number site was found, and Hill number was invariably close to unity. Conclusion Results indicate dissimilar central nervous system area susceptibility of muscarinic receptor to BIC. Ligand binding was modified not only by a convulsant BIC dose but also by a subconvulsant dose, indicating that changes are not attributable to the seizure process

    Full Text Available Abstract Background It is known that following chronic dosing with bupropion HCl active metabolites are present in plasma at levels that are several times higher than that of the parent drug, but the possible convulsive effects of the major metabolites are not known. Methods We investigated the convulsive liability and dose-response of the three major bupropion metabolites following intraperitoneal administration of single doses in female Swiss albino mice, namely erythrohydrobupropion HCl, threohydrobupropion HCl, and hydroxybupropion HCl. We compared these to bupropion HCl. The actual doses of the metabolites administered to mice (n = 120; 10 per dose group were equimolar equivalents of bupropion HCl 25, 50 and 75 mg/kg. Post treatment, all animals were observed continuously for 2 h during which the number, time of onset, duration and intensity of convulsions were recorded. The primary outcome variable was the percentage of mice in each group who had a convulsion at each dose. Other outcome measures were the time to onset of convulsions, mean convulsions per mouse, and the duration and intensity of convulsions. Results All metabolites were associated with a greater percentage of seizures compared to bupropion, but the percentage of convulsions differed between metabolites. Hydroxybupropion HCl treatment induced the largest percentage of convulsing mice (100% at both 50 and 75 mg/kg followed by threohydrobupropion HCl (50% and 100%, and then erythrohydrobupropion HCl (10% and 90%, compared to bupropion HCl (0% and 10%. Probit analysis also revealed the dose-response curves were significantly different (p 50 values of 35, 50, 61 and 82 mg/kg, respectively for the four different treatments. Cox proportional hazards model results showed that bupropion HCl, erythrohydrobupropion HCl, and threohydrobupropion HCl were significantly less likely to induce convulsions within the 2-h post treatment observation period compared to hydroxybupropion HCl.

    All excitatory amino acid antagonists studied: diethyl esters of aspartic (DEEA) and glutamic (DEEG) acids, 2-amino-3-phosphono-propionic acid (APPA) and 2-amino-4-phosphono-butanoic acid (APBA), diminished the amplitude of excitatory postsynaptic potentials (EPP) of the locust (Locusta migratoria migratorioides) muscle fibers and arbitrary blocked glutamate (GLU) and aspartate (ASP) responses. Kynurenine (KYN) and quinolinic (QUI) acid had no effect on EPP even at a concentration of 2 X 10(-2) M. The antagonists were not strictly selective against intracerebroventricularly administered endogenous convulsants: GLU, ASP, KYN and QUI and in simulation of experimental seizures in mice. The antagonists structurally similar to ASP prevented ASP- and KYN-induced seizures in lower doses than GLU derivatives. Anti-KYN, but not anti-QUI DEEA, DEEG, APPA and APBA efficacy suggests that KYN and QUI act on different structures or binding sites. PMID:2869799

    A novel bromide salt of the antidepressant bupropion (bupropion HBr) has recently been developed and approved for use in the United States. Given previous use of bromides to treat seizures, and that the existing chloride salt of bupropion (HCl) can cause seizures, it is important to determine if the HBr salt may be less likely to cause seizures than the HCl salt. In the present animal studies this was evaluated by means of quantified electroencephalogram (EEG), observation, and the rotarod te...

  12. Comparisons of drug efficacy and time-effect among magnesium valproate,sustained-release magnesium valproate tablet and depakine chrono for epilepsy An experiment of determining cortical convulsive threshold in rats undergoing electrical stimulation

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    BACKGROUND:Scholars have investigated the differences in drug metabolism and pharmacodynamics between valproate and its sustained-release tablets only from the angle of pharmaceutical sciences or clinical practice.Whether the fact that differences in drug efficacy and time-effect of different doses of valproate and different types of sustained-release valproate tablets at the same concentration can be quantitatively reflected by determining the changes in convulsive threshold pre- and post-administration in rat models of determining the convulsive threshold developed by direct cortical electrical stimulation remains unclear.OBJECTIVE:This study aimed to compare the drug efficacy and time-effect among magnesium valproate,sustained-release magnesium valproate tablet and depakine chrono in the treatment of epilepsy by determining the convulsive threshold of rat models created by direct cortical electrical stimulation,and human serum drug concentration before and after administration.DESIGN:A controlled observational experiment.SETTING:Research Institute of Epilepsy,Shanxi Medical University.MATERIALS:Adult health male SD rats of clean grade,weighing 200 - 220 g,provided by the Laboratory Animal Center of Shanxi Medical University.The protocol was carried out in accordance with requests from Animal Ethics Committees for guidance.Magnesium valproate (Lot No.041004) and sustained-release magnesium valproate tablet (Lot No.050501) were produced in Hunan Xiangzhong Pharmaceutical Co.,Ltd.METHODS:This study was carried out in the Laboratory for Epilepsy,Shanxi Medical University between June and August 2005.①All the SD rats were created into models for determining cortical convulsive threshold.They were randomly divided into 4 groups with 20 rats in each:magnesium valproate tablet group,sustained-release magnesium valproate tablet group,depakine chrono group and control group.After being modeled,the rats in the first 3 groups were intragastrically administrated with

    Convulsive status epilepticus (CSE) is a major medical emergency associated with a 50 % morbidity rate. CSE guidelines have recommended prompt management for many years, but there is no evidence to date that they have significantly improved practices or outcomes. Developing neuroprotective strategies for use after CSE holds promise for diminishing morbidity and mortality rates. Hypothermia has been shown to afford neuroprotection in various health conditions. We therefore designed a trial to determine whether 90-day outcomes in mechanically ventilated patients with CSE requiring management in the intensive care unit (ICU) are improved by early therapeutic hypothermia (32-34 °C) for 24 h with propofol sedation. We are conducting a multicentre, open-label, parallel-group, randomised, controlled trial (HYBERNATUS) of potential neuroprotective effects of therapeutic hypothermia and routine propofol sedation started within 8 h after CSE onset in ICU patients requiring mechanical ventilation. Included patients are allocated to receive therapeutic hypothermia (32-34 °C) plus standard care or standard care alone. We plan to enrol 270 patients in 11 ICUs. An interim analysis is scheduled after the inclusion of 135 patients. The main study objective is to evaluate the effectiveness of therapeutic hypothermia (32-34 °C) for 24 h in diminishing 90-day morbidity and mortality (defined as a Glasgow Outcome Scale score <5). The HYBERNATUS trial is expected to a decreased proportion of patients with a Glasgow Outcome Scale score lower than 5 after CSE requiring ICU admission and mechanical ventilation.

    The causes of febrile convulsions are usually benign. Such convulsions are common in children and their long-term consequences are rare. However, other causes of seizures, such as intracranial infections, must be excluded before diagnosis, especially in infants and younger children. Diagnosis is based mainly on history taking, and further investigations into the condition are not generally needed in fully immunised children presenting with simple febrile convulsions. Treatment involves symptom control and treating the cause of the fever. Nevertheless, febrile convulsions in children can be distressing for parents, who should be supported and kept informed by experienced emergency department (ED) nurses. This article discusses the aetiology, clinical presentation, diagnosis and management of children with febrile convulsion, and best practice for care in EDs. It also includes a reflective case study to highlight the challenges faced by healthcare professionals who manage children who present with febrile convulsion. PMID:25952398

    Serotonin (5-HT) is thought to play an important role in the seizures of El mice because the seizure threshold of El mice correlates with the 5-HT concentration in the central nervous system. In this study, the anticonvulsant effect of a 5-HT reuptake blocker, citalopram, was evaluated behaviorally and biochemically. El mouse convulsions were inhibited by chronic administration of citalopram (80 mg/kg/day, p.o. for 2 weeks), but were not inhibited by acute administration of citalopram (80 mg/...

    Non-convulsive status epilepticus is an insidious condition and a challenging diagnosis for neurologists on call. The condition must, however, be recognized, since it constitutes a neurological emergency. Non-convulsive status epilepticus may also be associated as an additional complication with an acute neurologic disease, in which case an EEG recording is usually required. In addition, non-convulsive status epilepticus can be found in a significant proportion of patients with unconsciousness of unknown origin. PMID:21995129

    Febrile convulsions are generally thought to be induced by metabolic changes during the rise-phase of body temperature. The mechanism by which convulsions are induced, however, is not fully elucidated. In this article, we propose a new hypothesis about the induction mechanism of febrile convulsions that takes into account the hypozincemia during fever. This hypozincemia activates the NMDA receptor, one of the glutamate family of receptors, which may play an important role in the induction of epileptic discharge. PMID:2190072

    Full Text Available The present investigation was aimed to study an anticonvulsant activity of aqueous extract of Desmodium triflorum (L. DC., Fabaceae, in mice. Animal models of epilepsy namely the pentylenetetrazole, and maximal electroshock induced convulsion were used to evaluate the anticonvulsant effects of the extracts. The biochemical estimation was done by measuring the lipid peroxidation and reduced glutathione. In the pentylenetetrazole induced convulsion, aqueous extract of D. triflorum 800 mg/kg significant delayed the onset of convulsion, reduced the duration of convulsion (p<0.05 and reduced mortality. The aqueous extract of D. triflorum 800 mg/kg dose reduced hind limb tonic extension phase of maximal electroshock induced convulsion induced convulsion in mice (p<0.05. The pretreated aqueous extract of D. triflorum showed significant inhibition of lipid peroxidation and increases the reduced glutathione level in mice brain tissue (p<0.001. The results revealed that D. triflorum possesses a significant dose dependent anticonvulsant activity.

  20. Lower degree of fever at the initial febrile convulsion is associated with increased risk of subsequent convulsions.

    El-Radhi, A S

    1998-01-01

    We studied 132 children admitted consecutively with their first febrile convulsion to assess whether the degree of fever at the onset of the convulsion can predict the risk of subsequent convulsions. The children studied were reviewed at least 2 years after the initial febrile convulsion to determine the number of children who had recurrences of febrile convulsions and/or afebrile convulsions. Children with body temperatures below 39 degrees C at the onset of their initial febrile convulsion (Group 1) were two and half times more likely to experience multiple convulsions within the same illness than those with body temperatures above 39 degrees C (Group 2). This occurred when the body temperature rose above that which had triggered the initial febrile convulsion. Children in Group 1 were also over three times more likely to experience recurrent febrile convulsion in subsequent illnesses than those in Group 2. As for subsequent development of afebrile convulsion or epilepsy, although the risk was low, it only occurred in Group 1. It is suggested that the known association between multiple convulsions, recurrent febrile convulsions and epilepsy may be due to the single predisposing factor of a low degree of fever at the onset of febrile convulsion. Each child with febrile convulsion may have his own threshold for eliciting a convulsion with fever; the lower this threshold is, the more likely are subsequent convulsions. PMID:10724102

    2002-11-15

    We aimed to investigate the possible convulsant action of arginine vasopressin (AVP) in both a febrile convulsion model in rat pups and a temporal lobe epilepsy model in adult rats and to define the receptor type which mediates this effect. In rat pups, 125 ng V2 receptor antagonist significantly prevented hyperthermic seizures, but did not affect seizure latency. In adult rats, the only effective dose and agent was 125 ng V2 receptor antagonist, which prevented pilocarpine-induced status epilepticus, extended the status epilepticus latency and improved the 24 h survival rate. These data suggest that AVP has a convulsant activity in febrile convulsions and also in seizures independent of fever, and this effect is mediated by V2 receptors. PMID:12438923

    Since Acyclovir is available a sufficient treatment of herpes simplex virus (HSV) encephalitis exists. Febrile convulsions may occur as the initial manifestation of an encephalitis, particularly of an HSV encephalitis. Within 25 months out of 151 children with febrile convulsions five children with complicated febrile convulsions were admitted at the pediatric department of Graz. In all children HSV antibodies in serum and cerebrospinal fluid (CSF) were negative and the diagnosis of an HSV encephalitis was made by positive CSF HSV polymerase chain reaction (PCR). Therefore, in any suspected case, i.e. in any case of a complicated febrile convulsion, CSF should be investigated including a HSV PCR to rapidly confirm or exclude HSV encephalitis. PMID:8386831

    Febrile convulsion is the most common disorder in childhood with good prognosis. There are different hypotheses about neurotransmitters and trace element changes in biological fluids which can have a role in pathogenesis of febrile convulsion. In this study, serum selenium, zinc, and copper were measured by atomic absorption spectrometry in the children with febrile convulsion (n = 30) and in the control group (n = 30). The age and sex of the subjects were registered. Selenium and zinc were found to be significantly lower in febrile convulsion cases than in the control group (p < 0.0001 and p < 0.0001, respectively). There was no significant difference in the value of copper between the two groups (p = 0.16). While selenium and zinc levels were 44.92 +/- 10.93 microg/l and 66.13 +/- 18.97 microg/dl in febrile convulsion, they were found to be 62.98 +/- 9.80 microg/l and 107.87 +/- 28.79 microg/dl in healthy children. Meanwhile, copper levels were 146.40 +/- 23.51 microg/dl in the patients and 137.63 +/- 24.19 microg/dl in the control group, respectively. This study shows that selenium and zinc play an important role in the pathogenesis of febrile convulsion. PMID:19669113

    In this study, 140 children aged from 6 months to 6 years who presented with a first febrile convulsion at the King Fahad Hofuf Hospital, Al-Hassa, Saudi Arabia were retrospectively identified. Information about these children was obtained from their medical records covering a follow-up period of 3 years from July 1989 to June 1992. Recurrent febrile convulsions occurred in 60 of them (43%). Relevant risk factors that were observed to be significantly associated with seizure recurrence included an age of less than 18 months (odds ratio [OR] = 3.82; 95% confidence interval [CI] = 9.26, 1.58), an initial febrile convulsion that was complex (OR = 4.41; CI = 9.50, 2.05) and a positive family history of febrile convulsions (OR = 4.12; CI = 10.74; 1.58), while a decreased risk of recurrence occurred with a temperature of over 39 degrees C (OR = 4.60; CI = 9.44; 2.24). There was no association between seizure recurrence and the duration of the initial febrile convulsion (OR = 0.93; CI = 2.33; -2.04) or family history of epilepsy (OR = 0.88; CI = 4.22, -3.27). An important observation in the present study is the close association (ORM-H = 2.36; X2M-H = 9.65) between the development of an afebrile convulsion and seizure recurrence among the group of children with CFC. Anticonvulsant prophylaxis should therefore be considered for children whose initial febrile convulsions are complex in nature. PMID:7880092

    The 6-year incidence rates of febrile convulsions in all 3-year-old children in Fuchu (covering 95% of children, number examined 17,044) was 8.2%. The incidence was higher in boys than in girls (9.0%: 7.5%, P less than 0.001). The incidence rates varied with the month and year of birth, but the variations observed were slight. Two peak appearances of seasonal variation of the first febrile convulsion were found in November-January and in June-August. The former could be interpreted as a tendency to winter virus infection of the upper respiratory tract in children. The other peak in summer could be explained as a tendency to gastrointestinal infection. Liability to febrile convulsion was influenced by the age of children and by the seasonal variations of febrile illness, but not by the season of birth. PMID:6464667

    In 108 children admitted to the Maternity and Children's Hospital, Riyadh with their first febrile convulsion, clinical course, management and underlying causes were analysed. There was a preponderance of boys (69%) and a mean age of 18.6 months with a peak incidence (82%) between six months and three years. The commonest precipitating conditions were upper respiratory infection and gastroenteritis. Physical findings were confined to those of the primary disease. Routine investigations, including CSF analysis were not helpful. Convulsions were mainly of the simple type, single and symmetrical, and did not last for more than 30 minutes. Two thirds of the children reached hospital within two hours of the onset of their first convulsion, and the remainder up to ten hours after the convulsion had ceased. In only 18 patients did the parents take measures to lower the temperature or revive the child. Management of febrile convulsions is discussed. Since the condition is common and, if repeated, may have serious effects, methods of educating parents are suggested. PMID:6191623

    Febrile convulsion is characterised by convulsion associated with fever in an infant or child aged between six months and six years. The febrile illness causing the convulsion should not be secondary to an intracranial infection (meningitis or encephalitis) or acute electrolyte imbalance. Most cases of febrile convulsion are short lived and self-terminating. However, a few cases of prolonged febrile convulsion may need anticonvulsant medication to stop the seizure. Management is mainly symptomatic, although anticonvulsants may have a role in a small number of children with complex or recurrent febrile convulsion. Referral to paediatric neurologists may be necessary in cases of complex or recurrent febrile convulsion, or in those where a pre-existing neurological disorder exists. One third of children will develop a further febrile convulsion during subsequent febrile illness. Nurses have a vital role in managing children with febrile convulsion, educating parents about the condition and dispelling myths. This article outlines the presentation, management, investigations and prognosis for febrile convulsion, indicating how nurses working in different clinical areas can help to manage this common childhood condition.

    A descriptive study was carried out on patients admitted for febrile convulsion over a two-year period to determine rate of lumbar puncture (LP) refusal, factors associated with LP refusal and outcome of such patients. From 77 patients indicated and requested for LP, 19 (25%) patients refused the procedure. Refusal of LP was significantly more common among the Malay ethnic group (p = 0.01) but not significantly associated with age,gender or whether the patient was admitted for a first or recurrent febrile convulsion. Half of the patients who refused LP had to be started empirically on antibiotics for meningitis. Patients who refused LP were also 8.5 times more likely to discharge themselves "at own risk" (AOR), compared to other patients with febrile convulsion (p = 0.004). In conclusion, LP refusal is a common problem in the local setting and is a hindrance to the proper management of patients with fever and seizure. Appropriate measures must be carried out to educate the public, particularly those from the Malay ethnic group on the safety and usefulness of the procedure. Reasons for patients discharging AOR following LP refusal also need to be addressed and problems rectified. PMID:11281439

    Is a routine lumbar puncture in patients with first episode of febrile convulsion necessary? In order to find an answer to this question, in a prospective study 332 children with a first episode of convulsion were lumbar punctured. 17 patients (5.1%) had abnormal CSF findings although clinically meningitis was not suspected in them. This makes a lumber puncture in children with the first episode of febrile convulsion unavoidable.

  7. Soman-induced convulsions: The neuropathology revisited

    International Nuclear Information System (INIS)

    The organophosphorus compound soman, an irreversible inhibitor of cholinesterases, produces seizure activity and related brain damage. Studies using various biochemical markers of programmed cell death (PCD) suggested that soman-induced cell damage in the brain was apoptotic rather than necrotic. However, it has recently become clear that not all PCD is apoptotic, and the unequivocal demonstration of apoptosis requires ultrastructural examination. Therefore, the present study was undertaken to reinvestigate the damage produced in the brains of mice sacrificed at various times within the first 24 h or at 7 days after a convulsive dose of soman. Classical histology and ultrastructural examination were performed. The immunohistochemical expression of proteins (p53, Bax) involved in PCD, DNA fragmentation (TUNEL method at light and electron microscopy levels) and the glial reaction were also explored. Our study confirms that the severity of lesions depended on the duration of convulsions and shows that cerebral changes were still occurring as late as 7 days after the onset of long-lasting convulsions. Our observations also establish that there was a large variety of ultrastructurally distinct types of cell damage, including hybrid forms between apoptosis and necrosis, but that pure apoptosis was very rare. A prominent expression of p53 and Bax proteins was detected indicating that PCD mechanisms were certainly involved in the morphologically diverse forms of cell death. Since purely apoptotic cells were very rare, these protein expressions were presumably involved either in nonapoptotic cell death mechanisms or in apoptotic mechanisms occurring in parallel with nonapoptotic ones. Moreover, evidence for DNA fragmentation by the TUNEL method was found in apoptotic but also in numerous other morphotypes of cell damage. Therefore, TUNEL-positivity and the expression of PCD-related proteins, in the absence of ultrastructural confirmation, were here shown not to provide

    In this study, we aimed to analyze features and outcome of convulsion in pediatric lupus nephritis patients. We retrospectively reviewed data of 14 Iranian children with lupus nephritis who developed seizures and compared them with a group of the same number of well matched pediatric lupus nephritis patients. Higher serum creatinine levels and higher frequencies of anemia and lymphopenia were observed in the convulsion group. Multivariable logistic regression analysis revealed that the only risk factor for development of convulsion in pediatric lupus patients with nephritis was lymphopenia. Survival analysis showed that convulsion had no impact on patient and renal function outcomes in our pediatric lupus nephritis subjects. In conclusion, we found that lymphopenia is a predictive factor for convulsion occurrence in our patients and special attention to neurological status assessment may be needed in this situation.

    The clinical characteristics of 303 patients who had episodes of feverish convulsions (FC) were retrospectively reviewed. No preference was seen for either sex (1.3/1). In 75.3% of the cases, the convulsions occurred in children under two. There was some predominance of tonic-clonic crisis and generalized clonic-tonic convulsions (85.5%) with 21.8% of complex partial crisis. In 44.8% of the cases a perinatal history of high risk was noted. A comparative investigation was carried out in a subgroup of 244 children in who FC vs non-febrile convulsions (NFC) were during two years. In 35.2% of the patients neurological abnormalities were found associated, among them were language difficulties (27.4%) and psychomotor retardation (11.9%). In 36.4% of the cases, the EEG was found to be abnormal, and paroxysmal in 27%. The predominating perinatal pathological complications were perinatal hypoxia-anoxia and prematurity. In 84% of the patients, anti-convulsive medication was administered. Of the 244 patients, 62 (25.4) of them had NFC which were directly related to the number of risk factors and their characteristics. Among those risk factors were partial convulsions, neurological deficit, abnormal EEG, convulsions lasting over 10 minutes and a previous family history of epilepsy. It is noteworthy that 15.7% of the patients had no risk factors related to epilepsy. In those patients who suffered from convulsions from an early age, who had convulsions of a partial--complex type, which lasted over 20 minutes and repeated frequently--were seen to be the most likely to develop epilepsy. The medications prescribed prevented the occurrence of the FC but did not significantly diminish the development of epilepsy. Febrile convulsions; epilepsy; perinatal. PMID:1692466

    Febrile convulsion is common in young children and occurs in 3-4% of children aged under six years of age. This is the most common seizure disorder and it is not epilepsy. It occurs generally with high temperatures and recurs in one third of children during a subsequent febrile illness. These episodes can be extremely frightening for parents and lot of reassurance needs to be provided by health professionals after an episode. Most often the episodes are short lived and self-terminating and long-term anticonvulsant medicines are not required. The prognosis is generally good and affected children do not suffer any long-term health problems. Community practitioners can provide education, support and counselling to help families return to normality after an event. PMID:22866531

  14. Regional changes in brain 2-14C-deoxyglucose uptake induced by convulsant and non-convulsant doses of lindane

    International Nuclear Information System (INIS)

    Lindane-induced dose- and time-related changes in regional 2-14C-deoxyglucose (2-DG) uptake were examined in 59 discrete rat brain structures using the 2-DG autoradiographic technique. At different times (0.5-144 hr) after administration of a seizure-inducing single dose of lindane (60 mg/kg), 2-DG uptake was significantly increased in 18 cortical and subcortical regions mainly related to the limbic system (e.g., Ammon's horn, dentate gyrus, septal nuclei, nucleus accumbens, olfactory cortex) and extrapyramidal and sensory-motor areas (e.g., cerebellar cortex, red nucleus, medial vestibular nucleus). There was also a significant increase in superior colliculus layer II. In addition, significant decreases occurred in a group of 6 regions (e.g., auditory and motor cortices). Non-convulsing animals treated with the same dose of lindane showed a regional pattern of 2-DG uptake less modified than the convulsant group. A non-convulsant single dose of lindane (30 mg/kg) also modified significantly the 2-DG uptake (0.5-24 hr) in some brain areas. Although the various single doses of lindane tested produced different altered patterns of brain 2-DG uptake, some structures showed a similar trend in their modification (e.g., superior colliculi and accumbens, raphe and red nuclei). Repeated non-convulsant doses of lindane produced defined and long-lasting significant elevations of 2-DG uptake in some subcortical structures. Considering the treated groups all together, 2-DG uptake increased significantly in 26 of the 59 regions examined but only decreased significantly in 9 of them during the course of lindane effects. This fact can be related to the stimulant action described for this neurotoxic agent. The observed pattern provides a descriptive approach to the functional alterations occurring in vivo during the course of lindane intoxication

    Full Text Available Purpose : The association between iron deficiency anemia and febrile convulsion in infants has been examined in several studies with conflicting results. Therefore, the authors aimed to evaluate the precise relationship involved. Methods : In this case-control study, the authors assessed 100 children with a diagnosis of febrile convulsion, aged between 9 months and 2 years, during January 2007 to July 2009. The control group consisted of 100 febrile children without convulsion; controls were closely matched to the cases by age, gender, and underlying disease. Results : The mean ages of the febrile convulsion and control group were 16.3¡?#?.4 ;and 15.8¡?#?.1 ;months, respectively, and the two groups had no differences in clinical features. Iron deficiency anemia (Hb &lt;10.5 gm/dL was more frequent in the febrile convulsion group than in the control group, although there was no statistical significance. Unexpectably, the RDW (red blood cell distribution width was significantly lower and the MCNC (mean corpuscular hemoglobin concentration was significantly higher among seizure cases than among the controls (P&lt;0.05. There is no statistical difference between simple and complex febrile groups in the clinical and laboratory profiles. On multiple logistic regression analysis, iron deficiency anemia was more frequent, but the RDW was lower, among the cases with febrile convulsion, compared with the controls. Conclusions : Our study suggests that the iron deficiency anemia is associated with febrile convulsion, and screening for iron deficiency anemia should be considered in children with febrile convulsions.

    131 consecutive admissions to hospital for a first febrile convulsion were studied to find which factors predisposed to a complicated fit--defined as one lasting more than 30 minutes, unilateral, or repeated within the same illness. A significant excess of complicated attacks occurred where the age of onset was less than 16 months, where both family history of convulsive disorder and perinatal abnormality were present, and, in females only, where it was suspected that neurological disorder preceded the first fit.

    2003-01-01

    Full Text Available Controversy about proconvulsant and anticonvulsant nitric oxide (NO effects and the place of oxidative stress in convulsions, are still a matter of research. We investigated the interaction between 2-amino-5-phosphonovaleric acid (APV, a competitive N-methyl-D-aspartate (NMDA receptor antagonist and Nw-nitro-L-arginine methyl ester (L-NAME, a nonselective nitric oxide synthase (NOS antagonist, in pentylenetetrazole (PTZ-induced convulsions. Pentylenetetrazole was applied to adult Wistar rats intraperitoneally (ip in a single dose of 80 mg/kg, and L-NAME (10 µg/10 µl or APV (20 µg/10 µl intracerebroventricularly (icv, 30 and 10 minutes before PTZ, respectively. In the same manner, another group received both antagonists. Control animals were given 0.9% saline. Nw-nitro-L-arginine methyl ester exerted a weak anticonvulsant effect, preventing generalized clonic (GCC and clonic-tonic convulsions (CTC in 17% of cases. With APV protection against GCC and CTC was 100%, forelimb dystonia (FLD was decreased in 33% of cases, and time to onset of all convulsive patterns was prolonged (p<0.05 to 0.01. All effects of APV, except in CTC, were reversed by L-NAME applied prior to APV. In APV-PTZ treated animals, superoxide anion content was increased in the forebrain cortex, striatum and hippocampus, without an overwhelmed antioxidative superoxide dismutase (SOD defense system in the other treatments. When the APV-PTZ group was treated with L-NAME, both SOD activity and superoxide anion content were additionally decreased indicating that the NOS-NO system was involved in the metabolism of superoxide anions. It is suggested that clinical and biochemical effects of NO strongly depend upon the pretreatment and might lead to a wrong impression of NO contradictory activity.

    The effect on behavior of eight anticholinergic agents: atropine, scopolamine, trihexyphenidyl, biperiden, homatropine, eucatropine, hexocyclium and propantheline, injected into the cerebral ventricle (ICV) of the cat was investigated and compared. The anticholinergic agents evoked: (1) psychomotor stimulation such as miaowing, loud calling, restlessness, impelling locomotion, jumping, vacant staring, apprehension and loss of interest of the surroundings; (2) aggression, hissing, threat, attack, defense, fighting with paws and flight; (3) autonomic responses including mydriasis, tachypnea, dyspnea, licking, vomiting, salivation, micturition and defection; and (4) motor phenomena comprising scratching, ataxia, rigidity, tremor, weakness with adynamia or myoclonic jerks. Convulsions appeared only after ICV injections of atropine and homatropine. The most characteristic behavioral effect of anticholinergic agents was psychomotor stimulation accompanied by mild aggressive responses. The only exception was propantheline which caused a muscular weakness and adynamia. Atropine and scopolamine alone induced a dose-dependent impelling locomotion as well as fighting behavior. Carbachol and eserine injected intracerebroventricularly reversed the locomotion autonomic and motor phenomena produced by anticholinergic agents administered similarly. It is suggested that anticholinergic agents acting as partial agonists, can produce their behavioral effects through central cholinoceptive sites. PMID:3703893

    This study aimed to examine the close correlation between complicated febrile convulsions (CFC) and medial temporal lobe epilepsy and to delineate characteristics of temporal lobe epilepsy with CFC. Patients with temporal lobe epilepsy were divided into those with a prior episode of CFC (n=52), those with febrile convulsions other than CFC, and those without either (n=345). Clinical constellations, neuroimaging, drug resistance, and effects of temporal lobectomy of the three groups were compared. A close association between CFC and temporal lobe epilepsy was confirmed. The salient features of temporal lobe epilepsy with CFC were early age at onset of habitual seizures (about 10 years), the predominance of autonomic auras, and a high incidence of MRI evidence of unilateral medial temporal sclerosis. Patients with temporal lobe epilepsy with prior CFC had an excellent outcome after surgery, by contrast with an unfavourable response to drug therapy. The surgical results were discouraging in patients with temporal lobe epilepsy without history of any febrile convulsions and without solid brain tumours. These results indicate surgical intervention as the choice of therapy in a substantial number of patients with temporal lobe epilepsy with a history of CFC. PMID:9489540

    Full Text Available Background: Febrile seizures are the most common convulsion disorder in childhood. The possible risk of developing epilepsy in febrile seizures is about 2-10%. EEG is helpful to diagnose epilepsy; however, there are controversies about the abnormal EEG and associated risk factors .The aim of this study was to determine EEG abnormality and effective risk factors in patients with complex febrile seizures. Methods: This study was conducted on the patients with complex febrile seizures in 2009-2010.EEG was performed on all children 6 to 10 days after seizure and reported by a neurologist. Demographic data and risk factors, including age, sex, family history of epilepsy and febrile convulsions, presentation of seizure, postictal neurological disorder were documented by a checklist and their association with EEG was analyzed. Results: 111 patients with complex febrile seizure, 70 girls and 41 boys, with the mean age of 3.4±20 months were studied. EEG was abnormal in 37.8% of patients, 9% were epileptic form abnormality and 28.8% were nonspecific abnormal. There was a statistically significant association between EEG abnormality in patients with focal seizures, family history of febrile seizures and postictal neurologic disorder (p<0.05. Conclusion: The results of this study showed abnormality of EEG in complex febrile convulsions in 37.8% of patients, which was significantly higher in patients with postictal neurological disorder, focal seizures and family history of febrile seizure.

    Convulsive status epilepticus is a relatively common life-threatening illness requiring prompt intervention. There has been much debate about the appropriate protocol for management of convulsive status epilepticus. Published data on the management of this condition in Ireland is limited. Our aim was to establish if there was a structured, evidence-based or consensus-based protocol being implemented in the management of status epilepticus in our centre. We retrospectively audited all charts with a diagnosis of \\'Status Epilepticus\\' admitted to our hospital from January 1998 to December 2002. A total of 95 episodes of convulsive status epilepticus were recorded. 34 charts were reviewed. Benzodiazepines were the drug class of first choice in 96% of patients. However, the doses of benzodiazepines used varied widely. The most frequent dose of phenytoin used was 1 gram. No one received continuous EEG monitoring during treatment of refractory status epilepticus. Overall mortality was 18%. The results of this study show that there is no consistent protocol was being followed for the management of convulsive status epilepticus in our centre. The drugs of first choice varied between diazepam and lorazepam in most cases. Although phenytoin was used as second line drug, the dose used was frequently suboptimal. We have developed a protocol for the management for convulsive status in our centre.

    Full Text Available Cases of benign infantile convulsions with mild gastroenteritis (BICE treated in our hospital from 2008 to 2012 were analyzed retrospectively. Among the 65 cases of convulsions with acute diarrhea, there were 18 cases of BICE, 15 cases of febrile seizures, 13 cases of epilepsy, 6 cases of viral encephalitis, 6 cases of hyponatremia encephalopathy, 3 cases of hypernatremia encephalopathy, 2 cases of toxic encephalopathy, and 2 cases of hypocalcemia convulsion. The convulsion occurred mostly during the first 2 d of the illness and was in a generalized tonic or tonic-clonic form. Positive rotavirus antigens in the BICE patients were detected in 83.33% (15/18. Phenobarbital was administered after the first convulsion (5-10 mg/kg, and diazepam was given intravenously in case of recurrence (0.10-0.30 mg/kg. BICE occurs frequently in infantile and controlling relapse is the main purpose. The prognosis is good. doi: 10.3969/j.issn.1672-6731.2014.03.019

    Full Text Available INTRODUCTION Delta sleep inducing peptide (DSIP is well known natural somnogenic peptide that has many other physiological functions. DSIP analogues representing hepta-and octapeptides (also known as long as well as tetrapeptide (termed short, used in our experiments were synthesized with a view to evaluate the peptide specificity in sleep. The effects of DSIP and its analogue DSIP1-4 on metaphit 1-[1(3-isothiocyanatophenyl-ciclohexyl-piperidine] induced audiogenic seizures were evaluated in rats. METHODS Male Wistar albino rats were divided into 4 groups: 1. Saline; 2. Metaphit; 3. Metaphit + DSIP, and 4. Metaphit + DSIP1-4. To examine the blocking effects of DSIP and its analogue on fully developed metaphit seizures, the last two groups were injected after the 8th audiogenic testing. Animals were injected with metaphit (10 mg/kg intraperitoneally (i.p. and exposed to sound stimulation (100±3 dB, 60 s at hourly intervals. The incidence and severity (running, clonus and tonus of seizures were analyzed. For electroencephalographic (EEG recordings, three gold-plated electrodes were used. Convulsive behavior was assessed by incidence of motor seizure and by seizure severity grade, determined by descriptive rating scale ranging from 0 to 3:0- no response, 1 -wild running only; 2-wild running followed by clonic seizures of all four limbs with body rollover; 3 - wild running progressing to generalized clonic convulsions followed by tonic extension of fore-and hind legs and tail. Sound onset, seizure events, and sound offset, along with the animal's behavior (convulsive or other were characterized with EEG changes. RESULTS In most animals, the administration of metaphit resulted in electroencephalographic abnormalities, elicited epileptic-form activity in the form of spikes, polyspikes and spike-wave complexes. Maximum incidence and severity of metaphit convulsions occurred 8 h after the injection (9/12, 75%, then abated gradually and disappeared 30 h

    Full Text Available We report case of a neonate who presented with recurrent seizure attacks at the age of 12 days. The baby was managed with anticonvulsant drugs. Eighteen days later, the neonate had repeated episodes of convulsion and was referred to our clinic. During initial work-up, we detected hypocalcaemia and started calcium supplementation along with anticonvulsants. There was another episode of convulsion after 3 days, which prompted us to do a repeat serum calcium assay. It showed hypocalcaemia which was persistent and resistant to calcium supplementation. On further investigation, hyperphosphatemia and raised concentration of parathyroid hormone were detected. Serum magnesium and 25(OHD level was normal. We suspected pseudohypoparathyroidism-and-hypocalcaemia was managed with calcium and vitamin D therapy. There was no further episode of convulsion and the baby was stable with corrected serum calcium and phosphorus levels during follow-up. Turk Jem 2015; 19: 65-66

    necessary to provoke convulsion of the forelimbs and/or facial muscles. Up to the TLS, if stimulation continued, the current intensity necessary to provoke the generalized seizures is called the threshold of generalized seizures (TGS). If stimulation is continued for about 2 seconds when the TGS is reached, rats still showed generalized clonic activity after stimulation ceased. When seizures stopped, a short period of immobility can be observed. The current intensity is called the threshold of prolonged seizures (TPS). The rats in the strong current group were stimulated up to the current level required to reach the TPS. In the course of stimulation, first, the TLS was recorded, then the TGS, and finally the TPS. The stimulation interval in one session was 10 minutes, repeated twice daily. The rats in the weak current group were only stimulated up to the current levels required to reach the TGS; first, the TLS was recorded and then the TGS was measured at the same time as the strong current group. Control animals were also equipped with a full electrode set and placed in the same conditions, but no stimulation took place, only electroencephalogram (EEG) recording at the same times as the experimental groups.MAIN OUTCOME MEASURES: ① Stimulation of the two experimental groups lasted for 11 weeks and then observation of their behavior and electroencephalogram recording continued for 4 weeks. The control group was also observed over a total of 15 weeks. ② Observing neuronal damage/loss in the hippocampus with a light microscope using a 250× visual field.RESULTS: All 36 Wistar rats were included in the final analysis. At the beginning of the experiment, the convulsive thresholds were all above 1 100 μA, although there were significant individual variations among rats of the same group. Those thresholds quickly declined during the initial 4 weeks of repetitive electrical stimulation. The convulsive thresholds approached a constant level in the 10th week after commencement

  14. 5-(2-Cyclohexylideneethyl)-5-ethyl barbituric acid (CHEB): correlation of hypnotic and convulsant properties with alterations of synaptosomal 45Ca2+ influx

    International Nuclear Information System (INIS)

    Male ICR mice were given either 5-(2-cyclohexylideneethyl)-5-ethyl barbituric acid (CHEB) alone or CHEB after a 1 h pretreatment with phenobarbital CHEB alone produced excitatory behavior but not convulsive seizures. Higher doses produced convulsive seizures resulting in death. Pretreatment with phenobarbital prevented seizure activity. In vitro, CHEB significantly inhibited 'fast-phase' K+-stimulated 45Ca2+ uptake into cerebrocortical synaptosomes. CHEB also significantly increased basal 45Ca2+ uptake. The addition of CHEB or pentobarbital to striatal synaptosomes inhibited 'fast-phase' K+-stimulated 45Ca2+ uptake and endogenous dopamine release. CHEB, but not pentobarbital, produced a time- and dose-dependent increase in the resulting release of endogenous dopamine from striatal synaptosomes. The results of this study show that CHEB possesses hypnotic activity if its lethal convulsant actions are blocked. The hypnotic actions of CHEB appear to correlate with inhibition of voltage-dependent calcium channels in brain synaptosomes. (Auth.)

    A modification of the good behavior game was used to reduce disruptive behaviors during a weekly library period of children in a fourth-grade class. Modifications included student input in designing rules, attempts to state rules in positive terms, observation of class behavior in the experimental (library) setting as well as in a comparison (classroom) setting, and librarian involvement in instituting the game coupled with teacher involvement in delivering reinforcers. Reinforcers consisted of special classroom activities conducted by the teacher with winning team members. Modification of the good behavior game did not detract from its effectiveness in reducing disruptive and off-task behavior. PMID:16795642

    Full Text Available Febrile convulsion (FC, an occurrence frequently encountered in everyday practice, is discussed in this article with a review of corresponding literature.Taking into account the extent of debate on the topic, from FC being considered a kind of epileptic seizure to its being viewed as a nonepileptic phenomenon, our aim is not to be judgmental regarding its nature in the present writing. Two distinct groups of children, who convulse with fever are described; one, the group whose neurological status is suboptimal and the other children who one who enjoy good health. In this review, the clinical aspects of management of fever, a forerunner of a seizure are emphasized. The other important aspect of handling a case of febrile convulsion consists of controlling the seizure, which should be done without any delay when it occurs. Nowadays, the drugs of choice are diazepines, used via the rectal, buccal or intranasal routes. The most important area of investigation is lumbar puncture in a child who has had a febrile convulsion, which will be discussed at the end.

    Febrile seizures are the most common type of convulsive events in children. It is generally assumed that the generalization of these seizures is a result of brainstem invasion by the initial limbic seizure activity. Using precollicular transection in 13-day-old rats to isolate the forebrain from the brainstem, we demonstrate that the forebrain is not required for generation of tonic-clonic convulsions induced by hyperthermia or kainate. Compared with sham-operated littermate controls, latency to onset of convulsions in both models was significantly shorter in pups that had undergone precollicular transection, indicating suppression of the brainstem seizure network by the forebrain in the intact animal. We have shown previously that febrile seizures are precipitated by hyperthermia-induced respiratory alkalosis. Here, we show that triggering of hyperthermia-induced hyperventilation and consequent convulsions in transected animals are blocked by diazepam. The present data suggest that the role of endogenous brainstem activity in triggering tonic-clonic seizures should be re-evaluated in standard experimental models of limbic seizures. Our work sheds new light on the mechanisms that generate febrile seizures in children and, therefore, on how they might be treated. PMID:26547277

    Full Text Available Electro Convulsive Therapy (ECT in pre-pubertal children is a controversial and underreported treatment. Even though the effectiveness and side effects of ECT in adolescents are comparable with those in adults, there is a pervasive reluctance to use ECT in children and adolescents. We report the case of a pre-pubertal child in an episode of severe depression with catatonic features, where a protracted course of ECT proved life-saving in spite of prolonged duration of seizures and delayed response to treatment. The case illustrates the safety and efficacy of ECT in children. Relevant literature is also reviewed along with the case report.

    Full Text Available Cassia Fistula is a popular Indian herb which is used as tonic, laxative, anti-pyretic, astringent, febrifuge, strong purgative etc. The aim of present study was to evaluate anticonvulsant activity of methanolic extract of seeds of Cassia Fistula against pentylenetetrazol (PTZ induced convulsions in mice. All the animals were divided into four groups of six mice each and were injected PTZ (60mg/kg intraperitonially Group I was served as toxic control, Group II was pretreated with  Gabapentin (200mg/kg P.O.. Group III was pretreated with  methanolic extract of seeds of Cassia Fistula (100 mg/kg P.O. for 7 days. Group IV was pretreated with  methanolic extract of seeds of Cassia Fistula (200mg/kg P.O. for 7 days.The result shows that methanolic extract of seeds of Cassia Fistula significantly reduced duration of clonic convulsions and also delayed the onset of convulsions induced by pentylenetetrazol. The result was expressed as mean ± SEM and were statistically analyzed by one way ANOVA. It is concluded that methanolic extract of seeds of Cassia Fistula can show anticonvulsant activity against pentylenetetrazol induced convulsions in mice.

    Group III metabotropic glutamate receptors (mGluR4, 6, 7, 8) are negatively coupled to adenylate cyclase and, when activated presynaptically, decrease the release of glutamate and GABA. We have used intracerebroventricular injections of agonists and antagonists believed to act selectively on these receptors to study the pro- or anti-convulsant effects of mGluR III activation in nonepileptic (Swiss-Webster) and epileptic (DBA/2) mice. In both mouse strains the prototypic agonists L-2-amino-4-phosphonobutanoate (LAP4) and L-serine-O-phosphate are proconvulsant. The supposed antagonists (S)-2-methyl-2-amino-4-phosphonobutanoate (MAP4) and (RS)-alpha-methyl-4-phosphonophenylglycine (MPPG), have a predominantly proconvulsant effect. (S)-alpha-methyl-3-carboxyphenylalanine, which is a potent and selective antagonist for LAP4 in the cortex, is anticonvulsant in DBA/2 mice and decreases the convulsant effect of N-methyl-D-aspartate, 3,5-dihydroxyphenylglycine, LAP4 and MPPG in Swiss-Webster mice. These data suggest that reduced inhibitory transmission may be more significant than reduced synaptic release of glutamate following group III mGluR activation. PMID:8856700

    The severe psychological reactions of most parents to the first febrile convulsions of their child contrast with the doctors' consideration of febrile convulsions as a simple and benign phenomenon. Fifty-two parents whose child had been admitted with febrile convulsions were interviewed about their immediate and long-term reactions. Most of the parents knew little about febrile convulsions before the fit. Parents with previous knowledge of febrile convulsions took more appropriate measures during the fit than parents without such knowledge. Sixty per cent of the parents slept restlessly for some time after the fit, 13% watched their child at night, and 29% had dyspeptic symptoms. Parents of young children should as a routine be offered general information by the family doctor about fever and febrile convulsions. Parents who have watched their child during a fit need specific information in order to avoid long-term reactions. PMID:2058397

    Full Text Available Febrile seizure is one of the most common neurological problems during childhood. The etiology and pathogenesis of febrile seizure remain unknown. However, several factors such as vitamin B6 deficiency, electrolyte disturbances, and reduction in serum zinc, selenium, magnesium levels, and low gamma - aminobutyric acid (GABA levels are thought to play a role in the pathogenesis of febrile seizure. The present study included twenty children from 10 families, 11 were male and 9 were female. Each family has at least 2 members with a history of febrile convulsion. All cases were subjected to the following: Determination of serum levels of copper, zinc, magnesium, selenium level in serum, and plasma level of γ-aminobytaric acid (GABA. Serum levels of selenium and GABA were statistically significantly low in comparison with controls. Serum copper was statistically significantly higher in cases than controls, while serum zinc showed no significant changes in the cases of febrile convulsion compared with the control group. The mean Zn level in the serum of febrile convulsion was found to be at lower level than in the control group. The serum magnesium was significantly low in cases than controls. The logistic regression model in our study shows that Selenium and Magnesium have protective effects, while Copper has causative effect.

    In order to further elucidate a possible role of neuropeptides and GABA in the pathogenesis of febrile convulsions, we studied changes of immunoreactive-arginine vasopressin (IR-AVP), IR-somatostatin (IR-SRIF) and gamma-aminobutyric acid (GABA) in the rat brain after febrile convulsions induced by ultra-red light (UR). Male Wistar rats at 16 days of age irradiated with UR developed generalized convulsions after 4.9 +/- 0.5 min irradiation. Six rats were killed by microwave irradiation 3 min after UR irradiation prior to convulsion development, and 29 rats were killed either 0 min, 2 h, 6 h, 24 h or 48 h after febrile convulsions. Non-irradiated rats served as controls. The rat brain was dissected into 4 regions; amygdala, hypothalamus, cortex and hippocampus, and subjected to radioimmunoassays. IR-AVP levels in hypothalamus were increased 3 min after UR and decreased at 2 h and 6 h after the convulsions. IR-SRIF levels were increased in cortex and hippocampus at 3 min after UR and 0 min after the convulsions. The GABA content increased in all regions tested at 2 h and 6 h after the convulsions. These results suggest that AVP, SRIF and GABA may be involved in the pathogenesis of febrile convulsions in different ways. PMID:8649210

    1987-01-01

    The ability of various compounds to antagonise the 5-MeODMT induced prolongations of latency and duration of postdecapitation convulsions (PDCs) were compared. The 5-hydroxytryptamine (5-HT) receptor antagonists, mianserin, methergoline, cinanserin and methysergide antagonised the 5-MeODMT (0.5 to 4.0 mg/kg) induced prolongations of latency to onset of convulsions substantially and to a lesser extent the prolongation of duration. The efficacy of the 5-HT antagonists for blocking 5-MeODMT changes of PDCs was roughly of the order mianserin greater than cinanserin greater than methysergide greater than methergoline. Pirenperone, the 5-HT2 antagonist, and pimozide, the dopamine receptor antagonist did not antagonise the 5-MeODMT induced changes. Mianserin, methergoline, cinanserin and methysergide, by themselves, prolonged the duration of PDCs but did not affect latency. Pirenperone (0.25 mg/kg) prolonged both the latency and duration of the PDCs while pimozide (0.5-2.0 mg/kg) had no effect upon PDCs. This evidence suggests that 5-MeODMT induced changes of PDCs are mediated via 5-HT1 receptors and thus a reliable model to combine with other measures of spinal function is suggested. PMID:3562388

    1986-12-01

    The fiberglass-reinforced plastics industry and the literature on controlling exposures to toxic substances were surveyed to select work practices and housekeeping conditions that might be useful in reducing workers' exposures to styrene. A training program was developed to teach the selected behaviors to workers, and a behavior maintenance program was developed to encourage their continued use after training. These behavioral controls were introduced to appropriate workers in three different plants and were effective in changing all selected behaviors and conditions. Statistically reliable reductions in workers' exposures to styrene accompanied the changes in behaviors. All improvements were maintained throughout the course of data collection. The research provides a clear demonstration that behavioral controls can be used reliably to reduce workers' exposures to toxic substances. PMID:3799480

  3. Soman- or kainic acid-induced convulsions decrease muscarinic receptors but not benzodiazepine receptors

    International Nuclear Information System (INIS)

    [3H]Quinuclidinyl benzilate (QNB) binding to muscarinic receptors decreased in the rat forebrain after convulsions induced by a single dose of either soman, a potent inhibitor of acetylcholinesterase, or kainic acid, an excitotoxin. A Rosenthal plot revealed that the receptors decreased in number rather than affinity. When the soman-induced convulsions were blocked, the decrease in muscarinic receptors at 3 days was less extensive than when convulsions occurred and at 10 days they approached control levels in most of the brain areas. The most prominent decrements in QNB binding were in the piriform cortex where the decline in QNB binding is probably related to the extensive convulsion-associated neuropathology. The decrements in QNB binding after convulsions suggest that the convulsive state leads to a down-regulation of muscarinic receptors in some brain areas. In contrast to the decrease in QNB binding after convulsions, [3H]flunitrazepam binding to benzodiazepine receptors did not change even in the piriform cortex where the loss in muscarinic receptors was most prominent. Thus, it appears that those neuronal processes that bear muscarinic receptors are more vulnerable to convulsion-induced change than those with benzodiazepine receptors

  4. Bicycloorthocarboxylate convulsants. Potent GABAA receptor antagonists

    International Nuclear Information System (INIS)

    4-t-Butyl-1-(4-bromophenyl)-bicycloorthocarboxylate antagonizes gamma-aminobutyric acid (GABA)-mediated relaxation at a functional insect nerve-muscle synapse, mimicking the action of picrotoxinin, suggesting that it causes GABA antagonism through blockade of the chloride ionophore. It is also a potent GABAA receptor antagonist, inhibiting the binding of [35S]t-butyl-bicyclophosphorothionate ([35S]TBPS) to EDTA/water-dialyzed human brain P2 membranes. Structure-activity relationships of 74 1,4-bis-substituted bicycloorthocarboxylates, mostly new compounds, reveal that for high potency as a GABAA receptor antagonist the optimal 4-substituent is a C4 to C6 branched chain alkyl or cycloalkyl group (e.g., t-butyl, s-butyl, or cyclohexyl) and the optimal 1-substituent is a phenyl moiety with one or more electron-withdrawing groups (e.g., 4-cyano, 4-bromo, 4-chloro, 3,4-dichloro, or pentafluoro). Bicycloorthocarboxylate inhibitors of [35S]TBPS binding with IC50 values of 5-10 nM exceed by several-fold the potency of any GABAA receptor antagonist previously reported. The 4-t-butyl-1-(4-azidophenyl) analog, synthesized as a candidate photoaffinity label, gives an IC50 of 315 nM. The potency of bicycloorthocarboxylates for decreasing [35S]TBPS binding generally correlates with their toxicity, i.e., compounds without inhibitory activity in this brain receptor assay are of low toxicity on intraperitoneal administration to mice, and the analogs most potent as inhibitors are generally those most toxic to mice (e.g., IC50 of 5 nM and LD50 of 0.06 mg/kg for 4-t-butyl-1-(4-cyanophenyl)-bicycloorthocarboxylate). The effects of phenyl substituents on the potency of the orthobenzoates as GABAA receptor antagonists are similar to those on toxicity

  6. The effects of radionuclides on animal behavior

    International Nuclear Information System (INIS)

    Concomitant with the expansion of the nuclear industry, the concentrations of several pollutants, radioactive or otherwise, including uranium, caesium, cadmium and cobalt, have increased over the last few decades. These elemental pollutants do exist in the environment and are a threat to many organisms. Behavior represents the integration of all the anatomical adaptations and physiological processes that occur within an organism. Compared to other biological endpoints, the effects of pollutants on animal behavior have been the focus of only a few studies. However, behavioral changes appear to be ideal for assessing the effects of pollutants on animal populations, because behavior links physiological functions with ecological processes. The alteration of behavioral responses can have severe implications for survival of individuals and of population of some species. Behavioral disruptions may derive from several underlying mechanisms: disruption of neuro-sensorial activity and of endocrines, or oxidative and metabolic disruptions. In this review, we presented an overview of the current literature in which the effects of radioactive pollutants on behavior in humans, rodents, fish and wildlife species are addressed. When possible, we have also indicated the potential underlying mechanisms of the behavioral alterations and parameters measured. In fried, chronic uranium contamination is associated with behavior alterations and mental disorders in humans, and cognitive deficits in rats. Comparative studies on depleted and enriched uranium effects in rats showed that chemical and radiological activities of this metal induced negative effects on several behavioral parameters and also produced brain oxidative stress. Uranium exposure also modifies feeding behavior of bivalves and reproductive behavior of fish. Studies of the effects of the Chernobyl accident shows that chronic irradiation to 137Cs induces both nervous system diseases and mental disorders in humans leading to

    Gentianine has been shown to have a protective effect on hippocampal CA1 neurons in rats subjected to recurrent febrile convulsion (FC).The present study sought to explore the possible mechanism of gentianine by intraperitoneally injecting gentianine into rats with warm water-induced FC.The results revealed that neuronal organelle injury was slightly ameliorated in the hippocampal CA1 region.The level of glutamate was decreased,but the level of γ-aminobutyric acid was increased,as detected by ninhydrin staining.In addition,glutamate acid decarboxylase expression in hippocampal CA1 was increased,as determined by immunohistochemistry.The results demonstrated that gentianine can ameliorate FC-induced neuronal injury by enhancing glutamate acid decarboxylase activity,decreasing glutamate levels and increasing γ-aminobutyric acid levels.

    Mesial temporal sclerosis (MTS) is the most common lesion in patients who require epilepsy surgery, and approximately 50% of patients with MTS have a history of prolonged febrile convulsion (PFC) in childhood. The latter led to the hypothesis that convulsive status epilepticus, including PFC, can cause MTS. Our recently published data on children investigated within 5 days of a PFC showed that children investigated by MRI within 48 h of a PFC had large hippocampal volumes and prolongation of T2 relaxation time. Patients investigated >48 h from a PFC had large hippocampal volumes and normal T2 relaxation time. These data are strongly suggestive of hippocampal oedema that is resolving within 5 days of a PFC, but do not exclude the possibility of a pre-existing hippocampal lesion. Fourteen children from the original study had follow-up investigations carried out 4-8 months after the acute investigations. Of the 14 patients, four have had further seizures. Two had short febrile convulsions, one had PFC and one had non-febrile seizures. There was a significant reduction in hippocampal volume and T2 relaxation time between the first and second investigations, and there is now no difference in hippocampal volume or T2 relaxation time in patients compared with a control population. Moreover, there is a significant increase in hippocampal volume asymmetry in patients at follow-up when compared with initial data. Five out of 14 patients had asymmetry outside the 95th percentile for control subjects and, of these, three had one hippocampal volume outside the lower 95% prediction limit for control subjects. A reduction in hippocampal volume or T2 relaxation time, into or below the normal range between the first and second scans, indicates that the earlier findings are temporary and are strongly suggestive of hippocampal oedema as the abnormality in the initial investigations. The change in hippocampal symmetry in the patient group is consistent with injury and neuronal loss

    Full Text Available Objective: Febrile convulsion is the most common disorder in childhood with good prognosis. There are different hypotheses about neurotransmitters and trace element (such as zinc changes in cerebrospinal fluid and serum, which can have a role in pathogenesis of febrile convulsion. The aim of the present prospective analytical case-control study was to determine whether there was any changes in serum zinc level in children with febrile convulsion during seizure.Methods: Ninety-two children aged 6 months to 5 years were divided into three groups: group A, 34 children with febrile convulsion, group B, 40 children having fever without convulsion, and group C, and 18 children with non-febrile convulsion. Serum zinc levels for the three groups were estimated by atomic absorption spectrophotometry (AAS. Data were analyzed to compare zinc level among the three groups using appropriate statistical tools employing SPSS 13.Findings: Serum zinc levels of groups A, B, and C had a mean value of 76.82±24.36mg/1, 90.12±14.63 mg/1 and 94.53±17.39 mg/l, respectively. Serum zinc level of group A was lower than those of the other two groups (P<0.006. It was also lower in group B than in group C (P<0.006.Conclusion: These findings revealed that serum zinc level decreases during infection; this decrease was more significant in patients with febrile convulsion.

  12. Development, maternal effects, and behavioral plasticity.

    Behavioral, hormonal, and genetic processes interact reciprocally, and differentially affect behavior depending on ecological and social contexts. When individual differences are favored either between or within environments, developmental plasticity would be expected. Parental effects provide a rich source for phenotypic plasticity, including anatomical, physiological, and behavioral traits, because parents respond to dynamic cues in their environment and can, in turn, influence offspring accordingly. Because these inter-generational changes are plastic, parents can respond rapidly to changing environments and produce offspring whose phenotypes are well suited for current conditions more quickly than occurs with changes based on evolution through natural selection. I review studies on developmental plasticity and resulting phenotypes in Belding's ground squirrels (Urocitellus beldingi), an ideal species, given the competing demands to avoid predation while gaining sufficient weight to survive an upcoming hibernation, and the need for young to learn their survival behaviors. I will show how local environments and perceived risk of predation influence not only foraging, vigilance, and anti-predator behaviors, but also adrenal functioning, which may be especially important for obligate hibernators that face competing demands on the storage and mobilization of glucose. Mammalian behavioral development is sensitive to the social and physical environments provided by mothers during gestation and lactation. Therefore, maternal effects on offspring's phenotypes, both positive and negative, can be particularly strong. PMID:24820855

    In our previous study, the saponin-rich fraction (SRF) of adventitious root extract of Ficus religiosa L. (Moraceae) was shown to have an anticonvulsant effect in acute animal models of convulsions. The present study was envisaged to study the effect of SRF in the pentylenetetrazol (PTZ) kindling mouse model and its associated depression and cognition deficit. Treatment with the SRF (1, 2 and 4 mg/kg; i.p.) for 15 days in kindled mice significantly decreased seizure severity on days 5, 10 and 15 when challenged with PTZ (35 mg/kg; i.p.). Marked protection against kindling-associated depression was also observed on days 10 and 15 in the SRF-treated groups when tested using the tail-suspension test. However, the SRF treatment failed to protect kindling-associated learning and memory impairments in the passive shock avoidance paradigm. The observed behavioral effects were corroborated with modulation in the levels of noradrenaline, dopamine, serotonin, GABA and glutamate in discrete brain regions. PMID:23332444

    Injuries after an epileptic convulsion have been seen commonly such as burns, head injury and dislocation of the extremities. But fractures of the extremities due to convulsion are rare. External trauma mechanism is not necessary for extremity fractures. Muscle contractions can cause increased load on the skeleton and it can be complicated by dislocation andor fracture of extremities. Almost 1-4% of all the shoulder dislocations are posterior. In this case report we present a 32 year old male patient who had bilateral posterior fracture and dislocation of proximal humerus after convulsion. We would like to emphasize that it is so important to make systemic examination and evaluation of the patients who were admitted to emergency department after epileptic convulsion. PMID:27183951

    Fifty parents of 36 consecutive children admitted to hospital with their first febrile convulsion were interviewed shortly after the event. Very few parents voluntarily said that they had thought their child was dying, but when asked specifically the majority said they had thought the child was dying or likely to die. This common fear should be kept in mind when discussing febrile convulsions with parents, who are unlikely to volunteer the information. PMID:7274593

    Convulsions represent a frequent pediatric emergency in southern Benin and Nigeria, where they are estimated to occur in 15% of hospitalizations. The principal cause is fever during a malarial attack. The health team provides symptomatic treatment and searches for the etiology so that adequate treatment can be provided. For the family faced with convulsions, the major concern is to bring the child out of the convulsive state at almost any price. The 3 products most commonly used by parents and other caretakers are cod liver oil, honey, and lemon, which are administered orally often in combination in hopes of provoking vomiting or stimulating the child to regain consciousness. Other substances sometimes administered include cow or cat urine, garlic or onion, and rubbing alcohol. Articles such as spoons or sticks or fingers may be used in attempts to loosen the jaws and avoid blockages. Flagellation may be used to revive the child. Scarification or fumigation may be done to combat sorcery or chase away evil spirits. A hand or leg may be plunged into boiling water or fire to revive the child from a postconvulsive coma. Use of these techniques explains the high rate of mortality or morbidity following convulsions, Morbid states induced by traditional treatments of convulsions may include false bronchial route, ocular or cutaneous burns buccal lesions, injuries to the nasal cavities or lips, and edema of the cheeks. A survey of parents indicated that 37% of families interviewed had been present at a convulsive crisis of their children or siblings. Convulsions were considered a natural ailment by only 55% and a sign of sorcery and malediction by 36%. 84% of parents surveyed knew about possible sequelae of traditional treatments and 40% used them. 90% of families knew about possible sequelae of traditional treatments but explained them by the seriousness of the convulsions or sorcery. 69% felt that more adequate treatment should be found.

    Febrile convulsion (FC) is the most common type of seizure in childhood that occurs in 2-5 % of the children younger than 6 years. Interleukin 1β (IL-1β) is a cytokine that contributes to febrile inflammatory responses. There are conflicting results on increasing this cytokine in serum during FC. Thus we measured IL-1ß in febrile children with or without seizure. 60 febrile children (6 months to 5 years old) were divided in two groups, one group consisted of 30 children with FC, the other group consisting of 30 children without seizure which served as control. Blood samples were collected from members of both groups and serum samples were prepared. Interleukin 1β concentrations were measured using a commercial enzyme-linked immunosorbent assay (ELISA) kit. We found that there was a difference in serum levels of interleukin 1β between FC and control group but it was not significant. This result may be due to the low number of samples or the result of interleukin 1β binding to some large proteins such as α2-macroglobolin, complement and soluble type 2 Interleukin 1 receptor, that affected the free interleukin 1β concentration.We could not find a significant relationship between serum interleukin 1β concentration and FC.

  5. Vasopressin: its role in antipyresis and febrile convulsion.

    Veale, W L; Cooper, K E; Ruwe, W D

    1984-02-01

    When pyrogenic substances are injected intravenously into experimental animals, a sequence of events is set in motion which involves the hypothalamus and perhaps other portions of the diencephalon to produce a febrile response. We now present evidence that the brain produces its own endogenous antipyretic which may serve as a means of controlling the extent of the fever. When arginine vasopressin is perfused through the lateral septal area of the hypothalamus of the sheep, fever is suppressed. Vasopressin alone does not lower normal body temperature when perfused through this region of the brain. In addition, evidence is provided to indicate that vasopressin is released within the lateral septal area during the febrile response. It is concluded that, in fever, arginine vasopressin may be released in the lateral septal area of the brain and serve as an endogenous antipyretic. Results indicate that, following an initial application of vasopressin into the brain itself, a subsequent similar administration of vasopressin produces seizure-like activity. Therefore, it is suggested that this release of arginine vasopressin may contribute to the production of febrile convulsion. PMID:6722595

  6. Microstructure and effective behavior - analysis and computation

    International Nuclear Information System (INIS)

    Material behavior is determined by features on a number of length scales between the atomistic and macroscopic scale. As full direct resolution of all scales is out of reach there is an intense research on analytical and computational tools that can bridge different scales and a number of different schemes have been proposed. One key issue is to identify which information on the finer scale is needed to determine the behavior on the coarser scale. To shed some light on this issue we will focus on number of case studies to understand the passage from macroscopic scales, where the material is described by a multi-well non-convex energy, to macroscopic behavior. Examples include shape-memory materials, new giant magnetostrictive materials and nematic elastomers. Similar ideas have been used by others and by us to understand dislocation arrangements, blistering of thin films and magnetic microstructures. We will discuss three algorithmic approaches to analyze effective behavior: purely analytical, hybrid analytical-computational and computation inspired by analysis. Refs. 5 (author)

    A numerical study of the effects of copper and silver vapours on the air arc behavior is performed. The commercial software FLUENT is adapted and modified to develop a two-dimensional magneto-hydrodynamic (MHD) models of arc with the thermodynamic properties and transport coefficients, net emission coefficient for the radiation model of 99% ai-1% Cu, 99% air-1% Ag, and pure air, respectively. The simulation result demonstrates that vaporization of the electrode material may cool the arc center region and reduce the arc velocity. The effects of Ag vapour are stronger compared to those of Cu vapour.

    The results of a follow up study of 155 Dutch children who visited the emergency room of an urban paediatric hospital after experiencing their first febrile seizure are presented. Median follow up time was 38 months (range 27-60). Of these 155 initially untreated children 58 (37%) suffered at least one, 47 (30%) at least two and 27 (17%) at least three recurrent seizures. The recurrence hazard after any seizure was highest in the first six months, and dropped markedly after 6 months without seizures. The effect of the various postulated risk factors on the occurrence of any recurrent seizure and three or more recurrences was assessed. A first degree family history of febrile or nonfebrile seizures appears to be a predictor of multiple recurrences; an age of at least 30 months and a temperature of 40.0 degrees C or higher at the initial seizure are associated with a decreased risk. Several factors act together on the risk of recurrent seizures, sometimes in opposite directions. By considering the action of all relevant factors (age at onset, family history and features of the initial febrile seizure) subgroups of children with one year seizure recurrence rates as low as 15% and as high as 48% were identified.

The percent of time spent in the open arms of maze (OAT % and percent of entries in the open arms (OAE % were accounted for anxiety evaluation. Increase in OAT % and OAE % indicated an anxiolytic effect. Finally,the obtained data was analyzed by means of Any-Maze software and P<0.05 was taken as the significant level. Results: Kindling significantly (P<0.05 increased anxiety response in rats for at least 24h following the last seizure (decrease in OAT % and OAE %. Administeration of diazepam and Matricaria Recutita induced a significant increase in OAT % and OAE %, thereby . displaying a decrease in the anxiety in the kindled rats (P<0.05. Activity rate of the animals increased in the extract-treated group. Conclusion: The results of the present study showed that Matricaria Recutita was able to improve elevated levels of anxiety in kindled rats. Therefore, further works are needed to elucidate the extent and mechanism of these effects.

    2016-07-01

    Convulsive status epilepticus (CSE) is a neurological emergency in adults and children. However, whether a particular benzodiazepine is of superior efficacy and safety in management of CSE is controversial. We performed a meta-analysis to compare the outcome of lorazepam and diazepam for treating CSE. We searched the PubMed, Medline, Embase, Cochrane Central Register of Controlled Trials, and Google Scholar databases from 1966 to February 2014. No language restriction was applied. Reference lists of all the selected articles were hand-searched for any additional trials. Trial quality was assessed using the modified Jadad scale and the Consolidated Standards Of Reporting Trials (CONSORT) checklist. Two authors independently extracted data from all eligible studies, including study design, participants, interventions, and outcomes. The data was analyzed using fixed-effects or random-effects models with mean differences and risk ratios for continuous and dichotomous variables, respectively. A total of six studies involving 970 patients were included in this analysis. The majority of patients were children (n=574) and 396 patients were adults. Meta-analysis showed no significant difference between the two treatment groups regarding seizure control and adverse effects regardless of patient age. This meta-analysis demonstrates that diazepam and lorazepam have equal efficacy and side effects for treating CSE in adults and children, and either can be chosen as a reasonable first-line therapy. More high quality randomized controlled trials are needed to support this finding. PMID:27052258

    In order to improve our understanding of the effects that the equilibrium phase behavior and structure of amphiphiles have on the emulsification process and the properties of emulsions stabilized by these amphiphiles, we have exploited the known phase behavior of polyoxyethylene-polyoxypropylene-polyoxyethylene (POE-POP-POE) amphiphilic block copolymers (Pluronics) in the presence of two immiscible solvents. Specifically, we considered ternary systems consisting of Pluronic F38, L64, P84, P104, or L121 with water and p-xylene which exhibit a very rich phase behavior, including a variety of water-continuous and oil-continuous lyotropic liquid crystalline (LLC) phases. We prepared emulsions having the same (final) compositions but through different emulsification paths, and evaluated the emulsions on the basis of homogeneity and droplet size. We found finer and more homogenous emulsions to result when O/lamellar gel structures (as revealed by small-angle X-ray scattering) were formed during the emulsification process, or when the emulsification path traversed the lamellar LLC phase. This can be attributed to the favorable properties of the lamellar structure: high oil solubilization capacity with concurrent facile dispersibility in water, relatively low interfacial tension, and relatively low viscosity. The findings reported here are relevant to the preparation of emulsions for diverse applications such as skin-care products, pharmaceuticals, food products, coatings, inks, agrochemicals, oil dispersants, and nanomaterials synthesis.

    We report a 57-year-old woman with progressive gait disturbance, headache, character change, convulsion and coma. She was well until 55 years of age, when she noted an onset of unsteady gait. At times she experienced transient weakness in her right hand, which was followed some difficulty in articulation. She was admitted to our service for the work up on April 6, 1992. Neurologic examination at that time revealed an alert Japanese lady in no acute distress. She was oriented to all spheres, however, she was somewhat bradyphrenic and had some disturbance in recent memory. Higher cerebral functions appeared intact. The visual acuity and visual fields were normal as were the optic fundi. Pupils were round and isocoric reacting promptly to light. Ocular movement was full, however, horizontal nystagmus was noted upon right lateral gaze. The sensation of the face was intact. She showed right facial paresis of the central type. Hearing was intact. She showed slurred speech and some difficulty in swallowing. The tongue was deviated to the right. Her gait was wide based and unsteady; tandem gait was difficult, however, walking on toes and on heels were performed well. No cerebellar ataxia was noted, but she showed some clumsiness in her right hand. Deep reflexes were symmetric and normally reactive; plantar response was extensor bilaterally. Sensation was intact; no meningeal sign was elicited. Routine laboratory work up was unremarkable; the CSF was under a borderline pressure (180 mmH2O) and contained 39 mg/dl of protein and 59 mg/dl of sugar. Cranial CT scan revealed diffuse low density areas involving bilateral cerebral white matter as well as the brain stem; MRI revealed high signal intensity lesions in those areas; gadolinium enhancement was negative; cortical sulci were effaced and the anterior part of the left lateral ventricle was compressed without deviation of the midline structure. The patient was treated with steroid pulse therapy without effect. She was

Interleukin 1β concentrations were measured using a commercial Enzyme-linked immunosorbent assay (ELISA kit.We found that there was a difference in serum levels of Interleukin 1β between FC and control  group but  it was not  significant. This result may be due to  the low number  of samples  or  the  result  of  Interleukin  1β  binding  to  some  large proteins  such  as  α2- macroglobolin, complement and soluble type 2 Interleukin 1 receptor, that affected the free Interleukin 1β concentration.We could not find a significant relationship between serum Interleukin 1β concentration and FC.convulsion (FC is the most common type of seizure in childhood that occurs in 2-5 %  of  the  children younger than  6  years. Interleukin 1β (IL-1β is a cytokine that contributes to febrile inflammatory responses. There are conflicting results on increasing this cytokine in serum during FC. Thus we measured IL-1ß in febrile children with or without seizure.60 febrile children (6 months  to 5 years old were divided in two groups, one group consisted of 30 children with FC, the other group consisting of 30 children without seizure which served as control.

    Full Text Available Introduction: The febrile convulsion (FC occurs in neurologically normal children aged between six months and five years and it is defined as convulsions occurred during fever and in the absence of central nervous system (CNS infection, electrolyte imbalance, diseases affecting directly CNS, and history of afebrile convulsion. The aims of this study were to determine the serum levels of selenium in patients with recurrent FC and to compare them with those of healthy children. Materials and Methods: The study included 61 pediatric patients diagnosed with recurrent FC. At the same session, 54 healthy children who admitted to our pediatric clinic for routine controls without history of fever and convulsion, are assigned as control group. The serum level of selenium was measured by atomic absorption spectrometric method (hydride technique.Results: Mean level of selenium was determined as 67.10±8.87 µg/L in patients and 81.99±13.13 µg/L in control group; the difference was statistically significant (p<0.05. Discussion: The lower serum levels of selenium in patients with recurrent FC may be the cause of triggering of convulsion or may contribute to its recurrence. Further studies are necessary to clarify this relationship. (Jo­ur­nal of Cur­rent Pe­di­at­rics 2011; 9: 110-5

    Ninety-four children consecutively admitted to the hospital between January 1980 and December 1982 with their first febrile convulsion (FC) were studied to assess the influence of the degree of pyrexia on the recurrence rate of FC. Thirty-eight of sixty-three children between 6 and 18 months of age (the peak incidence of FC) with fever above 40 degrees C were almost seven times less likely to have subsequent convulsions with fever, than those whose initial febrile convulsion was associated with a lower degree of pyrexia. It is suggested that the degree of pyrexia is a factor that influences the recurrence of FC. This may explain why some children have a reduced frequency of subsequent FC compared with others who appear to be at comparable risk. PMID:3698455

    Full Text Available Red blood cells carry oxygen in the body and Glucose-6-Phosphate Dehydrogenase protects these cells from oxidative chemicals. If there is a lack of Glucose-6-Phosphate Dehydrogenase, red blood cells can go acute hemolysis. Convulsion is a rare presentation for acute hemolysis due to Glucose-6-Phosphate Dehydrogenase deficiency. Herein, we report a case report of a Glucose-6-Phosphate Dehydrogenase deficiency diagnosed patient after presentation with convulsion. A 70 year-old woman patient had been hospitalized because of convulsion and fatigue. She has not had similar symptoms before. She had ingested fava beans in the last two days. Her hypophyseal and brain magnetic resonance imaging were normal. Blood transfusion was performed and the patient recovered.

    Socio-demographic data, initial clinical manifestations, outcome and family aggregation of febrile convulsion (FC) were compared between 85 population and 364 multicenter patients. More patients presented with clustering of seizures and had recurrence of FC in multicenter group than in population group. Multicenter patients had more fever episodes per year, more day-card attendance and a higher incidence of FC history in their parents. The odds ratio of FC in the siblings was 6:1 in population group and 12:1 in multicenter group. Lower socioeconomic status influenced the presence of FC in the sibling of population group. Instead, FC histories in the father and paternal cousins of probands had influence on the presence of FC in the siblings of multicenter group. We conclude that the population FC sample rather than the hospital sample is the more representative. And there are differences not only in the clinical manifestations but also in the effect of environmental and genetic influences on the family aggregation in population and hospital patients.

    Introduction. This study was designed to identify the delays and factors related to and predicting the cessation of generalized convulsive SE (GCSE). Methods. This retrospective study includes 70 consecutive patients (>16 years) diagnosed with GCSE and treated in the emergency department of a tertiary hospital over 2 years. We defined cessation of SE stepwise using clinical seizure freedom, achievement of burst-suppression, and return of consciousness as endpoints and calculated delays for these cessation markers. In addition 10 treatment delay parameters and 7 prognostic and GCSE episode related factors were defined. Multiple statistical analyses were performed on their relation to cessation markers. Results. Onset-to-second-stage-medication (p = 0.027), onset-to-burst-suppression (p = 0.005), and onset-to-clinical-seizure-freedom (p = 0.035) delays correlated with the onset-to-consciousness delay. We detected no correlation between age, epilepsy, STESS, prestatus period, type of SE onset, effect of the first medication, and cessation of SE. Conclusion. Our study demonstrates that rapid administration of second-stage medication and early obtainment of clinical seizure freedom and burst-suppression predict early return of consciousness, an unambiguous marker for the end of SE. We propose that delays in treatment chain may be more significant determinants of SE cessation than the previously established outcome predictors. Thus, streamlining the treatment chain is advocated.

    To assess the role of routine investigations in children presenting with their first febrile convulsion, the results of investigations carried out in 328 children over a 2-year period were reviewed. Lumber puncture was performed in 96% of cases and resulted in the detection of 4 cases of unsuspected meningitis, one of which was bacterial. 2 children had normal lumbar punctures on admission but developed meningococcal meningitis within 48 hours. Sugar, calcium, urea, and electrolyte estimations, and blood counts were commonly performed but were unhelpful. We suggest that lumbar puncture in those children presenting with their first febrile convulsion under the age of 18 months is the only useful routine investigation. PMID:848997

    The effects of Soman and paraoxon on cerebral metabolic rate (CMRg) and the levels of various metabolites in rate brain were investigated. In non-convulsing animals, 0.8 of the paraoxon LD50 and 0.5 of the Soman LD50 tended to lower CMRg. A higher dose of Soman, 0.8-0.95 of the LD50, resulted in convulsive seizures in some but not all of the animals. In convulsing rats the CMRg and lactate levels were elevated primarily in the cortex and thalamus/basal ganglia. Decreased ATP and glucose levels with an elevated CMRg and lactate concentration was observed in the cortex, suggesting that Soman may be uncoupling oxidative phosphorylation. Pretreatment with atropine prevented the behavioral manifestations and the elevated CMRg but not the hyperglycemia produced by an 0.8 LD50 dose of Soman. These results suggest that Soman-induced convulsions are similar to those produced by other central nervous system (CNS) excitatory agents in that only certain brain regions are affected. The use of atropine to block the CNS disturbances produced by Soman appears to be effective also does not result in the extensive depression of CMRg observed with TAB, a mixture of trimedoxime, atropine and benactyzine.

  12. Effects of light on brain and behavior

    It is obvious that light entering the eye permits the sensory capacity of vision. The human species is highly dependent on visual perception of the environment and consequently, the scientific study of vision and visual mechanisms is a centuries old endeavor. Relatively new discoveries are now leading to an expanded understanding of the role of light entering the eye in addition to supporting vision, light has various nonvisual biological effects. Over the past thirty years, animal studies have shown that environmental light is the primary stimulus for regulating circadian rhythms, seasonal cycles, and neuroendocrine responses. As with all photobiological phenomena, the wavelength, intensity, timing and duration of a light stimulus is important in determining its regulatory influence on the circadian and neuroendocrine systems. Initially, the effects of light on rhythms and hormones were observed only in sub-human species. Research over the past decade, however, has confirmed that light entering the eyes of humans is a potent stimulus for controlling physiological rhythms. The aim of this paper is to examine three specific nonvisual responses in humans which are mediated by light entering the eye: light-induced melatonin suppression, light therapy for winter depression, and enhancement of nighttime performance. This will serve as a brief introduction to the growing database which demonstrates how light stimuli can influence physiology, mood and behavior in humans. Such information greatly expands our understanding of the human eye and will ultimately change our use of light in the human environment.

    Objective To explore the clinical characteristics of roseola infantmn with febrile convulsions.Methods All cases with roseola infantum or with febrile convulsions were retrospectively collected who were confirmed during January 2005 to February 2008. There were 31 cases of roseola infantum with febrile convulsions. Their clinical features were compared with cases of roseola infantum without febrile convulsions and eases of other febrile convulsions,respectively, and further analyzed with literature. Results There were 17.1% (3 1 / 181 ) roseola infantum with febrile convulsions among febrile convulsions and 24.4% (31/127)among febrile convulsions less than 2 years;The incidence of roseola infantum with febrile convulsions was 15.7% (31/198) among roseola infantum. The median age of roseola infantum with febrile convulsions was less than that of other febrile convulsions. There were no significant differences in sex, age, maximum body temperature, duration of fever and day of rash onset between roseola infantum with and without febrile convulsions ( P > 0.05 ), but the frequency of family history of febrile convulsions was significantly higher in roseola infantum with febrile convulsions than in those without febrile convulsions ( P 0.05),而热性惊厥家族史有显著差别(P<0.05).结论 遗传因素是导致幼儿急疹并热性惊厥发作的一个危险因素;幼儿急疹并热性惊厥时一般预后良好,但要警惕发生严重中枢神经系统损伤的可能性,如癫痫.对于1岁内初次发热并出现热性惊厥的患儿要注意幼儿急疹的可能.

    The pathophysiology of febrile convulsion, the most common childhood neurologic disease, remains unclear. In this study, we investigated what role a heat shock protein plays in this disease. We enrolled eight boys and two girls with febrile convulsion and 10 age-matched healthy controls. We did a biosynthetic evaluation of both groups by separating lymphocytes and measuring the expression of heat shock protein 72 before and after heat shock treatment. Before the treatment, both groups were found to have small amounts of constitutive heat shock protein 72. Afterwards, its expression increased in both groups, and no statistical difference was found between the increases in the two groups. In addition, there was no obvious difference in the susceptibility to produce heat shock proteins. However, the febrile convulsion group was found to have a significant decrease in phosphorylation of heat shock protein 72. These results suggest the possible involvement of post-translational modification of heat shock proteins, most likely phosphorylation, in the pathogenesis of febrile convulsion. PMID:15875434

Materials and Methods In a controlled cross sectional study, 90 patients aged 9 months to 5 years were studied in a period of 12 months. They were assigned to three groups. Thirty patients were included in the Febrile Seizure group, thirty febrile children without convulsion or previous history of convulsion were included in the febrile group and thirty afebrile healthy ones were enrolled as controls. Venous blood was obtained and Zn concentration in serum was measured using Graphite Furnance Atomic Absorbance Spectrophotometering (GF-AAS. Results Patients and the control groups had no difference in either mean age or sex distribution. No significant relationship was observed between serum Zn level and age or sex among patients in the FC group and two other control groups. Conclusion Our findings showed that Zinc level was significantly lower in the febrile seizure group compared to two other groups. We tried to categorize various conditions in a more practical form. Also, Zinc is in close relationship with socioeconomic level of the individuals which was well considered in the current survey.

    The aim of this prospective study was to determine in a population of pediatric patients with febrile convulsions the prevalence and pattern of orofacial and dental injuries caused by traditional remedies used in a suburban Nigerian community. Over the study period of 28 months, 75 cases of febrile convulsion presented to the Children's Emergency unit of our hospital. Of these, 27 children (36%) sustained orofacial injuries caused by forceful insertion of a spoon into the mouth (96.3%) or a bite (3.7%) during convulsive episodes. The ages of the patients ranged from 12 to 84 months with a mean 39.8 +/- 18.3 months. There were 15 males and 11 females with a male to female ratio of 1.4:1. The orofacial and dental injuries sustained from prehospital treatment at home were lacerations and bruising of soft tissues including lips, tongue, mucosa and commissures and tooth subluxation, displacement or avulsion. Other injuries sustained outside the mouth include second-degree burns to the feet, a chin laceration and facial bruises resulting from a fall. Many oral injuries were overlooked by pediatricians. Prompt recognition and appropriate management of febrile convulsion would be of great benefit to the pediatric patients. PMID:17367452

They were followed for 1.6 years to 15 years (mean: 6.8 years) after the initial febrile convulsion. The incidence of subsequent epilepsy (two or more afebrile seizures) was 39%, and 80% of them developed epilepsy within 2 years after the first febrile convulsion. The paroxysmal discharges on EEG recorded prior to or after the first febrile convulsion did not predict the occurrence of later epilepsy. Also under 3 years of age, EEG findings led to the same result. There was no definite evidence that administration of anticonvulsive drugs prevented later epilepsy. Pre-existing neurological abnormality was identified as a risk factor for epilepsy, and was an indication of persistent medication. There is no clear prophylactic procedure against long-lasting attacks. Accordingly, medical therapy can be started when epilepsy has developed. Patients with very severe brain damage who could not move except lying comprised only 6% of all cases, and 69% of the epilepsy patients were well controlled. They showed a good prognosis as compared with children with brain-damage in general with epilepsy. PMID:9146028

  3. Anticonvulsant treatment of sarin-induced seizures with nasal midazolam: An electrographic, behavioral, and histological study in freely moving rats

    International Nuclear Information System (INIS)

    Centrally mediated seizures and convulsions are common consequences of exposure to organophosphates (OPs). These seizures rapidly progress to status epilepticus (SE) and contribute to profound brain injury. Effective management of these seizures is critical for minimization of brain damage. Nasal application of midazolam (1.5 mg/kg) after 5 min of sarin-induced electrographic seizure activity (EGSA) ameliorated EGSA and convulsive behavior (238 ± 90 s). Identical treatment after 30 min was not sufficient to ameliorate ECoG paradoxical activity and convulsive behavior. Nasal midazolam (1.5 mg/kg), together with scopolamine (1 mg/kg, im) after 5 min of EGSA, exerted a powerful and rapid anticonvulsant effect (53 ± 10 s). Delaying the same treatment to 30 min of EGSA leads to attenuation of paroxysmal ECoG activity in all cases but total cessation of paroxysmal activity was not observed in most animals tested. Cognitive tests utilizing the Morris Water Maze demonstrated that nasal midazolam alone or together with scopolamine (im), administered after 5 min of convulsions, abolished the effect of sarin on learning. Both these treatments, when given after 30 min of convulsions, only decreased the sarin-induced learning impairments. Whereas rats which were not subject to the anticonvulsant agents did not show any memory for the platform location, both treatments (at 5 min as well as at 30 min) completely abolished the memory deficits. Both treatments equally blocked the impairment of reversal learning when given at 5 min. However, when administered after 30 min, midazolam alone reversed the impairments in reversal learning, while midazolam with scopolamine did not. Rats exposed to sarin and treated with the therapeutic regimen with the exclusion of midazolam exhibited severe brain lesions that encountered the hippocampus, pyriform cortex, and thalamus. Nasal midazolam at 5 min prevented brain damage, while delaying the midazolam treatment to 30 min of EGSA resulted in

    Cerebrospinal fluid (CSF) was analysed to determine a lumbar puncture (LP) yield for meningitis in 95 children who presented with their first febrile convulsions between July 1993 and June 1994. There were 52 males and 43 females aged six months to six years with a mean age of 21.9 +/- 13.0 months at presentation. 87(91.6%) had simple febrile convulsions (SFC) while the remaining 8(8.4%) had complex febrile convulsions (CFC). The majority of the subjects presented with a sudden onset of convulsions that were preceded by a day or two history of fever, coryza, cough and respiratory distress while others had their convulsions preceded by fever and passage of bloody stools. The LP yield for meningitis in this series was 6.3%. The CSF analysis revealed six cases of meningitis comprising an eight month old infant with Haemophilus influenzae type B (HIB) meningitis, two partially treated pyogenic meningitis and three aseptic meningitis. All of them had presented with febrile convulsions without signs of meningeal irritation. Excluding aseptic meningitis from this series, a 3.1% LP yield for pyogenic meningitis is significant enough to recommend continued performance of LP in children with first febrile convulsions, especially if under the age of eighteen months.

    Full Text Available Abstract Introduction Non-convulsive status epilepticus is a form of epileptic seizure that occurs without convulsions. Recent reviews suggest that the diagnosis of non-convulsive status epilepticus remains difficult. Here, we report the case of a patient with thyroid-stimulating hormone elevation misdiagnosed as subclinical hypothyroidism following non-convulsive status epilepticus. Case presentation Our patient was a 68-year-old Japanese woman. The results of endocrine testing after her first episode of non-convulsive status epilepticus suggested latent subclinical hypothyroidism: she had elevated thyroid-stimulating hormone with normal levels of free tri-iodothyronine and free thyroxine. On examination, a diagnosis of thyroid disorder was not supported by other test results and our patient remained untreated. A follow-up examination revealed that her thyroid-stimulating hormone levels had spontaneously normalized. When she consulted another doctor for confusion, the transient increase in thyroid-stimulating hormone levels following non-convulsive status epilepticus was mistaken for subclinical hypothyroidism, and unfortunately treated with levothyroxine. Our patient then experienced levothyroxine-induced non-convulsive status epilepticus. Conclusions In this report, we suggested possible mechanisms for latent hypothyroid-like hormone abnormality following epileptic seizures and the possibility of provoking epileptic seizures by administering levothyroxine for misdiagnosed subclinical hypothyroidism.

    Full Text Available Objective  Febrile convulsion (FC is a common cause of seizure in young children, with an excellent prognosis. In addition to genetic predisposition and infections,FCs are generally thought to be induced by metabolic and elemental changes during fever such as Zinc (Zn deficiency. Regarding the high prevalence of febrile convulsions and the role of Zn deficiency, we investigated the role of Zn in FC patients in Isfahan, Iran.  Materials and Methods  In a controlled cross sectional study, 90 patients aged 9 months to 5 years were studied in a period of 12 months. They were assigned to three groups. Thirty patients were included in the Febrile Seizure group, thirty febrile children without convulsion or previous history of convulsion were included in the febrile group and thirty afebrile healthy ones were enrolled as controls. Venous blood was obtained and Zn concentration in serum was measured using Graphite Furnance Atomic Absorbance Spectrophotometering (GF-AAS.  Results  Patients and the control groups had no difference in either mean age or sex distribution. No significant relationship was observed between serum Zn level and age or sex among patients in the FC group and two other control groups.   Conclusion  Our findings showed that Zinc level was significantly lower in the febrile seizure group compared to two other groups. We tried to categorize various conditions in a more practical form. Also, Zinc is in close relationship with socioeconomic level of the individuals which was well considered in the current survey.  Keywords: Zinc; Zinc deficiency; Febrile Convulsion.

    2016-07-01

    The favorable consequences of environmental enrichment (EE) on brain and behavior development are well documented. Much less is known, however, about transgenerational benefits of EE on non-enriched offspring. We explored whether transgenerational effects of EE might extend to the development of repetitive motor behaviors in deer mice. Repetitive motor behaviors are invariant patterns of movement that, across species, can be reduced by EE. We found that EE not only attenuated the development of repetitive behavior in dams, but also in their non-enriched offspring. Moreover, maternal behavior did not seem to mediate the transgenerational effect we found, although repetitive behavior was affected by reproductive experience. These data support a beneficial transgenerational effect of EE on repetitive behavior development and suggest a novel benefit of reproductive experience. PMID:27059336

    [Objective] To explore the temperament characteristics of children from 3 to 7 years old with febrile convulsions. [Methods] 72 cases aged from 3 to 7 years were chosen with febrile convulsions in the 3rd affiliated hospital and 72 children in control group. Children 3~7 years old temperament questionnaire (Behavioral Style Questionnaire) and self-made questionnaire were filled in by their patients. [Results] The two groups had the same temperament types distribution (P>0. 05) and cases with febrile convulsions had more higher values than the control group in activity level, adaptability, intensity of reaction, quality of mood(P<0.05). And child with complex febrile convulsions often had temperament of difficult to raise, difficulties to raise in the middle type and slow-to-warm-up. The reaction intensity of temperament dimensions were the risk factors to recurrent febrile convulsions (P<0. 05) by multivariate analysis. [Conclusion] The assessment of temperament provides a new prevention and treatment ideas in children with febrile convulsions.%[目的]探讨3~7岁热惊厥儿童的气质特点,为临床有效诊治提供新的参考.[方法]选择本院3~7岁热惊厥发作以及对照组儿童各72例,采用3~7岁儿童气质问卷以及自制调查问卷进行调查.[结果]热惊厥儿童与正常对照组儿童气质类型大致相同(P>0.05);热惊厥儿童活动水平、适应性、反应强度、心境、持久性几个方面气质维度值高于对照组(P<0.05);复杂型热惊厥儿童气质类型中难养型、中间难养型以及启动缓慢型所占比例较高(P<0.05);多因素分析结果发现,气质维度中反应强度是本组热惊厥反复发作的高危因素(P<0.05).[结论]气质评估为热惊厥患儿提供了新的预防及治疗思路.

  12. Effects of prosocial video games on prosocial behavior.

    Science.gov (United States)

    Greitemeyer, Tobias; Osswald, Silvia

    2010-02-01

    Previous research has documented that playing violent video games has various negative effects on social behavior in that it causes an increase in aggressive behavior and a decrease in prosocial behavior. In contrast, there has been much less evidence on the effects of prosocial video games. In the present research, 4 experiments examined the hypothesis that playing a prosocial (relative to a neutral) video game increases helping behavior. In fact, participants who had played a prosocial video game were more likely to help after a mishap, were more willing (and devoted more time) to assist in further experiments, and intervened more often in a harassment situation. Results further showed that exposure to prosocial video games activated the accessibility of prosocial thoughts, which in turn promoted prosocial behavior. Thus, depending on the content of the video game, playing video games not only has negative effects on social behavior but has positive effects as well. PMID:20085396

    This study examined how environmental change and others' behavior affected cooperative behavior and solution preference of the person in social dilemma situation. Participants in two experiments played an "environment game," in which gradual pollution in environment and reduction in profit rate were simulated. Information on behavior of other players was manipulated: in "free rider" condition, one person was an extreme free rider, and the others were cooperative; in "loafing" condition, everyone loafed. In both experiments, "Bad Apple Effect" was not observed clearly, and cooperative behavior increased as environmental pollution worsened. In Experiment 2, there was no main effect of others' behavior on solution preference. However, significant correlations were found among solution preference, motivation to control others' behavior, and perceived seriousness of the situation, only when an extreme free rider was among them.

    Stereospermum kunthianum, Cham Sandrine Petit (Bignoniaceae) known in English as pink jacaranda is used in traditional medicine to treat an array of ailments including febrile convulsions in infants and young children by the rural dwellers in Nigeria. This study examined the anticonvulsant activity of its aqueous stem bark extract (100 - 400mg/kg) against maximal electroshock and pentylenetetrazole-induced seizures in rodents. Phenobarbitone and ethosuximide were used as reference anticonvulsant drugs for comparison. Stereospermum kunthianum extract (200 - 400mg/kg, i.p.) remarkably protected (76.9% and 84.6 % respectively) the rats against electroshock-induced seizures. However, the extract (200- 400mg/kg) when administered orally showed a comparatively less effect (33.3% and 55.6% respectively) to the intraperitoneally administered extract in the maximal electroshock test. The extract (100-400mg/kg, i.p.) significantly delayed (pmice. Although the findings in the present study do not provide conclusive evidence, it appears that the aqueous stem bark extract of Stereospermum kunthianum produces its antiseizure effect by enhancing GABAergic neurotransmission and/or action in the brain. The results indicate that the aqueous extract possesses anticonvulsant activity in rodents and therefore tend to suggest that the shrub may be used as a natural supplementary remedy in the management, control and/or treatment of childhood convulsions. It can be concluded that the aqueous stem bark extract possesses anticonvulsant activity and therefore lend pharmacological credence to the traditionally claimed use in the treatment of childhood convulsions.

    2012-05-01

    Full Text Available Abstract Background Acceptability is a poorly conceptualized dimension of access to health care. Using a study on childhood convulsion in rural Tanzania, we examined social acceptability from a user perspective. The study design is based on the premise that a match between health providers’ and clients’ understanding of disease is an important dimension of social acceptability, especially in trans-cultural communication, for example if childhood convulsions are not linked with malaria and local treatment practices are mostly preferred. The study was linked to health interventions with the objective of bridging the gap between local and biomedical understanding of convulsions. Methods The study combined classical ethnography with the cultural epidemiology approach using EMIC (Explanatory Model Interview Catalogue tool. EMIC interviews were conducted in a 2007/08 convulsion study (n = 88 and results were compared with those of an earlier 2004/06 convulsion study (n = 135. Earlier studies on convulsion in the area were also examined to explore longer-term changes in treatment practices. Results The match between local and biomedical understanding of convulsions was already high in the 2004/06 study. Specific improvements were noted in form of (1 46% point increase among those who reported use of mosquito nets to prevent convulsion (2 13% point decrease among caregivers who associated convulsion with ‘evil eye and sorcery’, 3 14% point increase in prompt use of health facility and 416% point decrease among those who did not use health facility at all. Such changes can be partly attributed to interventions which explicitly aimed at increasing the match between local and biomedical understanding of malaria. Caregivers, mostly mothers, did not seek advice on where to take an ill child. This indicates that treatment at health facility has become socially acceptable for severe febrile with convulsion. Conclusion As an important dimension

    Acute encephalopathy with febrile convulsive status epilepticus (AEFCSE) is the most common type of acute encephalopathy in childhood in Japan, which develops with prolonged febrile convulsion, followed by mild unconsciousness. It is generally sporadic and nonrecurrent. In this report, a 1-year-old girl showed signs of AEFCSE triggered by respiratory syncytial virus infection. Two years later, she presented with AEFCSE triggered by influenza virus infection, resulting in severe neurologic sequelae. The patient had a thermolabile genotype of carnitine palmitoyltransferase II (CPT II) variations consisting of three single nucleotide polymorphisms in exons 4 [1055T > G/F352C and 1102G > A/V368I] and 5 [1939A > G/M647V]. The polymorphism has been identified as a genetic predisposition for acute encephalopathy. This report presents the first case of recurrent encephalopathy with CPT II variations that may partially associate with pathogenesis of recurrent AEFCSE. PMID:23450341

    Considering the fact, in the real world, that information is transmitted with a time delay, we study an evolutionary spatial prisoner's dilemma game where agents update strategies according to certain information that they have learned. In our study, the game dynamics are classified by the modes of information learning as well as game interaction, and four different combinations, i.e. the mean-field case, case I, case II and local case, are studied comparatively. It is found that the time delay in case II smoothes the phase transition from the absorbing states of C (or D) to their mixing state, and promotes cooperation for most parameter values. Our work provides insights into the temporal behavior of information and the memory of the system, and may be helpful in understanding the cooperative behavior induced by the time delay in social and biological systems.

    Over the past decades, it has become clear that the most efficient way to prevent status epilepticus is to stop the seizure as fast as possible, and early treatment of prolonged convulsive seizures has become an integral part of the overall treatment strategy in epilepsy. Benzodiazepines are the first choice drugs to be used as emergency medication. This treatment in the early phases of a seizure often implies a 'pre-medical' setting before intervention of medically trained persons. In this p...

    Serum immunoglobulin levels of 86 epileptic patients have been evaluated in order to investigate the relationship between epilepsy, antiepileptic drugs and humoral immunity. The results confirm a high incidence of immunological disorders in the epileptic and febrile convulsion patients. These abnormalities were not related to clinical type of epilepsy nor to the therapy; the common feature seems the early onset of seizures and antiepileptic treatment. PMID:6791931

    Full Text Available Abstract Introduction Hepatic encephalopathy is usually suspected in patients who are cirrhotic with neuropsychiatric manifestations. We present a case of suspected hepatic encephalopathy that did not respond to standard empiric therapy and was eventually diagnosed as non-convulsive status epilepticus of complex partial type. Our patient responded dramatically to anti-convulsive therapy. Case presentation We report the case of a 45-year-old African-American man with hepatitis C virus cirrhosis and human immunodeficiency virus who presented to our facility with a one-day history of confusion and a variable mental status. Our patient’s vital signs were stable and all his electrolytes were within normal range. A clinical diagnosis of hepatic encephalopathy was made and our patient was started on empiric therapy with lactulose and rifaximin. Our patient did not respond to therapy. After five days of treatment, alternative diagnoses were sought and a neurology consult was requested. An electroencephalogram was eventually performed which showed seizure activity in the right parietal lobe. A diagnosis of non-convulsive status epilepticus was made and our patient was started on oral levetiracetam. On day two of therapy, our patient was alert and oriented. He continues to do well on follow-up approximately one year after discharge. Conclusions Non-convulsive status epilepticus should be considered in the differential diagnosis of patients with suspected hepatic encephalopathy who do not respond to empirical treatment. Further studies are needed to investigate the incidence of this entity in patients with persistent hepatic encephalopathy.

  1. Incentives for cost-effective physician behavior.

    Science.gov (United States)

    Maynard, A

    1987-04-01

    The objective of the National Health Service is to maximise improvements in the health status of patients regardless of their willingness and ability to pay. To achieve this objective it is necessary to identify those procedures which maximise improvements in health or quality adjusted life years (QALYs) and direct scarce resources to those therapies with the best cost-QALY characteristics. Unfortunately in the NHS and elsewhere cost-QALY characteristics are largely unknown and the structure of the health service and its provider remuneration systems are such that objectives are vague, behavior perverse due to the haphazard construction of incentive systems, and health status outcomes often unknown due to the failure to evaluate input-outcome relationships. To reform the NHS, in particular ensure more efficient practice by physicians, existing perverse incentives will have to be replaced by the use of buyer (NHS) power and by budgeting mechanisms which induce economizing behavior. It is not clear which type of incentive mechanism will produce outcomes consistent with NHS goals. To remedy this ignorance experimentation with careful evaluation would seem appropriate.

    We studied the efficacy and safety of midazolam given as a continuous infusion in the treatment of refractory generalized convulsive status epilepticus (RGCSE). We carried out a prospective, open study, in 19 patients (11 men) with RGCSE in the intensive care unit at Firat Medical Center in Elazig. When intravenous administration of 0.3 mg/kg diazepam (three times at 5-min intervals), 20 mg/kg phenytoin, and 20 mg/kg phenobarbital failed to bring the episode under control, patients were administered an intravenous bolus of midazolam (200 microg/kg) followed by a continuous infusion at 1 microg/kg min. The dose was increased by 1 microg/kg min every 15 min until the episode of seizure was brought under control. The time from beginning of treatment to control of seizures, infusion rate, and side-effects were monitored. The mean age of the patients was 40.4 years (range 16-87 years). The clinical etiology of RGCSE was idiopathic epilepsy (6 cases), anoxicischemic cerebral insult due to cardiac arrest (3), viral encephalitis (2), intrahemispheric hematoma due to hemorrhagic stroke (1), cerebral infarct due to ischemic stroke (1), pituitary adenoma (1), post-traumatic epilepsy (1), renal failure (1), tuberculous meningitis (1), and unknown (2). In eighteen (94.7%) patients, seizures were completely controlled in a mean time of 45 min (range, 5-120 min) at a mean infusion rate of 8 microg/kg min (range, 3-21 microg/kg min). In one patient seizures did not stop. Midazolam administration did not cause any significant change in blood pressure, heart rate, oxygen saturation, or respiratory status. The mean time to full consciousness for patients after stopping the infusion was 1.6 hours (range, 2.0-8.5 hours). The mean infusion duration of midazolam was 14.5 hours (range, 12-25 hours). Midazolam is an effective and safe drug to control RGCSE, and may represent a substantial improvement over current therapeutic approaches such as pentobarbital anesthesia. PMID:12536286

    2010-11-01

    Full Text Available Abstract Background The widespread incorporation of behavioral support interventions into exercise trials has sometimes caused confusion concerning the primary purpose of a trial. The purpose of the present paper is to offer some conceptual and methodological distinctions among three types of exercise trials with a view towards improving their design, conduct, reporting, and interpretation. Discussion Exercise trials can be divided into "health outcome trials" or "behavior change trials" based on their primary outcome. Health outcome trials can be further divided into efficacy and effectiveness trials based on their potential for dissemination into practice. Exercise efficacy trials may achieve high levels of exercise adherence by supervising the exercise over a short intervention period ("traditional" exercise efficacy trials or by the adoption of an extensive behavioral support intervention designed to accommodate unsupervised exercise and/or an extended intervention period ("contemporary" exercise efficacy trials. Exercise effectiveness trials may emanate from the desire to test exercise interventions with proven efficacy ("traditional" exercise effectiveness trials or the desire to test behavioral support interventions with proven feasibility ("contemporary" exercise effectiveness trials. Efficacy, effectiveness, and behavior change trials often differ in terms of their primary and secondary outcomes, theoretical models adopted, selection of participants, nature of the exercise and comparison interventions, nature of the behavioral support intervention, sample size calculation, and interpretation of trial results. Summary Exercise researchers are encouraged to clarify the primary purpose of their trial to facilitate its design, conduct, and interpretation.

  13. Adaptive Controller Effects on Pilot Behavior

    Science.gov (United States)

    Trujillo, Anna C.; Gregory, Irene M.; Hempley, Lucas E.

    2014-01-01

    Adaptive control provides robustness and resilience for highly uncertain, and potentially unpredictable, flight dynamics characteristic. Some of the recent flight experiences of pilot-in-the-loop with an adaptive controller have exhibited unpredicted interactions. In retrospect, this is not surprising once it is realized that there are now two adaptive controllers interacting, the software adaptive control system and the pilot. An experiment was conducted to categorize these interactions on the pilot with an adaptive controller during control surface failures. One of the objectives of this experiment was to determine how the adaptation time of the controller affects pilots. The pitch and roll errors, and stick input increased for increasing adaptation time and during the segment when the adaptive controller was adapting. Not surprisingly, altitude, cross track and angle deviations, and vertical velocity also increase during the failure and then slowly return to pre-failure levels. Subjects may change their behavior even as an adaptive controller is adapting with additional stick inputs. Therefore, the adaptive controller should adapt as fast as possible to minimize flight track errors. This will minimize undesirable interactions between the pilot and the adaptive controller and maintain maneuvering precision.

  14. Effect of DC voltage pulses on memristor behavior.

    2013-10-01

    Current knowledge of memristor behavior is limited to a few physical models of which little comprehensive data collection has taken place. The purpose of this research is to collect data in search of exploitable memristor behavior by designing and implementing tests on a HP Labs Rev2 Memristor Test Board. The results are then graphed in their optimal format for conceptualizing behavioral patterns. This series of experiments has concluded the existence of an additional memristor state affecting the behavior of memristors when pulsed with positively polarized DC voltages. This effect has been observed across multiple memristors and data sets. The following pages outline the process that led to the hypothetical existence and eventual proof of this additional state of memristor behavior.

  15. Effects of switching behavior for the attraction on pedestrian dynamics

    Kwak, Jaeyoung; Luttinen, Tapio; Kosonen, Iisakki

    2014-01-01

    Walking is a fundamental activity of our daily life not only for moving to other places but also for interacting with surrounding environment. While walking on the streets, pedestrians can be aware of attractions like shopping windows. They can be influenced by the attractions and some of them might shift their attention towards the attractions, namely switching behavior. As a first step to incorporate the switching behavior, this study investigates collective effects of switching behavior for an attraction by developing a behavioral model. Numerical simulations exhibit different patterns of pedestrian behavior depending on the strength of the social influence and the average length of stay. When the social influence is strong along with a long length of stay, a saturated phase can be defined at which all the pedestrians have visited the attraction. If the social influence is not strong enough, an unsaturated phase appears where one can observe that some pedestrians head for the attraction while others walk i...

    Full Text Available Recent empirical evidence shows that working in an unsupervised, isolated situation under competition, can increase dishonest behavior to achieve prestige. However, could working in a common space, in the presence of colleagues affect cheating? Here, we examine how familiar-peer influence, supervision and social incentives affect worker performance and dishonest behavior. First, we show that working in the presence of peers is an effective mechanism to constrain honest/dishonest behavior compared to an isolated work situation (experiment 1. Second, we demonstrate that the mere suspicion of dishonesty from another peer is not enough to affect individual cheating behavior (experiment 2, suggesting that reputation holds great importance in a worker's self-image acting as a strong social incentives. Third, we show that when the suspicion of dishonesty increases with multiple peers behaving dishonestly, the desire to increase standing is sufficient to nudge individuals' behavior back to cheating at the same levels as isolated situations (experiment 3.

    Polymeric materials usually present some viscoelastic behavior. To improve the mechanical behavior of these materials, ceramics materials are often filled into the polymeric materials in form of fiber or particle. A micromechanical model was proposed to estimate the overall viscoelastic behavior for particulate polymer composites, especially for high volume concentration of filled particles. The method is based on Laplace transform technique and an elastic model including two-particle interaction. The effective creep compliance and the stress and strainrelation at a constant loading rate are analyzed. The results show that the proposed method predicts a significant stiffer response than those based on Mori-Tanaka's method at high volume concentration of particles.

    Full Text Available There are few studies on the pharmacological properties of Valeriana prionophylla Standl. (VP, known as “Valeriana del monte”, and used in Mesoamerican folk medicine to treat sleep disorders. This study examines the pharmacological effects of the hydroalcoholic extract of the dry rhizome using the open field, rota rod, elevated plus-maze (EPM, forced swimming (FST, strychnine- and pentobarbital-induced sleeping time, PTZ-induced seizures, and the inhibitory avoidance tests. VP did not show any protective effect against PTZ-induced convulsions. In the EPM, exhibited an anxiolytic-like effect through the effective enhancement of the entries (38.5% and time spent (44.7% in the open arms, when compared with control group. Time spent and the numbers of entrances into the enclosed arms were decreased, similar to those effects observed with diazepam. In the FST, acute treatment with VP, produced a dose-dependent decrease in immobility time, similarly to imipramine. VP also produced a significant dose-dependent decrease in the latency of sleeping time, while producing an increase in total duration of sleep; influenced memory consolidation of the animals only at lower doses, unlike those that produced anti-depressant and anxiolytic effects. In summary, the results suggest that VP presents several psychopharmacological activities, including anxiolytic, antidepressant, and hypno-sedative effects.

    We examine the effect of adherence to behavioral codes, as measured by the degree of religiosity, on the level of honesty by conducting under-the-cup die experiments. The findings suggest that behavioral codes, which prohibit lying, offset the monetary incentive to lie. The highest level of honesty is found among young religious females while the lowest is found among secular females. Moreover, when the monetary incentive to lie is removed, the tendency of secular subjects to lie disappears. ...

    Full Text Available Epilepsy is one of the most common neurological conditions globally, estimated to constitute 0.75% of the global burden of disease, with the majority of this burden found in low- and middle- income countries (LMICs. Few studies from LMICs, including much of sub-Saharan Africa, have described the incidence, remission or mortality rates due to epilepsy, which are needed to quantify the burden and inform policy. This study investigates the epidemiological parameters of convulsive epilepsy within a context of high HIV prevalence and an emerging burden of cardiovascular disease.A cross-sectional population survey of 82,818 individuals, in the Agincourt Health and Socio-demographic Surveillance Site (HDSS in rural northeast South Africa was conducted in 2008, from which 296 people were identified with active convulsive epilepsy. A follow-up survey was conducted in 2012. Incidence and mortality rates were estimated, with duration and remission rates calculated using the DISMOD II software package.The crude incidence for convulsive epilepsy was 17.4/100,000 per year (95%CI: 13.1-23.0. Remission was 4.6% and 3.9% per year for males and females, respectively. The standardized mortality ratio was 2.6 (95%CI: 1.7-3.5, with 33.3% of deaths directly related to epilepsy. Mortality was higher in men than women (adjusted rate ratio (aRR 2.6 (95%CI: 1.2-5.4, and was significantly associated with older ages (50+ years versus those 0-5 years old (RR 4.8 (95%CI: 0.6-36.4.The crude incidence was lower whilst mortality rates were similar to other African studies; however, this study found higher mortality amongst older males. Efforts aimed at further understanding what causes epilepsy in older people and developing interventions to reduce prolonged seizures are likely to reduce the overall burden of ACE in rural South Africa.

    Full Text Available It is difficult to diagnose non-convulsive status epilepticus (NCSE clinically because of the complicated etiology and various clinical and electroencephalographic features of NCSE without a universally accepted definition. Although the diagnosis of NCSE relies largely on electroencephalogram (EEG findings, the determination of NCSE on EEG is inevitably subjective, and the EEG changes of most patients is lack of specificity. As the diagnosis of NCSE is related to clinical and electroencephalographic manifestations, diagnostic criteria for NCSE should take into account both clinical and electroencephalographic features, and their response to antiepileptic drugs (AEDs. DOI: 10.3969/j.issn.1672-6731.2015.11.005

    Exposing rats to an upshift from a small reward to a larger reward sometimes yields evidence of consummatory successive positive contrast (cSPC), an effect that could be a suitable animal model of positive emotion. However, cSPC is an unreliable effect. Ten experiments explored the effects of an upshift in sucrose or saccharin concentration on consummatory behavior under several conditions. There was occasional evidence of cSPC, but mostly a combination of increased consummatory behavior relative to preshift reward concentrations and a reduced behavioral level relative to unshifted controls. Such a pattern is consistent with processes causing opposite changes on behavior. Reward upshift may induce processes that suppress behavior, such as taste neophobia (induced by an intense sucrose taste) and generalization decrement (induced by novelty in reward conditions after the upshift). An experiment tested the role of such novelty-related effects by preexposing animals to either the upshift concentration (12% sucrose) or water during three days before the start of the experiment. Sucrose-preexposed animals drank significantly more than water-preexposed animals during the upshift, but just as much as unshifted controls (i.e., no evidence of cSPC). These results suggest that cSPC may be difficult to obtain reliably because reward upshift induces opposing processes. However, they also seriously question the ontological status of cSPC.

  18. Effects of guest feeding programs on captive giraffe behavior.

    2016-01-01

    Zoological institutions develop human-animal interaction opportunities for visitors to advance missions of conservation, education, and recreation; however, the animal welfare implications largely have yet to be evaluated. This behavioral study was the first to quantify impacts of guest feeding programs on captive giraffe behavior and welfare, by documenting giraffe time budgets that included both normal and stereotypic behaviors. Thirty giraffes from nine zoos (six zoos with varying guest feeding programs and three without) were observed using both instantaneous scan sampling and continuous behavioral sampling techniques. All data were collected during summer 2012 and analyzed using linear mixed models. The degree of individual giraffe participation in guest feeding programs was positively associated with increased time spent idle and marginally associated with reduced time spent ruminating. Time spent participating in guest feeding programs had no effect on performance of stereotypic behaviors. When time spent eating routine diets was combined with time spent participating in guest feeding programs, individuals that spent more time engaged in total feeding behaviors tended to perform less oral stereotypic behavior such as object-licking and tongue-rolling. By extending foraging time and complexity, guest feeding programs have the potential to act as environmental enrichment and alleviate unfulfilled foraging motivations that may underlie oral stereotypic behaviors observed in many captive giraffes. However, management strategies may need to be adjusted to mitigate idleness and other program consequences. Further studies, especially pre-and-post-program implementation comparisons, are needed to better understand the influence of human-animal interactions on zoo animal behavior and welfare.

  19. Behavioral effects of nerve agents: laboratory animal models

    International Nuclear Information System (INIS)

    Diverse and often subtle behavioral consequences have been reported for humans exposed to nerve agents. Laboratory studies of nerve agent exposure offer rigorous control over important variables, but species other than man must be used. Nonhuman primate models offer the best means of identifying the toxic nervous system effects of nerve agent insult and the countermeasures best capable of preventing or attenuating these effects. Comprehensive behavioral models must evaluate preservation and recovery of function as well as new learning ability. The throughput and sensitivity of the tests chosen are important considerations. A few nonhuman primate studies will be discussed to elaborate recent successes, current limitations, and future directions.(author)

    The dynamic behavior of Multiwall boron nitride nanotubes (MWBNNTs) is investigated by employing multiple elastic shells model. The influences of van der Waals interactions on layers are shown as nonlinear functions of the interlayer distance of MWBNNTs. Governing equations are solved by using the developed finite element method and by employing time history diagrams. The radial wave speed from the outermost layer to the innermost layer is computed. The effects of geometrical factors such as diameter-to-thickness ratio on dynamic behavior of MWBNNTs are determined. The magnification aspects of MWBNNTs are computed, and the effects of surrounding pressures on wave speed and magnification aspect of MWBNNTs are discussed.

    Full Text Available ABSTRACT: Crotalphine is a novel analgesic peptide that acts on kappa opioid and delta receptors, causing powerful analgesia in rats submitted to inflammatory, neuropathic or oncologic models of pain. This study evaluated clinical, behavioral and antinociceptive effects caused by crotalphine in horses, employing 18 Arabian horses and it was divided in three phases. In Phase I, "clinical and behavioral effects", crotalphine did not change the latency to urinate and defecate; did not modify the values of cardiac or respiratory rates, intestinal motility and rectal temperature; and did not cause significant ataxia, head, eye and lip ptosis. In Phase II, "antinociceptive effect on intact skin at scapular or ischial region", crotalphine did not cause significant analgesia. In Phase III, "antinociceptive effect on incised skin at scapular or ischial region", crotalphine promoted effective antinociceptive effects for six hours and inhibited hyperalgesia state for three days in the ischial region of horses submitted to incisional model of inflammatory pain, but crotalphine did not evoke relevant analgesic effect on the scapular region. Concluding, intravenous injection of a single dose of crotalphine (3.8ngkg-1 did not cause important clinical or behavioral changes and promotes antinociceptive effect on incised ischial region for seven days in horses. Moreover, crotalphine did not evoke relevant anti nociceptive effect on the scapular region or in intact skin of horses.

    Full Text Available Background: In Iranian traditional medicine, Ferula assa-foetida oleo gum resin (asafoetida have been used as anti-convulsant agents. Aims: This study was designed to evaluate the anti-convulsant effect of asafoetida on chemical and amygdala -kindled rats. Materials and Methods: In chemical model, rats received orally asafoetida at dose of 50 and 100 mg/kg 90 minutes prior to Pentylenetetrazol injection in dose of 35 mg/kg intraperitoneally (i.p. and control group received normal saline. Convulsive behavior was recorded for 30 minutes. For amygdala kindle model, bipolar stimulating and monopolar recording electrodes were implanted stereotaxically. After kindling, the effect of asafoetida (50 and 100mg/kg on after discharge duration, duration of stage 5 seizure and latency to the onset of bilateral forelimb clonuses was measured. Results: Pretreatment animals with asafoetida significantly reduced the mean seizure stage during the 20 kindling injection of Pentylenetetrazol. Seizure parameters in amigdala kindle model improved in treatment animals at both dose 50 and 100 mg/kg. The number of stimulations in stage 3, 4, and 5 in asafoetida-treated rats at both doses significantly increased. Conclusions: These results showed that asafoetida could prevent seizure in both chemical and electrical kindling model and this effect may partially be related to the terpenoids compounds.

    Febrile convulsion (FC) is the most common seizure disorder in childhood. white blood cell (WBC) and erythrocyte sedimentation rate (ESR) are commonly measured in FC. Trauma, vomiting and bleeding can also lead to WBC and ESR so the blood tests must carefully be interpreted by the clinician. In this cross sectional study 410 children(163 with FC), aged 6 months to 5 years, admitted to Bahrami Children hospital in the first 48 hours of their febrile disease, either with or without seizure, were evaluated over an 18 months period. Age, sex, temperature; history of vomiting, bleeding or trauma; WBC, ESR and hemoglobin were recorded in all children. There was a significant increase of WBC (P<0.001) in children with FC so we can deduct that leukocytosis encountered in children with FC can be due to convulsion in itself. There was no significant difference regarding ESR (P=0.113) between the two groups. In fact, elevated ESR is a result of underlying pathology. In stable patients who don't have any indication of lumbar puncture, there's no need to assess WBC and ESR as an indicator of underlying infection. If the patient is transferred to pediatric ward and still there's no reason to suspect a bacterial infection, there is no need for WBC test. PMID:21960077

    2016-01-01

    Full Text Available Posterior reversible encephalopathy syndrome (PRES is associated with various clinical manifestations such as headache, blurred vision, confusion and tonic-clonic convulsion. Some of the predisposing factors for PRES include hypertensive encephalopathy, preeclampsia and eclampsia, lupus erythematosus, thrombotic thrombocytopenic purpura and long-term use of immunosuppressive drugs. This condition rarely occurs after normotensive and uneventful pregnancies. Several theories have been proposed on the etiology of PRES. For instance, endothelial injury and brain edema have been reported as possible causes of PRES. Although PRES is a temporary condition, proper and timely management of the disorder in the acute phase is critical for the prevention of permanent neurological complications. During pregnancy, PRES is normally accompanied with hypertension. In this paper, we present a rare case of PRES in a normotensive pregnancy in a 25-year-old parturient woman (Gravida 2, Ab 1. The patient unexpectedly manifested symptoms of tonic-clonic convulsion one hour after an uneventful vaginal delivery, which were successfully managed. According to our observations, PRES has various clinical manifestations with unexpected occurrence in some cases. Therefore, it is recommended that maternity centers be well-equipped with resuscitation tools, emergency drugs and expert staff so as to manage unforeseen PRES efficiently and prevent permanent maternal neurological complications and mortality.

    Full Text Available Introduction: With industrialization of human societies, pollutants like lead have entered in the life cycle, causing harmful effects on body organs. No sufficient studies have been done on the effects of pollutants on behavior. The aim of this study was to investigate possible effects of lead on some measurable behaviors of an animal model. Methods: Forty eight male adult mice were divided into 4 groups of 12 each. Lead acetate was added at concentrations of 0, 5, 50, or 500 ppm to the drinking water of the animals for 4 weeks (28 days. On day 29, animals were placed on an Elevated Plus maze (EPM for 5 min and the time in sec spent was measured on closed arms, open arms and the end 1/3rd of the open arms. Increased time on open arms, particularly the end 1/3rd was considered to reflect an enhanced risk-accepting behavior. Results: In this study, it was shown that lead exposure caused an increased number of entrance (P=0.006 and time spent (P=0.034 by mice on open arms of the EPM. There was a positive correlation between the concentration of lead acetate and those two effects. Conclusion: The present study demonstrated that lead poisoning may decrease normal anxiety in mice and increase risky behavior in this species. Clinical studies on human subjects with risky behavior are strongly suggested in order to find a possible relation between chronic exposures to lead as well as plasma concentration of lead with the extent of this kind of behavior.

    This paper explores the processes behind the neighborhood effect in electoral geography. Studies on neighborhood effect have largely ignored the local institutions and cultural milieu within which people are socialized. By taking into account the spatially differentiated social supervision of individuals, we are able to highlight the impact of local institutions on electoral behavior and restore the temporal dimension that has shaped the political specificities of places. In the case of Belgi...

    OpenAIRE

    Restagno, F.; Gayvallet, H.; Bocquet, L.; Charlaix, E.

    1999-01-01

    We present a study of humidity effects on the maximum stability angle in granular media. We show that a granular medium of small glass beads exhibits aging properties : the first avalanche angle increases logarithmically with the resting time of the pile. This aging behavior is found to depend on the relative humidity of the surrounding atmosphere. A short interpretation of this effect, based on a model of activated capillary condensation, is proposed.

    Full Text Available Objetivo: estudar a grande variação dos prognósticos relatados após a primeira crise convulsiva não provocada e dos fatores de risco que são associados com recorrência, estabelecendo uma conduta uniforme. Fontes dos dados: revisão sistemática das citações do banco de dados da Bireme. Síntese dos dados: a taxa de recorrência difere nos estudos de primeira crise em conseqüência dos diferentes critérios de inclusão. O eletrencefalograma (EEG é particularmente útil na determinação da natureza epiléptica de um evento nos pacientes mais jovens e naqueles com crises de origem desconhecida. Um EEG anormal, particularmente com descargas de ponta-onda generalizadas, tem sido relatado como um preditor de recorrência consistente. Embora não seja um substituto para o exame clínico, o EEG é parte integral do processo diagnóstico após a primeira crise afebril, e deve ser solicitado. A decisão quanto tratar ou não os pacientes que apresentaram uma crise única depende fortemente do conhecimento do médico da potencial morbidade de uma outra crise versus a potencial morbidade da terapia com drogas antiepilépticas (DAEs. Conclusões: em crianças, efeitos colaterais das DAEs são comuns, e o risco de injúria após uma crise geralmente é mínimo, já que elas não se expõem a situações de extremo risco, como a condução de automóveis ou a operação de máquinas, além do fato de geralmente estarem em ambiente supervisionado. Em adultos, esta unanimidade é pequena.Objective: to observe the wide variety of reported prognosis after a first unprovoked convulsion and of risk factors that are associated with recurrence, and a uniform conduct. Sources: systematic review of Bireme. Summary of the findings: recurrence rates differ from a first seizure study because of different inclusion criteria. The EEG is particularly helpful to support the epileptic nature of the event in younger patients and in those with seizures of unknown

    Cyclosporine, a calcineurin inhibitor, is successfully used as an immunosuppressant in transplant medicine. However, the use of this pharmaceutical during pregnancy is concerning since calcineurin is thought to play a role in neural development. The risk for human brain development is difficult to evaluate because of a lack of basic information on the sensitive developmental times and the potentially pleiotropic effects on brain development and behavior. In the present study, we use zebrafish as a model system to examine the effects of embryonic cyclosporine exposures. Early embryonic exposures reduced the size of the eyes and brain. Late embryonic exposures did not affect the size of the eyes or brain, but did lead to substantial behavioral defects at the larval stages. The cyclosporine-exposed larvae displayed a reduced avoidance response to visual stimuli, low swim speeds, increased resting, an increase in thigmotaxis, and changes in the average distance between larvae. Similar results were obtained with the calcineurin inhibitor FK506, suggesting that most, but not all, effects on brain development and behavior are mediated by calcineurin inhibition. Overall, the results show that cyclosporine can induce either structural or functional brain defects, depending on the exposure window. The observed functional brain defects highlight the importance of quantitative behavioral assays when evaluating the risk of developmental exposures. PMID:25591474

    Full Text Available Abstract Introduction Autism is complex neuro-developmental disorder which has a symptomatic diagnosis in patients characterized by disorders in language/communication, behavior, and social interactions. The exact causes for autism are largely unknown, but is has been speculated that immune and inflammatory responses, particularly those of Th2 type, may be involved. Thiazolidinediones (TZDs are agonists of the peroxisome proliferator activated receptor gamma (PPARγ, a nuclear hormone receptor which modulates insulin sensitivity, and have been shown to induce apoptosis in activated T-lymphocytes and exert anti-inflammatory effects in glial cells. The TZD pioglitazone (Actos is an FDA-approved PPARγ agonist used to treat type 2 diabetes, with a good safety profile, currently being tested in clinical trials of other neurological diseases including AD and MS. We therefore tested the safety and therapeutic potential of oral pioglitazone in a small cohort of children with diagnosed autism. Case description The rationale and risks of taking pioglitazone were explained to the parents, consent was obtained, and treatment was initiated at either 30 or 60 mg per day p.o. A total of 25 children (average age 7.9 ± 0.7 year old were enrolled. Safety was assessed by measurements of metabolic profiles and blood pressure; effects on behavioral symptoms were assessed by the Aberrant Behavior Checklist (ABC, which measures hyperactivity, inappropriate speech, irritability, lethargy, and stereotypy, done at baseline and after 3–4 months of treatment. Discussion and evaluation In a small cohort of autistic children, daily treatment with 30 or 60 mg p.o. pioglitazone for 3–4 months induced apparent clinical improvement without adverse events. There were no adverse effects noted and behavioral measurements revealed a significant decrease in 4 out of 5 subcategories (irritability, lethargy, stereotypy, and hyperactivity. Improved behaviors were inversely

    Convulsion is the medical condition where body muscles contract and relax rapidly and repeatedly,resulting in an uncontrolled shaking of the body.The impaired inhibition of electrical activity in the brain is one of leading causes of convulsion.y-aminobutyric acid (GABA) is the chief inhibitory neurotransmitter in the mammalian central nervous system (CNS).GABA acts at inhibitory synapses in the brain by binding to specific transmembrane receptors in the plasma membrane of both pre- and post-synaptic neuronal processes.GABAA receptor (GABAAR) is the most important inhibitory receptor,and is the target receptor of anticonvulsant drugs in the clinic.In this review,we describe GABAergic signaling mediated by GABAAR,the mechanisms of GABAAR and their expression,and the progress being made on understanding the role of GABAAR in convulsion with emphasis on the association between GABAAR mutations or GABAAR subunit expression and convulsion.We also describe progress of anticonvulsant drugs based on the GABAAR.

    Full Text Available Febrile convulsion is a common disorder in children. Viral infections such as human herpes virus 6 (HHV-6 which results in roseola infantum may contribute to developing seizure. The objective of this study was to determine the prevalence of HHV-6 by detecting DNA in cerebrospinal fluid (CSF of children with febrile convulsion and without any rash of roseola infantum.In this descriptive cross-sectional study, CSF of 100 children younger than 2 years of age with febrile convulsion was evaluated for detecting HHV-6 DNA by PCR. All of them were referred to emergency ward in Pediatric Medical Center from March 2010 to March 2011. General information, clinical manifestations, laboratory tests and outcomes were collected in the questionnaires.One hundred children including 59 males and 41 females were evaluated. HHV-6 was detected from CSF in six patients (6% by PCR. Mean age was 8 months old. All children were younger than 12 months old. The most common primary manifestation was fever alone. None of them had rash. Majority of cases occurred in winter. All patients recovered without any encephalitis.These findings showed that primary infection with HHV-6 is frequently associated with febrile convulsion in infants which may be at risk for subsequent development of epilepsy.

  6. On the effects of testosterone on brain behavioral functions

    2015-02-01

    Full Text Available Testosterone influences the brain via organizational and activational effects. Numerous relevant studies on rodents and a few on humans focusing on specific behavioral and cognitive parameters have been published. The results are, unfortunately, controversial and puzzling. Dosing, timing, even the application route seem to considerably affect the outcomes. In addition, the methods used for the assessment of psychometric parameters are a bit less than ideal regarding their validity and reproducibility. Metabolism of testosterone contributes to the complexity of its actions. Reduction to dihydrotestosterone by 5-alpha reductase increases the androgen activity; conversion to estradiol by aromatase converts the androgen to estrogen activity. Recently, the non-genomic effects of testosterone on behavior bypassing the nuclear receptors have attracted the interest of researchers. This review tries to summarize the current understanding of the complexity of the effects of testosterone on brain with special focus on their role in the known sex differences.

    We report ferromagnetic-like properties and exchange bias effect in akaganeite (β-FeOOH) nanorods. They exhibit a Néel temperature T{sub N} = 259 K and ferromagnetic-like hysteresis behavior both below and above T{sub N}. An exchange bias effect is observed below T{sub N} and represents an interesting behavior for akaganeite nanorods. These results are explained on the basis of a core-shell structure in which the core has bulk akaganeite magnetic properties (i.e., antiferromagnetic ordering) while the shell exhibits a disordered spin state. Thus, the nanorods show ferromagnetic properties and an exchange bias effect at the same time, increasing their potential for use in practical applications.

    If changes in animal behavior resulting from direct human disturbance negatively affect the persistence of a given species or population, then these behavioral changes must necessarily lead to reduced demographic performance. We tested for the effects of human disturbance on Olympic marmots (Marmota olympus), a large ground-dwelling squirrel that has disappeared from several areas where recreation levels are high. We assessed the degree to which antipredator and foraging behavior and demographic rates (survival and reproduction) differed between sites with high recreation levels (high use) and those with little or no recreation (low use). Compared with the marmots at low-use sites, marmots at high-use sites displayed significantly reduced responses to human approach, which could be construed as successful accommodation of disturbance or as a decrease in predator awareness. The marmots at high-use sites also looked up more often while foraging, which suggests an increased wariness. Marmots at both types of sites had comparable reproductive and survival rates and were in similar body condition. Until now, the supposition that marmots can adjust their behavior to avoid negative demographic consequences when confronted with heavy tourism has been based on potentially ambiguous behavioral data. Our results support this hypothesis in the case of Olympic marmots and demonstrate the importance of considering demographic data when evaluating the impacts of recreation on animal populations.

    Full Text Available Many studies have pointed out the importance of mother-child interaction in the early months of life. A few decades ago, a method called kangaroo care was developed and its main goal was to keep underweight or premature newborns in direct contact with the mother. This method has reduced the morbidity and mortality of these newborns, increasing their growth rate, breastfeeding time and mother-child contact. In rodents, the dam's presence is crucial for avoiding aggression factors that may trigger phenotypic adaptations in the pups with irreversible morphological, functional and behavioral consequences. Eating behavior is an adaptive response stemming from the external environment demand and modulated by opportunities and limitations imposed by the external environment. This behavior is regulated by a complex interaction of peripheral and central mechanisms that control hunger and satiety. The hypothalamus is a brain structure that integrates central and peripheral signals to regulate energy homeostasis and body weight. The hypothalamic nucleus have orexigenic peptides, such as neuropeptide Y and the Agouti-related peptide, and anorexigenic peptides, such as cocaine and amphetamine regulated transcript and proopiomelanocortin. An innovative study of eating behavior in experimental models of neonatal stress separates the mother from the offspring during lactation. This review describes the effects of stress during the neonatal period on general physiological factors, particularly on the control of eating behavior.

    Patients with diabetes mellitus(DM) need psychological support throughout their life span from the time of diagnosis. The psychological make-up of the patients with DM play a central role in self-management behaviors. Without patient’s adherence to the effective therapies, there would be persistent sub-optimal contro of diseases, increase diabetes-related complications,causing deterioration in quality of life, resulting in increased healthcare utilization and burden on healthcare systems. However, provision of psychosocial support is generally inadequate due to its challenging nature of needs and demands on the healthcare systems. This review article examines patient’s psychological aspects in general, elaborates in particular about emotion effects on health, and emotion in relation to other psychological domains such as cognition, self-regulation,self-efficacy and behavior. Some descriptions are also provided on willpower, resilience, illness perception and proactive coping in relating execution of new behaviors,coping with future-oriented thinking and influences of illness perception on health-related behaviors. These psychological aspects are further discussed in relationto DM and interventions for patients with DM. Equipped with the understanding of the pertinent nature of psychology in patients with DM; and knowing the links between the psychological disorders, inflammation and cardiovascular outcomes would hopefully encourages healthcare professionals in giving due attention to the psychological needs of patients with DM.

In the present study, considering the possibility of KT-enhanced toxic effects of other drugs, and KT-induced promotion of an overdose without making the subject aware of the danger due to the attenuation of several painful subjective symptoms, the intraperitoneal (i.p. KT-induced alterations in behaviors and toxic interactions with popular co-abused drugs, the psychostimulants cocaine (COC and methamphetamine (MA, were examined in ICR mice. Results A single dose of KT caused hyperlocomotion in a low (30 mg/kg, i.p. dose group, and hypolocomotion followed by hyperlocomotion in a high (100 mg/kg, i.p. dose group. However, no behavioral alterations derived from enhanced stress-related depression or anxiety were observed in the forced swimming or the elevated plus-maze test. A single non-fatal dose of COC (30 mg/kg, i.p. or MA (4 mg/kg, i.p. caused hyperlocomotion, stress-related depression in swimming behaviors in the forced swimming test, and anxiety-related behavioral changes (preference for closed arms in the elevated plus-maze test. For the COC (30 mg/kg or MA (4 mg/kg groups of mice simultaneously co-treated with KT, the psychostimulant-induced hyperlocomotion was suppressed by the high dose KT, and the psychostimulant-induced behavioral alterations in the above tests were reversed by both low and high doses of KT. For the toxic dose COC (70 mg/kg, i.p.- or MA (15 mg/kg, i.p.-only group, mortality and severe seizures were observed in some animals. In the toxic dose psychostimulant-KT groups, KT attenuated the severity of seizures dose-dependently. Nevertheless, the mortality rate was significantly increased by co-treatment with the high dose KT. Conclusion Our results demonstrated that, in spite of the absence of stress-related depressive and anxiety-related behavioral alterations following a single

  13. Effects of elastic anisotropy on mechanical behavior of intermetallic compounds

    International Nuclear Information System (INIS)

    Fundamental aspects of the deformation and fracture behavior of ordered intermetallic compounds are examined within the framework of linear anisotropic elasticity theory of dislocations and cracks. The orientation dependence and the tension/compression asymmetry of yield stress are explained in terms of the anisotropic coupling effect of non-glide stresses to the glide strain. The anomalous yield behavior is related to the disparity (edge/screw) of dislocation mobility and the critical stress required for the dislocation multiplication mechanism of Frank-Read type. The slip-twin conjugate relationship, extensive faulting, and pseudo-twinning (martensitic transformation) at a crack tip can be enhanced also by the anisotropic coupling effect, which may lead to transformation toughening of shear type

    Benign familial neonatal convulsions (BFNC) is a rare autosomal dominant inherited epilepsy syndrome. Two voltagegated potassium channel genes, KCNQ2 and KCNQ3, have been identified as the genes responsible for BFNC. Here we report two Chinese families with clinical histories of typical BFNC. Using six microsatellite markers, two located at KCNQ2 locus and four at KCNQ3 locus, linkage analysis was performed in the two families, which excluded the linkage of BFNC to KCNQ3, but could not exclude the linkage to KCNQ2. Direct DNA sequencing of the KCNQ2 gene in the two families was performed, and two formerly unknown polymorphisms were identified, but no KCNQ2 mutation was found in the two families. Our study suggests the genetic heterogeneity in Chinese families with BFNC and proves the existence of a new gene locus for BFNC.

    2012-01-01

    Full Text Available Paroxysmal kinesigenic dyskinesia with infantile convulsions (PKD/IC is an episodic movement disorder with autosomal-dominant inheritance and high penetrance, but the causative genetic mutation is unknown. We have now identified four truncating mutations involving the gene PRRT2 in the vast majority (24/25 of well-characterized families with PKD/IC. PRRT2 truncating mutations were also detected in 28 of 78 additional families. PRRT2 encodes a proline-rich transmembrane protein of unknown function that has been reported to interact with the t-SNARE, SNAP25. PRRT2 localizes to axons but not to dendritic processes in primary neuronal culture, and mutants associated with PKD/IC lead to dramatically reduced PRRT2 levels, leading ultimately to neuronal hyperexcitability that manifests in vivo as PKD/IC.

    We report a 23-year-old woman who slowly developed progressive tremulous myoclonus and rare convulsive seizures beginning at the age of 9 and 11 years, respectively. She also showed a mild degree of ataxia and cognitive dysfunction. Convulsive seizures were well suppressed by valproic acid since the age of 17 years, but tremulous myoclonus gradually progressed and became rather intractable in spite of treatment by clonazepam and piracetam. Her cognitive dysfunction was mild (total IQ score in Wechsler Adult Intelligence Scale Revised being 85 points). In addition, she had a fear of walking which disabled her in the daily life although she could actually walk without assistance. The brain MRI showed a mild cerebellar atrophy, and FDG-PET showed a mild hypometabolism in the cerebellar hemispheres. Somatosensory evoked potentials (SEPs) showed enlarged P25 and N33 amplitudes (giant SEPs). A Cystatin B gene analysis exhibited a homozygous expansion of the dodecamer repeat, and thus we made a diagnosis of Unverricht-Lundborg disease (ULD). We also did gene analysis and SEP study to her parents after written informed consents were obtained. They had heterozygous expansion of the dodecamer repeat. The mother also showed enlarged P25 and N33 amplitudes, whereas the father showed normal amplitudes. It is known that degree of clinical symptoms varies among patients with ULD diagnosed by gene analysis. Gene analysis was helpful for a diagnosis of ULD in this patient because the ataxia and cognitive dysfunction were much milder than those commonly seen in patients with ULD. PMID:19227896

    Full Text Available The aim of this study was tome asure effects of domestic violence on children, both child abuse and exposure to marital violence. 300 families were randomly selected in Hermosillo, Sonora, a northwestern Mexican city. Two members of each family were interviewed: the mother anda minor randomly selected among all their children. The research instrument collected demographicinformation, and information regarding mother's and parent's alcohol consumption, marital violence,child abuse, and child misconduct. A structural model was tested which estimated the effects ofchild abuse and exposure to marital violence on child problems. Results showed that the two forms of violence had repercussions on delinquent and antisocial behavior, produced attention problems,depression, anxiety, sadness and the manifestation of somatic symptoms. In addition, mother's education a level had a significant and negative effect on children's behavioral and social problemsand father's educational level inhibited their aggression against their wives. Alcohol consumption was positively related to child abuse. These results seems to indicate that both child abuse andexposure to marital violence rcsult in harmful consequences on children's behavior and well-being.

    Past studies on uses and gratifications theory suggested that consumer motives affect how they will use media and media contents. Recent advertising research has extended the theory to study the use of Internet advertising. The current study explores the effects of consumer motives on their search behavior using Internet advertising. The study employed a 2 by 2 between-subjects factorial experiment design. A total of 120 subjects were assigned to an experiment condition that contains an Internet advertisement varying by advertising appeals (i.e., rational vs. emotional) and product involvement levels (high vs. low). Consumer search behavior (measured by the depth, breadth, total amount of search), demographics, and motives were collected by post-experiment questionnaires. Because all three dependent variables measuring search behavior were conceptually related to each other, MANCOVA procedures were employed to examine the moderating effects of consumer motives on the dependent variables in four product involvement-advertising appeal conditions. Results indicated that main effects for product involvements and advertising appeals were statistically significant. Univariate ANOVA also showed that advertising appeals and product involvement levels influenced the total amount of search. Three-way interactions among advertising appeals, product involvement levels, and information motive were also statistically significant. Implications and future research directions are discussed.

    Full Text Available BACKGROUND: Epilepsy is common in developing countries, and it is often associated with parasitic infections. We investigated the relationship between exposure to parasitic infections, particularly multiple infections and active convulsive epilepsy (ACE, in five sites across sub-Saharan Africa. METHODS AND FINDINGS: A case-control design that matched on age and location was used. Blood samples were collected from 986 prevalent cases and 1,313 age-matched community controls and tested for presence of antibodies to Onchocerca volvulus, Toxocara canis, Toxoplasma gondii, Plasmodium falciparum, Taenia solium and HIV. Exposure (seropositivity to Onchocerca volvulus (OR = 1.98; 95%CI: 1.52-2.58, p<0.001, Toxocara canis (OR = 1.52; 95%CI: 1.23-1.87, p<0.001, Toxoplasma gondii (OR = 1.28; 95%CI: 1.04-1.56, p = 0.018 and higher antibody levels (top tertile to Toxocara canis (OR = 1.70; 95%CI: 1.30-2.24, p<0.001 were associated with an increased prevalence of ACE. Exposure to multiple infections was common (73.8% of cases and 65.5% of controls had been exposed to two or more infections, and for T. gondii and O. volvulus co-infection, their combined effect on the prevalence of ACE, as determined by the relative excess risk due to interaction (RERI, was more than additive (T. gondii and O. volvulus, RERI = 1.19. The prevalence of T. solium antibodies was low (2.8% of cases and 2.2% of controls and was not associated with ACE in the study areas. CONCLUSION: This study investigates how the degree of exposure to parasites and multiple parasitic infections are associated with ACE and may explain conflicting results obtained when only seropositivity is considered. The findings from this study should be further validated.

    Science.gov (United States)

    Pastötter, Bernhard; Bäuml, Karl-Heinz T

    2016-06-01

    The testing effect refers to the finding that retrieval practice of previously studied information enhances its long-term retention more than restudy practice does. Recent work showed that the testing effect can be dramatically reversed when feedback is provided to participants during final recall testing (Storm, Friedman, Murayama, & Bjork, 2014). Following this prior work, in this study, we examined the reversal of the testing effect by investigating oscillatory brain activity during final recall testing. Twenty-six healthy participants learned cue-target word pairs and underwent a practice phase in which half of the items were retrieval practiced and half were restudy practiced. Two days later, two cued recall tests were administered, and immediate feedback was provided to participants in Test 1. Behavioral results replicated the prior work by showing a testing effect in Test 1, but a reversed testing effect in Test 2. Extending the prior work, EEG results revealed a feedback-related effect in alpha/lower-beta and retrieval-related effects in slow and fast theta power, with practice condition modulating the fast theta power effect for items that were not recalled in Test 1. The results indicate that the reversed testing effect can arise without differential strengthening of restudied and retrieval-practiced items via feedback learning. Theoretical implications of the findings, in particular with respect to the distribution-based bifurcation model of testing effects (Kornell, Bjork, & Garcia, 2011), are discussed. PMID:26857480

    2016-02-01

    Ratcheting is known as accumulation of plastic strain during asymmetric cyclic loading of metallic materials under non-zero mean stress. This phenomenon reduces fatigue life of engineering materials and thus limits the life prediction capacity of Coffin-Manson relationship. This study intends to investigate the ratcheting behavior in AISI 4340 steel which is mainly used for designing of railway wheel sets, axles, shafts, aircraft components and other machinery parts. The effect of stress ratio on the ratcheting behaviour in both annealed and normalised conditions were investigated for investigated steel. Ratcheting tests were done at different stress ratios of -0.4, -0.6 and -0.8. The results showed that the material responds to hardening behavior and nature of strain accumulation is dependent on the magnitude of stress ratio. The post ratcheted samples showed increase in tensile strength and hardness which increases with increasing stress ratio and these variations in tensile properties are correlated with the induced cyclic hardening.

  16. Size effect on the static behavior of electrostatically actuated microbeams

    Li Yin; Qin Qian; Lin Wang

    2011-01-01

    We present a new analytical model for electrostatically actuated microbeams to explore the size effect by using the modified couple stress theory and the minimum total potential energy principle. A material length scale parameter is introduced to represent the size-dependent characteristics of microbeams. This model also accounts for the nonlinearities associated with the mid-plane stretching force and the electrostatical force. Numerical analysis for microbeams with clamped-clamped and cantilevered conditions has been performed. It is found that the intensity of size effect is closely associated with the thickness of the microbeam, and smaller beam thickness displays stronger size effect and hence yields smaller deflection and larger pull-in voltage. When the beam thickness is comparable to the material length scale parameter, the size effect is significant and the present theoretical model including the material length scale parameter is adequate for predicting the static behavior of microbeam-based MEMS.

    The recent shortage of 3,4-methylenedioxymethamphetamine (MDMA, Ecstasy) has led to an increased demand for alternative amphetamine-like drugs such as the synthetic cathinone, 4-methylmethcathinone (mephedrone). Despite the re-classification of mephedrone as a Class B restricted substance by the United Kingdom and restrictive legislation by the United States, international policy regarding mephedrone control is still developing and interest in synthetic amphetamine-like drugs could drive the development of future mephedrone analogues. Currently, there is little literature investigating the mechanism of action and long-term effects of mephedrone. As such, we reviewed the current understanding of amphetamines, cathinones, and cocaine emphasizing the potentially translational aspects to mephedrone, as well as contrasting with the work that has been done specifically on mephedrone in order to present the current state of understanding of mephedrone in terms of its risks, mechanisms, and behavioral effects. Emerging research suggests that while there are structural and behavioral similarities of mephedrone with amphetamine-like compounds, it appears that serotonergic signaling may mediate more of mephedrone's effects unlike the more dopaminergic dependent effects observed in traditional amphetamine-like compounds. As new designer drugs are produced, current and continuing research on mephedrone and other synthetic cathinones should help inform policymakers' decisions regarding the regulation of novel 'legal highs.'

  18. Effects of endocannabinoid system modulation on cognitive and emotional behavior

    2011-09-01

    Full Text Available Cannabis has long been known to produce cognitive and emotional effects. Research has shown that cannabinoid drugs produce these effects by driving the brain's endogenous cannabinoid system and that this system plays a modulatory role in many cognitive and emotional processes. This review focuses on the effects of endocannabinoid-system modulation in animal models of cognition (learning and memory and emotion (anxiety and depression. We review studies in which natural or synthetic cannabinoid agonists were administered to directly stimulate cannabinoid receptors or, conversely, where cannabinoid antagonists were administered to inhibit the activity of cannabinoid receptors. In addition, studies are reviewed that involved genetic disruption of cannabinoid receptors or genetic or pharmacological manipulation of the endocannabinoid-degrading enzyme fatty acid amide hydrolase (FAAH. Endocannabinoids affect the function of many neurotransmitter systems, some of which play opposing roles. The diversity of cannabinoid roles and the complexity of task-dependent activation of neuronal circuits may lead to the effects of endocannabinoid system modulation being strongly dependent on environmental conditions. Recent findings are reviewed that raise the possibility that endocannabinoid signaling may change the impact of environmental influences on emotional and cognitive behavior rather than affecting one or another specific behavior.

  20. Neighborhood Disadvantage and Parenting: Behavioral Genetics Evidence of Child Effects.

    Yun, Ilhong; Lee, Julak

    2016-10-01

    The criminological literature has a long tradition of emphasizing the socialization effects that parents have on children. By contrast, evidence from behavioral genetics research gives precedence to child effects on parental management techniques over parental effects on children's outcomes. Considering these diverging lines of scholarship and literature, the current study explores a novel hypothesis that child effects on parenting may be conditioned by the level of the disadvantage of the neighborhood in which the child's family resides. By using measures of perceived parenting as dependent variables, the researchers analyze data on 733 same-sex sibling pairs derived from the Add Health study by taking advantage of the DeFries-Fulker analytical technique. The results show that in adequate neighborhoods, between 43% and 55% of the variance in the measures of perceived parenting is due to genetic factors, whereas shared environmental effects are negligible. In disadvantaged neighborhoods, genetic effects are negligible, whereas shared environmental influences account for between 34% and 57% of the variance in perceived parenting. These results offer partial support for the contextualized gene-environment correlation, which provides initial evidence that although both parental socialization effects and child effects exist, these effects can be modified by the context.

    Full Text Available Brazil has the second largest e-commerce market in the world. One model used in this sector is "collective buying", a feature of which is impulse sales. Consumer behavior can be influenced by several factors, two of which are addressed in this article: the individual impulsivity of consumers and strategies of mix marketing. Impulsive buying is characterized by an unplanned purchase, i.e. the need to acquire the product arises just before the purchase. Consumers respond differently to mixed strategies depending on their degree of impulsivity. Thus, this article aims to analyze the efficacy of different marketing mix strategies for impulsive and non-impulsive consumer purchasing behavior. 137 participants were given a questionnaire containing the Buying Impulsiveness scale from Rook and Fisher (1995, and statements about the marketing strategies used by collective buying sites. Through a regression analysis, three strategies were found to relate more to impulsivity: search for products from well-known brands, search for deals with big discounts and confidence in receiving the product. For e-commerce and researchers, this study elucidates which strategies, from the consumer's perspective, effectively persuade purchasing behavior.

    Allen, Phillip A.; Wilson, Christopher D.

    2003-01-01

    Classical metal plasticity theory assumes that hydrostatic stress has negligible effect on the yield and postyield behavior of metals. Recent reexaminations of classical theory have revealed a significant effect of hydrostatic stress on the yield behavior of various geometries. Fatigue tests and nonlinear finite element analyses (FEA) of Inconel 100 (IN100) equal-arm bend specimens and new monotonic tests and nonlinear finite element analyses of IN100 smooth tension, smooth compression, and double-edge notch tension (DENT) test specimens have revealed the effect of internal hydrostatic tensile stresses on yielding. Nonlinear FEA using the von Mises (yielding is independent of hydrostatic stress) and the Drucker-Prager (yielding is linearly dependent on hydrostatic stress) yield functions were performed. A new FEA constitutive model was developed that incorporates a pressure-dependent yield function with combined multilinear kinematic and multilinear isotropic hardening using the ABAQUS user subroutine (UMAT) utility. In all monotonic tensile test cases, the von Mises constitutive model, overestimated the load for a given displacement or strain. Considering the failure displacements or strains for the DENT specimen, the Drucker-Prager FEM s predicted loads that were approximately 3% lower than the von Mises values. For the failure loads, the Drucker Prager FEM s predicted strains that were up to 35% greater than the von Mises values. Both the Drucker-Prager model and the von Mises model performed equally-well in simulating the equal-arm bend fatigue test.

    1988-01-01

    The present study assessed transfer of visual training effects for myopia using two different training stimuli and a single subject A-B-C-A design. A male student volunteer, with lens prescription of -3.0 D (left) and -2.0 D (right), served as the subject. During baseline (10 sessions), visual acuity was assessed by two behavioral acuity tests. One test consisted of 50 line drawings of common objects as testing stimuli and the other test had 50 Chinese characters. A procedure including stimulus fading and reinforcement (positive verbal feedback) was used to train the subject to identify either pictorial stimuli or Chinese characters presented from a distance. Training was effective in improving performance on both behavioral acuity tests during the training phases and follow-up but the change was more pronounced on the specific stimuli being used for training. Refractive errors assessed on a weekly basis showed no change in the physiology of both eyes. These results suggest that effects of visual training only partially transferred to untrained stimuli.

    2014-01-01

    The effect of moisture content upon compressive mechanical behavior of concrete under impact loading was studied. The axial rapid compressive loading tests of over 50 specimens with five different saturations were executed. The technique “split Hopkinson pressure bar” (SHPB) was used. The impact velocity was 10 m/s with corresponding strain rate of 50 s−1. The compressive behavior of materials was measured in terms of stress−strain curves, dynamic compressive strength, dynamic increase factor (DIF) and critical strain at a maximum stress. The data obtained from test indicate that both ascending and descending portions of stress−stain curves are affected by moisture content. However, the effect is noted to be more significant in ascending portion of the stress−strain curves. Dynamic compressive strength is higher at lower moisture content and weaker at higher moisture content. Furthermore, under nearly saturated condition, an increase in compressive strength can be found. The effect of moisture content on the average DIF of concrete is not significant. The critical compressive strain of concrete does not change with moisture content.

    1997-02-01

    Full Text Available Crotoxin has been detoxified with gamma radiation in order to improve crotalic antiserum production. Nevertheless, present knowledge of the biological characteristics of irradiated crotoxin is insufficient to propose it as an immunizing agent. Crotoxin is known to increase the emotional state of rats and to decrease their exploratory behavior (Moreira EG, Nascimento N, Rosa GJM, Rogero JR and Vassilieff VS (1996 Brazilian Journal of Medical and Biological Research, 29: 629-632. Therefore, we decided 1 to evaluate the effects of crotoxin in the social interaction test, which has been widely used for the evaluation of anxiogenic drugs, and 2 to determine if irradiated crotoxin induces behavioral alterations similar to those of crotoxin in the social interaction, open-field and hole-board tests. Male Wistar rats (180-220 g were used. Crotoxin (100, 250, and 500 µg/kg was injected intraperitoneally 2 h before the social interaction test. Similarly, irradiated crotoxin (2000 Gy gamma radiation from a 60Co source was administered at the doses of 100, 250, and 500 µg/kg for the hole-board test, and at the doses of 1000 and 2500 µg/kg for the open-field and social interaction tests. ANOVA complemented with the Dunnett test was used for statistical analysis (P<0.05. Crotoxin decreased the social interaction time (s at the doses of 100, 250 and 500 µg/kg (means ± SEM from 51.6 ± 4.4 to 32.6 ± 3.7, 28.0 ± 3.6 and 31.6 ± 4.4, respectively. Irradiated crotoxin did not induce behavioral alterations. These results indicate that 1 crotoxin may be an anxiogenic compound, and 2 in contrast to crotoxin, irradiated crotoxin was unable to induce behavioral alterations, which makes it a promising compound for the production of crotalic antiserum

    Testosterone is typically understood to contribute to maleness and masculinity, although it also responds to behaviors such as competition. Competition is crucial to evolution and may increase testosterone but also is selectively discouraged for women and encouraged for men via gender norms. We conducted an experiment to test how gender norms might modulate testosterone as mediated by two possible gender→testosterone pathways. Using a novel experimental design, participants (trained actors) performed a specific type of competition (wielding power) in stereotypically masculine vs. feminine ways. We hypothesized in H1 (stereotyped behavior) that wielding power increases testosterone regardless of how it is performed, vs. H2 (stereotyped performance), that wielding power performed in masculine but not feminine ways increases testosterone. We found that wielding power increased testosterone in women compared with a control, regardless of whether it was performed in gender-stereotyped masculine or feminine ways. Results supported H1 over H2: stereotyped behavior but not performance modulated testosterone. These results also supported theory that competition modulates testosterone over masculinity. Our findings thus support a gender→testosterone pathway mediated by competitive behavior. Accordingly, cultural pushes for men to wield power and women to avoid doing so may partially explain, in addition to heritable factors, why testosterone levels tend to be higher in men than in women: A lifetime of gender socialization could contribute to "sex differences" in testosterone. Our experiment opens up new questions of gender→testosterone pathways, highlighting the potential of examining nature/nurture interactions and effects of socialization on human biology.

  15. Physiological and behavioral effects of coniferyl benzoate on avian reproduction.

    1993-10-01

    Various plant secondary metabolites related to cinnamic acid are of interest because of their repellency to birds and their occurrence in ecologically important food items. Coniferyl benzoate (CB), a phenylpropanoid ester that occurs in quaking aspen (Populus tremuloides) is of particular ecological interest because of its effect on ruffed grouse (Bonasa umbellus) feeding behavior and its possible influence on the population dynamics of this bird. During detoxification processes, CB and other analogous compounds are metabolized into by-products, such as ferulic acid (FA), that can cause anti-reproductive effects. We tested whether consumption of CB produces antire-productive effects similar to FA using male and female Japanese quail (Coturnix coturnix) as avian models for ruffed grouse. The parameters we investigated included: the production, morphology, and development of eggs; reproductive characteristics influenced by estrogen; serum prolactin levels; and male reproductive behavior. Dietary CB did not produce antireproductive effects similar to FA at intake levels that Japanese quail and ruffed grouse would freely consume. Consumption of CB by Japanese quail significantly reduced egg production and body mass but did not affect male reproductive performance. Coniferyl benzoate's effect on egg production may be explained by lower energy acquisition and retention rather than endocrine changes per se. Contrary to previous reports, it is unlikely that FA, or similar compounds act directly as estrogen mimics or antagonists. Although, CB did reduce egg production in quail, it is unlikely that it would affect egg production in wild ruffed grouse. Detoxification costs and the effects of CB on nutrient utilization may explain why ruffed grouse avoid high dietary levels of CB. PMID:24248582

  17. Effects of prenatal ionizing irradiation on neural function and behavior

    International Nuclear Information System (INIS)

    Behavioral studies in the past decade on postnatal effects of prenatal ionizing irradiation (125-R) revealed alterations in circadian locomotor activity and modifications of duration, frequency and sequences of certain behavioral acts in irradiated rats. Other studies have shown that the effect of irradiation (150-R) and enriched environment were both significant in initial, repetitive and total error scores while at 200-R enrichment was less effective. Rats irradiated on the 13th, 14th and 15th day of gestation were born with a hopping gait, paired hind and forelimbs moving in unison. Thoracic cord section led to crossed extention hind-limb reflexes in control rats and simultaneus withdrawal of hind limbs in hopping rats, in response to pinprick. In 90 day old squirrel monkeys the percent of correct response in visual orientation, discrimination and reversal learning in 50- and 100-R offspring (Co 60 irradiation at 89-90 days gestation) were significantly lower than those of controls, and differences in reversal learning persisted undiminished at 2 years of age. Time required for body righting, head-up orientation and climbing at 450 incline was significantly greater in irradiated (mainly 100-R) than control animals at from 2 to 28 days of age. Visual acuity levels of 50- and 100-R 30 day old infants were significantly lower than in control infants. Stabilimeter activity in the dark was significantly higher in 50- and 100-R 30 day old infants than in controls. In the squirrel monkey studies effects of Co 60 irradiation (100-R) on postnatal development of the brain and behaviour can be identified at statistically significant levels of confidence independent of offspring nursery rearing effects.

  1. Hemi-convulsion-hemiplegia syndrome revisited: longitudinal MRI findings in 10 children

    International Nuclear Information System (INIS)

    Hemi-convulsion-hemiplegia syndrome (HHS) is a rare severe epilepsy of infancy consisting of unilateral convulsive status epilepticus immediately followed by transient or lasting ipsilateral hemiplegia. HHS may occur either in patients with previous brain pathology or without any identified cause, so-called 'idiopathic HHS'. We retrospectively analysed clinical and MRI longitudinal findings of a series of 10 patients (six females, four males) presenting with HHS. Age at the study inclusion ranged from 2 years 6 months to 15 years (mean of 5 y 10 mo, median 4 y 2 mo). After defining magnetic resonance imaging (MRI) features as 'typical', i.e. strictly unilateral involvement, and 'atypical', i.e. bilateral, we compared clinical data from both groups. Cognitive level was assessed using Brunet-Lezine or Wechsler scales. HHS occurred at a mean age of 20.5 months (range 8-48 mo). In all cases, status epilepticus lasted for more than 1 hour and was characterised by unilateral clonic seizures followed by ipsilateral hemiplegia (persistent in five patients). Two patients in this series died: the first from multi-organ failure 2 weeks after the status epilepticus and the other from a second episode of ipsilateral intractable febrile status epilepticus 3 years after the first episode. Early MRI (days 1-7 from status epilepticus) showed hemispheric cytotoxic oedema in all, extending to the contralateral side for one. T2 hyperintensity in the basal ganglia was disclosed in 70% of patients and in the hippocampus in 60%. After 1 month (in intermediate and chronic phases), all surviving patients but one showed hemispheric cortical atrophy corresponding to the regions involved during the early stage. Comparing clinical features of patients presenting with 'typical' features, to those with 'atypical' findings, the second group presented psychomotor delay before status epilepticus. This series underlines the major value of early MRI

    Use of conditioned taste aversion (CTA) has been proposed to reduce consumption of California condor (Gymnogyps californianus) eggs by ravens (Corvus corax). Although landrin has induced aversions in ravens and other birds, no data were available on behavioral and physiological effects of landrin on condors, non-target birds that might consume treated eggs. Because condors are endangered, we selected taxonomically related surrogates to approximate the effects on condors of acute oral doses of landrin. Seven black vultures (Coragyps atratus), 2 turkey vultures (Cathartes aura), and 2 king vultures (Sarcoramphus papa) received landrin and placebo treatments 1 week apart. Plasma cholinesterase (ChE) activity was monitored at zero, 3, and 24 hours posttreatment, and behavioral observations were made for 2 hours posttreatment. The doses tested were nonlethal, and ChE levels approached normal within 24 hours after treatment. Only the frequency of vomiting differed statistically between the placebo and landrin treatment. We conclude that with appropriate precautions, landrin can be used in applications of CTA to discourage consumption of condor eggs by ravens, while posing no apparent risk to reintroduced condors.

  3. Effect of fault jogs on frictional behavior: An experimental study

    Institute of Scientific and Technical Information of China (English)

    2008-01-01

    Studying the effect of geometrically irregular bodies on the mechanical behavior of fault activity is of significance in understanding the seismic activity along a fault zone. By using rock mechanics ex- periment with medium-scale samples, we have studied the effect of fault jogs, the most common irregularity along fault zones, on frictional behavior. The research indicates that extensional fault jog can be easily fractured because of its low strength and the fractured jog has no obvious resistance to fault sliding, and the micro-fractures occurring in the jog are indicative of stick-slip along the faults. The fault zone containing extensional jogs is characterized by velocity weakening and can be described by rate and state friction law. Compressional fault jog makes fault sliding more difficult because of its high fracturing strength, but the micro-fractures occurring in the tensile areas around fault ends at higher stress level can provide necessary condition for occurrence of stick-slip along the faults before the jog is fractured and thus act as precursors of fault instability. Compression jog can be taken as a stable indicator of fault segmentation until the jog is completely fractured and two faults are linked.

    Full Text Available The purpose of this study is to determine the level of display of effective leadership behaviors by school principals. Descriptive design was used in this research. The target population of the study is the teachers who work in primary and high schools in Kartal, Maltepe and Üsküdar located in İstanbul, The sample consists of 703 primary and high school teachers randomly selected from the population. The study was carried out quantitatively and data were gathered through the 30-item 5-point Likert-type scale developed by the researchers. Data were analyzed by percentages, frequencies, means and crosstabs. In order to find out sources of differences and do pair comparisons, Mann-Whitney U tests were employed while Kruskal-Wallis H tests were used to do comparisons of variables having more than three levels. According to the results obtained from this research, teachers stated that principals “sometimes” demonstrate effective leadership behaviors. When mean scores of all the items were checked, the highest score was earned by the item, “The principal plans the future of the school” and the lowest score by “Principals are open to be criticized.” There were significant differences based on gender and teaching experience of teachers and school types.

    1993-01-01

    The effects of mazindol, cocaine and D-amphetamine were studied in rhesus monkeys trained to self-administer cocaine, and in rats and squirrel monkeys trained to discriminate cocaine from saline. Non-contingent intravenous drug injections were administered to monkeys responding under a session consisting of a 5-min period during which lever-pressing produced food reinforcement and a 60-min session in which responding produced i.v. cocaine infusions (10 or 33 micrograms/kg per infusion). Acute i.v. injections of cocaine (0.1-1.7 mg/kg), D-amphetamine (0.1-1 mg/kg) and the dopamine re-uptake inhibitor mazindol (0.03-0.56 mg/kg) given 5 min before the session decreased self-administration of cocaine, but also decreased rates of behavior maintained by the presentation of food. In both rats and squirrel monkeys trained to discriminate cocaine from saline in a two-lever, food-maintained procedure, mazindol, cocaine and D-amphetamine substituted for cocaine in a dose-related manner. Despite a lack of selectivity to decrease cocaine self-administration as compared to behavior maintained by food, the present data provide some rationale for further consideration of mazindol as a potential pharmacotherapy for stimulant abuse, due to its relatively low abuse liability and cocaine-like discriminative stimulus effects.

    From October 1996 to March 1997, 31 children with febrile convulsions were admitted to the University Hospital, Kuala Lumpur. Human Herpesvirus 6 (HHV 6) was virologically and/or serologically confirmed to be the cause of the febrile episode in 5 of these children (16.1%). Age, sex and other associated clinical features (diarrhoea, cough, running nose and type of seizure) were not useful in differentiating cases of febrile convulsion due to HHV 6 from those of other aetiology. However, uvulo-palatoglossal junctional ulcers were noted in children in whom the cause of the seizure could be attributed to HHV 6 but not in the remaining cases in the study group. HHV 6 DNA was detected in peripheral blood mononuclear cells from all patients with febrile convulsions attributed to HHV6, and in patients shown serologically to have already been exposed to the virus by nested polymerase chain reaction amplification. Only genotype HHV 6B was detected from patients with seizure due to HHV 6 but both genotype 6A and 6B were detected in the remaining cases studied. PMID:10968110

    To determine the knowledge, attitude and practice (KAP) of home management of febrile convulsion (FC), by mothers in the community, focus group discussions (FGD) were conducted in two communities, Uselu (urban) and Evbuomodu village (rural), both in Edo State, Southern Nigeria. The study was conducted between December 2000 and February 2001. Our findings show that 71% of urban mothers compared to 25% of rural mothers attributed the cause of FC to fever (chi(2)=24.17: p<0.001). Seventy-five percent of mothers from rural community and 28.6% of urban mothers attributed the cause to witchcraft and/or evil spirits. Twenty-five percent of rural mothers also attributed abnormality of the spleen as a cause of FC. All the mothers, both urban and rural, were not directly involved in the management of the convulsive episode due to panic and confusion. Ninety-two percent of urban and all the rural mothers permitted the use of traditional medicine while 7.1% of urban mothers employed prayers during convulsion. Twenty percent of urban and twenty-two percent of rural mothers use urine (human and or cow's) for treating FC at home. Other home remedies include kerosene, fuel and crude oil. Mass enlightenment campaign for the community, especially the rural, against use of harmful traditional remedies to treat FC at home is strongly advised. PMID:12127675

    The identification and the modeling of epilepsy convulsions during everyday life using wearable devices would enhance patient anamnesis and monitoring. The psychology of the epilepsy patient penalizes the use of user-driven modeling, which means that the probability of identifying convulsions is driven through generalized models. Focusing on clonic convulsions, this pre-clinical study proposes a method for generating a type of model that can evaluate the generalization capabilities. A realistic experimentation with healthy participants is performed, each with a single 3D accelerometer placed on the most affected wrist. Unlike similar studies reported in the literature, this proposal makes use of [Formula: see text] cross-validation scheme, in order to evaluate the generalization capabilities of the models. Event-based error measurements are proposed instead of classification-error measurements, to evaluate the generalization capabilities of the model, and Fuzzy Systems are proposed as the generalization modeling technique. Using this method, the experimentation compares the most common solutions in the literature, such as Support Vector Machines, [Formula: see text]-Nearest Neighbors, Decision Trees and Fuzzy Systems. The event-based error measurement system records the results, penalizing those models that raise false alarms. The results showed the good generalization capabilities of Fuzzy Systems. PMID:27354194

    We analyzed with EEG-video monitoring the epileptic activity recorded during the latent and chronic periods in rats undergoing 30 or 120 min pilocarpine-induced convulsive status epilepticus (SE). Interictal discharges frequency in the entorhinal cortex (EC) of animals exposed to 120 min SE was significantly higher in the chronic than in the latent period. Following seizure appearance, interictal spikes diminished in duration in the CA3 of the 120 min SE group, and occurred at higher rates in the amygdala in all animals. Rats exposed to 120 min SE generated shorter seizures but presented twice as many non-convulsive seizures per day as the 30 min group. Finally, seizures most frequently initiated in CA3 in the 120 min SE group but had similar onset in CA3 and EC in the 30 min group. These findings indicate that convulsive SE duration influences the development of interictal and ictal activity, and that interictal discharges undergo structure-specific changes after seizure appearance.

  11. Ionizing radiation: effects upon acquisition and performance of behavior

    International Nuclear Information System (INIS)

    The present study, using rats as subjects, attempted to assess the effects of multiple exposures to gamma radiation upon behavior in two procedures of a multiple schedule of repeated acquisition and performance. With an experimental chamber containing three levers displaced horizontally, left (l), center (c) and right (r), different levels of complexity were programmed for procedures A and B. In both procedures a new sequence of three responses was programmed for each session (lcr, lrc, clr, crl, rlc) for the acquisition component, whereas for the performance component the same sequence was maintained throughout the sessions. The completion of three sequences (nine responses) was followed by reinforcement and incorrect responses were followed by time-out without correction procedures. In procedure A the sequences consisted of one response in each lever (for example, crl→crl→crl→reinforcement) while in procedure B a sequence consisted of three response in the same lever, with the following three responses having to occur in a different lever (for example, ccc→rrr→lll→reinforcement). Six subjects were trained in each procedure. Base line data showed, by means of error percentage, that procedure B regardless of being more complex represented a lower difficulty level than procedure A: subjects in procedure B displayed, in general, a lower number of errors per session. After training in these procedures of repeated acquisition and performance, the subjects were exposed to doses of ionizing radiation of 3.0, 4.5, 6.0 and 8.0 Gy, with an interval of 45 days between exposures. With measurements of response rate and obtained reinforcers, the data showed a dose-response relation, with higher doses producing lower rates of responses and reinforcers. Percentage of errors was higher after doses of 6.0 and 8.0 Gy in the performance component, while changes in error patterns occurred in the acquisition component. The effects of radiation was more evident and orderly

    We investigate structural coupling of the MnO6 octahedra across a film/substrate interface and the resultant changes of the physical properties of ultrathin La2/3Sr1/3MnO3 (LSMO) films. In order to isolate the effect of interfacial MnO6 octahedral behavior from that of epitaxial strain, LSMO films are grown on substrates with different symmetry and similar lattice parameters. Ultrathin LSMO films show an increased magnetization and electrical conductivity on cubic (LaAlO3)0.3(Sr2AlTaO6)0.7 (LSAT) compared to those grown on orthorhombic NdGaO3 (NGO) substrates, an effect that subsides as the thickness of the films is increased. This study demonstrates that interfacial structural coupling can play a critical role in the functional properties of oxide heterostructures. PMID:24697503

  17. Effect of powder characteristics on sintering behavior of silicon nitride

    International Nuclear Information System (INIS)

    Sintering behavior of high-quality Si3N4 produced by imide decomposition method was studied to verify the effect of powder characteristics on densification and mechanical properties of Si3N4 ceramics. Oxygen content and its distribution in the particle had much influence on the sintering activity of Si3N4 powder. Although densification of Si3N4 doped with Y2O3 and Al2O3 was promoted by oxygen contaminant, especially surface oxygen of the starting powder, bending strength of pressureless-sintered Si3N4 showed maximum value at 1.5 wt% of oxygen content and was deteriorated with increasing oxygen content over 1.5 wt%. This deterioration in strength was caused by the decrease in fracture toughness of grain boundary phase. Carbon more than 0.1 wt% exhibited detrimental effects on both densification and bending strength. (orig.)

  18. Effects of Website Interactivity on Online Retail Shopping Behavior

    Science.gov (United States)

    Islam, Hafizul

    Motivations to engage in retail online shopping can include both utilitarian and hedonic shopping dimensions. To cater to these consumers, online retailers can create a cognitively and esthetically rich shopping environment, through sophisticated levels of interactive web utilities and features, offering not only utilitarian benefits and attributes but also providing hedonic benefits of enjoyment. Since the effect of interactive websites has proven to stimulate online consumer’s perceptions, this study presumes that websites with multimedia rich interactive utilities and features can influence online consumers’ shopping motivations and entice them to modify or even transform their original shopping predispositions by providing them with attractive and enhanced interactive features and controls, thus generating a positive attitude towards products and services offered by the retailer. This study seeks to explore the effects of Web interactivity on online consumer behavior through an attitudinal model of technology acceptance.

    Effect of organic solvents content on crystallization behavior of xylitol was studied. Solubility and crystallization kinetics of xylitol in methanol-water system were experimentally determined. It was found that the solubility of xylitol at various methanol content all increases with increase of temperature. But it decreases when increasing methanol content at constant temperature. Based on the theory of population balance, the nucleation and growth rates of xylitol in methanol-water mixed solvents were calculated by moments method. From a series of experimental population density data of xylitol gotten from a batch-operated crystallizer, parameters of crystal nucleation and growth rate equations at different methanol content were got by the method of nonlinear least-squares. By analyzing, it was found that the content of methanol had an apparent effect on nucleation and growth rate of xylitol. At constant temperature, the nucleation and growth rate of xylitol all decrease with increase of methanol content.

    Full Text Available This study develops and tests an integrative model to examine the relationships among customer value, satisfaction and behavioral intentions based upon a typology of consumer search behaviors. The model was tested using surveyed data from 546 customers of car insurance in Melbourne, Australia. The findings demonstrate that each type of consumer (passive, rational-active, relational-dependent, performs differently on the relationships among customer value, satisfaction, and behavioral intentions. The identification of value, satisfaction, and behavioral intentions within each search behavior allows managers to deliver optimal value and satisfaction to their consumers.

    Full Text Available The author investigates how consumer search behavior typology affects the relationship between customer satisfaction and behavioral intentions. The results show that the type of consumer as defined by whether and how they search for information (passive, rational-active, relational-dependent perceive different levels of satisfaction and performs differently on satisfaction behavioral intentions linkages. Relational-dependent and rational active consumers are found to perceive higher satisfaction levels, and to express stronger intentions to engage in positive behavioral intentions than passive consumers. The identification of satisfaction and behavioral intentions within each search type allows managers to satisfy their consumers; hence, the company will obtain higher profit.

    Pregnant Sprague-Dawley rats treated with 0, 2.0 or 6.0 mg/kg of methylmercury on days 6-9 of gestation or left untreated as part of the Collaborative Behavioral Teratology Study (CBTS) were assigned to either the CBTS or Cincinnati Test protocol after birth. Offspring assigned to the Cincinnati test system were evaluated for growth, mortality, incisor eruption, eye opening, vaginal patency, surface righting, negative geotaxis, pivoting, olfactory orientation, swimming ontogeny, figure-8 activity, and complex water maze (Biel) problem solving. Methylmercury lengthened gestation, reduced maternal weight, and increased offspring preweaning mortality at the higher dose. This dose also accelerated upper and lower incisor eruption and delayed vaginal patency development. The high dose produced a non-significant reduction in offspring weight from shortly after birth to 30 days of age, and a significant reduction in weight by 60 days of age. This dose caused a significant delay in surface righting development and swimming ontogeny, while the low dose accelerated negative geotaxis turning and swimming angle development. The high dose reduced postweaning figure-8 activity, increased Biel water maze time, errors, and proportion of trial failures (no escape within 6 min), although the effect on errors was not significant. It was concluded that at the doses and exposure period used here, methylmercury was confirmed to be a potent behavioral teratogen using the Cincinnati test system. This finding is in agreement with the results obtained with the same treatment regimen in the CBTS. Two tests from the Cincinnati test system, swimming ontogeny and Biel maze, provided evidence that they would significantly improve the detection power of the CBTS test battery. PMID:3835472

    The aim of this study is to determine the efficacy of prophylactic treatment for patients with febrile convulsions (FCs) in whom electroencephalograms (EEGs) revealed epileptiform discharges. We retrospectively investigated 43 patients who met the following criteria: (a) at least one FC during the study period; (b) epileptiform discharges were first recognized; (c) no unevoked seizures before epileptiform discharges were first seen; (d) normal psychomotor development and no neurological abnormality; and (e) follow-up >3 years. The clinical characteristics, treatment, and a later occurrence of FCs or unevoked seizures were studied. EEGs revealed focal epileptiform discharges in 25 patients and generalized ones in 18. There was no significant difference in the rate of recurrence of FC or occurrence of unevoked seizures between those with focal and generalized epileptiform discharges. No prophylaxis was performed in ten patients, 14 patients being treated with intermittent diazepam and 19 with a daily anticonvulsant. The rate of recurrence of FC was not significantly different between patients with and without prophylaxis. Unevoked seizures were only observed in two patients undergoing daily treatment. Intermittent or daily anticonvulsant therapy will not reduce the risk of recurrence of FCs or later development of unevoked seizures in patients with FC with epileptiform discharges. PMID:15130690

    OBJECTIVES: To identify clinical features and therapeutic decisions that influence admission to the Intensive Care unit (ICU) in children presenting with convulsive status epilepticus (CSE). METHODS: We evaluated 47 admissions with status epilepticus to a tertiary paediatric hospital A&E over a three year period (2003-2006). Following initial management 23 episodes required admission to ICU and 24 were managed on a paediatric ward. We compared clinical, demographic data and compliance with our CSE protocol between the ICU and ward groups. RESULTS: Median age at presentation in the ICU group was 17 months (range 3 months-11 years) compared to 46 months in the ward group (range 3 months-10 years). Fifty per cent of patients in both groups had a previous history of seizures. Median duration of pre-hospital seizure activity was 30 min in both groups. More than two doses of benzodiazepines were given as first line medication in 62% of the ICU group and 33% of the ward group. Among children admitted to ICU with CSE, 26% had been managed according to the CSE protocol, compared to 66% of children who were admitted to a hospital ward. Febrile seizures were the most common aetiology in both groups. CONCLUSION: Younger age at presentation, administration of more than two doses of benzodiazepines and deviation from the CSE protocol appear to be factors which influence admission of children to ICU. Recognition of pre-hospital administration of benzodiazepines and adherence to therapeutic guidelines may reduce the need for ventilatory support in this group.

    Full Text Available The clinical data of 182 children with convulsive status epilepticus (CSE were analyzed. There were 21 cases with refractory status epilepticus (RSE and 161 cases with non-refractory status epilepticus (non-RSE. Etiological factors mainly included epilepsy in 54 cases, intracranial infection in 49 cases, and complex febrile seizure in 44 cases. In the ictal stage, 102 cases were treated with clonazepam by intravenous injection, 54 cases with diazepam by intravenous injection, 46 cases with midazolam by intravenous injection, 36 cases with phenobarbital by muscular injection, and 32 cases with 6.5% chloral hydrate by nosal feeding or clyster. The etiology of CSE in children is various. Epilepsy, intracranial infection and complex febrile seizure are the main causes. Poor prognosis and high mortality often occur in RSE caused by severe viral encephalitis. So the fundamental principle of treatment is to control CSE quickly and avoid the damage of brain and other important organs. DOI: 10.3969/j.issn.1672-6731.2015.11.009

  8. Synthetic trehalose dicorynomycolate (S-TDCM). Behavioral effects and radioprotection

    International Nuclear Information System (INIS)

    This study evaluated synthetic trehalose dicorynomycolate (S-TDCM), an immunomodulator, for its survival enhancing capacity and behavioral toxicity in B6D2F1 female mice. In survival experiments, mice were administered S-TDCM (25-400 μg/mouse i.p.) 20-24 hr before 5.6 Gy mixed-field fission-neutron irradiation (n) and γ-photon irradiation. The 30-day survival rates for mice treated with 100-400 μg/mouse S-TDCM were significantly enhanced compared to controls. Toxicity of S-TDCM was measured in nonirradiated mice by locomotor activity, food intake, water consumption, and alterations in body weight. A dose-dependent decrease was noted in all behavioral measures in mice treated with S-TDCM. Doses of 100 and 200 μg/mouse S-TDCM significantly reduced motor activity beginning 12 hr postinjection with recovery by 24 hr. A dose of 400 μg/mouse significantly decreased activity within the first 4 hr after administration and returned to control levels by 32 hr following injection. Food and water intake were significantly depressed at doses of 200 and 400 μg/mouse on the day following drug administration, and were recovered in 24 hr. Body weight was significantly decreased in the 200 μg/mouse group for 2 days and in the 400 μg/mouse group for 4 days following injection. A dose of 100 μg/mouse effectively enhanced survival after fission-neutron irradiation with no adverse effect on food consumption, water intake, or body weight and a minimal, short-term effect on locomotor activity.

  9. Molecular Mechanism: ERK Signaling, Drug Addiction, and Behavioral Effects.

    Sun, Wei-Lun; Quizon, Pamela M; Zhu, Jun

    2016-01-01

    Addiction to psychostimulants has been considered as a chronic psychiatric disorder characterized by craving and compulsive drug seeking and use. Over the past two decades, accumulating evidence has demonstrated that repeated drug exposure causes long-lasting neurochemical and cellular changes that result in enduring neuroadaptation in brain circuitry and underlie compulsive drug consumption and relapse. Through intercellular signaling cascades, drugs of abuse induce remodeling in the rewarding circuitry that contributes to the neuroplasticity of learning and memory associated with addiction. Here, we review the role of the extracellular signal-regulated kinase (ERK), a member of the mitogen-activated protein kinase, and its related intracellular signaling pathways in drug-induced neuroadaptive changes that are associated with drug-mediated psychomotor activity, rewarding properties and relapse of drug seeking behaviors. We also discuss the neurobiological and behavioral effects of pharmacological and genetic interferences with ERK-associated molecular cascades in response to abused substances. Understanding the dynamic modulation of ERK signaling in response to drugs may provide novel molecular targets for therapeutic strategies to drug addiction. PMID:26809997

    This research tests whether the perception of red in an achievement context evokes avoidance behavior without conscious awareness and also examines the context specificity of the hypothesized red effect. In Experiment 1, participants were briefly shown red or green on the cover of an analogies test that they would ostensibly take (an achievement context) or rate on likability of (a nonachievement context) in an adjacent lab. Those shown red, relative to those shown green, knocked fewer times on the door of the adjacent lab in the achievement context; no red-green difference in knocking was observed in the nonachievement context. In Experiment 2, participants were briefly shown red, green, or gray on the cover of an IQ test that they would ostensibly take. Those shown red moved their body away from the test cover to a greater degree than did those shown green or gray. This research contributes to incipient work on color psychology and to the more established literature on the automatic link between evaluation and behavior. PMID:19223458

    2008-12-01

    Full Text Available Abstract Background It is not known if there is a relationship between input rate and incidence of bupropion-induced seizures. This is important, since different controlled release formulations of bupropion release the active drug at different rates. Methods We investigated the effect of varying the intraperitoneal infusion rates of bupropion HCl 120 mg/kg, a known convulsive dose50 (CD50, on the incidence and severity of bupropion-induced convulsions in the Swiss albino mice. A total of 69 mice, approximately 7 weeks of age, and weighing 21.0 to 29.1 g were randomly assigned to bupropion HCl 120 mg/kg treatment by intraperitoneal (IP administration in 7 groups (9 to 10 animals per group. Bupropion HCl was infused through a surgically implanted IP dosing catheter with infusions in each group of 0 min, 15 min, 30 min, 60 min, 90 min, 120 min, and 240 min. The number, time of onset, duration and the intensity of the convulsions or absence of convulsions were recorded. Results The results showed that IP administration of bupropion HCl 120 mg/kg by bolus injection induced convulsions in 6 out of 10 mice (60% of convulsing mice in group 1. Logistic regression analysis revealed that infusion time was significant (p = 0.0004; odds ratio = 0.974 and increasing the IP infusion time of bupropion HCl 120 mg/kg was associated with a 91% reduced odds of convulsions at infusion times of 15 to 90 min compared to bolus injection. Further increase in infusion time resulted in further reduction in the odds of convulsions to 99.8% reduction at 240 min. Conclusion In conclusion, the demonstration of an inverse relationship between infusion time of a fixed and convulsive dose of bupropion and the risk of convulsions in a prospective study is novel.

    The effects of torrefaction on hemicellulose characteristics and its pyrolysis behaviors were studied in detail. The oxygen content decreased significantly after torrefaction, leading to the increase of high heating value. Two-dimensional perturbation correlation analysis based on diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) was performed to characterize the structural evolutions. It was found the dehydration of hydroxyls and the dissociation of branches were the main reactions at low torrefaction temperature. When the temperature further increased, the depolymerization of hemicellulose and the fragmentation of monosaccharide residues occurred. The distributed activation energy model with double Gaussian functions based on reaction-order model was used to investigate the pyrolysis kinetics. The results showed that torrefaction enhanced the activation energy for degradation reactions while lowered that for condensation reactions, and increased the devolatilization contribution of condensation reactions. Besides, torrefaction decreased the yields of typical pyrolytic products, such as acids, furans, alicyclic ketones and so on. PMID:27469091

    Study was made on the effect of surface modification on the behaviors of cerium oxide nanopowders. A surfactant-sodium dodecyl sulfate(C12H25SO4Na) was used to modify the surface of CeO2 powder particles. The unmodified and modified CeO2 powders were characterized by using a powder comprehensive characteristic tester, laser particle size analyzer, specific surface area tester, X-ray diffraction tester, and a scanning electron microscope. The testing and analysis results showed that C12H25SO4Na surface modification might increase the flowability and dispersity, and decrease the specific surface area and agglomeration of CeO2 powders. The mechanism of the surface modification of CeO2 powder particles was also discussed.

    Full Text Available The study has monitored the effects of transport stress on some biochemical indicators of stress and behavior lambs at time of slaughter. The research was carried out in the cold season, on a number of 120 lambs, transported for 6h- 16h, to be slaughtered. During our research, we followed the changes in bodyweight, behaviours expressed by sheep, and plasma cortisol levels. Bodyweight loss recorded in the slaughterhouse to 24 hours of departure transportation was of 4-5%. The behavioural manifestations of lambs were different from the destination, depending on journey duration. Lambs behaviour was different depending on the journey, the resting and watering were mostly present manifestations. Increased in cortisol levels measured at 3 h after leaving the vehicle was maintained at 9 h after the journey. Increased duration of rest before slaughter can reduce the stress of transport in case of lambs ensures obtaining good quality meat.

    Caffeine consumption has been increasing rapidly in adolescents; however, most research on the behavioral effects of caffeine has been conducted in adults. Two experiments were conducted in which adolescent male and female rats were treated with a moderate dose of caffeine (0.25g/l) in their drinking water beginning on P26-28. In the first experiment, animals were maintained on caffeinated drinking water or normal tap water for 14days and were then tested for behavioral and striatal c-Fos response to amphetamine (1.5mg/kg). In the second experiment, rats were maintained on caffeinated drinking water or normal tap water beginning on P28 and were tested for novel object recognition, anxiety in the light/dark test (L/D) and elevated plus maze (EPM), and depressive like behavior in the forced swim test (FST) beginning on the 14th day of caffeine exposure. Caffeine decreased amphetamine-induced rearing in males, but had no effect in females; however, this behavioral effect was not accompanied by changes in striatal c-Fos, which was increased by amphetamine but not altered by caffeine. No effects of caffeine were observed on novel object recognition or elevated plus maze behavior. However, in the L/D test, there was a sex by caffeine interaction on time spent in the light driven by a caffeine-induced increase in light time in the males but not the females. On the pretest day of the FST, sex by caffeine interactions were observed for swimming and struggling; caffeine decreased struggling behavior and increased swimming behavior in males and caffeine-treated females demonstrated significantly more struggling and significantly less swimming than caffeine-treated males. A similar pattern was observed on the test day in which caffeine decreased immobility overall and increased swimming. These data reveal sex dependent effects of caffeine on behavior in adolescent rats. PMID:26850920

    Full Text Available The effects of postnatal amitraz exposure on physical and behavioral parameters were studied in Wistar rats, whose lactating dams received the pesticide (10 mg/kg orally on days 1, 4, 7, 10, 13, 16 and 19 of lactation; control dams received distilled water (1 ml/kg on the same days. A total of 18 different litters (9 of them control and 9 experimental born after a 21-day gestation were used. The results showed that the median effective time (ET50 for fur development, eye opening, testis descent and onset of the startle response were increased in rats postnatally exposed to amitraz (2.7, 15.1, 21.6 and 15.3 days, respectively compared to those of the control pups (1.8, 14.0, 19.9 and 12.9 days, respectively. The ages of incisor eruption, total unfolding of the external ears, vaginal and ear opening and the time taken to perform the grasping hindlimb reflex were not affected by amitraz exposure. Pups from dams treated with amitraz during lactation took more time (in seconds to perform the surface righting reflex on postnatal days (PND 3 (25.0 ± 2.0, 4 (12.3 ± 1.2 and 5 (8.7 ± 0.9 in relation to controls (10.6 ± 1.2; 4.5 ± 0.6 and 3.4 ± 0.4, respectively; the climbing response was not changed by amitraz. Postnatal amitraz exposure increased spontaneous motor activity of male and female pups in the open-field on PND 16 (140 ± 11 and 17 (124 ± 12, and 16 (104 ± 9, 17 (137 ± 9 and 18 (106 ± 8, respectively. Data on spontaneous motor activity of the control male and female pups were 59 ± 11 and 69 ± 10 for days 16 and 17 and 49 ± 9, 48 ± 7 and 56 ± 7 for days 16, 17 and 18, respectively. Some qualitative differences were also observed in spontaneous motor behavior; thus, raising the head, shoulder and pelvis matured one or two days later in the amitraz-treated offspring. Postnatal amitraz exposure did not change locomotion and rearing frequencies or immobility time in the open-field on PND 30, 60 and 90. The present findings indicate

    1994-12-01

    This study was designed to investigate the effect of T. serrulatus scorpion venom on dopamine (DA) and gamma amino butyric acid (GABA) concentrations in different regions of the brain. The ratio of homovanillic acid (HVA) to DA, and the glutamic acid decarboxylase (GAD) activity were determined following intravenous or intracerebral venom injections. The increase in the HVA/DA ratio in the striatum after i.v. or intrastriatal injection could indicate an increase in DA turnover. One hour after i.v. injection of the venom GAD activity was shown to be decreased in the striatum and hypothalamus. After 24 hr GAD activity increased in the striatum and decreased in the hypothalamus and brain stem. These results could indicate different effects of the venom on the GABA system in different areas of the brain. After intrastriatal injection of the scorpion venom, the animals showed stereotyped behavior and rotation activity. Following intrahippocampal injection, myoclonus and orofacial automatisms, which constitute pro-convulsive signals, were observed. These behavioral alterations could be, at least in part, related to the GABA and dopamine alterations caused by the venom, since stereotypy, circling behavior and convulsions are dependent on dopamine and/or GABA.

  5. Effect of concentration gradient on the anodic behavior of tungsten

    International Nuclear Information System (INIS)

    Potentiodynamic and potentiostatic polarization experiments, the electrochemical impedance spectroscopy, the rotating disk electrode technique, and surface pH measurements were used to study the effect of tungstate ions on the anodic behavior of tungsten (W). Deliberately added tungstate ions, which are also tungsten dissolution products, were found to decrease the anodic currents at around the point of zero charge, increase the anodic currents in the neutral to weakly basic range and have no effect on the anodic currents in the strongly basic conditions. This variable effect was attributed to the competition between the stabilization of the tungsten oxide due to higher concentration of the dissolution products next to the metal surface and the stabilization of the local pH as a result of the enhanced polymerization reactions of the tungstate species. The surface pH measurements showed that the polymerization reactions kept the W surface pH higher (i.e. closer to the bulk pH) in the absence of a pH buffer in the neutral and weakly basic solutions. The tungstate ion was considered as a potentially useful additive in W chemical mechanical polishing (CMP) slurries, since this ion could increase the stability of the oxide phase to be removed by polishing and serve as a pH buffering agent

    Parenting behaviors have received ample support as a mediator of the relationship between maternal affect and child behavior problems. The majority of these research efforts were based on a uni-dimensional conceptualization of maternal mood, even though decades of theory and research suggest that mood is multidimensional. We examined the mediating…

    Full Text Available Therelationship between leader and followers plays a vital role, particularly ineducational institutions where a keen understanding of human character and highlevel of social interaction ought to be facilitated. For this reason, in starkcontrast to contemporary leaders who see people only as units of production orexpendable resources in a profit and loss statement, servant leadership focuseson meeting the needs of followers, making them reach their maximum potentialand so perform optimally in order to achieve organizational goals andobjectives. This study examines theeffects of servant leadership behaviors of private college principals onteachers’ organizationalcitizenship behavior and job performance. Using 300 respondents from theprivate education institutes in Turkey, servant leadership behavior is examinedfor its indirect effects on organizational citizenship behavior and jobperformance by its impact on organizational justice. Organizational justiceacts as a mediator between the variables in question. All the results are insupport of the studied mediation effects. Implications of the findings andsuggestions for future research are discussed

    Full Text Available The field of animal personality is interested in decomposing behaviors into different levels of variation, with its present focus on the ecological and evolutionary causes and consequences of expressed variation. Recently the role of the social environment, i.e. social partners, has been suggested to affect behavioral variation and induce selection on animal personality. Social partner effects exist because characters of social partners (e.g. size, behavior, affect the behavioral expression of a focal individual. Here, we 1 first review the proximate mechanisms underlying the social partner effects on behavioral expression and the timescales at which such effects might take place. We then 2 discuss how within- and among-individual variation in single behaviors and covariation between multiple behaviors, caused by social partners, can carry-over to non-social behaviors expressed outside the social context. Finally, we 3 highlight evolutionary consequences of social carry-over effects to non-social behaviors and 4 suggest study designs and statistical approaches which can be applied to study the nature and evolutionary consequences of social carry-over effects on non-social behaviors. Understanding the proximate mechanisms underpinning the social partner effects is important since it opens a door for deeper understanding of how social environments can affect behavioral variation and covariation at multiple levels, and the evolution of non-social behaviors (i.e. exploration, activity, boldness that are affected by social interactions.

    Full Text Available Background: Breast cancer is the most common cancer in women. Surgical treatment of breast cancer may cause body image alterations. The purpose of the current study was to examine the effects of cognitive behavioral counseling on body image among Iranian women with primary breast cancer. Methods: In this quasi-experimental designed study, 72 patients diagnosed as breast cancer and surgically treated were enrolled in Isfahan, Iran. The patients were entered the study by convenience sampling method and were randomly di-vided in two groups of intervention (n = 32 and control (n = 40. The intervention group received consultation based on Ellis rational emotive behavior therapy (REBT method for 6 sessions during 3 weeks. The control group did not re-ceive any consultation Paired t-test was used to compare the changes in groups and independent t-test was conducted to compare two groups. The average values represented as mean ± standard deviation. Results: Before the study, the body image score was not significantly different between the intervention (16 97 ± 5 44 and control (15 95 ± 4 66 groups (t = 0 86, P = 0 395. The body image score was significantly lower in the interven-tion group (9 03 ± 6 11 compared to control group (17 18 ± 5 27 after the intervention (t = -6 07, P < 0 001. Conclusions: Since a woman′s body image influences her breast cancer treatment decision, oncology professionals need to recognize the value of a woman′s favorite about appearance and body image. This study emphasizes the impor-tance of offering consultation in breast cancer patients.

    Two dosages of Smokeless Tobacco (ST) extract were given to gravid Sprague-Dawley rats by oral gavage on gestational days (GD) 6-20. The low dosage contained ST extract equivalent to 1.33 mg/kg nicotine (STD-1), and the high dosage contained ST extract equivalent to 4.0 mg/kg nicotine (STD-2). Dams were dosed three times daily at 8 a.m., 11 a.m., and 2 p.m., thus providing total daily nicotine equivalent dosages of 4 mg/kg/day and 12 mg/kg/day. Controls received equivalent amounts of distilled water by gavage. Dams were allowed to deliver and all experimental pups were fostered to control mothers. On postnatal day 1 (PND 1) litters were culled to 4 +/- 1 females and 4 +/- 1 males. Weights, physical landmark development, and behavioral performance of pups were monitored during pre- and post-weaning periods. Behavioral tests included: surface righting, negative geotaxis, swimming development, open-field activity, active avoidance in shuttle box, and Cincinnati swimming maze. Our results show that the STD-2 dose resulted in reduced maternal weight gain. Offspring weights were reduced in a dose-related manner, with the most consistent weight deficits seen in the STD-2 group until PND29. Consistent STD-1 weight deficits were seen up to PND 8. The incidence of deaths was increased in the STD-2 dosage group. No significant treatment-related differences were observed in development of physical landmarks. Male STD-2 pups righted faster than controls, and significant differences were noted in swimming development with the STD-1 group of pups performing less effectively than controls. Activity levels, assessed during both pre- and post-weaning periods were not affected. No treatment-related differences were seen in the active avoidance shuttle box or Cincinnati swimming maze tests, which assessed learning. Female brain weights were reduced in the STD-1 treatment group. PMID:8336679

  16. La doping effect on TZM alloy oxidation behavior

    International Nuclear Information System (INIS)

    Highlights: • The oxidation can be resisted by doping La into TZM alloy. • La doped TZM alloy has more compact organization. • It can rise the starting temperature of severe oxidation reaction by more than 50 °C. • Effectively slow down the oxidation rate. • Provide guidance for experiments of improving high-temperature oxidation resistance. - Abstract: Powder metallurgy methods were utilized to prepare lanthanum-doped (La-TZM) and traditional TZM alloy plates. High temperature oxidation experiments along with the differential thermal analysis were employed to study the oxidation behavior of the two kinds of TZM alloys. An extremely volatile oxide layer was generated on the surface of traditional TZM alloy plates when the oxidation started. Molybdenum oxide volatilization exposed the alloy matrix, which was gradually corroded by oxygen, losing its quality with serious surface degradation. The La-TZM alloy has a more compact structure due to the lanthanum doping. The minute lanthanum oxide particles are pinned at the grain boundaries and refine the grains. Oxide layer generated on the matrix surface can form a compact coating, which effectively blocks the surface from being corroded by oxidation. The oxidation resistance of La-TZM alloys has been enhanced, expanding its application range

    Among natural biological flocks/swarms or mass social activities, when the collective behavior of the followers has been dominated by the direction or opinion of one leader group, it seems difficult for later-coming leaders to reverse the orientation of the mass followers, especially when they are in quantitative minority. This paper, however, reports a counter-intuitive phenomenon, i.e. Following the Later-coming Minority, provided that the later-comers obey a favorable distribution pattern that enables them to spread their influence to as many followers as possible within a given time and to be dense enough to govern these local followers they can influence directly from the beginning. We introduce a discriminant index to quantify the whole group's orientation under competing leaderships, with which the eventual orientation of the mass followers can be predicted before launching the real dynamical procedure. From the application point of view, this leadership effectiveness index also helps us to design an economical way for the minority later-coming leaders to defeat the dominating majority leaders solely by optimizing their spatial distribution pattern provided that the premeditated goal is available. Our investigation provides insights into effective leadership in biological systems with meaningful implications for social and industrial applications.

    Male, BALB/c mice were injected intraperitoneally with ethyl alcohol (ethanol) in dosages of 0, 0.03, 0.1, 0.3, 1.0, or 3.0 g/kg and then placed in a temperature gradient that permitted the measurement of preferred ambient temperature (Ta). The 3 g/kg dosage of ethanol resulted in a slight lowering of the preferred Ta during the first 30 min of placement in the gradient. However, there was no overall statistically significant effect of alcohol dosage on preferred Ta. In another experiment, BALB/c mice were treated with the aforementioned ethanol dosages while metabolic rate (MR), evaporative water loss (EWL), and colonic temperature were measured 60 min post-injection at Ta's of 20, 30, and 35 C a dosage of 3 g/kg caused a significant decrease in MR, EWL, and colonic temperature. At a Ta of 30 C this same dosage caused significant reduction in colonic temperature, however; at Ta of 35 C ethanol had no effect on these parameters. In spite of the significant decrease in colonic temperature at a Ta of 30 C, which approximates the normal preferred Ta, the behavioral thermal preference was marginally affected. It is not clear whether or not ethanol injection results in a decrease in the set-point body temperature.

    Full Text Available Background: Febrile convulsions (FCs, occurring between 6 months and 6 years of age is the most common seizure disorder during childhood. The febrile response is thought to be mediated by the release of pyrogenic cytokines, such as tumor necrosis factor and interleukin-1 (IL-1. There is a significant relationship between genetic components for susceptibility of FCs and different report mutation. We investigated association between two polymorphisms in the tumor necrosis factor (TNF-α promoter region (G-308A, C-850T and FCs in the southwest area of Iran. Materials and Methods: In this matched case-control study, 100 patients with febrile convulsion as case group and 130 healthy children as control group were enrolled in the study. Peripheral blood samples were collected and DNA was extracted by standard phenol-chloroform method. The genotype and allele frequencies of TNF- α polymorphisms in case and control groups were determined by using PCR-RFLP (polymerase chain reaction restriction fragment length polymorphism method. Statistical analysis was done using Chi-square test. Results: The average age of case and control groups were 3.4 ± 1.4 and 3.4 ± 1.2 years, respectively. There was no significant difference between age and sex in both the groups (P > 0.05. A family history of febrile convulsion was detected in 44% of patients. Moreover, the simple febrile convulsion was detected in 85% of the case group. Conclusion: RFLP analysis of TNF- α promoter region polymorphisms, considering P = 0.146 and P = 0.084 for G-308A and C-850T, respectively, showed no correlation between TNF- α polymorphisms and predisposition to simple febrile, based on the kind of convulsion (atypical and simple febrile convulsion. We found a significant relation between genotype distribution of G-308A and atypical febrile convulsion in case group (P = 0.04.

    Maternal smoking during pregnancy (SDP) is associated with increased risk of externalizing and internalizing behaviors in offspring. Two explanations (not mutually exclusive) for this association are direct causal effects of maternal SDP and the effects of genetic and environmental factors common to parents and offspring which increase smoking as well as problem behaviors. Here, we examined the associations between parental SDP and mother rated offspring externalizing and internalizing behaviors (rated by the Child Behavior Checklist/2-3) at age three in a population-based sample of Dutch twins (N = 15,228 pairs). First, as a greater effect of maternal than of paternal SDP is consistent with a causal effect of maternal SDP, we compared the effects of maternal and paternal SDP. Second, as a beneficial effect of quitting smoking before pregnancy is consistent with the causal effect, we compared the effects of SDP in mothers who quit smoking before pregnancy, and mothers who continued to smoke during pregnancy. All mothers were established smokers before their pregnancy. The results indicated a greater effect of maternal SDP, compared to paternal SDP, for externalizing, aggression, overactive and withdrawn behavior. Quitting smoking was associated with less externalizing, overactive behavior, aggression, and oppositional behavior, but had no effect on internalizing, anxious depression, or withdrawn behavior. We conclude that these results are consistent with a causal, but small, effect of smoking on externalizing problems at age 3. The results do not support a causal effect of maternal SDP on internalizing behaviors. PMID:26324285

Informationsuch as age, sex, developmental status, type of FC, family history of seizure,urine sampling method, and the results of antibiograms were recorded.ResultsThe age distribution of 137 patients (82 boys, 55 girls was as follows: 1-6 monthsof age, 1 infant (0.7%; 6-12 months, 21 infants (15.3%; 1-3 years, 75 (54.8%;3-5 years, 30 (21.9%; and more than 5 years, 10 (7.3%. Three out of the 82boys and 6 out of the 55 girls had UTI (3.7% vs. 10.9%, total, 6.6%. The agedistribution of these 9 patients was as follows: 1-6 months, 1 patient (11.1%;7-12 months, 5 (55.6%; and 1-3 years, 3 (33.3%. The relative incidence of UTIwas 6.6%. The most common organisms causing infections were Escherichiacoli in 8 and Proteus spp., in 1 patient (88.8% vs. 11.1%. Simple FC was seenin all 9 patients with UTI.ConclusionIn this study, the relative frequency of UTI among children with FC was 6.6%and this frequency was higher that the incidence of UTI in girls and boys(3-5% and 1%, respectively. Therefore, we recommend that UTI should beconsidered as an important cause of FC in children.

    Full Text Available Multiple sclerosis (MS is prominent among central nervous system diseases. It affects chiefly young people and almost inevitably results in disability. In the past decade, there has been an upward trend for the prevalence of MS worldwide; in particular, the higher prevalence of this disease has been registered in the Moscow Region, which is associated with both an objective increase in its morbidity and improvement of specialized care to the population in the region. MS is characterized by a variety of clinical manifestations. However, paroxysmal disturbances are referred to as the rare symptoms of MS: the incidence of epileptic seizures in this condition is 0.89 to 7.5% according to the literature data. In addition to the clinical form of MS, there are its rare malignant atypical forms that also include its pseudotumoral form characterized by intrinsic neuroimaging and clinical signs that are different from the classical form of MS and another abnormality of the central nervous system. The pseudotumoral form of MS is characterized by the development of acute focal demyelination that appears as a large focus of an increased magnetic resonance signal with perifocal edema as evidenced by magnetic resonance imaging. A pseudotumoral focus of demyelination can occur both at the onset of MS and during its recurrent course. The atypical onset of MS is a special challenge because of diagnostic problems, which may lead to erroneous therapeutic policy and have a negative impact on the late prognosis of the disease. The authors provide a clinical case of the pseudotumoral form of MS with convulsive seizures at the onset of demyelinating disease. The problems of diagnosis and therapeutic approaches are discussed.

In the past, decreased levels of magnesium in serum and CSF of patients with FC were reported. The purpose of this study was to identify the possible role of magnesium in febrile seizures in children. Identifying this condition, we may control seizures and also prevent subsequent convulsion. In this cross-sectional study, inclusion criteria were the existence of convulsion due to fever and exclusion criteria were having a known neurological disease which could induce a seizure, and children younger than one month. In each group (cases include children with febrile convulsion and controls include febrile children without convulsion, Mg was measured in blood, and cerebrospinal fluid of 90 children and then they were compared. The data were analyzed by SPSS (α=0.05. The mean serum and CSF levels of Mg in case and control groups were equal (P<0.87 and P<0.22 respectively. There was no difference between two groups in terms of sex, but mean age was significantly different (P<0.003. There was not an association between serum and CSF levels of magnesium and the presence of FC. Therefore, it’s not suggested to measure the level of magnesium in serum or CSF in children with fever routinely.

    Full Text Available Abstract Background A detailed behavioral profile associated with focal congenital malformation of the ventromedial prefrontal cortex (vmPFC has not been reported previously. Here we describe a 14 year-old boy, B.W., with neurological and psychiatric sequelae stemming from focal cortical malformation of the left vmPFC. Case Presentation B.W.'s behavior has been characterized through extensive review Patience of clinical and personal records along with behavioral and neuropsychological testing. A central feature of the behavioral profile is severe antisocial behavior. He is aggressive, manipulative, and callous; features consistent with psychopathy. Other problems include: egocentricity, impulsivity, hyperactivity, lack of empathy, lack of respect for authority, impaired moral judgment, an inability to plan ahead, and poor frustration tolerance. Conclusions The vmPFC has a profound contribution to the development of human prosocial behavior. B.W. demonstrates how a congenital lesion to this cortical region severely disrupts this process.

    Simple Summary Chicks require heat to maintain body temperature during the first weeks after hatch. Heat is normally provided by use of heating lamps or whole-house heating, but an alternative is dark brooders, i.e. horizontal heating elements equipped with curtains. The effects of providing layer chicks with dark brooders during the brooding period on behavior and fearfulness were investigated. Brooders resulted in chicks showing less locomotive activity, feather pecking and fleeing. Also, a long-term reduction of fearfulness in brooder birds was found. Results support the suggestion that rearing with dark brooders can be a successful method of reducing or preventing some of the major welfare problems in layers. Abstract Chicks require heat to maintain body temperature during the first weeks after hatch. This may be provided by dark brooders; i.e., horizontal heating elements equipped with curtains. The objective was to test effects of rearing layer chicks with dark brooders on time budget and fearfulness. Behavioral observations were performed during the first six weeks of age. Three different fear tests were conducted when the birds were age 3–6, 14–15 and 26–28 weeks. During the first four days, brooder chicks rested more than control chicks whereas they spent less time drinking, feather pecking and on locomotion (p ≤ 0.009). On days 16, 23, 30 and 42, brooder chicks spent less time on feather pecking, locomotion and fleeing (p ≤ 0.01) whereas foraging and dust bathing occurred more often on day 42 (p ≤ 0.032). Brooder birds had shorter durations of tonic immobility at all ages (p = 0.0032), moved closer to the novel object at age 15 weeks (p < 0.0001), and had shorter latencies to initiate locomotion in the open-field test at age 28 weeks (p < 0.0001). Results support the suggestion that dark brooders can be a successful method of reducing or preventing fear and feather pecking in layers. PMID:26751482

    Full Text Available This study aims to investigate the effects of utilitarian and hedonic values on young consumers’ satisfaction and behavioral intentions in fast-food and fast-casual restaurant sectors comparatively. Also this study investigates which value component (utilitarian or hedonic is more effective on satisfaction and behavioral intentions. The results show that utilitarian and hedonic values have significant effects on satisfaction and behavioral intentions for both fast-food and fast-casual restaurant sectors. Additionally, satisfaction has an influence on behavioral intentions in fast-food restaurant sector, but does not have a significant effect in fast-casual restaurant sector. Moreover, associations between hedonic value with satisfaction and behavioral intentions are significantly different between fast-food and fast-casual restaurant sectors. On the other hand, associations between utilitarian value with satisfaction and behavioral intentions and association between satisfactions with behavioral intentions are not significantly different between fast-food and fast-casual restaurant sectors.

  4. Occurrence, behavior and effects of nanoparticles in the environment.

    Nowack, Bernd; Bucheli, Thomas D

    2007-11-01

    The increasing use of engineered nanoparticles (NP) in industrial and household applications will very likely lead to the release of such materials into the environment. Assessing the risks of these NP in the environment requires an understanding of their mobility, reactivity, ecotoxicity and persistency. This review presents an overview of the classes of NP relevant to the environment and summarizes their formation, emission, occurrence and fate in the environment. The engineered NP are thereby compared to natural products such as soot and organic colloids. To date only few quantitative analytical techniques for measuring NP in natural systems are available, which results in a serious lack of information about their occurrence in the environment. Results from ecotoxicological studies show that certain NP have effects on organisms under environmental conditions, though mostly at elevated concentrations. The next step towards an assessment of the risks of NP in the environment should therefore be to estimate the exposure to the different NP. It is also important to notice that most NP in technical applications are functionalized and therefore studies using pristine NP may not be relevant for assessing the behavior of the NP actually used.

  5. EFFECTS OF ROCK BEHAVIOR AND STRESS CONDITIONON FIELD STRESS DETERMINATION

    Institute of Scientific and Technical Information of China (English)

    D.H.(Steve)Zou

    1995-01-01

    Non-consistency of stress results is often observed during field measurements. In some cases, even the measurements are made at the same location in a massive rockmass, the results can vary widely. In order to solve the problem, extensive research has been carried out to study the major factors which may affect stress determination. They include the rock behaviour and the stress state. For rocks showing non-isotropic behaviour, the values of Young's modulus and Poisson ratio vary with the orientation of loading and measurement. Stress condition in the rock affects the rock behaviour. Furthermore, the loading condition on rock samples during laboratory tests is different from in the field and therefore the determined elastic constants may not represent the field condition. In general, the Young's modulus may depend on the orientation, the loading path, the stress magnitude and the stress ratio. This paper examines in detail the effects of those factors, especially for rocks showing transversely isotropic behaviour. It is found that the discrepancy of stress results from fieldts in this type of rock is mainly due to over simplification of the rock behavior and inadequate use of elastic constants of the rock during stress calculation. A case study is given, which indicates the significance of these factors and demonstrates the proper procedure for stress calculation from

    2014-04-01

    Although recent emotion regulation research has identified effective regulatory strategies that participants can employ during single experimental sessions, a critical but unresolved question is whether one can increase the efficacy with which one can deploy these strategies through repeated practice. To address this issue, we focused on one strategy, reappraisal, which involves cognitively reframing affective events in ways that modulate one's emotional response to them. With a commonly used reappraisal task, we assessed the behavioral correlates of four laboratory sessions of guided practice in down-regulating responses to aversive photos. Two groups received practice in one of two types of reappraisal tactics: psychological distancing and reinterpretation. A third no-regulation control group viewed images in each session without instructions to regulate. Three key findings were observed. First, both distancing and reinterpretation training resulted in reductions over time in self-reported negative affect. Second, distancing participants also showed a reduction over time in negative affect on baseline trials in which they responded naturally. Only distancing group participants showed such a reduction over and above the reduction observed in the no-regulation control group, indicating that it was not attributable to habituation. Third, only participants who distanced reported less perceived stress in their daily lives. The present results provide the first evidence for the longitudinal trainability of reappraisal in healthy adults using short courses of reappraisal practice, particularly using psychological distancing.

  7. Effect of Crystal Orientation on Nanoindentation Behavior in Magnesium

    Somekawa, Hidetoshi; Schuh, Christopher A.

    2016-04-01

    The effect of crystal orientation on nanoindentation behavior at both quasi-static and high strain rates was investigated using single-crystalline magnesium oriented in basal and prismatic configurations. Both the basal and prismatic planes had similar activation volumes, 55 and 73b 3 for deformation at room temperature, as well as a small temperature dependence up to 423 K (150 °C). Microstructural observations beneath the indentations revealed that { 10bar{1}2 } type deformation twins were formed in both orientations irrespective of testing temperature. With twins forming beneath the indenter and multiple orientations of loading, it is believed that cross-slip and/or multiple slip are likely rate-controlling for global deformation, which also aligns with observations on nanoindentation of polycrystalline coarse-grained magnesium. The locations of the twins were consistent with expectations based on indentation mechanics as assessed by finite element simulations. The finite element simulations also predicted that an indenter tip with a shaper tip radius would tend to promote { 10bar{1}2 } twins.

  8. Effect of Electrode Configuration on Nitric Oxide Gas Sensor Behavior

    2015-09-01

    Full Text Available The influence of electrode configuration on the impedancemetric response of nitric oxide (NO gas sensors was investigated for solid electrochemical cells [Au/yttria-stabilized zirconia (YSZ/Au]. Fabrication of the sensors was carried out at 1050 °C in order to establish a porous YSZ electrolyte that enabled gas diffusion. Two electrode configurations were studied where Au wire electrodes were either embedded within or wrapped around the YSZ electrolyte. The electrical response of the sensors was collected via impedance spectroscopy under various operating conditions where gas concentrations ranged from 0 to 100 ppm NO and 1%–18% O2 at temperatures varying from 600 to 700 °C. Gas diffusion appeared to be a rate-limiting mechanism in sensors where the electrode configuration resulted in longer diffusion pathways. The temperature dependence of the NO sensors studied was independent of the electrode configuration. Analysis of the impedance data, along with equivalent circuit modeling indicated the electrode configuration of the sensor effected gas and ionic transport pathways, capacitance behavior, and NO sensitivity.

    This research examined the impact of operant reinforcement of positive self-descriptive behavior on the self-concepts and classroom behavior of 60 fifth-grade students. Three groups of 10 male and 10 female low self-concept students wrote a series of eight essays describing their school performance. The first group (P) received written reinforcement for positive self-descriptions of their school performance. The second group (G) received an equal number of reinforcements for general statements. The third group (C) received no reinforcement for written statements. Three areas of self-concept were measured with the Primary Self-Concept Inventory: personal-self, social-self, and intellectual-self. A frequency count was also made of nine classroom behaviors thought to be influenced by self-concept. The P group displayed increases in the frequency of positive self-descriptive statement and in intellectual self-concept but no changes in personal self-concept, social self-concept, or the nine classroom behaviors. The G and C groups showed no change in self-description, self-concept, or the nine classroom behaviors. PMID:894617

    Full Text Available Cay Anderson-Hanley, Kimberly Tureck, Robyn L Schneiderman Department of Psychology, Union College, Schenectady, NY, USA Abstract: Autism is a neurodevelopmental disorder that leads to impairment in social skills and delay in language development, and results in repetitive behaviors and restricted interests that impede academic and social involvement. Physical exercise has been shown to decrease repetitive behaviors in autistic children and improve cognitive function across the life-span. Exergaming combines physical and mental exercise simultaneously by linking physical activity movements to video game control and may yield better compliance with exercise. In this investigation, two pilot studies explored the potential behavioral and cognitive benefits of exergaming. In Pilot I, twelve children with autism spectrum disorders completed a control task and an acute bout of Dance Dance Revolution (DDR; in Pilot II, ten additional youths completed an acute bout of cyber cycling. Repetitive behaviors and executive function were measured before and after each activity. Repetitive behaviors significantly decreased, while performance on Digits Backwards improved following the exergaming conditions compared with the control condition. Additional research is needed to replicate these findings, and to explore the application of exergaming for the management of behavioral disturbance and to increase cognitive control in children on the autism spectrum.

    2012-03-01

    Full Text Available Abstract Background Behavioral interventions typically focus on objective behavioral endpoints like weight loss and smoking cessation. In reality, though, achieving full behavior change is a complex process in which several steps towards success are taken. Any progress in this process may also be considered as a beneficial outcome of the intervention, assuming that this increases the likelihood to achieve successful behavior change eventually. Until recently, there has been little consideration about whether partial behavior change at follow-up should be incorporated in cost-effectiveness analyses (CEAs. The aim of this explorative review is to identify CEAs of behavioral interventions in which cognitive outcome measures of behavior change are analyzed. Methods Data sources were searched for publications before May 2011. Results Twelve studies were found eligible for inclusion. Two different approaches were found: three studies calculated separate incremental cost-effectiveness ratios for cognitive outcome measures, and one study modeled partial behavior change into the final outcome. Both approaches rely on the assumption, be it implicitly or explicitly, that changes in cognitive outcome measures are predictive of future behavior change and may affect CEA outcomes. Conclusion Potential value of cognitive states in CEA, as a way to account for partial behavior change, is to some extent recognized but not (yet integrated in the field. In conclusion, CEAs should consider, and where appropriate incorporate measures of partial behavior change when reporting effectiveness and hence cost-effectiveness.

    Barrish, H H; Saunders, M; Wolf, M M

    1969-01-01

    Out-of-seat and talking-out behaviors were studied in a regular fourth-grade class that included several "problem children". After baseline rates of the inappropriate behaviors were obtained, the class was divided into two teams "to play a game". Each out-of-seat and talking-out response by an individual child resulted in a mark being placed on the chalkboard, which meant a possible loss of privileges by all members of the student's team. In this manner a contingency was arranged for the inappropriate behavior of each child while the consequence (possible loss of privileges) of the child's behavior was shared by all members of this team as a group. The privileges were events which are available in almost every classroom, such as extra recess, first to line up for lunch, time for special projects, stars and name tags, as well as winning the game. The individual contingencies for the group consequences were successfully applied first during math period and then during reading period. The experimental analysis involved elements of both reversal and multiple baseline designs. PMID:16795208

    The NASA Decadal Survey (2011), Recapturing a Future for Space Exploration: Life and Physical Sciences Research for a New Era, emphasized the importance of expanding NASA life sciences research to long duration, rodent experiments on the International Space Station (ISS). To accomplish this objective, flight hardware, operations, and science capabilities supporting mouse studies in space were developed at NASA Ames Research Center. The first flight experiment carrying mice, Rodent Research Hardware and Operations Validation (Rodent Research-1), was launched on Sept 21, 2014 in an unmanned Dragon Capsule, SpaceX4, exposing the mice to a total of 37 days in space. Ground control groups were maintained in environmental chambers at Kennedy Space Center. Mouse health and behavior were monitored for the duration of the experiment via video streaming. Here we present behavioral analysis of two groups of five C57BL/6 female adult mice viewed via fixed camera views compared with identically housed Ground Controls. Flight (Flt) and Ground Control (GC) mice exhibited the same range of behaviors, including eating, drinking, exploratory behavior, self- and allo-grooming, and social interactions at similar or greater levels of occurrence. Mice propelled themselves freely and actively throughout the Habitat using their forelimbs to push off or by floating from one cage area to another, and they quickly learned to anchor themselves using tails and/or paws. Overall activity was greater in Flt as compared to GC mice, with spontaneous ambulatory behavior including the development of organized ‘circling’ or ‘race-tracking’ behavior that emerged within the first few days of flight and encompassed the primary dark cycle activity for the remainder of the experiment. We quantified the bout frequency, duration and rate of circling with respect to characteristic behaviors observed in the varying stages of the progressive development of circling: flipping utilizing two sides of the

    2011-01-01

    Autism is a neurodevelopmental disorder that leads to impairment in social skills and delay in language development, and results in repetitive behaviors and restricted interests that impede academic and social involvement. Physical exercise has been shown to decrease repetitive behaviors in autistic children and improve cognitive function across the life-span. Exergaming combines physical and mental exercise simultaneously by linking physical activity movements to video game control and may yield better compliance with exercise. In this investigation, two pilot studies explored the potential behavioral and cognitive benefits of exergaming. In Pilot I, twelve children with autism spectrum disorders completed a control task and an acute bout of Dance Dance Revolution (DDR); in Pilot II, ten additional youths completed an acute bout of cyber cycling. Repetitive behaviors and executive function were measured before and after each activity. Repetitive behaviors significantly decreased, while performance on Digits Backwards improved following the exergaming conditions compared with the control condition. Additional research is needed to replicate these findings, and to explore the application of exergaming for the management of behavioral disturbance and to increase cognitive control in children on the autism spectrum.

    Environmental enrichment increases adult hippocampal neurogenesis and alters hippocampal-dependent behavior in rodents. To investigate a causal link between these two observations, we analyzed the effect of enrichment on spatial learning and anxiety-like behavior while blocking adult hippocampal neurogenesis. We report that environmental enrichment alters behavior in mice regardless of their hippocampal neurogenic capability, providing evidence that the newborn cells do not mediate these effects of enrichment.

    Five experiments demonstrate that brands cause priming effects (i.e., behavioral effects consistent with those implied by the brand), whereas slogans cause reverse priming effects (i.e., behavioral effects opposite to those implied by the slogan). For instance, exposure to the retailer brand name "Walmart," typically associated with saving money, reduces subsequent spending, whereas exposure to the Walmart slogan, "Save money. Live better," increases it. Slogans cause reverse priming effects ...

  20. Effect of I125 on oxidation behavior of lipoprotein subpopulations

    International Nuclear Information System (INIS)

    Lipoproteins play a central role in lipid metabolism. They serve as a transport vehicle for cholesterol and triglycerides keeping them in plasma in solution. Lipoproteins are characterized by the content of specific apoproteins and differences in the hydrated density ranges. Moreover, they are distinguished by electrophoretic mobility and other characteristics as high and low-density lipoproteins, respectively lipoprotein (a). More specifically, HDL is classified into HDL2 and HDL3. In atherogenesis, lipoproteins are considered to play a key-role. Oxidatively modified LDL is selectively taken up via scavenger receptors of the macrophage-monocyte system. These cells are transformed into foam cells promoting atherogenesis in vessels in the subendothelial space. Oxidized HDL essentially appears to loose its protective effects on LDL and its beneficial function in reverse cholesterol transport. Thus, it turns proatherogenic. The effects various species of free radicals exert on lipoproteins are the reason for this oxidative modification. Thyroid function also influences lipoproteins in a complex manner. Based on their hydrated density ranges, lipoprotein subpopulations were fractionated and isolated via isopycnic density gradient ultracentrifugation. After investigation of the general oxidation behavior, initiated by addition of CuSO4 to the isolated samples of HDL3, HDL2, LDL and Lp(a), the influence of different activities of radioiodine-125 on the kinetics of the formation of conjugated dienes was assessed. This was achieved by coincubation of plasma with I125. The spectrophotometrical measurement of the concentration of conjugated dienes in the course of CuSO4-induced lipid peroxidation leads to measurable changes in absorption at 234 nm. These changes in absorption over time result in a characteristically shaped curve graphically plotted. The shape of these curves mirrors different indicators of lipid peroxidation.

    expression was significantly decreased by everolimus (10{sup -5} M) in FC. Percentage of RAM-11 positive area exhibited a reduction trend within sections stented with EES compared to unstented proximal sections at 60 days (p = 0.09). Conclusion: Everolimus, a potent anti-proliferative agent used in drug-eluting stents and bioresorbable vascular scaffolds, may inhibit atheroma progression and/or promote atheroma stabilization through diminished viability of FC, decreased matrix degradation, and reduced pro-inflammatory cytokine secretion. Executive Summary: We explored the effects of everolimus on the behavior of human THP1 macrophage-derived foam cells in culture, including cell viability, mRNA levels, and pro-inflammatory cytokine production. We conclude that everolimus, a potent anti-proliferative agent used in drug-eluting stents/bioresorbable vascular scaffolds, may potentially inhibit atheroma progression and/or promote atheroma stabilization through diminished viability of foam cells, decreased matrix degradation, and reduced pro-inflammatory cytokine secretion.

    Weaver, Jennifer M; Schofield, Thomas J

    2015-02-01

    Using data from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development, we examined children's internalizing and externalizing behavior problems from age 5 to 15 years in relation to whether they had experienced a parental divorce. Children from divorced families had more behavior problems compared with a propensity-score-matched sample of children from intact families, according to both teachers and mothers. They exhibited more internalizing and externalizing problems at the first assessment after the parents' separation and at the last available assessment (age 11 years for teacher reports, or 15 years for mother reports). Divorce also predicted both short-term and long-term rank-order increases in behavior problems. Associations between divorce and child behavior problems were moderated by family income (assessed before the divorce) such that children from families with higher incomes prior to the separation had fewer internalizing problems than children from families with lower incomes prior to the separation. Higher levels of predivorce maternal sensitivity and child IQ also functioned as protective factors for children of divorce. Mediation analyses showed that children were more likely to exhibit behavior problems after the divorce if their postdivorce home environment was less supportive and stimulating, their mother was less sensitive and more depressed, and their household income was lower. We discuss avenues for intervention, particularly efforts to improve the quality of home environments in divorced families. PMID:25419913

    2016-07-01

    Disruptions can prevent the classroom from being an effective learning environment. The Good Behavior Game (GBG) is a group contingency that has been proven to effectively prevent disruptions and increase engagement. However, the traditional methods of the GBG include teacher scanning for negative student behaviors, and may not align with Positive Behavioral Interventions and Supports (PBIS), which is becoming widely adopted in many schools. Extending the findings of Wright and McCurdy, the current study compared the effects of the GBG and a positive version of the GBG, called the Caught Being Good Game (CBGG), on student behavior, including engagement and off-task behaviors, as well as teachers' use of positive and negative statements. Results showed both the GBG and the CBGG improved student behavior, with data not clearly indicating one was superior. Neither intervention led to an increase in positive teacher statements. Implications for teachers and suggestions for further research are discussed. PMID:27118053

    large global models because of their high computational demand. We compare an easily integrated, computationally efficient behavioral algorithm known as Gilliam's rule against the solution from a life-history optimization. The approximation takes into account only the current conditions to optimize...... behavior; the so-called "myopic approximation", "short sighted", or "static optimization". We explore the performance of the myopic approximation with diel vertical migration (DVM) as an example of a daily routine, a behavior with seasonal dependence that trades off predation risk with foraging...... opportunities in aquatic environments. The myopic approximation proves to be a robust replacement for the life-history optimization, deviating only up to 25% in regions of strong seasonality. The myopic approximation has additional advantages in that it can readily accommodate density dependence and inter...

    A poly(4-acrylamidosalicylic acid) gel (PASA gel) exhibits multiple phases as characterized by distinct degrees of swelling; the gel can take one of four different swelling values, but none of the intermediate values. The gel has remarkable memory: the phase behavior of the gel depends on whether the gel has experienced the most swollen phase or the most collapsed phase in the immediate past. The information is stored and reversibly erased in the form of a macroscopic phase transition behavior. The structure factors corresponding to these four phases were obtained by SANS, which indicated the presence of characteristic structures depending on pH and temperature, particularly in the shrunken state.

    Adult day services (ADS) are an increasingly popular option for caregivers of people with dementia, but there is little research on the effects of activities on the behavior and mood of the client. This study examines participation by 94 individuals in different types of adult day-care activities and their association with changes in behavior and psychological symptoms of dementia (BPSD) for the client during a three-month span. Three domains of BPSD were examined: restless behaviors, mood behaviors, and positive behaviors. Using growth curve modeling, results show that the restless and mood behavior domains, on average, were stable over three months, whereas positive behaviors increased. For all three behavior domains there were individual differences in average level of BPSD. Average rate of change for individuals also varied from the mean for restless and mood behaviors. Physical activities, social activities, engaging activities, and watching and listening activities, along with a day-care dosage variable, were used as covariates to explain these individual differences in change. Engaging activities explained some of the individual variance for restless behaviors; as individuals increased one increment in engaging activities, they had fewer restless behavior problems over time. These results suggest that some features of programming may be related to improvements in restless behavior. PMID:16003933

    Research on video games has yielded consistent findings that violent video games increase aggression and decrease prosocial behavior. However, these studies typically examined single-player games. Of interest is the effect of cooperative play in a violent video game on subsequent cooperative or competitive behavior. Participants played Halo II (a first-person shooter game) cooperatively or competitively and then completed a modified prisoner's dilemma task to assess competitive and cooperative behavior. Compared with the competitive play conditions, players in the cooperative condition engaged in more tit-for-tat behaviors-a pattern of behavior that typically precedes cooperative behavior. The social context of game play influenced subsequent behavior more than the content of the game that was played. PMID:22489544

  14. Effects of Prosocial, Neutral, and Violent Video Games on Children's Helpful and Hurtful Behaviors.

    Recent research reveals that playing prosocial video games increases prosocial cognitions, positive affect, and helpful behaviors [Gentile et al., 2009; Greitemeyer and Osswald, 2009, 2010, 2011]. These results are consistent with the social-cognitive models of social behavior such as the general learning model [Buckley and Anderson, 2006]. However, no experimental studies have examined such effects on children. Previous research on violent video games suggests that short-term effects of video games are largely based on priming of existing behavioral scripts. Thus, it is unclear whether younger children will show similar effects. This research had 9-14 years olds play a prosocial, neutral, or violent video game, and assessed helpful and hurtful behaviors simultaneously through a new tangram measure. Prosocial games increased helpful and decreased hurtful behavior, whereas violent games had the opposite effects. PMID:25363697

    To clarify the pathophysiological role of homocarnosine in the cerebrospinal fluid (CSF) in children, homocarnosine levels in CSF were determined in patients with epilepsy (32 cases), febrile convulsion (5 cases) and meningitis (42 cases) with a high speed amino acid autoanalyzer (Hitachi Co.). Mean homocarnosine levels in CSF of controlled epileptic children, uncontrolled epileptic children and febrile convulsion cases were 0.61 +/- 0.25 mumol/dl, 1.03 +/- 0.37 mumol/dl and 1.09 +/- 0.04 mumol/dl, respectively. High homocarnosine levels in CSF of children with uncontrolled epilepsy or febrile convulsion may indicate the reduced turnover rate from homocarnosine to GABA. In patients with meningitis, the unconscious states were accompanied by significantly lower homocarnosine levels in CSF (0.39 +/- 0.20 mumol/dl) than those in the patients with clear conscious states (0.9 +/- 0.31 mumol/dl, however, in patients with clear conscious states homocarnosine in CSF were almost the same as those of normal children (0.89 +/- 0.23 mumol/dl). These data suggest that homocarnosine in CSF might be related to the convulsive tendency and consciousness. PMID:7283086

    Objective To explore the efficacy and safety of midazolam nasal drip in the treatment of children’s febrile convulsion. Methods 42 children who suffered from febrile convulsion were randomly divided into two groups(the treament group and the control group). 0.2 mg/kg midazolam nasal drip was delivered to each member of the treament group,while 0.3~0.5 mg/kg diazepam was given to each member of the control group by intravenous injection. Compared and evaluated the control time,effective rate and safefy regarding treament of children’s febrile convulsion with midazolam nasal drip. Results Effective rate of treament group was 85.7%,while the control group was 90.5%. These weren’t significantly different from each other(P > 0.05). The control time of the treament group was(6.2 ±1.6)min,while the control group was(8.10 ±0.9)min(P<0.05). Both groups showed no obvious adverse reacitons. Conclusion It is effective and convenient to treat children’s febrile convulsion with midazolam nasal drip.%目的:探讨咪达唑仑鼻腔给药治疗小儿高热惊厥的有效性和安全性。方法选取小儿热性惊厥患儿42例,随机分为治疗组和对照组各21例。治疗组鼻腔内滴入咪达唑仑0.2 mg/kg,对照组给予地西泮0.3~0.5 mg/kg静脉缓慢推注。比较分析两组患儿的惊厥控制时间、有效率及安全性。结果治疗组和对照组有效率分别为85.7%和90.5%,组间比较差异无统计学意义(P>0.05);治疗组患儿从到达医院急诊科至惊厥控制所用时间为(6.2±1.6)min,对照组为(8.1±0.9)min,差异具有统计学意义(P<0.05)。两组均未发现明显不良反应。结论咪达唑仑鼻腔滴入可以有效地控制小儿热性惊厥,且更方便快捷。

  17. Effects of Nicotine on the Neurophysiological and Behavioral Effects of Ketamine in Humans

    Full Text Available Background: N-methyl-D-aspartate (NMDA receptor hypofunction has been implicated in the pathophysiology of schizophrenia and its associated neurocognitive impairments. The high rate of cigarette smoking in schizophrenia raises questions about how nicotine modulates putative NMDA receptor hypofunction in the illness. Accordingly, we examined the modulatory effects of brain nicotinic acetylcholine receptor (nAChR stimulation on NMDA receptor hypofunction by examining the interactive effects of nicotine, a nAChR agonist, and ketamine, a noncompetitive NMDA receptor antagonist, on behavioral and neurophysiological measures in healthy human volunteers.Methods: From an initial sample of 17 subjects (age range 18 - 55 years, 8 subjects successfully completed 4 test sessions, each separated by at least 3 days, during which they received ketamine or placebo and two injections of nicotine or placebo in a double-blind, counterbalanced manner. Schizophrenia-like effects (PANSS, perceptual alterations (CADSS, subjective effects (VAS and auditory event-related brain potentials (mismatch negativity, P300 were assessed during each test session.Results: Consistent with existing studies, ketamine induced transient schizophrenia-like behavioral effects. P300 was reduced and delayed by ketamine regardless of whether it was elicited by a target or novel stimulus, while nicotine only reduced the amplitude of P3a. Nicotine did not rescue P300 from the effects of ketamine; the interactions of ketamine and nicotine were not significant. While nicotine significantly reduced MMN amplitude, ketamine did not. Conclusion: Nicotine failed to modulate ketamine-induced schizophrenia-like effects in this preliminary study. Interestingly, ketamine reduced P3b amplitude and nicotine reduced P3a amplitude, suggesting independent roles of NMDA receptor and nAChR in the generation of P3b and P3a, respectively.

    The long-term impact of early stress on behavior and emotions is well documented in humans, and can be modeled in experimental animals. In mice, maternal separation during early postnatal development induces poor and disorganized maternal care, and results in behavioral deficits that persist through adulthood. Here, we examined the long-term effect of unpredictable maternal separation combined with maternal stress on behavior and its transmissibility. We report that unpredictable maternal sep...
