ABSTRACT

Resumo O jogo de tabuleiro Violetas: cinema & ação no enfrentamento da violência contra a mulher, forjado a partir da priorização das características libertárias do lúdico, ambienta lutas para a conquista da cidadania. O objetivo do artigo foi analisar a jogabilidade do Violetas quanto ao entendimento das regras, ao envolvimento das(os) jogadoras(es), à mecânica e ao design do jogo; e avaliar comparativamente as dimensões da jogabilidade, das emoções e da aprendizagem como expressões da ludicidade. Pesquisa de métodos mistos, em etapas: a) aperfeiçoamento da jogabilidade: oficina com 12 especialistas; testes de usabilidade (33 participantes); análise de conteúdo; b) avaliação da ludicidade: questionários a 78 participantes, teste não paramétrico U de Mann-Whitney para comparação dos grupos de variáveis. Os aspectos da jogabilidade obtiveram graus de concordância elevados entre as/os participantes. As variáveis da jogabilidade assumiram valor igual em relação ao grupo da aprendizagem, ambos significativamente diferentes de um grupo 2, das emoções sentidas na partida. No Violetas, o entrelaçamento da jogabilidade com os componentes formativos da aprendizagem viabilizam a criação de um campo simbólico, desafiador e afetivo em que a imaginação, a interação, a tensão e o interesse das(os) jogadoras(es) se manifestam durante as partidas.


Abstract The board game Violets: cinema and action in combating violence against women was developed prioritising the liberating features of play to offer a setting for struggles to secure citizenship. The objective of the article was to examine the gameplay of Violets as regards players' understanding of the rules and engagement, and the game's mechanics and design; and to evaluate gameplay, emotions and learning comparatively as dimensions of play. This mixed method study proceeded in stages: a) perfecting gameplay: a workshop with 12 experts, usability tests with 33 participants and content analysis; and b) evaluating play: questionnaires for 78 participants and non-parametric Mann-Whitney U-test comparing groups of variables. Agreement among participants on aspects of gameplay was high. The group of gameplay variables returned values equal to those of the learning group; both differed significantly from the group for emotions felt while playing. In Violets, the interweave of gameplay with the formative, learning components set up a challenging, affective, symbolic field where players' imagination, interaction, tension and interest were expressed during play.

ABSTRACT

Screening the reference genes that were stably expressed under different light intensities for Viola yedoensis could provide reference for the related molecular research. In this study, 11 candidate reference genes were detected by RT-qPCR for tissues of V. yedoensis treated with different light intensities. Ge Norm, Norm Finder, Best Keeper, and Ref Finder website were used to comprehensively evaluate the reference genes, and verify the stability of the reference gene based on CAT1. Finally, the ideal reference gene was determined. The results showed that CYP, Actin, and SAMDC had small Ct value ranges and stable expression. Ge Norm demonstrated that CYP, SAMDC, and Actin were suitable reference genes. Norm Finder showed that the expression of α-TUB was the most stable. Best Keeper recommended CYP, Actin, and SAMDC as reference genes. Ref Finder assessed that SAMDC, CYP, α-TUB, and Actin had better stability, while GAPDH had the worst stability. The expression trend of CAT1 gene was consistent when calibrated with SAMDC, CYP, and Actin, while it was quite different from that calibrated with GAPDH. In summary, SAMDC, CYP, and Actin can be used as ideal reference genes for the gene expression profiling of V. yedoensis under different light intensities.

ABSTRACT

The current study was conducted to explore the effects of light intensity in cultivating environment on the cleaning away heat property of Viola yedoensis. In the present study, we established the acute inflammation model of ICR mice by injecting carrageenan. We compared the effects of V. yedoensis grown under different light intensities(100%, 80%, 50%, 35% and 5% of full sunlight) on mice body temperature, thermal radiation and the swelling degree of foot tissue before and after modeling observing by thermal infrared imaging technique and weighing method. The changes of energy metabolism related enzymes in liver were detected by enzyme-linked immunosorbent assay(ELISA). In addition, the effects of V. yedoensis grown under different light intensities on human lung cancer cell A549 proliferation were explored with MTT method. The results showed that the body temperature of all groups of mice in V. yedoensis group were significantly lower than that of the blank group, except 5% full sunlight group, and the body temperature declined in positive proportion to light intensity. V. yedoensis group could alleviate foot swelling, reduce SDH activity in liver tissue(especially 100% full sunlight group and 80% full sunlight group were significantly lower than model group), and the degree of alleviating and reducing was positively correlated with light intensity. There was no significant difference in the activity of Na~+-K~+-ATPase and Ca~(2+)-Mg~(2+)-ATPase in liver tissue among treatments. The contents of IL-1β, IL-6, TNF-α, PGE_2 in foot tissue of mice in V. yedoensis groups were significantly lower than those in model group. Among them, the lowest levels of IL-1β, IL-6, TNF-α, PGE_2 were found in 80% full sunlight group, and there was no significant difference in TNF-α among different groups. The effects of V. yedoensis aqueous extract on A549 cell line proliferation inhibition rate increased with the light intensities of V. yedoensis cultivating environment. And the effects of V. yedoensis grown under 100% of full sunlight showed significantly higher A549 cell line proliferation inhibition rate compared with other groups(P<0.05). In summary, the light intensity of V. yedoensis cultivating environment is positively correlated with the cleaning away heat property of V. yedoensis, which conforms to the "light-cold and heat property" hypothesis,The V. yedoensis should be planted under full light according.

ABSTRACT

Light energy is an important factor affecting plant growth. The hypothesis of "light-cold and heat property" holds that the original plants of traditional Chinese medicines(TCM) with cold property can obtain more energy to maintain growth in high light intensity environment, whereas the original plants of TCM with heat property prefer weak light environment. The current experiment investigated the effects of different light intensities on primary metabolites levels, energy levels, cell apoptosis, and leaves ultrastructure of Viola yedoensis, the original plants of TCM Violae Herba with cold property. There were five treatment groups of V. yedoensis, which was planted under Li1(8 500 lx),Li2(7 250 lx),Li3(6 000 lx),Li4(4 750 lx),Li5(3 500 lx)LEDs light intensity conditions, respectively. After harvest, primary metabolites levels, contents of ATP, ADP, AMP, activities of ATP synthesis and hydrolysis related enzyme, as well as cell apoptosis activation degree were measured, and transmission electron microscopy technique was used to observe leaves ultrastructure. The results showed that the total sugar, total protein, contents of ATP, ADP and AMP, activities of NADH dehydrogenase, cytochrome C reductase, ATP synthase and ATP hydrolase were positively correlated with light intensities(P<0.05). The crude fat content, activities of SDH and CCO enzyme showed a trend of increasing first and then decreasing, the highest value were found in Li2 group and Li3 group respectively(P<0.05). The vitality of caspase-3 and caspase-9 was negatively correlated with light intensities(P<0.05). The structure of chloroplast and mitochondria were normal and intact in Li1-Li3 groups, and the damage degree of Li4 and Li5 groups increased with the decrease of light intensities. The analysis of results indicated that the structure of chloroplast and mitochondria of V. yedoensis is normal under the light intensity of 6 000-8 500 lx, which can obtain more energy to maintain its growth and metabolism. When the light intensity is lower than 4 750 lx, the chloroplast morphology and mitochondrial membrane are damaged, affecting the metabolism of material and energy. There was no significant difference in energy charge of V. yedoensis in the light intensity range of 3 500~8 500 lx. The effect of light intensity on energy metabolism of V. yedoensis accords with the hypothesis of "light-cold and heat property".

ABSTRACT

Regulator of calcineurin 1 (RCAN1) can be induced by an intracellular calcium increase and oxidative stress, which are characteristic features of temporal lobe epilepsy. Thus, we investigated the spatiotemporal expression and cellular localization of RCAN1 protein and mRNA in the mouse hippocampus after pilocarpine-induced status epilepticus (SE). Male C57BL/6 mice were given pilocarpine hydrochloride (280 mg/kg, i.p.) and allowed to develop 2 h of SE. Then the animals were given diazepam (10 mg/kg, i.p.) to stop the seizures and sacrificed at 1, 3, 7, 14, or 28 day after SE. Cresyl violet staining showed that pilocarpine-induced SE resulted in cell death in the CA1 and CA3 subfields of the hippocampus from 3 day after SE. RCAN1 immunoreactivity showed that RCAN1 was mainly expressed in neurons in the shammanipulated hippocampi. At 1 day after SE, RCAN1 expression became detected in hippocampal neuropils. However, RCAN1 signals were markedly enhanced in cells with stellate morphology at 3 and 7 day after SE, which were confirmed to be reactive astrocytes, but not microglia by double immunofluorescence. In addition, real-time reverse transcriptase–polymerase chain reaction showed a significant upregulation of RCAN1 isoform 4 (RCAN1-4) mRNA in the SE-induced hippocampi. Finally, in situ hybridization with immunohistochemistry revealed astrocytic expression of RCAN1-4 after SE. These results demonstrate astrocytic upregulation of RCAN1 and RCAN1-4 in the mouse hippocampus in the acute and subacute phases of epileptogenesis, providing foundational information for the potential role of RCAN1 in reactive astrocytes during epileptogenesis.

ABSTRACT

The study is aimed to investigate the effects of light intensities on growth,photosynthetic physiology,antioxidant systems and chemical composition of Viola yedoensis and provide cultivation references for V.yedoensis.Five groups of V.yedoensis were planted under five light intensities conditions,namely 100%,80%,50%,35%,5%of full sunlight,and then morphological index,growth,chlorophyll fluorescence parameters,photosynthetic parameters and antioxidant enzyme system indexes were measured during harvest.The results showed that there was no significant difference in the biomass of V.yedoensis among 35% -100%full sunlight,but the biomass of those were significantly higher than that in the 5%full sunlight treatment(P<0.05).The net photosynthetic rate,transpiration rate,stomatal conductance,intercellular CO_2 concentration and water use efficiency increased firstly and then decreased with the decrease of light intensity;F_m,F_v/F_mand Yield in 5% full sunlight treatment were significantly lower than those in the other four groups(P<0.05).The structure of chloroplast was normal under light intensity ranged from 50%to 100% full sunlight.The lamellar concentration of chloroplast matrix decreased and the starch granules decreased in 35% full sunlight treatment,and the margin of lamellar layer of chloroplast and substrate were blurred,and the starch granules were small and the number of starch granules decreased significantly under 5% full sunlight.MDA content in 5%full sunlight treatment was significantly higher than those in the other four groups(P<0.05).The total coumarin content and total flavonoid content decreased with the decrease of light intensity.In summary,the light in-tensity range suitable for the growth of V.yedoensis is wide(ranging from 35% to 100% full sunlight).The content of flavonoids and coumarins is positively correlated with light intensity.

ABSTRACT

Primary cutaneous anaplastic large cell lymphoma (C-ALCL) is rare among skin malignancies. C-ALCL usually manifests as reddish or violet nodules. Surgical excision or radiation therapy is generally considered as first-line therapy, but a clinically aggressive disease may require multiagent chemotherapy. Establishing a proper diagnosis of C-ALCL is challenging but should be made to avoid inappropriate treatment and its consequences. The authors report a case of medically resolved C-ALCL in an 81-year-old man presented with well-defined nodular lesions on the forehead.

ABSTRACT

In the developed and developing world, opioid consumption in combination with alcohol has become one of the substances abused. In this experiment, we examined the effects of alcohol, morphine, and morphine+alcohol combination on cognitive functions and neuroinflammatory responses in the medial prefrontal cortex (mPFC) of juvenile male rats. Alcohol (1.0 ml of 15% v/v ethanol twice daily, subcutaneously, 7 hours apart), morphine (0.5 ml/kg of 0.4 mg/kg morphine chlorate twice daily, subcutaneously, 7 hours apart), morphine+alcohol co-treatment (0.5 ml/kg of 0.4 mg/kg morphine chlorate+1.0 ml of 15% v/v ethanol twice daily, subcutaneously, 7 hours apart) were administered for 21 days. Treatment with morphine+alcohol significantly impairs cognition functions in the Morris water maze, passive avoidance, and novel object recognition tests, furthermore, the treatment significantly increased the quantitative count of astrocytic cells and also conferred marked neuronal cell death in the mPFC, which were studied by glial fibrillary acidic protein immunochemistry for astrocytes and Cresyl violet for Nissl's substance distribution in neurons respectively. These results suggest that alcohol, morphine, and morphine+alcohol co-treatment may trigger cognitive deficits and neuroinflammatory responses in the brain.

ABSTRACT

Status epilepticus is the most common serious neurological condition triggered by abnormal electrical activity, leading to severe and widespread cell loss in the brain. Lithium has been one of the main drugs used for the treatment of bipolar disorder for decades, and its anticonvulsant and neuroprotective properties have been described in several neurological disease models. However, the therapeutic mechanisms underlying lithium's actions remain poorly understood. The muscarinic receptor agonist pilocarpine is used to induce status epilepticus, which is followed by hippocampal damage. The present study was designed to investigate the effects of lithium post-treatment on seizure susceptibility and hippocampal neuropathological changes following pilocarpine-induced status epilepticus. Status epilepticus was induced by administration of pilocarpine hydrochloride (320 mg/kg, i.p.) in C57BL/6 mice at 8 weeks of age. Lithium (80 mg/kg, i.p.) was administered 15 minutes after the pilocarpine injection. After the lithium injection, status epilepticus onset time and mortality were recorded. Lithium significantly delayed the onset time of status epilepticus and reduced mortality compared to the vehicle-treated group. Moreover, lithium effectively blocked pilocarpine-induced neuronal death in the hippocampus as estimated by cresyl violet and Fluoro-Jade B staining. However, lithium did not reduce glial activation following pilocarpine-induced status epilepticus. These results suggest that lithium has a neuroprotective effect and would be useful in the treatment of neurological disorders, in particular status epilepticus.

ABSTRACT

Cerebrospinal fluid (CSF) contains several molecules which are essential for neurogenesis. Human dental pulp stem cells (hDPSCs) are putatively neural crest cell-derived that can differentiate into neurons and glial cells under appropriate neurotrophic factors. The aim of this study was to induce differentiation of hDPSCs into neuroglial phenotypes using retinoic acid (RA) and CSF. The hDPSCs from an impacted third molar were isolated by mechanical and digestion and cultured. The cells have treated by 10⁻⁷µM RA (RA group) for 8 days, 10% CSF (CSF group) for 8 days and RA with CSF for 8 days (RA/CSF group). Nestin, microtubule-associated protein 2 (MAP2), and glial fibrillary acidic protein immunostaining were used to examine the differentiated cells. Axonal outgrowth was detected using Bielschowsky's silver impregnation method and Nissl bodies were stained in differentiated cells by Cresyl violet. The morphology of differentiated cells in treated groups was significantly changed after 3–5 days. The results of immunocytochemistry showed the presence of neuroprogenitor marker nestin was seen in all groups. However, the high percentage of nestin positive cells and MAP2, as mature neural markers, were observed at the pre-induction and induction stage, respectively. Nissl bodies were detected as dark-blue particles in the cytoplasm of treated cells. Our findings showed the RA as pre-inducer and CSF as inducer for using in vitro differentiation of neuron-like cells and neuroglial cells from hDPSCs.

ABSTRACT

In this study, we observed the ontogenetic changes in glucose transporter 3 (GLUT3) immunoreactivity, a major neuronal GLUT, in the dentate gyrus of mouse brains at various ages: postnatal day (P) 1, 7, 14, 28, and 56. At P1, cresyl violet staining showed abundant neurons in the dentate gyrus, whereas the granule cell layer was ill-defined. At P7, the granule cell layer was observed, and cresyl violet-positive cells were dispersed throughout the polymorphic layer. At P14, the granule cell layer was well-defined, and cresyl violet positive cells were detected abundantly in the polymorphic layer. At P28 and P56, cresyl violet-positive cells were observed in the granule cell layer, as well as in the polymorphic layer. At P1, GLUT3 immunoreactivity was detected in the dentate gyrus. At P7, GLUT3 immunoreactive cells were scattered in the polymorphic and molecular layer. However, at P14, GLUT3 immunoreactivity was observed in the polymorphic layer as well as subgranular zone of the dentate gyrus. At P28, GLUT3 immunoreactivity was detected in the polymorphic layer of the dentate gyrus. At P56, GLUT3 immunoreactivity was observed predominantly in the subgranular zone of the dentate gyrus. GLUT3 immunoreactive cells were mainly colocalized with doublecortin, which is a marker for differentiated neuroblasts, in the polymorphic layer and subgranular zone of dentate gyrus at P14 and P56. These results suggest that the expression of GLUT3 is closely associated with postnatal development of the dentate gyrus and adult neurogenesis.

ABSTRACT

BACKGROUND AND OBJECTIVES: MicroRNA 145 is known to be responsible for cellular proliferation, and its enhanced expression reportedly inhibits the retardation of vascular smooth muscle cell growth specifically. In this study, we developed a microRNA 145 nanoparticle immobilized, hyaluronic acid (HA)-coated stent. MATERIALS AND METHODS: For the gene therapy, we used disulfide cross-linked low molecular polyethylenimine as the carrier. The microRNA 145 was labeled with YOYO-1 and the fluorescent microscopy images were obtained. The release of microRNA 145 from the stent was measured with an ultra violet spectrophotometer. The downstream targeting of the c-Myc protein and green fluorescent protein was determined by Western blotting. Finally, we deployed microRNA 145/ssPEI nanoparticles immobilized on HA-coated stents in the balloon-injured external iliac artery in a rabbit restenosis model. RESULTS: Cellular viability of the nanoparticle-immobilized surface tested using A10 vascular smooth muscle cells showed that MSN exhibited negligible cytotoxicity. In addition, microRNA 145 and downstream signaling proteins were identified by western blots with smooth muscle cell (SMC) lysates from the transfected A10 cell, as the molecular mechanism for decreased SMC proliferation that results in the inhibition of in-stent restenosis. MicroRNA 145 released from the stent suppressed the growth of the smooth muscle at the peri-stent implantation area, resulting in the prevention of restenosis at the post-implantation. We investigated the qualitative analyses of in-stent restenosis in the rabbit model using micro-computed tomography imaging and histological staining. CONCLUSION: MicroRNA 145-eluting stent mitigated in-stent restenosis efficiently with no side effects and can be considered a successful substitute to the current drug-eluting stent.

ABSTRACT

Anthocyanins are water soluble plant pigments which are responsible for the blue, red, pink, violet colors in several plant organs such as flowers, fruits, leaves and roots. In recent years, anthocyanin-rich foods have been favored as dietary supplements and health care products due to diverse biological activities of anthocyanins including antioxidant, anti-allergic, anti-diabetic, anti-microbial, anti-cancer and preventing cardiovascular disease. High-performance countercurrent chromatography (HPCCC) coupled with reversed-phase medium pressure liquid chromatography (RP MPLC) method was applied for the rapid and efficient isolation of cyanidin 3-glucoside (C3G) and peonidin 3-glucoside (P3G) from black rice (Oryza sativa L., Poaceae). The crude black rice extract (500 mg) was subjected to HPCCC using two-phase solvent system composed of tert-butyl methyl ether/n-butanol/acetonitrile/0.01% trifluoroacetic acid (TBME/B/A/0.01% TFA, 1 : 3 : 1 : 5, v/v, flow rate - 4.5 mL/min, reversed phase mode) to give enriched anthocyanin extract (37.4 mg), and enriched anthocyanin extract was sequentially chromatographed on RP-MPLC to yield C3G (16.5 mg) and P3G (8.7 mg). The recovery rate and purity of isolated C3G were 76.0% and 98.2%, respectively, and those of P3G were 58.3% and 96.3%, respectively. The present study indicates that HPCCC coupled with RP-MPLC method is more rapid and efficient than multi-step conventional column chromatography for the separation of anthocyanins.

ABSTRACT

We report on a case of torsion of an accessory spleen occurring in a 19-year-old female. She was admitted with a three-day history of left-upper quadrant pain that became slowly aggravated. On physical examination, left-side abdominal tenderness was observed, most markedly in the left upper quadrant, but no rebound tenderness was noted. Contrast-enhanced computed tomography (CT) scan showed a non-enhancing mass with a tubular vascular pedicle and normal enhancing spleen in the left upper abdomen. Doppler ultrasound showed no vascular flow within the hypoechoic mass in the left upper abdomen. Torsion of an accessory spleen was suspected, and emergent laparoscopic exploration was performed. Laparoscopic exploration showed a large rounded violet mass with a tw isted vascular pedicle, located anterior to the normal spleen. The mass was excised laparoscopically and then removed through a 2.5 cm extended incision of the left-sided trocar incision. Postoperative recovery was normal and she was discharged on the fifth postoperative day.

ABSTRACT

In this study, we identified the causative agent of stem-end rot in potatoes that were grown in Gangwon alpine areas of Korea in 2013. The disease symptoms included appearance of slightly sunken circular lesion with corky rot on the potato surface at the stem-end portion. The fungal species isolated from the infected potatoes were grown on potato dextrose agar and produced white aerial mycelia with dark violet pigments. The conidiophores were branched and monophialidic. The microconidia had ellipsoidal to cylindrical shapes and ranged from 2.6~11.4 x 1.9~3.5 microm in size. The macroconidia ranged from 12.7~24.7 x 2.7~3.6 microm in size and had slightly curved or fusiform shape with 2 to 5 septate. Chlamydospores ranged from 6.1~8.1 x 5.7~8.3 microm in size and were present singly or in pairs. The causal agent of potato stem-end rot was identified as Fusarium oxysporum by morphological characterization and by sequencing the internal transcribed spacer (ITS1 and ITS4) regions of rRNA. Artificial inoculation of the pathogen resulted in development of disease symptoms and the re-isolated pathogen showed characteristics of F. oxysporum. To the best of our knowledge, this is the first study to report that potato stem-end rot is caused by F. oxysporum in Korea.

ABSTRACT

Three cyclotides were isolated from the whole plant of Viola yedoensis in this study. The two, vary peptide E and cycloviolacin Y5, were previously reported, and a novel cycloviolacin VY1 was characterized according to the interpretation of MS/MS fragmentation of peptides which were produced from the reduced and alkylated parent peptide with the digestion of Endo Lys-C, trypsin and chymotrypsin, separately. The stability of remarkable resistance to proteolytic degradation by trypsin and chymotrypsin, and that of thermal denaturation was confirmed again. Besides, the IC50 value of cycloviolacin VY1 against influenza A H1N1 virus was (2.27 +/- 0.20) microg x mL(-1). It is the first cyclotide reported with anti-influenza A H1N1 virus activity in vitro assay.

ABSTRACT

Bacterial infection of the uterus in Hanwoo can kill embryos. Therefore, many antibiotics have been used to treat this infection in the uterus of repeat breeders. Incorrect use of antibiotics has led to resistance in bacteria. Natural compounds have used as substitutes for antibiotics because they are safe and have very mild side effects. This study was conducted to examine the antimicrobial effects of five extracts from medicinal plants including Humulus japonicas (Hj), Phelledendron amurense (Pa), Viola mandshurica (Vm), Carthamus tinctorius (Ct), and Chelidoni herba (Ch) on bacteria isolated from the uterus of Hanwoo using the paper disc diffusion method. Hj and Pa extracts had potent antimicrobial effects against Staphylococcus lentus, Streptococcus infantarius subsp. coli, and Bacillus pumilus. Pa had the greatest antimicrobial effect among the five medicinal plants and was effective against 19 types of bacteria from bovine uterus. Compared to Pa, Hj showed weaker antimicrobial effects on all the bacteria tested except Pseudomonas aeruginosa. Vm, Ct, and Ch also showed weak antimicrobial effects on the tested bacteria. The results obtained suggest that Hj and Pa are natural compounds suitable for treating bacterial infection in repeat breeders and improving conception rates of Hanwoo.

ABSTRACT

Aspirin (acetylsalicylic acid) is one of the most widely used therapeutic agents based on its pharmacological actions, including anti-inflammatory, analgesic, anti-pyretic, and anti-thrombotic effects. In this study, we investigated the effects of aspirin on seizure susceptibility and hippocampal neuropathology following pilocarpine-induced status epilepticus (SE). SE was induced by pilocarpine hydrochloride (280 mg/kg, i.p.) administration in C57BL/6 mice (aged 8 weeks). Aspirin was administered daily (15 mg/kg or 150 mg/kg, i.p.) for 10 days starting 3 days before SE, continuing until 6 days after SE. After pilocarpine injection, SE onset time and mortality were recorded. Neuronal cell death was examined using cresyl violet and Fluoro-Jade staining, and glial responses were observed 7 days post SE using immunohistochemistry. In the aspirin-treated group, the onset time of SE was significantly shortened and mortality was markedly increased compared to the control group. However, in this study, aspirin treatment did not affect SE-induced neuronal cell death or astroglial and microglial responses in the hippocampus. In conclusion, these results suggest that the safety of aspirin should be reevaluated in some patients, especially with neurological disorders such as temporal lobe epilepsy.
