Między spotkaniem a mijaniem. Rahel Varnhagen, Hannah Arendt, Judith Butler
Authors: Koper Beata
Published: October 2020

The article is an attempt at capturing the relationship between the lives and creative attitudes of Rahel Varnhagen, Hannah Arendt and Judith Butler. Starting with Varnhagen’s biography written by Arendt, the essay’s author wonders about the philosopher’s writing strategy. Instead of a classic reconstruction of life, the biographer offers a collage of excerpts from Rahel’s letters with extensive commentary. This form encourages one to read Rahel Varnhagen as a narration about the author and her own struggle with Jewish and female identity. The second relationship analysed in the essay is the impact of Hannah Arendt’s texts on Judith Butler’s writings. Despite the criticism of the philosopher’s writings, Arendt remains an unquestionable inspiration to Butler. The article also emphasises the differencebetween the theoreticians: Arendt uses the strategy of mimicry (writing about identity in the form of a German Jew’s biography), while Butler writes a politically-engaged text, exposing herself and her identity.
Epitafia dla romantyzmu polskiego na przełomie lat 80. i 90. XX wieku
Authors: Siatkowska-Callebat Kinga
Published: October 2020

The article is about three texts of Polish culture (a 1989 film by Tadeusz Konwicki, A Tale of Adam Mickiewicz’s ‘Forefathers’ Eve, based on Mickiewicz’s poem Dziady, and two novels: Rien ne va plus by Andrzej Bart, 1991 and List of the adulteresses. Travel prose by Jerzy Pilch, 1993) which seem to bid farewell to the long duration of Polish romanticism. The three works concur with Maria Janion’s thesis who heralded, in a democratic and independent Poland after the political changes of 1989, the twilight of the romantic paradigm as it had existed since the first half of the nineteenth century. A more detailed analysis of these cultural texts allows us to grasp the complexity and the ambiguity of the relationships that Konwicki, Bart and Pilch have with the romantic legacy.
Hannah Arendt i sobowtóry. Próba myślenia
Authors: Kuczyńska-Koschany Katarzyna
Published: October 2020

The essay discusses an issue that has not yet been studied separately: Hannah Arendt and her autobiographical crumbs scattered across other people’s biographies that she wrote and in her own biographies, both literary and cinematic. I called it an attempt at thinking, i.e. a synonym of a (biographical) essay. When Arendt writes about, e. g. Walter Benjamin or Rahel Varnhagen, she also – sometimes – writes about herself. When she smokes a cigarette in a specific way (rather than any other) or speaks German, she creates specific non-verbal doppelganger-like constructions.

Authors: Binkley Helen M. , Phillips Kristi L. , Wise Stephanie L.
Published: October 2020

Recognition of the physiological and psychological concerns associated with menopausal women is described. A review of the current literature regarding these conditions (vasomotor responses, insomnia, sarcopenia, osteoporosis, obesity, cardiovascular conditions, metabolic concerns, and psychological concerns) and how exercise impacts the conditions are discussed. Considerations of exercise for menopausal women are presented. General exercise programming and exercise adherence preferences are reviewed with recommendations for a variety of exercise types, exercise progressions, and exercise programming to meet the needs of the menopausal woman to improve overall health and well-being.
Blood Pressure Characteristics and Responses During Resistance Exercise
Authors: Apkarian Marc R.
Published: October 2020

Blood pressure changes acutely during resistance exercise. Continuous, beat-by-beat assessment provides detailed temporal resolution of blood pressure profiles, through techniques including intra-arterial catheterization, photoplethysmography, or applanation tonometry. However, noncontinuous measurements may be conducted before and after resistance exercise through auscultatory sphygmomanometry or oscillometry. Blood pressures tend to increase across repetitions within sets, influenced by load magnitude, repetitions and sets performed, muscle mass recruited, and rest periods; the highest pressures result from multi-joint, large muscle group exercises. Evaluation of such factors may facilitate better understanding of blood pressure responses to acute resistance exercise and influence program design considerations relative to anticipated hemodynamic changes.
OpBox: Open Source Tools for Simultaneous EEG and EMG Acquisition from Multiple Subjects

Published: October 2020

In vivoelectrophysiology experiments require the collection of data from multiple subjects, often for extended periods. Studying multiple subjects for extended periods can be made more efficient through simultaneous recordings, but scaling up recordings to accommodate larger numbers of subjects simultaneously requires coordination and consideration of costs and flexibility. To facilitate this process, we have developed OpBox, an open source set of tools to acquire electroencephalography (EEG) and electromyography (EMG) flexibly from multiple rodent subjects simultaneously. OpBox combines open source hardware and software with off-the-shelf components to create a system that costs less than commercial solutions ($500 per subject), and can be easily deployed for multiple subjects. Coded in MATLAB, OpBox scripts can simultaneously and flexibly collect and display multiple analog and digital data streams, for instance real-time EEG and EMG, event triggers from a behavioral system, and rotary encoder data. OpBox also calculates and displays real-time spectral representations and event-related potentials (ERPs). To verify the performance of our system, we compare our amplifiers with two other commercial amplifiers, a Grass P55 AC preamplifier and an Intan RHD2000-series amplifier. The OpBox amplifier performs comparably to commercial amplifiers for signal-to-noise ratios (SNRs), noise floors, and common mode rejection. We also demonstrate that our acquisition system can reliably record multichannel data from multiple subjects, and has been successfully tested with 12 subjects running simultaneously on a single standard desktop computer. Together, OpBox increases the flexibility and lowers the cost for simultaneous acquisition of electrophysiology data from multiple subjects.
Neuronal Activity Distributed in Multiple Cortical Areas during Voluntary Control of the Native Arm or a Brain-Computer Interface
Authors: Liu Zheng , Schieber Marc H.
Published: October 2020

Voluntary control of visually-guided upper extremity movements involves neuronal activity in multiple areas of the cerebral cortex. Studies of brain-computer interfaces (BCIs) that use spike recordings for input, however, have focused largely on activity in the region from which those neurons that directly control the BCI, which we call BCI units, are recorded. We hypothesized that just as voluntary control of the arm and hand involves activity in multiple cortical areas, so does voluntary control of a BCI. In two subjects (Macaca mulatta) performing a center-out task both with a hand-held joystick and with a BCI directly controlled by four primary motor cortex (M1) BCI units, we recorded the activity of other, non-BCI units in M1, dorsal premotor cortex (PMd) and ventral premotor cortex (PMv), primary somatosensory cortex (S1), dorsal posterior parietal cortex (dPPC), and the anterior intraparietal area (AIP). In most of these areas, non-BCI units were active in similar percentages and at similar modulation depths during both joystick and BCI trials. Both BCI and non-BCI units showed changes in preferred direction (PD). Additionally, the prevalence of effective connectivity between BCI and non-BCI units was similar during both tasks. The subject with better BCI performance showed increased percentages of modulated non-BCI units with increased modulation depth and increased effective connectivity during BCI as compared with joystick trials; such increases were not found in the subject with poorer BCI performance. During voluntary, closed-loop control, non-BCI units in a given cortical area may function similarly whether the effector is the native upper extremity or a BCI-controlled device.
Aging-Exacerbated Acute Axon and Myelin Injury Is Associated with Microglia-Derived Reactive Oxygen Species and Is Alleviated by the Generic Medication Indapamide

Published: October 2020

Age is a critical risk factor for many neurologic conditions, including progressive multiple sclerosis. Yet the mechanisms underlying the relationship are unknown. Using lysolecithin-induced demyelinating injury to the mouse spinal cord, we characterized the acute lesion and investigated the mechanisms of increased myelin and axon damage with age. We report exacerbated myelin and axon loss in middle-aged (8–10 months of age) compared with young (6 weeks of age) female C57BL/6 mice by 1–3 d of lesion evolution in the white matter. Transcriptomic analysis linked elevated injury to increased expression ofCybb, the gene encoding the catalytic subunit of NADPH oxidase gp91phox. Immunohistochemistry in male and femaleCx3cr1CreER/+:Rosa26tdTom/+mice for gp91phox revealed that the upregulation in middle-aged animals occurred primarily in microglia and not infiltrated monocyte-derived macrophages. Activated NADPH oxidase generates reactive oxygen species and elevated oxidative damage was corroborated by higher malondialdehyde immunoreactivity in lesions from middle-aged compared with young mice. From a previously conducted screen for generic drugs with antioxidant properties, we selected the antihypertensive CNS-penetrant medication indapamide for investigation. We report that indapamide reduced superoxide derived from microglia cultures and that treatment of middle-aged mice with indapamide was associated with a decrease in age-exacerbated lipid peroxidation, demyelination and axon loss. In summary, age-exacerbated acute injury following lysolecithin administration is mediated in part by microglia NADPH oxidase activation, and this is alleviated by the CNS-penetrant antioxidant, indapamide.

SIGNIFICANCE STATEMENTAge is associated with an increased risk for the development of several neurologic conditions including progressive multiple sclerosis, which is represented by substantial microglia activation. We demonstrate that in the lysolecithin demyelination model in young and middle-aged mice, the latter group developed greater acute axonal and myelin loss attributed to elevated oxidative stress through NADPH oxidase in lineage-traced microglia. We thus used a CNS-penetrant generic medication used in hypertension, indapamide, as we found it to have antioxidant properties in a previous drug screen. Following lysolecithin demyelination in middle-aged mice, indapamide treatment was associated with decreased oxidative stress and axon/myelin loss. We propose indapamide as a potential adjunctive therapy in aging-associated neurodegenerative conditions such as Alzheimer's disease and progressive multiple sclerosis.
Streaming Media’s Environmental Impact
Authors: Marks Laura U. , Clark Joseph , Livingston Jason , Oleksijczuk Denise , Hilderbrand Lucas
Published: October 2020

This group of articles, which arose from a panel planned for the 2020 annual meeting of members of the Society for Cinema and Media Studies, draws attention to an unpopular but inescapable issue: the adverse environmental effects of streaming media. Four of these brief interventions focus on streaming media’s carbon footprint, estimated by some to be 1 percent of global greenhouse gas emissions (The Shift Project 2019). This startling figure is rising at a calamitous rate as more people around the world stream more media at higher bandwidth—now exacerbated by the COVID-19 pandemic. Another factor in streaming media’s environmental impact is even less welcome: the deleterious effects of higher levels of electromagnetic frequencies that media corporations’ turn to fifth-generation (5G) wireless technology would exacerbate. These effects are well documented yet almost universally ignored. Despite all these findings, the notion abides that digital media are immaterial. Laura U. Marks introduces the research challenges involved in calculating the carbon footprint of streaming media and suggests actions consumers and media makers can take to mitigate this environmental threat. Joseph Clark discusses the implications of digitizing huge amounts of archival film and connects material histories of news film production, distribution, and preservation or disposal to contemporary issues of digital storage, streaming, and energy use, using the newsreel archive as a case study. Jason Livingston’s contribution expands on his droll and disturbing video lecture, which presents a speculative app for mobile phones that tracks streaming, correlates it to energy use and CO2 emissions, and suggests methods to mitigate usage. Denise Oleksijczuk introduces scientific research on the health and environmental impacts of high levels of electromagnetic frequencies and suggests ways, including creative practice, to break through the resistance to these findings among telecommunications companies, governments, and the public. Lucas Hilderbrand focuses on best practices in teaching: how to educate our students about these impacts, and how teachers can resist increasing pressures to use streaming-based pedagogical media. Many communities around the world already rely on low-tech media, of necessity, and are often extremely innovative in their use (Marks 2017). However, network and media corporations are aggressively marketing devices and streaming platforms in both “developed” and “developing” regions (Cisco 2020). Many of the latter regions depend on fossil fuels and cannot afford to prioritize renewable energy and efficient systems. Thus streaming media’s carbon footprint is not just a First World problem.
Drying influence on the development of cracks in Eucalyptus logs
Authors: Nascimento Thiago Magalhães do , Monteiro Thiago Campos , Baraúna Edy Eime Pereira , Moulin Jordão Cabral , Azevedo Alcinei Mistico
Published: October 2020

The aim of this study was to evaluate the effect of the moisture loss, diameter, and wood density on the appearance of surface cracks and end splits in Eucalyptus urophylla logs. The drying and emergence of defects were evaluated in 108 logs with diameters ranging from 60 mm to 150 mm from the initial moisture content to the equilibrium moisture content. The defects were measured during this time. Smaller diameter logs dried faster than larger diameter logs and took less time to reach the fiber saturation point. Surface cracks tended to develop during the loss of bound water. End splits developed during free water loss and continued to appear during bound water loss. Smaller diameters presented higher percentages of surface cracks compared with larger diameters, while larger diameters had a tendency for higher percentages of end splits compared with smaller diameters. The density did not influence the total emergence of end splits, but it did influence the total emergence of surface cracks, indicating a possibility for the selection of genetic material with lower tendency for cracking. Overall, the results reinforce the need to control drying at its beginning in order to decrease the risk of defects.
Preparation of composites from natural rubber and oil palm empty fruit bunch cellulose: Effect of cellulose morphology on properties
Authors: Fiorote José Antonio , Freire Alair Pereira , Rodrigues Dasciana de Sousa , Martins Maria Alice , Andreani Larissa , Valadares Leonardo Fonseca
Published: October 2020

Rubber tree and oil palm are industrial crops cultivated in the same climate and environment. These plants are used to prepare nanocomposites of natural rubber and cellulose from empty fruit bunches, an abundant residue in the palm oil industry. For this study, the cellulose particles were extracted from the bunches and subjected to enzymatic hydrolysis or microfibrillation to produce nanostructured particles. The nanoparticles were blended with natural rubber latex in an aqueous medium, and the mixture was dried. The properties of the nanocomposites were compared to those of pure natural rubber and unprocessed cellulose composites. The mechanical properties of the natural rubber can be modified by the cellulose content and morphology. As a consequence, it is possible to modulate the material properties by changing only the filler morphology. The use of microfibrillated cellulose had stronger reinforcement effects. The thermal properties of natural rubber were not affected by the addition of cellulose.
Cutting conditions and tool wear when machining wood-based materials
Authors: Chladil Josef , Sedlák Josef , Šebelová Eva Rybářová , Kučera Marián , Dado Miroslav
Published: October 2020

The article deals with data in the cutting process of wood-based materials. The cutting process influences the shape and dimensions of a cutting edge. The experiments were focused on monitoring the changes of the cutting edge in machining of particle board and the influence of cutting speed on the tool wear. Cutting tests were performed during milling at cutting rates in the range 7.95 to 17.9 m/s (477 to 1074 m/min), a depth of cut of 9.5 mm, and a tooth feed of 0.05 mm. The wear process of cutting wedge during particle board milling is characterized by a decrease in the cutting edge of insert blades. The comparative digital dial gauge was used for measurement of the cutting wedge recession. The course of the wear of wood based materials exhibited similarity in graphical representation with abrasive material cutting. The resulting dependency may be used for selection of the most suitable cutting conditions according to operator requirements.
Effects of pressure maintenance and strain maintenance during compression on subsequent dimensional stability and density after relaxation of blocks of chopped corn straw
Authors: Jia Honglei , Chen Tianyou , Zhang Shengwei , Sun Xumin , Yuan Hongfang
Published: October 2020

Chopped corn straw is a viscoelastic material that can rebound after compression. Pressure maintenance and strain maintenance are two key processes that enhance the dimensional stability of post-compression straw blocks. To study the effects of stabilization processes on the dimensions of post-compression straw blocks, the authors comparatively explored the relationships of strain and stress with time during constant-speed compression (CC), constant-speed compression followed by strain maintenance (CCS), constant-speed compression followed by pressure maintenance (CCP), and constant-speed compression, pressure maintenance followed by strain maintenance (CCPS), and uncovered the reasons for these relationships. The Burgers constitutive model fit well to the data during the pressure maintenance stage (R2>0.990), and the effects of pressure maintenance on strain and dimensional stability of post-compression straw blocks were investigated. The Wiechert model B (R2>0.990) was the constitutive model that best represented the strain maintenance stage. Additionally, the effects of strain maintenance during CCS and CCPS on relaxation rate and dimensional stability of post-compression straw were compared. The relaxation density of post-compression straw blocks was compared among different stabilization processes. The relaxation density of post-compression straw blocks was the largest after CCPS, followed by CCS and CCP.

Authors: Sarmiento Herencia Diego Alonso
Published: October 2020

El cine es un fenómeno con muchas aristas y, por ello, muy difícil de explicar. Los procesos involucrados, los distintos elementos que juegan papeles importantes en el desarrollo de historias —personajes, imágenes, sonidos, etc.— son tantos y tan variados que pretender explicarlos o definirlos sería una tarea ociosa. Sin embargo, al analizar la obra de un individuo, se obtienen luces sobre su manera de fabricar, su artesanía, y así logramos encontrar un lugar común y la posible teorización de un proceso. Este artículo apunta a descubrir las relaciones entre cine y literatura, desde un punto de vista estructural, utilizando la historia para determinar un lugar común y nacimiento de las técnicas que conforman el cine moderno.

El estatuto semántico de la representación del Diablo en el III Concilio Limense
Authors: Rodas-Bazán Dany
Published: October 2020

El rol de la Iglesia Católica, en el contexto de la conquista de América, ha sido descrito como una campaña que tuvo por objetivo único expandir la fe cristiana. No obstante, por medio de distintos discursos, que tienen como uno de sus ejes del concepto de Diablo, ayudaron en la consolidación de la Colonización. El siguiente artículo1 tiene por objetivo hallar las oposiciones semánticas  presentes en los sermones del Tercer Concilio Limense, con el fn de describir el nivel temático y, a partir de allí, poder interpretar las implicancias ideológicas en torno al concepto del Diablo. Se ha utilizado como metodología la teoría expresada por Joseph Courtés en Semiótica del discurso. Luego del análisis, se concluye que la imagen del Diablo, asociada a conceptos como alma, cuerpo, pecado, perdición, entre otras sirvió para convertir al indígena peruano en un sujeto colonizado.

Published: October 2020

Dental pain is the most common reason due to which patient seek dental treatment. Pain occur due to diseases involving pulp and periradicular tissues, as this tissues are richly innervated and have ample of blood supply. Also it is enclosed by surrounding tissues that are incapable of expanding, such as dentin and also has terminal blood flow and small-gauge circulatory access the periapex. All of these characteristics severely constrain the defensive capacity of the pulp tissue when faced with the different aggressions it may be subjected to. In addition to above mentioned characterstics, pulp tissue can also be affected by a retrograde infection, arising from the secondary canaliculi, from the periodontal ligament or from the apex during the course of periodontitis. this review article basically concentrates on structure of pulp, classification of diseases related to pulp and periradicular tissue and detailed explanation of diseases

O isolamento social durante a pandemia do Sars-Cov-2 aumenta ou diminui a poluição sonora no ambiente urbano?
Authors: De Matos Abe Guilherme , Reis Santos Laís , Vieira Teles Filho Ricardo
Published: October 2020

A disseminação pandêmica do Sars-CoV-2 por mais de 100 países em todo mundo fez com que diversos governos decretassem medidas de restrição de mobilidade social conhecidas como “isolamento social”. Esse cenário pode ter, como efeito colateral, uma percepção de redução da poluição sonora, que pode ser corroborada pela mensuração do impacto sonoro em ambientes públicos nas cidades submetidas às medidas de isolamento social. Entretanto, há registros de aumentos de queixas às autoridades por poluição sonora advindos de zonas residenciais, o que pode indicar, contrariamente, seu aumento. Considerar essas facetas duais do assunto é importante para qualquer estudo que deseje aprofundar as análises. A poluição sonora e seus efeitos danosos sobre a saúde são de grande relevância no cenário pandêmico atual, pois podem se somar a vários outros estressores que conjuntamente ameaçam a saúde mental de populações nesse cenário. Este trabalho, a partir de publicações científicas e de imprensa feitos durante o período, analisa e coloca em discussão as diferentes facetas dessa conjuntura que podem influenciar na elaboração de políticas públicas em saúde.
Spatial sedimentation characteristics in shallow trapezoidal reservoirs
Authors: Dutta Subhasri , Harshvardhan  , Sen Dhrubajyoti
Published: October 2020

In this study, a related and hitherto largely unexplored and unreported area of sedimentation in trapezoidal reservoirs is investigated, with the aid of a coupled numerical hydrodynamic and sediment transport simulation model. This research study is categorised into the following steps: identifying significant geometric parameters defining any typical storage reservoir, setting up and running a numerical model for simulating flow and sediment movement for a range of possible geometries, expressing characteristic parameters defining the extent of sedimentation (height of sediment mound, spatial spread and longitudinal extent) in terms of the geometric parameters, validating relations so obtained with field observations of sedimentation from the Hirakud Reservoir (Eastern India) within its two contributing rivers — Mahanadi and Ib. The study shows that the reservoir geometry and bathymetry significantly influence the flow field which, in turn, dictates the conditions of sediment transport and deposition within the reservoir. The developed relations are expected to help the reservoir managers in understanding the nature of bed elevation rise with time for a given reservoir and for planning desiltation strategies for conserving reservoir capacity.
Using a safety management system to reduce errors and violations
Authors: Mollo Lesiba George , Emuze Fidelis , Smallwood John
Published: October 2020

This study discusses if and how a safety management system (SMS) mitigates or reduces errors and violations on construction sites. The study investigated SMS systems on three major projects in South Africa. The results affirmed that SMS helps to control hazards and risks, but the desired outcome could only be achieved if it is designed and implemented appropriately. The results suggested that on the construction sites visited, inadequate implementation ultimately resulted in errors and violations becoming the norm. The apparently poor implementation observed during the study was cause for concern. It should be addressed, jointly, by both workers and management.

To design a steel shear wall, dynamics of stress concentration on the columns and beam under lateral loads is essential. Therefore, it has been suggested that the thickness of plates should be reduced as much as possible. In cases where a plate with low thickness is not available, this is compensated by using either low-yield-stress plate or by preparing some holes in the structure. Two objectives are pursued in this study, namely, the formulation of a new time integration method for evaluating structural seismic behaviour, and to discover the influences of the yield strength of the steel plate and openings on the wall. The results obtained indicate that the proposed scheme can accurately assess the seismic performance of structures. In addition, in the shear wall with low yield stress, where the steel plate has 5% and 10% openings, there are no significant differences between the outputs of widespread and concentrated openings. The behaviours of these two kinds of shear walls are approximately the same.

To resolve the problem of ductile fracturing of beam flanges in traditional connections with concrete-filled steel tube columns using site-welded side plates, an alternative connection design requiring minimal site welding was designed and studied. An explicit analysis method, considering the fracture strain criterion developed by the stress triaxiality path, was adopted to study the seismic performance and fracture resistance of the proposed connection. The results of a verified finite-element model indicated that the steel beam flange in the connection never fractured. The connection exhibited a notably higher maximum bending moment and ductility than the traditional connection. The side plates in the proposed connection were tension-bending or compression-bending elements, unlike in the traditional connection. The failure modes, maximum bending moment, ductility and stress distribution of the side plates were compared and analysed parametrically. Based on the stress distribution of the side plates according to the finite-element results, a fitting formula related to the width and thickness of the side plates was obtained. A formula to calculate the flexural capacity was also developed according to the force model of the proposed connection. The calculations and finite-element results were in good agreement.
The clue is the mix. Multifunctional re-uses in former retail real estate properties
Authors: Hangebruch Nina
Published: October 2020

In view of the increasing sales dynamics in online retail, city centres and retail properties are currently undergoing profound changes in their use. Stationary retail is reducing its demand for space, department stores are closing, shopping centres are losing their tenants – the functions within the city centres are being re-mixed. The retraction of retail stores from city centres offers the opportunity for other uses: living, offices, leisure and culture or hotels. Over the last 25 years, Germany has had extensive experience regarding the conversion of former department store properties. The buildings are being less frequently re-used as pure shopping destinations. Instead, hybrid, multifunctional re-uses are increasing, especially since 2015. Redevelopment for new uses is time-consuming and technically complex, but generally feasible in the existing buildings. It extends the period of use of the properties through sustainable re-use. The experience gained from the redevelopment of abandoned department stores in Germany can be of value to other countries that are confronted with department store closures (United Kingdom, Netherlands) and can even be used for the redevelopment of shopping malls.

Despite advancements in the neurophysiology of language and presurgical evaluation for epilepsy surgery, there is a paucity of information in the literature regarding presurgical evaluation of multilingual patients. We present a case of a 52‐year‐old right‐handed woman with refractory epilepsy who was fluent in six languages and underwent subsequent trilingual presurgical evaluation which included neuropsychological testing, Wada testing, functional magnetic resonance imaging (fMRI), and electrocortical stimulation. These studies suggested a seizure focus in the left temporal lobe and language localization that was predominantly right‐hemispheric; she subsequently underwent left temporal laser interstitial thermal therapy without clinical disturbance in language function while remaining seizure‐free. A multidisciplinary effort was integral in providing an optimal outcome for this patient.

We report the atypical presentation of Lafora disease in a Senegalese girl carrying the homozygous variant, c.560A>C, in the NHLRC1 gene. At 13 years, the patient developed myoclonic and visual seizures, progressive psychomotor slowing, and cognitive decline. At 14 years, a neurological examination showed severe hypomimia, bradykinesia, rigidity and low‐amplitude myoclonic jerks. Flash‐visual and somatosensory evoked potentials showed an increased amplitude of the cortical components, while an electroretinogram showed attenuated responses. An EEG showed diffuse polyspikes associated with positive‐negative jerks as well as posterior slow waves and irregular spikes. The electroclinical picture suggested the diagnosis of Lafora disease regarding the association of visual seizures, cognitive deterioration, and action myoclonus, together with the EEG and evoked potential findings. Two uncommon findings were the prominence of extrapyramidal signs in the early stage of disease (which are rarely reported) and attenuation of electroretinal responses. We consider that Lafora disease should be included in the diagnostic work‐up for juvenile Parkinsonism, when associated with epilepsy.

Aim: The purpose of this study was to compare HMGB‐1, TLR4, IL‐1β, IL‐1R1, and TNF‐α levels in patients with mild and severe epilepsy with those in a healthy control group.

Methods: Children aged 4–17 years, diagnosed with epilepsy for at least three years and with no progressive neurological disease, metabolic disease or infection, were selected for the study. The severe epilepsy group consisted of 28 children with at least one episode a week despite receiving three or more antiepileptic drugs. The mild epilepsy group consisted of 29 children with no seizures in the previous year, receiving only one antiepileptic drug, while 27 healthy children were selected as the control group. HMGB‐1, TLR4, IL‐1R1, TNF‐α and IL‐1β levels were investigated in these three groups. The MRI findings and clinical characteristics of the patients in the epilepsy group were also compared with these markers.

Results: HMGB‐1, TLR4, TNF‐α, and IL‐1β levels in the severe epilepsy group were higher than in the control group and the mild epilepsy group (p<0.05), and were higher in the mild epilepsy group than in the control group (p<0.05). IL‐1R1 was also higher in the severe epilepsy group than in the control group (p<0.05).

Conclusion: In this first report to identity a possible correlation between HMGB‐1, TLR4, IL‐1β, IL‐1R1, and TNF‐α levels and severity of epilepsy, our data demonstrates that the serum level of these cytokines is higher in cases of drug‐refractory epilepsy.

Based on the oral chronic toxicity studies in humans, the daily intake of Lupinus albus L. (termiye, white lupine) with diet is recommended to be about 0.02%. The study was designed to investigate the use of lupine shells in nutrition. Dried L. albus shell was added to the artificial diet of the model organism (Drosophila melanogaster) and then lipid peroxidation, antioxidant enzyme activity, total oxidation, and total antioxidant activity were determined in the tissues obtained from the third larval phase. Changes that occurred in the larval midgut cells were examined microscopically. As the amount of shell consumption increased, malondialdehyde concentration (0.33 - 0.09 ± 0.71 nmol/ mg protein) and glutathione S transferase activity (19.91 - 14.06 ± 0.04 nmol/ mg protein/ dk) decreased statistically compared to the control. In addition to this, larval total oxidation level and total antioxidant activity also decreased (P < 0.05). No damage was detected in the larval midgut epithelial cells.

Aim: The aim of this study is to investigate whether neuregulin-1 gene (NRG1) rs6994992 polymorphism has any role in gifted students in Turkish population.
Methods: During the 2017-2018 academic year, 97 gifted students (experiment group) and 99 students with normal development (control group) attending 5th grade of different public schools participated in the research. Genomic DNA was extracted from the oral epithelial cells. Genotyping of the molecular variant was performed by Polymerase Chain Reaction- Agarose gel electrophoresis-DNA sequencing techniques.
Results: Genotype difference in gifted students was estimated as odds ratio and 95% confidence interval using binary logistic regression models. While the frequencies of CC (wild type), CT (heterozygous), TT (polymorphic type) genotypes were 33.0, 53.6 and 13.4%for the experimental group, respectively, they were observed as 33.0, 60.0 and 7.0% in the control group. In the Turkish population, no association could be detected for both genotype and allele distribution for NRG1 rs6994992 C/T polymorphism between gifted and control group (OR: 0.538, CI: 0.190-1.525, p = 0.244).
Conclusion: According to the results of our study, there was no relationship between NRG1 rs6994992 polymorphism and gifted students in the Turkish population.
