Bi-directional movement characteristics of Camponotus japonicus ants during nest relocation
Authors: Wang Qiao , Song Weiguo , Zhang Jun , Lo Siuming
Published: July 2018

Foraging and nest relocation forming a bi-directional traffic of outbound and inbound individuals in one-lane organization are two main activities in ants’ life. In this paper, we conducted an experiment for nest relocation of loaded and unloaded ants, and some of them move back and forth between the old nest and the new one. In the experiment, we observed both uni- and bi-directional traffic flows of ants. The headway-speed relations indicate that the ants show the same sensitivity to the distance headway in both types of flows. For bi-directional traffic flow, head-on encounters and giving way behavior between opposite ants are common occurrence. It takes one unloaded ant 2.61 s to solve a head-on encounter with other unloaded one. Compared with unloaded ants, loaded ants have smaller moving speed, but are less likely to be impacted by head-on encounter. In observation region, both sudden stop and head-on encounter contained two phases, i.e. deceleration and acceleration were observed. Our analysis indicates that the relaxation time in deceleration process is less than that in acceleration process. The reduction of movement efficiency of encountering two discontinuous ants is larger than encountering two successive ants 0.18. This is owing to the absence of head-on encounter with following ants. Generally, this study investigates the bi-directional traffic of ants in experimental condition mainly and might inform the future studies of high-efficiency movement of collective behavior and traffic systems.
BED: a Biological Entity Dictionary based on a graph data model
Authors: Godard Patrice , van Eyll Jonathan
Published: July 2018

The understanding of molecular processes involved in a specific biological system can be significantly improved by combining and comparing different data sets and knowledge resources. However, these information sources often use different identification systems and an identifier conversion step is required before any integration effort. Mapping between identifiers is often provided by the reference information resources and several tools have been implemented to simplify their use. However, most of these tools do not combine the information provided by individual resources to increase the completeness of the mapping process. Also, deprecated identifiers from former versions of databases are not taken into account. Finally, finding automatically the most relevant path to map identifiers from one scope to the other is often not trivial. The Biological Entity Dictionary (BED) addresses these three challenges by relying on a graph data model describing possible relationships between entities and their identifiers. This model has been implemented using Neo4j and an R package provides functions to query the graph but also to create and feed a custom instance of the database. This design combined with a local installation of the graph database and a cache system make BED very efficient to convert large lists of identifiers.

В статье приводятся результаты изучения влияния современных регуляторов роста растений (Домоцвет, Эпин-экстра, Циркон, Рибав-экстра, Экогель) на всхожесть семян и морфометрические параметры декоративных культур на примере представителей рода Ligularia Cass. Исследования проводили в 2016-2017 годах на базе Южно-Уральского ботанического сада-института – обособленного структурного подразделения Федерального государственного бюджетного научного учреждения Уфимского федерального исследовательского центра РАН. Объектами исследования стали семена трех видов рода Ligularia (L. dentata, L. fischeri, L. przewalskii). Предпосевную обработку семян проводили путем их замачивания в растворах регуляторов роста при комнатной температуре по следующей схеме: Домоцвет, норма расхода – 1 мл на 10 л воды, замачивание семян на 4 часа; Эпин-экстра, норма расхода – 1 мл на 2 л воды, замачивание семян на 4 часа; Циркон, норма расхода – 1 мл на 4 л воды, замачивание семян на 4 часа; Рибав-экстра, норма расхода – 1 мл на 10 л воды, замачивание семян на 2 часа; Экогель, норма расхода – 20 мл на 1 л воды, замачивание семян на 6 часов; контроль (вода), замачивание семян на 4 часа. Показано, что самыми результативными на всхожесть семян оказались препараты Домоцвет и Рибав-экстра, они повысили всхожесть у всех изученных видов в 1,1–1,8 раза. На биоморфологические показатели наиболее эффективными оказались препараты Домоцвет, Эпин-экстра и Рибав-экстра. Они увеличили высоту растений в 1,1–1,7 раза; длину главного корня в 1,2 раза; количество корней в 1,1–2,2 раза; длину и ширину листа в 1,2–1,6 и 1,2–2,1 раза соответственно. Таким образом, отмечено положительное влияние регуляторов роста растений на всхожесть семян и биоморфологические показатели некоторых представителей рода Ligularia.

Цель исследования: Представить читателю подробный исторический обзор о применении пряных и ароматических растений в психиатрии и неврологии, а также данные современных исследований об их эффективности в терапии различных психических и психосоматических патологий, нейродегенеративных заболеваний.Методология проведения работы: В качестве начальной отправной точки для нашей работы мы взяли список всех применяемых в кулинарии различных народов специй и приправ из английской Википедии, как один из наиболее полных подобных списков в Интернете (en.wikipedia.org/wiki/List_of_spices). Затем мы изучили современную доказательную базу и исторические данные о применении каждого из упомянутых в данном списке растений, используя поисковые системы PubMed, Google Scholar, Science Direct, Web of Science, и представили найденные данные в настоящем обзоре.Результаты: Полученные нами в результате составления настоящего обзора данные свидетельствуют о значительном терапевтическом потенциале многих пряных и ароматических растений в психиатрии и неврологии, в особенности в лечении лёгких форм тревожных и депрессивных расстройств, лёгких когнитивных нарушений, а также в лечении таких психосоматических заболеваний, как синдром раздражённого кишечника, мигрень, синдром предменструального напряжения, климактерические расстройства. Доказательная база для применения в психиатрии и неврологии разных пряных и ароматических растений различна по качеству. Для одних пряных и ароматических растений и извлечённых из них биологически активных веществ пока существуют лишь данные экспериментов на животных в сочетании с эмпирическим опытом народной медицины, для других – имеются предварительные обнадёживающие результаты открытых пилотных исследований на человеке, для третьих, таких, как куркумин, сафранал – положительные результаты небольших рандомизированных клинических испытаний. Важно, однако, то, что исследование психотропного и нейротропного потенциала пряных и ароматических растений, судя по количеству публикаций именно в последние годы (2013–2017), рассматривается как одно из перспективных направлений для поиска новых антидепрессантов, анксиолитиков и антидементных препаратов.Область применения результатов: Полученные нами результаты дают теоретические и практические основания для применения экстрактов из некоторых пряных и ароматических растений, таких, как куркумин, сафранал, пиперин, эфирное масло лаванды, в лечении лёгких форм тревожных и депрессивных состояний, лёгких когнитивных нарушений, особенно у пациентов, отказывающихся от фармакотерапии или плохо её переносящих.

Creating and implementing local health and wellbeing policy: networks, interactions and collective knowledge creation amongst public sector managers
Authors: Ward Vicky , Smith Simon , Keen Justin , West Robert , House Allan
Published: July 2018

Background

In the UK managers from multiple organisations are commonly tasked with collectively devising and implementing local health and wellbeing policies as a way of addressing increasing demand for healthcare. This requires them to create knowledge together but relatively little is known about how this occurs. This paper reports the results of research into how managers collectively create knowledge in order to address local health and wellbeing challenges.

Methods

We undertook a case study in three sites in England. Using statistical network modelling we identified clusters of actors and interviewed managers from heterogeneous clusters about their collective activities. We used interview and documentary data to construct accounts of collective knowledge creation.

Findings

Managers simultaneously work across stable bureaucratic networks and temporary taskforces in order to create and implement local health and wellbeing policy. They collectively create knowledge by enacting networks of relationships which enable them to share and build on routines and discourses and to reach out for new evidence, perspectives and skills. When creating knowledge, managers’ ability to draw on and harmonise alternative programmes of action and their willingness to collectively negotiate is more important than their managerial status or position.

Conclusions

Managers should be encouraged to examine and discuss their alternative programmes of action and to see these as a catalyst for rather than barrier to collectively creating and implementing local health and wellbeing policies, and should be supported and valued for their ability to harmonise conflicting programmes of action.

Published: July 2018

Quercus humboldtii es un elemento dominante en los bosques altoandinos de Boyacá, Colombia, el cual, a pesar de ser una especie sombrilla, registra consumos per-cápita de 1300 Kg.año-1 y el remplazo de sus rodales por plantaciones de Pinus patula. Este remplazo afecta las comunidades liquénicas más sensibles. Para rastrear dichas afecciones se examinaron los líquenes en cuatro árboles de cada especie forófita. Cada árbol fue dividido en cinco estratos verticales y se midió la rugosidad, humedad, acidez y luminosidad en cada estrato. Los análisis comprendieron índices de diversidad, tablas Anova y escalas multidimensionales. Se registraron 161 especies de líquenes, se reconocen 53 especies exclusivas sobre pino y 45 exclusivas de roble. Se destacan Cladonia ceratophylla y Herpothallon rubrocinctum como especies comunes entre forófitas, y la exclusividad de Astrothelium spp, Anzia leucobatoides y Leptogium diaphanum sobre los robles. La luminosidad y la rugosidad son factores de influencia en la distribución de los líquenes.

Upstream Gajahwong Sub-Watershed included in Yogyakarta Urban Agglomeration Region and regional development of tourism that utilizes the beauty of the slopes of Mount Merapi also the support accessibility (Solo-Magelang-Semarang road; this condition is assumed to be the cause of landuse changes, followed by vegetation land shrinkage. The shrinkage’s result is water catchment areas reduction that disrupts the Sub-Watershed hydrology function. One of indication is the increasing flood discharge that can be seen from the changes in surface runoff and peak flow rate. This research aims to assess the impact of landuse change on surface runoff and peak flow rate in Gajahwong Sub-Watershed using a quantitative method that consists of spatial and mathematic analysis with SCS and Rational Method. The results showed that the landuse changes impact on increasing surface runoff and peak flow rate. The surface runoff in year 2002 amounted to 3.073 mm with a peak flow rate of 98.02 m³/sec then increased to 3.901 mm with a peak flow rate of 101.65 m³/sec in year 2011. The landuse changes that occur tend to built landuse which was followed by vegetation shrinkage and impact on the increase in surface runoff and peak flow rate. Predictions in year 2031 also showed an increase in surface runoff and peak flow rate, if there is a tendency of landuse changes linearly as landuse changes in year 2002 – 2011. Alternative analytical efforts to handle surface runoff and peak flow rate showed that by combining the development of Green Open Space with water conservation technology (Biopori and Infiltration Wells) can reduce surface runoff and peak flow rate.

The spatial pattern of Semarang illustrate how the pattern that separates the production zone  with consumption zone. Consumption zone is where we live, while the production zone is where we work, shop, school prayer, and recreation. The condition causes the townspeople have to commute (nglajo) every day from the residence to the production zone. Patterns of community life of the city brought in a mechanical rhythm of having to use a motor vehicle. Be they as a community-based automobile (Hadi, 2001: 100-101). The existence of these problems lead to the birth of the Self-reliant  New Town BSB Semarang. Bukit Semarang Baru (BSB) as an Self-reliant  New Town is an integrated spatial planning, where the provision of shelter is equipped with facilities meeting the needs which are within the scope of one area or also called mixed use zoning. To examine changes in activity and mobility of people in urban space integrated pattern which in this case is the Self-reliant New Town BSB then used a socio-ecological systems approach. Socio-ecological systems see the extent of the interaction between different systems. The link between humans and the environment is realized through a variety of physiological processes, psychological and cultural (Lawrence, 2003). The method used in this study is a mix methods with quantitative and qualitative approaches. A quantitative approach is used to analyze the activity and mobility patterns, and a qualitative approach to explain the socio-ecological system of the community. Results from this study that of the five regular activity performed, shopping activities and religious activities have high interaction, because most people have been doing the activity in the region, while for other activities such as the activity of work, school and activity in leisure time is still done in BSB outside the region. The use of public transport modes BSB still choose a long private vehicle.

The consequences of population growth is the increasing housing needs of the community. Labor is part of the low and middle-income people should get the attention of government and developers to meet the housing needs. Problems of housing and settlements can not be regarded as a functional and purely physical problems, but more complex as the problems related to the dimensions of social life that includes social, economic, cultural, ecological, technological and political. Provision of occupancy against labor by governments or developers should consider the desire and tendency to settle labor based on its characteristics as a prospective occupant so as to create housing that is accommodative to the occupants. Preferences settled labor of Makassar Industrial Estate is divided into four categories, which are not thinking of moving their homes, thinking of moving residential, residential moving plan and is ready to move occupancy. Based on the study of labor industrial area of Makassar, obtained results indicate that there are 59% of the workforce did not think to move dwelling occupied at the moment. 32% of its workforce started thinking to relocate occupancy but do not know the right time to move on, 7% of its workforce is planning to move the occupancy by a predetermined time and 2% of the workforce that is ready to move current occupancy. Socio-economic characteristics, housing and residential environment that significantly affect labor preference settled industrial area of Makassar is marital status, type of occupancy, status of ownership and residential neighborhood tranquility.

Inspired by the study of control scenarios in elections and complementing manipulation and bribery settings in cooperative games with transferable utility, we introduce the notion of structural control in weighted voting games. We model two types of influence, adding players to and deleting players from a game, with goals such as increasing a given player’s Shapley–Shubik or probabilistic Penrose–Banzhaf index in relation to the original game. We study the computational complexity of the problems of whether such structural changes can achieve the desired effect.
Interleukin IL-1α, IL-6, IL-8, IL-10 Expression in Different Staging of Cervical Intraepithelial Neoplasia
Authors: Balode Evija , Pilmane Mara , Rezeberga Dace , Jermakova Irina , Kroica Juta
Published: July 2018

Introduction. Cervical cancer is the fourth most common form of cancer in women [19]. The precancerous stages are divided into three distinctive stages, labelled cervical intraepithelial neoplasia (CIN) I, II and III. One of the aetiological factors is chronic inflammation in cervical tissue, most often induced by Human papilloma virus (HPV). 88,5% of the patients regress from low grade intraepithelial changes to unchanged epithelium [14]. It has been proposed that cytokine balance plays a key role in the development of high grade epithelial changes (CIN I – CIN III) in the remaining 11.5% of patients, however, the exact trigger of this event remains to be found.

Aim of the Study. The aim of the study was to determine three pro-inflammatory (IL-1α, IL-6, IL-8) and one anti-inflammatory (IL-10) interleukin expression in different CIN cervix uteri biopsies.

Material and methods. 16 biopsies were obtained with different CIN staging: one with CIN I stage, five with CIN II stage and 10 with CIN III stage. The samples were stained with haematoxylin and eosin and immunohistochemistry for IL-1α, IL-6, IL-8 and IL-10. Slides were evaluated semi-quantitatively grading the intensity of positively stained structures in the visual field.

Results. Examination of the samples yielded the following: IL-1α expression increased from CIN II to CIN III in squamous epithelium, while IL-8 expression decreased. A few IL-1α containing inflammatory cells were found in all CIN stages. IL-8 expression in subepithelium and the number of inflammatory cells decreased from CIN II stage to CIN III, although, it increased in the blood vessel endothelium.

Conclusions. There was constant moderate expression of both IL-6 and IL-10 during all CIN stages, except for inflammatory cells, where IL-6 expression was high during all stages, yet there were few IL-10 containing cells during CIN. The balanced expression of both cytokines suggests that pro- and anti-inflammatory cytokine balance has an important role in CIN morfopathogenesis. The high expression of IL-6 in inflammatory cells and constant expression trough CIN staging indicates sustentation of chronic inflammation and production of other cytokines, such as IL-8, IL-1α. The variable IL-8 expression and its decrease in CIN III stage suggests the depletion of IL-8 production. The high expression of cytokines in blood vessel endothelium indicates their important role in CIN morfopathogenesis.
Critical media literacy through making media: A key to participation for young migrants?
Authors: Leurs Koen , Omerović Ena , Bruinenberg Hemmo , Sprenger Sanne
Published: July 2018

Young migrants – particularly refugees – are commonly the object of stereotypical visual media representations and often have no choice but to position themselves in response to them. This article explores whether making young migrants aware of the politics of representation through media literacy education contributes to strengthening their participation and resilience. We reflect on a media literacy program developed with teachers and 100 students at a Dutch “International Transition Classes” school. The educational program focuses on visual media production using smartphones, raising critical consciousness and promoting civic engagement. Ethnographic data analyzed include field notes, a focus group with teachers, in-depth and informal interviews, student-produced footage, and a 10-minute ethnographic film. In our increasingly polarized mediatized world, better recognition of how the needs of certain young people diverge depending on how they are situated in racialized, gendered, and classed structures of power is needed to work towards inclusive media literacy education.

Osteoid osteoma is a rare occurrence in the hand, especially in children. We report here a rare case of a 12-year-old boy complaining of growing painful swelling of the middle phalanx of the third finger that had started 3 months earlier and had not responded to anti-inflammatory medication. Based on the clinical findings and plain radiographs, osteomyelitis or Ewing’s sarcoma was suspected. However, MRI revealed the typical characteristics of osteoid osteoma. The lesion was excised, and the histological examination confirmed the diagnosis. We make a brief review of the literature concerning this uncommon localization and discuss the differential diagnosis and treatment modalities.

Authors: Shindova Maria P. , Belcheva Ani B. , Mateva Nonka G.
Published: July 2018

Background: Acceptance of lasers as alternatives and accessory tools to traditional methods in dental medicine has created an explosion of interest. Er:YAG laser is recommended for enamel conditioning. There is no study evaluating the anxiety in children during fissure sealing procedures when using Er:YAG laser compared to the routine application technique.

Aim: To evaluate the objective and subjective stress parameters in children during a preventive procedure when using Er:YAG laser for additional enamel conditioning before pit and fissure sealant application compared to the routine clinical application technique.

Materials and methods: The study included sixty-four 6-12-year-old children, divided into two equal treatment groups. A standardized fissure sealant application was performed, as in the intervention group before acid etching, the occlusal surfaces of teeth were conditioned with Er:YAG laser (2940 nm). During the procedure, objective and subjective stress parameters were recorded.

Results: Significantly lower degree of dental anxiety was found at the end of the dental visit of the study group (p<0.001). During the professional cleaning of the tooth surface, the mean heart rate was low (95.55±14.29 bpm) within the physiological normal range. The objective and subjective stress parameters show no significant differences between the two subgroups during sealing procedure (p>0.05).

Conclusions: Application of Er:YAG laser during sealant application does not provoke anxiety and is well accepted by children in dental environment. Preventive procedures at the beginning of a dental visit decrease the initial levels of dental anxiety and contribute to an effective treatment process.

Published: July 2018

Aim: Epidemiological study of the incidence of mechanical low back pain (LBP) in non-professional female Greek classic ballet dancers over a year and therapeutic interventions required to address symptoms.

Materials and methods: Forty-six female classic ballet dancers members of preprofessional schools, aged 16-37 years (mean 28.8 ±5.44 yrs) practicing and training in classic dance for 6-40 hours/week (mean 10.8±6.68) and 2-27 years experience (mean 11.9±4.20 yrs) participated in an epidemiological study concerning the incidence of LBP episodes within the last year, the treatment they received, as well as the period of absence of training and performance due to LBP. A selfadministered questionnaire was employed. Information regarding incidence, duration, and intensity of mechanical low back pain was gathered as well as length of time away from practice or performance. A secondary aim was to investigate the type of conservative treatment that participants in this study received.

Results: Thirty-one (67.4%) participants in the study experienced 1-10 (mean 3.26±1.7) episodes of mechanical LBP in the previous 12 months. They had to refrain from dancing activities from 2 to 90 days (mean 16.9±16.22). Twenty one of the participants received some kind of conservative treatment.

Conclusion: The incidence of LBP was found to be high among Greek amateur classic ballet dancers resulting in absence from dancing activities for a considerable length of time and raising the need for therapeutic intervention for a considerable percentage of the studied population. Effective prevention strategies of LBP are of vital importance, particularly in younger dancers.

The changes in cognitive functions that occur with aging and in various pathological conditions are a subject of growing interest. Experimental and clinical data justify the hypothesis about the influence the immune system exerts on cognitive processes. The balance between pro-inflammatory and anti-inflammatory cytokines has been established as a necessary factor for normal cognitive functioning. Cytokine production is under strong genetic control and various single nucleotide polymorphisms (SNPs) in cytokine genes have been described. As cytokine SNPs have been demonstrated to affect the gene expression or the functional activity of the immune protein this logically led to the suggestion about the role of these polymorphisms in cognitive functioning. Studies exploring the association between different genetic variants of cytokine gene polymorphisms and cognitive abilities in healthy subjects and in demented patients show divergent results. The review of relevant literature suggests that SNPs implement their effect on cognition in large interactions with each other, as well as with many other factors, some of which still remain to be identified. This article summarizes the contemporary knowledge about the correlations between SNPs in cytokine genes and cognitive status in humans. Further research is needed to determine the precise role and the molecular mechanisms of action of the SNPs in cognitive processes.

The study on the behaviour of decarburization, temperature increase, change of phosphorus and oxygen content of liquid steel during reblow process was presented in this paper. On the basis of traditional three-stage decarburization theory and thermal equilibrium theory, models for the variation of carbon content and temperature were established. Moreover, with application of data mining method, models for change of phosphorus and oxygen content were built based on large amount of production data and thermodynamic theory. By considering the variation of composition and temperature of molten steel, the reblow model was obtained and the software for reblow operation was developed with the combination of production technology. The test results indicated that the reblow rate (reblow more than once) dropped from 3.99 % to 0, and the average tap to tap time was reduced from 37.43 min to 36.35 min. It could provide an effective solution for medium-high carbon steel melting.

Biomass is an attractive target in process development for the emerging renewable resources based bio-refinery industry. Due to the ample range of application of acrylic acid, its production through bio-route received more awareness in scientific fraternity. In this view, an attempted was made to study the reactive extraction of acrylic acid with aliquat 336 in rice bran oil. Moreover, Box-Behnken matrix was employed to corroborate the effects of process variables viz. concentration of acrylic acid [CAA]aq, concentration of aliquat 336 [CR4N
+
Cl], and temperature on the extraction efficiency (η%). In physical extraction, average extraction efficiency was found in the order as: 43.55 > 35.36 > 29.14 at 303 K, 323 K, and 343 K respectively in rice bran oil. The correlation coefficient, R2 = 0.988 % indicates the appropriateness of proposed model to predict the extraction efficiency in terms of independent variables, and the predicted values were found in close agreement with that of experimental results. Further, R2
(Pred) = 0.806 is in reasonable agreement with the R2
(Adj) = 0.972. The optimum conditions for extraction of acrylic acid using aliquat 336 as an extractant in rice bran oil are [CAA]aq = 0.0.5 (mol/kg); [CR4N
+
Cl] = 1.98 (mol/kg); temperature = 323 K and the model predicted extraction efficiency 77.5 % was found to be an excellent fit with the experimental value 75 %. Further, number of theoretical stages was found to be 3 and S/F ratio 0.247.

In this paper we study a class of semilinear evolution equations with nonlocal initial conditions and give some new results on the existence of asymptotically periodic mild solutions. As one would expect, the results presented here would generalize and improve some results in this area.
Curves in the Lorentz-Minkowski plane: elasticae, catenaries and grim-reapers
Authors: Castro Ildefonso , Castro-Infantes Ildefonso , Castro-Infantes Jesús
Published: July 2018

This article is motivated by a problem posed by David A. Singer in 1999 and by the classical Euler elastic curves. We study spacelike and timelike curves in the Lorentz-Minkowski plane 𝕃2 whose curvature is expressed in terms of the Lorentzian pseudodistance to fixed geodesics. In this way, we get a complete description of all the elastic curves in 𝕃2 and provide the Lorentzian versions of catenaries and grim-reaper curves. We show several uniqueness results for them in terms of their geometric linear momentum. In addition, we are able to get arc-length parametrizations of all the aforementioned curves and they are depicted graphically.

Baicalein inhibits neuroapoptosis via pathways in sevoflurane induced rats
Authors: Wang Si , Zhou Yu
Published: July 2018

Background

Baicalein, a bioactive flavonoid was explored for its capability to attenuate sevoflurane induced neuronal apoptosis and to improve behavioural and cognitive impairments. Sevoflurane is a frequently used inhalation anesthetic in neonates and children. Neonatal sevoflurane exposure causes widespread neurodegeneration and cognitive impairments. Development of compounds that could effectively prevent/reduce the adverse effects is of tremendous medical value.

Methods

Isolated groups of neonatal rats were regulated with baicalein (25, 50 or 100 mg/kg b.wt) from postnatal day 3 (P3) to P21 and were exposed to sevoflurane (3%; 6 h) on P7. Results: Baicalein inhibited sevoflurane induced neuroapoptosis significantly as assessed by TUNEL assay. The raised levels of cleaved caspase-3, Bad and Bax were down-regulated by baicalein with enhanced Bcl-2, Bcl-xL, xIAP, c-IAP-1, c-IAP-2 and survivin expression. Baicalein regulated JNK/ERK signalling and also activated the PI3K/Akt pathway effectively as evident from the increased Akt, phospho-Akt, GSK-3β, phospho-GSK-3β levels. Baicalein, also improved the behaviour of animals in open filed and olfactory tests. The freezing responses and the performance in Morris Water Maze tests were enhanced.

Conclusion

Baicalein reduced neurodegeneration and improved learning and memory retention of rats and as well modulated PI3/Akt/GSK-3β and JNK/ERK signalling pathways.
The Insulator Protein CTCF Is Required for Correct Hox Gene Expression, but Not for Embryonic Development in Drosophila
Authors: Gambetta Maria Cristina , Furlong Eileen E M
Published: July 2018

Insulator binding proteins (IBPs) play an important role in regulating gene expression by binding to specific DNA sites to facilitate appropriate gene regulation. There are several IBPs in Drosophila, each defined by their ability to insulate target gene promoters in transgenic assays from the activating or silencing effects of neighboring regulatory elements. Of these, only CCCTC-binding factor (CTCF) has an obvious ortholog in mammals. CTCF is essential for mammalian cell viability and is an important regulator of genome architecture. In flies, CTCF is both maternally deposited and zygotically expressed. Flies lacking zygotic CTCF die as young adults with homeotic defects, suggesting that specific Hox genes are misexpressed in inappropriate body segments. The lack of any major embryonic defects was assumed to be due to the maternal supply of CTCF protein, as maternally contributed factors are often sufficient to progress through much of embryogenesis. Here, we definitively determined the requirement of CTCF for developmental progression in Drosophila. We generated animals that completely lack both maternal and zygotic CTCF and found that, contrary to expectation, these mutants progress through embryogenesis and larval life. They develop to pharate adults, which fail to eclose from their pupal case. These mutants show exacerbated homeotic defects compared to zygotic mutants, misexpressing the Hox gene Abdominal-B outside of its normal expression domain early in development. Our results indicate that loss of Drosophila CTCF is not accompanied by widespread effects on gene expression, which may be due to redundant functions with other IBPs. Rather, CTCF is required for correct Hox gene expression patterns and for the viability of adult Drosophila.
Investigating the Relationship between Classroom Conversation and Argumentative Writing Using Writing Moves and Types of Talk
Authors: Brady John
Published: July 2018

[full article in English]

In this paper, I investigate the relationships between classroom talk and dialogic literary argumentative writing. My work is situated within a larger body of recent research on argumentative writing, taking up a social practice understanding of argumentative writing as being a set of social practices that are situated within a larger process of learning over time (Newell, Bloome & Hirvela 2015). This perspective aligns with the current understandings of writing that have been taken up over the past fifteen years (Nystrand, Green & Weimelt 1993; Klein & Boscolo 2016; Newell, Beach, Smith & VanDerHeide 2011).I adopt a Bakhtinian frame to investigate classroom argumentative writing and talk, which entails a negotiation between the meaning of events and utterances through interaction. Because of this, all interactions and utterances are inherently dialogic, as they are connected to histories and in anticipation of the future. This perspective frames the teaching and learning of argumentative writing as being negotiated locally over time, with unique practices and ways of knowing established through classroom interaction. This means that the teaching and learning of argumentative practices will always be unique to the contexts in which they are practiced. After establishing this frame, I employ instructional chains and discourse analysis in order to analyze two separate classroom discussions that occurred in two separate classrooms. By doing so, I aim to answer the following questions: what is the relationship between classroom talk and dialogic literary argumentative writing as a social practice? How is talk used to define and develop DLA both in regard to argumentative moves and the concepts and ideas derived from literature?
Wetting under Electromagnetic Resonance Irradiation
Authors: Myhal V. M. , Derzhko O. V.
Published: July 2018

The influence of the resonance electromagnetic irradiation on the wetting of a solid surface by liquid has been discussed. A simple model of a fluid consisting of two-level atoms, for which changes in their interaction due to a resonance irradiation can be found in the framework of the quantum-mechanical perturbation theory is considered, and the corresponding functional for the grand thermodynamic potential is found. The density functional method is used to calculate the surface tension at the liquid–vapor, solid–liquid, and solid–vapor interfaces, and the Young equation is applied to determine the wetting angle. It is shown that the resonance irradiation can significantly increase the latter parameter.
