Authors: Freire Fernanda , Pereira Cristiane Aparecida , Oliveira Luciane Dias , Junqueira Juliana Campos , Jorge Antonio Olavo Cardoso
Published: June 2017

Objective: The aim of this study was to identify the slime production and evaluate the effects of Rosmarinus officinalis (rosemary) and Syzygium cumini (jambolan) glycolic extracts, and 0.12% chlorhexidine (CHX) in biofilms formed by strains of coagulase-positive Staphylococcus - CPS and coagulase negative Staphylococcus - CNS isolated from the oral cavity. Material and Methods: Slime production was evaluated by two methods: the color of colony presented in Congo red agar, and through the amount of slime adhered to polystyrene. Biofilms were grown in acrylic resin discs immersed in broth, inoculated with microbial suspension (106 cells/ml) and incubated at 37°C/48 h. After formation, the biofilms were exposed for 5 minutes to glycol extracts, CHX or saline solution. The viability of biofilms was determined by counting the colony-forming units per milliliter (CFU/ml) in agar, and analyzed statistically by Tukey test (p <0.05). Results: The strains S. aureus, S. schleiferi and S. epidermidis obtained the highest values of slime adhered to polystyrene. R. officinalis promoted reductions ranging from 12.1% to 78.7% in biofilms formed by isolates of CPS, and 9.2% to 73.7% in the biofilms of CNS. S. cumini reduced 12% to 55.7% in biofilms of CPS, and 7.9% to 71.5% in biofilms of CNS. With exception of S. saprophyticus, glycol extracts produced significant reductions in biofilms. For five isolates studied, R. officinalis produced greater reductions than CHX. Conclusion: R. officinalis and S. cumini showed effective antibiofilm activity against isolates that showed slime production. KeywordsBiofilm; Rosmarinus officinalis; Slime; Staphylococcus; Syzygium cumini.

Classroom incidents in which teachers have to exhibit their expertise at managing a class is a commonplace in teachers´ daily routines; though sometimes some of those classroom incidents turn into critical moments. However, ordinary disruptive classroom situations are not as catastrophic as when teachers themselves provoke them. On top of this, when some teachers have to face any sort of classroom disruption, most of them are unable to come up with any immediate and effective solution. In this paper, we will describe how we combined both, the critical incident technique and the cooperative development theory, so as to reflect upon a critical moment of each of us, and be able to improve our viewpoints regarding the potential solutions that can emerge to cope with those critical moments in our own classrooms. The findings show that we strengthened our professional ties, we invigorated our teaching skills and developed from our own insights into new perspectives in relation to how to better tackle classroom management difficulties. Finally, in the conclusions we share how profound were the changes which, by the way, were not only in the pedagogical sense.
CFD modeling and computation of convective heat coefficient transfer of automotive disc brake rotors -Modelado CFD y cálculo de la transferencia de coeficientes de calor por convección de rotores de freno de disco automotores
Authors: Belhocine Ali , Wan-Omar Wan Zaidi
Published: June 2017

Braking system is one of the basic organs to control a car. For many years, the disc brakes have been used in automobiles for safe retardation of the vehicles. During braking, enormous amount of heat will be generated, and for effective braking, sufficient heat dissipation is essential. The specific air flow surrounding the brake rotor depends on the thermal performance of the disc brake and hence, the aerodynamics is an important in the region of brake components. A CFD analysis is carried out on the braking system as the study of this case, to make out the behaviour of air flow distribution around the disc brake components using ANSYS CFX software. The main object of this work is to calculate the heat transfer coefficient (h) of the full and ventilated brake discs as a function of time using the CDF analysis which will be used later in the transient thermal analysis of the disc in ANSYS Workbench 11.0.

Published: June 2017

Contexto: Se realizó una búsqueda local de tejidos de fibras vegetales para determinar la composición de los grupos funcionales y morfología de su superficie antes y después de un tratamiento alcalino con miras a su empleo como refuerzo en compuestos de matriz polimérica.Método: La búsqueda se desarrolló dentro del área metropolitana del Valle de Aburrá, Colombia. Las fibras se trataron por inmersión en NaOH disuelto al 6 % w/v por 48 horas, seguida por una neutralización en ácido acético al 1 % v/v por una hora. Posteriormente fueron secadas a 60 °C por 24 horas. Las técnicas empleadas para los análisis fueron la espectroscopía infrarroja por transformada de Fourier (FTIR) y la microscopía electrónica de barrido (SEM).Resultados: Se seleccionaron tejidos de fique, yute, corteza de coco, lino y algodón. Los análisis FTIR muestran una tendencia a la disminución de ácidos grasos, hemicelulosas, ligninas y enlaces β en la superficie de las fibras, mientras que las imágenes SEM demuestran la remoción de impurezas, la exposición de rugosidades y la creación de espacios interfibrales.Conclusiones: El tratamiento alcalino podría favorecer el mecanismo de anclaje del polímero termofijo a la superficie de las fibras y la creación de enlaces entre las moléculas polares de las fibras y el polímero termofijo, disminuyendo el deslizamiento relativo entre matriz y refuerzo durante la aplicación de cargas.
Consideration on road transport vibration simulation techniques for packaging testing purposes
Authors: Pidl R.
Published: June 2017

Transportation is essential for many logistics systems and vibration is one of the most critic physical circumstances on road causing numerous possible damage sources. One of the primary sources of these damages is often the broadband random vibration. This effect cannot be handled with formal mechanical models; therefore, vibration test simulation is essential for packaging testing. The current vibration systems use Power Spectral Density (PSD) functions to control the intensity of random signal in laboratory based on Fast Fourier Transformation (FFT). Naturally, the PSD frequency does not contain time series data making it hard to determine how long a given simulation should be performed. In this paper, mathematical and probability methods are presented that can be used for representing real vibration circumstances.

Prestes, J, Nascimento, DdC, Neto, IVS, Tibana, RA, Shiguemoto, GE, Perez, SEA, Botero, JP, Schoenfeld, BJ, and Pereira, GB. The effects of muscle strength responsiveness to periodized resistance training on resistin, leptin, and cytokine in elderly postmenopausal women. J Strength Cond Res 32(1): 113–120, 2018—The aim of this study was to evaluate muscle strength responsiveness and to determine whether interleukin 4 (IL-4), leptin, and resistin would be affected by the individual pattern of response to a resistance training (RT) periodization program. Twenty-six elderly postmenopausal women participated in the present study (mean age = 62.57 ± 6.69 years and body mass index = 28.09 ± 4.83 kg·m−2). Four-month longitudinal training program was performed consisting of 2 whole-body sessions per week with increasing intensity and decreasing volume by using 6–14 repetitions maximum (RM). Two acute whole-body RT sessions (before and after chronic training) were also performed comprising 3 sets of 12–14RM. The responsiveness was determined based on their relative muscle strength gains in 45° leg press. High responders were defined as relative muscle strength gains ≥32% and low responders <32% (n = 13 in each group). Muscle strength increased by a higher amount in the high-responsive group as compared with the low-responsive group in the 45° leg press and bench press, whereas muscle strength increased for both groups when compared with pretraining evaluation (p = 0.001). Low responders displayed higher plasma leptin levels when compared with high responders at baseline (p = 0.001), and after 16 weeks of training, leptin levels were significantly lower when compared with baseline (pretraining period). Both groups displayed a decrease in baseline resistin values after 16 weeks of RT, but only a statistically simple main effect was observed for low responders. In addition, there were no effect of time and no significant interaction between the responsiveness and time on IL-4 concentration. In conclusion, RT is effective in improving upper and lower limb muscle strength in elderly women, with higher magnitudes of increase seen for those classified as high responders. Resistin and leptin displayed a decrease over time, regardless of responsiveness classification.

Мета статті полягала в висвітленні теоретичних аспектів бюджетної децентралізації та з’ясуванні її наслідків впровадження в Україні в процесі розширення повноважень місцевих органів влади щодо прийняття управлінських рішень по формуванню та використанню бюджетних ресурсів. В статті розглянуто сутність та роль бюджетної децентралізації, проаналізовано зарубіжний досвід. Систематизовано особливості формування фінансових відносин на місцевому рівні. Показано, що бюджетна децентралізація не повинна обмежуватися виключним перерозподілом ресурсів між рівнями бюджетної системи, а повинна стимулювати територіальні громади до нарощування фінансового потенціалу та зміцнення їх самодостатності. Доведено, що бюджетна децентралізація в Україні не є завершеною, наступні етапи розпочатого процесу зміцнення матеріально-фінансової бази територіальних громад повинні лежати в площині аналізу результатів пройденого етапу реалізації бюджетної децентралізації, виявлення її  переваг та суперечностей, при цьому реалізація бюджетної децентралізації повинна опиратися на адміністративно-територіальну реформу та нову філософію державного управління.

Морфогенез сліпокишкових дивертикулів качок віком 150–240 діб
Authors: Mazurkevych T.A.
Published: June 2017

According to modern data, the immune system includes central and peripheral organs of immunogenesis. The latter includes the lymphoid tissue associated with the tunica mucosa of the digestive canal. Among organs of the birds digestive tract, immune formations are extremely well developed in the cecum, due to their functional characteristics. The lymphoid tissue of the cecum and their diverticula in ducks insufficiently studied. The cecal (apical) diverticulum is a cone-shaped end of the cecum, in the wall of which there is a significant amount of lymphoid tissue. The aim of the research was to study the morphogenesis of cecal diverticula in ducks at the age of 150–240 days. To achieve this goal, linear parameters (length and maximum thickness) of the diverticula of the right and left ceca were determined, the microscopic structure of the diverticulum wall and the content of lymphoid tissue in it were investigated, and determined the forms that represented lymphoid tissue in the diverticulum wall tunics. Accepted methods of morphological studies were used to perform the work. The linear parameters (length and maximum thickness) of the diverticula of the right and left ceca change in ducks between the ages of 150 and 240 days. The lymphoid tissue, which determines the functional features of the cecal diverticula, is determined in their tunica mucosa and tunica muscularis in all age groups of ducks. The content of lymphoid tissue decreases with increasing age of the bird: in the tunica mucosa – from 71.80±1.11% in 150-day-old ducks to 59.30 ± 4.04% in 240-day-old, in tunica muscularis – from 60.42 ± 1.68% for a 150-day-old bird to 30.54 ± 1.60% for a 240-day-old. In ducks aged from 150 to 210 days in the tunica mucosa of the diverticula of the right and left ceca, lymphoid tissue is represented by two structural forms: diffuse and secondary lymphoid nodules, and in 240-day-old – only diffuse lymphoid tissue. Lymphoid tissue is represented only by secondary lymphoid nodules in the tunica muscularis of the diverticula of the right and left ceca of all studied age groups of ducks.

Published: June 2017

Hemos usado las técnicas de calorimetría de barrido diferencial (DSC), análisis termogravimétrico (TGA) y espectroscopia de impedancias (IS) para estudiar el comportamiento de las fases del sistema NaH2PO4.H2O a temperaturas por encima de la temperatura ambiente. Los resultados de DSC muestran cinco anomalías endotérmicas  con picos alrededor de 70 oC, 120 oC, 210 oC, 325 oC y 350 oC, durante el primer barrido de calentamiento, pero ninguna anomalía aparece en el siguiente barrido de enfriamiento.Los resultados de TGA revelan que la muestra fresca de NaH2PO4.H2O pierde peso cuando es calentada por primera vez a través de las diferentes temperaturas. La resistencia eléctrica de la muestra fresca de NaH2PO4.H2O también exhibe fuertes variaciones a través de las anomalías ubicadas alrededor de 70oC y 120oC, indicando que el transporte iónico es favorecido entre 55 oC y 108 oC y entre 120 oC y 150 oC. Nosotros discutimos y atribuimos el comportamiento observado en el NaH2PO4.H2O a lo largo de todas las temperaturas donde se observan las anomalías, como una consecuencia de procesos de deshidratación de la muestra.

Abstract: The objective of this work was to estimate the phenotypic correlation and the direct and indirect effects of the aerial part components of common bean (Phaseolus vulgaris) that are associated with root distribution, in order to facilitate the indirect selection for this character. Sixteen genotypes were used, from which 12 are segregating populations in the F6 generation and four are fixed populations, which were conducted in field conditions in a randomized complete block design, with two replicates. The root system evaluation was performed according to Böhm’s method. Pearson’s phenotypic correlation was estimated by the path analysis. The characters stem diameter, leaf area index, first pod set, and root angle showed the highest positive correlations with root distribution and, therefore, may help the indirect selection for this character. The residual effect was higher than the determination coefficient, which indicates that the independent characteristics do not have a total influence on root distribution, and the low values of the determination coefficients can be attributed to environmental effects, competition for nutrients, and to different physiological mechanisms that control the expression of several genes with minor effects.
Micro-mechanical behaviour of artificially cemented sands under compression and shear
Authors: Wang W. , Nardelli V. , Coop M. R.
Published: June 2017

The mechanical behaviour of cemented sands at macro-scale has been widely studied in the past, while there is still a lack of laboratory test data for the micro-mechanical response. Therefore, a series of uniaxial compression and tangential shear tests on artificially cemented sand particles have been conducted using a microscope to observe their behaviour. First, the consistency of cemented particles with different cementing agents is discussed. Three breakage modes are proposed according to the images taken using a microscope camera. A new parameter named ‘local roundness at contact’ is introduced to emphasise the effect of contact morphology on sample strength. Moreover, the effect of bond thickness on the mechanical response of cemented particles has been investigated. Finally, the shear strength parameters of artificially cemented sand samples have been determined for two different sample diameters.

Publication Activities of Russian Universities: The Effects of Project 5–100
Authors: Poldin Oleg , Matveeva Nataliya , Sterligov Ivan , Yudkevich Mariya
Published: June 2017

We estimate the effects of the Russian University excellence program (Project 5–100) initiated by the Government in 2013 (Project 5–100) on the research performance of those leading Russian universities that received, on the competitive basis, substantial financial support within this program. While the publication output of Russian universities in general has increased in recent years, we estimate whether there is significant added value from the Program, that is, whether the extra increase in productivity takes place in selected universities. We use econometric analysis of longitudinal data applying the linear growth model with mixed effects, with the number of publications (total number, per capita, and publications in high-quality journals) as a dependent variable. We demonstrate that there is a positive significant effect of the Program that appears from the very first years of its implementation — that is, universities that received financial support demonstrate a substantial steady increase in publications measured in both total numbers and per capita (including publications in the top‑25% of journals) when compared to universities from the control group.
Fifth-Graders Moving into Adulthood: The 1960s vs the 2010s
Authors: Polivanova Katerina , Bochaver Aleksandra , Nisskaya Anastasiya
Published: June 2017

The behavior of fifth-grade students from a Moscow school was observed during 12 weeks as an iteration of a similar project undertaken in the mid‑1960s [Elkonin, Dragunova 1967]. Since the original research results were represented not as a text but as individual descriptions of 13 school students, observation criteria had to be identified. The criteria were grouped into so-called spheres, describing how teenagers behave among peers, at home, and at school. The key behavioral characteristic was the indicators of the emerging feeling of adulthood in school children, i. e. of the drive for grown-up behavior, associated with freedom and responsibility. These criteria formed the basis of the 2016 observation program. The diversity of adolescent behavioral patterns has been found to be much greater than in the original study. In addition, the linear formula of the value of learning being replaced with that of communication with peers (close interpersonal relationships) has been brought into question. As it transpires, the value of learning remains high for most fifth-graders, regardless of whether they need communication or not. Such an attitude towards learning might be encouraged by family and school, which is typical for this category of children. Four types of school students have been identified based on the indicators of their interest in learning and communication. The article cites fragments of observation protocols and semi-structured interviews. Hypotheses on how the transition to adolescence is affected by family and school characteristics have been put forward, and further observations of school students with different background have been designed.

Peer- and Coach-Created Motivational Climates in Youth Sport: Implications for Positive Youth Development of Disadvantaged Girls
Authors: Schaillée Hebe , Theeboom Marc , Van Cauwenberg Jelle
Published: June 2017

The relationship between coach- and peer-created motivational climates and Positive Youth Development is largely unexplored. This is especially true for the latter and in particular with regard to disadvantaged girls. The present study was designed to examine the relationships between perceived coach- and peer-created climates and reported developmental gains among disadvantaged girls participating in sports programmes, and to determine whether these relationships were moderated by personal characteristics. Two hundred young women aged between 12 and 22 completed a questionnaire which included the ‘Youth Experience Survey for Sport’ (MacDonald, Côté, Eys, & Deakin, 2012), the ‘Motivational Climate Scale for Youth Sports’ (Smith, Cumming, & Smoll, 2008), the ‘Peer Motivational Climate in Youth Sport Questionnaire’ (Ntoumanis & Vazou, 2005), and questions regarding participants’ socio-economic characteristics. Multilevel regression analyses were performed to take into account the hierarchical data structure. The analysis revealed that a mastery-oriented coach climate is a very strong predictor of perceived Positive Youth Development. This is based on both the number of developmental domains on which it had a significant impact and the explained variance based on the PRV values of the multi-level models. Unlike previous research on disadvantaged youth in general and disadvantaged girls in particular, the observed interaction effects did not show that disadvantaged girls necessarily gain more from their involvement in organised activities such as sport.
Complicating Gender, Sport, and Social Inclusion: The Case for Intersectionality

Published: June 2017

The following opinion piece concerns a reading of the work of Angela Davis and its application to the research on sport and social inclusion. It has the following aims: first, we use her work to argue that racism, as constituted via economics, helps to construct gender; second, we suggest that research on sport and social inclusion would do well to consider the work of Davis in forming a more complex reading of what it means to invite the participation—or inclusion—of women and girls in sport, both racialized and non-racialized.
Interculturalism and Physical Cultural Diversity in the Greater Toronto Area
Authors: Nakamura Yuka , Donnelly Peter
Published: June 2017

The Greater Toronto Area (GTA) is one of the most multicultural communities in the world. Frequently, this description is based on ethnic, linguistic, and culinary diversity. Physical cultural diversity, such as different sports, martial arts, forms of dance, exercise systems, and other physical games and activities, remains ignored and understudied. Based on a living database of the GTA’s physical cultural diversity, this study identifies the trajectories of the lifecycle of activities that have been introduced into the GTA’s physical culture by immigrants. These pathways differ based on whether the activity is offered in a separate setting, where individuals may be participating with other immigrants of the same ethnocultural group, or mixed settings, where people are participating with people from outside of their ethnocultural group. We argue that the diversity and the lifecycle trajectories of physical cultural forms in the GTA serve as evidence of interculturalism and the contribution by immigrants to the social and cultural life of Canada.

Analyzing then description of the events of the Patriotic War of 1812 in the novel of Leo Tolstoy “War and Peace”, A.S. Norov opposes them to a description which was made by the hero Yermolov of the war of 1812. The authors speculate that the polemics of A.S. Norov with the Leo Tolstoys’ point of view to the driving forces in the war of 1812 would not be so acute if it is considered in the categories of literary criticism, as a polemical discourse of the work with artistic fiction (the novel by Leo Tolstoy) with a work of documentary where fiction is excluded (wroks by A.S. Norov).

The following study considers the question of neologism phenomena in idiosyncratic speech; neologisms as a component of idiosyncratic language of the speakers with thought disorder; the analysis of the methods and principles of neologisms’ formation by the means of word-formation; the analysis of neologisms’ word-formation in idiosyncratic speech of people with thought disorder and outline the common methods of neologisms’ formation in English language.The hypothesis is that neologisms in idiosyncratic speech can be formed not only by means of violation of phonotactic rules and phonological or semantic mistakes, but also by language’s common rules of neologism’s formation. The study is based on the records of oral speech and documented writing examples of neologisms’ usage in the speech of the patients with thought disorder.

WHY ONLY SOME LIFESTYLE ACTIVISTS AVOID STATE-ORIENTED POLITICS: A CASE STUDY IN THE BELGIAN ENVIRONMENTAL MOVEMENT*
Authors: de Moor Joost , Marien Sofie , Hooghe Marc
Published: June 2017

Lifestyle politics are often defined as a political strategy used to avoid state-oriented politics. However, recent studies indicate that in some cases, lifestyle activists engage in actions that target the state. This study investigates why some lifestyle activists combine these forms of engagement, while others do not. We explore whether such differences can be explained by variations in activists' perceptions of the political opportunity structure. In particular, we consider whether perceptions of input structures and output structures offer relevant predictors for combining lifestyle politics with state-oriented actions. The article presents an in-depth case study of a Belgian environmental lifestyle movement organization, using a mixed methods approach including participant observation, qualitative interviewing, and surveys. The findings reveal that lifestyle activists' perceptions of the openness of the system matter, but that beliefs in the state's ability to act are more diverse and therefore have a stronger effect on activists' propensity for state-oriented action.

Published: June 2017

Background: Laryngeal tumours may be neoplastic or non-neoplastic. Our study aimed to analyze the incidence, clinico-etiopathological and management profile of laryngeal tumours.

Methods: This prospective study was performed on 90 cases of laryngeal tumours in the Department of Otolaryngology in a tertiary care hospital from Jan 2015 to June 2016. A detailed clinical history was taken, head & neck examination done, and supplemented with necessary imaging when required. The data thus obtained was recorded and statistically analyzed.  

Results: The ratio of benign to malignant tumours was 1:4. Of the benign tumours, 59% were vocal nodules. They were most common in the third decade (23.5%) and presented with hoarseness. Most patients were housewives (29%) and were associated with vocal abuse. All cases were managed surgically. Ninety seven percent of malignant tumours were squamous cell carcinoma, and seen in the seventh decade (37%). Forty one percent were labourers, and smoking, alcohol and laryngopharyngeal reflux were the predominant risk factors. The supraglottis was the commonest site involved, and dysphagia was the predominant presenting symptom. Majority of patients (42.5%) presented with stage IV disease. Malignant tumours were treated with radiotherapy (55%), chemoradiation (44%) and surgery (1%).

Conclusions: Vocal nodule is the commonest benign tumour of the larynx and presents with hoarseness. The supraglottis is the main subsite to be involved in laryngeal cancer, and presents with dysphagia. Most patients present with stage IV disease. Laryngopharyngeal reflux is an important risk factor for carcinoma larynx.
Dehydrochlorination of PVC Compositions During Thermal Degradation

Published: June 2017

The polyvinylchloride (PVC) differs from other polymer materials by low thermostability. The process of dehydrochlorination takes place even at low temperatures. The purpose of this investigation was to
determine the influence of different PVC additives on formation of hydrogen chloride (HCl) from thermal degradation in different gaseous fluids. It has been established that the HCl formation takes place more in
nitrogen as a medium than in air medium at a given temperature, especially for the high temperature region. Dibutyl phthalate (as a plasticizer) in 25 mass % w.r.t. PVC, reduces the mass loss due to HCl
formation by about 5%, which is the result of two interaction processes - between HCl and plastifier degradation products. It has been found that the addition of 5 mass % of stabilizer in PVC slows down the
process of dehydrochlorination and as a result the loss of mass is 2-5% less, compared to non-stabilized samples. Calcium carbonate as a filler was found to be active above 400-500 °C and reduction in mass loss
was found to be up to 15% at a temperature range of 800-900 °C. Calculation of kinetic parameters shows that the rate of dehydrochlorination depends on the composition of PVC. The activation energy of formation of HCl in air, in a temperature range of 400-600°C has been found to be 12.7, 13.3, 16.1 kJ/mol for pure, plasticized and stabilized PVC, respectively. The results reported here shall be useful for development of methods for waste utilization and their influence on the environment.

Authors: Polichtchouk Yuri M. , Yashchenko Irina G.
Published: June 2017

The study of relationships governing the variability of chemical composition of the Eurasian oils has been carried out on the basis of the statistical processing of the data on contents of total sulfur, resins,
paraffin wax and asphaltenes in oils. These indices are considered as the principal chemicals of oils chemical composition. The data processed for Eurasian continent was chosen from database on petroleum chemistry, which is create by Institute of Petroleum Chemistry of Siberian Branch of Russian Academy of Sciences and nowadays includes more than 9,000 entries of oil physical-chemical data on all main world oil-bearing basins. Latitudinal and longitudinal dependencies of the above indices of oils chemical composition were studied by methods of statistical and cluster analyses and means of geographical information system (GIS) ArcView 3.1. The results of these studies are represented on the computer maps. It is shown that properties of oils are statistically inhomogeneous in Eurasia depending on geographic position. In average, contents of total sulfur, resins and asphaltenes in crude oil increase in direction from
east to west. But the analysis doesn’t reveal longitudinal dependence of paraffin content, only a latitudinal dependence. In average, paraffin wax content in oils increases in direction from north to south. From the
analysis of the results of geozoning of oil-bearing territories using the whole complex of indices, the zones of oils that are homogenous by their properties was revealed. The results obtained may be used to solve the
problems of a rational use of hydrocarbon resources, in particular:
a) siting the oil-refining and petrochemical enterprises, b) developing the regional nets of a rational transporting of hydrocarbons and petroleum products.

Published: June 2017

Effects of phytopreparation from a plant of Limonium gmelinii were studied on livers of white breedless rats at chronic impact of cadmium sulfate and carbon tetrachloride. It was established the administration of cadmium sulfate during six months caused chronic hepatitis, while the simultaneous administration of preparation from Limonium gmelinii and cadmium sulfate did not result of destructive changes in a liver. Chronic intoxication of the animals by carbon tetrachloride during six months caused progressive postnecrotic cirrhosis. The simultaneous administration of phytopreparation and carbon tetrachloride caused postnecrotic fibrosis in the central part of hepatic lobule only. Not only dystrophic and necrobiotic processes also numerous inflammatory cell infiltrates were observed in hepatic parenchyma of animals which were treated by cadmium sulfate and carbon tetrachloride, while it was not observed at animals which were medicated with phytopreparation. Thus, on the basis of the data was concluded about hepatoprotective action of phytopreparation from Limonium gmelinii.

Objetivos: identificar a prevalência de bruxismo em universitários da Universidade Federal dos Vales do Jequitinhonha e Mucuri. Também foram investigados os fatores etiológicos, prevalência de desgaste dentário, estresse, e disfunções temporomandibulares. Material e Métodos: cinquenta e um pacientes (30 homens, 21 mulheres), selecionados aleatoriamente, foram avaliados através de questionário e exame clínico. A borda incisal e superfície oclusal dos dentes foram classificadas em: 0-sem desgaste, 1-desgaste em esmalte, 2-desgaste em dentina e 3-desgaste extenso em dentina. Dados demográficos e fatores relacionados ao bruxismo foram coletados por meio de questionário. O estresse foi avaliado pelo inventário de sintomas de estresse para adultos de Lipp. Os participantes que apresentavam desgaste dentário e hábito de apertar/ranger os dentes foram considerados como bruxômanos. Resultados: o bruxismo foi diagnosticado em 9 estudantes (17,6%). Foram avaliados 1428 dentes. Observou-se que 62,5% (255) dos dentes incisivos e 83,8% (171) dos caninos apresentavam desgaste em esmalte. Doze (23,5%) participantes apresentaram estresse. Houve associação estatisticamente significante entre bruxismo e dores musculares na região de cabeça e pescoço (p<0,001). Conclusão: a prevalência do bruxismo foi de 17,6%, sendo que os dentes mais afetados pelo desgaste foram os caninos e os incisivos. A dor muscular de cabeça e pescoço mostrou-se associada ao bruxismo.
