Gender-dependent language anxiety in Polish communication apprehensives

This paper analyzes the relationship between communication apprehension and language anxiety from the perspective of gender. As virtually no empirical studies have addressed the explicit influence of gender on language anxiety in communication apprehensives, this paper proposes that females are generally more sensitive to anxiety, as reflected in various spheres of communication. For this reason, language anxiety levels in communication apprehensive females should be higher, unlike those of communication apprehensive males. Comparisons between them were made using a student t test, two-way ANOVA, and post-hoc Tukey test. The results revealed that Polish communication apprehensive secondary grammar school males and females do not differ in their levels of language anxiety, although nonapprehensive males experience significantly lower language anxiety than their female peers. It is argued that the finding can be attributed to developmental patterns, gender socialization processes, classroom practices, and the uniqueness of the FL learning process, which is a stereotypically female domain.

Influence de la mécanoréception faciale sur les comportements moteurs chez l’opossum nouveau-né, Monodelphis domestica

L’opossum nait dans un état très immature, mais rampe avec ses membres antérieurs (MA) de l’orifice urogénital de la mère à une tétine, où il s’attache pour poursuivre son développement. Des informations sensorielles sont nécessaires pour guider le nouveau-né vers une tétine et déclencher son attachement. Des expériences précédentes ont montré que le système du trijumeau, dont dépend l’innervation somesthésique du museau, influence les mouvements précoces des MA. Le présent projet vise à déterminer si les mécanorécepteurs faciaux sont fonctionnels et exercent une influence sur les MA. On s’intéresse particulièrement aux cellules de Merkel, un mécanorécepteur épidermique innervé par des fibres à adaptation lente de type I (SA I). Ces cellules ont été localisées sur le pourtour du museau de l’opossum nouveau-né en utilisant un traceur cellulaire, l’AM1-43. Nous avons analysé les réponses musculaires des MA consécutives à l’application de forces calibrées au museau sur des préparations in vitro. Ces réponses sont bilatérales et simultanées, très variables, et leur intensité augmente avec la force de la stimulation. Lors de stimulations répétitives pendant 60 min, les réponses diminuent avec le temps. Le retrait de la peau faciale abolit presque ces réponses. De plus, l’application d’un antagoniste des récepteurs métabotropiques du glutamate, qui affecte l’activité des fibres SA I, ou d’un antagoniste des récepteurs purinergiques les diminue fortement, suggérant une participation des cellules de Merkel. Ces résultats soutiennent que le sens du toucher facial relayé par le système du trijumeau est fonctionnel chez l’opossum nouveau-né et qu’il pourrait influencer les mouvements des MA.

Efeito da exposição à fumaça de cigarro durante a prenhez e a lactação de ratas e sua prole sobre parâmetros séricos e morfométricos

PURPOSE: to investigate the effect of cigarette smoke exposure on body and tissue weight gain, serum parameters and milk yield during pregnancy and lactation in rats, and the impact on offspring from birth toil young adulthood. METHODS: 40 Wistar pregnant rats were randomly divided into: CG - not exposed to cigarette smoke and sacrificed at the end of pregnancy; CL - not exposed to cigarette smoke and sacrificed at the end of lactation; FG - exposed to cigarette smoke and sacrificed at the end of pregnancy; FL - exposed to cigarette smoke and sacrificed at the end of lactation. The offspring were separated by gender and divided according to their mothers' groups. Tissue weight, body weight and serum parameters were evaluated in rats and offspring. Milk yield per pup was calculated. RESULTS: body weight was decreased in FL during lactation (CL=267.0±7.2; FL=235.5±7.2 g*, *p<0.05). Adipose tissue was not detected in the CL and FL groups, and was reduced in FG compared to CG (CG=3.3±0.3; FG=2.4±0.3 g*, *p<0.05). Rats exposed to cigarette smoke had higher blood glucose levels (CG=113±17, CL=86±16, FG=177±21*, FL=178±23 mg/dL*, *p<0.05 CG versus FG e CL versus FL), CL and FL groups presented lower HDL-cholesterol with no change in total cholesterol. Finally, rats exposed to cigarette smoke had lower milk yield compared to unexposed rats (CL=6.7±0.4, FL=5.4±0.3 g*, *p<0.05). In offspring from the FG and FL groups, there was a decrease of body weight from birth to young adulthood, with no changes in gastrocnemius, liver or heart weights in any group, and adipose tissue was no detected in female offspring. There was an increase in blood glucose in offspring of both sexes from rats exposed to cigarette smoke (males: Pcg=107±10.5, Pcl=115±8.6, Pfg=148±16.8*, Pfl=172±11.2**; females: Pcg=109±27.2, Pcl=104±9.7, Pfg=134±20.0*, Pfl=126±13.3**; p<0.05 *Pcg versus Pfg and **Pcl versus Pfl). CONCLUSIONS: exposure to cigarette smoke provokes impairment of morphometric and serum parameters during pregnancy and lactation both in mothers and offspring, which is maintained during young adulthood.

Efeitos do Tai Chi Chuan na qualidade de vida, flexibilidade e equilíbrio de idosos

Introduction: The growth of the aged population in developing countries is fast. Cognitive, motion, metabolic and social injuries are associated to aging, which are potentially able to impair the quality of life of the elder population. A physical activity that provides a mental and physical welfare besides its importance to the good aging, therefore, the Tai Chi Chuan is considered an effi cient and cheap way to improve the quality of life and to reduce the physical alterations unchained by aging. Objective: To verify the effect of the Tai Chi Chuan of the quality of life, fl exibility and balance in elderly. Methods: Nine volunteers, three men (66.33 ± 13.32 years) and six women (68.67 ± 11.34 years) participated in the study. They performed the training of Tai Chi Chuan during 12 weeks, two times per week, with duration of one hour each session. The volunteers were evaluated at the beginning of the study and after the 12 weeks of training by means of the application of the questionnaire of quality of life SF-36, a scale of balance and the test to seat and to reach was applied to evaluate the fl exibility. Results: It was observed in the Tai Chi Chuan training improvement of the balance and fl exibility; however, the quality of life did not present signifi cant difference. Conclusion: These fi ndings allow us to conclude that the Tai Chi Chuan was effi cient in the improvement of the equilibrium and the fl exibility of elder people; however, it did not modify the Quality of Life of the studied population.

Comparação da flexibilidade, qualidade de vida e capacidade funcional entre idosos ativos e sedentários dos meios urbano e rural

Introduction:The regular practice of physical activity is being used as a therapeutic resource to the elderly population, with the objective of reduction of the losses provoked by the growing old process. The home place (urban or rural) is still little explored in literature about your infl uence in the physical capacity of the elderly people. Objective: The aim of this study was to value and compare the quality of life, motion and functional capacity between physically active and sedentary elderly people, residents in the urban and rural area. Methods: Sixty people with age above 60 years old were valued, 20 physically active residents in the urban area (66,5 ± 4,32 years), 20 sedentary residents in the urban area (68,8± 7,24 years), 10 physically active residents in the rural area (64,4±2,46 years) and 10 sedentary residents in the rural area (68±5,78 years). It was realized the evaluation of the fl exibility (previous fl exon of the trunk), mobility (timed up and go test), a six-minute walk test and answered a quality of life’s questionnaire SF-36. To compare the results obtained by the two groups was used the Kruskal-Wallis test, and the signifi cant presence of the test was performed post hoc Newman-Keuls. The level of signifi cance used in statistical analysis was 5% (p<0,05).Results: It was observed that the physically active elderly people obtaine better performance on the six-minutes walk test. It wasn’t found difference in the mobility among the groups. In relation to the quality of life, the elderly residents in the rural area, were better in the component Vitally. In relation to the fl exibility the elderly residents in the urban area obtained the best results. So, we can conclude that the practice of physical activity realized by the volunteers contributed to a better functional capacity, observed by the biggest distance gone through on the walk test. The rural home place positively infl uenced the vitality control, while the fl exibility was worse presented in these elderly people.

Implicações clínicas da doença de Lyme em região facial: revisão da literatura

Lyme disease (LD) is a systemic infl ammatory changes resulting from direct action and the immune response to the spirochete Borrelia burgdoferi transmitted by inoculation of the fl ow of the genus Ixodes tick and is most commonly found in North America, Europe and Asia. This disease can lead to facial and peripheral neurological manifestations, such as Bell’s palsy, eye changes, disorders in the temporo-mandibular joint in addition to paresthesia of superior and inferior alveolar nerves. In Brazil, the diagnosis of LD is primarily based on clinical presentation, the erythema migrans skin, and epidemiological information of the patient. Recognition of the onset of the DL by health professionals is essential for the correct antibiotic treatment preventing the progression of the disease, and also relevant preventive guidelines for those living or working in endemic areas.

Qualidade de água utilizada para consumo em escolas e creches no município de São Carlos - SP

We know the importance of treating water for human consumption because changes in the physicochemical and / or biological has been associated with various health problems, the quality of water intended for human consumption must meet potability standards established by governmental decree 518/2004. The aim of this study was to evaluate the quality of water supplied schools and daycare in the city of São Carlos - SP. We selected 31 schools and kindergartens, and at intervals of 3 months, two water samples taken at three different points - network, tank and fi lter - totaling 186 samples, with an interval of three months, to verify possible differences in sampling points and at different times. The samples were evaluated for the following parameters: presence of total coliform and fecal coliform / E. coli count of heterotrophic bacteria, determination of pH, fl uoride, free residual chlorine, turbidity and color. The largest number of samples outside the standard for coliform was coming from the fi lters and the network, heterotrophic bacteria in most samples was taken out of standard fi lters. In the physical-chemical analysis of samples as many non-standard pH occurred in the network, network, and fl uoride in the fi lter pair in the fi lter to free chlorine and turbidity in the reservoir. The parameter with a larger sample size was inadequate fl uoride. We need more attention to the conservation, cleaning and maintenance of building reservoirs and fi lters in schools and kindergartens of San Carlos, since the water was considered unfi t for consumption.

An in vitro triple cell co-culture model with primary cells mimicking the human alveolar epithelial barrier

A triple cell co-culture model was recently established by the authors, consisting of either A549 or 16HBE14o- epithelial cells, human blood monocyte-derived macrophages and dendritic cells, which offers the possibility to study the interaction of xenobiotics with those cells. The 16HBE14o- containing co-culture model mimics the airway epithelial barrier, whereas the A549 co-cultures mimic the alveolar type II-like epithelial barrier. The goal of the present work was to establish a new triple cell co-culture model composed of primary alveolar type I-like cells isolated from human lung biopsies (hAEpC) representing a more realistic alveolar epithelial barrier wall, since type I epithelial cells cover >93% of the alveolar surface. Monocultures of A549 and 16HBE14o- were morphologically and functionally compared with the hAEpC using laser scanning microscopy, as well as transmission electron microscopy, and by determining the epithelial integrity. The triple cell co-cultures were characterized using the same methods. It could be shown that the epithelial integrity of hAEpC (mean ± SD, 1180 ± 188 Ω cm(2)) was higher than in A549 (172 ± 59 Ω cm(2)) but similar to 16HBE14o- cells (1469 ± 156 Ω cm(2)). The triple cell co-culture model with hAEpC (1113 ± 30 Ω cm(2)) showed the highest integrity compared to the ones with A549 (93 ± 14 Ω cm(2)) and 16HBE14o- (558 ± 267 Ω cm(2)). The tight junction protein zonula occludens-1 in hAEpC and 16HBE14o- were more regularly expressed but not in A549. The epithelial alveolar model with hAEpC combined with two immune cells (i.e. macrophages and dendritic cells) will offer a novel and more realistic cell co-culture system to study possible cell interactions of inhaled xenobiotics and their toxic potential on the human alveolar type I epithelial wall.

Prática de ensino supervisionada de Inglês e de Espanhol no Ensino Básico

O presente Relatório de Estágio tem por objetivo descrever todo o processo de aplicação de estratégias para a interiorização e consequente execução na lecionação de uma Língua Estrangeira recorrendo ao mínimo à Língua Materna, realizado no decorrer da Prática de Ensino Supervisionada (PES), no âmbito do curso de Mestrado em Ensino de Inglês e de Espanhol no Ensino Básico da Escola Superior de Educação do Instituto Politécnico de Bragança. Essa descrição implica a consequente reflexão expressa e fundamentada neste relatório. Por conseguinte, tentámos fundamentar a nossa posição através de vários posicionamentos teóricos aliados a uma componente prática forte. Deste modo, durante a PES, proporcionou-se, aos alunos, uma interação maioritariamente na Língua Estrangeira (LE) nas aulas da mesma, ainda que estivesse sempre subjacente a grande importância da língua materna na aprendizagem de uma LE. Soará impossível aprender uma LE sem qualquer tipo de exemplos e referências auditivas (como o recurso a audio e video, não se baseando única e simplesmente na intervensão do professor na LE), no entanto, e visto estar a ser dada cada vez mais importância às macrocapacidades de compreensão oral e expressão oral, defende-se uma maior prática oral na lecionação de uma LE na LE.
