The purpose of the present study is to identify the dermatoglyphic and somatotypic characteristics and the physical qualities of athletes from the under-17 State volleyball team, in Rio Grande do Norte, Brazil. The sample was composed of athletes, n = 14, aged 15.0 ± 0.88 years, weight (Kg) 58.3 ± 5.90 and height (cm) 169.4 ± 7.97, members of the referred team. For data collection Cummins & Midlo s (1942), o dermatoglyphic method and Heath & Carter s (1967) somatotypic method were used and to evaluate physical qualities, 2400m, 50m, Shuttle Run, abdominal , Sargent test and medicine-ball toss were performed. Fingerprints show that the group presents genetic predisposition for the following physical qualities: explosive force and velocity. As to somatotype, the group was endo-ectomorphic. At physical evaluation the group presented low Vo2 max values and reasonable levels of explosive force, local muscular endurance, agility and velocity. We conclude that: according to the dermatoglyphic model observed, the group needs training strategies to improve coordination and agility; somatotype reveals the necessity for reducing fat levels and increasing muscular mass; the evaluation of physical qualities demonstrates the need for better physical preparation. This study traces the profile of the under-17 volleyball player from Rio Grande do Norte, with respect to genetic and somatotypic aspects and physical qualities, which will serve as a parameter for future state teams

Physical therapy has suffered of a mechanistic influence, with the superspecialization and fragmentation of learning, which interfers directly in the professional s understanding of the body, besides affecting his therapeutic performance. Worried about this reality, this research analyzed perceptions of Physical therapy students from Universidade Federal do Rio Grande do Norte and Universidade Potiguar about the human body. This is a descriptive study where 167 students were evaluated through objective and subjective responses to questionnaires designited QUEB Questionnare of understanding body evaluation. Searching the complement of the datas the QUEB open-ended was created, which gives freedom to students to answer freely. This questionnnaire was applicated on a subgroup composed by 21 students of the Health Sociology subject of the Physical therapy course. The validation process of these questionnaires included strategies of a panel of experts and face validity. The theorical reference analyzed based on the studies which favor the rejoining of knowledge represented by transdisciplinary support. The analysis of the results were performed quantitativavely and qualitatively through categorization of the responses selectioning key-words and the most expressive discourses , besides using descritive statistics interpretation. According to the responses, the body thought only thought biologically, ignoring the understanding of man as a cultural and social construction, confirming the presence of the reductionist model, with overvalorization of early specialization, technical training and purely biological and mechanical considerations of the body and its mobility. Probably, the dialogic knowledge of the body human inside Physical Therapist s learning can promote a growth of health s concept and a true activeness of Physical therapy on it, being the body a link with social environment. So, through understanding of the body as a complex form, the physical therapy will be able to attend your patients considerating their biological characteristics, but so the religious, political, social and ethics. Finally, this reflection suggests a search for a less technical vision, which allows the professional to discern more than segments of the body and which will contribute to a wider understanding of the patient and his social context, leading to greater humanization of the body , improvement in services and consequently, in the quality of life of these patients

Neste trabalho, objetivou-se determinar índices de seleção para um rebanho da raça Caracu de duplo propósito, cujo objetivo de seleção (H) incluiu a venda de bezerros desmamados e a produção de leite. As características que compuseram H foram: produção total de leite, idade ao primeiro parto, período de serviço, peso à desmama e duração da vida produtiva. Foram propostos dois índices de seleção para H. Os critérios de seleção adotados no índice 1 foram: produção de leite na primeira lactação, primeiro período de serviço, peso à desmama (PD) e perímetro escrotal. No índice 2, foram consideradas as mesmas características, sendo, entretanto, o ganho médio diário do nascimento à desmama empregado como critério de seleção para PD. As análises estatísticas para a obtenção dos componentes de (co)variâncias e das estimativas dos parâmetros genéticos e fenotípicos foram realizadas pelo método da máxima verossimilhança restrita livre de derivada, por um modelo animal (uni e bi-característica). As informações zootécnicas e genealógicas, os preços e as quantidades dos insumos e dos produtos foram obtidos no escritório da empresa estudada. Os custos de produção e as receitas da atividade pecuária foram determinados para o período de 1994 a 2000. A equação de lucro foi tomada em base anual, usando-se valores médios para número de animais por categoria, características biológicas e preços..¹ O valor econômico para cada característica foi obtido pela derivada parcial da função de lucro em relação à característica em questão. Os dois índices econômicos de seleção trariam considerável resposta para o objetivo proposto. Entretanto, o índice 1, que incluiu PD, seria um pouco mais eficiente em termos de resposta à seleção total.

Para avaliar o uso da eletroacupuntura (EA) sobre os aspectos clínicos e deambulatórios, 36 coelhos tiveram o tendão calcanear comum seccionado e, após 30 dias, receberam enxerto de peritônio bovino conservado em solução supersaturada de sal. em seguida, os animais foram distribuídos aleatoriamente em três grupos de igual número: no primeiro grupo, os coelhos foram estimulados pela EA do segundo ao 11° dia de pós-operatório (PO) (E10); no segundo grupo do 11o ao 31o dia de PO (E20) e, no terceiro grupo, os animais não foram estimulados (C). Verificou-se, nos animais do E10, durante o PO, ausência de edema e hiperemia no membro tratado pela EA. Não se observou diferença significativa (P>0,05) entre os grupos quanto ao grau de deambulação dos animais. Todos os coelhos tiveram completa recuperação da deambulação até os 51 dias de PO. A utilização da eletroacupuntura na fase precoce da cicatrização do tendão calcanear comum de coelhos impediu a formação de edema e hiperemia. O tratamento com eletroacupuntura no PO não melhorou o desempenho da deambulação.

A traça-das-crucíferas, Plutella xylostella (Lepidoptera: Plutellidae), é considerada a principal praga das brássicas no mundo, sendo o uso de inseticidas o método mais usado para o seu controle. Assim, o objetivo desta pesquisa foi selecionar isolados de Beauveria bassiana com viabilidade para utilização no controle da traça-das-crucíferas. Dezessete isolados e um produto comercial de B. bassiana foram testados. Lagartas de segundo ínstar da traça-das-crucíferas foram pulverizadas com suspensão de conídios na concentração de 10(7) conídios mL-1. Para o bioensaio de concentração letal (CL) sete concentrações espaçadas em escala logarítmica foram testadas. Os isolados CCA/UFES-4, 18, 31 e 35 foram selecionados para o bioensaio de CL por causarem mortalidade confirmada superior a 90%. O isolado padrão ESALQ-447 e o produto comercial tiveram resultados semelhantes e também foram selecionados para o bioensaio de CL. Com base nas estimativas da CL50, os isolados CCA/UFES-4, 18, 31, ESALQ-447 e o produto comercial podem ser selecionados para utilização no controle da traça-das-crucíferas.

Demand for access to higher education to put in test the education Brazilian system in view of the surplus of selective processes of public universities, people without option to pay their studies at this education level. In this context, it has arisen the University for All(Universidade para Todos)Program, the ProUni, from Ministry of Education - MEC, created by the Federal Government in 2004, and that it aims the granting of full and partial scholarships in private higher education institutions, graduate courses in sequential specific training, low-income Brazilians students who do not have higher-level degree. Created by the Provisional Measure No 213/2004 and institutionalized by Law No. 11096 of January 13, 2005, the ProUni offers, however, the exemption of some taxes to those institutions that join the program. This is one of the privileged time for the study of Social Representations by offering the researcher, a living laboratory, natural environment, the confrontation between the established and new. In time like this people are challenged to incorporate the new system to the pre-existing one, aiming it through a strangeness of what was so familiar. It is through this game of social forces that we developed the present study with 196 entering higher education, of these are 116 of selective vestibular system and 80 of the ProUni selective system. We opt by the procedures for data collection in order to have access to the circulating senses, in addition to the streamlined responses. With foundation in Abric, we perform the test the Free Association of Words, then analysed by the software and by EVOC Content of the type theme as Bardin. Besides, we require of the subjects, a writing on the study object university later analysed by the software ALCESTE. The results point out to a representation strongly rooted in social factors such as more traditional socio-cultural elements: the beliefs, values, the symbols. It is unique in both groups of subjects: among those entering by the selective ProUni system, there was a stronger anchor in that it does not make inquiries about the program. At the same time, there is a stronger presence of objectivation, entering the selective vestibular system in order that they explained with a value judgement on the programme. It is suggested further studies considering the embryonic state of social representation, as recent as the social purpose that triggered. It would be relevant even the replication of the same research with other people in order to strengthen the power of the theorising of empiria available

O presente trabalho teve por objetivo avaliar a influência de diferentes concentrações de ethephon na expressão precoce de sintomas de Guignardia citricarpa em frutos de laranjeira 'Pêra-Rio'. Para tal, frutos assintomáticos e isentos de aplicações com fungicidas, com 20 e 28 semanas após a queda de pétalas, foram coletados em área de comprovada existência da doença, no município de Conchal-SP e levados ao Laboratório de Fitopatologia da FCAV/UNESP, em Jaboticabal-SP, onde foram tratados com soluções nas seguintes doses de ethephon: i) 1,57 g L-1; ii) 2,10 g L-1; iii) 2,42 g L-1; iv) Testemunha (água). Todas acrescidas de imazalil a 0,25 g L-1, para prevenir podridões de pós-colheita. Após os tratamentos, os frutos foram mantidos em câmara incubadora para B.O.D., calibrada à temperatura de 25ºC ±1ºC, por 15 dias. Posteriormente, os frutos foram submetidos a quatro avaliações, em intervalos semanais, sendo atribuídas notas que variaram de zero (ausência de sintomas) a 6 (sintomas severos). Os dados da severidade da doença observados nos frutos colhidos prematuramente e submetidos aos diferentes tratamentos com ethephon foram comparados aos observados em frutos ensacados e não ensacados, mantidos no campo até a maturação natural. Constatou-se maior equivalência de sintomas nos frutos com idade entre 20 e 28 semanas, quando estes foram tratados com 2,10 g L-1 de ethephon e avaliados entre 28 e 35 dias. Concluiu-se que o emprego de ethephon, nestas condições, viabilizou a expressão precoce dos sintomas da mancha preta em frutos contendo infecções quiescentes de G. citricarpa, com antecedência de, pelo menos, 105 dias antes da colheita. Tal resultado constitui-se, portanto, em alternativa de grande aplicabilidade na detecção precoce de sintomas de mancha preta.

O mercado demanda, desde final da década de 20, uma tecnologia para a sexagem de espermatozóides que possa ser inserida na indústria de produção de sêmen congelado e que tenha as seguintes características: a) não altere a viabilidade espermática; b) seja compatível com a congelação do espermatozóide sexado; c) permita a sexagem de espermatozóides previamente congelados e descongelados; d) permita a produção de várias doses de sêmen sexado congelado por dia, com custo compatível ao mercado. A importância dessa tecnologia para maximizar a produção animal a um custo baixo tem sido um desafio da pesquisa a vários anos. A possibilidade de produzir, em escala comercial, doses de sêmen enriquecidas com espermatozóides X ou Y aumentará os benefícios do uso da inseminação artificial no seu papel de maximizar o progresso genético entre gerações de acordo com os requerimentos de cada programa de melhoramento animal. Diferentes rotas tecnológicas são percorridas na tentativa de selecionar-se o sexo em mamíferos, tanto nas espécies de interesse zootécnico quanto em espécies ameaçadas de extinção, animais de companhia. Neste sentido, existem duas alternativas: a separação de espermatozóides portadores do cromossomo X, daqueles portadores do cromossomo Y; ou a sexagem de embriões pré-implantados. A viabilidade da sexagem de espermatozóides em bovinos é esperada por muitos anos e os desenvolvimentos recentes tornaram essa tecnologia de aplicação commercial. Entretanto, muitas limitações ainda existem, principalmente, referente à taxa de gestação em condições de campo. Isso restringe a utilização dessa tecnologia no melhoramento genético e produção animal. Nessa palestra abordaremos os potenciais sistemas de criação e produção que poderão beneficiar-se com a sexagem de espermatozóides, quando essas limitações forem solucionadas.

In the last decades, studies on early intervention involving children with autism have suggested that there is no single intervention model capable of addressing the needs of all individuals in the spectrum. The role of parents as active intervention agents is, however, highly recommended. The More Than Words-HANEN Program has been specifically created for parents of children, under five years of age, who are in the autism spectrum. This intervention aims at improving the social competence and language comprehension of the child, as well as their parents empowerment. Until now only three studies have been performed in order to evaluate the effectiveness of the HMTW program. The purpose of this investigation is to evaluate the effects of an early intervention program inspired on HMTW model on the level of caregiver responsiveness and child communication skills. The present study adds to the existing research literature on family-centered early intervention that uses a developmental paradigm. A two year boy in risk for autism, his mother and nanny took part in this investigation, which was carried out in the child´s home in Mossoró, Rio Grande do Norte. The caretakers were given one fifty-two hours of training, divided into thirteen weekly meetings. A quasi-experimental A-B-C design (baselineintervention- follow-up) showed improvement in the caretakers level of responsiveness and meaningful social-communicative gains in the child´s response

Genetic parameters for weights (17, 942 records), obtained in intervals of 60 days, from the birth to selection (378 days of age), of 2,582 males of the Nellore breed was estimated in univariate analyses by the Maximum Restricted Likelihood method. The models of analysis models included the fixed effects of contemporary groups, month of birth, mother age and age when the weights were collected as covariate. Three models differing in random effects were tested: the model 1 (M1) was adjusted for the direct and maternal addictive genetic effects and maternal permanent environment; in model 2 (M2) the maternal genetic effect was excluded; and the model 3 (M3) was only adjusted for the direct addictive genetic effect. The test of likelihood (LRT) detected significant differences, for all the ages, of M2 and M1 in relation to the simple model (M3), evidencing the importance of the maternal effects. Except for the birth weight (0.40), low values (0.05 to 0.12) of h(2) were found for M1 and M2 until 8 months of age and, after this period, reasonable increase could be observed, reaching 0.28 until 13 months of age. The estimates of the total variance fraction, due to the effect of maternal permanent environment, were high and practically became unaffected between the models 1 and 2. Maternal effects, not necessarily decomposed (in genetic addictive and permanent environment), affected the Nellore males growth. Models that contemplate maternal effects, besides the genetic addictive direct effects, are more realistic to describe the trajectory of the variances in the initial phases of growth of Nelore male calves.

This study is an exploratory descriptive study with a quantitative approach. The objective was to identify the actions for the early detection of breast cancer conducted by the health professionals of the Family Health Strategy in the Trairi region of the State of Rio Grande do Norte, Brazil. The research was conducted in nine municipalities of the region. Data were collected by means of a questionnaire with 52 Family Health Strategy professionals, 30 nurses and 22 physicians, that work in the region. Analysis was conducted using descriptive statistics. The results were organized and discussed in three areas: Knowledge about the early detection of breast cancer; Actions for early detection detection of breast cancer, and Difficulties experienced in the screening actions for breast cancer. The results indicate that these professionals (100%) have knowledge of the signs and symptoms of breast cancer and that the majority (96,2%) conduct screening actions in accordance with the recommendations of the Ministry of Health. However, a considerable number (55,8%) of these professionals encounters difficulties while conducting the screening procedures in his work setting. The difficulties varied from those of a personal nature to those of access to the procedure, such as the unavailability of sufficient quotas of screening exams. We conclude that the majority of health professionals execute the screening actions for breast cancer in their work settings according to the recommendations of the Ministry of Health, even though they encounter difficulties in the conclusion of the mammography and ultrasound exams, essential procedures in the early detection of breast cancer. We understand that these professionals demonstrate knowledge of secondary prevention even though they do not execute all the actions necessary for early detection primarily because they are impeded by the blockage of access to exam quotas. We conclude that, in spite of the difficulties experienced, the procedures for the early detection of breast cancer are being executed by the majority of the Family Health Strategy professionals in the Trairí region, specifically the clinical examination of the breast, orientation of breast self examination, requests for mammography and ultra sound examinations. Measures are needed that can mediate the difficulties, that will permit the realization of secondary prevention procedures with the population at risk in the region. We suggest training and actualization courses on the complete screening process that includes a wide discussion of the new legislation that provides the mammography exam for women over 40 years. We believe that the acquisition of such a work perspective for the early detection of breast cancer, along with knowledge of health vigilance and of breast cancer, will enhance integral health care of women that constitutes an aim of the nurse and the family health team

One of the Primary Health Care strategies for adolescent health is the growth and development follow-up and the early detection of overweight adolescents. Even though the School Health Program in Brazil proposes to evaluate the nutritional state of the school population in the corresponding community health units, not all cities have adhered to the Program and many nurses do not recognize overweight as a problem in their territory. The objective of the study was to identify the nurse´s participation in the screening of overweight adolescent students in their work territory. Cross sectional study conducted in eight state supported schools of the municipality of Natal/RN and in four Primary Health Units. The total student population was 27.277. A stratified sample was statistically calculated based on the student population of the four city geographical zones: 112 North , 74 West; 108 East; and 78 South, totalizing 372 adolescents. The students were selected by a probability process where eight schools were first selected, two per district, until the number per subsample in each district was reached. Four primary health nurses, responsible for the health units were included. Two instruments were used for data collection, a screening questionnaire and a semi-structured interview form for questioning of the nurses. The content of both instruments was validated. Anthropometric and health data were collected from the students and analyzed with descriptive and analytical statistics. Interview data were transcribed and submitted to content analysis. The nursing diagnosis of overweight was identified in 50 (13,5%) of the adolescents and its association with consumption of foods that have cardiovascular risk (canned foods, pasta and fried food). An association of the nursing diagnosis was identified with family history (diabetes, hypertension, obesity, and kidney disease). The nurses judged that care of overweight adolescents was important but noted difficulties because of the absence of this population in the health units, because of their work overload, and the lack of school articulation. The nurses do not have impacting actions with this population and delegate the responsibility to other professionals. It is concluded that overweight is a nutritional problem relevant to the adolescent school population in Natal/RN, with a 13,5% prevalence and that it is related to food consumption with cardiovascular risk and family health history. The nurses consider overweight as an important public health problem but do not envision ways to maintain linkage with adolescents and with the school to promote the needed care
