Impacto de inimigos naturais e de fatores meteorológicos sobre uma população de Brevicoryne brassicae (L.) (Hemiptera: Aphididae) em couve

Neste estudo, visou-se avaliar o impacto de inimigos naturais e de fatores meteorológicos na população do pulgão Brevicoryne brassicae (L.), na cultura da couve, usando-se correlação simples e análise de regressão múltipla com seleção de variáveis pelo método stepwise. A amostragem de B. brassicae foi realizada por procura visual e dos inimigos naturais através de armadilhas de sucção e de solo. Formas ápteras de B. brassicae começaram a infestar a couve em julho, atingindo pico populacional em setembro. Os fatores que apresentaram correlação significativa com a população de B. brassicae, no período que abrangeu todo o levantamento populacional, foram Diaeretiella rapae (Mc'Intosh), aranhas presentes no solo, precipitação pluviométrica e umidade relativa, sugerindo que tais fatores tiveram função importante na mortalidade do pulgão. No período de maior crescimento e declínio populacional de B. brassicae, aranhas presentes no solo mostraram-se como o fator de mortalidade mais significativo relacionado com a variação da densidade populacional do pulgão.

Prática do acolhimento à pessoa idosa na atenção básica: uma estratégia de humanização

The aging of the population already is a fact, before considered a phenomenon, today, is part of the reality of the majority of the societies in the world. The present study it has as objective to analyze the practical one of the shelter developed for the team to multidiscipline for the elderly in the Strategy of Health of the Family. One is about a descriptive and exploratória inquiry, developed by means of quantitative boarding. The population of this study consisted of nineteen teams that work in the inserted ESF in the urban zone of the city of Sousa-PB, understanding a complete of 133 professionals. The collection of date was carried through through a questionnaire contends closed questions, referring to the partner-demographic date e, specific open questions. The main results indicate that the professionals of Health of the city of Sousa, PB, that had participated of this study had consisted in a complete of 76. Amongst these, 20% are nurses, followed of the odontólogos in 6%; 35% are ACS and technician of nursing with 19%. The age of the interviewed ones meets in the age band enters, 21 and 30 years, in 43%. The majority is of the feminine sex with a 84% total. Already in accordance with civil state 34% is married. If treating to the wage, the doctor has of greater of 12 wages. The participants present the percentile greater of formed time of with referring 33% of 1 the 3 years of formation. E finally, the changeable time of performance, if had detached 39% of the participants with 08 the 11 years. With regard to as if it processes the reception and attendance to the person in the ESF, we can observe that, with priority attendance was prominence with 27% of the participants, followed of a considerate attendance with 26%. Already in relation to the actions that are developed daily in the ESF, these they are come back toward the HIPERDIA with 40%, followed of actions ruled in orientation with 27%. Some actions they are carried through in accordance with the aged necessity of each (13%) and through visits domiciliary (9%). It was asked to them as the shelter was facilitated in the UBS, these had told that it is through the attention that is excused the aged one (35%), and finally, as this made it difficult age, in its majority with 37% they had not wanted to answer, followed of the lack of understanding with 26%. With this study it was possible to conclude that the practical one developed for the professionals of the ESF of the city of Sousa, PB with the elderly, is characterized by an assistance ruled in the clinical aspect, little focused in the actions that to permeate the PNH

Densidade populacional e época de plantio no crescimento e produtividade da couve-flor cv. verona 284

To study plant growth and yield of cauliflower, two field trials were carried out: the first spring-summer (Oct. 07, 2006 to Jan. 28, 2007) and the second autumn-winter (Apr. 04, 2007 to Jul. 09, 2007). The experimental design was randomized complete blocks in 4 x 4 factorial design with three replications. The following factors: line spacing (0.6, 0.8, 1.0 and 1.2 m) and plant spacing (0.4, 0.5, 0.6 and 0.7 m). The used cultivar was cv. Verona 284. The characteristics, number of leaves by plant, diameter of stem, diameter of inflorescence, inflorescence mass and yield were evaluated. With the reduction in spacing, were observed lower numbers of leaves, stem diameter, diameter and mass of the inflorescence, but there was an increase in yield. The maximum yield (23 t ha(-1)) was obtained with 0.6 x 0.4 m, ie, in higher plant population (41,667, plants ha(-1)).

Atenção à saúde da pessoa idosa na estratégia saúde da família no município de Santo Antônio/RN: um estudo de caso

According to demographic estimates, by the year 2025 Brazil will be the sixth country in the world in number of elderly. For this reason, it is a purpose of public policies to help people to reach that age being healthier. The current health care model of health surveillance through the Family Health Strategy (EFS, in portuguese) is configured as a gateway into the care of the elderly in the Unified Health System (SUS, in portuguese). It is also an area of development of practices to promote health, prevention and control of chronic nondegenerative diseases. The aim of this study was to analyze the health care of the elderly provided by ESF professionals for the achievement of a full care. The study is descriptive case study with a quantitative approach, performed in the city of Santo Antônio/RN. The population included all health professionals, who are FHS members of the city that agreed to participate of the survey, a total of 80 professionals. Data were collected using a structured questionnaire, having mostly closed questions and divided into two parts: one containing sociodemographic information of health professionals and vocational training and the other, the activities carried on by the professionals in senior care, being analyzed from a database tabulated in a spreadsheet and discussed according to the descriptive statistics in tables, graphs and charts using frequencies, medians and values of central tendency. It was verified a predominance of professionals who finished highschool, mostly female, aged from 30 to 34 years old, with training completed in the last 10 years, without being graduated in the field of geriatrics or gerontology and mostly without training in gerontology. Family members and caregivers were the components of the social support network most identified by the professionals (66.3%).The elderly access to the Family Health Basic Unit was considered by83.8% of professionals as the most important factor that interferes in the activities of health care of the elderly. Considering the inclusion of the family in care: 98.8% of professionals consider the family as one of the goals of care, but 82.5% assist the family to know their role and participate in the care of the elderly, emphasizing that no professional makes use of tools for evaluating the functionality of the family. Regarding the actions taken to assist the elderly, 91.25% have home visits program to the elderly, 88.75% use the host program; 77.5% know the habits of life, cultural, ethical and religious values of the elderly, their families and their community ;51.25% complement the activities through intersectoral actions, 50%participate in groups of living with the elderly; 33.75% keeps track and maintain updated the health information of the elderly; 11.25% of the professionals perform the Single Therapy Planning (PTS, in portuguese) and few implement the actions to promote health according to PTS; there is a deficit in the number of professional categories in the identification and monitoring of the frail older people in their households. It is concluded that the health care of the elderly developed by ESF professionals differs among the professional categories. It was identified weaknesses in the promotion of an active and healthy aging and also in the establishment of an integrated and full care of the elderly. It is recommended the adoption of permanent educational activities by the City Management, initially for ESF professionals in the the perspective of the guidelines of the National Policy of Health Care for the Elderly and later to the other professionals that are part of the health care network of the elderly, at all levels of care in the city for the development of strategies and practices that promote the improvement of the quality of healthcare for the elderly, expecting concrete and effective results in terms of promoting health within Brazilian reality

Atuação do enfermeiro no acompanhamento do crescimento e desenvolvimento da criança

The nurses assistance in monitoring the growth and development of children has been characterized mostly a service based on the biological dimension of illness, when in reality, the actions should be combined in the reorientation of care model of the Family Health Strategy. Thus, the research aimed to examine the role of nurses in the growth and development of children. This is an exploratory and descriptive, qualitative approach. The project was approved by the Ethics Committee of the Universidade Federal do Rio Grande do Norte under Opinion No. 191/2012. Data collection was developed in the Health Units from the city of Natal, RN, Brazil. Survey participants were nurses who worked in the Family Health Strategy for at least two years and who performed the monitoring of child growth and development in the health unit selected. Data were collected through an in-depth interview, and seized material from speeches was treated as categorical thematic analysis proposed by Bardin. This process revealed three themes, which were analyzed in the light of Relief Models and Process Work in Health and Nursing and discussed based on the findings literary. The results elucidated that nurses consider their performance satisfactory as it has favored the accession of mothers of children under one year nursing visits, contributing to the reduction of morbidity and mortality due to prevalent diseases, as well as the establishment of a connection between the professionals and mothers. It was shown that despite having a promotion and prevention with the use of lightweight technologies, the nurses also emphasized the care of mothers in complaints and signs and symptoms of children, followed by referrals to professionals in the unit or to other sectors. Furthermore, we found that the process of working nurses face challenges regarding the organizational structure of services and social situation of the family. Given these statements, it is observed that despite the strong interference from hegemonic health model in the performance of nurses, it is found that these professionals have been investing in promotion and prevention to injuries to children in care, with a focus on family context. Thus, nurses are embarking on making the reorientation of health care through the use of relational technologies, which has contributed to solving the integral care to the pediatric population

Efeito dos taninos condensados de forrageiras nativas do semi-árido nordestino sobre o crescimento e atividade celulolítica de Ruminococcus flavefaciens FD1

Avaliaram-se o crescimento da população, a atividade in vitro da enzima 1,4-b-endoglucanase e a taxa de digestão de celulose em culturas de Ruminococcus flavefaciens FD1 na presença de 50, 100, 200 e 400µg/ml de taninos purificado das leguminosas Mimosa hostilis (Jurema Preta), Mimosa caesalpinifolia (Sabiá) e Bauhinia cheilantha (Mororó). O crescimento bacteriano, a atividade da endoglucanase e a digestão de celulose foram fortemente inibidos pela presença dos taninos condensados purificados das três espécies, entretanto, a intensidade da inibição foi variável em função da espécie da leguminosa e da concentração de tanino.

Estimação de funções de covariância para características de crescimento da raça Tabapuã utilizando modelos de regressão aleatória

Foram utilizados 35.732 registros de peso do nascimento aos 660 dias de idade de 8.458 animais da raça Tabapuã para estimar funções de covariância utilizando modelos de regressão aleatória sobre polinômios de Legendre. Os modelos incluíram: como aleatórios, os efeitos genético aditivo direto, materno, de ambiente permanente de animal e materno; como fixos, os efeitos de grupo de contemporâneo; como covariáveis, a idade do animal à pesagem e a idade da vaca ao parto (linear e quadrática); e sobre a idade à pesagem, polinômio ortogonal de Legendre (regressão cúbica) foi considerado para modelar a curva média da população. O resíduo foi modelado considerando sete classes de variância e os modelos foram comparados pelos critérios de informação Bayesiano de Schwarz e Akaike. O melhor modelo apresentou ordens 4, 3, 6, 3 para os efeitos genético aditivo direto e materno, de ambiente permanente de animal e materno, respectivamente. As estimativas de covariância e herdabilidades, obtidas utilizando modelo bicaracter, e de regressão aleatória foram semelhantes. As estimativas de herdabilidade para o efeito genético aditivo direto, obtidas com o modelo de regressão aleatória, aumentaram do nascimento (0,15) aos 660 dias de idade (0,45). Maiores estimativas de herdabilidade materna foram obtidas para pesos medidos logo após o nascimento. As correlações genéticas variaram de moderadas a altas e diminuíram com o aumento da distância entre as pesagens. A seleção para maiores pesos em qualquer idade promove maior ganho de peso do nascimento aos 660 dias de idade.

Avaliação do crescimento de ocupação da bacia do rio Pitimbu com subsídios para estudos de possíveis impactos sobre os recursos hidricos

The Pitimbu River Watershed (PRW), belonging to Potiguar capital metropolitan area, State of Rio Grande do Norte, contributes, among other purposes, to human using and animal watering. This watershed is extremely important because, besides filling up with freshwater approximately 30% of the south part of Natal (South, East and West Zones), contributes to the river shore ecosystem equilibrium. Face to the current conjuncture, this study aims to evaluate the urban development dynamics in the PRW, applying Cellular Automata as a modeling instrument, and to simulate future urban scenarios, between 2014 and 2033, using the simulation program SLEUTH. In the calibration phase, urban spots for 1 984, 1992, 2004 and 2013 years were used, with resolution from 100 meters. After the simulation, it was found a predominance of organic growth, expanding the BHRP from existing urban centers. The spontaneous growth occurred through the fullest extent of the watershed, however the probability of effective growth should not exceed 21%. It was observed that, there was a 68% increase for the period between 2014 and 2033, corresponding to an expansion area of 1,778 ha. For 2033, the source of Pitimbu River area and the Jiqui Lake surroundings will increase more than 78%. Finally, it was seen an exogenous urban growth tendency in the watershed (outside-in). As a result of this growth, hydraulics resources will become scarcer

Estudo imuno-histoquímico da presença de miofibroblastos e da expressão do fator transformador de crescimento-beta1, interferon gama, metaloproteinase de matriz 13 e indutor de metaloproteinases de matriz em lesões odontogênicas epiteliais

Myofibroblasts are cells that exhibit a hybrid phenotype, sharing the morphological characteristics of fibroblasts and smooth muscle cells, which is acquired during a process called differentiation. These cells then start to express -SMA, a marker that can be used for their identification. Studies suggest that myofibroblasts are related to the aggressiveness of different tumors and that TGF-1 and IFN- play a role in myofibroblast differentiation, stimulating or inhibiting this differentiation, respectively. The objective of this study was to investigate the role of myofibroblasts in epithelial odontogenic tumors, correlating the presence of these cells with the aggressiveness of the tumor. Immunohistochemistry was used to evaluate the expression of TGF-1 and IFN- in myofibroblast differentiation, as well as the expression of MMP-13, which is activated by myofibroblasts, and of EMMPRIN (extracellular matrix metalloproteinase inducer) as a precursor of this MMP. The sample consisted of 20 solid ameloblastomas, 10 unicystic ameloblastomas, 20 odontogenic keratocysts, and 20 adenomatoid odontogenic tumors. For evaluation of myofibroblasts, anti- -SMA-immunoreactive cells were quantified in connective tissue close to the epithelium. Immunoexpression of TGF-1, IFN-, MMP-13 and EMMPRIN was evaluated in the epithelial and connective tissue components, attributing scores of 0 to 4. The results showed a higher concentration of myofibroblasts in solid ameloblastomas (mean of 30.55), followed by odontogenic keratocysts (22.50), unicystic ameloblastomas (20.80), and adenomatoid odontogenic tumors (19.15) (p=0.001). No significant correlation between TGF-1 and IFN- was observed during the process of myofibroblast differentiation. There was also no correlation between the quantity of myofibroblasts and MMP-13 expression. Significant correlations were found between MMP-13 and TGF-1 (r=0.087; p=0.011), between MMP- 13 and IFN- (r=0.348; p=0.003), as well as between EMMPRIN and MMP-13 (r=0.474; p<0.001) and between EMMPRIN and IFN- (r=0.393; p=0.001). The higher quantity of myofibroblasts observed in solid ameloblastomas, odontogenic keratocysts and unicystic ameloblastomas suggests that these cells are one of the factors responsible for the more aggressive biological behavior of these tumors, although the myofibroblast population was not correlated with TGF-1, IFN-, MMP-13 or EMMPRIN. The correlation between MMP- 13 and TGF-1 suggests that the latter induces the expression of this metalloproteinase. The present results also support the well-established role of EMMPRIN as an inducer of MMP-13. Furthermore, the relationship between EMMPRIN and IFN- and between MMP-13 and IFN- suggests synergism in the antifibrotic effect of these markers

O exercício físico potencializa ou compromete o crescimento longitudinal de crianças e adolescentes? Mito ou verdade?

A sociedade atual tem valorizado de forma significativa a aparência alta e esbelta. Essa constituição física tem sido reforçada desde a infância e atinge a população adolescente, que deseja enquadrar-se nos estereótipos, particularmente aqueles veiculados pela mídia. Nesse sentido, profissionais de saúde são questionados rotineiramente sobre os efeitos positivos que o exercício físico exerce sobre o crescimento longitudinal de crianças e adolescentes. Procurou-se revisar a literatura especializada a respeito dos principais efeitos que o exercício físico exerceria sobre a secreção e atuação do hormônio de crescimento (GH) nos diversos tecidos corporais, durante a infância e adolescência. Através dessa revisão, foi possível verificar que o exercício físico induz a estimulação do eixo GH/IGF-1. Embora muito se especule quanto ao crescimento ósseo ser potencializado pela prática de exercícios físicos, não foram encontrados na literatura científica específica estudos bem desenvolvidos que forneçam sustentação a essa afirmação. No tocante aos efeitos adversos advindos do treinamento físico durante a infância e adolescência, aparentemente, esses foram independentes do tipo de esporte praticado, porém resultantes da intensidade do treinamento. A alta intensidade do treinamento parece ocasionar uma modulação metabólica importante, com a elevação de marcadores inflamatórios e a supressão do eixo GH/IGF-1. Entretanto, é importante ressaltar que a própria seleção esportiva, em algumas modalidades, recruta crianças e/ou adolescentes com perfis de menor estatura, como estratégia para obtenção de melhores resultados, em função da facilidade mecânica dos movimentos. Através dessa revisão, fica evidente a necessidade de realização de estudos longitudinais, nos quais os sujeitos sejam acompanhados antes, durante e após sua inserção nas atividades esportivas, com determinação do volume e da intensidade dos treinamentos, para que conclusões definitivas relativas aos efeitos sobre a estatura final possam ser emanadas.

Este artigo propõe-se a estudar a evolução da proteção internacional dos direitos humanos da pessoa idosa e a posição do Brasil nas discussões sub-regionais, regionais e multilaterais que ocorrem na atualidade, considerando O presente contexto mundial de envelhecimento da população e os novos desafios que essa realidade implica.

População microbiana total e solubilizadora de fosfato em solo submetido a diferentes sistemas de cultivo

O objetivo deste trabalho foi avaliar o efeito de diferentes espécies de plantas, fontes de fósforo e calagem sobre a população microbiana total e solubilizadora de fosfato. Foram isolados fungos e bactérias capazes de solubilizar hidroxiapatita, proporcionando P solúvel. O experimento utilizado foi em blocos ao acaso com fatorial 3x3x2. E os fatores avaliados foram espécies de plantas (controle, braquiária e guandu), fertilizantes (controle, superfosfato simples e fosfato de rocha, ambos na dose de 400 kg ha-1 de P(2)0(5) ) e calagem (com e sem calcário). A população bacteriana cresceu pelo efeito da calagem, e a de fungos aumentou, independentemente da calagem, nas parcelas cultivadas com braquiária e fertilizadas com superfosfato. Foi constatado incremento de biomassa-P microbiana sobre o controle por influência da braquiária (23,9%), do superfosfato (30,9%) e da calagem (46,9%). O número de bactérias solubilizadoras foi favorecido pela calagem ou pelo plantio de guandu adubado com fosfato natural ou com braquiária sem adubação. Os fungos solubilizadores aumentaram na ausência de planta ou de adubação e na presença de guandu com fosfato natural. Finalmente, a calagem favoreceumais o crescimento dos fungos solubilizadores, em comparação com o controle, nos tratamentos fosfato natural, braquiária ou guandu.
