Estudo representacional da participação familiar nas atividades dos centros de atenção psicossocial no município de Natal-RN

Comprehending social representations of users relatives of Psychosocial Care Centers (CAPS) from Natal-RN, about their participation in the activities of these services, was the purpose of this study. The research instrument used was a semi-structured interview, led to 28 relatives of users of East and West CAPS II, East and North CAPS-ad, involved in the Relative Therapeutic Group, in Relative Meeting, in the Assembly of Users, Technicians and Relatives, according to the therapeutic schedule of each health services, between August to November 2007. Data obtained in family and users identification were characterized with the aid of charts and boards in absolute and/or percentage values. The discursive material from the guide from interviews was submitted to the informational resource ALCESTE (Analyse Lexicale par Contexte d'un Ensemble of Segments of Texte), and analyzed on the basis of the Theory of Social Representations and Central Nucleus Theory. Most of the relatives were women, married, aged over 50 years, who participated for more than two years in CAPS activities, and a coexistence of more than 11 years with the user. From the classification system of ALCESTE were selected categories, identified by: Category 1, Treatment Improvements and Expectations; Category 2, Living User Before and After; Category 3, Activities Relevance, Contradictions and Suggestions; Category 4, Guidelines -- Psychopharmacology and Medicalization; Category 5, Family Participation and Activities; and Category 6, Therapeutic Conditions Thanks, Tips and Vulnerability. The social representation of the family exists in the desire for change, identifying that we need to promote change by the continuity of therapeutic activities and overcome the detected inconsistencies, targeted by strengthening and by the stability of improvements in living and health conditions of users, experienced in CAPS treatment. The central nucleus had corresponded to positive changes in health and living conditions of users, and the peripheral elements were constituted by family conducts before and during treatment, and the expectations of changes in activities, especially in workshops. Despite this family participation be considered important, it still does not meet conditions to promote the inclusion of family, under an emancipating point of view, capable of causing in subject the hope for autonomy, initiative, individual and collective growths, a closer and active involvement in therapeutic activities, in workshops and discussions

Fixed-time artificial insemination with estradiol and progesterone for Bos indicus cows II: Strategies and factors affecting fertility

In Experiments 1, 2, and 3, we evaluated the effects of temporary weaning (TW), equine chorionic gonadotropin (eCG), and follicle-stimulating hormone (FSH) treatments on results of it fixed-time artificial insemination (TAI) protocol in postpartum Bos indicus cows. In Experiment 1, treatment with 400 IU eCG or with TW for 48 h consistently improved pregnancy rates (PRs) at TAI, but, in Experiment 2, FSH treatment was less effective than eCG or TW. In Experiment 3, the inclusion of eCG treatment in cows subjected to TW did not improve PRs. We concluded that TW or 400 IU eCG should be included in the TAI protocol in postpartum Bos indicus cows to enhance fertility. In Experiment 4, we used records front heifers and cows treated with the proposed protocol during the 2006-2007 (n = 27,195) and 2007-2008 (n = 36,838) breeding seasons from multiple locations in Brazil to evaluate factors potentially affecting PRs. Overall PR at TAI was 49.6% (31,786 of 64,033). Pregnancy rate differed (P < 0.01) among farm within location (results ranging between 26.8% and 68.0%; P < 0.01), cow group within farm, by breed (Bos indicus, 48.3% [26,123 of 54,145]; Bos taurus, 61.7% [3652 of 5922]; and crossbred Bos indicus x Bos taurus, 50.7% [2011 of 3966]), category (nulliparous, 39.6% [2095 of 52901] suckled primiparous, 45.2% [3924 of 8677]; suckled multiparous, 51.8% [24,245 of 46,767]; and nonsuckled multiparous, 46.1% [1522 of 3299]), body condition score at TAI (<= 2.5 43.0% [3409 of 7923]; 3.0, 49.6% [18,958 of 38,229]; and >3.5, 52.7% [9419 of 17,881]). Days postpartum at beginning, of protocol did not affect PR (30 to 60 d, 47.6% [4228 of 8881]; 61 to 90 d, 51.7% 116,325 to 31,5721; and 91 to 150 d, 50.8% [7616 to 14,991]; P > 0.1). Pregnancy rate was also consistently affected (P < 0.01) by sire (results ranging from 7.2% to 77.3%) and artificial insemination technician (results ranging from 15.1% to 81.8%).

Crescimento facial espontâneo Padrão II: estudo cefalométrico longitudinal

OBJETIVO: o presente estudo cefalométrico longitudinal investigou as alterações espontâneas ocorridas em crianças com má oclusão Classe II, divisão 1, Padrão II. MÉTODOS: foram selecionadas 40 crianças, 20 meninos e 20 meninas, distribuídas na faixa etária compreendida entre 6 e 14 anos de idade. Para avaliar o comportamento das bases apicais, dos incisivos e do tecido mole, as seguintes grandezas cefalométricas foram mensuradas: SN.Ba, SNA, SNB, SND, SN.Pog, ANB, NAP, SN.PP, SN.GoGn, SN.Gn, Ar.Go.Gn, 1.PP, 1.NA, 1.SN, IMPA e ANL. As seguintes grandezas alcançaram significância estatística com o crescimento: SNB, SND,SN.Pog,ANB,NAP,SN.GoGn,SN.Gn,Ar.Go.Gn e IMPA. RESULTADOS: os resultados demonstraram que as principais alterações quantitativas registradas estavam relacionadas com o crescimento mandibular,independentemente do gênero. A mandíbula deslocou-se para frente, com tendência de rotação no sentido anti-horário e com conseqüente redução nos ângulos de convexidade facial. No entanto, as oscilações quantitativas nas grandezas cefalométricas não foram suficientes para mudar a morfologia dentofacial ao longo do período de acompanhamento. CONCLUSÃO: conclui-se, portanto, que a morfologia facial é definida precocemente e é mantida, configurando o determinismo genético na determinação do arcabouço esquelético.

Correlation between morphology and function of the upper lip: a longitudinal evaluation

In order to evaluate the relationship between the morphology of the upper lip and muscle activity in a sample of 38 subjects (17 males and 21 females) with Angle Class II division 1 malocclusions, cephalometric and electromyographic analyses were conducted. The sample was subdivided into either predominantly nose or mouth breathers. The individuals were evaluated at two different periods, with a 2 year interval. At the first observation, the subjects were 11 years to 14 years 11 months of age and at the second observation, 13 years 4 months to 16 years 6 months of age. Height and thickness of the upper lip were measured on lateral cephalograms with the aid of a digital pachymeter. For each individual, electromyographic records were obtained of the orbicularis oris superior muscle at rest and in a series of 12 movements. The electromyographic data were normalized as a function of amplitude, for achievement of the percentage value of each movement. Pearson and Spearman correlation tests were applied.The results showed some correlation between morphology and muscle function (at a confidence level of 95 per cent). However, as the values of the correlation coefficient (r) were too low to establish associations between variables, it was concluded that the dimensions of the upper lip are not correlated with muscle activity.

Tolerância de híbridos de milho ao herbicida isoxaflutole

Objetivou-se com este trabalho avaliar a tolerância de híbridos de milho ao isoxaflutole e relacionar estudos de seletividade desse herbicida conduzidos em casa de vegetação com estudos desenvolvidos em campo. em casa de vegetação, o experimento foi conduzido no delineamento de blocos ao acaso, num arranjo fatorial de 23 x 3, sendo o primeiro fator constituído por híbridos de milho e o segundo por doses do herbicida (0, 60 e 120 g ha-1). Após a aplicação do herbicida, avaliou-se a massa seca de parte aérea das plantas. em campo, o experimento foi conduzido no delineamento de blocos ao acaso, em arranjo fatorial de 5 x 3, em que os fatores foram constituídos por cinco híbridos de milho, selecionados a partir dos resultados em casa de vegetação, e três doses herbicidas (0, 60 e 120 g ha-1). Após a aplicação do herbicida, foram avaliados o crescimento e a produtividade dos híbridos. Por meio dos resultados obtidos em casa de vegetação, foi possível agrupar os híbridos em diferentes níveis de tolerância ao herbicida. Com relação à produtividade de grãos, não foi constatada interação significativa entre os híbridos e as doses herbicidas. No entanto, na média de todos os híbridos avaliados, houve efeito negativo do isoxaflutole na dose de 120 g ha-1 sobre a produtividade do milho. Assim, ao avaliar a seletividade do isoxaflutole em híbridos de milho, é necessária a etapa de campo para verificar se os tratamentos herbicidas têm influência sobre a produtividade de grãos.

Electromyographic evaluation of the upper lip according to the breathing mode: A longitudinal study

The present study aimed at analyzing and comparing longitudinally the EMG (electromyographic activity) of the superior orbicularis oris muscle according to the breathing mode. The sample, 38 adolescents with Angle Class II Division 1 malocclusion with predominantly nose (PNB) or mouth (PMB) breathing, was evaluated at two different periods, with a two-year interval between them. For that purpose, a 16-channel electromyography machine was employed, which was properly calibrated in a PC equipped with an analogue-digital converter, with utilization of surface, passive and bipolar electrodes. The RMS data (root mean square) were collected at rest and in 12 movements and normalized according to time and amplitude, by the peak value of EMG, in order to allow comparisons between subjects and between periods. Comparison of the muscle function of PNB and PMB subjects at period 1 (P1), period 2 (P2) and the variation between periods (Δ) did not reveal statistically significant differences between groups (p < 0.05). However, longitudinal evaluation of the muscle function in PNB and PMB subjects demonstrated different evolutions in the percentage of required EMG for accomplishment of the movements investigated. It was possible to conclude that there are differences in the percentage of electric activity of the upper lip with the growth of the subjects according to the breathing mode.

Compensatory canine angulation in angle class II and III patients

Abstract: The aim of this study was to evaluate the occurence of compensation in mesiodistal axial inclinations of canines in skeletal malocclusions patients. The sample consisted of 25 Angle Class II, division 1 malocclusion (group 1) and 19 Angle Class III malocclusion patients (group 2). After measurement of dental angulations through a method that associates plaster model photography and AutoCad software, comparisons between the groups were performed by T-test for independent samples. Results showed that there was no statistically significant difference (p ≤ 0.05) between groups, when maxillary canine angulations were compared. Regarding the mandibular canines, there was a statistically significant difference in dental angulation, expressed by 3.2° for group 1 and 0.15° for group 2. An upright position tendency for mandibular canines was observed in the Angle Class III sample. This configures a pattern of compensatory coronary positioning, since the angulation of these teeth makes them occupy less space in the dental arch and consequently mandibular incisors can be in a more retracted position in the sagittal plane.

In vitro evaluation of the effect of dietary acids and toothbrushing on human root dentin permeability

OBJECTIVES: The purpose of this in vitro study was to quantify the alterations in human root dentin permeability after exposure to dietary acids and to evaluate the effect of toothbrushing after acid application. METHOD AND MATERIALS: Extracted human third molars had their crowns sectioned above the CEJ, pulp tissue removed, and cervical root dentin exposed using a high-speed bur (approximately 1 mm in depth of substance loss). From each root fragment, one specimen was prepared. A total of 25 specimens were used and distributed randomly into five groups. The specimens were attached to a hydraulic pressure apparatus to evaluate the alterations of root dentin permeability after exposure to different acids. Dentin permeability was measured after the following sequential steps: (1) treatment with EDTA for 3 minutes to obtain the maximum permeability; (2) root planing to create a smear layer; (3) exposure to different acidic substances for 5 minutes (vinegar, cola drink, lemon juice, white wine, and orange juice); and (4) brushing for 3 minutes. RESULTS: All acidic substances increased dentin permeability after root planing. Lemon juice produced higher values for permeability when compared to the other substances (P = .009); moreover, orange juice showed similar results (P < .02) except when compared to vinegar (P = .12). Brushing right after acid exposure significantly reduced dentin permeability except in the vinegar group (P = .07). CONCLUSION: Under the experimental conditions, dietary acids increased root dentin permeability, and immediate brushing reduced permeability levels.

Effects of bovine somatotropin administration on growth, physiological, and reproductive responses of replacement beef heifers

This experiment compared growth, body composition, plasma IGF-I and leptin, and reproductive development of beef heifers receiving or not recombinant bovine ST (BST) beginning after weaning until the first breeding season. Fifty Angus × Hereford heifers (initial BW = 219 ± 2 kg; initial age = 208 ± 2 d), weaned at approximately 6 mo of age, were assigned to the experiment (d 0 to 210). On d 0, heifers were ranked by initial BW and age and assigned to 1) treatment with BST or 2) saline control. Heifers assigned to the BST treatment received subcutaneous (s.c.) injections containing 250 mg of sometribove zinc whereas control heifers received a 5-mL s.c. injection of 0.9% saline every 14 d. Treatments were initiated on d 14 and last administered on d 196. Heifers were maintained on separate pastures harvested for hay the previous summer according to treatment and received grass and alfalfa hay at a rate to provide a daily amount of 7.0 and 1.0 kg of DM per heifer, respectively. Heifer shrunk BW was collected on d 1 and 211 for heifer ADG calculation. Blood samples were collected weekly from d 0 to 210 for determination of plasma progesterone to estimate puberty attainment as well as plasma concentrations of IGF-I and leptin in selected samples. On d 0, 63, 133, and 189, heifers were evaluated for intramuscular marbling, LM depth, and backfat thickness via real-time ultrasonography. No treatment effects were detected (P = 0.27) for heifer ADG (0.49 vs. 0.51 kg/d for control and BST heifers, respectively; SEM = 0.02). Mean backfat thickness was lesser (P < 0.01) in BST heifers compared with control cohorts (3.56 vs. 3.92 mm, respectively; SEM = 0.08). Heifers receiving BST had greater plasma IGF-I concentrations compared with control cohorts 7 d after treatment administration (treatment × day interaction; P < 0.01). Mean plasma leptin concentrations were lesser (P = 0.05) in BST heifers compared with control cohorts (1.82 vs. 2.03 ng/mL, respectively; SEM = 0.07). Onset of puberty was hastened in BST heifers compared with control cohorts (treatment x day interaction; P = 0.04). In summary, a greater proportion of BST heifers reached puberty during the experiment compared with control cohorts, despite lesser plasma leptin concentrations, backfat thickness, and similar ADG. Hence, circulating IGF-I was positively associated with hastened puberty attainment independently of growth rate, circulating leptin concentrations, and body fat content of replacement beef heifers. © 2013 American Society of Animal Science.

Herbicide selectivity in herbaceous ornamental gardens of tagetes erecta L.

One of the major problems in landscaping in tropics is weed management. The herbaceous ornamental plant, Tagetes erecta L. (Asteraceae), is very popular for its beautiful flowers which can be used in landscape and also as cut flowers. The increase use of this plant and lack of selective herbicides led to the objective of this study to evaluate the herbicide metribuzin selectivity for this ornamental plant. The experimental design was completely randomized using four treatments (herbicide metribuzin doses: 0, 0.5, 1.0 and 1.5 L ha-1, equivalent to 0, 240, 480 and 720 g ha-1) and five replicates. The herbicide was applied over the seedling of T. erecta as pre-emergence of the weed seeds. Evaluations were performed at 7, 14, 21 and 28 days after application (DAA) by visual analysis of the toxicity symptoms over the ornamental, using the European Weed Research Council (EWRC) scale (1 to 9), where 1 is the total absence of symptoms and 9 to death plants. Polynomial regression statistical analysis was used. It was verified that, from the dose of 1.0 L ha-1, T. erecta plants died by 14 DAA, which the most of them had presented a very strong toxicity symptom; for the 0.5 L ha-1 treatment the plants had survived until 28 DAA. However, most of them already exhibited the high toxicity level, dying at 35 DAA. Thus, metribuzin was not suitable for T. erecta even at the lowest rate tested in this study.
