Abstract: Objetivou-se com este estudo avaliar a influência da associa o de duas doses contínuas da Somatotropina Recombinante Bovina (rbST) a um protocolo de superovula o sobre a quantidade e a qualidade dos embri es produzidos, além da taxa de gesta o de embri es provenientes de doadoras tratadas com a rbST. Foram usadas seis doadoras distribuídas em três tratamentos experimentais. O primeiro, tratamento I (TI), recebeu uma dose de 500mg de rbST no dia 0 do protocolo de sincroniza o da onda folicular; o segundo, tratamento II (TII), recebeu duas doses de 500mg rbST, a primeira dose 14 dias antes do início do protocolo e a outra no dia do início do protocolo e o terceiro, tratamento zero (T0), serviu de controle. As médias do número de estruturas colhidas, embri es viáveis, taxa de viabilidade, estádio de desenvolvimento e qualidade embrionária n o diferiram estatisticamente entre os tratamentos. As taxas de gesta o das receptoras foram: TI=55,0% (22/40), TII=60,0% (27/45) e T0=34,4% (11/32). Houve diferen a significativa entre o T0 e TII. Conclui-se que a rbST melhorou as taxas de gesta o de embri es provenientes de doadoras tratadas com rbST 14 dias antes do início do protocolo e no dia do início do tratamento. The purpose of this study was to evaluate the association of two continuous doses of Recombinant Bovine Somatotropin (rbST), in a protocol of superovulation on the quantity and quality of embryos produced and to evaluate the pregnancy rate of embryos from donors treated with the rbST. Six donors were used divided into three experimental treatments. The first, treatment I (TI), received a dose of 500mg of rbST on day 0 of the protocol of synchronization of follicular wave; the second, treatment II (TII), received two doses of 500mg rbST, the first dose 14 days before the start of the protocol and the other on the start of the protocol and the third, treatment zero (T0), served as control. The means number of structures collected, viable embryos, embryo viability rate, stage of development and embryo quality did not differ significantly between treatments (P>0.05). The pregnancy rates of recipients were: TI = 55,0% (22/40), TII= 60,0% (27/45) and T0 = 34.4% (11/32). There were significant difference between T0 and TII. It is concluded that the rbST improved the pregnancy rate of embryos from donors treated with rbST 14 days before the start of the protocol and the day of starting treatment.

Abstract: This experiment happened from July 2004 to September 2005 in the Depress o Cuiabana region-MT. The objective of this study was to verify the yield and sward structure of five Brachiaria genus forages submitted to 10 and 20 cm cutting intensities. The forages were irrigated and fertilized. The cutting happened with the frequency of 30 days. The variables analyzed were forage yield, plant height, forage bulk density, leaf blade percentage, stem percentage, leaf blade/stem relation and senescence percentage. A complete randomized block design was used with treatments in a split-plot arrangement and three replications. The Mulato grass showed highest green dry matter yield (4,2 t DM/ha) followed by Xaraés palisadegrass, Signalgrass and Ruzi grass, with averages greater than 3,5 t DM/ha, while the smallest forage yield was the Marandu palisadegrass (2,9 t DM/ha). The defoliation intensity interfered in the forage structures characteristics, but cutting intensity at 20 cm favored the highest leaf blade percentage for Xaraés palisadegrass. The smallest defoliation intensity propitiated greater forage yield with higher leaf blade percentage and smaller senescence losses during the experimental period. The evaluated forages presented a potential to be used on livestock pasture-based system in the Depress o Cuiabana region, specially Mulato grass and Xaraés palisadegrass.

Abstract: Objective: to characterize assistance of 88 elderly with venous ulcers attended in the tertiary and primary levels of health service in Natal city. Methods: integrative and descriptive study, from quantitative approach, with retrospective data of patients with venous ulcers who were studied in two dissertations presented at the Post-Graduate Program in Nursing/UFRN and a search report of CNPQ. Data was carried out from 2005 to 2007 through structured interview, physical examination and observation of the exchange of dressing, being organized in Excel and transported to the SPSS 14.0. These studies were approved by the Committees of Ethics in Research of the Federal University of Rio Grande do Norte (55/05; 54/05; 196/06). Results: we studied 88 elderly, mainly female sex (68,2%), literate (81,8%), outcomes two basic salary (69,3%), (52,3%) with edema (69,3%) and pain (86,4%). The main mismatches in assistance were: dressing kit (71,6%), angiologist consultation (60,2%) and monitoring specialist (56.8%). Conclusion: the assistance was considered inappropriate, mainly in the tertiary level, fragmented, with low resolution level and integration between the levels of complexity of the Public Health System.

Abstract: the current study describes the eco-epidemiological aspects of arbovirus diseases in the municipalities (counties) of novo progresso and trair?o, para state, brazil, in the area affected by highway br-163. hemagglutination inhibition (hi) antibodies to different arboviruses were detected, with monotypic reactions to mayv and orov, two important arboviruses associated with epidemics in the amazon. igm antibodies to orov and mayv were found in human sera, suggesting recent infections by these viruses. two denv-3 strains were isolated from febrile patients in novo progresso and identified as genotype iii strains. in general, the data suggest that the area displays ideal conditions for maintenance and circulation of arboviruses, plus a population with low immunization levels. dynamic surveillance of local immigrants and wild animals is thus important, focusing on antibody prevalence and isolation of arboviruses, thereby allowing effective control of infections by these viral agents in the resident population along highway br-163 in pará state.

Abstract: this paper highlights some aspects regarding the supply of pre-school education in brazil, these last 10 years, bearing in mind the goals of the 2001 national plan for education (pne). after the period characterized by the implementation of policies aimed at integrating creches (daycare center) and pre-schools into the teaching systems, in line with the legal goals proposed after the national education law of guidelines and basis (ldben, 1996), we have perceived permanencies, redefinitions and tensions. the elements to draw up the new pne, deliberated within the conference on national education (conae), last april, resize the goals for this stage of basic education, with a more general purpose of establishing bases for a new federative pact aimed at the development of a national system of education. we wonder if the goals suggested by the conae for the education of little children consider the tendencies of access coverage observed these last 10 years and if they promote investments in the perspective of the legal goals that have been developed these last two decades.

Abstract: rocio virus (rocv) is an encephalitic flavivirus endemic to brazil. experimental flavivirus infections have previously demonstrated a persistent infection and, in this study, we investigated the persistence of rocv infection in golden hamsters (mesocricetus auratus). the hamsters were infected intraperitoneally with 9.8 ld50/0.02 ml of rocv and later anaesthetised and sacrificed at various time points over a 120-day period to collect of blood, urine and organ samples. the viral titres were quantified by real-time-polymerase chain reaction (qrt-pcr). the specimens were used to infect vero cells and rocv antigens in the cells were detected by immunefluorescence assay. the levels of antibodies were determined by the haemagglutination inhibition technique. a histopathological examination was performed on the tissues by staining with haematoxylin-eosin and detecting viral antigens by immunohistochemistry (ihc). rocv induced a strong immune response and was pathogenic in hamsters through neuroinvasion. rocv was recovered from vero cells exposed to samples from the viscera, brain, blood, serum and urine and was detected by qrt-pcr in the brain, liver and blood for three months after infection. rocv induced histopathological changes and the expression of viral antigens, which were detected by ihc in the liver, kidney, lung and brain up to four months after infection. these findings show that rocv is pathogenic to golden hamsters and has the capacity to cause persistent infection in animals after intraperitoneal infection.

Abstract: the present work aims at presenting results of empirical research about the situations of labor and employment in institutions of child education in brazil, highlighting the case of belo horizonte, capital city of minas gerais state, which offers nurseries and preschools and it is representative of brazilian urban centers. an analysis including documental sources, legislation, statistics, interviews and observations was conducted, aiming at revealing the relations between the typologies of child education establishments and the forms of recruitment, career, salary and working conditions. the situations examined referred to public education institutions (state and municipal) and private institutions, according to the categories private, communitarian, philanthropic and confessional. the studied establishments were selected, through an intentional sampling procedure, based on location and preferential public attended. information was also collected from employers - public and private - and from representations of the unions/associations of professionals, in the public and private sectors. the existence of professionals with differentiated status and formation/qualification was evident, as well as a number of modalities of labor and work relations, which reveal a process of precariousness in the professional exercise in child education. cleavages within the public sector and between public and private sectors reiterate historical inequalities in that field. however, an increased demand for professionalization is observed.

Revista da Sociedade Brasileira de Medicina Tropical , 2002,
Abstract: Toxoplasmosis is one of the most common infections all over the world. Most cases are asymptomatic, except in immunosuppressed individuals and fetuses, which can be seriously damaged. Prenatal diagnosis should be made as soon as possible since treatment of the mother can minimize fetal sequelae. Our aim in this study was to test the polymerase chain reaction technique (PCR) in 86 samples of amniotic fluid from women who seroconverted during pregnancy. DNA was amplified using external primers and, in a second step, internal primers, in a nested PCR system. Samples were also inoculated into mice and the newborn were evaluated by T. gondii serology, skull x-ray, transfontanel ultrasound, fundoscopic examination, lumbar puncture and clinical examination. PCR was positive in seven cases and negative in 79. Among PCR-positive cases, two were negative by inoculation into mice and by clinical evaluation; among PCR-negative ones, three had clinical evidence of toxoplasmosis and one was positive after inoculation into mice. PCR showed values of sensitivity = 62.5% and specificity = 97.4%; the values of inoculation into mice where 42.9% and 100%, respectively. Although PCR should not be used alone for prenatal diagnosis of congenital toxoplasmosis, it is a promising method and deserves more studies to improve its efficacy.
