Avaliação da técnica de aspiração ovocitária transvaginal (Ovum Pick Up) e produção in vitro de embriões da raça nelore (Bos taurus indicus) oriundos de doadoras com alterações da fertilidade

Este experimento teve como objetivo avaliar a possibilidade da utilização de fêmeas zebuínas de elevada qualidade genética, com problemas de fertilidade, adquiridos após um programa de transferência convencional de embriões, como doadoras de ovócitos em um programa de Ovum Pick Up e Produção In Vitro de embriões. Fêmeas da raça Nelore (n=16) (Bos taurus indicus), com idade média de 11 anos e 7 meses, foram submetidas às mesmas condições de ambiente, alimentação e manejo. Estes animais foram retirados do programa de T.E. por apresentarem problemas de fertilidade (cistos ovarianos, infecções genitais, mucometra e alguns casos de repetições de cio sem causa aparente). Os animais foram divididos em dois grupos conforme o tipo de patologia: GRUPO I (n=08) composto por animais que apresentaram patologias ovarianas (cistos) e GRUPO II (n=08) formado por animais com patologias extra ovarianas, ambos os grupos foram submetidos à aspiração folicular (OPU) utilizando dois tipos de agulhas (21G ; 19G ) e pressões (55 e 70mmHg) divididos em quatro tratamentos (T1 = 55/21G; T2 = 55/19G; T3 = 70/21G e T4 = 70/19G), posteriormente os ovócitos submeteramse a PIV. Foram realizadas 149 aspirações e colhidos 879 ovócitos (5,9 4,88) onde GRAU I = 16%; GRAU II = 43%; GRAU III = 21% e GRAU IV = 20%. As médias de ovócitos colhidos no GRUPO I foram (T1 = 7,06 5,10; T2= 7,00 3,64; T3 = 10,60 6,51 e T4 = 2,78 2,59) para os animais pertencentes ao GRUPO II obteve-se (T1= 4,90 4,47; T2= 2,93 3,05; T3 = 6,11 4,11 e T4 = 2,70 2,00). Para as médiasde ovócitos viáveis os resultados foram os seguintes: (T1 = 4,35 3,01; T2 = 4,88 2,96; T3 = 6,87 3,91 e T4 = 1,89 1,90) para o GRUPO I e (T1 = 2,70 2,22; T2 =1,92 1,98; T3 = 3,47 2,27 e T4 = 2,00 1,05) para o GRUPO II. Neste experimento foram levados à PIV 538 ovócitos dos quais 161 (32,85%) clivaram e 65 (13,26%) resultaram em Mórula ou Blastocistos. A análise estatística dos resultados não demonstrou diferença significativa entre os grupos quanto a colheita ovocitária. Quando analisada somente a pressão de sucção, foi observado que o tipo de agulha está diretamente relacionado a pressão da bomba de vácuo. Os melhores resultados foram obtidos com o tratamento T3 = 70/21G, além disso pode-se observar que as melhores médias de ovócitos colhidos foram as obtidas no grupo de animais que apresentaram cistos ovarianos (GRUPO I). Desta forma, concluímos neste experimento que a utilização da técnica de OPU/PIV é uma alternativa de grande utilidade no prolongamento da vida reprodutiva de animais zebuínos com alterações na fertilidade.

Restricted stimulus control in stimulus control shaping with a capuchin monkey

Teaching the first instances of arbitrary matching-to-sample to nonhumans can prove difficult and time consuming. Stimulus control relations may develop that differ from those intended by the experimentereven when stimulus control shaping procedures are used. We present, in this study, efforts to identify sources of shaping program failure with a capuchin monkey. Procedures began with a baseline of identity matching. During subsequent shaping trials, compound comparison stimuli had two componentsone identical to and another different from the sample. The identical component was eliminated gradually by removing portions across trials (i.e., subtracting stimulus elements). The monkey performed accurately throughout shaping. At a late stage in the program, probe tests were conducted: (1) arbitrary matching trials that had all elements of the identical comparison removed and (2) other trials that included residual elements. During the test, the monkey performed at low levels on the former trials and higher levels on the latter. These results suggested that higher accuracy was due merely to continued control by the residual elements: the target arbitrary matching relations had not been learned. Thus, it appears that procedures that gradually transform identity matching baselines into arbitrary matching can fail by inadvertently shaping restricted control by residual elements. Subsequent probes at the end of the shaping series showed a successful transfer of stimulus control from identity to arbitrary matching after further programming steps apparently overcame the restricted stimulus control.

The restructuring of labour in Brazil in the 2000s: flexible work and the precarisation of working life

This article argues that the precarisation of employment that has taken place in Brazil since the 1990s has been fundamentally different in kind from earlier forms of precariousness, which took place outside the formal economy. The new forms of precariousness are taking place within the sphere of the economy controlled by transnational corporations. Although they have only reached critical mass during the 2000s, the ground was prepared by ‘post neoliberal’ restructuring, including labour law reforms, that took place in Brazil during the 1990s and introduced new forms of flexible working. The article argues that the new condition of labour now emerging in Brazil, which is a structural feature of labour under global capitalism, is characterised by psychosocial dynamics that cause: first, class desubjectivation; second, a ‘seizure’ of the waged worker's subjectivity; and third, the reduction of living labour to the status of a workforce treated as goods. Comprehending these changes necessitates a related change in the theoretical and methodological framework in which the precariousness of work is studied, one that incorporates within its scope the issues of workers' health and the quality of working life.

Adequacy of antenatal care and its relationship with low birth weight in Botucatu, Sao Paulo, Brazil: a case-control study

Background: Birth weight reflects gestational conditions and development during the fetal period. Low birth weight (LBW) may be associated with antenatal care (ANC) adequacy and quality. The purpose of this study was to analyze ANC adequacy and its relationship with LBW in the Unified Health System in Brazil.Methods: A case-control study was conducted in Botucatu, Sao Paulo, Brazil, 2004 to 2008. Data were collected from secondary sources (the Live Birth Certificate), and primary sources (the official medical records of pregnant women). The study population consisted of two groups, each with 860 newborns. The case group comprised newborns weighing less than 2,500 grams, while the control group comprised live newborns weighing greater than or equal to 2,500 grams. Adequacy of ANC was evaluated according to three measurements: 1. Adequacy of the number of ANC visits adjusted to gestational age; 2. Modified Kessner Index; and 3. Adequacy of ANC laboratory studies and exams summary measure according to parameters defined by the Ministry of Health in the Program for Prenatal and Birth Care Humanization.Results: Analyses revealed that LBW was associated with the number of ANC visits adjusted to gestational age (OR = 1.78, 95% CI 1.32-2.34) and the ANC laboratory studies and exams summary measure (OR = 4.13, 95% CI 1.36-12.51). According to the modified Kessner Index, 64.4% of antenatal visits in the LBW group were adequate, with no differences between groups.Conclusions: Our data corroborate the association between inadequate number of ANC visits, laboratory studies and exams, and increased risk of LBW newborns. No association was found between the modified Kessner Index as a measure of adequacy of ANC and LBW. This finding reveals the low indices of coverage for basic actions already well regulated in the Health System in Brazil. Despite the association found in the study, we cannot conclude that LBW would be prevented only by an adequate ANC, as LBW is associated with factors of complex and multifactorial etiology. The results could be used to plan monitoring measures and evaluate programs of health care assistance during pregnancy, at delivery and to newborns, focusing on reduced LBW rates.

A dental caries preventive program applied to children aged 5 to 8 years attending since the first year of age at the Baby Clinic of the Araçatuba Dental School, Brazil

Objective: Tooth decay is one of the more common diseases of childhood. Several studies recommend that early preventive measures must be implemented since the first years of life and continue throughout childhood and adolescence. The aim of the this study was to present results of a preventive dental program considering oral health maintenance, dental caries experience and the prevalence of dental caries relation with follow-up compliance visits. Material end method: Intraoral and interproximal radiographic exams were performed on 171 patients participants of a preventive dental program. Data regarding age, gender, previous caries experience and the frequency at which the patients attended return visits were obtained from the records. The data were analyzed statistically by the McNemar test, with the level of significance set at 1%. Result: Clinical and radiographic examination revealed that most children participating in the program had sound teeth (77.2 and 84.8%, respectively). The past dental history of the dental caries from patients included in this study showed statistical relevance when associated with the present dental caries experience and a statistical relationship was found from the absence of compliance to clinical visits and the dental caries presence. Conclusion: The preventive strategy had a positive influence on oral health maintenance in the children examined. Previous caries experience and the lack of compliance with return visits influenced the clinical oral condition of the children during participation in the preventive program.

Wildlife Master Volunteers: A Multi-County Approach to Resolving Human-Wildlife Conflicts

The Wildlife Master (WM) Program in Colorado was modeled after the highly successful Master Gardener volunteer program. In 10 highly populated suburban counties with large rural areas surrounding the Denver Metro Area, Colorado State University (CSU) Cooperative Extension Natural Resources agents train, supervise and manage these volunteers in the identification, referral, and resolution of wildlife damage issues. High quality, research-based training is provided by university faculty and other professionals in public health, animal damage control, wildlife management and animal behavior. Inquiries are responded to mainly via telephone. Calls by concerned residents are forwarded to WMs who provide general information about human-wildlife conflicts and possible ways to resolve complaints. Each volunteer serves a minimum of 14 days on phone duty annually, calling in from a remote location to a voice mail system from which phone messages can be conveniently retrieved. Response time per call is generally less than 24 hours. During 2004, more than 2,000 phone calls, e-mail messages and walk-in requests for assistance were fielded by 100 cooperative extension WMs. Calls fielded by volunteers in one county increased five-fold during the past five years, from 100 calls to over 500 calls annually. Valued at the rate of approximately $18.00 per volunteer hour, the leveraged value of each WM was about $450 in 2005, based on 25 hours of service and training. The estimated value of the program to Colorado in 2004 was over $45,000 of in-kind service, or about one full-time equivalent faculty member. This paper describes components of Colorado’s WM Program, with guides to the set-up of similar programs in other states.

The identification of the pillars of education in the class comprehensiveness in healthcare

The objective of the present study was to verify, based on the analysis of student portfolio narratives, if the four pillars of education were approached in the class "Comprehensiveness in health care", part of the integrated curriculum of the Baccalaureate in Nursing Program of the University of Sao Paulo at Ribeirao Preto College of Nursing. A qualitative, documental study was performed using 46 portfolios constructed during the classes. Data collection was performed using an assessment tool that contained items addressing cognitive and affective dimensions. The data were submitted to thematic categorical analysis using the pillars of education as predefined categories. The results show that the pillars of education were, apparently, included in the class. Despite the present study findings, no evidence was found that the expected competencies were actually discussed among students and faculty, according to the records regarding the evaluations of each pedagogical cycle of the studied class.
