Piensos ricos en ácidos grasos poliinsaturados n-3 aumentan la concentración de progesterona plasmática durante la gestación y mejoran la fertilidad y el tamaño de los nacidos vivos en conejas

One hundred and twenty seven rabbit does were fed ad libitum from rearing until 2nd weaning, two isofibrous, isoenergetic and isoproteic diets supplemented with two different fat sources: 3% lard for diet C (control) or 6% of a supplement (Optomega-50; Optivite International Ltd., España) containing a 50% of ether extract and 38% of n-3 polyunsaturated fatty acids for diet P (PUFA n-3). Does were inseminated at 4.5 months of age and then, at 32 days after the first parturition. Fertility and prolificacy were determined. Blood samples were obtained in 12 does of each group at -7, 0, 7, 14, 21 and 28 days of pregnancy to determine plasma progesterone. In addition, 10 litters from each group with 10-11 kits, one day old, were measured determining their length, and their biparietal and thoracic diameters. Feed intake and prolificacy were similar in both groups. Supplementation with PUFA n-3 improved fertility at second AI. Progesterone concentrations on day 7 and 14 of pregnancy in PUFA does, and the size of their kits at birth were also increased.

O estudo das células Tγδ na manutenção da tolerância materna em vacas gestantes

O sistema imunológico materno desempenha um papel importante no estabelecimento da gestação e desenvolvimento de concepto até início do parto. A hipótese deste projeto é que há um recrutamento de células Tγδ para o endométrio ao longo da gestação que expressam citocinas que favorecem o estabelecimento e manutenção da tolerância materna a antígenos fetais durante a gestação em bovinos. Experimento I Para estudar a dinâmica populacional das células do sistema imune no sangue periférico de não lactantes não prenhes (NLNP), vacas lactantes no 1º trimestre e vacas no 3º trimestre da gestação, as PBMCs foram separadas por gradiente de densidade de Ficoll, seguido por protocolo de imunocitoquímica e analisadas em citômetro de fluxo para os anticorpos CD3+, CD4+, CD8+, CD14+, CD25+ e WC1+. As células analisadas tanto na região de linfócitos quanto na região de monócitos, não apresentaram diferença significativa entre os grupos analisados. Experimento II Para análise do perfil de expressão gênica das células Tγδ, foram coletadas amostras de sangue de vacas no 1º trimestre da gestação, vacas lactantes não prenhes (LNP) e vacas não lactantes não prenhes (NLNP). As células mononucleares foram separadas por gradiente de densidade de Ficoll e células Tγδ foram analisadas quanto ao perfil de citocinas por qRT-PCR para os genes IFNG; IL10; IL15; IL17; IL18; IL1B; IL4; IL-6; ISG15; PFR; TGFB2 e TNFA. A análise de expressão gênica mostrou tendência no aumento na expressão de IL1B, IL6 e TGFB2 em células PBMC em vacas NLNP quando comparado com vacas LNP e no 1º trimestre da gestação, enquanto que os outros genes analisados não apresentaram diferença significativa. Experimento III Fragmentos de endométrio, provenientes de abatedouro, foram coletados de vacas em 1º trimestre (33 a 35 dias de gestação), 2º trimestre (143 a 182 dias de gestação) e 3º trimestre de gestação (228 a 247 dias de gestação). Cortes congelados foram imunolocalizados e quantificados para as células do sistema imune CD3+, CD4+, CD8+, CD14+, CD18+, CD25+, CD62L+ e WC1+ por imunofluorescência. Nossos estudos mostraram aumento das células CD25+ e CD62L+ no endométrio no início da gestação. No meio da gestação, há um aumento das células WC1+ e CD14+. No final da gestação, observamos o aumento de CD14+, CD25+, CD18+ e CD62L+. Em suma, nossos dados sugerem que a modulação do sistema imune materno é específica para cada estágio da gestação, sendo que no início da gestação há um envolvimento de células T ativadas (CD25+) provavelmente para o estabelecimento de uma resposta ativa para tolerância dos antígenos fetais. Já no meio da gestação, há um recrutamento massivo de células Tγδ para o endométrio gravídico provavelmente para manter um microambiente de tolerância para o desenvolvimento fetal e no final da gestação células efetoras como macrófagos são recrutadas para o endométrio para auxiliar no processo do parto e involução uterina.

Donación voluntaria de sangre de cordón umbilical en el Hospital Universitario Virgen de la Arrixaca (2010-2011). Situación actual e influencia de las variables obstétrico-fetales

Objetivos: A principios de 2010 el Hospital Universitario Virgen de la Arrixaca puso en marcha, en el servicio de partos, el protocolo de donación voluntaria de sangre de cordón umbilical (SCU). Desde la reflexión y la autoevaluación, planteamos un análisis de nuestra situación actual a través del estudio de la influencia de las variables obstétrico-fetales en la calidad de las muestras. Métodos: Con este fin hemos planteado un trabajo de tipo observacional, descriptivo, retrospectivo y de corte transversal desde mayo de 2010 a noviembre de 2011, con el objetivo de aumentar la calidad de las unidades de SCU y optar por una gestión eficiente que haga sostenible el proyecto. Resultados: Se obtuvieron 123 donaciones potenciales de sangre de cordón y del análisis multivariable de las mismas obtuvimos una correlación positiva significativa entre el número de leucocitos, las semanas de gestación y el parto vaginal. El peso inicial de la unidad se incrementó significativamente a mayor peso del recién nacido y paridad de la donante. Conclusiones: Como conclusiones del estudio nos planteamos esbozar posibles factores predictivos que permitan seleccionar las muestras de mayor calidad y sean complemento de los actuales estándares elaborados por el Banco Público de Málaga. En este sentido nuestros resultados sugieren que en los partos con más semanas de gestación, paridad de la gestante y peso del recién nacido, así como en los partos vaginales, encontramos mayores posibilidades de obtener muestras de alta calidad.

Changes to porcine blastocyst vitrification methods and improved litter size after transfer

The objective was to improve the protocol that was used to obtain the first reported piglets from transferred vitrified and warmed zona-intact blastocysts. Blastocysts were collected from superovulated sows and gilts, centrifuged to polarize lipid, vitrified, warmed and cultured for 24 h or transferred immediately. Removing the zona pellucida after warming increased the number of cells in the surviving blastocysts (zona-free 60.8 +/- 4.3, zona-intact 39.1 +/- 2.8; P < 0.05). Thinning the zona pellucida produced similar results to zona removal. Changing the basal medium of the vitrification and warming solutions from modified PBS to phosphate buffered NCSU-23 increased the number of cells (44.7 +/- 2.2 versus 56.0 +/- 3.9, respectively; P < 0.05). Reducing the plunge temperature of the liquid nitrogen from - 196 degrees C to less than -204 degrees C improved the embryo survival rate (61.9% versus 82.9%, respectively; P < 0.05). These modifications were incorporated into the vitrification protocol that was used to vitrify and warm 105 blastocysts (that were subsequently transferred into four recipients). Three recipients became pregnant, farrowing three litters (average litter size, 5.3; 18.8% embryo survival in farrowing sows). Changing the warming protocol to using sucrose rather than ethylene glycol resulted in a trend towards improved embryo survival (73.5% versus 91.2%) but this was not statistically significant. Incorporating this modification, 203 blastocysts were vitrified, warmed and transferred into seven recipients. Five became pregnant and 36 fetuses were recovered (average litter size 7.2; 24.8% embryo survival in pregnant sows) at Day 40 of pregnancy. In conclusion, changes made to the vitrification protocol improved pregnancy rate and in vivo embryo survival compared to an earlier study using the original protocol. (c) 2005 Elsevier Inc.

Perfil de mães e o desfecho do nascimento prematuro ou termo

The birth or delivery under 37 weeks of pregnancy is considered a global public health problem, since it is seen as one of the main risk factors for neonatal morbidity and mortality, particularly in the first week of life. This study had the objective of analyzing the profile of mothers of premature and full-term babies for the outcome of birth. This is an analytical-descriptive and cross-sectional study, with a sample of 109 mothers of all the premature babies and 135 mothers of the randomly selected full-term babies, by drawing, occurred in the period from April to September 2015, in a public maternity. Data were organized on Microsoft Excel 2013; subsequently, there was the analysis of the analytical-descriptive statistics, through Statistica 10, through which the frequencies, proportions, p values, with 5% significance level, through the Chi-square test, were identified. The project was submitted to the Research Ethics Committee of the Federal University of Rio Grande do Norte, receiving a favorable opinion (nº 1047431/2015). This study has enabled us to identify that the socioeconomic profile of mothers of premature and full-term babies showed, in both, low schooling level and low income. In addition, our data point out in the two groups, before and during pregnancy, a high prevalence of sedentariness; statistical significance for overweight and obesity before and during pregnancy, with 42,22% prevalence before pregnancy of mothers of premature babies and 48,62% of mothers of full-term babies; with high blood pressure during pregnancy in 32,11% of mothers of premature babies and 17,04% of mothers of full-term babies. Moreover, pregnancy was only planned in 33,33%, and also unwanted by 21,1% of mothers of premature babies, while 40,37% of mothers of full-term babies planned pregnancy and 17,78% had unwanted pregnancy. With respect to the aggravating factor “illicit drugs”, there was consumption during pregnancy on the part of 8,26% of mothers of premature babies. The most frequent complications were: vaginal bleeding (in 43,12% of mothers of premature babies and 20% of mothers of full-term babies); urinary infection (in 44,95% of mothers of premature babies and 40% of mothers of full-term babies); and stressful pregnancy (in 62,96% of mothers of premature babies and 47,41% of mothers of full-term babies). Accordingly, babies were born with health problems in 58,10% of premature births and there was healthy birth in 96,30% of full-term babies. Therefore, the profile of mothers with obesity and overweight, unwanted pregnancy, user of illegal drugs during pregnancy, stressful pregnancy and vaginal bleeding may be associated with the birth of premature baby as unfavorable and hazardous event for the child’s health.

Reproducing Women: Female Bodily Narratives and English Patriarchies, 1600-1660

During the early Stuart period, England’s return to male monarchal rule resulted in the emergence of a political analogy that understood the authority of the monarch to be rooted in the “natural” authority of the father; consequently, the mother’s authoritative role within the family was repressed. As the literature of the period recognized, however, there would be no family unit for the father to lead without the words and bodies of women to make narratives of dynasty and legitimacy possible. Early modern discourse reveals that the reproductive roles of men and women, and the social hierarchies that grow out of them, are as much a matter of human design as of divine or natural law. Moreover, despite the attempts of James I and Charles I to strengthen royal patriarchal authority, the role of the monarch was repeatedly challenged on stage and in print even prior to the British Civil Wars and the 1649 beheading of Charles I. Texts produced at moments of political crisis reveal how women could uphold the legitimacy of familial and political hierarchies, but they also disclose patriarchy’s limits by representing “natural” male authority as depending in part on women’s discursive control over their bodies. Due to the epistemological instability of the female reproductive body, women play a privileged interpretive role in constructing patriarchal identities. The dearth of definitive knowledge about the female body during this period, and the consequent inability to fix or stabilize somatic meaning, led to the proliferation of differing, and frequently contradictory, depictions of women’s bodies. The female body became a site of contested meaning in early modern discourse, with men and women struggling for dominance, and competitors so diverse as to include kings, midwives, scholars of anatomy, and female religious sectarians. Essentially, this competition came down to a question of where to locate somatic meaning: In the opaque, uncertain bodies of women? In women’s equally uncertain and unreliable words? In the often contradictory claims of various male-authored medical treatises? In the whispered conversations that took place between women behind the closed doors of birthing rooms? My dissertation traces this representational instability through plays by William Shakespeare, John Ford, Thomas Middleton, and William Rowley, as well as in monstrous birth pamphlets, medical treatises, legal documents, histories, satires, and ballads. In these texts, the stories women tell about and through their bodies challenge and often supersede male epistemological control. These stories, which I term female bodily narratives, allow women to participate in defining patriarchal authority at the levels of both the family and the state. After laying out these controversies and instabilities surrounding early modern women’s bodies in my first chapter, my remaining chapters analyze the impact of women’s words on four distinct but overlapping reproductive issues: virginity, pregnancy, birthing room rituals, and paternity. In chapters 2 and 3, I reveal how women construct the inner, unseen “truths” of their reproductive bodies through speech and performance, and in doing so challenge the traditional forms of male authority that depend on these very constructions for coherence. Chapter 2 analyzes virginity in Thomas Middleton and William Rowley’s play The Changeling (1622) and in texts documenting the 1613 Essex divorce, during which Frances Howard, like Beatrice-Joanna in the play, was required to undergo a virginity test. These texts demonstrate that a woman’s ability to feign virginity could allow her to undermine patriarchal authority within the family and the state, even as they reveal how men relied on women to represent their reproductive bodies in socially stabilizing ways. During the British Civil Wars and Interregnum (1642-1660), Parliamentary writers used Howard as an example of how the unruly words and bodies of women could disrupt and transform state politics by influencing court faction; in doing so, they also revealed how female bodily narratives could help recast political historiography. In chapter 3, I investigate depictions of pregnancy in John Ford’s tragedy, ‘Tis Pity She’s a Whore (1633) and in early modern medical treatises from 1604 to 1651. Although medical texts claim to convey definitive knowledge about the female reproductive body, in actuality male knowledge frequently hinged on the ways women chose to interpret the unstable physical indicators of pregnancy. In Ford’s play, Annabella and Putana take advantage of male ignorance in order to conceal Annabella’s incestuous, illegitimate pregnancy from her father and husband, thus raising fears about women’s ability to misrepresent their bodies. Since medical treatises often frame the conception of healthy, legitimate offspring as a matter of national importance, women’s ability to conceal or even terminate their pregnancies could weaken both the patriarchal family and the patriarchal state that the family helped found. Chapters 4 and 5 broaden the socio-political ramifications of women’s words and bodies by demonstrating how female bodily narratives are required to establish paternity and legitimacy, and thus help shape patriarchal authority at multiple social levels. In chapter 4, I study representations of birthing room gossip in Thomas Middleton’s play, A Chaste Maid in Cheapside (1613), and in three Mistris Parliament pamphlets (1648) that satirize parliamentary power. Across these texts, women’s birthing room “gossip” comments on and critiques such issues as men’s behavior towards their wives and children, the proper use of household funds, the finer points of religious ritual, and even the limits of the authority of the monarch. The collective speech of the female-dominated birthing room thus proves central not only to attributing paternity to particular men, but also to the consequent definition and establishment of the political, socio-economic, and domestic roles of patriarchy. Chapter 5 examines anxieties about paternity in William Shakespeare’s The Winter’s Tale (1611) and in early modern monstrous birth pamphlets from 1600 to 1647, in which children born with congenital deformities are explained as God’s punishment for the sexual, religious, and/or political transgressions of their parents or communities. Both the play and the pamphlets explore the formative/deformative power of women’s words and bodies over their offspring, a power that could obscure a father’s connection to his children. However, although the pamphlets attempt to contain and discipline women’s unruly words and bodies with the force of male authority, the play reveals the dangers of male tyranny and the crucial role of maternal authority in reproducing and authenticating dynastic continuity and royal legitimacy. My emphasis on the socio-political impact of women’s self-representation distinguishes my work from that of scholars such as Mary Fissell and Julie Crawford, who claim that early modern beliefs about the female reproductive body influenced textual depictions of major religious and political events, but give little sustained attention to the role female speech plays in these representations. In contrast, my dissertation reveals that in such texts, patriarchal society relies precisely on the words women speak about their own and other women’s bodies. Ultimately, I argue that female bodily narratives were crucial in shaping early modern culture, and they are equally crucial to our critical understanding of sexual and state politics in the literature of the period.
