Mestre Didi: um estudo sobre arte e cultura afro-brasileira

The following study aimed understanding the self-esthetic of the artist-priest Master Didi, doing so a symbolic interpretation of his sculptures, considering his relations with the ritual performance of candomblé, his creative process and his artistic, sociocultural and religious influences. The interpretation of sculptures and comprehension of the process of creation from the artist with focus on the representation of orixás allowed us to evidence the relationship established between the procedures used by the artist to produce his sculptures, the materials used in his work, the relationship of works and religion, with culture and afro-Brazilian art.

Portraits of Protestant Teens: A Report on Teenagers in Major U.S. Denominations

This report examines the religious beliefs and practices of American Protestant teenagers using new, nationally representative survey data from the National Study of Youth and Religion (NSYR). The NSYR is a major study of the religious and spiritual lives of contemporary American teens, which recently produced a book on its major findings entitled, Soul Searching: the Religious and Spiritual Lives of American Teenagers (by Christian Smith with Melinda Lundquist Denton, Oxford University Press, 2005). In addition to broadly describing the religious outlook of Protestant teenagers today — and as a more detailed, descriptive follow-up to that book — this report highlights several positive and negative experiences and evaluations of teenagers in different Protestant denominations and groupings of denominations. In brief, this report presents the following findings in these areas of interest: ♦ Religious Participation: Protestant teenagers are relatively active in religious organizations and activities, both within and beyond their churches. About one-half of all Protestant teens attend church weekly, participate in Sunday school or in a religious youth group, pray and attend a religious summer camp or retreat, though less than one-third read the Bible each week. This also means, however, that substantial numbers of Protestant teens are not actively participating in their religious traditions. Teens from conservative denominations such as Southern Baptist Convention and Assemblies of God are especially likely to regularly attend church and participate in other religious activities. ♦ Theological Beliefs: Protestant teenagers are likely to hold many traditional Christian religious beliefs. The majority of Protestant teens say they believe in God, the afterlife, angels, demons, miracles, judgment day and they view God as a personal being involved in the lives of people today. Sizable numbers of Protestant teens, on the other hand, do not hold these traditional Christian religious beliefs. Teens from conservative and black Protestant denominations are more likely than mainline Protestant teens to hold these religious beliefs. ♦ Importance of Faith: The majority of Protestant teenagers report that their religious faith is very important in their lives. Most of them also say that their families talk about religion together, that they have shared their faith with someone not of their faith and that they have had a powerful worship experience. A large minority of all Protestant teenagers, and in the case of some denominations a majority of teenagers, do not report that religious faith is very important in their lives. Teens from conservative and black Protestant denominations are particularly likely to report that faith is important in their lives. ♦ Evaluations of Churches: The majority of Protestant teenagers express relatively positive views of their churches and fellow church members. They typically report that they would continue to attend church if it were totally up to them, that they would attend a similar church if given the choice and that their current church is generally warm and welcoming. Protestant adolescents, however, do have some reservations about and problems with their churches and fellow church attendees, as spelled out in the following pages, particularly with other teenage attendees.

Current Expressions of American Jewish Identity: An Analysis of 114 Teenagers

This chapter explores the characteristics of 114 American teenagers' Jewish identities using data from the National Study of Youth and Religion (NSYR). The NSYR includes a telephone survey of a nationally representative sample of 3,290 adolescents aged 13 to 17. Jewish teenagers were over-sampled, resulting in a total of 3,370 teenage participants. Of the NSYR teens surveyed, 141 have at least one Jewish parent and 114 of them identify as Jewish. The NSYR also includes in-depth face-to-face interviews with a total of 267 U.S. teens: 23 who have at least one Jewish parent and 18 who identify as Jewish. The following analysis draws upon quantitative data from the 114 teens who identified themselves as Jewish in the face-to-face interviews.

Spiritual support for people living with HIV/AIDS: A Brazilian explorative, descriptive study

y In this exploratory and descriptive research, we identified the meaning of religion and spirituality in the experience of patients at a public health service for treatment of HIV/AIDS in a Brazilian upcountry town. Eight participants were selected through theoretical sampling. Data were collected through semistructured interviews, and analyzed by means of qualitative content analysis. The emerging themes were religion: a path to support, and God is everything. Religion, as a path that leads patients to different sources of support, included exploration of different churches, acknowledgment of guilt, and finding strength to cope with the disease, rationalization of the disease process, meeting other churchgoers, and finding God and faith. God, an important source of support, was present in prayers, in the belief in healing through faith, and in the feeling of comfort and relief. Because spirituality and religion were seen as important sources of support, in this study we that health professionals include these aspects in care planning.

Huckebein is part of a combinatorial repression code in the anterior blastoderm

The hierarchy of the segmentation cascade responsible for establishing the Drosophila body plan is composed by gap, pair-rule and segment polarity genes. However, no pair-rule stripes are formed in the anterior regions of the embryo. This lack of stripe formation, as well as other evidence from the literature that is further investigated here, led us to the hypothesis that anterior gap genes might be involved in a combinatorial mechanism responsible for repressing the cis-regulatory modules (CRMs) of hairy (h), even-skipped (eve), runt (run), and fushi-tarazu (ftz) anterior-most stripes. In this study, we investigated huckebein (hkb), which has a gap expression domain at the anterior tip of the embryo. Using genetic methods we were able to detect deviations from the wild-type patterns of the anterior-most pair-rule stripes in different genetic backgrounds, which were consistent with Hkb-mediated repression. Moreover, we developed an image processing tool that, for the most part, confirmed our assumptions. Using an hkb misexpression system, we further detected specific repression on anterior stripes. Furthermore, bioinformatics analysis predicted an increased significance of binding site clusters in the CRMs of h 1, eve 1, run 1 and ftz 1 when Hkb was incorporated in the analysis, indicating that Hkb plays a direct role in these CRMs. We further discuss that Hkb and Slp1, which is the other previously identified common repressor of anterior stripes, might participate in a combinatorial repression mechanism controlling stripe CRMs in the anterior parts of the embryo and define the borders of these anterior stripes.

Identificação do nicho de progenitores mesenquimais no fígado de embriões e fetos caninos: uma fonte de células-tronco para terapia celular

As células-tronco (CT) derivadas dos tecidos fetais (TF) foram as mais recentes descobertas entre as CT, e ultimamente tem demonstrado amplo potencial terapêutico, dentre os TF o fígado fetal (FF) apresenta grande potencial terapêutico. Este órgão durante o período fetal em mamíferos é um nicho hematopoético transitório, sendo o principal órgão responsável pela hematopoese no feto, além de contribuir com a formação do nicho definitivo na medula óssea adulta, portanto pode ser considerado um nicho de células-tronco mesenquimais (CTM) e progenitores. No entanto, pouco se sabe sobre a localização destas células no FF, desta forma o presente estudo visa identificar o nicho de CTM e progenitores em FF de cães, a fim de contribuir com as técnicas de isolamento e extração celular. Em conjunto foi realizada a verificação da expressão do fator de transcrição Oct-3/4 e da proteína delta polimerase do DNA (PCNA). Para a análise foram utilizados cinco embriões e 11 fetos caninos com idades gestacionais variando de 25-60 dias. Os resultados elucidaram a partir de 25 dias de gestação o FF apresentou-se volumoso e composto por todas as estruturas típicas, dentre elas a tríade portal, ductos biliares e ramos das artérias hepáticas. Com 30 dias de gestação foram identificados os primeiros sitos de progenitores mesenquimais (PM) enquanto que aos 60 dias os nichos estavam completamente formados com localização semelhante ao fígado adulto (FA). No entanto, células imunopositivas para Oct-3/4 não foram identificadas; sendo assim, destacamos que o FF é uma fonte de PM, apresentando-se como uma alternativa para a utilização terapêutica, bem como para os estudos da biologia do desenvolvimento das CTM e progenitores.

Morphometric analysis of fetal development of Cavia porcellus (Linnaeus, 1758) by ultrasonography: pilot study

Measurements on the growth process and placental development of the embryo and fetuses of Cavia porcellus were carried out using ultrasonography. Embryo, fetus, and placenta were monitored from Day 15 after mating day to the end of gestation. Based on linear and quadratic regressions, the following morphometric analysis showed a good indicator of the gestational age: placental diameter, biparietal diameter, renal length, and crown rump. The embryonic cardiac beat was first detected at an average of 22.5 days. The placental diameter showed constant increase from beginning of gestation then remained to term and presented a quadratic correlation with gestational age (r2 = 0.89). Mean placental diameter at the end of pregnancy was 3.5 ± 0.23 cm. By Day 30, it was possible to measure biparietal diameter, which followed a linear pattern of increase up to the end of gestation (r2 = 0.95). Mean biparietal diameter in the end of pregnancy was 1.94 ± 0.03 cm. Kidneys were firstly observed on Day 35 as hyperechoic structures without the distinction of medullar and cortical layers, thus the regression model equation between kidney length and gestational age presents a quadratic relationship (r2 = 0.7). The crown rump presented a simple linear growth, starting from 15 days of gestation, displaying a high correlation with the gestational age (r2 = 0.9). The offspring were born after an average gestation of 61.3 days. In this study, we conclude that biparietal diameter, placental diameter, and crown rump are adequate predictive parameters of gestational age in guinea pigs because they present high correlation index.

Da una sponda all'altra del Mediterraneo: percorsi migratori femminili

Until the end of the 1970s international migrants were perceived and analysed mainly within the frame of their lives in the host country, or as managing their lives and choices caught in a dilemma “between two cultures”. More recently, this approach has been challenged by an image of diasporic communities composed of individuals who “have collective homes away from home”. Migrants have become icons of hybridity and the metaphor of “border crossing”, the symbol of liberatory articulations between place, culture and identity. Migrants, it is also argued, have become transnational as they manage to live simultaneously in two countries. The research has the aim to study the migration process of the women who come from North Africa to Bologna. In particular, it investigates migrant women‘s relations with their adopted country and how their cultural practices are shaped by the transnational dimension of their lives. It was studied the journey of the migrant women’s lives across two countries and how their identities are going to change because of the experience of the migration. Migrant women are engaged in various kinds of practices and experiences through which they connect their country of origin and of residence. So this research focuses on the changes in the migrant women’s lives and the construction of their new identity. In particular, the research illustrates the development of a new notion of modernity, underlining how the migrant women construct a model of modernity that expresses a constant negotiation among diverse cultural models. The notion of modernity is not produced in opposition to tradition and religion, but is articulated with them in complex and diverse ways. The multiple ways in which migrant women understand modernity reflect their divergent identity’s renegotiation processes within the new society where they live.

Women writing Ireland, 1798 – 1921: il popular novel tra identità nazionale e immaginario religioso nelle autrici cattoliche e protestanti.

La presente tesi si concentra sul romanzo popolare irlandese scritto da donne, nel periodo compreso tra il 1798 e il 1921. Quattro sono le autrici prese in considerazione: Charlotte Elizabeth Tonna, Sydney Owenson (meglio conosciuta come Lady Morgan), Edith Somerville e Katharine Tynan, le cui vite e opere coprono un periodo storico fondamentale per l’uscita dell’Irlanda dal dominio coloniale britannico e la formazione della nazione irlandese nel sud del paese. L’interesse principale è quello di analizzare il modo in cui nei loro testi prende forma la nazione, e in particolare attraverso quali immagini e riferimenti religiosi. Il senso è quello, dunque, di rileggere tali testi prestando maggiore attenzione alla religione, uno dei principali collanti tra autrici e pubblico: all’epoca in cui l’Irlanda stava acquisendo i confini che oggi ancora mantiene, esisteva un terreno d’incontro tra discorso politico e letterario, quello della nazione, e tale terreno veniva attraversato anche dal messaggio religioso. Il fine ultimo è quello di dimostrare che la letteratura popolare non è “seconda” ad altre quanto a valori che è in grado di trasmettere e a messaggi che è in grado di veicolare: trascurarla significa non capire i meccanismi attraverso i quali una società si sviluppa e si modifica.

Asynchrone Replikation geprägter und nicht geprägter Chromosomenregionen und Expression relevanter Entwicklungsgene in Präimplantationsembryonen der Maus

Zum besseren Verständnis der epigenetischen Reprogrammierung nach der Befruchtung, wurde in der vorliegenden Studie unter Verwendung eines Interphase-FISH-Assays eine systematische Analyse des Replikationsverhaltens geprägter und nicht geprägter Chromosomenregionen in Präimplantationsembryonen der Maus durchgeführt. Dabei konnte erstmalig gezeigt werden, dass sowohl geprägte als auch nicht geprägte Chromosomen-regionen direkt nach der Befruchtung asynchron replizieren. Vier von fünf nicht geprägten Chromosomenregionen replizierten erst nach dem Zweizell-Embryostadium synchron. Eine asynchrone Replikation geprägter Regionen wurde während der gesamten Präimplantationsentwicklung und in differenzierten Zellen beobachtet. In Morula-Embryonen zeigten der in diesem Stadium nicht exprimierte Dlk1-Gtl2-Locus sowie der biallelisch exprimierte Igf2r-Locus jedoch eine Relaxation der asynchronen Replikation. In einem weiteren Projekt konnte mit Hilfe eines Multiplex-RT-PCR-Ansatzes die sensitive Detektion von multiplen Transkripten in einzelnen Zellen etabliert werden. Anschließend wurden Expressionsmuster von 17 für die epigenetische Reprogrammierung relevanten Entwicklungs-genen in Präimplantationsembryonen sowie in einzelnen Morula-Blastomeren analysiert. Der Transkriptionsfaktor Pou5f1 wurde in allen Präimplantationsembryonen und allen Morula-Blastomeren detektiert, was auf eine uniforme Reaktivierung der Pluripotenz hinweist. Dagegen variierte die mRNA-Expression verschiedener DNA-Cytosin-5-Methyltransferasen, 5-methyl-CpG-Bindeproteine sowie Enzyme der Basenexzisionsreparatur stark zwischen individuellen Zellen des gleichen Embryos und noch stärker zwischen Zellen verschiedener Embryonen. Diese Ergebnisse zeigen, dass sich das für die Reprogrammierungsmaschinerie kodierende Transkriptom zu bestimmten Entwicklungs-zeitpunkten zwischen einzelnen Blastomeren unterscheidet.

Conservare la cultura, creare una storia. Tradizione e genere nella musica di villaggio dei Banyoro e dei Batooro dell’Uganda.

La dissertazione si articola attorno all’idea di tradizione e alla concettualizzazione di genere nella musica di villaggio dei Banyoro e dei Batooro dell’Uganda occidentale. Il lavoro si sviluppa nel complesso in tre parti principali. Nella prima si presentano le trasformazioni storiche intervenute nelle relazioni di genere dal periodo precoloniale al presente e si introduce la musica di villaggio delle popolazioni considerate, ponendola a confronto con la musica di corte e con quella religiosa. La seconda sezione è dedicata allo studio dei repertori vocali e di danza di villaggio, a partire dalla documentazione realizzata con informatori anziani: di queste musiche sono considerate le caratteristiche stilistiche ed è condotta un’analisi che mira a mettere in luce le idee di genere trasmesse attraverso questi repertori. L’ultima parte del lavoro prende in considerazione le trasformazioni intervenute nel panorama musicale ugandese nell’ultimo secolo, a partire dall’influenza di musiche esterne, dall’insegnamento della musica tradizionale nelle scuole e dall’istituzione di festival scolastici e di gruppi folklorici: diverse performance attuali di canti e di danza sotto sottoposte a studio analitico. Nel complesso, si rileva una generale rifunzionalizzazione di musiche e idee di genere che si rifanno al passato, ma hanno valore soprattutto per il recupero della cultura locale nel presente,connotato dal contesto multiculturale dell’Uganda contemporanea e dalle politiche, promosse dal Governo, che favoriscono l’emancipazione femminile.

Der Einfluss assistierter Reproduktionstechniken auf die epigenetische Reprogrammierung in der fruehen Embryogenese und Gametogenese im Mausmodell

Seit der Geburt von Louise J. Brown (1978) als erstem künstlich erzeugtem Kind hat sich die Nachfrage nach assistierten Reproduktionstechniken (ART) stark erhöht. Der Anteil der nach In-vitro-Fertilisation (IVF) oder Intrazytoplasmatischer Spermieninjektion (ICSI) geborenen Kinder macht mittlerweile abhängig vom betrachteten Industrieland zwischen 1-4% an der Gesamtgeburtenzahl aus. In zahlreichen Studien korreliert eine erhöhte Prävalenz für seltene Imprinting-Erkrankungen, wie z.B. Beckwith-Wiedemann oder Angelman-Syndrom, mit der Geburt nach assistierten Reproduktionstechniken. Es ist bekannt, dass die medizinischen Interventionen zur Behandlung von Sub- und Infertilität in sehr sensitive Phasen der epigenetischen Reprogrammierung des Embryos und der Keimzellen eingreifen. In der vorliegenden Arbeit wurde untersucht, ob die ovarielle Stimulation einen Einfluss auf die epigenetische Integrität von geprägten Genen in murinen Präimplantationsembryonen hat. Die in diesem Zusammenhang entwickelte digitale Bisulfitpyrosequenzierung gewährleistet die Analyse der DNA-Methylierung auf Einzelallelebene durch eine adäquate Verdünnung der Probe im Vorfeld der PCR. Die ovarielle Induktion führte zu einem erhöhten Rate an Epimutationen des paternalen H19-Allels, sowie des maternalen Snrpn-Allels. Zudem konnte festgestellt werden, dass die Expression von drei potentiellen Reprogrammierungsgenen (Apex1, Polb, Mbd3) in Embryonen aus hormonell stimulierten Muttertieren dereguliert ist. Whole-Mount Immunfluoreszenzfärbungen für APEX1 korrelierten dessen differentielle Genexpression mit dem Proteinlevel. Anzeichen früher apoptotischer Vorgänge äußerten sich in Embryonen aus hormonell induzierten Muttertieren in der hohen Rate an Embryonen, die keines der drei Transkripte exprimierten oder weniger APEX1-positive Blastomeren aufwiesen.In einer weiteren Fragestellung wurde untersucht, ob die Kryokonservierung muriner Spermatozoen den epigenetischen Status geprägter Gene in den Keimzellen beeinflusst. Die Analyse von F1-Zweizellembryonen, die durch IVF mit den jeweiligen Spermatozoen eines Männchens generiert wurden, diente der Aufklärung möglicher paternaler Transmissionen. Insgesamt konnten keine signifikanten Auswirkungen der Kryokonservierung auf den epigenetischen Status in Spermatozoen und F1-Embryonen ermittelt werden.
