Urbanização turística em ponta negra: relações de força e processos sociais no período de 1979-2009

This master thesis aimed to investigate how the power relations operating in the tourism social processes, have shaped the urbanization of Ponta Negra district, Natal, Rio Grande do Norte - RN. The study assumes that the production of space is the result of global phenomena individualized by local forces a process of glocalization. The method used was the case study. It used primary and secondary data and information were treated using the technique of content analysis. The urbanization of Ponta Negra is inserted in the context of global process triggered in the 1970s. The Park of Dunas and Costeira Highway (PD/VC) urbanization project marks the beginning of the Tourisms since 1979. The period in focus was 1979 to 2009. The tourism was dived into four major sections time: tourism in Natal before the Coastal Highway (1939-1979); Project Parque das Dunas / Coastal Highway to the first boom in domestic tourism (1979 - 1990); the internationalization of tourism (1991-2000) and, of first "boom" to "decline" of international tourism (2001-2009). Based on the historical evolution of the tourism were elected three different social processes, able to demonstrate how relations of social forces brought in space act on them and help shape the process of urbanization of the neighborhood in question: The removal of beach hut , the soccer field Botafogo Football Club and the skyscrapers . Finally, it should summarize the research identified interests and conflicts among the actors that form the thrust of spatial transformations: cultural conflicts resulting from the imposition of social practices that differ from the taste of native; clashes between different groups that reflect the duality between use value and exchange value; and interests in land values. In addition, demonstrated that the social relations that involve the production of the area are stimulated by deep-seated societal processes historically and camouflaged by market relations and a modern facade that the city has acquired in recent times; revealed that the actors are linked in networks to increase their influence and that this influence varies mainly according to economic and political power that they or their associates hold

Cytogenetic studies of Brazilian pediatric myelodysplastic syndrome cases: challenges and difficulties in a large and emerging country

Myelodysplastic syndromes (MDS) and juvenile myelomonocytic leukemia (JMML) are rare hematopoietic stem cell diseases affecting children. Cytogenetics plays an important role in the diagnosis of these diseases. We report here the experience of the Cytogenetic Subcommittee of the Brazilian Cooperative Group on Pediatric Myelodysplastic Syndromes (BCG-MDS-PED). We analyzed 168 cytogenetic studies performed in 23 different cytogenetic centers; 84 of these studies were performed in patients with confirmed MDS (primary MDS, secondary MDS, JMML, and acute myeloid leukemia/MDS+Down syndrome). Clonal abnormalities were found in 36.9% of the MDS cases and cytogenetic studies were important for the detection of constitutional diseases and for differential diagnosis with other myeloid neoplasms. These data show the importance of the Cooperative Group for continuing education in order to avoid a late or wrong diagnosis.

Comparison of risk factors among blood donors, volunteers and replacement individuals, infected or not by hepatitis C virus

Hepatitis C is transmitted primarily parenterally by contaminated blood and is often associated with: intravenous drug abuse, invasive procedures, blood transfusions, acupuncture, tattooing, and alcohol and tobacco use. This study aimed to quantify and evaluate the risk factors among blood donors, volunteer blood donors and replacement individuals, infected or not by the C virus. The main transmission routes of C virus were identified in 55 men and 25 women (GI) monitored by the Ambulatory Unit of the Department of Tropical Diseases, Botucatu Medical School, and in 24 men and 26 women (GII), all active blood donors at the Bauru State Hospital Transfusional Agency. Both groups were similar in: tobacco and alcohol consumption, sexual behavior, tattooing and illicit drug use. The duration of alcohol and tobacco consumption and blood transfusions in GI were longer, whereas the option for steady partners, condom use, disposable materials and piercings were predominant in GII. In conclusion, the risk factors for hepatitis C demonstrate the necessity of health policies that act on the primary and secondary prevention levels (respectively, reduction of infection incidence and hepatopathy risk).

Análise do processo de internalização de propostas de educação ambiental em escolas de Ensino Médio no município de Acaraú-CE

To insert environmental education in the school is a very hard task, although the question has been largely discussed since some years ago. The main object of this research is limited to the way the contents of Environmental Education are inserted in school programs, as well as to assert that, as a law, it must be put in practice not only because it is obligatory, but because it is important to school programs, especially to Acaraú´s primary and secondary schools, having in view the importance of the natural resources in which schools are inserted and the development of ways to solve problems related to the quality of life of the dwellers of these places. It is important the study of the law 9795/99 on Environmental Education, passed on July 25th, 2005, by means of the decree no. 4.281, established in the Municipal Organic Law and other documents ruling the Environmental Education. Our purpose is to give orientation on Environmental Education to the above-mentioned schools aiming at the permanent formation about that subject, in order to constitute, in the future, a real net between school and community and to spread out concepts about sustainability. This way, poverty conditions should be faced as environmental problems, bringing about the relationship between natural resources and poverty. The making of shrimp beds, predatory fishing, swamp degradation and irregular occupation constitute elements to this research. The theoretic terms are based upon principles of Environmental Education, area sustainability and inter-disciplinarily and trans-disciplinarily in Environmental Sciences, which have been applied under the form of capacities and the presentation of documents, projects, maps, discussions and reflections about the mass social movements as a positive consequence of the implementation of this project

Saúde e saneamento no município de Galinhos-RN

The state of health and sanitation in the city de Galinhos/RN is alarming, considering that access to public water supply and sanitation is absent. This condition is further exacerbated by the demand of that area as a tourist destination, especially to celebrate the festivities as the carnival, catholic festival and activities of summer. The city population growth, at times above cited, carries the collapse of poor sanitation system. The work now directs the foregoing discussion to the links between health, sanitation and environment, understood as built environment. In this context, the understanding of socio-sanitary conditions of the council is essential in the process of examining the actions of human rebut on the quality of life of local people. Thus, we developed the analysis of primary and secondary data, to conduct a holistic analysis of the health and sanitation in the city in the existing scenario. We verified, in the course of the research, that the conditions for solve part of the problem are already evident. However, the lack of political and popular demobilization contribute to the maintenance of the status quo

Outra leitura do "outro lado":o espaço da Zona Norte em questão

It analyzes the production of the space of the North Zone of Natal/RN, of the beginning of its formation - decade of 1970 - a present time, under the optics of the urban planning and of the administration of the territory. Inside of that path, it examines the interests that orientated the "creation" of the referred space, as support to the process of urban planning and of administration of the territory; as well as the recent processes that evidence a new partner-space dynamics, which is configured, now as an incipient insert of the North Zone to the context natalense urban-space, now as a "reedition" of its report process of partner-space segregation. It stands out that, while in the beginning of the formation of the North Zone, the State was made the main actor, making possible the expansion of the capital in the north sense of the city of Natal, through the implantation of the Industrial District of Natal (DIN) and of the expansion of the habitational politics of the House of Financial System (SFH); at the present time, the new space processes are configured through the economical inclination, through expansion of the tertiary section in the city of Natal. It is based in bibliography regarding the theme in focus, in primary and secondary sources, as well as in processes and forms that were unchained in the North Zone along the research. It analyzes the North Zone then in its group, the one that makes possible apprehend the inherent conflicts to the process of production-appropriation of the urban space, for the several social actors - the State, the capital and the society - that dispute the control of the production of the space according themselves their interests

Ovarian activity and plasma concentrations of progesterone and estradiol during pregnancy in jennies

The objectives of this study were to determine ovarian activity (with ultrasound) and plasma concentrations of progesterone and estradiol during pregnancy in jennies. There was considerable ovarian activity during the second month of pregnancy. Secondary corpora lutea (total of 2 to 7 per jenny) were formed (mainly by luteinization) starting on Day 41.8 +/- 1.0 (range Days 38 to 46; ovulation = Day 0). The echogenicity of the primary and secondary corpora lutea gradually decreased during pregnancy. Plasma progesterone concentrations increased between Days 0 and 10 (0.9 and 19.9 ng/mL, respectively), gradually decreased to Day 30 (12.1 ng/mL), increased between Days 30 and 40 (plateau, at approximately 17 ng/mL), gradually declined from Days 110 to 160 (nadir of approximately 6 ng/mL), and remained nearly constant until increasing again just before parturition. Plasma estradiol concentrations increased gradually from Day 65, peaked (1.2 ng/mL) on Day 165 (greater than or equal to 1 ng/mL on Days 150 to 210), and decreased thereafter, with very low concentrations during the last 20 d before parturition. Ovarian function and hormone profiles were generally similar to those previously reported during pregnancy in mares. (C) 1998 by Elsevier B.V.

Morphologic and quantitative evaluation of preantral follicles of buffalo (Bubalus bubalis) in different reproductive phases

The objectives of the present study were to estimate the population of the normal and degenerated preantral follicles of buffaloes in different reproductive phases and to classify the different types of degeneration of ovarian preantral follicles. For this, 18 ovaries were divided in three groups: prepubertal, non pregnat and pregnant adult females. The ovaries were collected from a slaughterhouse (Frigol - Brazil) and processed for classic histological examination. The follicular population was estimated according to Cahill et al. (1979) and calculated according to Gougeon & Chainy (1987). Young buffaloes, pregnant and non pregnat adults presented an average number of 15.5, 3.7 and 8.9 preantral follicles with normal morphology and type I (the degeneration was observed just in oocyte) and II (oocyte and granulosa cells were degenerated) degeneration, respectively. This experiment demonstrated that the proportions of primordial, primary and secondary follicles were affected by reproductive phase. A significant difference was observed considering the proportions of preantral follicles with normal morphology and Type I degeneration in all reproductive phases evaluated. The primary follicles presented more percentage of Type I degeneration that the others follicles and the primordial and primary follicles presented more percentage of Type II degeneration in three reproductive phases evaluated.

Testicular interstitial cells, and steroidogenic detection in the protogynous fish, Synbranchus marmoratus (Teleostei, Synbranchidae)

The swamp eel, Synbranchus marmoratus, is a freshwater protogynic diandric species. Primary males develop directly as males while secondary males arise from the sex reversal of females. Fishes from Argentine and Brazil inland waters were collected, examined and compared for this study. In order to characterize the interstitial testicular compartment, light and electron microscopy techniques and an enzyme histochemical examination for steroidogenic cells detection were used. The interstitial compartment of S. marmoratus is composed of Leydig and myoid cells, collagen fibers, blood cells, macrophages,and amyelinic nerves. At the ultrastructural level, no differences were observed in the interstitial tissue, either between specimens from the different sampling sites or between primary and secondary males. Leydig cells are present in all testes examined throughout the year. A cytoplasmatic reaction of 3beta-HSD was detected only in Leydig cells during sex reversal and in both type of males, mainly during the regressed and early maturation classes (autumn and winter). Leydig cells possess the typical fine structural characteristics associated with steroidogenesis. Furthermore, in both type of males, during sex reversal and after the spawning period, the number of granulocytes and macrophages present in the testes increased, suggesting that they could be involved in phagocytosis and resorption of damaged cells.

Follicular diameter range based on morphological features in Synbranchus marmoratus (Bloch, 1795) (Teleostei, Synbranchiformes, Synbranchidae) from the South-central region of Brazil

The morphological characteristics of Synbranchus marmoratus female germ cells in various development stages were described in details; then measurements of ovarian follicle diameters were taken from primary and secondary growth as during these development stages the oocyte size varied considerably along the fish growth. The results were correlated to total fish length, using the individuals division in six size classes. It was possible to group oocytes by stages according to histological characteristics but not according to morphometric diameter, as there was a wide variation in diameter in each stage and overlap between different maturation stages. These data make available new information on the reproductive biology of Synbranchidae. (c) 2004 Published by Elsevier Ltd.

A new vision of the origin and the oocyte development in the Ostariophysi applied to Gymnotus sylvius (Teleostei: Gymnotiformes)

Tendo por base os novos conhecimentos oriundos de recentes estudos com Perciformes marinho, a origem e o desenvolvimento dos oócitos no Ostariophysi Gymnotus sylvius são aqui descritos. da mesma maneira que ocorre nos Perciformes, em Gymnotus sylvius as oogônias são encontradas no epitélio germinativo que margeia as lamelas ovígeras. No início da foliculogênese, a proliferação das oogônias e sua entrada em meiose dão origem a ninhos de células germinativas que se projetam em direção ao estroma ovariano, a partir do epitélio germinativo. Os ninhos e o epitélio germinativo são suportados pela mesma membrana basal que os separa do estroma. Coincidindo com a paralisação da meiose os oócitos, presentes nos ninhos, são separados uns dos outros por processos citoplasmáticos das células pré-foliculares. As células pré-foliculares derivam do epitélio germinativo sendo, portanto, inicialmente células epiteliais. Durante a foliculogênese, ao mesmo tempo em que envolvem os oócitos individualizando-os, as células pré-foliculares sintetizam a membrana basal ao seu redor. Os oócitos entram em crescimento primário ainda dentro dos ninhos. Ao término da foliculogênese, o oócito e as células foliculares que compõem o folículo são circundados pela membrana basal. O folículo permanece conectado ao epitélio germinativo uma vez que ambos compartilham uma porção comum da membrana basal. Células oriundas do estroma circundam o folículo ovariano exceto na região de compartilhamento da membrana basal formando a teca. O folículo, a membrana basal e a teca formam o complexo folicular. O desenvolvimento do oócito ocorre dentro do complexo folicular e compreende os estágios de crescimento primário e secundário, maturação e ovulação. Os alvéolos corticais surgem no ooplasma momentos antes do início do crescimento secundário ou estágio vitelogênico que tem início com a deposição de vitelo, progride até o oócito esteja completamente desenvolvido e o ooplasma preenchido pelos glóbulos de vitelo. A maturação é caracterizada pela migração do núcleo ou vesícula germinativa, pela quebra da vesícula germinativa, ou seja, pela fragmentação do envoltório nuclear e, retomada da meiose. Na ovulação o ovo é liberado do complexo folicular para o lúmen ovariano. em comparação com os Perciformes marinhos com ovos pelágicos, o desenvolvimento oocitário em Gymnotus sylvius tem menos etapas dentro dos estágios de desenvolvimento, sendo as duas mais notáveis delas as ausências da formação das gotas de lipídio durante os crescimentos primário e secundário (e a consequente fusão das gotas para formar um único glóbulo de lipídio durante a maturação) e, a hidrólise do vitelo antecedendo a ovulação.

Strongyloides venezuelensis infection susceptibility of seven inbred strains of mice

Foi investigada a susceptibilidade de sete linhagens isogênicas de camundongos à infecção experimental, primária e secundária, por Strongyloides venezuelensis a fim de servir de base para estudos genéticos sobre a resistência. Foram utilizados 12 camundongos machos, com seis semanas de idade, das seguintes linhagens isogênicas: A/J, BALB/c, CBA/J, C3H/Hepos, C57BL/6, DBA/2 e NIH. Os animais foram inoculados, via sub-cutânea, com 2000 larvas infectantes. As contagens médias (± desvio padrão) de parasitas no intestino delgado dos camundongos seis dias após a infecção, em ordem crescente, foram: 28 (± 19) na linhagem NIH; 647 (± 228) na BALB/c; 709 (± 425) na DBA/2; 731 (± 151) na C3H/Hepos, 801 (± 174) na CBA/J; 1024 (± 267) na C57BL/6 e 1313 (± 483) na A/J. Os camundongos C57BL/6 apresentaram as mais elevadas contagens de ovos de S. venezuelensis por grama de fezes (OPG) e os NIH, as mais baixas. Não foram detectados ovos nos exames de fezes e não foram encontrados parasitas no intestino delgado dos animais re-infectados 14 dias após a infecção primária. A linhagem NIH apresentou elevada resistência contra as infecções primárias por S. venezuelensis. Entre as outras seis linhagens, uma das mais susceptíveis foi a linhagem C57BL/6.
