Acta Scientiarum : Animal Sciences , 2006,
Abstract: O presente experimento foi realizado em florada de laranja (Citrus sinensis L. Osbeck), variedade Pera-Rio, com os objetivos de estudar os insetos visitantes nas flores d e laranjeira, o seu comportamento nas flores, o tipo de coleta efetuada e o efeito dessas visitas na produ o de frutos, em quantidade e qualidade. Os dados de freqüência foram obtidos por contagem nos primeiros 10 minutos de cada horário, das 8h às 18h, em três dias distintos, percorrendo-se as linhas da cultura. O comportamento forrageiro de cada espécie de inseto foi avaliado através de observa es visuais, no decorrer do dia, no período experimental. Os insetos observados foram abelhas africanizadas Apis mellifera, Trigona spinipes e Tetragonisca angustula. As abelhas A. mellifera foram os visitantes florais maisfreqüentes e preferiram coletar néctar comparado ao pólen. Os bot es florais descobertos produziram mais frutos que os bot es florais cobertos. Os frutos decorrentes do tratamento coberto foram menores, mais ácidos e com menor quantidade de vitamina C que os frutos do tratamento descoberto. The present experiment was carried out in flowerage of sweet orange(Citrus sinensis L. Osbeck), Pera-rio variety, to study the insects involv ed in pollination, their behaviour in the flower (nectar or pollen collection) and the effect of the pollination on fruit production (quantity and quality). More frequent insects were recorded daily (counted during ten minutes, every hour) from 8:00 a.m. to 6:00 p.m., with three replications. The forage behaviour and nectar and/or pollen collect was also observed. The insect visitors onflowers were Africanized honey bee Apis mellifera, followed by stingless bees Trigona spinipes and Tetragonisca angustula. A. mellifera were the most frequent visitors and preferred to collectnectar than pollen. The uncovered flowers -buds produced more fruits than the covered ones. Another observation was that fruits derived from covered treatment were smaller, more acid and with less quantity of vitamin C than the uncovered ones.

Abstract: in alentejo region low temperatures and soil waterlogging during autumn- winter season are limiting factors for vegetable production under field conditions. short -day onions can be an option to surpass these restrictions. the aim of the present work was to evaluate the effect of short - day onion cultivars and band placement of the fertilizer on onion production in alentejo, planted during the autumn. the experiment was carried out at mitra research station of the university of évora and the treatments were: short - day onion cultivars (?spring star? and ?mineutaka?) and fertilizer application method at plantation (broadcasting and banding at 10 cm ± 2 depth, under the crop row). fertilizer banding did not affect root density (cm cm-3) under the crop row, nor onion bulb yield which was 8.3 and 9.0 kg m-2 for ?spring star? and ?mineutaka? respectively. since the studied cultivars presented resistance to waterlogging and low temperature that occurred during the growing season with good production, short - day onion has great agronomical potential for alentejo region. additionally, having in consideration the growing season conditions, water will not be a limiting factor.

Abstract: As baixas temperaturas e o fácil encharcamento da maioria dos solos do Alentejo constituem uma restri o à produ o de hortícolas ao ar livre, no Outono-Inverno. A cebola de dias curtos pode constituir uma op o pela sua capacidade para superar estes constrangimentos. Assim, este trabalho teve como objectivo estudar o comportamento de duas cultivares de cebola de dias curtos, plantadas no Outono e a influência da localiza o da aduba o aquando da planta o. O ensaio decorreu na herdade experimental da Mitra da Universidade de évora e os tratamentos em estudo foram: a cultivar de cebola de dias curtos (“Spring Star” e “Mineutaka”) e o método de aplica o do adubo à planta o (distribui o a lan o e localiza o do adubo numa faixa a 10 cm ± 2 de profundidade, sob a linha de cultura). A aduba o localizada n o afectou a densidade radical (cm cm-3) sob a linha de cultura, nem a produ o comercial de bolbos a qual foi respectivamente para a “Spring Star” e “Mineutaka” de 8,3 e 9,0 kg m-2. Visto as cultivares estudadas terem apresentado resistência ao excesso de água e às baixas temperaturas que ocorreram durante o ciclo, com produ es consideráveis, a cebola de dias curtos apresenta-se como uma cultura com elevado potencial agronómico para o Alentejo. Adicionalmente, dada a época em que é realizada a cultura a água para a rega n o será um factor limitante. In Alentejo region low temperatures and soil waterlogging during Autumn- Winter season are limiting factors for vegetable production under field conditions. Short -day onions can be an option to surpass these restrictions. The aim of the present work was to evaluate the effect of short - day onion cultivars and band placement of the fertilizer on onion production in Alentejo, planted during the autumn. The experiment was carried out at Mitra Research Station of the University of évora and the treatments were: short - day onion cultivars (“Spring Star” and “Mineutaka”) and fertilizer application method at plantation (broadcasting and banding at 10 cm ± 2 depth, under the crop row). Fertilizer banding did not affect root density (cm cm-3) under the crop row, nor onion bulb yield which was 8.3 and 9.0 kg m-2 for “Spring Star” and “Mineutaka” respectively. Since the studied cultivars presented resistance to waterlogging and low temperature that occurred during the growing season with good production, short - day onion has great agronomical potential for Alentejo region. Additionally, having in consideration the growing season conditions, water will not be a limiting factor.

Abstract: Este trabalho teve como objectivo estudar a influência da aplica o de diferentes quantidades de azoto, repartidas por quatro aplica es, na disponibilidade de azoto nítrico no solo, no comprimento radical, na concentra o de azoto nas folhas e na produ o comercial de cebola de dias médios (cv. Gilmar) no Alentejo. O ensaio decorreu na Centro de estudos e experimenta o da Mitra da Universidade de évora e foi delineado em blocos casualizados com quatro repeti es. Os tratamentos consistiram em 4 níveis de aduba o azotada (0, 37, 74 e 111 kg N ha-1), repartidos por quatro aplica es. A disponibilidade de azoto nítrico no solo, o comprimento radical e a concentra o de azoto nas folhas foram avaliados aos 33, 57, 96 e 127 dias após a planta o. A densidade radical (cm cm-3) sob o bolbo e a 4 cm da linha de cultura, nas diferentes datas e profundidades de amostragem, n o foi afectada pelos níveis de azoto. Ao longo ciclo, 65 a 100 % das raízes, em termos de comprimento radical, concentraram-se sob o bolbo e a densidade radical máxima alcan ada foi de 1,88 cm cm-3. A profundidade máxima de enraizamento situou-se entre os 20 e 30 cm, n o ultrapassando os 10 cm de profundidade até aos 32 dias após a planta o. Nas condi es do ensaio, os resultados indicam como recomendável uma aplica o de 30 kg ha- 1 de azoto à planta o e um aumento da quantidade de azoto aplicado (16,2% do total de N aplicado), no início da forma o do bolbo. A produ o comercial aumentou com o nível de azoto, mas as produ es obtidas com a aplica o de 74 kg ha-1 (5,12 kg m-2) e de 111 Kg N ha-1 (6,59 kg m-2) n o diferiram significativamente. Intermediate-day onions (cv. Gilmar) rooting patterns, soil availability NO3-, leaf N concentration and commercial yield were evaluated in a field trial where four nitrogen fertilizer rates (0, 37, 74 and 111 kg N ha-1) were applied into four split applications, following a randomized block design with four replications. Root length, soil availability NO3-, and leaf N concentration were evaluated at four dates during growing season (33, 57, 96 and 127 days after planting). Root length density (cm cm-3) at different sampling dates, locations (under the bulb and at 4 cm from the plant row) and depths was not affected by nitrogen level. For all sampling dates about 65 to 100 % of the root length was concentrated in the top 10 cm of the soil profile, under the bulb and the maximum root length density was 1.88 cm cm-3.

Human chronic chagasic cardiopathy: participation of parasite antigens, subsets of lymphocytes, cytokines and microvascular abnormalities
Higuchi, Maria de Lourdes;
Memórias do Instituto Oswaldo Cruz , 1999, DOI: 10.1590/S0074-02761999000700044
Abstract: this article tries to demonstrate by new pathological findings (with the use of immunohistochemical technique and confocal laser microscopy) that chronic chagasic cardiomyopathy is a result of multiple factors involving myocarditis, immunodepression, severe fibrosis and microvessels dilatation and that all of these alterations are probably directly related with the presence of trypanosoma cruzi parasites in the host associated with inadequate immunological response of the host.
Gênero e desejo: a inteligência estraga a mulher?
Borges, Maria de Lourdes;
Revista Estudos Feministas , 2005, DOI: 10.1590/S0104-026X2005000300012
Abstract: in this paper i analyze the idea that intelligence is a male erotic attribute, while beauty is what makes woman attractive. i begin by immanuel kant, an 18th century philosopher, according to whom an intelligent woman may have the admiration of men, but not their desire. more than that, an intelligent, yet beautiful woman would lose her power over men, because intelligence can ruin woman attractiveness. i show that this apparently old vision is still alive today. many authors nowadays support the view that what makes a woman's attractive for man is beauty, intelligence being negative or indifferent for attraction. some even assign this idea to a natural essence of man and woman. i will challenge this view, showing that beauty has a cultural aspect and that we cannot appeal to a non-historical essence of human being.

Higuchi, Maria de Lourdes;
Sao Paulo Medical Journal , 1995, DOI: 10.1590/S1516-31801995000200013
Abstract: endomyocardial biopsy procedure has been performed in many centers around the world, allowing a better treatment and follow up of the patients with myocardial disease. in chagas' disease, it has been performed in s?o paulo heart institute since 1978 and has brought important contributions to the understanding of the disease and consequently of the patient's clinical stage. in the present work we summarize the principal findings regarding the pathogenesis of chagas' disease obtained mainly from the studies using endomyocardial biopsy specimens. nowadays we do not have doubts that the inflammatory infiltrate aggressing myocardial fibers has fundamental role in the progression of the myocardial damage in chagas' disease what culminates in chronic heart failure. the parasite seems to have active participation in the maintenance of such myocardial inflammation.
