13. InvestigaÃÃo citogenÃtica do potencial alelopÃtico de espÃcies de lÃquens e pteridÃfitas / Cytogenetic investigation of the allelopathic potential of lichens and pteridophytas species.
The allelopathic potential of two species of lichens (Myelochroa lindmanii and Canoparmelia texana) and two species of pteridophytas(Gleicheniella pectinata and Dicranopteris flexuosa) was evaluated by the effects of its aqueous extracts on germination, root growth and cytogenetic analysis in seeds of lettuce (Lactuca sativa) and maize (Zea mays). The extrac

14. SÃrie temporal do fitoplÃncton no estuÃrio de Barra das Jangadas (JaboatÃo dos Guararapes-Pernambuco-Brasil)
The Barra das Jangadas (PE-Brazil) estuarine system, located at the South of Recife City, have been in the last years under strong anthropic impacts. This estuarine system was studied to assess the phytoplankton temporal dynamics and to obtain the main environmental factors affecting the area. Sampling was carried out in one fixed station during a temporal s

15. Importancia ecofisiologica da reserva de xiloglucano e o controle de sua mobilização em cotiledones de Hymenaea courbaril L
Hymenaea courbarí/ is a climax leguminous tree species considered to be shade tolerant with wide neotropical geographic distribution. Seed cotyledons are rich in xyloglucan (XG), which is the main carbon reserve for the seedling growth. This polymer is a cell wall polysaccharide and its mobilisation mechanism, based on the co-ordinated action of four enzyme

16. Construção, calibração e análise de funcionamento de lisímetros de pesagem para determinação da evapotranspiração da cultura da lima ácida Tahiti (Citrus latifolia Tan.). / Construction, calibration and analysis of the operation of a weighing lysimeter to determine the evapotranspiration of "tahiti" lime (citrus latifolia tan.).
This study had as main objectives a) the construction, calibration and operation of load cell based weighing lysimeters to measure the water consumption of orchard trees in situ; b) the evapotranspiration measurement at the first stages after plantation of a "Tahiti" lime (Citrus latifolia Tan.) orchard; and c) the crop coefficient (Kc) determination for the

17. "Validação de um novo método de isolamento de vírus rábico - prevalência do vírus rábico em morcegos albergados no parque estadual intevales, estado de São Paulo: estudo comparativo entre duas metodologias" / Prevalence study of the rabies virus in bats lodged in the rain forest: a comparative study of two methodologies
O estudo de prevalência do vírus rábico foi realizado em uma amostra de morcegos capturados na Mata Atlântica da região sudeste do Brasil. Os morcegos são um dos principais reservatórios silvestres do vírus rábico. No Brasil existem aproximadamente 144 espécies de morcegos, e pouco se sabe sobre a circulação do vírus rábicos nessas espécies. F

18. CONTRIBUIÇÃO AO ESTUDO DO ESPALHAMENTO POR CHUVAS / CONTRIBUTION TO THE STUDY OF RAIN SCATTERING
The purpose of this work is to present a mathematical model which interprets the scattering caused by pluviometric precipitation in tropospheric propagation. Concerning pratical applications, our main interest was to analyze the interference between a satellite system Earth station and a terrestrial cell whose diameter depends upon local and punctual precipi

19. The Loss of Ribulose-1,5-Bisphosphate Carboxylase/Oxygenase Caused by 24-Hour Rain Treatment Fully Explains the Decrease in the Photosynthetic Rate in Bean Leaves.
Recently, we have found that simulated rainfall causes a chronic inhibition of leaf photosynthesis in Phaseolus vulgaris (M. Ishibashi and I. Terashima [1995] Plant Cell Environ 18: 431-438). Mechanisms of this inhibition were examined in the present study. After the plants were treated with continuous mist for 24 h and then dried to unwet conditions, light-

20. The Control of Storage Xyloglucan Mobilization in Cotyledons of Hymenaea courbaril1
Hymenaea courbaril is a leguminous tree species from the neotropical rain forests. Its cotyledons are largely enriched with a storage cell wall polysaccharide (xyloglucan). Studies of cell wall storage polymers have been focused mostly on the mechanisms of their disassembly, whereas the control of their mobilization and the relationship between their metabol

21. An epidemic of tuberculosis with a high rate of tuberculin anergy among a population previously unexposed to tuberculosis, the Yanomami Indians of the Brazilian Amazon
A survey of an emerging tuberculosis epidemic among the Yanomami Indians of the Amazonian rain forest provided a unique opportunity to study the impact of tuberculosis on a population isolated from contact with the tubercle bacillus for millennia until the mid-1960s. Within the Yanomami population, an extraordinary high prevalence of active tuberculosis (6.4

22. Complete Sequence of a Novel Highly Divergent Simian T-Cell Lymphotropic Virus from Wild-Caught Red-Capped Mangabeys (Cercocebus torquatus) from Cameroon: a New Primate T-Lymphotropic Virus Type 3 Subtype
Among 65 samples obtained from a primate rescue center located in Cameroon, two female adult red-capped mangabeys (Cercocebus torquatus) (CTO-602 and CTO-604), of wild-caught origin, had a peculiar human T-cell lymphotropic virus type 2 (HTLV-2)-like Western blot seroreactivity (p24, RGD21, +/-K55). Analyses of the simian T-cell lymphotropic virus type 3 (ST

23. Simian T-Cell Leukemia Virus (STLV) Infection in Wild Primate Populations in Cameroon: Evidence for Dual STLV Type 1 and Type 3 Infection in Agile Mangabeys (Cercocebus agilis)
Three types of human T-cell leukemia virus (HTLV)-simian T-cell leukemia virus (STLV) (collectively called primate T-cell leukemia viruses [PTLVs]) have been characterized, with evidence for zoonotic origin from primates for HTLV type 1 (HTLV-1) and HTLV-2 in Africa. To assess human exposure to STLVs in western Central Africa, we screened for STLV infection
