25. Reasons of Atlantic Forest recovery in the state of São Paulo / Determinantes da recuperação da Mata Atlântica no Estado de São Paulo.
Over the last decade, some two hundred municipalities in the state of São Paulo increased the area of Atlantic Forest, and since most of them are adjacent areas they are starting to show up as authentic spots of recovering forests on the map of the State. The present thesis seeks to identify the major factors underpinning this unprecedented increase. The in

26. Streamflow and sediment yield simulation within a small watershed through geoprocessing and modeling techniques. / Simulação de escoamento e de produção de sedimentos em uma microbacia hidrográfica utilizando técnicas de modelagem e geoprocessamento.
Hydrological and water quality models have been developed to evaluate the nonpoint source pollution in agricultural watershed. With this objective, SWAT (Soil and Water Assessment Tool) model was applied to simulate the streamflow and sediment yield in Ribeirão dos Marins watershed, on the Piracicaba river basin, Brazil, for the period 1999/2000. The applic

27. Atividade antiulcerogencia do oleo essencial e da fração rica em alfa-bisabolol, obtidos de especies do genero Eremanthus
The species of the gender Eremanthus, are known popularly as lamps and wood lamps and found in several savannah areas. Your essential oil is very used by the industry of cosmetics, being produced in Brazil and exported for several countries. For being used as cicatrizant by workers involved in your production, this oil was selected for studies of antiulcerog

28. Association between human serum-induced crisis forms in cultured Plasmodium falciparum and clinical immunity to malaria in Sudan.
Clinical histories with regard to falciparum malaria were collected from adults living in holo-, hyper-, and hypoendemic areas of Sudan and matched to serum samples which were assayed for antiparasitic activity in cultures of Plasmodium falciparum. The adult population of the endemic areas could be divided into three groups based on oral histories: those who

29. Global climate change and mammalian species diversity in U.S. national parks
National parks and bioreserves are key conservation tools used to protect species and their habitats within the confines of fixed political boundaries. This inflexibility may be their “Achilles' heel” as conservation tools in the face of emerging global-scale environmental problems such as climate change. Global climate change, brought about by rising le

30. Hybridization rapidly reduces fitness of a native trout in the wild
Human-mediated hybridization is a leading cause of biodiversity loss worldwide. How hybridization affects fitness and what level of hybridization is permissible pose difficult conservation questions with little empirical information to guide policy and management decisions. This is particularly true for salmonids, where widespread introgression among non-nat

31. The federal role in the health information infrastructure: a debate of the pros and cons of government intervention.
Some observers feel that the federal government should play a more active leadership role in educating the medical community and in coordinating and encouraging a more rapid and effective implementation of clinically relevant applications of wide-area networking. Other people argue that the private sector is recognizing the importance of these issues and wil

32. Systemic and mucosal immune responses in mice orally immunized with avirulent Salmonella typhimurium expressing a cloned Porphyromonas gingivalis hemagglutinin.
Porphyromonas gingivalis produces a variety of virulence factors that may have a function in the periodontal disease process. Determination of the role of these various factors in pathogenesis and identification of a means for protecting the host from the destructive effects of this organism are areas of vigorous investigation. In this study we demonstrate t

33. New roles of calsequestrin and triadin in cardiac muscle
Cardiac calsequestrin (Casq2) and triadin are proteins located in specialized areas of the sarcoplasmic reticulum (SR) where the SR forms junctions with the sarcolemma (junctional SR). Casq2, triadin and junctin form a protein complex that is associated with cardiac ryanodine receptor 2 (RyR2) SR Ca2+ release channels. This review highlights new insights of

34. Bicycle accidents in childhood.
The results of a 10 year study of bicycle fatalities and an eight year study of serious non-fatalities are reported for urban Brisbane (population 1,000,000). There were 845 serious non-fatal bicycle accidents and 46 fatalities during the study. Boys were involved in 86% of accidents. Boys have an accident rate of 134.21 per 100,000 population at risk and a

35. Cloning and Sequencing of a Candida albicans Catalase Gene and Effects of Disruption of This Gene†
Catalase plays a key role as an antioxidant, protecting aerobic organisms from the toxic effects of hydrogen peroxide, and in some cases has been postulated to be a virulence factor. To help elucidate the function of catalase in Candida albicans, a single C. albicans-derived catalase gene, designated CAT1, was isolated and cloned. Degenerate PCR primers base

36. Construction, Characterization, and Animal Testing of WRSd1, a Shigella dysenteriae 1 Vaccine
WRSd1 is a Shigella dysenteriae 1 vaccine containing deletions of the virG(icsA) gene required for intercellular spreading and a 20-kb chromosomal region encompassing the Shiga toxin genes (stxAB). WRSd1 was constructed from S. dysenteriae 1 strain 1617 that was originally isolated during the 1968 to 1969 epidemic of Shiga dysentery in Guatemala. The virG(ic
