1. Total antibiotic use in a state-wide area and resistance patterns in Brazilian hospitals: an ecologic study
ABSTRACT Introduction: Use of antibiotic and bacterial resistance is the result of a complex interaction not completely understood. Objectives: To evaluate the impact of entire antimicrobial use (community plus hospitals) on the incidence of bloodstream infections in intensive care units adjusted by socioeconomic factors, quality of healthcare, and access

2. Competition Indexes to Evaluate Tree Growth in a Semi-Deciduous Seasonal Forest
RESUMO A maioria dos estudos que analisa o comportamento da competição arbórea é voltada para plantios homogêneos e equiâneos. Nota-se, portanto, uma carência de informações deste tipo em florestas naturais de elevada biodiversidade. Objetivou-se com este trabalho avaliar a competição em um fragmento de Floresta Estacional Semidecidual, por grupo

3. Evaluation of the environmental sustainability of massive forestry fragments of the coastal plain and lower slopes of Bertioga (SP) / Avaliação da sustentabilidade ambiental dos fragmentos de maciços florestais da planície costeira e baixa encosta do município de Bertioga (SP)
The São Paulo coastal zone alternates extensive zones of great diversity of biotopes with others intensively degradated. These characteristics are observed in the municipality of Bertioga and its forest regions localized among Itaguaré and Guaratuba river basins. Due to their special characteristics these basins are denominated Bertioga System. The aim of

4. Liming effects on growth of native woody species from brazilian savannah.
The liming effects on the fifteen woody species from Cerrado region (the Brazilian savannah) were evaluated under glasshouse conditions. The species used belong to different ecologic groups, namely: pioneer, secondary and climax trees. The soil treatment consisted in the absence of liming (-LIM) and liming sufficient to reach soil pH 6.0 (+LIM). In general,

5. Crscimento inicial de especies florestais de diferentes grupos sucessionais em resposta a doses de fosforo.
Objetivando avaliar a resposta de especies florestais ao fornecimento de P, conduziu-se um ensaio sob condicoes de casa de vegetacao, cultivando-se mudas das especies arboreas pioneiras (aroeira - Lithraea molleoides; aroeirinha - Schinus terebinthifolius; jacare - Piptadenia gonoacantha; sabia - Mimosa caesalpiniaefolia; sesbania - Sesbania virgata), climax

6. Postprandial thermogenesis in Bothrops moojeni (Serpentes: Viperidae)
Snakes that can ingest prey that are proportionally large have high metabolic rates during digestion. This great increase in metabolic rate (specific dynamic action - SDA) may create a significant augment in the animal's body temperature. The present study investigated postprandial thermogenesis in Bothrops moojeni. Briefly, two groups of snakes were fed mea

7. Os grupos tróficos em Coleoptera
The beetles are a useful group for studies on trophic structure of communities, mainly in forested areas. These kind of studies are based on food habits of species groups. The different terms applied to nomminated these groups (trophic category, ecologic group, trophic group, guild, trophic guild) are discussed. The term trophic group, a natural unity, is pr

8. Ecologic Genomics of DNA: Upstream Bending in Prokaryotic Promoters
After our analysis of the distribution of predicted intrinsic curvature along all available complete prokaryotic genomes, the genomes were divided into two groups. Curvature distribution in all prokaryotes of the first group indicated a substantial fraction of promoters characterized by intrinsic DNA curvature located within or upstream of the promoter regio

9. Interaction of Clostridium difficile and Escherichia coli with microfloras in continuous-flow cultures and gnotobiotic mice.
We studied the interactions between the entire cecal flora of hamsters and the pathogens Clostridium difficile and Escherichia coli in gnotobiotic mice and in a continuous-flow (CF) culture system in which the growth medium consisted of an extract of fecal pellets from germfree mice. CF cultures and germfree mice were colonized first with C. difficile and E.

10. Associations among hospital capacity, utilization, and mortality of US Medicare beneficiaries, controlling for sociodemographic factors.
OBJECTIVE: To explore whether geographic variations in Medicare hospital utilization rates are due to differences in local hospital capacity, after controlling for socioeconomic status and disease burden, and to determine whether greater hospital capacity is associated with lower Medicare mortality rates. DATA SOURCES/STUDY SETTING: The study population: a 2
