25. Atributos microbiológicos de um latossolo bruno submetido a diferentes sistemas de manejo e calagem / Soil microbiological atributtes of a brown latosol submitted to different management systems and liming
This work was conducted in Guarapuava, state of Paraná, in a southern brazilian oxisol, in a trial established in 1978. The aim of this work was to analyse the effect of different soil management systems and liming on the microbial biomass and its activity related to C and N in the soil. The managment systems evaluated were: no-tillage with lime incorporate

26. Fauna do solo e outros atributos edáficos como indicadores da qualidade ambiental em áreas com Araucaria angustifolia no Estado de São Paulo / Soil fauna and others edaphics attributes as environmental quality indicators in areas with Araucaria angustifolia in São Paulo State, Brazil
The study of biological soil quality indicators in areas with Araucaria is very important to understand ecological processes in these systems, since groups of the soil fauna are major factors in the decomposition and mineralization of organic matter, as well as modifiers of soil physical, chemical and biological properties and processes. The objective of thi

27. Conversão do Cerrado em pastagem e sistemas agrícolas: efeitos na dinâmica da matéria orgânica do solo / Brazilian savanna conversion to pastures and agricultural systems: effects in the soil organic matter dynamics
A mudança de uso da terra no Cerrado acarreta em alterações na dinâmica da matéria orgânica do solo (MOS). Práticas de manejo com revolvimento das camadas de solo aceleram a decomposição da MOS, favorecendo as emissões de gases do efeito estufa do solo para atmosfera. Dessa forma, o objetivo desse trabalho foi avaliar as mudanças na dinâmica da M

28. Doses de nitrogênio e seu efeito nos indicadores microbiológicos de qualidade de solo na cultura da cevada
The objective of this study was to evaluate the effect of different nitrogen doses and soil depths on microbial biomass carbon and nitrogen in a sandy textured Oxisol, cultivated with barley. The experiment was installed in June, 2004, in an area located at Embrapa Cerrados, Federal District, which had been cultivated with millet for three years and subseque

29. Atividade e diversidade da biomassa microbiana em diferentes sistemas de manejo do solo e de culturas no norte do Estado do Parana / Activity and diversity of microbial biomass under different soil and crop management systems in the north of the state of Parana (Brazil)
The microbial biomass carbon (MB-C) and nitrogen (MB-N), basal respiration and metabolic quotient (qCO2) were evaluated in a Rhodic Eutrudox of the North Region of the State of Paraná under different soil and crop management systems. The experimental area was established in 1988/1989 at the experimental station of Embrapa Soja, Londrina, Paraná, and consis

30. Ecological indicators for the restoration of degraded areas in the Poço das Antas Biological Reserve, Rio de Janeiro State / Indicadores da restauração de áreas degradadas na Reserva Biológica de Poço das Antas,RJ
Mixed plantations of indigenous tree species have been widely used in the restoration of degraded Atlantic forests which had been converted to pastures. This study used ecological indicators to evaluate the status of restoration in mixed plantations at the Poço das Antas Biological Reserve, Southeastern Brazil. Study sites involved mature forests (F), 8-yea

31. Postabsorptive respiratory quotient and insulin-stimulated glucose storage rate in nondiabetic pima indians are related To glycogen synthase fractional activity in cultured myoblasts.
A decreased ratio of fat to carbohydrate oxidation rate (an elevated respiratory quotient) predicts the development of obesity. Skeletal muscle accounts for a major fraction of total body lipid oxidation and is the principle site for reduced glucose storage in insulin-resistant subjects. The potentially important role that muscle has in promoting obesity or

32. DNA variation in the genes of the Na,K-adenosine triphosphatase and its relation with resting metabolic rate, respiratory quotient, and body fat.
The aim of this study was to investigate in 261 subjects from 58 families the association between DNA variation at the genes coding for the Na,K-ATPase peptides and resting metabolic rate (RMR), respiratory quotient (RQ), and percent body fat (%FAT). Five restriction fragment length polymorphisms (RFLP) at three Na,K-ATPase genes were determined: one at the

33. Effects of mutations in the human uncoupling protein 3 gene on the respiratory quotient and fat oxidation in severe obesity and type 2 diabetes.
Human uncoupling protein 3 (UCP3) is a mitochondrial transmembrane carrier that uncouples oxidative ATP phosphorylation. With the capacity to participate in thermogenesis and energy balance, UCP3 is an important obesity candidate gene. A missense polymorphism in exon 3 (V102I) was identified in an obese and diabetic proband. A mutation introducing a stop cod

34. Acute effects of inhaled salbutamol on the metabolic rate of normal subjects.
BACKGROUND--This study was designed to investigate the contribution of inhaled salbutamol to the increase in resting metabolic rate found in patients with chronic airflow limitation who were receiving bronchodilator therapy. METHODS--The resting metabolic rate of 10 normal subjects (age 20-47 years, weight 42-105 kg, seven men) was studied after inhalations

35. Paradoxical resistance to diet-induced obesity in UCP1-deficient mice
The availability of mice lacking the mitochondrial uncoupling protein UCP1, has provided an opportunity to analyze the relationship between the capacity for energy expenditure and the development of obesity in response to a high-fat, high-sucrose diet. Congenic UCP1-deficient mice on a C57BL/6J genetic background show a temperature-dependent resistance to di

36. Intermediate Energy Metabolism of Leptospira
Metabolic studies were performed on three representative serotypes of Leptospira: a water isolate designated B16 and two pathogenic serotypes, pomona and schueffneri. Examination of whole cells of B16 for their ability to oxidize various substrates revealed that oleate significantly stimulated oxygen uptake. The respiratory quotient of 0.7 implied that oleat
