37. pH in exhaled breath condensate and nasal lavage as a biomarker of air pollution-related inflammation in street traffic-controllers and office-workers
OBJECTIVE: To utilize low-cost and simple methods to assess airway and lung inflammation biomarkers related to air pollution. METHODS: A total of 87 male, non-smoking, healthy subjects working as street traffic-controllers or office-workers were examined to determine carbon monoxide in exhaled breath and to measure the pH in nasal lavage fluid and exhaled

38. Is there an association between postural balance and pulmonary function in adults with asthma?
OBJECTIVE: Asthma may cause systemic repercussions due to its severity and the effects of treatment. Our objective was to compare posture, balance, functional capacity, and quality of life (QOL) according to the severity of disease, as assessed by pulmonary function levels. METHOD: This cross-sectional study evaluated fifty individuals with asthma. We com

39. Relationship between body balance, lung function, nutritional status and functional capacity in adults with cystic fibrosis
BACKGROUND: Cystic fibrosis (CF) is a hereditary condition in which lung disease affects all patients. In addition to pulmonary involvement, the multisystemic components of CF cause significant physical limitations. However, the impact of lung function on balance control in CF has not been studied. OBJECTIVE: To assess body balance in adults with CF an

40. Mapping and signaling of neural pathways involved in the regulation of hydromineral homeostasis
Several forebrain and brainstem neurochemical circuitries interact with peripheral neural and humoral signals to collaboratively maintain both the volume and osmolality of extracellular fluids. Although much progress has been made over the past decades in the understanding of complex mechanisms underlying neuroendocrine control of hydromineral homeostasis, s

41. Avaliação do ciclo de vida da areia em mineradora de pequeno porte, na região de São José do Rio Preto - SP / Life Cycle Assessment of sand in small mining in São José do Rio Preto region - São Paulo.
The mining of sand, although of great socio-economic importance to the national scene, has several negative impacts throughout the production chain. Among some of the interference in the natural environment occurs, soil degradation, air pollution and stress in the fauna and flora. This fact has generated great interest in mechanisms that mitigate or prevent

43. Vascular dysfunction by myofibroblast activation in patients with idiopathic pulmonary fibrosis and prognostic significance
In this study, we demonstrated the importance of telomerase protein expression and determined the relationships among telomerase, endothelin-1 (ET-1) and myofibroblasts during early and late remodeling of parenchymal and vascular areas in usual interstitial pneumonia (UIP) using 27 surgical lung biopsies from patients with idiopathic pulmonary fibrosis (IPF)

44. Emission factor of single pellet cake seed Jatropha curcas in a fix bed reactor
The objective of this study is to evaluate the emission factor of oil cake seed Jatropha curcas that was formed into pellets with three parameters: pyrolisis, densification and air flow rate. The effect of pyrolisis was investigated using four samples of pellet: nonpyrolysis pellet, 90 minutes pyrolysis pellet, 120 minutes pyrolysis pellet, 150 minutes pyrol

45. Cardiopulmonary exercise testing variables as predictors of long-term outcome in thoracic sarcoidosis
Cardiopulmonary exercise testing (CPET) plays an important role in the assessment of functional capacity in patients with interstitial lung disease. The aim of this study was to identify CPET measures that might be helpful in predicting the vital capacity and diffusion capacity outcomes of patients with thoracic sarcoidosis. A longitudinal study was conducte

47. Desenvolvimento de novos sistemas de eletrocatalisadores nano-dispersos 20%Pt-(2% Pt-Ce0,9W0,102)/C tolerantes ao monóxido de carbono( CO) para ânodos de PEMFC / Development of new systems of nano-disperse 20%Pt-(2%Pt-Ce0,9W0,1O2)/C electrocatalysts tolerant to carbon monoxide (CO) for PEMFCs anodes
O material (pó) de nanofase de Ce0,9W0,1O2 foi sintetizado por coprecipitação de oxalatos de cério (IV) e cátions de tungstênio (IV). A redução da platina (2%) foi feita pelo método da redução por álcool, utilizando uma solução de ácido hexacloroplatínico (H2PtCl6.6H2O) como fonte do metal, óxido de cério dopado com tungstênio (Ce0,9W0,1O2
