1. Inflammatory and oxidative stress airway markers in premature newborns of hypertensive mothers
Although oxidative stress and inflammation are important mechanisms in the pathophysiology of preeclampsia and preterm diseases, their contribution to the respiratory prognosis of premature infants of hypertensive mothers is not known. Our objective was to determine the levels of oxidative stress and inflammation markers in the airways of premature infants b

2. Yoga for asthma
ABSTRACT BACKGROUND: Asthma is a common chronic inflammatory disorder affecting about 300 million people worldwide. As a holistic therapy, yoga has the potential to relieve both the physical and psychological suffering of people with asthma, and its popularity has expanded globally. A number of clinical trials have been carried out to evaluate the effects

3. Assessment of the mechanics of a tissue-engineered rat trachea in an image-processing environment
OBJECTIVES:Despite the recent success regarding the transplantation of tissue-engineered airways, the mechanical properties of these grafts are not well understood. Mechanical assessment of a tissue-engineered airway graft before implantation may be used in the future as a predictor of function. The aim of this preliminary work was to develop a noninvasive i

4. Phase I clinical trial of cell therapy in patients with advanced chronic obstructive pulmonary disease: follow-up of up to 3 years
BACKGROUND Chronic obstructive pulmonary disease is a major inflammatory disease of the airways and an enormous therapeutic challenge. Within the spectrum of chronic obstructive pulmonary disease, pulmonary emphysema is characterized by the destruction of the alveolar walls with an increase in the air spaces distal to the terminal bronchioles but without si

5. Envolvimento das pequenas vias aéreas na Síndrome do Desconforto Respiratório Agudo: papel da inflamação, das alterações do surfactante e da apoptose de células epiteliais / Expression of acute phase cytokines, surfactant proteins, and epithelial apoptosis in small airways of human ARDS
Alguns estudos sugerem que as pequenas vias aéreas têm um papel importante na fisiopatologia da lesão pulmonar aguda/ síndrome do desconforto respiratório agudo (LPA/SDRA). O epitélio respiratório que reveste as vias aéreas é capaz de liberar mediadores inflamatórios e está relacionado ainda com a produção de surfactante nas vias aéreas. Até o

6. Dimensões das vias aéreas na asma fatal e na doença pulmonar obstrutiva grave / Airway dimensions in fatal asthma and severe COPD
Background: In some patients with chronic asthma, clinical and physiological similarities with chronic obstructive pulmonary disease may co-exist, such as partial reversibility to bronchodilators despite persistent expiratory airflow obstruction. However, pathologic analyses comparing both diseases in patients of similar age and disease severity are scarce.

7. Influência do montelucaste sobre o estado de ativação dos eosinófilos e função dos fagócitos em crianças asmáticas
Asthma is one of the most common chronic diseases in childhood and its prevalence and severity are increasing in many parts of the world in recent years. The main characteristic of asthma is inflammation of the lower airways, responsible for bronchial hyperresponsiveness and variable airflow limitation, reversible with or without treatment. Several cells pla

8. Componentes da matriz extracelular e seus reguladores no músculo liso brônquico na asma / Extracellular matrix components and regulators in the airway smooth muscle in asthma
There is an intimate relationship between the extracellular matrix (ECM) and smooth muscle cells within the airways. Few studies have comprehensively assessed the composition of different ECM components and its regulators within the airway smooth muscle (ASM) in asthma. With the aid of image analysis, the fractional area of total collagen and elastic fibres

9. Remodelamento das pequenas vias aéreas nas pneumonias intersticiais idiopáticas / Aspects of psychosexuality and personality of maleto- female and female-to-male transsexuals evaluated by Szondi projetive test
Introdução: Poucos estudos têm sido direcionados às mudanças histopatológicas nas pequenas vias áreas e seu possível papel no processo de remodelamento, nas pneumonias intersticiais idiopáticas. Objetivos: Estudar aspectos morfológicos, morfométricos e de imunohistoquímica das pequenas via aéreas na Fibrose Pulmonar Idiopática/ Pneumonia Inters

10. Condição periodontal de indivíduos submetidos à radioterapia associada ou não à quimioterapia das vias aerodigestivas superiores: um estudo prospectivo
Studies have investigated the progression of periodontal disease in patients undergoing radiotherapy, as part of the treatment of malignant tumors of the upper airways (mainly in tumors of the mouth). They showed increased periodontal attachment loss, which can be explained by a combination of factors as the direct action of radiation on tissues, accumulatio

11. Effects of the exposure to cigarette smoke and residual oil fly ash (ROFA) in lungs of C57/Bl6 mice / Efeito da exposição à fumaça de cigarro e ao resíduo de óleo diesel (ROFA) em pulmões de camundongos C57/BI6
Many of the mechanisms leading to CPOD (Chronic Pulmonary Obstructive Disease) are not completely understood. In the present study, we exposed C57/Bl6 mice, for two months, to cigarette smoke and/or ROFA (Residual Oil Fly Ash). Animals exposed to cigarette smoke had an increased in proximal airways resistance, probably due to the thickening of airways walls

12. Evaluation of the mechanics of the respiratory system using PV curves in patients with idiopathic pulmonary fibrosis / Avaliação da mecânica do sistema respiratório através da obtenção de curva PV em pacientes com pneumonia intersticial idiopática
The objective of this study was to evaluate small airways compromise in Idiopathic Pulmonary Fibrosis (IPF) using pressure-volume (PV) curves of the respiratory system. We collected PV curves from twelve patients before lung biopsy, which confirmed IPF in seven patients and Hipersensitivity Pneumonia in five. All curves were fitted with a sigmoid model, V =
