1. Bilevel positive airway pressure in two moments after bariatric surgery
RESUMO OBJETIVO Investigar o uso da pressão positiva em dois níveis nas vias aéreas (BiPAP) em obesos mórbidos em dois momentos após a cirurgia bariátrica (bypass gástrico em Y-de-Roux): recuperação pós-anestésica (RPA) e primeiro dia de pós-operatório (1PO). DESENHO Ensaio clínico randomizado e cego. MÉTODO Foram estudados 40 obesos mó

2. Correlação da composição corporal com a função pulmonar e com a força muscular respiratória em indivíduos com a Trissomia 21 no Distrito Federal
Introduction: Overweight and respiratory malfunctions are frequently found in Trysomy 21 bearers. Such disturbances are potentially able to lead to conditions which endanger the quality of life of affected individuals, thus aggravating their physical health and excluding them from social interaction. Purpose: the purpose of this academic essay was to investi

3. INFLUENCE OF THE RESPIRATORY FREQUENCY ON THE ARTERIAL GASES SANGUINEOUS IN POSTOPERATIVE THE IMMEDIATE ONE OF EXPLORING LAPAROTOMIA FOR ABDOMINAL TRAUMA / A INFLUÊNCIA DA FREQUÊNCIA RESPIRATÓRIA SOBRE OS GASES SANGUÍNEOS ARTERIAIS NO PÓS - OPERATÓRIO IMEDIATO DE LAPAROTOMIA EXPLORADORA POR TRAUMA ABDOMINAL
The incidence of post-operative pulmonary complications is large, in consequence of the manipulation of abdominal cavity with changes on pulmonary volumes and capacities, resulting in atelectasis and hypoxemy. Alteration of breath pattern in association with postoperative pain can interfere in gaseous exchanges with larger repercussions in the presence of ri

4. InfluÃncia dos nÃveis deimersÃo sobre a funÃÃo pulmonar,a ventilaÃÃo voluntÃria mÃxima e a pressÃo dos mÃsculos respiratÃrios em indivÃduos saudÃveis
As alteraÃÃes da mecÃnica respiratÃria proveniente da imersÃo atà altura do pescoÃo, atravÃs dos efeitos da pressÃo hidrostÃtica e da forÃa de flutuaÃÃo, sÃo pouco estudadas. O objetivo deste estudo foi avaliar em indivÃduos sadios a funÃÃo pulmonar, a ventilaÃÃo voluntÃria mÃxima e a pressÃo dos mÃsculos respiratÃrios durante diferen

5. Aspects of Pulmonary Mechanics in Arc Welders' Siderosis
Sixteen working welders with more than seven years' exposure and a chest radiograph suggestive of siderosis and 13 healthy unexposed men were studied. Each subject had a comprehensive medical and work history, physical examination, standard chest film, and pulmonary function investigation (lung volumes, ventilatory capacities, pulmonary compliance in static

6. Idiopathic pulmonary fibrosis: current understanding of the pathogenesis and the status of treatment
IDIOPATHIC PULMONARY FIBROSIS (IPF) is a progressive and lethal pulmonary fibrotic lung disease. The diagnostic histological changes are called usual interstitial pneumonia and are characterized by histological temporal heterogeneity, whereby normal lung tissue is interspersed with interstitial fibrosis, honeycomb cysts and fibroblast foci. Pulmonary functio

7. Hypoxemia in pulmonary embolism, a clinical study
The cause of hypoxemia was studied in 21 patients with no previous heart or lung disease shortly after an episode of acute pulmonary embolism. The diagnosis was based on pulmonary angiography demonstrating distinct vascular filling defects or “cutoffs.” It was found that virtually all of the hypoxemia in patients with previously normal heart and lungs co

8. Proliferation and differentiation of fetal rat pulmonary epithelium in the absence of mesenchyme.
Previous studies have shown that pulmonary mesenchyme is required to maintain epithelial viability and to support branching morphogenesis and cytodifferentiation. We have examined whether pulmonary mesenchyme can be replaced by a medium containing a combination of soluble factors. Day 13-14 fetal rat distal lung epithelium was enzymatically separated from it

9. Angiopathic consequences of saturating the plasma scavenger system for actin.
Two plasma proteins, vitamin D-binding protein (actin monomer sequestrant) and gelsolin (actin polymer severing), have been found in association with actin in plasma from ill humans and during experimental injury. In vitro, these are the only plasma proteins that display a high affinity for actin. We infused increasing amounts of globular actin intravenously

10. Abnormalities of lung function in hay fever.
Twenty subjects with symptoms of hay fever were studied to see whether abnormalities could be detected in the function of small airways. The investigations included dynamic compliance at varying respiratory frequencies, closing capacity, residual volume, transfer factor, and maximal expiratory flow-volume curves. The tests were repeated in the winter when sy

11. Levels of the Candida metabolite D-arabinitol in sera of steroid-treated and untreated patients with sarcoidosis.
We measured the Candida metabolite D-arabinitol and its enantiomer L-arabinitol in 42 serum samples from 33 patients with sarcoidosis and compared the results with those from 27 healthy adults and 4 patients with candidiasis. The D- and L-arabinitol concentrations and the D- and L-arabinitol/creatinine ratios did not differ significantly in the sarcoidosis p

12. Increasing metastatic potential is associated with increasing genetic instability of clones isolated from murine neoplasms.
The metastatic stability of clones, which were derived from the murine UV-2237 fibrosarcoma and which exhibit low or high metastatic potential, was examined after 60-72 days of continuous growth in vitro and in vivo. Subclones of the high metastatic clone exhibited a 140-fold variation in the production of experimental pulmonary metastases after intravenous
