To address the role of the parietal pleura in reduction of mesothelial shear stresses during breathing, we measured the stiffness of the parietal pleural surface of mammalian chest walls using microindentation. The pleural surface was indented over ribs and intercostal spaces with rigid flat punches (tip radii of 0.01, 0.02, and 0.1 cm) to probe stiffness at length scales comparable with those ...

Some recent work, no tab ly tha t of Dixon and Elliott , 1 has indicated tha t not all cells and tissues are complete ly cyanide-sensit ive in the sense tha t they reduce their ra te of respiration in the presence of cyanides. Alien ~ has pointed out tha t not all the resp i ra tory exchange in Planaria m a y be inhibited b y cyanides. This has indicated tha t there m a y be other oxidation sys...

The Mycobacterium terrae complex, consisting of three saprophytic species, (M. terrae, M. nonchromogenicum, and M. triviale), they rarely cause diseases in immunocompetent people. There are few case reports of lung involvement by Mycobacterium terrae complex. We reported a 13 years old immunompetent girl with a cavitary opacity seen on chest imaging and bronchoscopy revealed an endobronchial le...

Exercise Physiol. 44ftik 931-938, 1978. -Ten patients with daytime somnolence and obesity were found to have periodic airway occlusion (AO) during nocturnal sleep. The cyclical ventilatory pattern consisted of a series of regular inspiratory...

Environ Exercise Physiol. 446): 679682, 1978. -Previous studies of lung volumes during immersion have utilized dilution techniques for residual volume. We have compared lung volumes obtained by the use of a dual inert...

Mucosa associated lymphoid tissue lymphoma (MALToma) of the lung is a rare, low-grade B-cell lymphoma arising from the bronchus associated lymphoid tissue (BALT), usually requiring surgical biopsy using thoracoscopy for diagnosis. We present a case of MALToma of the lung diagnosed with a transbronchial lung biopsy (TBLB) specimen. A 63 year old man presented with hemoptysis. Chest X ray disclos...

We have studied the effect of 3,5,3 't r i iodothyronine (Ts) on the respiration of adul t rat hepatocytes in pr imary monolayer culture p repared f rom hypothyroid rat liver. After addit ion of T3 to the culture medium at a concentration of 2 x 10 -7 M, oxygen consumption of the cultured cells increased detectably at 24 h and was maximal at 72-96 h, relative to control cultures (38.0 -+ 1.8 vs...

In an earlier paper (Y. Yamamura et al., Am. Rev. Respirat. Diseases 91:839, 1965; I. Azuma et al., Am. Rev. Respirat. Diseases, in press), we reported the isolation and purification of a polysaccharide from a culture filtrate of human tubercle bacilli Aoyama B strain. The polysaccharide was shown to have anaphylactic activity in guinea pigs which were sensitized by heatkilled tubercle bacilli....

Respiration in frost-damaged wheat has been observed by us1 to be at a higher level than in normal or sound wheat of the same moisture content. This was believed to be due, in part at least, to the higher percentage of dextrose and other simple carbohydrates in the frozen wheat. It then appeared desirable to determine the effect of sprouting upon the respirat,ion of the grain, to ascertain whet...
