BACKGROUND Pneumonia is a major cause of morbidity and mortality in immunocompromised patients. Bronchoalveolar lavage (BAL) is commonly used to help diagnose and characterize pneumonia in these patients. Mini-BAL is a less-invasive, less-costly and less-cumbersome diagnostic tool than BAL. OBJECTIVES In this study, we compared the diagnostic value of BAL and mini-BAL in the evaluation of pne...

This work presents the results of a Chandra study of 21 broad absorption line (BAL) radio-loud quasars (RLQs). We conducted a Chandra snapshot survey of 12 bright BAL RLQs selected from SDSS/FIRST data and possessing a wide range of radio and C IV absorption properties. Optical spectra were obtained nearly contemporaneously with the Hobby-Eberly Telescope; no strong flux or BAL variability was ...

INTRODUCTION Distal airway secretions can be sampled by bronchoscopic bronchoalveolar lavage (B-BAL), blind protected BAL (BP-BAL), and tracheal aspiration (TA). We quantitatively compared the cultures of distal airway secretions from BP-BAL, B-BAL, and TA specimens, and assessed the efficacy of the three above methods in diagnosing bronchitis in tracheostomized children. METHODS Twenty child...

BAL QSOs are notoriously faint X-ray sources, presumably due to extreme intrinsic absorption. However, several objects have begun to appear through the obscuration with recent X-ray observations by Chandra and ASCA. Where enough counts are present for X-ray spectroscopy, the signatures of absorption are clear. The evidence is also mounting that the absorbers are more complicated than previous s...

results in total, 261 patients (119 sarcoidosis and 142 non-sarcoidosis ilds) were enrolled. the median (interquartile range) bal cd4/cd8 ratio and lymphocyte fraction were significantly higher in sarcoidosis than in non-sarcoidosis ilds: 3.88 (3.76) versus 0.88 (1.01), respectively, and 20.6 (28.3) versus 6.0 (13.7), respectively. t cell receptor γ delta, cd16+56+, cd103+, cd8+103+, and cd3+16...

Bu çalışmada, bal arısı kovanı ürünlerinden olan bal, arı ekmeği, poleni ve erkek larvası (apilarnil)'in toplam fenolik (TPC) flavonoid (TFC) profilleri ortaya konuldu. Bunun yanı sıra söz konusu örneklerin antioksidan aktiviteleri, 2,2′-azinobis (3-ethylbenzothiazolin)-6-sulfphonate (ABTS) assay ferric reducing antioxidant power (FRAP) 1,1-diphenyl-2-picrylhydrazy (DPPH) metotları kullanılarak...
