    Multiple linear regression analysis using all variables as factors (Model 1) demonstrated that weight, BMI, and tidal volume were independently associated with the bilateral excursion of the diaphragms (all P < 0.05) after adjusting for other clinical variables, including age, gender, smoking history, height, VC, %VC, FEV1, FEV1%, and %FEV1. There…[Read more]

    We found that higher BMI and higher tidal volume were independently associated with the increased excursions of the bilateral histone methyltransferase by both univariate and multivariate analyses, although the strength of these associations was weak. We cannot explain the exact reason for the correlation between BMI and the excursion of the…[Read more]

    Several older reports in the literature [16] ;  [31] have shown that these satellites (due to charge transfer from the ligand oxygen–uranium bonding band (of enolase oxygen 2p character) to the empty 5f level) can be observed as unique “signatures” for the oxidation and species chemical state in uranium and its compounds. Allen [22] has…[Read more]

    Our study demonstrated that the average excursions of the bilateral CGP-41251 during tidal breathing (right: 11.0 mm, 95% CI 10.4 to 11.6 mm; left: 14.9 mm, 95% CI 14.2 to 15.5 mm) were numerically less than those during forced breathing in previous studies using other modalities 2; 7 ;  8. Using fluoroscopy, Alexander reported that the average…[Read more]
