The Xpert assay on bronchoscopy specimens provided an accurate diagnosis of PTB in patients who had a negative AFB smear or who could not produce sputum.

We present the aperture synthesis imaging of and HCO`1È0 lines and of continuum C 3 H 2 2 12 È1 01 emission at j \ 3.4 mm toward the class 0 young stellar object IRAS 18148[0440 in the L483 molecular cloud. The continuum emission is detected at the IRAS position at a level of 16 mJy, indicating a compact source with a mass of D0.13The delineates an envelope near the IRAS position, M _ . C 3 H 2 with a size of D 3000 AU ] 2000 AU in R.A. and decl. directions, respectively. A velocity gradient detected only along the axis of outÑow can be explained in terms of free-fall motion of the envelope. The HCO`line wing extends up to the velocity of^6 km s~1 relative to the systemic one, and the highvelocity material shows a symmetric bipolarity and extends over 2@ or 0.1 pc along the east-west direction. It is found that the outÑow material is clumpy and the opening angle is widest for the slowest moving component. The core component of the HCO`1È0 line exhibits an anti-infall asymmetry not only in interferometric but also in single dish observations. It is attributable to the slow isotropic outward motion of gas between the Ñattened envelope and the collimated outÑow.

LDCT-measured bone attenuation by volumetric methods showed good correlation with BMD measured by DXA and good diagnostic performance for identifying bone fragility.
