X-ray Spectroscopy of Bal and Mini-bal Qsos

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...

Therapeutic applications of BAL.

Although BAL had been used for therapeutic purposes prior to its use as a diagnostic procedure and the value of BAL in the exploration and management of some interstitial lung diseases is now well established, its place in therapy is controversially reported. As early as 1963, RAMIREz et al. [280] were the frrst to perform a whole lung lavage (WLL) using a large volume of fluid in patients with...

Biphenotypic Acute Leukaemia (BAL)

Biphenotypic acute leukaemia (BAL) is an uncommon disease. As strict diagnostic criteria have only recently been established, the precise incidence among acute leukaemias is uncertain, although it is likely to account for approximately 5% of all acute leukaemias. BAL can be de novo or secondary to previous cytotoxic therapy. It has been included in the WHO classification of haemopoietic maligna...

MALT1 Rearrangements in BAL Fluid.

We read with great interest the article by Kido et al 1 in an issue of CHEST (January 2012) demonstrating mucosa-associated lymphoid tissue (MALT) lymphoma translocation gene 1 rearrangements in BAL fl uid (BALF) in four of fi ve cases of pulmonary MALT lymphoma. The use of BALF is debated, but the authors elegantly demonstrate that BALF may be useful for the diagnosis of pulmonary disease, par...
