Postoperativ persistierende Myokardischämie nach herzchirurgischen Eingriffen
Nach herzchirurgischen Eingriffen ist eine postoperativ persistierende Myokardischämie (ppMI) frühzeitig nur schwierig von der mit jeder Herzoperation einhergehenden Myokardschädigung zu unterscheiden. Die frü...

High Numerical-Aperture X-Ray Condensers for Transmission X-Ray Microscopes
In the near future transmission X-ray microscopes (TXM) will be installed at undulator X-ray sources, which generate highly collimated X-ray beams. To match a TXM to such a source X-ray condenser-monochromator...

Expansion of a B-lymphocyte clone producing IgM auto-antibodies encoded by a somatically mutated VHI gene in the spleen of an autoimmune patient
Seventy-six human B-cell hybridomas were obtained by fusing B lymphocytes from the spleen of a patient with chronic idiopathic thrombocytopenia (ITP). Two independent hybridoma clones producing IgM autoantibod...
