    Notes: Abstract  There have been conflicting reports about the occurrence and/or activity of atrial natriuretic peptide (ANP) sensitive guanylyl cyclase in the immune system. This study reports on ANP-sensitive guanylyl cyclase mRNA expression and guanylyl cyclase activity in human peripheral blood mononuclear cells (PBMC). Reverse transcription polymerase chain reaction (RT-PCR) shows that activated human PBMC of healthy blood donors express functional active ANP-sensitive guanylyl cyclase after vitro culture, whereas freshly isolated PBMC show neither specific mRNA for particulate guanylyl cyclase nor ANP-sensitive activity of this enzyme. To define the subpopulation of PBMC expressing this enzyme, cultivated PBMC were subfractioned and analyzed by RT-PCR and in situ PCR. Only CD3+ PBMC showed mRNA for ANP-sensitive guanylyl cyclase. Induction of the guanylyl cyclase required coincubation with other cells, indicating that a factor or factors secreted from cells other than CD3+ cells induces this expression. In summary, ANP-sensitive guanylyl cyclase is an inducible enzyme in human CD3+ PBMC in contrast to other cells where it is considered to be constitutive.

    IR absorption of highly vibrationally excited SF6 (1978)

    Notes: Abstract In a double-resonance experiment, the absorption of various CO2 laser lines by sulfur hexafluoride was measured, before and after the SF6 was pumped by a fixed frequency CO2 laser to a level of 5 quanta/molecule. The absorption is substantially shifted to longer wavelengths. But the short wavelength wing of the absorption band is not completely bleached. Instead a shoulder of several cm−1 width is left. This shoulder is probably important for the explanation of the infrared laser induced dissociation of SF6.
