Norwegian airline passengers are not more afraid of flying after the terror act of September 11. The flight anxiety, however, is significantly attributed to acts of terrorism.

The aim of this paper is to study: (1) the prevalence of flight anxiety among Norwegian airline passengers; (2) situations that may be of concern during flights and situations not related to flying; (3) whether passengers feel more afraid after the terror act of September 11, 2001; and (4) whether passengers were more afraid in 2002 than in 1986.A questionnaire was distributed during domestic flights in Norway in 1986 and 2002. To asses flight anxiety, a six point scale was used, from 0 = not afraid at all, to 5 = always very afraid, and sometimes avoid flying because of that.

Cellular location and age-dependent changes of the regulatory subunits of cAMP-dependent protein kinase in rat testis.

This study was undertaken to examine the expression and cellular location of the various cAMP-dependent protein kinase (PKA) subunits in different testicular cell types, using cDNA probes, isoenzyme-specific antibodies and activity measurements. Amounts of mRNA and protein were examined in cultured Sertoli cells, cultured peritubular cells, germ cells (pachytene spermatocytes, round spermatids), Leydig cell tumours as well as whole testes from rats of various ages. In Sertoli cells, there was a good correlation between the amount of mRNA and the respective immunoreactive proteins.

Exogenous substrate stimulates autodephosphorylation of cyclic-AMP-dependent protein kinase II.

The autophosphorylated regulatory subunit (32P-RII) of cyclic-AMP-dependent protein kinase II was efficiently dephosphorylated by its C subunit in the absence of added ADP, provided that Mg/ATP and a standard protein kinase peptide substrate were present. This raises the possibility that autodephosphorylation could be significant in the intact cell. Only the cyclic-AMP-complexed free form of 32P-RII was efficiently dephosphorylated, indicating that the autodephosphorylation was intermolecular.

Identification, characterization, and hormonal regulation of 3', 5'-cyclic adenosine monophosphate-dependent protein kinases in rat Sertoli cells.

Recent studies have disclosed multiple isoforms of regulatory (R) and catalytic (C) subunits of cAMP-dependent protein kinase (PKA) at the protein and messenger RNA (mRNA) levels. The purpose of the present study was to identify, characterize, and quantify individual R subunits in rat Sertoli cells both at the mRNA and protein levels. Unstimulated Sertoli cells contain high levels of R (approximately 9.
