    Notes: The homologous nature and morphological similarities between cutaneous and salivary gland tumors have been well documented. This is especially true of the monomorphic adenoma, eccrine spiradenoma and cylindroma. Prior to the first full clinical and pathological description, about twenty-five years ago, the lesion of eccrine spiradenoma had been given multiple synonyms.This report is of a patient with an eccrine spiradenoma in the buttock and dermal-type cylindroma of the parotid gland. This may represent the transformation of pleuripotential basal cells originating in the parotid and eccrine sweat gland.

    Notes: Abstract The transient field technique has been used to determine theg-factor of the 4 2 + state at 6.010MeV excitation in24Mg. The deduced value ofg=+0.5(4) is consistent with collective model expectations. Further, the equality within experimental accuracies, of the g-factors of the 2 1 + , 2 2 + , 4 1 + and 4 2 + states agrees with theoretical predictions for thisT=0 self-conjugate nucleus, in contrast to the results for20Ne.

    Notes: Abstract Employing the time-integral PAC technique with an external magnetic field, the g-factor of the 19/2+ state at 2,125.6 keV in135Ce was determined to be g=−0.07(1). This value favours a predominant (h 11 2/−2 s 1 2/−1 ) neutron configuration for this level. Its meanlife has been redetermined with improved precision to be τ=11.8(5) ns.

    Notes: Abstract In the hydrogen bubble chamber study of the4Hep→dppn reaction at incident alpha 8.6 GeV/c momentum the structures in the two-proton effective mass distribution are observed at 2,035±15 MeV and 2,137±15 MeV. Possible nature of the effect is discussed.

    Notes: Abstract The role of histamine-1 receptors in modulating gastric acid secretion was evaluated in anesthetized dogs with gastric fistulas. Histamine receptor agonists were infused directly into the gastric artery supplying the fundus to avoid any systemic hemodynamic effects. Two experimental approaches were taken to try to determine whether histamine-1 receptors participate in the control of acid secretion. Firstly, we measured the effect of H1-receptor antagonist, hydroxyzine dihydrochloride, on histamine and dimaprit stimulated acid secretion. Secondly, we measured the effect of H1-receptor agonist on dimaprit stimulated gastric secretion. Although H1-receptor antagonist enhanced stimulated gastric acid secretion to histamine, the antagonist also enhanced stimulated gastric acid secretion to dimaprit (H2-agonist), suggesting that the enhanced gastric acid secretion after administration of H1-receptor antagonist is not becacuse of the inhibition of histamine receptor at the gastric fundus. In addition, two doses of H1-receptor agonist infused into the gastric fundus had no effect on dimaprit stimulated gastric acid secretion. These data suggest that H1-receptors do not modulate gastric acid secretion at the level of the gastric fundus in the dog.

    Notes: Abstract  Pax proteins play a diverse role in early animal development and contain the characteristic paired domain, consisting of two conserved helix-turn-helix motifs. In many Pax proteins the paired domain is fused to a second DNA binding domain of the paired-like homeobox family. By amino acid sequence alignments, secondary structure prediction, 3D-structure comparison, and phylogenetic reconstruction, we analyzed the relationship between Pax proteins and members of the Tc1 family of transposases, which possibly share a common ancestor with Pax proteins. We suggest that the DNA binding domain of an ancestral transposase (proto-Pax transposase) was fused to a homeodomain shortly after the emergence of metazoans about one billion years ago. Using the transposase sequences as an outgroup we reexamined the early evolution of the Pax proteins. Our novel evolutionary scenario features a single homeobox capturing event and an early duplication of Pax genes before the divergence of porifera, indicating a more diverse role of Pax proteins in primitive animals than previously expected.

    Notes: Abstract Somatostatin, secretin, and glucagon have been shown to inhibit gastric acid secretionin vivo and thus have been postulated to act directly on the parietal cell. To test the hypothesis that these peptides directly influence the acid secretory cells, we studied the effect of the three gastrointestinal hormones using aminopyrine uptake as an index of acid production. The parietal cells were stimulated to increase aminopyrine uptake by submaximal concentrations of histamine (10−6 mol/l), methacholine (10−6 mol/l), and pentagastrin (10−6 mol/l), but in no concentrations did these gastrointestinal hormones affect any of the secretagogues' response. Our data suggest that gastrointestinal peptides do not modulate acid secretion at the parietal cell level.
