The neuropeptide substance P, the venom peptide mastoparan and the synthetic polyamine compound 48/80 activate rat peritoneal mast cells, leading to rapid histamine release by exocytosis. Although these effects are inhibited by pertussis toxin and involve a transient increase in IP3, no selective membrane receptors have been identified. However, it has recently been shown that these compounds activate G proteins in vitro. Here Yves Landry and colleagues discuss the proposal that direct activation of G protein is the physiological mechanism of action of substance P on rat peritoneal mast cells, this mechanism being mimicked by mastoparan and 48/80, and possibly by other cationic amphiphilic peptides such as kinins. These compounds might be of help in defining the interaction between membrane receptors and G proteins. [less ▲]

The molecular mechanism of action of several non-immunological histamine releasers has been investigated using pertussis toxin which interfers, via ADP-ribosylation, with some G-proteins. Pertussis toxin (100 ng/ml) inhibited histamine release induced by compound 48/80, substance P, mastoparan, peptide 401, bradykinin and spermine showing that a G-protein sensitive to pertussis toxin was involved in the non-immunological histamine release. All these compounds directly activate purified G-proteins. The sensitivity to pertussis toxin of this direct stimulatory effect was demonstrated for compound 48/80, mastoparan and substance P. Altogether these results suggest that a direct activation of G-protein might be the molecular mechanism of action of histamine secretagogues acting through a pertussis toxin sensitive G-protein and in this way mimic agonist-ligand receptor interaction.

The authors report on the fabrication and characterization of photodetectors based on nitrogen-ion-implanted GaAs and the annealing dynamics in these devices. An energy of 400 keV was used to implant N ions in a GaAs substrate at an ion concentration of 1 1016 cm−2. Dark current measurements as well as measurements under illumination show that the material properties rapidly change during the annealing process. Photodetectors based on nitrogen-implanted GaAs materials with annealing temperatures up to 400 °C exhibit a subpicosecond carrier lifetime up to 0.6 ps. These properties make nitrogen-ion-implanted GaAs an ideal material for ultrafast photodetectors, as alternative to low-temperature-grown GaAs. [less ▲]

In this paper we generalize results of P. Le Duff to genus n hyperelliptic curves. More precisely, let C/Q be a hyperelliptic genus n curve and let J(C) be the associated Jacobian variety. Assume that there exists a prime p such that J(C) has semistable reduction with toric dimension 1 at p. We provide an algorithm to compute a list of primes l (if they exist) such that the Galois representation attached to the l-torsion of J(C) is surjective onto the group GSp(2n, l). In particular we realize GSp(6, l) as a Galois group over Q for all primes l in [11, 500000]. [less ▲]
