The subunit a of the guinea pig fertilin (previously known as PH-30, an integral membrane protein involved in sperm-egg binding and fusion) is predicted to be a potential fusion protein.The structure of this putative fusion protein was analysed by molecular modeling and we have found a peptidic sequence of 17 residues (D83-P99) organized in helix that inserts obliquely in lipid phases. The effect of ths synthesized peptide was studied on a model membrane by 3lP NMR and light scattering. It appears to increase the size of lipid vesicles and induces structural odifications. We interpret these observations as a destabilization of the lipid organization by this peptide because of its tilted insertion in phospholipid layers. This destabilization could favor membrane fusion. [less ▲]

Stratospheric ozone is an important constituent of the Earth's atmosphere since it protects the biosphere from the most harmful ultraviolet radiations emitted by the sun. Some human activiites such as the use of man-mande chlorofluorocarbons have resulted in major destruction of ozone, in particular in the polar regions of the stratosphere. The Montreal Protocol has been successful in limiting the emissions of ozone depleting substances such as the complete ozone recovery is expected to take place in 2050 over northern mid-latitudes.

L’ozone (O3) est présent dans l’atmosphère terrestre en quantité limitée, avec un maximum de concentration entre 15 et 50 km d’altitude. Cette molécule y joue un rôle essentiel en filtrant les rayons solaires ultraviolets dont les effets sur les êtres vivants peuvent être nocifs. L’influence des activités humaines sur la couche d’ozone stratosphérique s’est manifestée dès le début des années 1980, principalement au dessus de l’Antarctique, où une baisse significative de la quantité totale d’ozone a été observée chaque printemps (ce que l’on nomme communément le «trou dans la couche d’ozone»). Depuis la mise en oeuvre du Protocole de Montréal en 1987, les émissions mondiales de substances halogénées à l’origine de cette destruction ont fortement diminué, laissant présager, sous nos latitudes, un retour à la normale de l’épaisseur de la couche d’ozone vers 2050.

Fatty acid spin labels have been included into liposomes and micelles, in order to study the photochemical behavior of merocyanine 540 toward nitroxyl radicals situated at various depths in the bilayer or the surfactant layer. Visible illumination of the dye, either free in ethanol or bound to liposomes or micelles, leads to the reduction of the electron spin resonance signal of the label. The efficiency of the interaction between merocyanine 540 and spin labels depends on the depth at which the nitroxyl moiety is localized in the micelle or vesicle. Fluorescence measurements indicate that the first excited singlet state of merocyanine 540 is not directly implicated in the reaction mechanism. Flash photolysis experiments conducted in aqueous solutions of hexadecyltrimethylammonium bromide micelles show that the presence of nitroxyl radical decreases the rate constant of triplet decay in a concentration-dependent fashion. The corresponding quenching rate constant (kq) is determined for the different spin labels. The kq values and the reduction rates of ESR signal show the same dependence on the localization of the nitroxyl moiety in the micelles. [less ▲]

We studied the contribution of the main olfactory system to mate recognition and sexual behavior in female mice. Female mice received an intranasal irrigation of either a zinc sulfate (ZnSO4) solution to destroy the main olfactory epithelium (MOE) or saline (SAL) to serve as control. ZnSO4-treated female mice were no longer able to reliably distinguish between volatile as well as nonvolatile odors from an intact versus a castrated male. Furthermore, sexual behavior in mating tests with a sexually experienced male was significantly reduced in ZnSO4-treated female mice. Vomeronasal function did not seem to be affected by ZnSO4 treatment: nasal application of male urine induced similar levels of Fos protein in the mitral and granule cells of the accessory olfactory bulb (AOB) of ZnSO4 as well as SAL-treated female mice. Likewise, soybean agglutinin staining, which stains the axons of vomeronasal neurons projecting to the glomerular layer of the AOB was similar in ZnSO4-treated female mice compared to SAL-treated female mice. By contrast, a significant reduction of Fos in the main olfactory bulb was observed in ZnSO4-treated females in comparison to SAL-treated animals, confirming a substantial destruction of the MOE. These results show that the MOE is primarily involved in the detection and processing of odors that are used to localize and identify the sex and endocrine status of conspecifics. By contrast, both the main and accessory olfactory systems contribute to female sexual receptivity in female mice. [less ▲]
