p-MPPF 4-(2’-methoxyphenyl)-1-[2’-[N-(2’’-pyridinyl)-p-fluorobenzamido] ethyl]piperazine is the para-fluorobenzoyl analog of the highly selective 5-HT1A antagonist WAY-100635. The one step procedure used ... [more ▼]

p-MPPF 4-(2’-methoxyphenyl)-1-[2’-[N-(2’’-pyridinyl)-p-fluorobenzamido] ethyl]piperazine is the para-fluorobenzoyl analog of the highly selective 5-HT1A antagonist WAY-100635. The one step procedure used to label p-MPPF with fluorine-18 (cyclotron produced positron emitter of 110 min half-life) leads to a radiopharmaceutical compound easily prepared on a large scale. The preliminary evaluations conducted in rats and cats are good reason to consider p-[18F]MPPF as an interesting reversible radioligand to study the 5-HT1A receptor family in humans with positron emission tomography (PET). In this paper we report a careful comparison between p-[18F]MPPF and [3H]8-OH-DPAT with autoradiography and quantitative densitometry in the same animal. All experiments were conducted in Sprague Dawley male rats. For p-[18F]MMPF, the results were obtained ex-vivo after an intravenous injection of high specific activity radioligand (0.8-1.5 Ci/µmol) in vigil (no anesthesia), free moving and unstressed animals. For the purpose, permanent cannulation of the posterior vena cava were realized at least four days in advance. The [3H]8-OH-DPAT results were obtained in vitro on adjacent coronal sections to the one used for the p-[18F]MPPF autoradiography. Quantitative densitometry was employed to compare the values obtained in relevant brain structures (frontal cortex, lateral septum, hippocampus, dorsal raphe, entorhinal cortex and cerebellum). The plot of the p-[18F]MPPF values obtained for each structure against the [3H]8-OH-DPAT results displayed a significant linear correlation. These results demonstrate that from a qualitative as well as quantitative point of view, the binding of p-[18F]MPPF is totally comparable to the one of [3H]8-OH-DPAT.

In the present study, sol-gel process is used to synthesize P-doped TiO2 xerogels by the cogelation method of a functionalized P alkoxide, (NH2-(CH2)2-NH-(CH2)2-P(O)-(OC2H5)2) with Ti(OC3H7)4 in either 2 ... [more ▼]

In the present study, sol-gel process is used to synthesize P-doped TiO2 xerogels by the cogelation method of a functionalized P alkoxide, (NH2-(CH2)2-NH-(CH2)2-P(O)-(OC2H5)2) with Ti(OC3H7)4 in either 2-methoxyethanol or isopropanol. The phosphorus-doping improved the thermal stability of titania and decreased the phase transformation of anatase into rutile. This modification by phosphorus shifted the absorption edge of titania to the visible region as proved by Diffuse reflectance measurements, and thus offers the possibility to produce visible light effective TiO2 photocatalyst. The excellent photocatalytic activity of P-doped TiO2 xerogels compared to pure TiO2 could be explained by its high surface area and small TiO2-anatase crystallite size. From these results, it was proved by using three different models that phosphorus intrinsically influences the photocatalytic activity. [less ▲]

Models of alpha Cen A & B have been computed using the masses determined by Pourbaix et al. (2002) and the data derived from the spectroscopic analysis of Neuforge and Magain (1997). The seismological data obtained by Bouchy and Carrier (2001, 2002) do help improve our knowledge of the evolutionary status of the system. All the constraints are satisfied with a model which gives an age of about 6 Gyr for the binary. [less ▲]

Traduction française du célèbre chapitre de Peter Carruthers, "HOP over FOR, HOT Theory". L'auteur y soutient que les théories représentationnelles de premier ordre (Dretske, Tye, et alii) et les théories actualistes de la pensée d'ordre supérieur (e.g., Rosenthal) se heurtent à deux sérieuses difficultés: l'incapacité à rendre compte des concepts d'expérience recognitionnels et l'incapacité à expliquer pourquoi certains états sont phénoménalement conscients et d'autres non. P. Carruthers introduit et défend une théorie alternative, d'après laquelle un état mental est phénoménalement conscient si et seulement s'il est mis à la disposition d'une pensée d'ordre supérieur possible. Cette théorie est baptisée théorie dispositionnelle de la pensée d'ordre supérieur ou "théorie du double contenu". [less ▲]

Le texte qui suit est la traduction française d’une conférence prononcée à Berlin le 8 décembre 1913 par Paul Natorp, l’un des principaux représentants – avec Hermann Cohen et Ernst Cassirer – de l’école néokantienne de Marbourg. Natorp y expose à nouveaux frais l’interprétation de l’idéalisme platonicien qu’il avait défendue en 1903, à partir d’une analyse systématique et minutieuse des dialogues de Platon, dans sa Platos Ideenlehre et, de façon condensée, dans son article de 1911 sur « La logique de Platon »1. Comme le montre la conférence, cette interprétation consiste à combattre la séparation aristotélicienne entre logique et métaphysique – ou encore entre pensée et être, Denken et Sein – pour voir dans la théorie platonicienne de Idées une théorie de l’« être-pensé » qui formerait la matrice d’un idéalisme critique ou transcendantal.
