The neural mechanisms underlying hypnosis and especially the modulation of pain perception by hypnosis remain obscure. Using PET we first described the distribution of regional cerebral blood flow during the hypnotic state. Hypnosis relied on revivification of pleasant autobiographical memories and was compared to imaging autobiographical material in "normal alertness". The hypnotic state was related to the activation of a widespread set of cortical areas involving occipital, parietal, precentral, premotor, and ventrolateral prefrontal and anterior cingulate cortices. This pattern of activation shares some similarities with mental imagery, from which it mainly differs by the relative deactivation of precuneus. Second, we looked at the anti-nociceptive effects of hypnosis. Compared to the resting state, hypnosis reduced pain perception by approximately 50%. The hypnosis-induced reduction of affective and sensory responses to noxious thermal stimulation were modulated by the activity in the midcingulate cortex (area 24a'). Finally, we assessed changes in cerebral functional connectivity related to hypnosis. Compared to normal alertness (i.e., rest and mental imagery), the hypnotic state, significantly enhanced the functional modulation between midcingulate cortex and a large neural network involved in sensory, affective, cognitive and behavioral aspects of nociception. These findings show that not only pharmacological but also psychological strategies for pain control can modulate the cerebral network involved in noxious perception. [less ▲]

Les marges sud et nord du Sahara sont soumises à des processus de dégradation anciens attestés par de nombreux travaux de terrain. Ils coïncident avec l'occurrence d'une sécheresse sévère sur les 3 sites d'étude, débutée dans les années 1970 en Algérie (piémont sud de l'Atlas Saharien), au Maroc (bassin de l'oued Dadès) et en Mauritanie (lac d'Aleg, Brakna). Les suivis diachroniques par télédétection satellitaire (Landsat et SPOT) et aérienne (1954 à 2002) et des observations récentes, montrent la pérennité voire l'extension de certaines zones de dégradation localisées à proximité des agglomérations et points d'eau, malgré le retour des précipitations. Le rythme et les modalités de développement des dynamiques en œuvre, qui prennent la forme d'une dégradation qualitative et quantitative des couverts végétaux steppiques et de savane ainsi qu'une revivification des dunes d'Aleg, attestent du rôle prépondérant de certains activités humaines dans les processus de dégradation de ces milieux, en corrélation avec la crise climatique dont on peut se demander si elle n'est pas devenue un facteur secondaire. Sans ignorer les enjeux socio-économiques de développement, notre démarche vise à comprendre les logiques d'action des dynamiques complexes parfois abusivement désignées sous le terme simplificateur de «désertification».

In this note, we give an alternative proof of the following result. Let p,q>=2 be two multiplicatively independent integers. If an infinite set of integers is both p- and q-recognizable, then it is syndetic. Notice that this result is needed in the classical proof of the celebrated Cobham’s theorem. Therefore the aim of this paper is to complete [13] and [1] to obtain an accessible proof of Cobham’s theorem. [less ▲]

The Chameleon peptide (Cham) is a peptide designed from two regions of the GB1 protein, one folded as an alpha-helix and the other as a beta structure. Depending on the environment, the Cham peptide adopts an alpha or a beta conformation when inserted in different locations of GB1. This environment dependence is also observed for tilted peptides. These short protein fragments, able to destabilise organised system, are mainly folded in beta structure in water and in alpha helix in a hydrophobic environment, like the lipid bilayer. In this paper, we tested whether the Cham peptide can be qualified as a tilted peptide. For this, we have compared the properties of Cham peptide (hydrophobicity, destabilising properties, conformation) to those of tilted peptides. The results suggest that Cham is a tilted peptide. Our study, together the presence of tilted fragments in transconformational proteins, suggests a relationship between tilted peptides and structural lability. [less ▲]

Mossbauer-effect and microwave absorption experimental evidence unambiguously demonstrates the presence of slow, similar to 450 MHz, tunneling of magnetic europium between four equivalent sites in Eu8Ga16Ge30, a stoichiometric clathrate. Remarkably, six of the eight europium atoms, or 11% of the constituents in this solid, tunnel between these four sites separated by 0.55 angstrom. The off centering of the atoms or ions in crystalline clathrates appears to be a promising route for producing Rabi oscillators in solid-state materials. [less ▲]

The estrogen deficit occurring at menopause manifests itself under various modalities in the diverse organs and their functions. Skin does not escape this global involutive process. In addition to the effects of chronological ageing, sunlight exposure and other environmental and endogenous stimuli, the climacteric appears to exert some dramatic consequences on skin biology and aspect. The epidermis, its adnexae and the dermis are altered by this process. The epidermis may become xerotic and exhibits altered functions. The dermis thins out and its elasticity decreases in concert with the decline in bone mass. The skin microcirculation is impaired. These aspects are some of the better-worked out skin climacteric changes of which in turn seem to be stabilized or in part reversible with hormone replacement therapy (HRT). [less ▲]
