Organic Geochemistry [Biogéochimie moléculaire]

Abstract: The widely distributed aromatic di- and triterpenoids from higher plants occurring in sediments are formed by diagenetic microbial processes affecting their precursor plant lipids. These compounds and their stable isotopic composition (δ13C and δ2H) have the potential to be used for palaeoenvironmental and palaeoclimatic studies. In the present study, the isotopic composition of di-...[En savoir plus]

Organic Geochemistry [Biogéochimie moléculaire]

Abstract: Birch bark tar, an organic material frequently encountered during archaeological excavations, has been identified from its lipid composition on the cracks of a ceramic dated to the late Neolithic. Lipids of this black substance were dominated by a characteristic triterpenoid assemblage of lupane-related triterpenoids from birch bark, together with their thermal degradation products...[En savoir plus]

Inorganica Chimica Acta [POMAM]

Abstract : Mononuclear chromium(III) complexes of formula mer-[CrIIICl3(pz*H)3] (pz*H = pyrazole (pzH), and substituted pyrazoles: 3-Me-pzH, 4-Me-pzH, 4-Cl-pzH, 4-Br-pzH, 4-I-pzH) and trans-[CrIIICl2(pzH)4]Cl were synthesized from reactions of CrCl3 hydrate and pyrazole ligands and crystallographically characterized. The fluxional behavior of the complexes, attributed to pyrazole...[En savoir plus]

Front. Mol. Biosci. [Biophysique des membranes et RMN]

Abstract : MHC class II receptors carry important function in adaptive immunity and their malfunctioning is associated with diabetes type I, chronic inflammatory diseases and other autoimmune diseases. The protein assembles from the DQ alpha-1 and DQ beta-1 subunits where the transmembrane domains of these type I membrane proteins have been shown to be involved in homo- and heterodimer...[En savoir plus]

J Membrane Biol [Biophysique des membranes et RMN]

Abstract : The major histocompatibility complex class II (MHC II) membrane proteins are key players in the adaptive immune response. An aberrant function of these molecules is associated with a large number of autoimmune diseases such as diabetes type I and chronic inflammatory diseases. The MHC class II is assembled from DQ alpha 1 and DQ beta 1 which come together as a heterodimer through...[En savoir plus]

JACS [POMAM]

Abstract : Two molecular spin triangles are studied with pulsed Electron Paramagnetic Resonance (EPR) spectroscopy to assess their magnetoelectric (ME) couplings. [Fe3O(PhCOO)6(py)3]ClO4·py (Fe3) is characterized by strong Dzyaloshinskii-Moriya interactions (DMI) which induce important magnetoanisotropy, whereas the DMI in [Cr3O(PhCOO)6(py)3]ClO4·0.5py (Cr3) is 1-2 orders of magnitude weaker. By...[En savoir plus]
