Labdane dimers from Xylopia aromatica
(Elsevier B.V., 1999-07-01)
From the stem bark of Xylopia aromatica (Annonaceae), have been isolated two new labdane dimers as their methyl esters, together with the known compounds ent-labda-8(17),13(16),14-trien-18-oic acid, sitosterol and stigmasterol. ...

Interaction between the antimicrobial peptide Aurein 1.2 dimer and mannans
(Springer, 2014-11-01)
We have previously described the structure and the ability of a dimeric analog of the antimicrobial peptide Aurein 1.2 to aggregate Candida albicans. In this study, circular dichroism and fluorescence spectroscopy data ...
EIF5A dimerizes not only in vitro but also in vivo and its molecular envelope is similar to the EF-P monomer
(2013-02-01)
The protein eukaryotic initiation factor 5A (eIF5A) is highly conserved among archaea and eukaryotes, but not in bacteria. Bacteria have the elongation factor P (EF-P), which is structurally and functionally related to ...

Immunosensors made with layer-by-layer films on chitosan/gold nanoparticle matrices to detect d-dimer as biomarker for venous thromboembolism
(2018-01-01)
We report on immunosensors to detect D-dimer, a biomarker of venous thromboembolism, which are made with layer-bylayer (LbL) films containing immobilized anti-D-dimer monoclonal antibody alternated with a layer of chitosan/gold ...
Dimerization of α-pinene, using Phosphotungstic acid supported on SiO2 as catalyst
(Bentham Science Publishers, 2014-01)
The α-pinene dimerization in liquid phase was studied by using phosphotungstic acid catalysts H3PW12O40, (HPW) supported on commercial silica. These catalysts were characterized by XRD, FT-IR and FT-IR of pyridine adsorbed. ...
Site-bond percolation of heteronuclear dimers irreversibly deposited on square lattices
(American Physical Society, 2017-12)
A generalization of the site-bond percolation problem was studied, in which pairs of neighboring sites (site dimers) and bonds are occupied irreversibly, randomly, and independently on homogeneous square surfaces. A dimer ...
