Nat Commun. 2017 Jun 01;8:15516. doi: 10.1038/ncomms15516.

Topological insulators are fascinating states of matter exhibiting protected edge states and robust quantized features in their bulk. Here we propose and validate experimentally a method to detect topological properties in the bulk of one-dimensional chiral systems. We first...

Ann Intensive Care. 2016 Dec;6(1):71. doi: 10.1186/s13613-016-0176-y. Epub 2016 Jul 22.

BACKGROUND: In acute kidney injury (AKI), useless continuation of renal replacement therapy (RRT) may delay renal recovery and impair patient's outcome. In this study, we aimed to identify predictive parameters that may help to a successful RRT weaning for...

Switching off the tackiness of a nanocomposite adhesive in 30 s via infrared sintering.

ACS applied materials & interfaces

Gurney RS, Dupin D, Nunes JS, Ouzineb K, Siband E, Asua JM, Armes SP, Keddie JL.

ACS Appl Mater Interfaces. 2012 Oct 24;4(10):5442-52. doi: 10.1021/am3013642. Epub 2012 Oct 03.

Soft adhesives require an optimum balance of viscous and elastic properties. Adhesion is poor when the material is either too solidlike or too liquidlike. The ability to switch tack adhesion off at a desired time has many applications, such...

Interaction of Derivatized Capped Iron(II) Porphyrin Complexes with CO and O(2).

Inorganic chemistry

Tang H, Dolphin D.
PMID: 11666802
Inorg Chem. 1996 Oct 23;35(22):6539-6545. doi: 10.1021/ic9600745.

A series of porphyrins strapped and capped by benzene and amidobenzene rings have been prepared. O(2) and CO bindings to their iron(II) complexes have been examined, and the role of hydrogen-bonding in stabilizing O(2) binding has been measured. Each...

The cation radicals of free base and zinc bacteriochlorin, bacteriochlorophyll, and bacteriopheophytin.

Proceedings of the National Academy of Sciences of the United States of America

Fajer J, Borg DC, Forman A, Felton RH, Dolphin D, Vegh L.
PMID: 16592150
Proc Natl Acad Sci U S A. 1974 Mar;71(3):994-8. doi: 10.1073/pnas.71.3.994.

One-electron oxidation of zinc tetraphenylbacteriochlorin and its metal-free base yielded stable cation radicals. Electron spin resonance hyperfine splittings were assigned by selective deuterations. These results indicate that the protons of the saturated rings of the bacteriochlorins carry large spin...

Swelling kinetics for a pH-induced latex-to-microgel transition.

Langmuir : the ACS journal of surfaces and colloids

Dupin D, Rosselgong J, Armes SP, Routh AF.
PMID: 17315901
Langmuir. 2007 Mar 27;23(7):4035-41. doi: 10.1021/la063278z. Epub 2007 Feb 22.

The kinetics of swelling of a series of six near-monodisperse, lightly cross-linked poly(2-vinylpyridine) latexes with mean diameters ranging from 380 to 1010 nm has been investigated by the pH jump method using a commercial stopped-flow instrument. These pH-responsive particles...

Production of S-Methylthioacetate by Brevibacterium linens.

Applied and environmental microbiology

Cuer A, Dauphin G, Kergomard A, Dumont JP, Adda J.
PMID: 16345424
Appl Environ Microbiol. 1979 Aug;38(2):332-4. doi: 10.1128/aem.38.2.332-334.1979.

Volatile sulfur compounds production by eight strains of Brevibacterium linens isolated from cheeses was demonstrated: methanethiol, dimethyldisulfide, and 2,3,4-trithiapentane. Four of these strains also produced S-methylthioacetate, an important aroma component of smear-coated cheeses. It is the first demonstrated microbiological...

Rheological behavior of acid-swellable cationic copolymer latexes.

Langmuir : the ACS journal of surfaces and colloids

PMID: 19831408
Langmuir. 2010 Feb 16;26(4):2736-44. doi: 10.1021/la9027699.

2-Vinylpyridine (2VP) was copolymerized with four different cross-linker densities ranging from 0.05 to 0.31 wt % divinylbenzene (DVB) via aqueous emulsion polymerization to produce a series of submicrometer-sized, lightly cross-linked P2VP latexes. Protonation of the 2VP residues leads to...

Synthesis of triple-stranded complexes using bis(dipyrromethene) ligands.

Inorganic chemistry

Inorg Chem. 2010 Dec 20;49(24):11550-5. doi: 10.1021/ic101694z. Epub 2010 Nov 11.

The reaction of an α-free, β,β'-linked bis(dipyrromethene) ligand with Fe(3+) or Co(3+) led to noninterconvertible triple-stranded helicates and mesocates. In the present context, a stable α-free ligand 2 has been developed and complexation of ligands 1 and 2 with...

Adv Pharmacol Sci. 2011;2011:153218. doi: 10.1155/2011/153218. Epub 2011 Oct 19.

Decrease of GABAergic transmission has been proposed to improve memory functions. Indeed, inverse agonists selective for α5 GABA-A-benzodiazepine receptors (α5IA) have promnesiant activity. Interestingly, we have recently shown that α5IA can rescue cognitive deficits in Ts65Dn mice, a Down...
