Skin disorders in Parkinson's disease: potential biomarkers and risk factors.

Clinical, cosmetic and investigational dermatology

Ravn AH, Thyssen JP, Egeberg A.
PMID: 28331352
Clin Cosmet Investig Dermatol. 2017 Mar 09;10:87-92. doi: 10.2147/CCID.S130319. eCollection 2017.

Parkinson's disease (PD) is one of the most common neurodegenerative disorders, characterized by a symptom triad comprising resting tremor, rigidity, and akinesia. In addition, non-motor symptoms of PD are well recognized and often precede the overt motor manifestations. Cutaneous...

Tailoring Building Blocks and Their Boundary Interaction for the Creation of New, Potentially Superhard, Carbon Materials.

Advanced materials (Deerfield Beach, Fla.)

Yao M, Cui W, Du M, Xiao J, Yang X, Liu S, Liu R, Wang F, Cui T, Sundqvist B, Liu B.
PMID: 26037719
Adv Mater. 2015 Jul 08;27(26):3962-8. doi: 10.1002/adma.201500188. Epub 2015 Jun 02.

A strategy for preparing hybrid carbon structures with amorphous carbon clusters as hard building blocks by compressing a series of predesigned two-component fullerides is presented. In such constructed structures the building blocks and their boundaries can be tuned by...

Photocatalysis. A multi-faceted concept for green chemistry.

Chemical Society reviews

Ravelli D, Dondi D, Fagnoni M, Albini A.
PMID: 19551179
Chem Soc Rev. 2009 Jul;38(7):1999-2011. doi: 10.1039/b714786b. Epub 2009 Apr 21.

Photocatalysis (by semiconductors, molecules and ions) is used in such diverse applications as water hydrolysis for producing hydrogen as fuel, organic synthesis and the recovery of polluted effluents. This tutorial review discusses the common principles of such applications and...

Synthesis, characterization and electrochemical properties of stable osmabenzenes containing PPh3 substituents.

Chemistry (Weinheim an der Bergstrasse, Germany)

Zhang H, Wu L, Lin R, Zhao Q, He G, Yang F, Wen TB, Xia H.
PMID: 19219873
Chemistry. 2009;15(14):3546-59. doi: 10.1002/chem.200801774.

Treatment of [OsCl(2)(PPh(3))(3)] with HC[triple bond]CCH(OH)C[triple bond]CH/PPh(3) produces the osmabenzene [Os{CHC(PPh(3))CHC(PPh(3))CH}Cl(2)(PPh(3))(2)][OH] (2), which is air stable in both solution and solid state. The key intermediate of the one-pot reaction, [OsCl(2){CH=C(PPh(3))CH(OH)C[triple bond]CH}(PPh(3))(2)] (3), and the related complex [Os(NCS)(2){CHC(PPh(3))CH(OH)C[triple bond]CH}(PPh(3))(2)] (7)...

Calculation of higher-order wave-mixing spectra.

Optics letters

Trebino R, Rahn LA.
PMID: 19767941
Opt Lett. 1990 Apr 01;15(7):354-6. doi: 10.1364/ol.15.000354.

Using diagrammatic perturbation theory, we calculate the higher-order susceptibility for the n-wave process, omega(0) = (n/2 - 1)(omega(1) - omega(2)) + omega(1), in a phase-matched n-wave-mixing geometry. We include the 16 Zeeman and hyperfine levels of the sodium ground...

Spatially resolved infrared absorption measurements: application of an optical Stark effect.

Optics letters

Farrow RL, Rahn LA.
PMID: 19701343
Opt Lett. 1981 Mar 01;6(3):108-10. doi: 10.1364/ol.6.000108.

A new technique for obtaining point measurements in gases by infrared absorption is described. The method is based on a recently discovered quadratic Stark effect on vibrational and rotational molecular transitions that is induced by high-intensity optical fields. Detectivity...

Carrier transport and luminescence properties of nanocomposites of poly[2-methoxy-5-(2-ethyl hexyloxy)-p-phenylene vinylene] and dehydrated nanotubes titanic acid.

Journal of nanoscience and nanotechnology

Zhang T, Xu Z, Liu R, Teng F, Wang Y, Xu X.
PMID: 18283809
J Nanosci Nanotechnol. 2007 Dec;7(12):4318-21. doi: 10.1166/jnn.2007.894.

The carrier transport capability and luminescence efficiency of poly(2-methoxy-5-(2-ethyl hexyloxy)-p-phenylene vinylene) (MEH-PPV) films are enhanced by doping with dehydrated nanotubed titanic acid (DNTA). MEH-PPV molecules, either wrapped on the outer surface of or encapsulated into DNTA pores, have a...

Regio- and stereoselectivity in the decatungstate photocatalyzed alkylation of alkenes by alkylcyclohexanes.

Chemistry (Weinheim an der Bergstrasse, Germany)

Dondi D, Ravelli D, Fagnoni M, Mella M, Molinari A, Maldotti A, Albini A.
PMID: 19609992
Chemistry. 2009 Aug 10;15(32):7949-57. doi: 10.1002/chem.200900810.

Tetrabutylammonium decatungstate (WO) photocatalyzes radical alkylation reactions starting directly from alkanes. When using tert-butylcyclohexane and methylcyclohexane as the radical precursors, the addition to electrophilic alkenes (beta,beta-dialkylmethylenemalononitriles, acrylonitrile, methyl acrylate, methyl vinyl ketone) is regioselective and exclusively gives 3- and...
