PMID: 23243439
Evid Based Complement Alternat Med. 2012;2012:371273. doi: 10.1155/2012/371273. Epub 2012 Nov 11.

Aims of the present study were to investigate effects of Balanophora spicata (BS) on antinociception and anti-inflammation both in vivo and in vitro. Crude extract of BS inhibited vascular permeability induced by histamine, serotonin, bradykinin, and PGE(2), but not...

Synthesis, structure, and theoretical study of trifluoromethyl derivatives of C84(22) fullerene.

Chemistry (Weinheim an der Bergstrasse, Germany)

Chang K, Fritz MA, Tamm NB, Goryunkov AA, Sidorov LN, Chen C, Yang S, Kemnitz E, Troyanov SI.
PMID: 23180725
Chemistry. 2013 Jan 07;19(2):578-87. doi: 10.1002/chem.201202568. Epub 2012 Nov 23.

Trifluoromethylation of higher fullerene mixtures with CF(3)I was performed in ampoules at 400 to 420 and 550 to 560 °C. HPLC separation followed by crystal growth and X-ray diffraction studies allowed the structure elucidation of nine CF(3) derivatives of...

Zhang YL, Wang RC, Cheng K, Ring BZ, Su L.
PMID: 28443208
Cancer Biol Med. 2017 Feb;14(1):90-99. doi: 10.20892/j.issn.2095-3941.2016.0086.

Ras-associated protein-1 (Rap1), a small GTPase in the Ras-related protein family, is an important regulator of basic cellular functions (e.g., formation and control of cell adhesions and junctions), cellular migration, and polarization. Through its interaction with other proteins, Rap1...

Tuning Edge States in Strained-Layer InAs/GaInSb Quantum Spin Hall Insulators.

Physical review letters

Du L, Li T, Lou W, Wu X, Liu X, Han Z, Zhang C, Sullivan G, Ikhlassi A, Chang K, Du RR.
PMID: 28949710
Phys Rev Lett. 2017 Aug 04;119(5):056803. doi: 10.1103/PhysRevLett.119.056803. Epub 2017 Aug 03.

We report on a class of quantum spin Hall insulators (QSHIs) in strained-layer InAs/GaInSb quantum wells, in which the bulk gaps are enhanced up to fivefold as compared to the binary InAs/GaSb QSHI. Remarkably, with consequently increasing edge velocity,...

SU-E-T-161: SOBP Beam Analysis Using Light Output of Scintillation Plate Acquired by CCD Camera.

Medical physics
