Parecoxib Provides Analgesic and Opioid-Sparing Effects Following Major Orthopedic Surgery: A Subset Analysis of a Randomized, Placebo-Controlled Clinical Trial.

Pain and therapy

Diaz-Borjon E, Torres-Gomez A, Essex MN, Salomon P, Li C, Cheung R, Parsons B.
PMID: 28255955
Pain Ther. 2017 Jun;6(1):61-72. doi: 10.1007/s40122-017-0066-5. Epub 2017 Mar 02.

INTRODUCTION: Orthopedic surgeries are among the most common and most painful surgeries performed. A multimodal analgesic approach is recommended to reduce opioid consumption, provide effective pain relief, and improve outcomes following surgery. This study examined the efficacy and opioid-sparing...

Synthesis of Benzodihydrofurans by Asymmetric C-H Insertion Reactions of Donor/Donor Rhodium Carbenes.

Chemistry (Weinheim an der Bergstrasse, Germany)

Lamb KN, Squitieri RA, Chintala SR, Kwong AJ, Balmond EI, Soldi C, Dmitrenko O, Castiñeira Reis M, Chung R, Addison JB, Fettinger JC, Hein JE, Tantillo DJ, Fox JM, Shaw JT.
PMID: 28544228
Chemistry. 2017 Sep 04;23(49):11843-11855. doi: 10.1002/chem.201701630. Epub 2017 Aug 10.

Metal carbenes appended with two electron-donating groups, known as "donor/donor" carbenes, undergo diastereo- and enantioselective rhodium-catalyzed C-H insertion reactions with ether substrates to form benzodihydrofurans. Unlike the reactions of metal carbenes with electron-withdrawing groups attached, the attenuated electrophilicity enables...

Fast image restoration for spatially varying defocus blur of imaging sensor.

Sensors (Basel, Switzerland)

Cheong H, Chae E, Lee E, Jo G, Paik J.
PMID: 25569760
Sensors (Basel). 2015 Jan 06;15(1):880-98. doi: 10.3390/s150100880.

This paper presents a fast adaptive image restoration method for removing spatially varying out-of-focus blur of a general imaging sensor. After estimating the parameters of space-variant point-spread-function (PSF) using the derivative in each uniformly blurred region, the proposed method...

Polarization-independent light emission enhancement of ZnO/Ag nanograting via surface plasmon polariton excitation and cavity resonance.

ACS applied materials & interfaces

Gwon M, Lee YU, Wu JW, Nam D, Cheong H, Kim DW.
PMID: 24850379
ACS Appl Mater Interfaces. 2014 Jun 11;6(11):8602-5. doi: 10.1021/am5014024. Epub 2014 May 29.

In this study, we observed that the photoluminescence (PL) intensity of ZnO/Ag nanogratings was significantly enhanced compared with that of a planar counterpart under illumination of both transverse magnetic (TM) and transverse electric (TE)-mode light. In the TM mode,...

Encapsulation of Mitoxantrone within Cucurbit[8]uril Decreases Toxicity and Enhances Survival in a Mouse Model of Cancer.

ACS medicinal chemistry letters

Konda SK, Maliki R, McGrath S, Parker BS, Robinson T, Spurling A, Cheong A, Lock P, Pigram PJ, Phillips DR, Wallace L, Day AI, Collins JG, Cutts SM.
PMID: 28523107
ACS Med Chem Lett. 2017 Apr 24;8(5):538-542. doi: 10.1021/acsmedchemlett.7b00090. eCollection 2017 May 11.

Mitoxantrone was efficiently encapsulated within cucurbit[8]uril in a 2:1 complex where the two mitoxantrone molecules were symmetrically located through both portals of a cucurbit[8]uril cage. The novel complex facilitates increased mitoxantrone uptake in mouse breast cancer cells and decreases...
