PURPOSE: The aim of this study was to evaluate the cytotoxic effect of a novel nano-silver particle (25.2±6.5 nm) endodontic irrigant (0.2 mM) and compare it with 3% sodium hypochlorite.MATERIALS AND METHODS: Two cell types, mouse fibroblast National Institutes...

Allograft dysfunction in a patient with an odd-looking kidney: case of renal lipomatosis and review of literature.

Clinical kidney journal

Posadas MA, Chua E, Thomas B, Savage SJ, Baliga P.
PMID: 25874099
Clin Kidney J. 2012 Aug;5(4):359-61. doi: 10.1093/ckj/sfs083.

Renal lipomatosis was diagnosed in a kidney transplant recipient who presented with acute kidney injury (AKI) several years after transplantation. The patient had an odd-looking kidney transplant on ultrasound and computed tomography (CT) scan, showing a medullary mass with...

Using a new fabrication strategy, novel, self-enclosed microporous silicalite-1 zeolite microtunnel and microchunnel architectures were successfully prepared.

Conditional statistics of temperature fluctuations in turbulent convection.

Physical review. E, Statistical, nonlinear, and soft matter physics

Ching ES, Chau KL.
PMID: 11308985
Phys Rev E Stat Nonlin Soft Matter Phys. 2001 Apr;63(4):047303. doi: 10.1103/PhysRevE.63.047303. Epub 2001 Mar 28.

We find that the conditional statistics of temperature difference at fixed values of the locally averaged temperature dissipation rate in turbulent convection become Gaussian in the regime where the mixing dynamics is expected to be driven by buoyancy. Hence,...

Discovery of indium complexes as water-tolerant Lewis acids.

Chemical communications (Cambridge, England)

Loh TP, Chua GL.
PMID: 17009450
Chem Commun (Camb). 2006 Jul 14;(26):2739-49. doi: 10.1039/b600568n.

The work on development of organic reactions that are tolerant to air and moisture, especially that of carbon-carbon bond forming reactions, had only started in the early 1990s. Our laboratory had approached this subject when it was still in...

Cobalt-catalyzed N-arylation of nitrogen nucleophiles in water.

Chemistry (Weinheim an der Bergstrasse, Germany)

Teo YC, Chua GL.
PMID: 19219864
Chemistry. 2009;15(13):3072-5. doi: 10.1002/chem.200802483.

Cobalt 'n' cross-coupling! A facile and practical strategy catalyzed by CoCl(2)6 H(2)O has been developed for the N-arylation of nitrogen nucleophiles with substituted aryl halides in water. The protocol is very simple and requires only mild conditions. A variety...

Role of delta-hole-doped interfaces at Ohmic contacts to organic semiconductors.

Physical review letters

Zhou M, Chua LL, Png RQ, Yong CK, Sivaramakrishnan S, Chia PJ, Wee AT, Friend RH, Ho PK.

An electromodulated absorption spectroscopy study of the contact between an organic semiconductor (OSC) poly(2,5-dialkoxy-p-phenylenevinylene) and p-doped poly(3,4-ethylenedioxythiophene) electrodes of different work functions (phivac) reveals direct evidence for the formation of a hole-doped layer at the OSC interface in equilibrium...

Compound C prevents Hypoxia-Inducible Factor-1α protein stabilization by regulating the cellular oxygen availability via interaction with Mitochondrial Complex I.

BMC research notes

Chua YL, Hagen T.
PMID: 21481276
BMC Res Notes. 2011 Apr 12;4:117. doi: 10.1186/1756-0500-4-117.

The transcription factor Hypoxia-Inducible Factor-1α is a master regulator of the cellular response to low oxygen concentration. Compound C, an inhibitor of AMP-activated kinase, has been reported to inhibit hypoxia dependent Hypoxia-Inducible Factor-1α activation via a mechanism that is...
