The fabrication of mammalian cell-containing poly(ethylene glycol) (PEG) hydrogel microstructures on glass and silicon substrates is described. Using photoreaction injection molding in poly(dimethylsiloxane) microfluidic channels, three-dimensional hydrogel microstructures encapsulating cells (fibroblasts, hepatocytes, macrophage) were fabricated with cells uniformly distributed...

3-Mercapto-1-propanesulfonic acid and Bis(3-sulfopropyl) disulfide adsorbed on Au(111): in situ scanning tunneling microscopy and electrochemical studies.

3-Mercapto-1-propanesulfonic acid (MPS) and bis(3-sulfopropyl) disulfide (SPS) adsorbed on a Au(111) electrode were studied by using in situ scanning tunneling microscopy (STM). Although the adsorptions of MPS and SPS are known to be oxidative and reductive, respectively, on an...

pH-dependent electron transfer from re-bipyridyl complexes to metal oxide nanocrystalline thin films.

The journal of physical chemistry. B

She C, Anderson NA, Guo J, Liu F, Goh WH, Chen DT, Mohler DL, Tian ZQ, Hupp JT, Lian T.
PMID: 16853498
J Phys Chem B. 2005 Oct 20;109(41):19345-55. doi: 10.1021/jp053948u.

Photoinduced interfacial electron transfer (ET) from molecular adsorbates to semiconductor nanoparticles has been a subject of intense recent interest. Unlike intramolecular ET, the existence of a quasicontinuum of electronic states in the solid leads to a dependence of ET...

In situ STM revelation of the adsorption and polymerization of aniline on Au(111) electrode in perchloric acid and benzenesulfonic acid.

Langmuir : the ACS journal of surfaces and colloids

Lee Y, Chen S, Tu H, Yau S, Fan L, Yang Y, Dow WP.
PMID: 20050608
Langmuir. 2010 Apr 20;26(8):5576-82. doi: 10.1021/la903857x.

In situ scanning tunneling microscopy (STM) was used to study the adsorption and polymerization of aniline on Au(111) single-crystal electrode in 0.1 M perchloric acid and 0.1 M benzenesulfonic acids (BSA) containing 30 mM aniline, respectively. At the onset...

Enhancement of plasmacytoma cell growth by ascorbic acid is mediated via glucose 6-phosphate dehydrogenase.

Cancer research and treatment

Koh WS, Choi WH, Lee SJ, Park C, Park CH.
PMID: 19746226
Cancer Res Treat. 2007 Mar;39(1):22-9. doi: 10.4143/crt.2007.39.1.22. Epub 2007 Mar 31.

PURPOSE: We investigated the mechanism by which some types of cancer cells grow faster in the presence of ascorbic acid supplementation.MATERIALS AND METHODS: Adj.PC-5, a mouse plasmacytoma cell, is known to show ascorbic acid-dependent growth and was chosen as...

Revelation of the spatial structures and polymerization of aniline on Au(100) electrode by in situ scanning tunnelling microscopy.

Chemical communications (Cambridge, England)

Yau S, Lee Y, Chang C, Dow WP.
PMID: 19774253
Chem Commun (Camb). 2009 Oct 14;(38):5737-9. doi: 10.1039/b907189j. Epub 2009 Sep 02.

In situ STM imaging of Au(100) electrode in 1 M HClO4 + 0.03 M aniline revealed highly ordered aniline adlattices of (2 radical 2 x 4 radical 2)R45 degrees and (radical 10 x radical 10)R18 degrees and polyaniline molecules...

Spontaneous Pneumothorax in an Allogeneic Cell Transplant Recipient with Invasive Pulmonary Aspergillosis and Antecedent RSV Pneumonitis.

Mediterranean journal of hematology and infectious diseases

Koh LP, Poon ML, Tam JK, Teo L, Hsu LY.
PMID: 21625303
Mediterr J Hematol Infect Dis. 2011;3(1):e20110. doi: 10.4084/mjhid.2011.014. Epub 2011 Apr 01.

We report a case of invasive pulmonary aspergillosis (IPA) following respiratory syncytial virus infection in an allogeneic hematopoietic stem cell transplant (HSCT) recipient with chronic graft-versus-host disease. Delayed diagnosis of IPA resulted in the development of a pneumothorax, a...
