Gravitational collapse of depletion-induced colloidal gels.

Soft matter

Harich R, Blythe TW, Hermes M, Zaccarelli E, Sederman AJ, Gladden LF, Poon WC.
PMID: 27001686
Soft Matter. 2016 May 11;12(19):4300-8. doi: 10.1039/c5sm02651b.

We study the ageing and ultimate gravitational collapse of colloidal gels in which the interparticle attraction is induced by non-adsorbing polymers via the depletion effect. The gels are formed through arrested spinodal decomposition, whereby the dense phase arrests into...

PMID: 26155298
J Breast Cancer. 2015 Jun;18(2):200-5. doi: 10.4048/jbc.2015.18.2.200. Epub 2015 Jun 26.

Primary inflammatory myofibroblastic tumors (IMTs) of the breast are uncommon and metastasis of IMTs is extremely rare. To date, the natural course of this disease is not fully understood. Although patients with IMTs should undergo regular follow-up after complete...

Comparison of Approaches in Estimating Interaction and Quadratic Effects of Latent Variables.

Multivariate behavioral research

Lee SY, Song XY, Poon WY.
PMID: 26759934
Multivariate Behav Res. 2004 Jan 01;39(1):37-67. doi: 10.1207/s15327906mbr3901_2.

Various approaches using the maximum likelihood (ML) option of the LISREL program and products of indicators have been proposed to analyze structural equation models with non-linear latent effects on the basis of Kenny and Judd's formulation. Recently, some methods...

Yang JF, Ding XF, Chen L, Mat WK, Xu MZ, Chen JF, Wang JM, Xu L, Poon WS, Kwong A, Leung GK, Tan TC, Yu CH, Ke YB, Xu XY, Ke XY, Ma RC, Chan JC, Wan WQ, Zhang LW, Kumar Y, Tsang SY, Li S, Wang HY, Xue H.
PMID: 25558350
J Clin Bioinforma. 2014 Dec 05;4(1):15. doi: 10.1186/s13336-014-0015-z. eCollection 2014.

BACKGROUND: AluScan combines inter-Alu PCR using multiple Alu-based primers with opposite orientations and next-generation sequencing to capture a huge number of Alu-proximal genomic sequences for investigation. Its requirement of only sub-microgram quantities of DNA facilitates the examination of large...

Inhibitor of caspase-activated DNase expression enhances caspase-activated DNase expression and inhibits oxidative stress-induced chromosome breaks at the mixed lineage leukaemia gene in nasopharyngeal carcinoma cells.

Cancer cell international

Boon SS, Sim SP.
PMID: 26019688
Cancer Cell Int. 2015 May 24;15:54. doi: 10.1186/s12935-015-0205-1. eCollection 2015.

BACKGROUND: Nasopharyngeal carcinoma (NPC) is commonly found in Asia, especially among the Chinese ethnic group. Chromosome rearrangements are common among NPC patients. Although the mechanism underlying the chromosome rearrangements in NPC is unclear, various mechanisms including activation of caspase-activated...

Large-Scale Proteomics of the Cassava Storage Root and Identification of a Target Gene to Reduce Postharvest Deterioration.

The Plant cell

Vanderschuren H, Nyaboga E, Poon JS, Baerenfaller K, Grossmann J, Hirsch-Hoffmann M, Kirchgessner N, Nanni P, Gruissem W.
PMID: 24876255
Plant Cell. 2014 May;26(5):1913-1924. doi: 10.1105/tpc.114.123927. Epub 2014 May 29.

Cassava (Manihot esculenta) is the most important root crop in the tropics, but rapid postharvest physiological deterioration (PPD) of the root is a major constraint to commercial cassava production. We established a reliable method for image-based PPD symptom quantification...
