Insufficiency of BUBR1, a mitotic spindle checkpoint regulator, causes impaired ciliogenesis in vertebrates (2011)
Journal Article

Budding uninhibited by benzimidazole-related 1 (BUBR1) is a central molecule of the spindle assembly checkpoint. Germline mutations in the budding uninhibited by benzimidazoles 1 homolog beta gene encoding BUBR1 cause premature chromatid separation (...

The overshoot phenomenon as a function of internal resistance in microbial fuel cells (2011)
Journal Article

A method for assessing the performance of microbial fuel cells (MFCs) is the polarisation sweep where different external resistances are applied at set intervals (sample rates). The resulting power curves often exhibit an overshoot where both power a... Read More about The overshoot phenomenon as a function of internal resistance in microbial fuel cells.

Factors affecting estrogen receptor status in a multiracial Asian country: An analysis of 3557 cases (2011)

Computational modalities of Belousov-Zhabotinsky encapsulated vesicles (2011)
Journal Article

We present both simulated and partial empirical evidences for the computational utility of many connected vesicle analogues of an encapsulated nonlinear chemical processing medium. By connecting small vesicles containing a solution of sub-excitable B... Read More about Computational modalities of Belousov-Zhabotinsky encapsulated vesicles.

The actin-bundling protein Fascin is overexpressed in inflammatory bowel disease and may be important in tissue repair (2011)
Journal Article

Background: Fascin is associated with increased cell motility in colorectal tumours but is absent from the normal colonic epithelium. We examined the expression of fascin in inflammatory bowel disease (IBD) and its location at regions undergoing rest...

Herpetological surveys of forest fragments between Montagne d’Ambre National Park and Ankarana Special Reserve, Northern Madagascar (2011)
Journal Article

Despite Madagascar being well known for its unique biodiversity and high levels of endemism, its herpetofauna remains understudied, especially outside protected areas. Here, we surveyed the herpetofauna within the fragmented dry deciduous forests of...

Towards arithmetic circuits in sub-excitable chemical media (2011)
Journal Article

A sub-excitable Belousov-Zhabotinsky medium exhibits localized travelling excitations (in contrast to an excitable medium exhibiting target or spiral waves). Initially assymetric perturbations give birth to excitation wave-fragments. The shape and ve... Read More about Towards arithmetic circuits in sub-excitable chemical media.

A screen-printed, amperometric biosensor array incorporated into a novel automated system for the simultaneous determination of organophosphate pesticides (2011)
Journal Article

Organophosphate pesticides present serious risks to human and environmental health. A rapid reliable, economical and portable analytical system will be of great benefit in the detection and prevention of contamination. A biosensor array based on six...

Development of a fluorescent method for detecting the onset of coagulation in human plasma on microstructured lateral flow platforms (2011)
Journal Article

Microfluidic devices and microsystems have been used to develop blood coagulation monitoring devices for point of care diagnostic use. However, many of them suffer from inherent variability and imprecision, partly due to the fact that they only detec...

Enhanced electrochemical reduction of hydrogen peroxide on silver paste electrodes modified with surfactant and salt (2011)
Journal Article

The modification of silver paste electrodes with a combination of dodecylbenzenesulfonic acid and KCl has been shown to lead to significant enhancements of the electrochemical reduction of hydrogen peroxide. The catalytic enhancement was shown to be... Read More about Enhanced electrochemical reduction of hydrogen peroxide on silver paste electrodes modified with surfactant and salt.

Impact of land management practices on high-affinity methanotrophic bacterial populations: Evidence from long-term sites at Rothamsted (2011)
Journal Article

The impacts of land-use change and long-term agricultural practices on the bacterial and methanotrophic biomass in the soils comprising the Classical Experiments at Rothamsted Research were investigated by using 13CH 4 phospholipid fatty acid stable...
