The Associations between Dietary Practices and Dietary Quality, Biological Health Indicators, Perceived Stress, Religiosity, Culture, and Gender in Multi-Cultural Singapore

Published date : 29 Jul 2018

Dietary quality, biological health, culture, religiosity, and perceived stress are co-related. However, there is a dearth of research conducted on Asian populations in secularized and harmonious multi-cultural societies. This study addresses these gaps by conducting an investigation in the multi-cultural and multi-religious Singapore to examine the parameters of culture and gender and the associations with 1) dietary quality, 2) biological health indicators, 3) religiosity, and perceived stress.

Effect of VH–VL Families in Pertuzumab and Trastuzumab Recombinant Production, Her2 and FcγIIA Binding

Published date : 14 Mar 2018

Many therapeutic antibodies are humanized from animal sources. In the humanization process, complementarity determining region grafting is tedious and highly prone to failure. With seven known VH families, and up to six known κ VL families, there are choices aplenty. However, the functions of these families remain largely enigmatic. To study the role of these V-region families, we made 84 recombinant combinations of the various VH and VL family whole IgG1 variants of both Trastuzumab and Pertuzumab.

The effects of Antibody Engineering CH and CL in Trastuzumab and Pertuzumab recombinant models: Impact on antibody production and antigen-binding

Published date : 15 Jan 2018

Current therapeutic antibodies such as Trastuzumab, are typically of the blood circulatory IgG1 class (Cκ/ CHγ1). Due to the binding to Her2 also present on normal cell surfaces, side effects such as cardiac failure can sometimes be associated with such targeted therapy. Using antibody isotype swapping, it may be possible to reduce systemic circulation through increased tissue localization, thereby minimising unwanted side effects. However, the effects of such modifications have yet to be fully characterized, particularly with regards to their biophysical properties in antigen binding.

APD SpectBT: Arduino-based mobile vis-Spectrophotometer

Published date : 14 Mar 2017

Quantification of samples is an integral step in numerous biological and chemical experiments. Spectrophotometers are often used together with colorimetric assays that react with the compound of interest in the samples. However, spectrophotometers are often costly, bulky and immobile. To increase the convenience and ease the process of spectrophotometry, the APD SpectBT was developed using the Arduino-based platform to create a smartphone dependent mobile spectrophotometer.

APD Colony Counter App: Using Watershed Algorithm for improved colony counting

Published date : 09 Aug 2016

The counting of colonies to quantitate bacteria is an important process in labs for research, clinical diagnosis, and environmental monitoring e.g. in water. Generally counted manually, progress in technology has automated the process through colony counters that can be purchased but can be costly. While efficient, there remains also a challenge correctly detecting clustered colonies compromising inaccurate counts. Leveraging on the smartphone camera, we developed an app that processes images of colony plates and automatically counts them.
