Metabolic regulation of the tumour and its microenvironment: The role of Epstein-Barr virus

Published in International Journal of Cancer, 2024

This is the first review paper that examines the links between Epstein-Barr virus, tumour metabolism and its microenvironment. Our review highlights how targeting this link may overcome resistance to immunotherapies.

Negative Index Metamaterial-Based Frequency-Reconfigurable Textile CPW Antenna for Microwave Imaging of Breast Cancer

Published in Sensors, 2022

This study reports the design and development of a metamaterial-based reconfigurable textile antenna for microwave breast imaging. This microwave imaging system was capable of detecting a tumour as small as 10 mm in a breast phantom and we propose that it may be used clinically for detection of breast cancer.

Self-reported symptom study of COVID-19 chemosensory dysfunction in Malaysia

Published in Scientific Reports, 2022

This is a nationwide, multi-centre, cross-sectional study of self-reported chemosensory dysfunction of 498 adult COVID-19 patients in Malaysia between June to November 2020 during the COVID-19 pandemic. By combining epidemiological and machine learning analyses, our study found that chemosensory dysfunction in COVID-19 was more widespread that previously reported among Asians and may be related to the infectivity of viral strains.

Clinical characteristics and predictors of mortality in patients with melioidosis: the Kapit experience

Published in Tropical Medicine & International Health, 2021

This is a retrospective study of 73 patients with melioidosis at Kapit Hospital, Sarawak, Malaysia between 2016 to 2019. Patients commonly presented with septic shock, in the form of bacteraemia and pneumonia. Two routine clinical parameters, serum bicarbonate and albumin were found to have important prognostic implications in septicaemic melioidosis..

Comparing the Utility and Surgical Outcomes of Harmonic Focus Ultrasonic Scalpel with Ligasure Small Jaw Bipolar Device in Thyroidectomies: A Prospective Randomized Controlled Trial

Published in Annals of Surgical Oncology, 2019

This is a randomized controlled trial comparing the use of Harmonic Focus ultrasonic scalpel and Ligasure Small Jaw bipolar device in thyroidectomy at a single tertiary center. There were significant differences in duration of surgery, postoperative drainage or adverse events. The Harmonic scalpel was associated with a higher postoperative pain but favoured by surgeons due to the ability to perform fine dissection with the device itself.

Carbonic anhydrase IX is a pH-stat that sets an acidic tumour extracellular pH in vivo

Published in British Journal of Cancer, 2018

This pre-clinical study, which forms part of my PhD thesis, is the first to demonstrate that a hypoxia-associated tumour enzyme, carbonic anhydrase IX (CAIX) acidifies the tumor microenvironment in vivo. This study also uncovered a extracellular pH-stat mechanism for CAIX that maintains a more acidic environment within solid tumors.

Carbonic Anhydrase Activity Monitored In Vivo by Hyperpolarized 13C-Magnetic Resonance Spectroscopy Demonstrates Its Importance for pH Regulation in Tumors

Published in Cancer Research, 2015

This is a pre-clinical study measuring the in vivo functional activity of Carbonic Anhydrase IX (CAIX) in colorectal tumor models with hyperpolarized H13CO2 using 13C magnetic resonance spectroscopy magnetization transfer measurements. Paradoxically, tumors overexpressing CAIX showed lower enzyme activity using magnetization transfer measurements, which could be explained by the more acidic tumour extracellular pH in these tumors and the decreased activity of CAIX at low pH.
