Hepatocellular carcinoma (HCC) surveillance lacks a reliable biomarker. Alpha-fetoprotein (AFP) is the most widely used. However, not all HCCs secrete AFP. AFP may be elevated with cirrhosis in the absence of HCC. Serum alpha-l-fucosidase (AFU) and squamous cell carcinoma antigen-immunoglobulin M complex (SCCA-IgM) were found to be useful markers in(More)
Passive Infra-Red (PIR) sensor is one of many detection sensors used to detect any intrusion process in the nuclear sites. In this work, an estimation of a PIR sensor's probability of detection for a hypothetical nuclear facility is presented. Sensor performance testing performed to determine whether a particular sensor will be acceptable in a proposed(More)
Vitamin D is getting more attention everyday due to its importance in maintaining bone and calcium homeostasis, cellular proliferation, differentiation and immune response. Vitamin D is derived from diet or elicited in the skin by the activation of 7-dehydrocholesterol, which is an inert molecule that must be activated by ultraviolet light to form(More)
Given the elevated risk of cardiovascular events and the higher prevalence of silent ischaemia in diabetic patients, it is important to screen those patients for cardiac autonomic neuropathy (CAN). Early detection of CAN in diabetic patients, and hence timely intervention, are of critical importance towards preventing sudden cardiac death. The aim of this(More)
