Acoustical-molecular techniques for magnetic resonance imaging
… attain sensitivity to new classes of indicators. Molecular imaging with targeted injectable contrast agents and MR elastography with externally delivered acoustic vibrations are two such advancements with increasing clinical significance. Conventionally employed separately, this work explores how …

Implementation of molecular techniques in the diagnosis of legionnaires’ disease and in the investigation of legionella outbreaks
… available for up to 65% patients, alternative techniques are needed to diagnose LD and maximise the amount of typing data that can be obtained to aid investigations. Urinary antigen detection and serology provide very limited information regarding the infecting strain, while the advent of PCR …

Cell-free fetal DNA (cffDNA) enrichment for non-invasive prenatal testing (NIPT): a comparison of molecular techniques
Prenatal assessment of fetal health is routinely offered throughout pregnancy to ensure that the most effective management can be provided to maintain fetal and maternal well-being. Currently, invasive testing is used for definitive diagnosis of fetal aneuploidy, which is associated with a 1% risk …

The application of molecular techniques for the rapid and sensitive detection of gastrointestinal pathogens directly in food
… to meet the demands for rapid food testing. Molecular methods, such as PCR, offer a rapid, sensitive and specific means of detecting pathogens, however loss of sensitivity and lack of robustness have been reported when PCR is applied to heterogeneous and complex food matrices. The aim of this …

Aetiology of pleural effusions diagnosed by routine culture and molecular techniques in children living in a high tuberculosis-endemic setting
BACKGROUND: Confirming aetiology of pleural effusion in children may be difficult in tuberculosis (TB)-endemic settings. We investigated the role of polymerase chain reaction (PCR) and routine biochemical tests in discriminating pleural effusion caused by bacteria from other aetiologies. METHODS: …
