Quantitative PCR (qPCR) using real-time detection of amplification is limited to a small number of targets within a single reaction. The ICEPlex system, using our scalable target analysis routine (STAR) technology, was developed to provide an automated, high multiplexing PCR solution. ICEPlex combines PCR thermal cycling with dynamic, sequential amplicon separation by capillary electrophoresis and two-color quantitative detection in a single integrated system. In contrast to probe-based qPCR, ICEPlex directly measures amplicon accumulation through incorporation of labeled primers. Three orders of magnitude of optical detection range and at least 7 logs of detectable target concentration range are demonstrated. The system can separate more than 50 amplicons per color channel, ranging from 100 to 500 bases, providing broad multiplexing capabilities for a wide spectrum of nucleic acid amplification applications. ICEPlex can be used for analysis of viral DNA or RNA targets, detection of genetic variants, and for reverse-transcriptase PCR gene expression panels.

Background: Heart failure (HF) is a chronic, progressive condition where the heart cannot pump enough blood to meet the body's needs. In addition to the daily challenges that HF poses, acute exacerbations can lead to costly hospitalizations and increased mortality. High health care costs and the burden of HF have led to the emerging application of new technologies to support people living with HF to stay well while living in the community.

Electroencephalographic signals are obtained by amplifying and recording the brain's spontaneous biological potential using electrodes positioned on the scalp. While proven to help find changes in brain activity with a high temporal resolution, such signals are contaminated by non-stationary and frequent artefacts. A plethora of noise reduction techniques have been developed, achieving remarkable performance.

Background: Mental health remains among the top 10 leading causes of disease burden globally, and there is a significant treatment gap due to limited resources, stigma, limited accessibility, and low perceived need for treatment. Problem Management Plus, a World Health Organization-endorsed brief psychological intervention for mental health disorders, has been shown to be effective and cost-effective in various countries globally but faces implementation challenges, such as quality control in training, supervision, and delivery. While digital technologies to foster mental health care have the potential to close treatment gaps and address the issues of quality control, their development requires context-specific, interdisciplinary, and participatory approaches to enhance impact and acceptance.

Background: With the expiration of patents for multiple biotherapeutics, biosimilars are gaining traction globally as cost-effective alternatives to the original products. Glycosylation, a critical quality attribute, makes glycosimilarity assessment pivotal for biosimilar development. Given the complexity of glycoanalytical profiles, assessing glycosimilarity is nontrivial.

Purpose: Alternative non-standard paediatric visual field (VF) tests have been developed to address the challenges associated with standard approaches. However, diagnostic accuracy of these new VF tests has not yet been rigorously evaluated. This systematic review aims to explore diagnostic accuracy and feasibility of non-standard VF tests in paediatric patients.
