A new study from the University of Helsinki shows that cells that are freshly isolated from lung cancers can be used to create robust drug response data. This approach can identify actionable or non-responsive treatments, illustrated by a case study in which the assay was used to guide the compassionate treatment of a patient.
The risk of colorectal cancer can be predicted more accurately by determining seven blood-based micro-RNAs (miRNAs) than by using traditional methods - and can be done so many years before a diagnosis is made. In a current study, researchers from the German Cancer Research Center and the National Center for Tumor Diseases (NCT) Heidelberg show that miRNA profiles provide greater predictive…
Researchers at Karolinska Institutet recently reported that magnetic resonance imaging (MRI) could reduce overdiagnoses and thereby improve prostate cancer screening. Now, the same research group has published a study in The Lancet Oncology, which shows that the addition of a novel blood test, the Stockholm3 test, can reduce the number of MRIs performed by a third while further preventing the…
Covid-19 disease severity is determined by the individual patient’s immune response. The precise mechanisms taking place inside the lungs and blood during the early phase of the disease, however, remain unclear. Researchers from Charité – Universitätsmedizin Berlin, the Max Delbrück Center for Molecular Medicine (MDC) and Freie Universität Berlin have now studied the cellular mechanisms…
A novel study published in AACC’s The Journal of Applied Laboratory Medicine shows that delaying the second Covid-19 vaccine dose for more than the recommended 3-4 weeks results in higher antibody levels. This finding could play a vital role in shaping vaccine distribution strategies that increase access to the vaccine around the globe.
Home test kits to check for Covid-19 spike proteins and anti-Covid-19 antibodies are fast and simple to use but lack the sensitivity and accuracy of laboratory tests. Researchers from Eindhoven University of Technology with Utrecht University have developed a new type of sensor that combines the sensitivity and accuracy of current laboratory-based measurements with the speed and low-cost of…
Cancer informatics and digital pathology provider Inspirata announced that King’s Health Partners ECMC and Guy’s and St Thomas’ NHS Foundation Trust will pilot its Trial Navigator software as part of an evaluation the organisations are conducting into how artificial intelligence based automation can improve the identification and efficiency of matching patients with cancer to early phase…
Antibiotic-resistant pathogens have become one of the greatest threats to public health. The basic mechanisms of resistance evolution have been well studied experimentally and are an important research field at Kiel University. An important factor in this context, but one that has received little attention so far, is the population size of the respective pathogen. Over the course of an infection…
Molecular pathology company Xyall BV launches its Tissector High Throughput (HT) system for precision diagnostics. This is a world first – enabling high volume, molecular diagnostic laboratories to capitalize commercially on the company’s automated tissue dissection technology.
Markers in our blood – ‘fingerprints’ of infection – could help identify individuals who have been infected by SARS-CoV-2, the coronavirus that causes Covid-19, several months after infection even if the individual had only mild symptoms or showed no symptoms at all, say Cambridge researchers. The team has received funding from the National Institute for Health Research to develop a test…
The Lausanne University Hospital (CHUV) and EPFL teamed up to develop a new test that’s sensitive enough to measure the amount of SARS-CoV-2 neutralizing antibodies present in the bloodstream. The scientists’ discovery, published in Science Translational Medicine, opens promising new avenues for tracking immunity acquired by infection or vaccination.
A researcher at the Technical University of Denmark (DTU) has developed a mathematical model for use in automated image analysis of tissue samples. The model provides the possibility for better and more similar cancer prognosis and treatment.
Life science research and clinical diagnostics company Bio-Rad Laboratories announced the launch of its PREvalence ddPCR SARS-CoV-2 Wastewater Quantification Kit, a tool to detect the virus that causes Covid-19 in a community’s wastewater. "With wastewater testing becoming more widely adopted, this assay provides the ability for a community to determine if the virus is present days to…
In a collaboration with the Faculty of Statistics at TU Dortmund and the University Medical Center in Mainz, a research team at the Leibniz Research Centre for Working Environment and Human Factors in Dortmund (IfADo) has developed a test that can be used to predict the success of therapy for breast cancer. Breast cancer is one of the most common tumour diseases worldwide. One in eight women will…

The partnership links specimen handling, nucleic acid extraction, assay set-up, amplification, and results reporting in a seamless integration of the companies technologies. “This partnership capitalises…
Rapid tests effectively broke Covid-19 infection chains in spring 2021. This is shown by a model developed by researchers of the ECONtribute: Markets & Public Policy Cluster of Excellence of the Universities of Bonn and Cologne, the Collaborative Research Center Transregio 224 EPoS of the Universities of Bonn and Mannheim, and the Institute for the Study of Labor (IZA). According to the…
Integrating laboratory functions on a microchip circuit is helping improve the cost-effectiveness of drug development. So-called ‘lab-on-a-chip’ or ‘human-on-a-chip’ technology can highlight which treatments may, or may not, work before advancing along the clinical trial process. It can also have benefits for chronic and rare diseases, as well as helping shape personalised medicine.…
An international research team from Saudi Arabia, Germany, and Jordan has developed a novel pathogen aptasensor swab designed to qualitatively detect, within five minutes, any methicillin-resistant Staphylococcus aureus (MRSA) contamination that remains in a hospital isolation room or other surface following standard decontamination and cleaning.
When patients are admitted to a hospital emergency room (ER) it is immediately vital to determine whether s/he has Covid-19. However, with a regular PCR test a result can take up to a few hours. Thus, initially, the patient must be isolated. During the height of the corona pandemic last year, researcher Ruben Deneer from Eindhoven University of Technology (TU/e) and clinical chemist Arjen-Kars…
Blood cultures are important laboratory tests to diagnose serious infections. Contamination is a constant concern – a patient could be misdiagnosed due to a false-positive test. Initial specimen diversion (ISD) could radically change this.
We recently had the pleasure of interviewing Dr. Peter Riegman from Erasmus University. Dr. Riegman is a Molecular Biologist and head of the Erasmus MC Tissue Bank. As an early adopter of digital pathology, Dr. Riegman purchased his first Hamamatsu Photonics whole slide scanner in 2005. It was a NanoZoomer HT, one of Hamamatsu’s very first production units, and it is still in daily use at…
When viruses infect cells, changes in the cell nucleus occur, and these can be observed through fluorescence microscopy. Using fluoresence images from live cells, researchers at the University of Zurich have trained an artificial neural network to reliably recognize cells that are infected by adenoviruses or herpes viruses. The procedure also identifies severe acute infections at an early stage.
The idea of visiting the doctor’s office with symptoms of an illness and leaving with a scientifically confirmed diagnosis is much closer to reality because of new technology developed by researchers at McMaster University. Engineering, biochemistry and medical researchers from across campus have combined their skills to create a hand-held rapid test for bacterial infections that can produce…
Final results from a study of a blood test that can detect more than 50 types of cancer have shown that it is accurate enough to be rolled out as a multi-cancer screening test among people at higher risk of the disease, including patients aged 50 years or older, without symptoms. In a paper published in the cancer journal Annals of Oncology, researchers report that the test accurately detected…
