PEAR: setting nano-imaging in motion

Ever since the Abbe diffraction limit of conventional microscopy has been surpassed, super-resolution techniques have been diving ever deeper into the most miniscule details of molecular structures. We spoke with Prof. Dominic Zerulla, whose company PEARlabs is developing an imaging technique that sets out to push the boundaries once more – by looking at in-vivo nano-scale processes in motion.

Ion mobility spectrometry: Rapid results from breath analysis

Ion-mobility spectrometry (IMS) offers opportunities for rapid diagnosis and clinical decision-making due to breath analysis. As a rapid separation tool, it has clinical value in the identification and analysis of proteins, peptides, lipids, and glycans. The tool is already used as an exhaled drug monitor for anaesthetised patients. It is flexible, portable and has use for point-of-care testing,…

How staphylococci protect themselves against antibiotics

The skin bacterium Staphylococcus aureus often develops antibiotic resistance. It can then cause infections that are difficult to treat. Researchers at the University of Bonn have uncovered an ingenious way in which a certain strain of Staphylococcus aureus protects itself against the important antibiotic vancomycin. The results have now been published in the journal Microbiology Spectrum.

Researchers find warning signs for dementia in the blood

Researchers at the DZNE and the University Medical Center Göttingen (UMG) have identified molecules in the blood that can indicate impending dementia. Their findings, which are presented in the scientific journal “EMBO Molecular Medicine”, are based on human studies and laboratory experiments. Various university hospitals across Germany were also involved in the investigations.

Article • Mass spectrometry goes handheld

A pen to pin down the fringes of cancer

Mass spectrometry – a powerful tool for analysing the molecular composition of a tissue sample – is invaluable during cancer surgery. However, mass spectrometers are complex and unwieldy, and certainly a poor fit for an operating room (OR). To create a bridge between the lab and OR, Professor Livia S Eberlin, from Baylor College of Medicine, has developed a very special ‘pen’.

Pancreatic cancer ‘priming’ may make chemotherapy more effective

A new approach to ‘prime’ the tumour environment may improve how effective chemotherapy is for pancreatic ductal adenocarcinoma, one of the most aggressive forms of pancreatic cancer. In preclinical models, a team at the Garvan Institute of Medical Research could enhance the tumours’ response to chemotherapy by reducing the stiffness and density of the connective tissue known as the stroma,…

Antidepressants show promise in cancer growth inhibition

Classic antidepressants could help improve modern cancer treatments. They slowed the growth of pancreatic and colon cancers in mice, and when combined with immunotherapy, they even stopped the cancer growth long-term. In some cases the tumors disappeared completely, researchers at the University of Zurich (UZH) and University Hospital Zurich (USZ) have found. Their findings will now be tested in…

Speeding up diagnostics to detect antibiotic resistance

Infectious disease diagnostics are notoriously slow. The gold standard for laboratory diagnosis of bacterial and fungal infection involves growing the pathogen from a clinical specimen – an overnight event, or even longer. The healthcare focus is on improving the use of antibiotics for better patient outcomes and reducing the environmental pressures that drive antibiotic resistance. To impact…
