Most cases of cardiac arrest during sport are likely to be preventable. In addition, the emergency response with cardiopulmonary resuscitation (CPR) and defibrillators within the sports context can be improved. This has been shown in a thesis from the University of Gothenburg.

Cell-to-cell communication through nanosized particles, working as messengers and carriers, can now be analyzed in a whole new way, thanks to a new method involving CRISPR gene-editing technology. The particles, known as small extracellular vesicles (sEVs), play an important role in the spread of disease and as potential drug carriers. The newly developed system, named CIBER, enables thousands of genes to be studied at once, by labeling sEVs with a kind of RNA “barcode.” With this, researchers hope to find what factors are involved in sEV release from host cells. This will help advance our understanding of basic sEV biology and may aid in the development of new treatments for diseases, such as cancer.
