42 Million Protein Molecules In A Simple Cell; Scientists Reveal

Researchers from the University of Toronto's Donnelly Centre for Cellular and Biomolecular Research, they revealed that there are some 42 million protein molecules in a simple cell. Analyzing data from almost two dozen large studies of protein abundance in yeast cells, the team could produce for the first-time reliable estimates for the number of molecules for each protein. The study published in the journal Cell Systems.

FDG PET: Improve Treatment Selection for Patients with Advanced NSCLC

Italian researches have demonstrated a better way of determining the aggressiveness of tumors in patients with advanced non-small cell lung cancer (NSCLC). The study was published in The Journal of Nuclear Medicine, researchers used 18F-fluorodeoxyglucose (FDG) PET/CT imaging to show that the amount of cell-free tumor DNA circulating in the bloodstream correlates with tumor metabolism (linked to cancer aggressiveness), not tumor burden (amount of cancer in the body).
