Protein and transcriptional biomarker profiling may inform treatment strategies in lower respiratory tract infections by indicating bacterial–viral differentiation

Microbiology Spectrum
Lower respiratory tract infections (LRTIs) remain a significant global cause of infectious disease-related mortality. Accurate discrimination between acute bacterial and viral LRTIs is crucial for optimal patient care, prevention of unnecessary ...

Operational considerations for approximating molecular assembly by Fourier transform mass spectrometry

Frontiers in Astronomy and Space Sciences
Some of the most common life detection techniques for planetary exploration focus on organic molecule characterization, but life on other planets may not chemically resemble that found on Earth.
