Fast, accurate urine test for pneumonia possible, study finds

Researchers at UC Davis have developed a fast and accurate urine test for pneumonia using nuclear magnetic resonance spectroscopy. The test identifies a unique chemical 'fingerprint' in the urine of patients infected with Streptococcus pneumoniae, distinguishing it from other types of pneumonia and noninfectious lung diseases.

Most antidepressants miss key target of clinical depression

A new study reveals that most antidepressants miss the mark on a key brain protein called monoamine oxidase A (MAO-A), which is highly elevated during clinical depression. This finding has important implications for understanding why antidepressants don't always work, with potential benefits for developing more effective treatments.
