Background: Diagnostic test evaluation requires a reference standard. We describe an approach for creating a reference standard for acute infection using unrestricted adjudication and apply it to compare biomarker tools.

Methods: Adults and children with suspected acute infection enrolled in three prospective studies at emergency departments and urgent cares were included.

Selective catalytic oxidation (SCO) of NH to N is one of the most effective methods used to eliminate NH emissions. However, achieving high conversion over a wide operating temperature range while avoiding over-oxidation to NO remains a significant challenge. Here, we report a bi-metallic surficial catalyst (PtCuO/AlO) with improved Pt atom efficiency that overcomes the limitations of current catalysts.

Autophagy plays a crucial role in the host response to Mycobacterium tuberculosis (Mtb) infection, yet the dynamics and regulation of autophagy induction on Mtb-containing vacuoles (MCVs) remain only partially understood. We employed time-lapse confocal microscopy to investigate the recruitment of LC3B (LC3), a key autophagy marker, to MCVs at the single cell level with our newly developed workflow for single cell and single MCV tracking and fluorescence quantification. We show that approximately 70% of MCVs exhibited LC3 recruitment but that was lost in about 40% of those MCVs.

Background: Back pain is increasingly common, leading to more spine surgeries. While most people experience pain relief and improved function after surgery, many continue to suffer from chronic post-surgical pain (CPSP) with limited functional improvement. CPSP is often treated with opioids, raising concerns about misuse, poor functional outcomes, and broader public health impacts.
