Elevated cell-free hemoglobin: A novel early biomarker following traumatic injury.

Background: Cell-free hemoglobin (CFH) and free heme are potent mediators of endotheliopathy and organ injury in sepsis, but their roles in other hemolytic pathologies are not well-defined. A prime example is trauma where early hemolysis may initiate damage and predict outcome. Here, we investigated the presence of plasma CFH, heme, and their major scavengers after traumatic injury.

Using microfluidic shear to assess transfusion requirements in trauma patients.

Background: Viscoelastic assays have widely been used for evaluating coagulopathies but lack the addition of shear stress important to clot formation. Stasys technology subjects whole blood to shear forces over factor-coated surfaces. Microclot formation is analyzed to determine clot area (CA) and platelet contractile forces (PCFs).

Targeted Transcriptomic Analysis of C57BL/6 and BALB/c Mice During Progressive Chronic Infection Reveals Changes in Host and Parasite Gene Expression Relating to Neuropathology and Resolution.

is a resilient parasite that infects a multitude of warm-blooded hosts and results in a lifelong chronic infection requiring continuous responses by the host. Chronic infection is characterized by a balanced immune response and neuropathology that are driven by changes in gene expression. Previous research pertaining to these processes has been conducted in various mouse models, and much knowledge of infection-induced gene expression changes has been acquired through the use of high throughput sequencing techniques in different mouse strains and post-mortem human studies.
