Turbidimetric Determination of Fecal Calprotectin Using Two Table Top Chemistry Analyzers: Mindray BS-200E and Cobas® c111.

Background: Fecal calprotectin assays are widely used in diagnosis and monitoring of inflammatory bowel disease (IBD) in patients with suspected IBD. The most frequently used technique is ELISA and microtiter plates. Turbidimetric assays for analysis of fecal calprotectin can significantly reduce turnaround time.

The role of interleukin-6 in lipopolysaccharide-induced fever by mechanisms independent of prostaglandin E2.

Fever has been shown to be elicited by prostaglandin E(2) (PGE(2)) binding to its receptors on thermoregulatory neurons in the anterior hypothalamus. The signals that trigger PGE(2) production are thought to include proinflammatory cytokines, such as IL-6. However, although the presence of IL-6 is critical for fever, IL-6 by itself is not or only weakly pyrogenic.
