Free light chains are proteins produced by B lymphocytes during the process of antibody synthesis. Their production, as a reflection of B cell activation, can give insight into the activity of the adaptive immune system. In recent years, an automated immunoassay that provides quantitative measurement of free light chains in the serum has been developed. This assay has not only revolutionised the investigation of monoclonal light chain overproduction in plasma cell diseases, but has also allowed for the quantification of polyclonal free light chains in serum. The discovery of high levels of polyclonal free light chains in a number of inflammatory and auto-immune conditions has led to the examination of their value as a biomarker of disease activity. Research into their bio-activity has also highlighted their potential role in the pathogenesis of inflammatory disease, making them an attractive target for novel therapies.

Heat-stress-induced oxidative and inflammatory responses were important factors contributing to chicken intestinal damage. The purpose of this study was based on the antioxidant and anti-inflammatory activities of Physalis Calyx seu Fructus (Jin Deng Long, JDL) to investigate its efficacy and mechanism in relieving chicken heat stress damage. Primary chicken embryo duodenum cells and 90 30-day-old specific-pathogen-free chicken were randomly divided into control and JDL groups to establish heat stress models and .

Background: The pathogenesis of chronic obstructive pulmonary disease (COPD) is not fully understood. This work aimed to demonstrate the role of serum free light chains (sFLC) in the pulmonary inflammatory response of COPD patients and its relationship with serum inflammatory cytokine (IC) levels.
Methods: Eighty subjects were enrolled, including 40 COPD patients (COPD group) and 40 healthy controls (control group).

Conjugated porous polymers bearing flavone moieties (FL-CPPs) were synthesized a tandem approach. The carbonylative Sonogashira coupling in tandem with cyclization guided the assembling of building blocks with the accompanied production of flavone skeletons. The FL-CPPs were proved to be efficient metal-free photocatalysts for the [3+2] cycloaddition of phenols with olefins under the irradiation of visible-light.
View Article and Find Full Text PDFLaser absorption spectroscopy (LAS) is a well-established measurement technique for quantitative chemical speciation in a combustion environment. However, LAS measurement of nitric oxide (NO) in ammonia flames has never been reported in the literature. This is despite the community's recent strong interest in carbon-neutral ammonia combustion and the associated NO formation problem.
View Article and Find Full Text PDFMetasurfaces consisting of subwavelength structures have shown unparalleled capability in light field manipulation. However, their functionalities are typically static after fabrication, limiting their practical applications. Though persistent efforts have led to dynamic wavefront control with various materials and mechanisms, most of them work in free space and require specialized materials or bulky configurations for external control.
