Eco-Friendly Analytical Approach for Sensitive Spectrofluorimetric Determination of the Flavonoid Chrysin in Capsules and Human Plasma.

Chrysin is a plant flavonoid that has different therapeutic effects as anti-inflammatory, anti-cancer, anti-oxidant, and immune booster. Spectrofluorimetry has received a lot of interest lately because of its ecological greenness and analytical performance. This approach employed the native fluorescence of chrysin at 339 nm following excitation at 231 nm in distilled water.

Serum Cystatin C as a Biomarker in Diffuse Large B-Cell Lymphoma.

Elevated serum levels of cystatin C are found to be related to poor outcome and metastatic potential of some malignant disorders. To evaluate the clinical prominence of serum cystatin C in diffuse large B-cell lymphoma (DLBCL), blood samples were obtained from 58 patients at the time of diagnosis and paired blood samples were obtained from 22 patients at the time of remission. Also, serum cystatin C level was measured in matched healthy controls.
