Measuring serum ferritin under field conditions

Diagnosis of coronavirus by measuring serum concentrations of IL-6 and blood ferritin

Aims:The purpose of this study is to explore changes of pathogenesis markers in peripheral blood of severe COVID-19 patients, which may be of value in disease monitoring. Methods: In this case-control study, we collected data of 180 subjects in two groups including 137 patients with COVID-19 (case) and 43 with non-COVID-19 (control) between March 20 and May 21, 2020, and the clinical characte...

Serum ferritin.

(1) Brief introduction to iron metabolism and the biochemistry of ferritin. (2) Early studies of circulating ferritin. (3) Methods for measuring serum ferritin concentrations -- immunoradiometric, radioimmuno- and enzyme-linked immuno assays based on liver or spleen ferritin -- an evaluation of these techniques. (4) Serum ferritin concentrations in normal subjects -- definition of normality -- ...

Radioimmunoassay of serum ferritin.

Purified human spleen ferritin was labelled with 125I. On Sepharose 6-B gel filtration four species of labelled products were separated: a component with a higher molecular weight than ferritin; a component which is eluted in the same volume as unlabelled ferritin; and two labelled compounds with molecular weights lower than ferritin. When these labelled materials were used in a double antibody...

Photosynthesis in the Potato Under Field Conditions.

In spite of the importance of the potato as a food, little is known about the effect of environmental factors on photosynthesis in the plant. Studies with several other crops (1, 12, 16, 23, 24) have not only added to the knowledge of photosynthesis but have aided in understanding certain responses of these crops to environmental variations. VERDUIN and LooMIs (24) and GABRIELSON (10) have show...
