We describe a method for the purification of normal human liver ferritin by ultrafiltration, gel filtration on Sephacryl S-300, and affinity chromatography on DEAE-Affi Gel Blue. The purity of the ferritin obtained was verified by immunoelectrophoresis, Ouchterlony immuno-diffusion, polyacrylamide gel electrophoresis, and electrofocusing. This rapid method yields 32% of the original ferritin.

Oxidative stress and neuronal apoptosis could be an important factor leading to post-hemorrhagic consequences after germinal matrix hemorrhage (GMH). Previously study have indicated that relaxin 2 receptor activation initiates anti-oxidative stress and anti-apoptosis in ischemia-reperfusion injury. However, whether relaxin 2 activation can attenuate oxidative stress and neuronal apoptosis after GMH remains unknown.

Background: Cirrhosis has been pointed out as a clinical entity that leads to worse clinical prognosis in COVID-19 patients. However, this concept is controversial in the literature. We aimed to evaluate clinical outcomes by comparing patients with cirrhosis to those without cirrhosis in a Brazilian cohort.

Bile acids (BAs) play important roles in the context of lipid homeostasis and inflammation. Based on extensive preclinical mouse studies, BA signaling pathways have been implicated as therapeutic targets for cardiovascular diseases. However, differences in BA metabolism between mice and humans hamper translation of preclinical outcomes.
