Coagulopathy in Malnourished Mice Is Sexually Dimorphic and Regulated by Nutrient-Sensing Nuclear Receptors.

Liver dysfunction, including coagulopathy, is a prominent feature of protein-energy malnutrition. To identify mechanisms underlying malnutrition-associated coagulopathy, we administered a low-protein low-fat diet to lactating dams and examined hepatic transcription and plasma coagulation parameters in young adult weanlings. Malnutrition impacted body composition to a greater extent in male versus female mice.

Improved Biomarker and Imaging Analysis for Characterizing Progressive Cardiac Fibrosis in a Mouse Model of Chronic Chagasic Cardiomyopathy.

Background Chronic chagasic cardiomyopathy (CCC), caused by infection, is an important public health problem attributable to progressive cardiomyopathy in patients, for which there is no cure. Chronic chagasic cardiomyopathy is characterized by myocarditis and cardiac fibrosis, which leads to life-threatening arrhythmogenic and circulatory abnormalities. This study aimed to investigate cardiac fibrosis progression in a mouse model of chronic chagasic cardiomyopathy.
