The management of liver disease in people with congenital bleeding disorders: guidance from European Association for Haemophilia and Allied Disorders, European Haemophilia Consortium, ISTH, and World Federation of Hemophilia.

People with bleeding disorders (PWBD) have been exposed to the risk of developing chronic viral hepatitis and cirrhosis after replacement therapy. Today, the advent of new pharmacologic strategies for the control of hemostasis and the efficacious antiviral therapies against hepatitis C virus and hepatitis B virus have significantly reduced this risk. However, the definitive success for liver health in this clinical setting is also influenced by other factors, such as the severity of liver disease at the time of hepatitis B virus/hepatitis C virus antiviral therapy and the exposure to highly prevalent factors of chronic liver damage (eg, metabolic dysfunction and/or alcohol) that can cause a residual risk of complications such as hepatocellular carcinoma, portal hypertension, and liver insufficiency.

Suppression of ZEB1 by Ethyl caffeate attenuates renal fibrosis via switching glycolytic reprogramming.

Renal fibrosis (RF) is a common endpoint of various chronic kidney diseases, leading to functional impairment and ultimately progressing to end-stage renal failure. Glycolytic reprogramming plays a critical role in the pathogenesis of fibrosis, which maybe a potential therapeutic target for treating renal fibrosis. Here, we revealed the novel role of ZEB1 in renal fibrosis, and whether targeting ZEB1 is the underlying mechanism for the anti-fibrotic effects of ethyl caffeate (EC) to regulate the glycolytic process.

Half-Life and Clearance of Cardiac Troponin I and Troponin T in Humans.

Background: Cardiac troponin (cTn) is key in diagnosing myocardial infarction (MI). After MI, the clinically observed half-life of cTn has been reported to be 7 to 20 hours, but this estimate reflects the combined elimination and simultaneous release of cTn from cardiomyocytes. More precise timing of myocardial injuries necessitates separation of these 2 components.

Atlas of Regional Left Ventricular Scar in Nonischemic Cardiomyopathies: Substrates and Etiologies.

Most acquired and inherited cardiomyopathies are characterized by regional left ventricular involvement and nonischemic myocardial scars, often with a disease-specific pattern. Irrespective of the etiology and pathophysiological mechanisms, myocardial disorders are invariably associated with cardiac fibrosis, which contributes to dysfunction and electrical instability. Accordingly, cardiac magnetic resonance plays a central role in the diagnostic work-up and prognostic risk stratification of cardiomyopathies, particularly with the increasing correlation between genetic background and specific disease phenotype.

RAD52 resolves transcription-replication conflicts to mitigate R-loop induced genome instability.

Collisions of the transcription and replication machineries on the same DNA strand can pose a significant threat to genomic stability. These collisions occur in part due to the formation of RNA-DNA hybrids termed R-loops, in which a newly transcribed RNA molecule hybridizes with the DNA template strand. This study investigated the role of RAD52, a known DNA repair factor, in preventing collisions by directing R-loop formation and resolution.
