Clinical predictors and noninvasive imaging in Fontan-associated liver disease: A systematic review and meta-analysis.

Background: Despite the development of several imaging modalities for diagnosing Fontan-associated liver disease (FALD), there is no optimal protocol for the follow-up of FALD. We conducted a systematic review and meta-analysis to identify factors related to liver fibrosis using biopsy reports and to identify alternative noninvasive modalities that could better reflect liver histological changes in FALD.

Methods: A systematic review and meta-analysis were conducted following the PRISMA guidelines Table S2.

Comparative Study on Hepatoprotective Effects of Traditional Herbs, Roots of Nakai, Fischer, Mill., and Fruits of Pall., on Ethanol-Induced Liver Injury in Mice.

Alcohol-associated liver disease (ALD) is a major cause of chronic liver disease, with few effective treatments besides alcohol abstinence. Angelicae Gigantis Radix (AG), Glycyrrhizae Radix et Rhizoma (GR), Paeoniae Radix (PR), and Zizyphi Fructus (ZF) are traditional herbs used to treat various ailments, including liver diseases. While several studies have reported the beneficial effects of GR on ALD, the effects of AG, PR, and ZF remain underexplored.

Acute perimyocarditis mimicking acute myocardial infarction in a 12-year-old boy with duchenne muscular dystrophy.

Differential diagnosis of chest pain in the pediatric population is important but can be challenging. A 12-year-old boy with Duchenne muscular dystrophy presented with chest pain, cardiac enzyme elevation, and convex ST elevations in the inferior leads with reciprocal ST depression in the anterior leads on electrocardiogram. Echocardiography on admission revealed normal left ventricular function.

Ciprofloxacin-Releasing ROS-Sensitive Nanoparticles Composed of Poly(Ethylene Glycol)/Poly(D,L-lactide-co-glycolide) for Antibacterial Treatment.

Since urinary tract infections (UTIs) are closely associated with oxidative stress, we developed ROS-sensitive nanoparticles for ciprofloxacin (CIP) delivery for inhibition of UTI. Poly(D,L-lactide-co-glycolide) (PLGA)- selenocystamine (PLGA-selenocystamine) conjugates were attached to methoxypoly(ethylene glycol) (PEG) tetraacid (TA) (TA-PEG) conjugates to produce a copolymer (abbreviated as LGseseTAPEG). Selenocystamine linkages were introduced between PLGA and TA to endow reactive oxygen species (ROS) sensitivity to nanoparticles.

A case of life-threatening valvulitis mimicking infective endocarditis in systemic juvenile idiopathic arthritis.

Differential diagnosis of an intracardiac mass is difficult when detected only by echocardiography before a biopsy is completed. However, treatment cannot be postponed until the biopsy results are obtained. We report the case of a 12-year-old girl who presented with an intracardiac mass in the mitral valve mimicking infective endocarditis and severe mitral regurgitation.

Rapid differentiation of astrocytes from human embryonic stem cells.

Astrocytes are abundant cells in the brain and have vital roles in various brain functions that include biochemical support of endothelial cells, supplying nutrients to the nervous tissue, maintaining the extracellular ion balance, etc. In developing nervous tissue, the differentiation of astrocytes occurs later compared to neurons. It takes more time and more techniques to obtain mature and pure astrocytes in vitro.
