This study aimed to investigate in vivo dynamic metabolic changes after transplantation of induced pluripotent stem cells (iPSCs) and iPSC-derived enriched cardiomyocytes (iPSC-CMs) in a rat model of ischemic injury. METHODS: Serial 18F-FDG PET, …

It is well known that cardiac dysfunction develops during sepsis in both humans and in rodents (rats, mice). These defects appear to be reversible, since after “recovery” from sepsis, cardiac dysfunction disappears and the heart returns to its function …

Background: Thymosin beta 4 is a promising agent in preclinical regenerative and cardioprotection research. After myocardial injury it improves cell survival, reduces inflammation and activates epicardial progenitor cells. The peptide is also involved in …

Most studies of the mechanisms leading to hereditary dilated cardiomyopathy (DCM) have been performed in reconstituted in vitro systems. Genetically engineered murine models offer the opportunity to dissect these mechanisms in vivo. We generated a …

Ultrasound is critical in many areas of medicine including obstetrics, oncology, and cardiology with emerging applications in regenerative medicine. However, one critical limitation of ultrasound is the low contrast of target tissue over background. Here, …

Noonan syndrome (NS) is a common autosomal dominant disorder that presents with short stature, craniofacial dysmorphism, and cardiac abnormalities. Activating mutations in the PTPN11 gene encoding for the Src homology 2 (SH2) domain-containing protein …

PURPOSE: To analyze the responses of different retinal ganglion cell (RGC) types to acute ocular hypertension (AOH) and intravitreal administration of brain-derived neurotrophic factor (BDNF). METHODS: In adult albino rats, the anterior chamber of the …

Cardiac fibrosis, as a pathological process, plays an important role in various cardiac diseases. microRNA-155 (miR-155) is one of the most important miRNAs, and previous studies have shown that it is a regulatory factor in various fibrotic diseases. …

Blood vessels are the only system to provide nutrients and oxygen to every part of the body. Many diseases can have significant effects on blood vessel formation, so that the vascular network can be a cue to assess malicious tumor and ischemic tissues. …

BACKGROUND\nNoninvasive diagnostic tools for right ventricular (RV) dysfunction measurements are increasingly being used, although their association with the pathologic mechanisms of dysfunction is poorly understood. Although investigations have focused …
