We describe a patient with gastroparesis after radiofrequency catheter ablation (RFCA) as a result of vagus nerve injury. A 42-year-old man underwent redo-RFCA due to recurrent drug-resistant symptomatic atrial fibrillation. The patient complained of indigestion and early satiety 2 weeks after the second procedure. There was also weight loss of(More)
In recent years microRNAs (miRNAs) have been established as important biomarkers in a variety of diseases including cancer, diabetes, cardiovascular disease, aging, Alzheimer's disease, asthma, autoimmune disease and liver diseases. As a consequence, a variety of monitoring methods for miRNAs have been developed, including a fast and simple method for miRNA(More)
MicroRNAs (miRNAs) are small regulatory RNAs (size ∼21nt to ∼25nt) that can be used as biomarkers of disease diagnosis, and efforts have been directed towards the invention of a rapid, simple and sequence-selective detection method for miRNAs. We recently developed a DNA/silver nanoclusters (AgNCs)-based turn-off fluorescence method in the presence of(More)
MicroRNAs (miRNAs), small non-coding RNA molecules, are important biomarkers for research and medical purposes. Here, we describe the development of a fast and simple method using highly fluorescent oligonucleotide-silver nanocluster probes (DNA/AgNCs) to efficiently detect specific miRNAs. Due to the great sequence diversity of miRNAs in humans and other(More)
MicroRNAs (miRNAs) are small regulatory RNAs (size ~21 nt to ~25 nt) which regulate a variety of important cellular events in plants, animals and single cell eukaryotes. Especially because of their use in diagnostics of human diseases, efforts have been directed towards the invention of a rapid, simple and sequence selective detection method for miRNAs.(More)
Intracardiac lead fracture or free-wall perforation is a rare complication of implantable defibrillators. Complete disconnection of the fractured electrode has not been reported yet. Here, we report a case of lead fracture/disconnection and free-wall perforation, which occurred consecutively in a patient.
A highly coordinated complex known as the microprocessor precisely processes primary transcripts of MIRNA genes into mature miRNAs. In plants, the microprocessor minimally consists of three components: Dicer-like protein 1 (DCL1), HYPONASTIC LEAF 1 (HYL1), and SERRATE (SE). To precisely modulate miRNA maturation, the microprocessor cooperates with at least(More)
