Establishment of a Model of Renal Impairment with Mild Renal Insufficiency Associated with Atrial Fibrillation in Canines

Background Chronic kidney disease and occurrence of atrial fibrillation (AF) are closely related. No studies have examined whether renal impairment (RI) without severe renal dysfunction is associated with the occurrence of AF. Methods Unilateral RI with mild renal insufficiency was induced in beagles by embolization of small branches of the renal artery in the left kidney for 2...

Renal Denervation Suppresses Atrial Fibrillation in a Model of Renal Impairment

Background A close association exists between renal impairment (RI) and atrial fibrillation (AF) occurrence. Increased activity of the sympathetic nervous system (SNS) may contribute to the development of AF associated with RI. Renal denervation (RDN) decreases central sympathetic activity. Objective The main objective of the study was to explore the effects of RDN on AF...

Disruption of Secondary Wall Cellulose Biosynthesis Alters Cadmium Translocation and Tolerance in Rice Plants

Tricheary elements (TEs), wrapped by secondary cell wall, play essential roles in water, mineral, and nutrient transduction. Cadmium (Cd) is a toxic heavy metal that is absorbed by roots and transported to shoot, leaves, and grains through vascular systems in plants. As rice is a major source of Cd intake, many efforts have been made to establish ‘low-Cd rice’. However, no links...

Up-Regulation of Hepatoma-Derived Growth Factor Facilities Tumor Progression in Malignant Melanoma

Cutaneous malignant melanoma is the fastest increasing malignancy in humans. Hepatoma-derived growth factor (HDGF) is a novel growth factor identified from human hepatoma cell line. HDGF overexpression is correlated with poor prognosis in various types of cancer including melanoma. However, the underlying mechanism of HDGF overexpression in developing melanoma remains unclear. In...

Genetic characterization of the mRNAs encoding α-bungarotoxin: Isoforms and RNA editing in Bungarus multicinctus gland cells

The mRNA encoding α-bungarotoxin (α-Butx) was prepared from the venom glands of Bungarus multicinctus by Cap-finder cDNA synthesis. The sequences of the 3′- and 5′-flanking regions including a signal peptide of α-Butx were almost identical with those of Elapidae and Hydrophiidae toxins, suggesting that they may have the same origin. Sixteen polymorphic mRNA sequences of α-Butx...
