[Early to Long-term Results of Left Atrial Appendage Closure Using Clip Device in Patients with Atrial Fibrillation].

Oral anticoagulants for atrial fibrillation are the standard approach to prevent stroke in patients with atrial fibrillation. However, oral anticoagulant therapy carries the risk of cerebral infarction recurrence, not to mention hemorrhagic complications, even under appropriate drug therapy. Surgical treatments targeting the left atrial appendage include left atrial appendage closure( LAAO) and left atrial appendage resection (LAAR).

[Less Invasive Surgical Closure of the Left Atrial Appendage for Cardiogenic Cerebral Embolism in a Patient with Dilated Cardiomyopathy].

Less invasive surgical closure of the left atrial appendage is recommended to prevent cardiogenic thromboembolism in patients with chronic non-valvular atrial fibrillation( Af) and other high-risk cardiac diseases such as dilated cardiomyopathy (DCM). We report a case of a 57-year-old man with Af and DCM. Catheter ablation for Af was contraindicated in this patient with a history of cardiogenic thromboembolism, and anticoagulation therapy was initiated.

Polyphenol oxidase from wheat bran is a serpin.

Differential expression of three ABA-insensitive five binding protein (AFP)-like genes in wheat.

Abscisic acid (ABA) signaling includes positive and negative regulators in the signaling pathway. ABA-insensitive five (ABI5) binding protein (AtAFP), one of the negative regulators found in Arabidopsis, is involved in the proteolysis of a positive regulator, ABI5 (bZIP-type transcription factor). Three wheat orthologs (TaAFPs) of AtAFP were isolated.

Differential changes in cell wall matrix polysaccharides and glycoside-hydrolyzing enzymes in developing wheat seedlings differing in drought tolerance.

The growth kinetics and variations in cell wall matrix polysaccharides and glycoside hydrolases during seedling development of the drought-tolerant wheat cultivar (cv. Hong Mang Mai) were compared with the drought-sensitive cultivar (cv. Shirasagikomugi).

A novel alpha-glucosidase from the moss Scopelophila cataractae.

Scopelophila cataractae is a rare moss that grows on copper-containing soils. S. cataractae protonema was grown on basal MS medium containing copper.

Isolation of bisphenol A-tolerant/degrading Pseudomonas monteilii strain N-502.

Bisphenol A (BPA) is a highly biotoxic compound that kills many microorganisms at a low concentration (1,000 ppm). We isolated BPA-tolerant/degrading Pseudomonas monteilii strain N-502 from about 1,000 samples collected from a field, sewage, and pond water. The isolated strain had strong BPA tolerance and high BPA-degrading activity.

Evidence of dual function of macrophage migration inhibitory factor relevant to tumor progression and regression.

Macrophage migration inhibitory factor (MIF) is known to play an important role in broad-spectrum inflammation and immune responses. To evaluate the role of MIF in tumor growth, we established transgenic (Tg) mice (ICR strain) driven by cytomegalovirus (CMV) enhancer and beta-actin promoter. We inoculated Tg mice in the back with murine sarcoma cell line S-180 cells.

Purification and characterization of an alpha-glucosidase from germinating millet seeds.

MUC20 suppresses the hepatocyte growth factor-induced Grb2-Ras pathway by binding to a multifunctional docking site of met.

A cDNA encoding a novel mucin protein, MUC20, was isolated as a gene that is up-regulated in the renal tissues of patients with immunoglobulin A nephropathy. We demonstrate here that the C terminus of MUC20 associates with the multifunctional docking site of Met without ligand activation, preventing Grb2 recruitment to Met and thus attenuating hepatocyte growth factor (HGF)-induced transient extracellular signal-regulated kinase-1 and -2 activation. Production of MUC20 reduced HGF-induced matrix metalloproteinase expression and proliferation, which require the Grb2-Ras pathway, whereas cell scattering, branching morphogenesis, and survival via the Gab1/phosphatidylinositol 3-kinase (PI3K) pathways was not affected.

Transgene of MIF induces podocyte injury and progressive mesangial sclerosis in the mouse kidney.

Background: Recent evidence suggests that macrophage migration inhibitory factor (MIF) is a proinflammatory cytokine that plays a pathogenic role in glomerulonephritis. Renal expression of MIF is up-regulated in infiltrating and intrinsic renal cells, which include glomerular epithelial cells. The aim of the current study was to further clarify the role of MIF produced by podocytes in the process of renal disease.

Molecular cloning, genomic structure, and expression analysis of MUC20, a novel mucin protein, up-regulated in injured kidney.

Immunoglobulin A nephropathy (IgAN) is the most common primary glomerulonephritis in the world. Here, we identify a cDNA encoding a novel mucin protein, shown previously to be up-regulated in IgAN patients, from a human kidney cDNA library. This protein contains a mucin tandem repeat of 19 amino acids consisting of many threonine, serine, and proline residues and likely to be extensively O-glycosylated; thus, this gene was classified in the mucin family and named MUC20.
