Hydrogenosomes are membrane-bounded organelles about 1 mm in size that, like mitochondria, produce ATP (Müller 1993). They compartmentalize terminal steps of anaerobic energy metabolism but, unlike mitochondria, hydrogenosomes cannot use oxygen as an electron acceptor; they reduce protons to molecular hydrogen (Embley and Martin 1998; Martin and Müller 1998; Müller 1998). Hydrogenosomes have be...

Excellent definition of anatomic structure, ability to provide detailed flow information, and a global field of view make magnetic resonance imaging (MRI) well suited as a tool for the noninvasive diagnosis of congenital heart disease. One of the most frequently encountered lesions is the atrial septa1 defect (ASD), which may be associated with important morbidity in the long term if unrecogniz...

2214-0271 B 2015 Heart Rhythm Society. Published by Elsevier Inc. This is an o (http://creativecommons.org/licenses/by-nc-nd/4.0/). Introduction A transseptal puncture through the interatrial septum at or near the fossa ovalis is frequently used to access the left side of the heart for electrophysiologic procedures. Fluoroscopy and intracardiac ultrasonography are imaging modalities commonly em...

Two new Stenus species of the cirrus group collected from Zhejiang Province, East China, are described, S. wuyanlingus Liu, Tang & Luo, sp. n., S. yuyimingi Liu, Tang & Luo, sp. n. and a new distributional locality for S. ovalis Tang, Li & Zhao, 2005 was discovered. The diagnostic characters of the new species are illustrated, and a key to species of the group from Zhejiang Province is provided.

This report describes a family with frequent recurrence of congenital heart disease in multiple generations. Eight members had atrial septal defect (ASD) of the fossa ovalis type and seven members had other forms of congenital heart disease. One branch of the pedigree showed a predominance of ASD with prolonged atrioventricular (A-V) conduction and initially suggested an autosomal dominant gene...

Large single crystals of iron-containing superoxide dismutase from Pseudomonas ovalis were prepared from 50% saturated ammonium sulfate solution, at pH 4.5, on gentle evaporation of the solvent at 4 degrees. The crystals were monoclinic, space group P2, with unit cell dimensions a = 81.9 A, b = 49.0 A, c = 61.0 A, and beta = 106 degrees. Considerations of cell volume and protein molecular weig...

Percutaneous pulmonary balloon valvuloplasty as a procedure of choice in adults has been established since the last three decades. Even though the complications are rare, they are scarcely reported in the literature. We report such a case in an adult female patient of severe pulmonary valular stenosis in whom, entrapped catheter across the fossa ovalis was noted in chest x-ray and echocardiogra...

Situs inversus with mirror-image of the heart is a rare condition. The present report describes a case of a patient with dextrocardia with situs inversus who had atrial septal defect with multiple holes in the fossa ovalis. The patient underwent total endoscopic atrial septal defect repair using the da Vinci surgical system. This procedure was achieved safely with good clinical and excellent co...
