We screened actinomycete strains for dinitrogen (N(2))-producing activity and discovered that Streptomyces antibioticus B-546 evolves N(2) and some nitrous oxide (N(2)O) from nitrate (NO(3)(-)). Most of the N(2) that evolved from the heavy isotope ([(15)N]NO(3)(-)) was (15)N(14)N, indicating that this nitrogen species consists of two atoms, one arising from(More)
BACKGROUND AND AIM OF THE STUDY The timing of the surgical intervention for active infective endocarditis (IE) is particularly difficult when there is a cerebrovascular complication. The study aim was to investigate the results of surgical treatment for active IE in patients with recent cerebrovascular events, and to evaluate the relationship between the(More)
Platypnea-orthodeoxia is a rare syndrome presenting with dyspnea and cyanosis induced by an upright position and relieved by recumbency. We report a patient with an excessively enlarged aortic root who had critical hypoxia due to a paradoxical shunt through the patent foramen ovale only when seated. The postural changes of the shunt, caused by changes in(More)
We describe a case of successful surgical treatment for spontaneous rupture of an iliac artery aneurysm into a ureter. An 80-year-old man was admitted with massive hematuria. Immediate enhanced abdominal computed tomography scan and cystoscopy were suspicious for a uretero-arterial fistula caused by aneurysmal rupture. Emergent surgical intervention was(More)
We report herein the case of an 80-year-old woman who underwent successful redo coronary artery bypass grafting (CABG) for a saphenous vein graft aneurysm found 10 years after her initial operation. On presentation, coronary angiography (CAG) revealed aneurysmal dilatation of the saphenous vein graft and severe stenosis of the left main trunk (LMT). A(More)
Malassezia globosa is a major pathogen of Malassezia folliculitis (MF) and the predominant species on human skin. The aim of this study was to clarify the differences between M. globosa and other cutaneous Malassezia species, M. restricta, M. dermatis, M. sympodialis and M. furfur. The optimum growth temperature, effects of compounds of sweat and free fatty(More)
Prolongation of the QT interval, sometimes leading to torsades de pointes, has been clinically reported during terfenadine treatment. However, information regarding the cardiovascular profile of terfenadine is still limited, particularly in in vivo animal models. In the current study, we examined the cardiovascular effects of terfenadine using(More)
A 69-year–old man was referred to our department for surgical treatment of bilateral giant coronary artery aneurysms. He had no apparent clinical factors associated with atherosclerosis, such as diabetes mellitus, hyperlipidemia, or hypertension. Physical examination revealed no abnormalities. His medical history included malignant lymphoma that had been(More)
Malassezia folliculitis [MF] is caused by the invasion of hair follicles by large numbers of Malassezia cells, but it remains unclear which Malassezia species are involved in the disease. To clarify this situation, Malassezia species isolated from lesions of MF patients were analyzed by both culture and non-culture methods. In addition, Malassezia species(More)
OBJECTIVE Sorin Bicarbon (SB) and Edwards Mira (EM) valves have an identical mechanical design but different sewing cuffs. The purpose of this retrospective study was to analyze the long-term clinical and echocardiographic outcomes after mitral valve replacement with these two valves in a combined population of patients. METHODS We retrospectively(More)
