Endovascular Aortic Repair for a Symptomatic Mycotic Aneurysm With : A Case Report.

Purpose: To report a case of successful endovascular aortic repair for a symptomatic mycotic abdominal aortic aneurysm infected with .

Case Report: We report the case of an 88-year-old woman who presented with acute abdominal pain and vomiting. Approximately a year prior to her presentation, the patient was diagnosed with a mycotic abdominal aortic aneurysm with and was treated conservatively for more than 2 months at another hospital.

Surgical Management of Perigraft Seroma by Graft Wrapping with Local Hemostatic Agents: A Case Report.

A 76-year-old female developed progressive local groin bulging. She received regular hemodialysis using a left-thigh polytetrafluoroethylene arteriovenous graft in the loop configuration. Lower extremity enhanced computed tomography showed a large low-density area around the graft 18 months after its creation, and perigraft seroma (PS) was suspected.

Aortic Root Replacement via Lower Hemisternotomy After an Esophageal Operation.

A 68-year-old man with a history of esophageal resection and reconstruction by gastric tube in substernal fashion required aortic root replacement for annuloaortic ectasia and severe aortic regurgitation. The gastric tube attached closely at the manubrium of the sternum and around the xiphoid process, but it positioned leftward slightly at the body of the sternum. At the operation of the aortic root replacement, we decided the lower hemisternotomy approach to avoid injury of the gastric tube.

Peripheral Arterial Disease with Small Aorta Syndrome: A Case Report.

We report a case of a 79-year-old woman who experienced difficulty in walking. Contrast-enhanced computed tomography revealed severe stenosis and calcification of the infrarenal aorta. The minimum diameter of the infrarenal aorta was 8 mm and that of the common femoral artery was 4 mm.

Pseudomonas atagosis sp. nov., and Pseudomonas akappagea sp. nov., New Soil Bacteria Isolated from Samples on the Volcanic Island Izu Oshima, Tokyo.

During the exploration of microbial natural resources, two strains of Pseudomonas, PS14 and PS24, were isolated from samples taken from Izu Oshima, a volcanic island located 120 km southwest of central Tokyo. Phylogenetic analysis based on 16S rRNA gene sequences showed that PS14 was most similar to Pseudomonas baetica a390 (99.6%) and Pseudomonas helmanticensis OHA11 (99.

[Re-operation for Saccular Aneurysm after Ascending Aortic Replacement with Homograft;Report of a Case].

A 62-years-old female had undergone ascending aortic replacement with homograft for graft infection and mediastinitis after initial replacement of ascending aorta due to acute type A dissection. Ten years after homograft replacement, follow up computed tomography showed acute growing saccular aneurysm of the homograft without infectious symptoms. We urgently performed Bentall procedure and hemiarch replacement successfully.

Absent right common carotid artery associated with aberrant right subclavian artery.

Rarely, the external and internal carotid arteries arise separately from the brachiocephalic trunk and right subclavian artery (SA) or the aortic arch and reflect the absence of a common carotid artery (CCA). We report a 45-year-old man with absent right CCA associated with aberrant right SA, an extremely rare combination, diagnosed by computed tomography (CT) angiography during follow-up for postoperative aortic dissection. Retrospective careful observation of preoperative postcontrast CT revealed the absent right CCA.

AM251 Suppresses Epithelial-Mesenchymal Transition of Renal Tubular Epithelial Cells.

Epithelial-mesenchymal transition (EMT) of renal tubular epithelial cells is one of the causative mechanisms of kidney fibrosis. In our study, we screened lipophilic compounds using a lipid library including approximately 200 lipids to identify those that suppressed EMT induced by a transforming growth factor (TGF)-β1 stimulus. Initial screening was performed with the immortalized HK-2 renal tubule epithelial cell line.

Preserved autoregulation of coronary flow after off-pump coronary artery bypass grafting: retrospective assessment of intraoperative transit time flowmetry with and without intra-aortic balloon counterpulsation.

Background: Intra-aortic balloon pumping (IABP) markedly increases graft flow after coronary artery bypass grafting (CABG) with cardiopulmonary bypass. We sought to delineate the effects of IABP on graft flow after off-pump CABG (OPCAB).

Methods: The clinical records of 32 patients (25 male, 7 female; mean age: 70 ± 9 years) who underwent OPCAB with IABP between January 2011 and May 2015 were retrospectively reviewed.

[Surgery for Ventricular Tachycardia Arising from Left Ventricular Aneurysm in a Patient with Dilated Cardiomyopathy；Report of a Case].

A left ventricular aneurysm (LVA) generally results from myocardial infarction, but rarely LVA can be associated with dilated cardiomyopathy (DCM). We herein report a surgical case of malignant ventricular tachycardia (VT) in a patient with LVA associated with DCM. A 57-year-old woman was diagnosed with DCM and LVA when she 1st presented with sustained VT.

A selective peroxisome proliferator-activated receptor δ agonist PYPEP suppresses atherosclerosis in association with improvement of the serum lipoprotein profiles in human apolipoprotein B100 and cholesteryl ester transfer protein double transgenic mice.

Objective: Although peroxisome proliferator-activated receptor (PPAR) δ agonists have been shown to improve the serum lipoprotein profiles in humans, the impact of the changes in these lipoprotein profiles on atherosclerosis remains to be elucidated. The aim of this study was to investigate the relationship between the selective PPARδ agonist-induced alterations of serum lipoprotein profiles and the development of atherosclerosis in human apolipoprotein B100 and cholesterol ester transfer protein double transgenic (hApoB100/hCETP-dTg) mice with human-like hypercholesterolemic dyslipidemia.

Methods: hApoB100/hCETP-dTg mice fed an atherogenic diet received a novel PPARδ agonist (PYPEP) or vehicle for 18 weeks, followed by evaluation of atherosclerosis.

Comparison of early haemodynamics of 19-mm aortic valve bioprostheses in patients with a small aortic annulus.

Objectives: A potential problem in aortic valve replacement (AVR) for patients with a small aortic annulus is prosthesis-patient mismatch (PPM). Although larger size prostheses have been well studied, the haemodynamics of 19-mm bioprostheses has been reported in only a small number of patients. The Trifecta valve is a novel bioprosthesis and its unique design is conceived to increase effective orifice area (EOA) and prevent PPM.

Diagnostic features of cardiac cavernous hemangioma in the right ventricle on magnetic resonance imaging.

Cardiac tumors are rare; however, with recent advances in imaging techniques, they are being diagnosed more frequently with cardiac magnetic resonance (CMR) imaging. We report a case of a cardiac cavernous hemangioma in the right ventricle. This case was diagnosed with CMR imaging based on the characteristic features of peripheral nodular contrast enhancement and progressive centripetal fill-in.

Impacts of intraoperative flow on graft patency of sequential and individual saphenous vein grafts.

Objective: We sought to delineate the predictor of saphenous vein graft (SVG) failure and to evaluate the impact of sequential grafting of SVG on graft flow as the significant predictor of patency.

Methods: Angiograms and clinical records of 439 patients who underwent coronary artery bypass grafting with aortocoronary SVG were reviewed. Of these, 708 distal anastomoses were created by 480 SVGs.

Myectomy as an alternative solution for systolic anterior motion in a patient who underwent mitral valve repair.

Systolic anterior motion (SAM) of the mitral apparatus is a relatively frequent complication of mitral valve repair. When significant SAM persists despite intraoperative medical therapies, a second repair is generally required. We describe a rare case of SAM due to a hypertrophic septum in a patient who underwent mitral valve repair, with no preoperative obstruction of the left ventricular outflow tract.

Comparative molecular and microbiological diagnosis of 19 infective endocarditis cases in which causative microbes were identified by PCR-based DNA sequencing from the excised heart valves.

Infective endocarditis (IE) is traditionally diagnosed by microbiological analysis of blood cultures, following which therapeutic antibiotics are chosen based on antimicrobial sensitivity tests. However, such conventional techniques do not always lead to an accurate etiological diagnosis. Recently, PCR analysis of the 16S rRNA gene has been employed to identify organisms isolated from excised heart valves.

Evaluation of perivalvular infectious ventricular pseudoaneurysm by ECG-gated cardiac computed tomography: 2 case reports.

Left ventricular (LV) pseudoaneurysm is a serious complication of periannular extension of infective endocarditis (IE). Because pseudoaneurysm carries a high risk of rupture, its detection and evaluation are crucial for patient management and surgical planning. We report 2 cases with LV pseudoaneurysms, one near the aortic valve and the other near the mitral valve, which were caused by IE and treated successfully.

[New surgical approach for acute type A aortic dissection; combining classic surgery with descending stent grafting].

The outcome of surgical repair of acute type A dissection has substantially improved, but patients with residual dissection in the descending aorta are facing a risk of late complications such as aneurysm formation and rupture, and often require redo surgery. To minimize late complications, the combined approach with hemi-arch replacement and simultaneous descending stent grafting (SG) was applied and compared with conventional surgery. Between April 2007 and April 2010, 70 consecutive patients with acute type A dissection underwent operation, and 8 with DeBakey type II and 9 undergoing total-arch replacement were excluded from the study.

A double epitope tag for quantification of recombinant protein using fluorescence resonance energy transfer.

The expression of recombinant proteins is a well-accepted technology, but their detection and purification often require time-consuming and complicated processes. This paper describes the development of a novel double epitope tag (GEPGDDGPSGAEGPPGPQG) for rapid and accurate quantification of recombinant protein by a homogeneous immunoassay based on fluorescence resonance energy transfer. In our double epitope tagging system, recombinant proteins can be simply measured on a microtiter plate by addition of a pair of fluorophore-labeled monoclonal antibodies (their epitopes; GEPGDDGPS and GPPGPQG).

Ascending to descending aorta bypass for middle aortic syndrome.

Though stenoses of the descending aorta and its branches are seen with congenital anomalies or systemic inflammation, occlusion of the descending aorta is extremely rare. A patient with an occluded hypoplastic descending thoracic aorta required re-operation because of graft failure between the descending thoracic aorta and the infrarenal abdominal aorta. The etiology of the aortic occlusion in this case is unknown, but inflammation, such as Takayasu disease, is speculated.

HU0622: a small molecule promoting GAP-43 activation and neurotrophic effects.

During the course of neuronal development or regeneration, the axonal growth cone protein growth-associated protein 43 (GAP-43) is expressed in a great majority of differentiating neurons, suggesting that the regulation of this gene is tied to important differentiation signals common to many neurons. In order to discover non-peptide molecules capable of mimicking the effects of NGF, we developed a reporter gene assay system based on measurement of light production in PC12 cells stably transfected with the luciferase reporter gene, the expression of which depends on the transcriptional activation of GAP-43. High throughput screening of the proprietary compound collection using this system revealed (E,E)-1-[5-(3,4-dihydroxyphenyl)-1-oxo-2,4-pentadienyl]piperidine (HU0622), a piperine derivative, to be an activator of GAP-43 transcription.
