Alternative Treatment for Residual Aortobronchial Fistula After Thoracic Endovascular Aortic Repair.

A patient with an aortobronchial fistula secondary to a thoracic endovascular aortic repair was successfully treated with a re-thoracic endovascular aortic repair with debranching technique. Five months postoperatively, the aneurysm had shrunk; however, computed tomography revealed air in the thrombo-excluded aortic aneurysmal sac without signs of infection. Because of worsening air finding at the eighth month, we performed a resection of the residual fistula and wrapped the stent graft in a pedicled muscle flap.

HubP, a Polar Landmark Protein, Regulates Flagellar Number by Assisting in the Proper Polar Localization of FlhG in Vibrio alginolyticus.

The marine bacterium Vibrio alginolyticus has a single polar flagellum, the number of which is regulated positively by FlhF and negatively by FlhG. FlhF is intrinsically localized at the cell pole, whereas FlhG is localized there through putative interactions with the polar landmark protein HubP. Here we focused on the role of HubP in the regulation of flagellar number in V.

Large-area spectrally encoded confocal endomicroscopy of the human esophagus in vivo.

Background And Objective: Diagnosis of esophageal diseases is often hampered by sampling errors that are inherent in endoscopic biopsy, the standard of care. Spectrally encoded confocal microscopy (SECM) is a high-speed reflectance confocal endomicroscopy technology that has the potential to visualize cellular features from large regions of the esophagus, greatly decreasing the likelihood of sampling error. In this paper, we report results from a pilot clinical study imaging the human esophagus in vivo with a prototype SECM endoscopic probe.

A case report of primary cardiac myxofibrosarcoma presenting with severe congestive heart failure.

Background: Primary cardiac sarcomas are extremely rare. Furthermore, the myxofibrosarcomas are one of the rarest forms of cardiac sarcomas, and its prognosis is known to be quite poor.

Case Presentation: This is a case of a 23-year-old man who presented with acute severe congestive heart failure caused by almost complete obstruction of the mitral valve due to a large left atrial tumor.

Automated segmentation and characterization of esophageal wall in vivo by tethered capsule optical coherence tomography endomicroscopy.

Optical coherence tomography (OCT) is an optical diagnostic modality that can acquire cross-sectional images of the microscopic structure of the esophagus, including Barrett's esophagus (BE) and associated dysplasia. We developed a swallowable tethered capsule OCT endomicroscopy (TCE) device that acquires high-resolution images of entire gastrointestinal (GI) tract luminal organs. This device has a potential to become a screening method that identifies patients with an abnormal esophagus that should be further referred for upper endoscopy.

Bladder and rectal incontinence without paraplegia or paraparesis after endovascular aneurysm repair.

Spinal cord ischemia is a well-known potential complication of endovascular aneurysm repair (EVAR), and it is usually manifested by paraplegia or paraparesis. We describe a case in which spinal cord ischemia after EVAR presented by isolated bladder and rectal incontinence without other neurological deficits. A 63-year-old woman presented with intermittent claudication secondary to an infrarenal abdominal aortic aneurysm (AAA), and a left common iliac artery obstruction, for which she underwent EVAR using an aorto-uniiliac (AUI) device and ilio-femoral artery bypass.

FliH and FliI ensure efficient energy coupling of flagellar type III protein export in Salmonella.

For construction of the bacterial flagellum, flagellar proteins are exported via its specific export apparatus from the cytoplasm to the distal end of the growing flagellar structure. The flagellar export apparatus consists of a transmembrane (TM) export gate complex and a cytoplasmic ATPase complex consisting of FliH, FliI, and FliJ. FlhA is a TM export gate protein and plays important roles in energy coupling of protein translocation.

[A Case of Delayed Vascular Injury as a Complication Related to Implanted Central Venous Port Catheter].

A 74-year-old woman with advanced gastric cancer was admitted to our hospital. A central venous (CV) port catheter was implanted into the right subclavian vein for preoperative chemotherapy and parenteral nutritional management. On the 35th day after implantation, she complained of diarrhea, fever and dyspnea.

Comprehensive confocal endomicroscopy of the esophagus in vivo.

Background And Study Aims: Biopsy sampling error can be a problem for the diagnosis of certain gastrointestinal tract diseases. Spectrally-encoded confocal microscopy (SECM) is a high-speed reflectance confocal microscopy technology that has the potential to overcome sampling error by imaging large regions of gastrointestinal tract tissues. The aim of this study was to test a recently developed SECM endoscopic probe for comprehensively imaging large segments of the esophagus at the microscopic level in vivo.

Thoracic Endovascular Aortic Repair for Challenging Aortic Arch Diseases Using Fenestrated Stent Grafts From Zone 0.

Background: Although previous reports have described the repair of distal aortic arch aneurysms through debranching and chimney techniques, these methods invariably involve surgical management of the carotid artery. We report clinical results of thoracic endovascular aortic repair (TEVAR) using fenestrated stent grafts in the treatment of aortic arch aneurysms located less than 15 mm from the left common carotid artery.

Methods: A semi-custom-made fenestrated stent graft designed to fit aortic arch tortuosity and preserve blood flow at least into the brachiocephalic and left common carotid arteries was placed from zone 0.

Preparation and electric property of polysilsesquioxane thin films incorporating carbazole groups.

New silsesquioxane incorporating a carbazole groups (PCTSQ) has been synthesized by a click thiol-ene reaction and a subsequent sol-gel reaction. To evaluate the electric property of this hybrid, diode devices have been fabricated by using PCTSQ thin film by spin-coating onto n-type ZnO film prepared by the electrodeposition method. The thin film hybrid devices showed good electric characteristics and high rectification ratio, as well as worked as a rectifier.

Hemobilia associated with a giant thrombosed aneurysm of the hepatic artery requiring hepatectomy.

Hemobilia is an unusual and potentially catastrophic cause of gastrointestinal bleeding. Although hepatic artery aneurysm is a cause of hemobilia, nontraumatic cases are infrequently reported. Herein, we describe the case of a giant hepatic artery aneurysm requiring hepatectomy because of repeated hemobilia in a patient with Marfan syndrome.

Rapid expansion of mycotic aneurysm of left coronary sinus of Valsalva causing myocardial ischemia: report of a case.

We described a 71-year-old female of aneurysm of the left sinus of Valsalva from mycotic origin. She underwent aortic valve replacement 11 years ago. Repeated CT scans showed rapidly growing aneurysm below the left coronary ostium.

Tethered confocal endomicroscopy capsule for diagnosis and monitoring of eosinophilic esophagitis.

Eosinophilic esophagitis (EoE) is an allergic condition that is characterized by eosinophils infiltrating the esophageal wall. The treatment of the disease may require multiple follow up sedated endoscopies and biopsies to confirm elimination of eosinophils. These procedures are expensive, time consuming, and may be difficult for patients to tolerate.

Construction of functional fragments of the cytoplasmic loop with the C-terminal region of PomA, a stator component of the Vibrio Na+ driven flagellar motor.

The membrane motor proteins, PomA (polar flagellar motility protein A) and PomB (polar flagellar motility protein B), of Vibrio alginolyticus form a stator complex that converts energy from the ion flow to mechanical work in bacterial flagellar motors. The cytoplasmic domain of PomA is believed to interact with the rotor protein FliG to make a torque. In this study, to investigate the function of the cytoplasmic domain of PomA, we constructed a series of fragments that flank the cytoplasmic loop of PomA between the second and third transmembrane (TM) domains (A-loop) and the C-terminal region, and expressed them in Escherichia coli together with PomA and PotB (a chimeric protein of PomB and MotB).

Incidence and predictors of adenocarcinoma following endoscopic ablation of Barrett's esophagus.

Background: The rate and risk factors of recurrent or metachronous adenocarcinoma following endoscopic ablation therapy in patients with Barrett's esophagus (BE) have not been specifically reported.

Aim: The aim of this study was to determine the incidence and predictors of adenocarcinoma after ablation therapy for BE high-grade dysplasia (HGD) or intramucosal carcinoma (IMC).

Methods: This is a single center, retrospective review of prospectively collected data on consecutive cases of endoscopic ablation for BE.

Pharmacological evidence showing significant roles for potassium channels and CYP epoxygenase metabolites in the relaxant effects of docosahexaenoic acid on the rat aorta contracted with U46619.

Docosahexaenoic acid (DHA) shows more pronounced relaxation when blood vessel is contracted with prostanoid receptor agonists than other stimulants. The present study was carried out to obtain information on the mechanisms underlying prostanoid receptor-selective relaxant action of DHA, particularly focusing on the possible roles for K(+) channels and its CYP epoxygenase (EOX) metabolites. In endothelium-denuded rat thoracic aorta, DHA (10(-5) M) almost completely relaxed U46619 (a thromboxane A2 (TP) receptor agonist)-contracted muscle without substantially affecting noradrenaline (NA)-induced contraction.
