Thraustochytrium sp. 26185 accumulates a high level of docosahexaenoic acid (DHA), a nutritionally important ω-3 very long chain unsaturated fatty acid (VLCPUFA) synthesized primarily by polyunsaturated fatty acid (PUFA) synthase, a Type I polyketide synthase-like mega-enzyme. The PUFA synthase in this species comprises three large subunits each with multiple catalytic domains. It was hypothesized that among these domains, ketoacylsynthase (KS) domains might be critical for catalyzing the condensation of specific unsaturated acyl-ACPs with malonyl-ACP, whereby retaining double bonds in an extended acyl chain...

Complex lesions of the thoracic aorta are traditionally treated in 2 surgical steps with the elephant trunk technique. A relatively new approach is the frozen elephant trunk (FET) technique, which potentially allows combined lesions of the thoracic aorta to be treated in a 1-stage procedure combining endovascular treatment with conventional surgery using a hybrid prosthesis. These are very complex and time-consuming operations, and good results can be obtained only if appropriate strategies for myocardial, cerebral, and visceral protection are adopted...

We report the case of a 58-year-old man who presented with thoraco-abdominal pain and right lower limb ischemia due to type B aortic dissection. Moreover, the patient was discovered to have several concomitant aortic arch anomalies (bovine arch, arteria lusoria, and left vertebral artery arising from the aortic arch). Taking into account this complex anatomy, emergent femoral exploration with fenestration and thrombectomy was performed. The blood flow to the right lower limb was restored. A few days later the aortic dissection spread proximally, and the aortic arch dilatation enlarged...

A 63-year-old man was seen by his family doctor for epigastric distress, and he was referred to our hospital with a diagnosis of gastric cancer. Upper gastrointestinal endoscopy revealed type 3 gastric cancer(por1>tub2>tub1)at the lesser curvature of the stomach. Computed tomography suggested thickening of the wall of the stomach at the lesser curvature and bulky lymph node swelling. After a diagnosis of cT4a cN2M0, cStage III B advanced gastric cancer, we treated him with neoadjuvant chemotherapy consisting of 3 courses of SOX(oxaliplatin 100mg/m / 2 on day 1, S-1 120mg/day on day 1-14, followed by 7 days of rest)...

STUDY QUESTION: Does irradiation evoke adverse effects in germ and somatic cells in testis xenografts from prepubertal monkeys? SUMMARY ANSWER: In addition to the expected depletion of germ cells, a dose-dependent effect of irradiation was observed at the mRNA and protein level in Sertoli and peritubular myoid cells. WHAT IS KNOWN ALREADY: Testicular irradiation studies in monkeys have focused on the dose-dependent effects on germ cells. Previous studies using intact animals or xenografts reported that germ cells are highly sensitive to irradiation...

BACKGROUND AND PURPOSE: Pseudo-occlusion (PO) of the cervical internal carotid artery (ICA) refers to an isolated occlusion of the intracranial ICA that appears as an extracranial ICA occlusion on computed tomography angiography (CTA) or digital subtraction angiography because of blockage of distal contrast penetration by a stagnant column of unopacified blood. We aim to better characterize this poorly recognized entity. METHODS: Retrospective review of an endovascular database (2010-2015; n=898)...

The endothelium, which is at the interface between circulating blood and the vascular wall, comprises a simple squamous layer of cells that lines the inner surface of all blood vessels. Endothelial cells are highly metabolically active and play an important role in many physiological functions, including control of vasomotor tone, blood cell trafficking, vascular permeability, and maintenance of vascular integrity (Mensah, Vascul Pharmacol 46(5):310-314, 2007; Yetik-Anacak and Catravas, Vascul Pharmacol 45(5):268-276, 2006)...

Type B aortic dissection (TBAD) can be complicated due to visceral and limb malperfusion. We present the case of a patient with a TBAD 5 months after endovascular aneurysm repair (EVAR) for an infrarenal aortic aneurysm, which resulted in a right leg acute limb ischemia due to impingement of the EVAR from to the dissection. In the following discussion, we will review the literature and describe our technique for the treatment of this infrequent problem.
