BACKGROUND: Widespread infiltration of tumor cells into surrounding brain parenchyma is a hallmark of malignant gliomas, but little data exist on the overall invasion pattern of tumor cells throughout the brain. METHODS: We have studied the invasive phenotype of malignant gliomas in two invasive mouse models and patients. Tumor invasion patterns were characterized in a patient-derived xenograft mouse model using brain-wide histological analysis and magnetic resonance (MR) imaging...

Salmonella spp. are health-threatening foodborne pathogens. The increasingly common spread of antibiotic-resistant Salmonella spp. is a major public healthcare issue worldwide. In this study, we wished to explore (1) antibiotic or polypeptide combinations to inhibit multidrug-resistant Salmonella bredeney and (2) the regulation of cross-resistance and collateral sensitivity of antibiotics and polypeptides. We undertook a study to select antibiotic combinations. Then, we promoted drug-resistant strains of S...

Carotid rete mirabile is an arterial meshwork, occurring at the cavernous portion of the internal carotid artery (ICA). Rete mirabile in humans is not present during normal development of the intracranial circulation and hence is considered as a collateral pathway that develops as a consequence of segmental agenesis of the ICA. We report three cases of this rare entity encountered at our institute.

BACKGROUND AND IMPORTANCE: Aneurysms of the ophthalmic artery (OA) within the orbit and optic canal are extremely rare. Given the peripheral location of these aneurysms and the fact that most are fusiform, parent artery occlusion is preferred for symptomatic aneurysms. However, the impact of OA occlusion on vision is not always innocuous. Balloon occlusion testing (BOT) of the OA has the potential to gauge the possibility of visual compromise, in addition to assessing collaterals. While BOT has been assessed for carotid artery occlusion, its role in OA occlusion has not been well defined...

Familial partial lipodystrophic syndrome 3 (FPLD3) is associated with mutations in the transcription factor PPARγ. One of these mutations, the P467L, confers a dominant negative effect. We and others have previously investigated the pathophysiology associated to this mutation using a humanised mouse model that recapitulates most of the clinical symptoms observed in patients when phenotyped under different experimental conditions. One of the key clinical manifestations observed both, in humans and mouse models, is the ectopic accumulation of fat in the liver...

The recent availability of different transgenic mouse lines coupled with other modern molecular techniques has led to the discovery of an unexpectedly large cellular diversity and synaptic specificity in striatal interneuronal circuitry. Prior research has described three spontaneously active interneuron types in mouse striatal slices; the cholinergic interneuron, the neuropeptide Y-low threshold spike interneuron, and the tyrosine hydroxylase interneurons (THINs). Using transgenic Htr3a-Cre mice we now characterize a fourth population of spontaneously active striatal GABAergic interneurons termed spontaneously active bursty interneurons (SABI) because of their unique burst-firing pattern in cell-attached recordings...

Background Dissection of the internal carotid artery (ICA) can cause occlusion or severe stenosis and is known to be one of the major causes of ischemic stroke in the young. Endovascular treatment is one of the useful options for carotid dissections, but passing the guidewire through the occlusion (lesion-cross) and confirmation of the true lumen are sometimes difficult. Case presentation A 40-year-old right-handed man complaining of dysarthria and gait disturbance consulted our hospital. Magnetic resonance imaging and angiography revealed right ICA dissection...

BACKGROUND: Numerous conditions that affect the boundary between the aortic arch and descending aorta are treated with thoracic endovascular aortic repair (TEVAR). In 40 % of cases, coverage of the left subclavian artery (LSA) cannot be prevented. Subsequently, neurological complications such as stroke or ischemia of the left upper extremity may develop. However, the actual risk of these complications is subject to considerable controversy. The optimal treatment approach, specifically the question whether primary revascularization of the LSA should be performed in all cases, is unclear...

Pial synangiosis is a method of indirect surgical revascularization developed at our institution for the treatment of moyamoya disease in pediatric patients. Similar surgical principles are employed in adult cases, often performed because of lack of an adequate donor vessel. Standardized protocols, including preadmission for preoperative intravenous hydration and aspirin administration, as well as intraoperative electroencephalography, are routinely employed to minimize operative risk. Perioperative heparinization is not required...

BACKGROUND AND AIMS: YKL-40 is an inflammatory marker secreted by macrophages and is expressed in atherosclerotic plaques. YKL-40 increases in coronary artery disease (CAD) with poor coronary collateral vessel development. Higher levels are linked to reduced survival in CAD patients. Studies evaluating YKL-40 in patients with peripheral arterial disease (PAD) are scarce. This study aims to elucidate a possible link between YKL-40 and PAD severity as well as cardiovascular long-term mortality...
