Infiltrating Angiosarcoma of the Ascending, Arch and Descending Aorta Manifested as Acute Mesenteric Ischemia.

Primary malignant aortic tumors are rare and aggressive. Most cases are diagnosed at advanced stages or during autopsies with a median overall survival of 8 months from diagnosis. We present the case of a 59-year-old male with angiosarcoma involving all segments of the thoracic aorta and a large floating thrombus causing acute mesenteric ischemia, which was treated successfully with embolectomy.

Hybrid Solution for Mycotic Pseudoaneurysm of Carotid Bifurcation.

Mycotic pseudoaneurysms of the extracranial carotid artery are rare and need surgical treatment to prevent rupture or embolization. We treated a case of a carotid bifurcation pseudoaneurysm secondary to infection caused by . We successfully treated it using a catheter balloon to obtain carotid bifurcation's control and replacing the carotid bifurcation with a vein graft.

Immobilisation and Release of Radical Scavengers on Nanoclays for Chemical Reinforcement of Proton Exchange Membranes.

Mechanical and chemical stability of proton exchange membranes are crucial requirements for the development of fuel cells for durable energy conversion. To tackle this challenge, bi-functional nanoclays grafted with amino groups and with embedded radical scavengers, that is, CeO nanoparticles were incorporated into Aquivion ionomer. The composite membranes presented high proton conductivity and increased stability to radical attack compared to non-modified Aquivion membranes, demonstrating the effectiveness of the approach based on radical scavenger immobilisation and release from clay nanocontainers.
