Endovascular Repair of Spontaneous Rupture of Stent Graft Branch in Thoracoabdominal Aortic Aneurysm-Management, Case Study, and Review.

Stent-graft implantation is a widely recognized method for endovascular treatment of aortic aneurysms. In cases where the aneurysm involves the thoracic and abdominal aorta, repair including fenestrated and branched stent grafts provides a viable alternative. This approach, initially reserved for patients unsuitable for open surgery, has become preferred for anatomically appropriate thoracoabdominal aortic aneurysms.

Desorption electrospray ionization-based imaging of interaction between vascular graft and human body.

The desorption electrospray ionization-mass spectrometry imaging (DESI-MSI) is known as a fast and convenient MS-based method for lipid imaging in various biological materials. Here, we applied this technique to visualize lipid distribution in a vascular graft removed from a patient's body. This is a good example of the DESI system capabilities toward imaging of interaction between artificial material and living tissues.

Cathepsin E (EC 3.4.23.34)--a review.

Cathepsin E belongs to the third class of enzymes - hydrolases, a subclass of peptide bond hydrolases and a sub-subclass of endopeptidases with aspartic catalytic sites. Cathepsin E is an endopeptidase with substrate specificity similar to that of cathepsin D. In a human organism, cathepsin E occurs in: erythrocytes, thymus, dendritic cells, epithelial M cells, microglia cells, Langerhans cells, lymphocytes, epithelium of gastrointestinal tract, urinary bladder, lungs, osteoclasts, spleen and lymphatic nodes.
