Patients undergoing endovascular repair (EVAR) of aortoiliac or iliac artery aneurysm may require sacrifice of one or both internal iliac arteries (IIAs). Until Food and Drug Administration-approved commercial grafts became available, endovascular IIA preservation was accomplished using the "sandwich" technique, but limited information is available regarding the results of this method. After ob...

Nasal-type, extranodal NK/T cell lymphoma (ENKTCL) is a special type of lymphomas with geographic and racial specificity. Up to now, the standard first-line treatment is still not unified. In our previous report, the "sandwich" protocol produced good results. Continuing to use the "sandwich" mode, a new chemotherapy composed of L-asparaginase, cisplatin, etoposide and dexamethasone (LVDP) plus ...

Abstract Aluminum foam sandwich (AFS) is an innovative material combination for designing lighter products and has many advantages such as a high bending stiffness at low density good energy absorption properties. Although the ready series production, number of industrial applications because costs material, lack design knowledge missing reference applications. This paper focuses on aspect how ...

sandwich panels as composite materials have two external walls of either metallic or polymer type. the space between these walls is filled by hard foam or other materials and the thickness of different layers is based on the final application of the panel. in the present work, the extent of variation in core density of polyether urethane foam and subsequent flexural and compressive changes in s...

introduction: breast cancer is one of the provalent cancers in the world. this cancer as well as other solid tumors, in the course of its development has phases in this order: epithelial dysplasia, carcinoma insitu, invassiveness and metastasis. breast cancer diagnosis is generally made with pathology methods. in this survey, measuring angiostatin (which is one of the most important and potent...

A coalgebraic, equational approach to the speci(cation of observational structures allowing for a choice in the result type of observations is presented. Observers whose result type is structured as a coproduct of basic types are considered, and notions of covariable, coterm and coequation, dual to the algebraic notions of variable, term and equation are used to specify the associated structure...
