background: this study detected osteopontin (opn) and matrix metalloproteinase-7 (mmp-7) expressions to explore the roles of opn and mmp-7 in the occurrence, progression, and prognosis of nonsmall cell lung cancer (nsclc). materials and methods: a retrospective study was conducted on nsclc tissues ( n = 152; case group) and adjacent nonneoplastic lung parenchyma (adjacent to tumor >5 cm; n = 15...

Computer processing speeds are increasing rapidly due to the evolution of faster chips, parallel processing of data, and more eecient software. Users today have access to an unprecedented amount of high quality, high resolution data through various technologies. This is resulting in a growing demand for higher performance input and output mechanisms in order to pass huge data sets from the exte...

510 cases of surgical lymph node biopsies during a five year periode are reviewed with the following conclusionsthe lymph node biopsy constitues 5% of all the surgical biopsies, the cervical and axillary lymph nodes are the most commonly biopsicd nodes due to their easy accessibility and due to the fact that they drain the lymph from many vital organs: the next most commonly biopsied nodes are ...

among structured peer-to-peer systems, chord has a general popularity due to its salient features like simplicity, high scalability, small path length with respect to network size, and flexibility on node join and departure. however, chord doesn’t take into account the topology of underlying physical network when a new node is being added to the system, thus resulting in high routing latency an...

centralizing and using proper transportation facilities cut down costs and traffic. hub facilities concentrate on flows to cause economic advantage of scale and multimodal transportation helps use the advantage of another transporter. a distinctive feature of this paper is proposing a new mathematical formulation for a three-stage p-hub location routing problem with simultaneous pick-ups and de...
