AIM To verify the current status of super-extended lymph node dissection for advanced gastric cancer according to a questionnaire survey. METHODS One-hundred and five institutions responded to the questionnaire. The survey included the following items: Number of experiences, whether performed prophylactically and/or therapeutically, whether preoperative chemotherapy was provided, number of pr...

introduction: several radiotracers are being used for sentinel node mapping in patients with breast cancer. in the current study, we reported our experience with 99m-tc phytate for sentinel node mapping in mashhad university of medical sciences. methods: all breast cancer patients who underwent sentinel node mapping using 99m-tc phytate were included. all patients received intradermal peri-areo...

Location information is one of the crucial and essential elements for monitoring data in wireless sensor networks. The distance vector-hop (DV-Hop) localization algorithm practical importance improving its performance. To achieve global optimization, a DV-Hop based on cyclotomic method weighted normalization, also known as CMWN-DV-Hop, nominated this paper. Therefore, segmentation weighting fac...

to review children with kawasaki disease admitted in 17-shahrivar hospital of rasht from 1999 to 2007. we reviewed retrospectively 64 children with kawasaki disease between 1999-2007 admitted in 17-shahrivar hospital of rasht. frequency distributions of variants including age, sex, season, clinical and laboratory manifestations, response to treatment and complications of the patients were abstr...

In this paper the properties of node-node adjacency matrix in acyclic digraphs are considered. It is shown that topological ordering and node-node adjacency matrix are closely related. In fact, first the one to one correspondence between upper triangularity of node-node adjacency matrix and existence of directed cycles in digraphs is proved and then with this correspondence other properties of ...

Lymphedema continues to be a very challenging clinical problem. While compression and physical therapy remain the foundation of treatment, recent advances in microsurgery super-microsurgery have allowed for development promising surgical options. One these options is vascularized lymph node transfer (VLNT), which has gained significant popularity over years. However, there no consensus on ideal...

We show that Karger’s randomized contraction method [7] can be adapted to multiobjective global minimum cut problems with a constant number of edge or node budget constraints to give efficient algorithms. For global minimum cuts with a single edge-budget constraint, our extension of the randomized contraction method has running time Õ(n3) in an n-node graph improving upon the best-known randomi...

In this paper, we investigate some economic fundamentals related to the Tezos blockchain platform under Emmy* consensus protocol. The protocol is based on a liquid version of Proof-of-Stake, in sense that users can temporarily delegate or all their Tz units full nodes. addition increasing stake node, and thus probability being selected as block baker/endorser, such delegation induces property s...

background : sentinel lymph node biopsy is a technique used to identify the axillary node most likely to contain tumor cells that have metastasized from a primary carcinoma of the breast. this technique provides accurate staging with fewer complications than axillary dissection and may result in decreased costs. we designed the present study to determine the accuracy and success rate of a combi...
