background: the sentinel lymph node (sln) is defined as the first chain node in the lymphatic basin that receives primary lymphatic flow. if the sln is negative for metastatic disease, then other nodes are expected to be disease-free. sln techniques have been extensively applied in the staging and treatment of many tumors, including melanoma, breast and vulvar cancers. this study aims to evalua...

background: sentinel lymph node biopsy (slnb) has replaced axillary lymph node dissection (alnd) in early breast cancer patients as the first line surgical approach to axillary nodes. further dissection is performed only when sln is involved by tumor cells. however, in a significant proportion of patients, non-sentinel nodes are still not involved and axillary dissection has no additional thera...

Nach einer Einleitung und Diskussion tiber die Eingen­schaften der diabetischen Krankheiten wurde ausflihrlich trber die Aetiologie und Pathophysiologie der Zuckeran­kheiten,insbesondere der Altersdiabetis,gesprochen.Nach der symptomalogie der Diabetis haben wir die ncueste Einteilung der Zuckerkrankheiten genannt und die Untc­rsuchungsmethoden,die heute Uhlich sind,erwahnt;dazu wurden unsere M...

Sensor webs consisting of nodes with limited battery power and wireless communications are deployed to collect useful information from the field. Gathering sensed information in an energy efficient manner is critical to operate the sensor network for a long period of time. In [3] a data collection problem is defined where, in a round of communication, each sensor node has a packet to be sent to...

background: in this study we evaluated the prognostic impact of metastatic lymph node ratio (mlr) in patients with gastric cancer undergoing curative surgical resection. methods: a total of 121 patients with gastric adenocarcinoma undergoing curative r0 surgical resection in our institutions between 2003 and 2010 were included in this study.  mlr was classified into 3 groups as follows: mlr0; 0...

In present energy efficient protocols for mobile ad hoc networks, once the route is selected in the route discovery phase, the selected route is used until all the data packets are sent out or until the selected route fails due to the exhaustion of node battery energy. Due to the continuous flow of the packets through a selected route, and if a node in that route having less battery energy, the...

meningioma is usually a benign central nervous system (cns) tumor. metastasis is rare; however if it does occur the most metastatic sites are the liver and lungs. here, two cases of cns meningioma with metastasis to cervical lymph nodes are reported. the first case, a 48 year-old man developed cervical lymph node metastasis nine years after primary tumor diagnosis. the second case, a 23 year-ol...

The paper discusses diierent approaches to the analysis of nite verb position in German within the framework of HPSG. It argues that among three parameters (a) standard subcatego-rization and adjunction, (b) uniform structural representation and (c) clause initial nite verbs as heads, only two can be maintained simultaneously, unless additional devices are introduced. We abandon (c) and present...
