introduction: size of axillary lymph nodes can be a predictor for breast abnormalities. the agents in the antiperspirants such as aluminum were observed in the breast biopsy of individual with abnormalities and antiperspirants usage. in this study, the relation between using antiperspirants and the size of axillary lymph nodes were evaluated in iranian women. methods: in this study, 120 women w...

the imaging assessment of nodal disease can be challenging for the radiologist because there are multiple sites to review and differing opinions about criteria for abnormal nodes. the ability to accurately detect nodal metastases is improved with knowledge of the criteria for abnormal nodes, the nodal drainage patterns, and common imaging pitfalls. in this article, we introduce these basic conc...

the most common metastatic sites for colorectal carcinomas include the liver, lungs, brain, bones and peritoneal surfaces. in this report, a case of sigmoid colon carcinoma presented with cervical lymphadenopathy was detected with the help of pet/ct. a 57 year-old male presented with a complaint of swelling on the left side of his neck. ultrasonographic examination of the neck revealed three hy...

Aimed at the low precision and scalability of synchronization protocol in wireless sensor networks (WSNs), this paper proposes a clock self-synchronization protocol based on distributed diffusion (DDCSS). According to the energy, distribution and the average transmission delay of nodes, DDCSS chooses a set of master-node and diffusion-nodes which are used to perform local diffusion in each roun...

This paper proposes an efficient network architecture to improve energy consumption in Wireless Sensor Networks (WSN). The proposed architecture uses a mobile data collector to a partitioned network. The mobile data collector moves to center of each logical partition after each decision period. The mobile data collector must declare its new location by packet broadcasting to all sensor node...

background and objectives: involvement of lymph nodes is an important prognostic factor in the most cancers, including colorectal cancer. in the recent years, invasion to blood and lymphatic vessels has been shown to predict involvement of lymph nodes and the number of involved nodes has been less studied issue. the aim of this study was determination of the relationship between the size of col...

Background: The purpose of this study was to assess the dose distribution and coverage of level Ⅰ-Ⅱ axillary lymph nodes during whole breast tangential field radiotherapy (RT) after breast-conserving surgery in patients with breast cancer. Materials and Methods: The level Ⅰ-Ⅱ axillary lymph node volumes were retrospectively contoured by a single radiation oncologist based on computed tomography...

in recent years, artificial neural networks (anns) have been widely used for flood esti-mation. in this study, an ann model based on the geomorphologic characteristics of a watershed such as the number of possible paths and their probabilities is developed (gann model). nodes in the input layer are allocated to the surface flows, subsurface flows, excess-rainfall and infiltrated rain. the numbe...
