Introduction: Malignant mesenchymal tumors of the larynx are rare. One type of malignant mesenchymal tumor is synovial sarcoma with unknown histogenesis, which occurs predominantly in the lower extremities of young adults. The head and neck region is a relatively rare location. There are few cases of malignant mesenchymal tumors with laryngeal localization in literature.  Case Report: In this r...

localization of sources in patients with focal seizure has recently attracted many attentions. in the severe cases of focal seizure, there is a possibility of doing neurosurgery operation to remove the defected tissue. the prosperity of this heavy operation completely depends on the accuracy of source localization. to increase this accuracy, this paper presents a new weighted beamforming method...

in addition to the liver, human hydatidosis has been reported in the lung, brain, abdominal viscera, muscles, and heart chambers. infarction of the brain has also been documented. arterial embolism of the lower extremities by hydatid cyst, however, is extremely rare. in the presented case, acute ischemia of the patient's left leg led to gangrene and amputation. complete workup for localiza...

The colon is a very rare metastatic localization. Here we report a case of colonic metastases from gastric adenocarcinoma whose clinical presentation was suggestive of a de novo adenocarcinoma of the ascending colon. The authors discuss that in the presence of a previous history of gastric cancer, immunohistochemical analysis on endoscopic biopsies may help in the definition of a differential d...

wireless sensor networks attracting a great deal of research interest. accurate localization of sensor nodes is a strong requirement in a wide area of applications. in recent years, several techniques have been proposed for localization in wireless sensor networks. in this paper we present a localization scheme with using only one mobile anchor station and received signal strength indicator tec...

conclusions radio-guided localization of non-palpable breast lesions is an acceptable method because of technical facilitation, accurate localization and complete excision with limited complications. so it can be recommended as an alternative method for wire-guided localization. results pathologic results were benign in 90.5% and malignant in 9.5% of patients. post-operative margin of lesion wa...
