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...

The intraoperative mapping of sentinel lymph nodes (SLNs) is part of the treatment strategy for a number of types of tumor. To retrospectively compare results from the mapping of pelvic SLNs for gynecological oncology, using distinct dyes, the present review was conducted to determine the clinical significance of SLN mapping for gynecological oncology. In addition, the present study aimed at id...

PURPOSE To demonstrate the hemodynamic features of liver metastases using quantitative color mapping of the arterial enhancement fraction (AEF) and to investigate the feasibility of using the AEF to predict the chemotherapy response. MATERIALS AND METHODS Seventy-two patients with liver metastases (metastasis group) and 18 cancer-matched patients without liver metastases (non-metastasis group...

In this review, we discuss the emergence of the fourth-generation sequencing technologies that preserve the spatial coordinates of RNA and DNA sequences with up to subcellular resolution, thus enabling back mapping of sequencing reads to the original histological context. This information is used, for example, in two current large-scale projects that aim to unravel the function of the brain. Al...

we report the case of a 54-year-old iranian man who presented with melena from three months prior to admission. esophagogastroduodenoscopy and colonoscopy were normal. double balloon enteroscopy showed a pedunculated tumor located in the jejunum. he underwent laparotomy and resection of a 9.5 cm tumor from the distal jejunum. histopathologic evaluation confirmed the diagnosis of an inflammatory...

background: wilms' tumor is an emberyonal tumor arising from remnants of immature renal tissue. her2/neu is an onco-protein which mediates cellular proliferation, differentiation and survival. methods: in the current study, we analyzed her2/neu expression in 40 wilms' tumors. the clinico-demographic data of 40 patients with wilms' tumor were retrieved. immunohistochemical staining for her2/neu ...

the majority of osseous tumors of the hand are benign. the surgeon who evaluates and treats osseous tumors of the hand has to be familiar with limb anatomy, tumor biology, various presentations of the tumors and the range of treatment possibilities and their limitations. lesions in the hand more often present earlier in their course than those at other sites, just because they are more likely t...

A concept of weak $f$-property for a set-valued mapping is introduced‎, ‎and then under some suitable assumptions‎, ‎which do not involve any information‎ ‎about the solution set‎, ‎the lower semicontinuity of the solution mapping to‎ ‎the parametric‎ ‎set-valued vector equilibrium-like problems are derived by using a density result and scalarization method‎, ‎where the‎ ‎constraint set $K$...

In this Article, we give a simple criterion for the regularity of a tri-linear mapping. We provide if f : X × Y × Z −→ W is a bounded tri-linear mapping and h : W −→ S is a bounded linear mapping, then f is regular if and only if hof is regular. We also shall give some necessary and sufficient conditions such that the fourth adjoint D^∗∗∗∗ of a tri-derivation D is again tri-derivation.
