Introduction: There is a consensus in the literature that sentinel lymph node biopsy is the standard procedure for axillary staging in early stage (I and II) breast cancer patients. Usually during lymphoscintigraphy, the location of the sentinel lymph node is marked on the skin by an indelible ink. In this study we evaluated this issue in our patients. Methods: 40 ...

background: sentinel node biopsy (slnb) is the standard of care for breast cancer treatment and it is getting wide acceptance in iran. the radiation safety of the procedure has been investigated under controlled conditions, but the standard dose of radiotracer and techniques are not always observed in the community setting. the aim of this study was to assess the magnitude of the absorbed doses...

endometrial adenocarcinoma is uncommon in fewer than 40-year-old people. the first common sign and symptoms are abnormal vaginal bleeding and discharge. metastasis is occurred in the late stage. here we present a 31-year-old nullipar woman who was admitted to surgical ward with enlarged right inguinal lymphnode from one month ago. she had no history of previous malignancy, infectious condition,...

In this study, a new and efficient approach is presented for numerical solution of Fredholm integro-differential equations (FIDEs) of the second kind on unbounded domain with degenerate kernel based on operational matrices with respect to generalized Laguerre polynomials(GLPs). Properties of these polynomials and operational matrices of integration, differentiation are introduced and are ultili...

‎In this paper‎, ‎we present a numerical method based on Bernstein polynomials to solve optimal control systems with constant and pantograph delays‎. ‎Constant or pantograph delays may appear in state-control or both‎. ‎We derive delay operational matrix and pantograph operational matrix for Bernstein polynomials then‎, ‎these are utilized to reduce the solution of optimal control with constant...

The concept of sums nonnegative circuit (SONC) polynomials was recently introduced as a new certificate nonnegativity especially for sparse polynomials. In this paper, we explore the relationship between and SONCs. As first result, provide sufficient conditions with general Newton polytopes to be SONC, which generalizes previous result on simplex polytopes. Second, prove that every SONC admits ...

It is shown that the zeros of the Faber polynomials generated by a regular m-star are located on the m-star. This proves a recent conjecture of J. Bartolomeo and M. He. The proof uses the connection between zeros of Faber polynomials and Chebyshev quadrature formulas.
