Introduction: The applicability of sentinel lymph node biopsy for early detection of metastasis in patients with renal cell carcinoma (RCC) is still in the validation phase and under investigation, which might be due to the unpredictability of the lymphatic pattern in RCC. In this study, we aimed to evaluate the feasibility and accuracy of sentinel node biopsy in patients with ...

breast cancer is a major cause of mortality in women due to malignant diseases and is the most prevalent type of cancer in western countries. according to investigations which has been done in iran so far, the prevalence of disease in our country is also very high, therefore complete attention to clinical and pathological findings of this disease would be extremely essential. in this study, the...

introduction: recent studies have shown acute cardioprotective effects of cyclosporine. the aim of the present study was to determine the protective role of cyclosporine on the model simulated the rotational nodal arrhythmia (avnrt) by using extracellular field potential recordings of isolated atrioventricular-node (av-node) of rabbit. methods: this study was performed on isolated double-perfus...

background: cd8+ cytotoxic t lymphocytes have been recently divided based on their cytokine expression profile. objective: to evaluate the percentages of cd8+ lymphocytes and their effector subsets including tc1, tc2 and tc17 in the tumor draining lymph nodes (tdlns) of patients with breast cancer. methods: single cell suspensions were obtained from tdlns of 42 patients with breast cancer. stai...

introduction kawasaki disease (kd) is an acute systemic vasculitis, of unknown etiology, that mainly affects infants and young children. although originally thought to be a benign illness, kd may prove fatal, especially if the diagnosis is delayed due to a nonclassic presentation. case presentation here, we present the case of a 4-year-old girl with a history of prolonged fever. her physical ex...

Background: Breast cancer is the most commonly diagnosed and the leading cause of cancer death among females worldwide. The rate of breast cancer incidence among Iranian women is 17% of all cancers, it has been ranked first in Iran. This study aimed to investigate the factors affecting axillary lymph node involvement in female patients with breast cancer. Methods: A cross-sectional study was c...

it is well know that any three impedances or admittances connected into each other in a star form can be easily transformed to a new three impedances or admittances connected into each other in a mesh form. in this paper a generalization of this fact is established and it is shown that in an n + 1 node network which is connected in a form it is always possible to eliminate the center node and o...

we reported a 35 year old breast cancer patient who was referred to our nuclear medicine department for sentinel node mapping. she was planned to undergo mastectomy and lymphatic mapping. a dose of tc-99m phytate was injection in the peri-areolar region in an intra-dermal fashion. two hours post-injection no sentinel node was visible in the axilla. due to a high liver uptake, inadvertent intra-...

we study the limiting distribution of the degree of a given node in a scaled attachment random recursive tree, a generalized random recursive tree, which is introduced by devroye et. al (2011). in a scaled attachment random recursive tree, every node $i$ is attached to the node labeled $lfloor ix_i floor$ where $x_0$, $ldots$ , $x_n$ is a sequence of i.i.d. random variables, with support in [0,...

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 patients with the clinical dia...
