introduction: several radiotracers are being used for sentinel node mapping in patients with breast cancer. in the current study, we reported our experience with 99m-tc phytate for sentinel node mapping in mashhad university of medical sciences. methods: all breast cancer patients who underwent sentinel node mapping using 99m-tc phytate were included. all patients received intradermal peri-areo...

A method of estimating the magnitude and distribution of umbilical blood flow by means of radioactive microspheres in sheep fetuses in utero is described. Simultaneous measurements of total umbilical flow by this method and the steady-state diffusion technique showed agreement within ± 11%. In 11 fetuses of 90 to 150 days gestational age, the distribution of umbilical flow to the intercotyledon...

to review children with kawasaki disease admitted in 17-shahrivar hospital of rasht from 1999 to 2007. we reviewed retrospectively 64 children with kawasaki disease between 1999-2007 admitted in 17-shahrivar hospital of rasht. frequency distributions of variants including age, sex, season, clinical and laboratory manifestations, response to treatment and complications of the patients were abstr...

In this paper the properties of node-node adjacency matrix in acyclic digraphs are considered. It is shown that topological ordering and node-node adjacency matrix are closely related. In fact, first the one to one correspondence between upper triangularity of node-node adjacency matrix and existence of directed cycles in digraphs is proved and then with this correspondence other properties of ...

With the spread of pollinosis caused by sugi (Japanese cedar, Cryptomeria japonica) pollen, use pollen-free somatic seedlings is expected in Japan. However, there a lack knowledge on relationship between abilities during embryogenesis, initial vitro growth traits, and subsequent seedlings. In present study, we provide first basic information embryo maturation efficiency, germination, plantlet c...

background : sentinel lymph node biopsy is a technique used to identify the axillary node most likely to contain tumor cells that have metastasized from a primary carcinoma of the breast. this technique provides accurate staging with fewer complications than axillary dissection and may result in decreased costs. we designed the present study to determine the accuracy and success rate of a combi...

  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,...

Nitraria schoberi (Ghar-e-Daghin in Persian) from Zygophyllaceae (Nitrariaceae) family is considered as a wonderful exquisite plant in terms of its economical, medicinal, animal feed, significant values and also its unique characteristics of being tolerant to the soil salinity, drought and erosion. On the other hand, this plant is challenging with severe problems such as seed dormancy, plant gr...
