background: trace elements play an important role in a number of biological processes. astaxanthin (asx), a carotoid pigment found in certain marine plant and animals, has shown anti cancer and anti free radical properties. this work intended to understand the effect of astaxanthin in breast cancer (invasive ductal carcinoma, idc) by using micro-pixe method. for this aim the concentration of tr...

A useful approach to visualising the geographical distribution of web site hits is to geolocate the IP addresses of hits and plot them on a world map. In this paper we examine the efficacy of Google Earth for this purpose.

Objective: Inhibition of lipid metabolism in breast cancer has been suggested as an effective approach for cancer therapy. Saffron-derived crocetin (Crt) and crocin (Cro) with the known anticancer activity, have shown hypolipidemic effect in diabetes and atherosclerosis. Here, we investigated the effect of Crt/Cro on lipid content in breast cancer. Materials and M...

metastasis from breast cancer to other parts of the body is very common, but the spread of the tumor to pituitary gland, especially to infandibulum, is a rare presentation. at the time of pituitary metastasis, a majority of the patients have clinical and radiological evidence of the disease. it seems that the posterior area of the gland is the most common site of metastasis, probably due to hig...

Introduction: In external beam radiotherapy each effort is done to deliver 3D dose distribution onto the tumor volume uniformly, while minimizing the dose to healthy organs at the same time. Radiation treatment of tumors located at thorax region such as lung and liver has a challenging issue during target localization since these tumors move mainly due to respiration. There are...
