We report an unexpectedly rich variety of new flow patterns on a granular heap that is centrifuged so as to simulate the reduction in gravity. These surface patterns exhibit coexisting static and flowing regions that depend strongly on centrifugal stress, but surprisingly not on mass flow rate. A discrete cellular automaton model reproduces some of the patterning features and indicates that sub...

Background: Prognosis and management of breast cancer are defined by different variables including histological type, grading, clinical stage, Her2+, estrogen and progesterone receptor conditions. Generally, mammography is one of the most important imaging which is done in breast cancer patients. The aim of this research was to evaluate different mammographic patterns in different breast cancer...

sarcomas of the breast are rare and comprise less than 1% of mammary cancers. myxofibrosarcoma as an unusual variant of malignant fibrous histiocytoma in the breast and during pregnancy has not previous been reported in the literature. we present the case of a 32-year-old woman with a rapidly growing subcutaneous left breast mass that appeared during her first pregnancy. after ultrasonography a...

Male breast cancer is one of the rare malignancies. Clinically it usually a fixed mass in the breast in the seventh decade of life. Metabolic disorders and gyneco­mastia and Klinefelter's syndrome are important predis­r,osing factors.  Primary management is simple mastectomy plus re­gio:ial lymph node irradiation. In late cases or metastatic disease, orchidectomy, adrenalectomy, and hypophysec...

idiopathic lobular grunulomatous mastitis is a chronic inflammatory disease of breast that can clinically mimic brent carcinoma or pyogenic abscess. the most common clinical presentation is a fine unilateral discrete mass associated inflammation of overlying skin. nipple retraction and sinus formation are present. breast tb should be considered in differential we present a few cause of our cent...

background: angiosarcoma can develop in all parts of the body containing blood vessels, including breast. statistically, less than 10% of all angiosarcomas originate in the breast. angiosarcoma accounts for less than 0.05% of breast primary cancers. primary angiosarcoma develops without a history of treatment for breast cancer, whereas secondary angiosarcoma develops in patients who have alread...

 ABSTRACTWe are reporting a 43-year-old female breast cancer case with a solitary metastatic adenocarcinoma in clivus. This patient with a stage II (T1N1M0) breast cancer history has been followed for 7 years.  Modified Radical Mastectomy (MRM) and 6 courses chemotherapy with CMF (Cyclophosphamide, Metotrexate, 5FU) regimen were done for her at the time of diagnosis. Also, she took tamoxifen tw...

A diversity of animals that run on solid, level, flat, non-slip surfaces appear to bounce on their legs; elastic elements in the limbs can store and return energy during each step. The mechanics and energetics of running in natural terrain, particularly on surfaces that can yield and flow under stress, is less understood. The zebra-tailed lizard (Callisaurus draconoides), a small desert general...
