A 53-year-old woman complaining of vertical diplopia, presented with a localized swelling in the right lower lid. Magnetic resonance imaging studies demonstrated a relatively well-defined mass in the inferior rectus with similar signal characteristics to the muscle. Excisional biopsy of the mass revealed granular cell tumor composed of S-100 positive cells with acidophilic granular cytoplasm an...

The bulk rheology of bidisperse mixtures of granular materials is examined under homogeneous shear flow conditions using the event-driven simulation method. The granular material is modelled as a system of smooth inelastic disks, interacting via the hard-core potential. In order to understand the effect of sizeand mass-disparities, two cases were examined separately, namely, a mixture of differ...

Granular flow simulation using CFD has received a lot of attention in recent years. In such cases, CFD is either, coupled with Discrete Element Method (DEM) techniques for appropriate incorporation of inter-particle collisions, or the Eulerian CFD approach is used in which granular particles are treated as they were fluid. In the present study, a CFD analysis was performed...

Introduction: It is generally accepted that breast feeding has a beneficial effect on the health of infants and children. The evidence that breast feeding protects against obesity is inconclusive also the influence of breast feeding on blood pressure in later life is uncertain. The major aim of this study was to assess the association between method of infant breast feeding and components of t...

Synchronous bilateral breast cancer is rare, and oncocytic carcinoma is an even rarer breast cancer histological subtype. In general, oncocytic tumors are defined as neoplasms with eosinophilic granular cytoplasm and have been reported in various organs. Oncocytic carcinoma of the breast was first documented by Gădăleanu and Craciun in 1987, and 48 cases have since been reported. The present st...

Granular cell tumors are relatively uncommon benign lesions occurring in almost any part of the body. We report the cytological diagnosis of granular cell tumor in 25-year-old male patient who presented with an inguinal mass clinically suspected to be a lymphadenopathy. Fine needle aspiration revealed polygonal cells with abundant, granular cytoplasm and eccentrically located vesicular nuclei a...

background: there has been increasing trend towards surgical treatment of metastases across different cancer types, including breast cancer, in the recent decade. single metastasis of breast cancer to sternum is a rare situation. we present a case of sternectomy for metastasis from breast cancer. case presentation: a 58-year-old woman with a history of modified radical mastectomy for breast can...

Histiocytoid breast carcinoma (HBC) is a rare type of breast cancer with a controversial histogenesis. Here we describe a case report of a 65-year old woman with HBC. The patient presented with two masses in the right breast. Histopathologically, the tumors consisted of a diffuse infiltration of large tumor cells and histological components of carcinoma in situ and atypical lobular hyperplasia ...

[1] The partial fluidization model developed by Aranson and Tsimring (2002) is used to simulate the spreading of a 2D circular cap of granular material over an erodible bed made of the same material. Numerical results show that the presence of even a very thin layer of granular material lying on the solid bed strongly increases the mobility of granular flows. Furthermore, as the thickness of th...
