background: recent epidemiological studies demonstrate that obesity is associated with an increased risk for breast cancer in women. increased estrogen levels are suggested as one possible explanation, but this does not fully explain the relationship between obesity and breast cancer. one alternative explanation is secretion by adipocytes of metabolites, hormones and cytokines, collectively kno...

in order to increase the efficiency of the conveyance of the granular solids, a new experimental set-up is designed. the test rig has longitudinal trapezoidal slots in its conveying pipes. through experimentation, a correlation for friction factor in terms of solid mass flow rate, fluid flow rate and froude number is presented. it is shown that the mixture friction factor for pipes with inner t...

Granular cell tumors (GCTs) are rare soft tissue neoplasms and occur in different parts of the body. We report a case of granular cell tumour of common bile duct (CBD) in a 39 years old lady, presenting with obstructive jaundice. Magnetic resonance cholangiopancreatography (MRCP) showed it as a benign looking mass in CBD. Complete surgical excision of the tumour was done. Histopathology was con...

Oncocytoma is a rare benign salivary gland tumor, which mostly occurs in the parotid gland. In this article, we describe an early onset of oncocytoma of minor salivary gland in a 36-year, white male. On clinical examination, we encounter with a painless, granular, sessile mass. After Excisional biopsy, the histopathological features revealed sheets of cells with abundant granular eosinophilic c...

Granular cell myoblastomas are uncommon, typically benign tumors. Involvement of the esophagus is rare, and frequently they are asymptomatic. We report a granular cell myoblastoma involving the cervical esophagus in a patient who had paralysis of the true vocal cord and progressive dysphagia. At MR imaging, the circumscribed mass was hypointense on T1-weighted images and mildly hyperintense on ...

conclusion the possibility of malignancy is strongly indicated when additional nme lesions show linear or segmental enhancement on preoperative 3t dce-mri in patients with recently diagnosed breast cancer. results on histopathologic analysis of the 88 nme lesions, 73 (83%) were malignant and 15 (17%) were benign. lesion size did not differ significantly between malignant and benign lesions (p =...

since mammography images are in low-contrast, applying enhancement techniques as a pre-processing step are wisely recommended in classification of the abnormal lesions into benign or malignant. a new kind of structural enhancement is proposed by morphological operator which introduces an optimal gaussian kernel primitive, the kernel parameters are optimized the use of genetic algorithm­­. we al...

BACKGROUND Glycogen-rich carcinoma is a rare special histologic subtype of breast cancer and its incidence is estimated to be 1.4% in breast malignancies. However, its precise characteristics in cytological specimens have not yet been fully clarified. CASE Fifty-nine-year-old and 53-year-old women underwent fine-needle aspiration biopsy cytology (FNABC) of a breast tumor, confirming malignanc...

Apocrine carcinoma of the male breast is an exceptional malignant tumor. It does not have a particular clinical or radiological appearance, but it's microscopically characterized by the presence of granular cells and foamy cells representing over 90% of tumor cells. These cells express most of the time the GCDFP-15 and the androgen receptors. This tumor is a distinct molecular entity. In this o...

During hazardous geophysical mass flows, such as rock or snow avalanches, debris flows and volcanic pyroclastic a continuous exchange of material can occur between the slide bed. The net balance erosion deposition particles drastically influence behaviour these flows. Recent advances in describing non-monotonic effective basal friction internal granular rheology depth averaged theories have ena...
