Background & Objective The role of synchronized expression pattern of cytokeratin (CK) 7 and CK20 in the prognosis of colon adenocarcinoma is unclear. The current study aimed at determining the relationship between the expression of cytokeratins 7 and 20 and prognostic factors in colon adenocarcinoma. Methods In the current cross sectional Study, 52 archival samples of colon adenocarcinoma wi...

BACKGROUND Post-traumatic anterior shoulder instability patients may present histopathologic lesions within the subscapularis muscle compatible with a scarring process associated with disuse atrophy. We hypothesized that such lesions identified on intraoperative biopsy at the time of primary anterior shoulder stabilization would predict a higher risk of postoperative instability recurrence. M...

Background & aim: Evaluation of prevalence of risk factors for breast cancer in different regions of Iran and identification of their significant effect on this disease can promote the prevention and reduction of breast cancer incidence. Therefore, this study aimed to evaluate the prevalence, demographic characteristics, and frequency of the risk factors of breast cancer during 10 years. Method...

drilling operations are exposed to a variety of hazards, some of which may be location and activity dependent and each could pose different risk from different paths.  drilling operation may be vulnerable to hurricanes in one region and be exposed to geohazards in another. however, there are other hazards, (e.g. corrosion, age degradation, poor maintenance), which equally affects every rig. ide...

The basis for a robust and accurate quantification is the segmentation of regions of interest (ROIs) defined by different histopathologic features. Several kinds of problems arise in ROIs segmentation of histopathologic images due to diverse factors such as: nonstationary and correlated noise, illumination, busyness of gray levels within the object and its background, inadequate contrast, among...

major salivary gland tumors are uncommon and the exact nature of these tumors is not obvious. this study was carried out to compare the histological results of intraoperative frozen sections against those of permanent reports for major salivary glands masses. one hundred thirty-nine patients with major salivary gland masses who were candidates for surgery underwent an intraoperative frozen sect...

BACKGROUND To identify the risk factors and assess the role of survivin in predicting progessivity precancerous cervical lesions. MATERIALS AND METHODS This case-control study was conducted from October 2009 until May 2010. We obtained 74 samples, classified according to the degree of cervical intraepithelial neoplasia (CIN): 19 samples for CIN 1, 18 samples for CIN 2, 18 samples for CIN 3, a...
