quantum dots are new types of fluorescent materials for biological labeling. as a result, qds toxicity study is an essential requirement for future clinical applications. therefore, the cytotoxic cdse:zns quantum dots effects on some organs in mice are presented in this study. in this work, 10, 20 and 40 mg/kg doses of cdse:zns quantum dots were injected to 32 adult male mice. structural and op...
Among pancreatic cystic lesions, mucinous neoplasm (MCN) and intraductal papillary (IPMN) of the pancreas are precursor lesions adenocarcinoma. IPMN is characterized by proliferation mucin-producing epithelial cells that exhibit various degrees dysplasia. classified as main duct type (MD-IPMN), mixed branch (BD-IPMN) according to location involvement, into four histological subtypes (gastric, i...
AIM To determine the proportion of women with abnormalities in cervical smears corresponding to borderline nuclear change, as defined by national guidelines, which return to normal or persist as cytological or histological abnormalities. METHODS 313 women with borderline nuclear change diagnosed by a single pathologist using the national criteria were followed up for up to two years. RESULT...
BACKGROUND Although re-assessment of proliferative activity by K67 evaluation during the course of neuroendocrine neoplasms (NENs) is recommended in selected patients, its impact on patients' management is not clear due to the lack of data supporting this practice. AIM To investigate Ki67 change at time of progressive disease (PD) in entero-pancreatic NENs (EP-NENs). PATIENTS AND METHODS Re...

While clinical and pathologic responses are important prognostic parameters, biological markers from core needle biopsy (CNB) are needed to predict neoadjuvant chemotherapy (NAC) response, to individualize treatment, and to achieve maximal efficacy. We retrospectively evaluated the cases of 183 patients with primary breast cancer who underwent surgery after NAC (anthracycline and taxane) at the...
A case of endometriosis presenting as a mass in the groin of a pregnant woman is described. The mass increased in size during the pregnancy and the radiological features were suspicious of malignancy. Histological examination showed atrophic glands set in an abundant stroma. This was not typical of normal endometrial stroma but had a pronounced myxoid appearance with areas of decidualization. T...
Cadherins and catenins, mediators of intercellular interactions, play a major role in adhesion. Changes in their expression and functioning reflect invasive and metastatic properties of cancer cells. The study objective was to assess changes in the expressions of E-cadherin and alpha-, beta- and gamma-catenin proteins in pancreatic duct carcinoma in correlation with clinicopathological paramete...
