Alterations in transcriptional control may contribute directly to can. inogenesis. Using the differential display technique in prostate cancer cells compared to normal prostate epithelial cells, we identified a down-regu lated gene and an up-regulated gene in cancer cells. The down-regulated gene encodes human epithelial tropomyosin (TMel), a member of the family of actin filament-binding prote...

Giant unilamellar vesicles are a widely utilized model membrane system, providing free-standing bilayers unaffected by support-induced artifacts. To measure the lamellarity of such vesicles, fluorescence microscopy is one commonly utilized technique, but it has the inherent disadvantages of requiring lipid staining, thereby affecting the intrinsic physical and chemical properties of the vesicle...

Abstract Introduction Amyloidosis and Behcet's syndrome (BS) are systemic diseases that affect multiple systems. Similar mucocutaneous damage occurs in amyloidosis BS, thus causing a delayed or incorrect diagnosis. The prognosis of patients with is poor. Therefore, exclusion other diagnoses important before confirming the presence BS. Case Report We report case 43‐year‐old woman who initially p...

AIM To establish the staining characteristics of certain ion exchange resins in histological material, with a view to enabling confident differential identification. METHODS Various histological staining procedures were applied to selected pathological material and prepared agar blocks containing the cation exchange resin calcium polystyrene sulphonate and the anion exchange resin cholestyram...

OBJECTIVES To evaluate CD200 expression in B-cell proliferative disorders. METHODS We analyzed 180 recent specimens of B-cell neoplasms for CD200 expression by flow cytometric immunophenotypic analysis, which is better able to assess relative intensity of staining than immunohistochemical staining. RESULTS We found that hairy cell leukemia exhibits a high level of staining for CD200 in comp...

background and aims. the aim of this study was to evaluate the effect of different etching times on enamel color stability after immediate versus delayed exposure to colored artificial saliva (cas). materials and methods. human first premolars were divided into five groups of twenty. a colorimeter was used according to the cie system on the mid-buccal and mid-lingual surfaces to evaluate initia...

Solitary fibrous tumors (SFTs) have been shown to harbor the characteristic NAB2-STAT6 gene fusion. Some recent studies have suggested that STAT6 is a useful marker for the diagnosis of SFTs. The aim of this study was to evaluate the diagnostic value of monoclonal anti-STAT6 in the distinction of SFTs from histologic mimics. The expression of STAT6 was evaluated in tissue microarrays and in who...

In this study, the purposes were to compare the staining methods for detection of glycoprotein profiles in normal and lung cancer serum samples and to preliminary screen the carbohydrate specificity of glycoproteins in both serum samples. Using the sequential staining methods of Pro-Q Emerald 488 glycoprotein gel staining, SYPRO® Ruby staining and silver staining revealed that the Emerald 488 g...

BACKGROUND Immunohistochemical staining for cluster designation 5 (CD5) has been found to label a variety of non-lymphoid tumors. METHODS A variety of eccrine, apocrine, follicular, epithelial, and pagetoid lesions were selected and stained with an anti-CD5 monoclonal antibody (Novocastra Labs, Newcastle upon Tyne, UK, clone 4C7) by immunohistochemistry. The intensity of positive cytoplasmic ...
