Monitoring of gene-expression profiles is assumed to refine tumor characterization of laryngeal squamous cell carcinomas (LSCCs) with a therapeutic perspective. This is especially expected for adhesion/growth-regulatory effectors such as galectins, a class of endogenous lectins. Using computer-assisted microscopy, we investigated the prognostic value contributed by the quantitative determinatio...
Background: Fine-needle aspiration of breast cancer often provides moderate cellular material that is representative of the tumors. These samples can be used not only for cytological diagnosis but also to obtain information on the prognosis and likely response to therapy by using immunohistochemical staining studies. Methods: We assessed the degree of correlation between prognostic biologic ma...
Purpose: The development of sensitive and non-invasive biomarkers for the early detection CRC determination their role in individual stages CRC. Methods: MMP-9 expression serum tissue, BDNF plasma were detected using ELISA method. tissue also determined by immunohistochemical staining. Results: To assess balance between changes survival tumor progression, we compared BDNF/MMP-9 ratios tissues l...
the calcifying odontogenic cyst (coc) is a rare odontogenic cyst. only 2% of all odontogenic cysts and tumors are coc. coc associated with odontoma (cocao) reported in 24% of cocs. cocao presents a greater incidence in female, with a ratio of 2 to 1. the highest incidence of cocao occurs during the second decade with a mean age of 16 years, most frequently occurring in the maxilla (61.5%). here...
in this study, a simple, rapid and selective method was developed for the determination of dexamethasone. the proposed method is based on inhibitory effect of dexamethasone on the oxidation of orange-g by bromate in sulfuric acid media. the reaction was followed spectrophotometrically at 478.5 nm (?max). under optimum experimental conditions, (72.6 ?mol l-1 of orange-g, 0.76 mol l-1 of h2so4, 0...
Neisseria meningitidis remains the leading cause of fatal sepsis. Cultures may not be available in fulminant fatal cases. An immunohistochemical assay for N meningitidis was applied to formalin-fixed samples from 14 patients with meningococcal disease. Histopathologic findings in 12 fatal cases included interstitial pneumonitis, hemorrhagic adrenal glands, myocarditis, meningitis, and thrombi i...
The present study was designed to evaluate the pathological and immunohistochemical findings of Mycobacterium avium intracellulare complex (MAC) lung infection. A retrospective study was performed in five cases with positive cultures for MAC in whom lung resections were performed between January 1989 and December 1996. A determination of whether or not MAC caused pulmonary disease was made usin...
