    Notes: Background:  Insulin-like growth factor-1 (IGF-1) is one of the most critical proteins required for the survival, migration, and growth of melanoma cells. IGF-binding protein 2 (IGFBP2), which binds and regulates the function of IGF-1, is upregulated in a dose-dependent manner in melanoma cells treated with IGF-1, suggesting a possible role of IGFBP2 in the pathogenesis of melanoma.Methods:  Tissue microarrays were constructed using formalin-fixed, paraffin-embedded archival tissue blocks from 94 melanocytic lesions: 20 benign nevi, 20 dysplastic nevi, 23 primary melanomas, and 31 metastatic melanomas. IGFBP2 expression was evaluated immunohistochemically using a polyclonal antibody against the C-terminus of IGFBP2. The number of cells and labeling intensity were assessed semiquantitatively.Results:  Positive IGFBP2 labeling was observed in 5.0% of benign nevi, which was significantly lower than in dysplastic nevi (35.0%), primary melanomas (52.2%), or metastatic melanomas (54.8%) (p 〈 0.05). Among the IGFBP2-positive cases, moderate-to-strong immunostaining was observed in 64.7% of metastatic melanomas and 33.3% of primary melanomas. But none of the dysplastic nevi had moderate-to-strong immunostaining (p 〈 0.05).Conclusions:  Our study shows that IGFBP2 expression increases from benign and dysplastic nevi to primary and metastatic melanomas and suggests that it may play a role in melanoma progression.

    Real-time Polymerase Chain Reaction for the Food Microbiologist: Technologies, Applications, and Limitations (2005)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 70 (2005), S. 0

    Notes: : Rapid detection of pathogenic and spoilage microorganisms is essential for ensuring the safety and quality of food. Real-time polymerase chain reaction (PCR) technology has the potential to achieve rapid, sensitive, and specific detection of these microorganisms in food. In this review, we discuss real-time PCR technologies in use today, applications of real-time PCR in food systems, and some of the associated challenges and limitations.

    A three-tiered approach to differentiate Listeria monocytogenes biofilm-forming abilities (2003)
    Oxford, UK : Blackwell Publishing Ltd
    FEMS microbiology letters 228 (2003), S. 0 
    Details
    ISSN: 1574-6968
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: The purpose of this research was to develop a system for cultivating and evaluating Listeria monocytogenes biofilms that produces consistent and reliable results. A three-tiered approach was used to evaluate biofilm-forming abilities of three L. monocytogenes strains that were originally associated with listeriosis outbreaks. A L. monocytogenes‘honeycomb’ biofilm structure was described. L. monocytogenes strains Scott A and V7 were comparable in developing biofilm network structures and F2365 was less effective in forming biofilm. This three-tiered method can be very useful for further biofilm studies.

    Melatonin-selenium nanoparticles inhibit oxidative stress and protect against hepatic injury induced by Bacillus Calmette–Guérin/lipopolysaccharide in mice (2005)

    Notes: Abstract:  Melatonin-selenium nanoparticles (MT-Se), a novel complex, were synthesized by preparing selenium nanoparticles in melatonin medium. The present investigation was designed to determine the protective effects of MT-Se against Bacillus Calmette–Guérin (BCG)/lipopolysaccharide (LPS)-induced hepatic injury in mice. In BCG/LPS-induced hepatic injury model, MT-Se administered (i.g.) at doses of 5, 10, or 20 mg/kg to BCG/LPS-treated mice for 10 days, significantly reduced the increase in plasma aminotransferase, reduced the severe extent of hepatic cell damage and the immigration of inflammatory cells. The MT-Se particles also attenuated the increase in the content of thiobarbituric acid-reactive substances and enhanced the decrease in reduced activities of superoxide dismutase and glutathione peroxidase (GPx). However, treatment with MT-Se suppressed the increase in nitric oxide levels both in plasma and liver tissue. Furthermore, supplementation with MT-Se at the dose of 10 mg/kg (composed of 9.9 mg/kg melatonin and 0.1 mg/kg selenium) had great capability to protect against hepatocellular damage than a similar dose of melatonin (10 mg/kg) or selenium (0.1 mg/kg) alone. This effect may relate to its higher antioxidant efficacy in decreasing lipid peroxidation and increasing GPx activity. These results suggest that the mode of MT-Se hepatic protective action is, at least in part, related to its antioxidant properties.
