    4′,5′-Dibromo-2′,7′-dinitrofluorescein, a red dye commonly referred to as eosin B, inhibits Toxoplasma gondii in both enzymatic and cell culture studies with a 50% inhibitory concentration (IC50) of 180 μM. As a non-active-site inhibitor... of the bifunctional T. gondii dihydrofolate reductase-thymidylate synthase (DHFR-TS), eosin B offers a novel mechanism for inhibition of the parasitic folate biosynthesis pathway. In the present study, eosin B was further evaluated as a potential antiparasitic

    Automated image segmentation of haematoxylin and eosin stained skeletal muscle cross-sections
    (2013-12-01) F. Liu; A. L. Mackey; R. Srikuea; K. A. Esser; L. Yang; University of Kentucky; Bispebjerg Hospital; Kobenhavns Universitet; Mahidol University
    haematoxylin and eosin stained slides, is still a manual or semi-automatic process. This procedure is labour-intensive and time-consuming. In this paper, we have developed and validated an automatic image segmentation algorithm that is not only efficient... but also accurate. Our proposed automatic segmentation algorithm for haematoxylin and eosin stained skeletal muscle cross-sections consists of two major steps: (1) A learning-based seed detection method to find the geometric centres of the muscle fibres

    removal is unknown. The aim of this study was to investigate the toxicity of eosin dye and its removal by adsorbent. Moreover, the cytotoxicity of dye is evaluated by brine shrimp lethality bioassay. The results showed that the dye after removal... by eggshell had the lower mortality rate when compared to those of eosin dye and penut shell adsorption. The histopathological lesions such as abnormal appearance of enterocyte, blebing cell and coagulation necrosis were found. Therefore, these bio-natural

    the specificity of the designed YHV RNA specific primers. RT-PCR based detection demonstrated high sensitivity in that it could detect 0.01 pg of purified RNA. The results demonstrated a much more sensitive detection of YHV when compared to hematoxylin and eosin... probes for in situ DNA hybridization. For viral infected nuclei identified by hematoxylin and eosin staining in parallel samples, the 4.2 kb fragment gave a stronger DNA hybridization signal than did the 0.9 kb fragment. The 4.2 kb fragment was then used
