    摘要: A system and method for fluorescence spectral imaging of target material to detect the presence of a contaminant (such as aflatoxin in corn) is provided. An ultraviolet light source is coupled a light-excluding compartment. The fluorescence from the UV excited target passes through a filter (liquid crystal tunable, acoustic-optic tunable, a filter wheel, or other wavelength splitting device) and a lens, to a spectral imaging camera. Fluorescence spectral image data from the camera is analyzed by a computer and presented in human-readable form. Aflatoxin detection in contaminated corn kernels is based on peak fluorescence and peak fluorescence shift in the spectral range from 451 nm to 500 nm. Aflatoxin contamination level within the target material is quantified based on peak fluorescence and peak fluorescence shift and computed corn kernel pixel statistics.

    摘要: The flavonoid family of phytochemicals, particularly those derived from soy, has received attention regarding their hormonal activity and their effects on human health and disease. The types and amounts of these compounds in soy and other plants are controlled by both constitutive expression and stress-induced biosynthesis. The health benefits of soy may therefore be dependent upon the amounts of the various hormonally active phytochemicals present. We have identified increased biosynthesis of the isoflavonoid phytoalexin compounds, Glyceollins I, II and III, in soy plants grown under stressed conditions (elicited soy), which exhibit marked anti-estrogenic effects on ER function. Here we demonstrate that specific glyceollins, isolated from elicited soy, displayed anti-estrogenic activity, suppressing basal and estrogen stimulated colony formation of ER-positive estrogen dependent breast cancer cells and inhibiting ER-dependent gene expression of progesterone receptor (PgR) and stromal derived factor-1 (SDF1/CXCL12). Examining the effects of glyceollin on in vivo tumor formation/growth we demonstrate the ability of glyceollins to significantly suppress basal and estrogen-stimulated tumor growth of ER-positive MCF-7 breast and BG-1 ovarian carcinoma cells in ovariectomized female nude mice. We further demonstrate that the effects of glyceollins on suppression of tumor growth correlate with inhibition of estrogen stimulated PgR expression. In contrast to the uterotropic activity of tamoxifen the glyceollins displayed no uterine agonist activity. The Glyceollin (I-III) compounds may represent an important component of the health effects of soy as well as represent novel anti-estrogens useful in the prevention or treatment of breast and ovarian carcinoma.

    摘要: In a method and apparatus for identifying and distinguishing fungal species, a hyperspectral imaging scanner is used to acquire hyperspectral image data for radiation obtained from a sample area in which at least one unknown fungal species is present. A computer compares the acquired hyperspectral image data with spectral signature data stored in a digital library, which includes spectral signature data for each one of a group of known fungal species, and identifies the fungal species, based on the result of such comparison. The spectral signature data stored in the digital library take into account, for each fungal species, spectral variations that can occur due to at least one of environmental and temporal influences. The computer comparison includes a pixel-by-pixel analysis of the degree of difference between acquired hyperspectral image data and the spectral signature data, so that a spatial distribution of identified fungal species can be determined for a sample area.

    摘要: The present disclosure demonstrates the molecular effects of glyceollins on human prostate cancer cell LNCaP to further elucidate its potential effects on prostate cancer prevention. The glyceollins inhibited LNCaP cell growth similar to that of the soy isoflavone genistein. The growth inhibitory effects of the glyceollins appeared to be due to an inhibition on G1/S progression and correlated with an up-regulation of cyclin-dependent kinase inhibitor A1 and B1 mRNA and protein levels. By contrast, genistein only up-regulates cyclin-dependent kinase inhibitor A1. In addition, glyceollin treatments led to down-regulated mRNA levels for androgen responsive genes. In contrast to genistein, this effect of glyceollins on androgen responsive genes appeared to be mediated through modulation of an estrogen- but not androgen-mediated pathway. Hence, the glyceollins exerted multiple effects on LNCaP cells that may be considered cancer preventive and the mechanisms of action appeared to be different from other soy-derived phytochemicals.
