    Abstract: A polymerizable composition including a late transition metal complex, a non-polar olefin, a polar olefin, and a free radical scavenger, wherein the polymerizable composition is capable of forming a linear poly[(non-polar olefin)-(polar olefin)] substantially free of free radical addition polymer, is disclosed. A method of copolymerizing a non-polar olefin with a polar olefin, catalyzed by a late transition metal complex in the presence of a free radical scavenger, to produce a linear poly[(non-polar olefin)-(polar olefin)] substantially free of free radical addition polymer is also disclosed.

    Abstract: 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.

    Abstract translation: 植物化学成分的黄酮类化合物,特别是那些衍生自大豆的类黄酮,已经受到关于其激素活性及其对人类健康和疾病的影响的关注。 这些化合物在大豆和其他植物中的类型和数量都受到组成型表达和应激诱导的生物合成的控制。 因此,大豆的健康益处可能取决于存在的各种激素活性植物化学物质的量。 我们已经确定了在胁迫条件下生长的大豆植物(引发的大豆)中异黄酮类植物抗坏血酸化合物Glyceollins I,II和III的生物合成的增加,其对ER功能表现出显着的抗雌激素作用。 在这里我们证明,从引出的大豆中分离的特定的果糖显示出抗雌激素活性,抑制ER阳性雌激素依赖性乳腺癌细胞的基础和雌激素刺激的集落形成,并抑制孕激素受体(PgR)和基质衍生的ER依赖性基因表达 因子-1(SDF1 / CXCL12)。 检查血糖浓度对体内肿瘤形成/生长的影响,我们证明了血清蛋白在卵巢切除的雌性裸鼠中显着抑制ER阳性MCF-7乳腺和BG-1卵巢癌细胞的基础和雌激素刺激的肿瘤生长的能力。 我们进一步证明,糖蛋白对抑制肿瘤生长的影响与抑制雌激素刺激的PgR表达有关。 与他莫昔芬的子宫活动相反,glyceollins不显示子宫激动剂活性。 Glyceollin(I-III)化合物可能代表大豆健康影响的重要组成部分,也可代表用于预防或治疗乳腺癌和卵巢癌的新型抗雌激素。

    Abstract: A plate washing system and method of cleaning pipes of the plate washing system. The plate washing system includes at least one manifold having a plurality of pipes configured to be provided within wells of a plate in order to wash the wells, at least one manifold having a plurality of pipes, a tank, an ultrasonic transducer mounted to the tank, and a control system. When tips of the pipes are positioned within the tank, the control system activates the ultrasonic transducer in order to vibrate a fluid within the tank. An additional level sensing system which can detect fluid levels in order to establish instrument function and/or the need to clean via the ultrasonic cleaning system.
