在从压榨间直到蔗汁澄清的蔗糖生产过程中,蔗汁中微生物活动是破坏蔗糖品质的一个重要因素。蔗糖损失和葡聚糖的形成通常与蔗汁中微生物引起的变质有关。多年来,这一直成为糖厂试图改善蔗糖品质时所面临的问题。本文以直接影响得糖率的微生物减少和相对纯度为指标,研究了不同杀菌方法在蔗汁中的效果。浓度为0.007%的S抑制剂显示了对某糖厂初压汁和混合汁中的微生物菌群的抗菌效应。在对照组中,12h后观察到4.8单位的纯度降低。加入S抑制剂后,只降低2个单位。且蔗汁的稳定性在3个样品中几乎完全一致。以S抑制剂处理的蔗汁保持深褐色和清新的气味,且pH与初始相比无显著变化,而未处理的蔗汁变浅褐色,产生很强的酒味,pH和纯度显著降低。这种稳定效应尚未被其他常用的糖用杀菌剂所报导。同样,本文证明了有可能通过使用S抑制剂来稳定混合汁。经S抑制剂处理后,游离的还原物质和多聚糖比不经处理的样品低6倍。这些结果表明,形成的葡聚糖以及随之形成的游离果糖减少。

Breast cancer is the number one cause of can- cer deaths among Hispanic women in the United States, and in mexico, it recently became the primary cause of cancer deaths. This malign- nancy represents a poorly understood and un- derstudied disease in Hispanic women. The ELLA Binational Breast Cancer Study was es- tablished in 2006 as a multi-center study to as- sess patterns of breast tumor markers, clinical characteristics, and their risk factors in women of mexican descent. We describe the design and implementation of the ELLA Study and provide a risk factor comparison between women in the U.S. and those in mexico based on a sample of 765 patients (364 in the U.S. and 401 in mexico). Compared to women in mexico, U.S. women had significantly (p mean live births) and breastfeeding rates (57.5% vs. 80.5%), higher use of oral contraceptives (60.7% vs. 50.1%) and hormone replacement therapy (23.3% vs. 7.6%), and higher family history of breast cancer (15.7% vs. 9.0%). Re- sults show that differences in breast cancer risk factor patterns exist between mexico and U.S. women. We provide lessons learned from the conduct of our study. Binational studies are an important step in understanding disease pat- terns and etiology for women in both countries.
