Genetic Testing for Common Cancer Genes.

Recent advances in the field of genetics have resulted in the ability to perform genetic tests on individuals to estimate their risk of developing certain diseases. This predictive testing can be used to determine the presence or absence of a specific genetic factor for types of breast, ovarian, colorectal, stomach, and ocular cancers. This article will discuss genetic testing for the cancers listed, including issues surrounding positive results; common issues that arise surrounding genetic testing; what to do when given the results; and what are the available preventative measures.

Ultrafiltration of thin stillage from conventional and e-mill dry grind processes.

We used ultrafiltration (UF) to evaluate membrane filtration characteristics of thin stillage and determine solids and nutrient compositions of filtered streams. To obtain thin stillage, corn was fermented using laboratory methods. UF experiments were conducted in batch mode under constant temperature and flow rate conditions.

Heat transfer fouling characteristics of microfiltered thin stillage from the dry grind process.

We investigated effects of microfiltration (MF) on heat transfer fouling tendencies of thin stillage. A stainless steel MF membrane (0.1 micron pore size) was used to remove solids from thin stillage.

Nutrient recovery from the dry grind process using sequential micro and ultrafiltration of thin stillage.

The effectiveness of microfiltration (MF) and ultrafiltration (UF) for nutrient recovery from a thin stillage stream was determined. When a stainless steel MF membrane (0.1microm pore size) was used, the content of solids increased from 7.

Thin stillage fractionation using ultrafiltration: resistance in series model.

The corn based dry grind process is the most widely used method in the US for fuel ethanol production. Fermentation of corn to ethanol produces whole stillage after ethanol is removed by distillation. It is centrifuged to separate thin stillage from wet grains.
