The role of the plasminogen activator system in the etiology of ovarian follicular cysts in dairy cattle

Creator:: McNeel, Anthony Kent
Abstract:: Cystic ovarian disease (COD) is an anovulatory condition in cattle that afflicts between 6-18% of all dairy cows in the US. Ovulation is dependent on the plasminogen activator (PA) family of proteases and protease inhibitor for proteolysis, culminating in follicular rupture. Failure of the follicle to ovulate suggests an aberration...

Inclusion of the variability of model parameters on shelf-life estimations for low and intermediate moisture vegetables

Creator:: Escobedo-Avellaneda, Zamantha, Velazquez, Gonzalo, Torres, J. Antonio, and Welti-Chanes, Jorge
Abstract:: Shelf-life is the time period during which products retain market-acceptable quality while meeting legal and safety requirements. Deterministic models yield single value estimations of shelf-life typically based on average or worst-case values for input parameters. In deterministic calculations, considering the input parameter variability can be challenging. In this study, a...

Effect of pressure-assisted thermal sterilization on conjugated linoleic acid (CLA) content in CLA-enriched milk

Creator:: Martinez-Monteagudo, Sergio I., Saldana, Marleny D. A., Torres, J. Antonio, and Kennelly, John J.
Abstract:: Conjugated linoleic acid (CLA) has been recently studied for its health-promoting and disease-preventing properties. The objective of this study was to evaluate the effect of pressure (100-600 MPa), temperature (60-120˚C) and treatment time (0-14 min) on CLA content in milk and anhydrous milk fat (AMF) rich in CLA. In milk...
