Hop derived bitter compounds, including alpha-acids, reduced and non-reduced iso-alpha-acids, were evaluated for their contribution to peak bitter intensity in lager beer. Alpha-acids are the precursors to the major bittering components in beer (iso-alpha-acids). Typically, alpha-acids do not survive the brewing process, but if a product is dry-hopped, they may...
Hop downy mildew is a devastating disease affecting hop requiring expensive
fungicide applications throughout the growing season. Plant resistance is highly
desirable and theorized as being decidedly quantitative with dominance and epistasis
involved in resistance. An association mapping approach using a mixed-model was
used to identify AFLP markers associated with...
Podosphaera macularis causes one of the most important diseases, powdery mildew, of Humulus lupulus (hop). If left unmanaged, hop powdery mildew can cause total crop loss due to disease or browning of hop cones rendering the cones unmarketable to buyers. The Hop Powdery Mildew Infection Risk Index (HOPS) is heavily...
This compilation of theses and dissertations (a part of the OSU Bibliographic Series) for the period 1970-1977 reflects this university's emphasis on research and graduate study. It may be viewed as an indicator of the contributions made to the state of Oregon through graduate study and research at Oregon State...
This thesis details my investigation of some pharmaceuticals and natural products on the transport of drugs which are substrates of P-glycoprotein (P-gp), such as cyclosporin A (CSA) and digoxin by using Caco-2 and MDCKII-MDR1 drug transport models. Three objectives were performed to address this goal. The first objective was to...
Alpha acids are found in the lupulin glands of hops cones. These acids have no bitterness of their own, but can be isomerized and subsequently hydrogenated to form bitter iso-α-acids and tetrahydroiso-α-acids respectively. Current literature values for the detection thresholds of iso-α-acid and tetrahydroiso-α-acid in lager beer have been reported...
