The Structure of Maltooctaose-Bound Branching Enzyme Suggests a Mechanism for Donor Chain Specificity.

Glycogen is the primary storage polysaccharide in bacteria and animals. It is a glucose polymer linked by α-1,4 glucose linkages and branched via α-1,6-linkages, with the latter reaction catalyzed by branching enzymes. Both the length and dispensation of these branches are critical in defining the structure, density, and relative bioavailability of the storage polysaccharide.

Reveal Q+ MAX for Detection of Total Af latoxin in Corn, Almonds, Pistachios, Walnuts, and Peanuts.

The Reveal Q+ MAX for Aflatoxin is a lateral flow immunochromatographic test intended for quantitative analysis within 6 min after aqueous extraction. Work was conducted to validate the performance of the Reveal Q+ MAX for Aflatoxin method in selected corn and nut matrixes. This method was validated under the requirements of the AOAC Research Institute program.

Crystal Structures of Escherichia coli Branching Enzyme in Complex with Linear Oligosaccharides.

Branching enzyme is responsible for all branching of glycogen and starch. It is an unusual member of the α-amylase family because it has both α-1,4-amylase activity and α-1,6-transferase activity [Drummond, G. S.

Improvements in self-administration studies based on changes in skin button type and surgical technique.

Introduction: These studies, ranging in duration from 3 to 8months, evaluated the patency and longevity of the intravenous (IV) self-administration surgical model in male Sprague Dawley rats. Surgeries were categorized and assessed based on the number of catheter and/or skin button repairs required per animal across four separate self-administration studies. Design improvements in skin button types and changes in surgical procedures were chronologically tracked and assessed.

A behavioral economic analysis of the effect of next-day responsibilities on drinking.

Approximately 37% of college students report heavy episodic drinking (5 or more drinks in an occasion for men and 4 or more for women) in the past month. This pattern of drinking is often associated with high blood alcohol levels, accidents, injuries, and negative social and academic outcomes. There is a need for novel theoretical approaches to guide prevention efforts.
