BACKGROUND Milk products deviate from other carbohydrate-containing foods in that they produce high insulin responses, despite… (More)

Here, x is the intracellular TMG concentration, y is the concentration of LacY in green fluorescence units, RT is the total… (More)

Membrane transport proteins that transduce free energy stored in electrochemical ion gradients into a concentration gradient are… (More)

A mathematical model for the regulation of induction in the lac operon in Escherichia coli is presented. This model takes into… (More)

We describe a bacterial two-hybrid system that allows an easy in vivo screening and selection of functional interactions between… (More)

Constipation is an ailment encountered often in elderly people. A study was initiated to test the effects of lactose or inulin on… (More)

The use of gel electrophoresis for quantitative studies of DNA-protein interactions is described. This rapid and simple technique… (More)
