Intestinal trefoil factor (ITF), a small, compact protease-resistant peptide, is abundantly expressed in goblet cells of large and small intestine. Although several biological activities of ITF have been identified, including promotion of wound healing, stimulation of epithelial cell migration, and protection of intestinal epithelial barrier, little is known about signaling events through which...

Trefoil factor 1 (TFF1) belongs to a family of secreted peptides with a characteristic tree-looped trefoil structure. TFFs are mainly expressed in the gastrointestinal tract where they play a critical role in the function of the mucosal barrier. TFF1 has been suggested as a neuropeptide, but not much is known about its expression and function in the central nervous system. We investigated the e...

This is an expository account of a theorem of Louise Moser that describes the types of manifolds that can be constructed via Dehn surgery along a trefoil in the 3-sphere. These include lens spaces, connected sums of two lens spaces, and certain Seifert fibered spaces with three exceptional fibers. Various concepts from the topological theory of three dimensional manifolds are developed as needed.

The Kiepert trefoil is an algebraic curve with remarkable geometric and number theoretic properties. Ludwig Kiepert, generalizing ideas due to Serret Liouville, determined that it could be parametrized by arc length in terms of elliptic functions. In this note, we observe some other properties the curve. particular, a special example buckled ring, thus solitary wave solution planar filament equ...

Birdsfoot trefoil (Lotus corniculatus) is an underutilized forage legume in the Mountain West. It has several unique characteristics that make it worth considering, particularly for pasture. One of the key reasons to use birdsfoot trefoil is that it does not cause bloat when grazed as green, standing forage, even in pure stands. This is due to the presence of condensed tannins which bind with s...
