Epithelial-mesenchymal transition (EMT) describes a series of rapid changes in cellular
phenotype. During EMT, epithelial cells down-modulate cell-cell adhesion structures, alter their …

The introduction of the Force Concept Inventory (FCI) by David Hestenes and colleagues in
1992 produced a remarkable impact within the community of physics teachers. An …

We have developed a whole-mount immunocytochemical method for Xenopus and used it
to map the expression of the intermediate filament protein vimentin during early …

Using a functional screen in Xenopus embryos, we identified a novel function for the HMG
box protein XSox17β. Ectopic expression of XSox17β ventralizes embryos by inhibiting the …

While researching student assumptions for the development of the Biology Concept Inventory
(BCI; http://bioliteracy.net ), we found that a wide class of student difficulties in molecular …

Publisher Summary This chapter discusses whole-mount staining of xenopus and other
vertebrates. Whole-mount staining makes the analysis of normal and experimentally …

Because Lewis structures provide a direct connection between molecular structure and
properties, the ability to construct and use them is an integral component of many chemistry …

A commonly accepted model of Wnt/β-catenin signaling involves target gene activation by a
complex of β-catenin with a T-cell factor (TCF) family member. TCF3 is a transcriptional …

A simple touch between organisms can convey a wide range of different messages, from
affection to hostility. Touch appears critical for both social intercourse and the achievement of …

Previously, we found that: (i) many students were unable to construct representations of
simple molecular structures; (ii) a majority of students fail to make the important connection …
