Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:
"Cardiovascular diseases are the number one cause of death globally. One key process central to disease development is dysfunction of the vascular endothelial barrier. Vascular endothelial cells normally maintain homeostasis by acting as a barrier, preventing the infiltration of circulating cells and proteins into tissues, but TNF-α-mediated breakdown of this barrier can cause vascular hyperpermeability, resulting in worsening disease. A new study examined a compound with the potential to protect against barrier dysfunction. S-1-propenylcysteine (S1PC) is a sulfur-containing constituent in aged garlic extract (AGE), a preparation with demonstrated anti-inflammatory and anti-atherosclerotic effects. Using TNF-α-stimulated human cell lines, researchers evaluated endothelial permeability, protein localization, and GTPase activity following treatment with AGE and S1PC. They found that AGE and S1PC reduced hyperpermeability caused by TNF-α..."
