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.
By the end of this section, you will be able to:Describe physical and chemical immune barriersExplain immediate and induced innate immune responsesDiscuss natural killer cellsDescribe major histocompatibility class I moleculesSummarize how the proteins in a complement system function to destroy extracellular pathogens
Psychology is designed to meet scope and sequence requirements for the single-semester introduction to psychology course. The book offers a comprehensive treatment of core concepts, grounded in both classic studies and current and emerging research. The text also includes coverage of the DSM-5 in examinations of psychological disorders. Psychology incorporates discussions that reflect the diversity within the discipline, as well as the diversity of cultures and communities across the globe.Senior Contributing AuthorsRose M.

By the end of this section, you will be able to:Explain the nature of psychophysiological disordersDescribe the immune system and how stress impacts its functioningDescribe how stress and emotional factors can lead to the development and exacerbation of cardiovascular disorders, asthma, and tension headaches
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:
"The COVID-19 pandemic, caused by the virus SARS-CoV-2, has spread rapidly since 2019. COVID-19 symptoms are mild in some patients but severe and even life-threatening in others and there are still no reliable treatments for severe COVID-19. In a recent study, researchers investigated the factors related to COVID-19 severity in hospitalized patients with mild or severe illness. Specifically, they investigated the patients’ immune characteristics and signaling pathways involving immune proteins called IFN-Is. Compared with healthy controls, patients with COVID-19 had lower counts of many types of immune cells but higher counts of Th17 cells in their blood and the differences were more drastic in patients with severe disease. In addition, individuals with severe COVID-19 had much lower levels of IFN-I signaling molecules than healthy controls..."
