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:

"Stroke is the second leading cause of death and the third leading cause of disability worldwide. Most strokes are classified as ischemic, meaning they involve blockage of blood supply. There are no effective treatments for ischemic stroke or its complications, but several types of cells naturally produce molecules that can help heal ischemic tissue. These molecules are packaged and released within sacs called exosomes that can deliver them to other cells, making exosomes promising targets for stroke therapy. For example, some exosomes can exert anti-inflammatory effects, promote blood vessel formation, and support the development of new neurons. Beneficial exosomes can also suppress cell death and regulate immune responses. Studies on rat and rabbit stroke models have supported the clinical potential of exosomes to promote healing after stroke and a few clinical trials in humans are currently underway..."

Students learn the function of the liver and how biomedical engineers can use liver regeneration to help people. Students test the effects of toxic chemicals on a beef liver by adding hydrogen peroxide to various liver and salt solutions. They observe, record and graph their results.

"Hematopoietic stem cells (HSCs) are immature cells that can develop into all types of blood cells, making them critical regulators of blood composition. However, during aging, HSCs undergo a process called senescence, in which their functionality starts to fade, leading to issues like reduced immune cell populations or leukemia. HSC senescence is influenced by various age-related factors, like accumulated DNA damage or epigenetic (non-DNA-altering) changes in gene expression, and it’s regulated by small RNA molecules known as microRNAs (miRNAs). For example, the miR-212/132 cluster binds to the FOXO3 gene to affect HSC life cycles, function, and survival and is upregulated with aging, while miR-125b, which can help HSCs resist stress and cell death, is downregulated in aging HSCs..."

These educational resources have been developed so that primary school teachers can introduce scientific concepts related to the field of Nanomedicine.The contents are a tool for teachers and are intended to be a guide for classroom work. These are contents designed to be adapted according to the needs and criteria of each teacher. They have been developed taking into account the spanish educational curriculum and can freely be adapted to other curricular programmes.This project has been promoted by the Spanish Nanomedicine Platform (Nanomed Spain). Nanomed Spain brings together the main Spanish stakeholders in research, industry and administration in the field of Nanomedicine, in order to promote a common strategy to accelerate the development and introduction of innovative, more effective and personalized therapies in the healthcare system. One of the aims of the platform is to raise awareness of the research and potential of nanomedicine in society by promoting educational projects such as this one.Different entities have participated in the development of this project:Funding: Ministry of Science and InnovationTechnical and didactic support: Institute of Bioengineering of CataloniaEducational advice and pilot test: Gayarre School, Barcelona's public school for infant and primary education within the framework of the Aliances Magnet project.Original content development: Eduscopi
