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.

"Glioblastoma is a highly malignant and frequently occurring tumor of the central nervous system. Recurrences are extremely common and often resist chemotherapy and radiotherapy, so new treatment options are needed. Immune checkpoint inhibitor immunotherapies successful in treating other types of cancer have been tried, but glioblastoma has resisted them. An effective therapeutic strategy must account for 3 things: glioblastoma's ability to evade immune system surveillance; its location behind the blood-brain barrier, which generally shields it from chemical compounds; and its inherent resistance due to its mutations and the variety of cells it contains. A tumor vaccination approach, which targets innate features of glioblastoma cells, has shown some promise. Vaccines based on peptides, cells, DNA, and mRNA have been developed. Unfortunately, few trials have reached phase III, because most patients with recurrent glioblastoma are very ill..."

Using a website simulation tool, students build on their understanding of random processes on networks to interact with the graph of a social network of individuals and simulate the spread of a disease. They decide which two individuals on the network are the best to vaccinate in an attempt to minimize the number of people infected and "curb the epidemic." Since the results are random, they run multiple simulations and compute the average number of infected individuals before analyzing the results and assessing the effectiveness of their vaccination strategies.

D-Lab Health provides a multidisciplinary approach to global health technology design via guest lectures and a major project based on fieldwork. We will explore the current state of global health challenges and learn how to design medical technologies that address those problems. Students may travel to Nicaragua during spring break to work with health professionals, using medical technology design kits to gain field experience for their device challenge. As a final class deliverable, you will create a product design solution to address challenges observed in the field. The resulting designs are prototyped in the summer for continued evaluation and testing.

"Exosomes are small membrane-bound vesicles that facilitate cell-to-cell communication by transporting biomolecules like proteins, RNA, and lipids. Due to their ubiquity and cargo-carrying abilities, exosomes have many potential uses in clinical medicine. First, they can be found in many biofluids like blood, urine, cerebrospinal fluid, saliva, and milk. This means they’re easy to collect and could be used in diagnostic testing as biomarkers. Beyond that, exosomes can be used to deliver cargo to key cells, either using naturally occurring exosomes or fashioning them into drug delivery vehicles. There are even promising results for exosome-based vaccines, not only for infectious diseases but anti-tumor vaccines as well. While the field has developed rapidly in recent decades, there is much more work to do. Specifically, researchers still need to elucidate the mechanisms of exosome transfer within the body..."

This lesson describes the major components and functions of the immune system and the role of engineers in keeping the body healthy (e.g., vaccinations and antibiotics, among other things). This lesson also discusses how an astronaut's immune system is suppressed during spaceflight due to stress and other environmental factors.

In this lesson, students will watch a video/teacher demonstration on how to properly fill a syringe.  The students will mime the procedure while the teacher reviews the procedures.  Students will also practice with a syringe, needle, and sterile water bottle.  Once the students are comfortable with the procedures, they will make a recording of their demonstration to be submitted for grading.NE.AFNR.HS.28.5.b or NE.AFNR.HS.29.5.b

The course covers basic concepts of biomedical engineering and their connection with the spectrum of human activity. It serves as an introduction to the fundamental science and engineering on which biomedical engineering is based. Case studies of drugs and medical products illustrate the product development-product testing cycle, patent protection, and FDA approval. It is designed for science and non-science majors.

"Livestock health is critical to food security, and parasite infections are a major threat. Gastrointestinal helminths have a huge impact on health and welfare of livestock and on food production worldwide. Resistance to parasiticides has become widespread, making the control of these infections highly challenging. Control strategies thus far have targeted either the parasite or the host’s immune response, but a third party may hold the key to addressing this issue. Microbes residing within the livestock gut are likely to contribute to the immunopathology of helminth infections. A recent study examined the relationships between gastrointestinal helminths, the host immune system, and the gut microbiota. Using DNA sequencing and confocal microscopy, researchers assessed fluctuations in the microbiota and local immune responses of vaccinated and unvaccinated helminth-infected sheep. Their results showed that gut microbial composition changed significantly during parasite infection..."

"A new vaccine against influenza virus may offer previously unattainable levels of protection to newborn pigs. Just as humans muddle through the flu season each year, pigs across the globe are affected by their own regular outbreaks, causing notable economic losses in the pork industry. But an international research team has now shown that the newly developed vaccine can keep the virus from replicating in newborn pigs, potentially reducing the spread of disease. Historically, breeding females have been the main target for influenza control in pig populations. Females given a vaccine containing an inactive form of influenza type A virus – a key agent of respiratory disease in pigs – can confer passive immunity to their offspring. But this doesn’t stop piglets from becoming infected with or passing on the virus – it just keeps them from showing clinical signs for a short period, since any maternally derived protection will wear off over time..."

A decade ago, the possibility of a link between the MMR vaccine and autism hit the media. Fear of the vaccine spread rapidly and, despite an almost unanimous consensus that the claim was unfounded, still persists today. In this unit, we'll examine why this controversy took on such a life of its own and why parents still agonise about the vaccine.

This collection uses primary sources to explore the polio epidemic and vaccine. Digital Public Library of America Primary Source Sets are designed to help students develop their critical thinking skills and draw diverse material from libraries, archives, and museums across the United States. Each set includes an overview, ten to fifteen primary sources, links to related resources, and a teaching guide. These sets were created and reviewed by the teachers on the DPLA's Education Advisory Committee.
