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.

Drug research has contributed more to the progress of medicine during the past century than any other scientific factor. With lecture snippets of Gerhard Domagk, Gertrude Elion and Brian Kobilka this Mini Lectures introduces to the fundamental research methods of drug targeting.

This course examines the growing importance of medicine in culture, economics and politics. It uses an historical approach to examine the changing patterns of disease, the causes of morbidity and mortality, the evolution of medical theory and practice, the development of hospitals and the medical profession, the rise of the biomedical research industry, and the ethics of health care in America.

Students demonstrate the erythrocyte sedimentation rate test (ESR test) using a blood model composed of tomato juice, petroleum jelly and olive oil. They simulate different disease conditions, including rheumatoid arthritis, anemia, leukocytosis and sickle-cell anemia, by making appropriate variations in the particle as well as in the fluid matrix. Students measure the ESR for each sample blood model, correlate the ESR values with disease conditions and confirm that diseases alter blood composition and properties. During the activity, students learn that when non-coagulated blood is let to stand in a tube, the red blood cells separate and fall to the bottom of the tube, resulting in a sediment and a clear liquid called serum. The height in millimeters of the clear liquid on top of the sediment in a time period of one hour is taken as the sedimentation rate. If a disease is present, this ESR value deviates from the normal, disease-free value. Different diseases cause different ESR values because blood composition and properties, such as density and viscosity, are altered differently by different diseases. Thus, the ESR test serves as a real-world diagnostic screening test to identify indications of the presence of any diseases in people.

"Our biological clock regulates everything from our body temperature to our eating habits. So much so that anything that throws it off beat could allow diseases to set in, including osteoarthritis. Muscle, bone, cartilage, and the tissue in between are reported to have regular rhythms that maintain joint health, and studies suggest that disturbances in the genes that regulate these rhythms could make symptoms of osteoarthritis worse. These disturbances affect the cells responsible for creating cartilage, increasing their breakdown while slowing their buildup. They lead to abnormal remodeling of bone tissue. They cause muscle fibers to age faster and become weaker. And they lead to inflammation in surrounding tissue, which aggravates joint pain and damage. Research that examines the relationship between rhythmic disturbances and osteoarthritis could lead to new ways of understanding joint degeneration and could inspire the development of new drugs that target the mechanisms underlying osteoarthritis..."

This multidisciplinary seminar addresses fundamental issues in global health faced by community-based healthcare programs in developing countries. Students will broadly explore topics with expert lecturers and guided readings. Topics will be further illuminated with case studies from healthcare programs in urban centers of Zambia. Multidisciplinary teams will be formed to develop feasible solutions to specific health challenges posed in the case studies and encouraged to pursue their ideas beyond the seminar. Possible global health topics include community-based AIDS/HIV management, maternity care, health diagnostics, and information technology in patient management and tracking. Students from Medicine, Public Health, Engineering, Management, and Social Sciences are encouraged to enroll. No specific background experience is expected, but students should have some relevant skills or experiences.

"Microbiome changes are linked to health in many animals, but the exact mechanisms are not known particularly in non-model organisms, like ostriches. Farmed ostriches have high neonatal mortality, primarily driven by gastrointestinal disease. A new study explored the possible role of microbiome patterns in growing captive ostriches. To do this, researchers examined the gut flora of several intestinal regions and sampled environmental bacteria. Individuals that succumbed to gastroenteritis had dramatically lower microbial diversity than age-matched controls, particularly in the ileum. The cecal and colon microbiomes of healthy individuals were similar to each other across hosts and ages, but diseased individuals had major disruptions. There was no evidence the taxa associated with mortality infiltrated from the environment at the onset of disease. Instead, they were present in the gut shortly after hatching and proliferated in individuals with low microbial diversity..."

DNA is the key to human life. When DNA is corrupted, changes occur in specific parts of the organism. Some of these changes can be fatal while others are beneficial. In this lesson we will look at the process of DNA mutation and how it impacts proteins produced by the organism.  You will research different genetic disorders and empathize with the impacts they have on your body.StandardsBIO.B.2.1 Compare Mendelian and non-Mendelian patterns of inheritance.

In this lesson, students will view a "yuck steak" and identify that the lesion is caused by an injection.  Students will then watch videos on how to administer an intramuscular and subcutaneous injection.  After watching the videos, the student will use the Marcel Marceau e-Moment to mime the procedures.  The students will then practice injections on an orange and cut the orange in half, viewing how the injections disperse throughout the orange.  The students will then video their demonstrations of each injection to submit for grading.NE.AFNR.HS.28.5.b or NE.AFNR.HS.29.5.b

"A plant’s microbiome is made up of all the microorganisms living on or in its tissues and can drive numerous aspects of its health and development. Scientists think it could be possible to harness these microbial communities to maximize crop health and productivity. To explore this possibility, a team of researchers examined the effects of glutamic acid, an important amino acid naturally produced by plants, on their microbiomes. Applying glutamic acid at 2-week intervals drastically altered the microbiome composition of strawberry and tomato plants, notably increasing the abundance of _Streptomyces globisporus_ SP6C4, a key microbe known to negatively affect pathogens that attack these species. This increase in _Streptomyces globisporus_ SP6C4 was also associated with reductions in diseases of both the leaves and roots, including gray mold and Fusarium wilt..."

"The next time you swat away that fly buzzing around your head, consider this: an international team of researchers has shown that common houseflies and blowflies are more than just annoying insects. Covered with hundreds of different bacterial species, they’re also a type of airborne delivery service, transporting pathogens from organic decaying matter right to your countertops, food…and body. Although flies have been long known to spread disease, the researchers show that we’ve previously underestimated both the number and diversity of microbes that each insect can transmit. The team devised a new optimized way to collect flies without cross-contaminating them with other microorganisms and used the method to amass 116 flies from urban, rural, and natural sites on three continents..."
