Principles of Biomedical Sciences - Course overview

Principles of Biomedical Sciences Course Overview

The Principles of Biomedical Sciences (PBS) course is divided into eight units designed to introduce students to the study of the human body and human medicine. The following is a description of each unit in the PBS course.
Unit 1 – Human Body Systems
Unit one introduces students to six major human body systems. Students explore the meaning of the term system, relate principles of engineering to systems, and investigate the interrelatedness of human body systems. Students begin to develop effective skills in conducting internet research, documenting scientific sources, and summarizing key ideas.
Unit 2 – Heart Disease
During unit two, students focus on the circulatory system. Students look at the role of this system in maintaining homeostasis by examining the structure and function of the heart and the engineering principles of fluid mechanics involved in pumping blood efficiently. Students are introduced to experimental design and LabVIEW software to collect and analyze heart data including: heart rate, blood pressure, and EKG.
Unit 3 – Diabetes
In this unit students investigate the serious effects a disease within one system can have on homeostasis in the body as a whole. The disease studied is diabetes. Students are introduced to basic chemistry, the biochemistry of macromolecules, and the relationship of these molecules to metabolic function. The causes, symptoms, treatments and effects of diabetes are studied as well as the life style implications associated with this disease. The engineering principles involved in feedback loops are discussed and related to insulin and glucose. Students are introduced to grant writing as they investigate future treatments currently being researched for diabetes.
Unit 4 – Sickle Cell Disease
Genetics is the focus of this unit which uses Sickle Cell Disease as a tool to gain an understanding of the inheritance of traits. Students are introduced to bio-informatics as they explore the role of genes in determining the structure and function of proteins. Students build models of DNA and the beta-globin protein as they study the structure, function, and interrelatedness of nucleic acids and proteins. To study the impact of mutations they analyze karyotypes and explore the effects of single base-pair mutations.
Unit 5 – Hypercholesterolemia
In unit 5, students look at the function of cholesterol in the body and its role in heart disease. DNA technologies including Polymerase Chain Reaction, Restriction Fragment Length Polymorphism analysis, and DNA electrophoresis are introduced as students complete activities dealing with the familial hypercholesterolemia gene.
Unit 6 – Infectious Diseases
Bacteria and viruses as the causative agents of infectious diseases is the focus of unit six. Structural differences between these organisms are examined as students Gram stain bacteria and produce models of virus particles. The differences in treatment protocols for bacterial and viral diseases are investigated. Students produce a public health campaign to educate peers about the dangers and prevention of an infectious disease of their choice.
Unit 7 – Medical Interventions
Medical interventions past and present are explored in this unit including surgery, medication, technology, and life style choice. The focus of the work is how medical interventions have changed over time to prolong and improve the quality of life. Students explore how a new pharmaceutical treatment goes from initial discovery to market, and research medical interventions currently available for common diseases or disorders including heart disease, sickle cell disease, hypercholesterolemia, and infectious diseases.
Unit 8 – Grant Proposal
Funding medical research through the grant writing process is the focus of unit eight. In teams, students prepare a written grant proposal and give an oral presentation supporting the proposal, based on a disease topic of their choice. The grant proposal is based on a National Institutes of Health grant structure. This is an in-depth research project completed over a lengthy period of time. The final proposal is presented to a Grant Evaluation Committee consisting of community members employed in medical, healthcare, education

Principles of Biomedical Sciences - Course description

This course provides an introduction to the biomedical sciences through exciting “hands-on” projects and problems. Student work involves the study of human medicine, research processes and an introduction to bio-informatics. Students investigate the human body systems and various health conditions including heart disease, diabetes, sickle-cell disease, hypercholesterolemia, and infectious diseases. A theme through the course is to determine the factors that led to the death of a fictional person. After determining the factors responsible for the death, the students investigate lifestyle choices and medical treatments that might have prolonged the person’s life. Key biological concepts including: homeostasis, metabolism, inheritance of traits, feedback systems, and defense against disease are embedded in the curriculum. Engineering principles including: the design process, feedback loops, fluid dynamics, and the relationship of structure to function are incorporated in the curriculum where appropriate. The course is designed to provide an overview of all the courses in the Biomedical Sciences program and to lay the scientific foundation necessary for student success in the subsequent
