My Dog is Broken!: A Case Study in Cell Signaling

My Dog is Broken!: A Case Study in Cell Signaling

Cell signaling is one of the more difficult concepts for students to ... (more)

Cell signaling is one of the more difficult concepts for students to understand in their study of cell biology. To help students better understand the process of cell signaling, from reception to cellular response, a fairly simple signal pathway is used as an example in this case study in which students read a series of instant messages and emails between two friends trying to determine what is causing erectile dysfunction in a prize winning dog. The case was developed for use in an introductory biology course, but could also be used in a cell biology course. (less)

This case study follows a family's dilemma about how to save money on gasoline. Should they keep their SUV and trade in their Corolla for a hybrid sedan? Going from 28 (Corolla) to 48 (Hybrid) miles per gallon (MPG) should really save money on gas. That's a change of 20 MPG! Or, should they keep their Corolla and trade in their SUV for a minivan? The SUV gets about 13 MPG while the Minivan gets 17 MPG. Students learn how to analyze fuel efficiency in terms of "gallons per miles" driven instead of miles per gallon, and gain graphing and data analysis skills. An extension activity also relates fuel efficiency to greenhouse gas emissions. The case was developed for use in a high school general science course. It could be adapted for use in introductory physics, chemistry, algebra, or environmental science courses at the high school or college level. (less)

Focusing on the important role of water in living cellular chemistry, this ... (more)

Focusing on the important role of water in living cellular chemistry, this case emphasizes the general solubility rule, "like dissolves like," which explains how water can serve as a medium for transporting the cell's soluble nutrients and wastes. The case covers how the different interactions between water and glycerophospholipids' polar heads and non-polar tails direct the formation of the cell's membrane bilayer, and teaches students that water is instrumental in positioning amino acids according to their polarities during protein folding. Also reviewed are the chemical reactions of water during photosynthesis, respiration, dehydration, and hydrolysis. The case has been used with nursing students in the second semester of a General, Biological, and Organic Chemistry course. It can also be used as a review of basic biology and chemistry for upper level students in biochemistry. (less)

This case is based on the real-life incident of a boy whose arm was bitten off by a bull shark while swimming off the coast of Florida in the summer of 2001. After the boy's arm was retrieved from the shark's mouth, it was surgically reattached. The case was developed for use in the laboratory section of a freshman- or sophomore-level introductory human anatomy course that takes a regional approach. Several similar clinical cases are used in conjunction with each anatomical region as it is dissected. This particular case study is used during the dissection lab on the upper extremity of the human body. (less)

These days it seems like everyone is counting carbs. About 24 million Americans report they have cut carbohydrates from their diet, and 44 million more say they may try a low-carb diet in the next two years. But what do people really know about carbohydrates? This directed case study, designed for use in a large enrollment introductory course, teaches students how to recognize carbohydrates in the foods they eat and to differentiate between different classes of carbohydrates. Students learn how the body utilizes carbohydrates and discuss whether or not eliminating them from their diet can be healthful. (less)

This case reviews concepts of monosaccharide, disaccharide, and polysaccharide and contrasts the structures of different pairs of carbohydrates as well as the structure of sorbitol, a sugar substitute. It also depicts stereo chemistry concepts such as chiral carbon, enantiomer, anomer, Fisher projection, Haworth structure, and glycosidic bonds. In addition, the story associates the similar symptoms related to the gastrointestinal bacteria fermentation of lactose and soluble fibers and compares the enzymes that are responsible for the breakdown of lactose, amylose and cellulose. Furthermore, the case explains the health benefits of consuming insoluble fibers to prevent situations like constipation, diverticulosis, and colon cancer. Finally, the case study highlights the pros (for example, lowering absorptions of fats and glucose to prevent heart disease and the spike of the blood sugar levels after meals) and the cons (such as causing bloating and flatulence) of soluble-fiber consumption.

This case study is designed to integrate important aspects of the nervous and muscular system portions of an anatomy and physiology course. Students follow the story of "Kathy," whose symptoms involve both sensory and motor components of the nervous system. The students must recognize the key factors of nerve transmission, examine where there could be interruption, and recognize how the interruption would affect body function. They also need to identify the role that the nervous system plays in muscular function. Through the case, students explore the relationship between both body systems, consider how one affects the other, and discover how function can be affected by external factors. (less)

Alvin's parents are worried about him. He has had a cough for almost a week, and he's wheezing a lot more than they think is normal for a child with a cold, which is what their family pediatrician says he has. When they take him to the ER, however, the pediatric pulmonologist on duty tells them their son is suffering from something much more serious than a cold. This case study was developed for second-year pharmacy students to help them tie together elements of cell physiology, osmosis and tonicity, and membrane transport processes. The questions, which focus on disease mechanisms, symptoms, and treatment options, could be modified for non-pharmacy students. (less)
