Caught Red-Handed - National Center for Case Study Teaching in Science - 0 views

  •  
    Was the "Brooklyn Butcher" of 1926 a cold-blooded killer or was something less sinister at play? This interrupted case study introduces students to hemoglobin binding and carbon monoxide poisoning by working through the details of a fictionalized account of a true-crime story. Topics covered include molecule conformational states, binding affinity, deoxyhemoglobin, oxyhemoglobin, carboxyhemoglobin, and oxygen transport. Students also design an experiment to determine the cause of death of the victim. Prior to beginning the activity students should have some knowledge of the respiratory and circulatory systems and be familiar with oxygen binding curves. Detailed understanding of hemoglobin conformational changes is not necessary since this information is covered in the case. Students will also learn briefly about the electromagnetic spectrum and visible light. Originally developed for a non-majors, pre-nursing anatomy and physiology course, the case is also appropriate for use in any of the following courses: introductory biochemistry, introductory biology, introductory chemistry, nursing, exercise physiology, or possibly even introductory physics.

A Botched Botox Party in the Hamptons - National Center for Case Study Teaching in Science - 0 views

  •  
    This flipped case study explores how the topics of membrane structure, transport, and signaling via membrane-bound receptors are intimately associated with the paralysis of muscle targeted by botulinum neurotoxin. The case scenario revolves around a fictitious socialite that has requested the assistance of her personal concierge physician with a condition that has developed after having participated in a Hamptons Botox party. The physician and a shadowing pre-med undergraduate chat about the molecular mechanisms behind Botox induced muscle paralysis. The case is designed as an engaging capstone exercise for students to gain appreciation for how knowledge of basic cellular and molecular biology mechanisms are essential for pharmaceutical development and medical patient diagnosis and prognosis. Written for an undergraduate general biology course, the case is also suitable for use in courses such as cellular biology, neurobiology, or human physiology.

The Water in Weberville - National Center for Case Study Teaching in Science - 0 views

  •  
    This case study presents a realistic example of drinking water contamination within a fictional local community and leads students through an abbreviated human health risk assessment. Students are provided background information about the extent of the contamination and a description of the contaminated site and are then required to calculate both the cancer and non-cancer risks to the community. This exercise is appropriate for an environmental toxicology or environmental risk assessment course. It works well after a lecture on the basics of risk assessment including how to calculate exposure intakes and risk estimates.
