"A new report published in Arthritis & Rheumatology suggests that cardiovascular disease affects patients with systemic lupus erythematosus much earlier than previously thought – in some cases even before active lupus sets in. The finding was reported by a team of researchers based in China who have been working on validating the use of magnetic resonance imaging to detect the early manifestations of cardiac impairment. With heart disease being the leading cause of death in patients with SLE, the ability to detect very early signs of cardiac dysfunction in this group could one day lay a foundation for enhanced preventive strategies. Traditional cardiac MRI approaches like late gadolinium enhancement don’t perform well in detecting early indications of heart disease, such as disturbances in myocardial extracellular volume. Missing these early warning signs could hide the fact that heart disease has set in and potentially complicate treatment efforts..."

This team-taught multidisciplinary course provides information relevant to the conduct and interpretation of human brain mapping studies. It begins with in-depth coverage of the physics of image formation, mechanisms of image contrast, and the physiological basis for image signals. Parenchymal and cerebrovascular neuroanatomy and application of sophisticated structural analysis algorithms for segmentation and registration of functional data are discussed. Additional topics include: fMRI experimental design including block design, event related and exploratory data analysis methods, and building and applying statistical models for fMRI data; and human subject issues including informed consent, institutional review board requirements and safety in the high field environment.

This lesson introduces the MRI Safety Grand Challenge question. Students are asked to write journal responses to the question and brainstorm what information they will need to answer the question. The ideas are shared with the class and recorded. Students then watch a video interview with a real life researcher to gain a professional perspective on MRI safety and brainstorm any additional ideas. The associated activity provides students the opportunity to visualize magnetic fields.

"One of the goals of ACL reconstruction surgery is to eliminate anterolateral rotational laxity of the knee. Biomechanical studies have shown that rotational control of the knee is largely controlled by the iliotibial band—specifically, the Kaplan fibers that anchor the band to the distal femur. Despite this critical connection, it remains unclear how often the iliotibial band and Kaplan fibers are compromised in association with ACL injury. To find out, researchers examined data for 267 patients with ACL-injured knees undergoing reconstruction surgery. They analyzed MRI scans to determine the extent of Kaplan fiber injury, and correlated those findings with the grade of pivot shift reported by the surgeon before the procedure. Only 47 patients, or approximately 18% of all patients, showed a Kaplan fiber injury. The majority of patients in the intact and injured Kaplan fiber groups had a grade-2 pivot shift. While only about 5% of all patients had a grade-3 pivot shift..."

Students are given an engineering challenge: A nearby hospital has just installed a new magnetic resonance imaging facility that has the capacity to make 3D images of the brain and other body parts by exposing patients to a strong magnetic field. The hospital wishes for its entire staff to have a clear understanding of the risks involved in working near a strong magnetic field and a basic understanding of why those risks occur. Your task is to develop a presentation or pamphlet explaining the risks, the physics behind those risks, and the safety precautions to be taken by all staff members. This 10-lesson/4-activity unit was designed to provide hands-on activities to teach end-of-year electricity and magnetism topics to a first-year accelerated or AP physics class. Students learn about and then apply the following science concepts to solve the challenge: magnetic force, magnetic moments and torque, the Biot-Savart law, Ampere's law and Faraday's law. This module is built around the Legacy Cycle, a format that incorporates findings from educational research on how people best learn.

"Can athletes’ ACLs be “trained” to resist injury? A new study published in The American Journal of Sports Medicine suggests that it’s possible. Studies on animals have shown that exercise during growth periods like puberty can “bulk up” the ACL, increasing its size and improving its mechanical properties. However, evidence of so-called “ACL hypertrophy” in human athletes is scarce. To address this gap, researchers examined the knees of 52 athletes who had been skating or diving since before puberty or since puberty onset. These types of athletes always land or jump up using the same leg, which the researchers labeled as the “dominant leg,” and thus habitually load one knee more than the other while training for their sport. Specifically, the team compared ACL and patellar tendon dimensions and knee strength between the left and right knees. They also examined how differences in ACL dimensions between knees correlated with age at training onset and with the number of years of training..."

Psychology is designed to meet scope and sequence requirements for the single-semester introduction to psychology course. The book offers a comprehensive treatment of core concepts, grounded in both classic studies and current and emerging research. The text also includes coverage of the DSM-5 in examinations of psychological disorders. Psychology incorporates discussions that reflect the diversity within the discipline, as well as the diversity of cultures and communities across the globe.Senior Contributing AuthorsRose M.
