Evaluating a 12-week aerobic exercise intervention in adults with persisting post-concussive symptoms.

Background: Although guidelines support aerobic exercise in sub-acute mild traumatic brain injury (mTBI), evidence for adults with persisting post-concussive symptoms (PPCS) after mTBI is lacking. The objective was to evaluate the impact of a sub-symptom threshold aerobic exercise intervention on overall symptom burden and quality of life in adults with PPCS.

Methods: This prospective cohort study was nested within the ACTBI Trial (Aerobic Exercise for treatment of Chronic symptoms following mild Traumatic Brain Injury).

Investigating the Molybdenum Nitrogenase Mechanistic Cycle Using Spectroelectrochemistry.

Molybdenum nitrogenase plays a crucial role in the biological nitrogen cycle by catalyzing the reduction of dinitrogen (N) to ammonia (NH) under ambient conditions. However, the underlying mechanisms of nitrogenase catalysis, including electron and proton transfer dynamics, remain only partially understood. In this study, we covalently attached molybdenum nitrogenase (MoFe) to gold electrodes and utilized surface-enhanced infrared absorption spectroscopy (SEIRA) coupled with electrochemistry techniques to investigate its catalytic mechanism.

Service.

There are many dimensions to scientific life. We asked investigators about the impact of service to the scientific community and beyond and how service has shaped their experience, perspective, and research path.

Evolving Impact of COVID-19 on Intestinal Transplant Recipients: A Single-Center Experience.

Background: There has been significant concern about coronavirus disease 2019 (COVID-19) among transplant recipients, particularly those who are highly immunosuppressed. Several studies have analyzed the impact of COVID-19 on different solid organ transplant patients. However, few isolated case reports of COVID-19 in intestinal and multivisceral transplant (ITx and MVTx) recipients are available in the literature.

Don't Sleep on Sleep: A Case Report from a Division I Heptathlete.

A female NCAA Division I track athlete experienced non-localized shin pain midway through her first season, which was diagnosed as medial tibial stress syndrome. Treatments included strengthening and range of motion exercises, reduced training volume, and pain control modalities, but symptoms worsened. It was revealed she had been suffering from severe sleep deprivation (<3 hours/night) contributing to bilateral tibial and fibular stress reactions.
