Internal Medicine and Internal Medicine-Pediatrics Residency Program Website Traffic Patterns Across Two Institutions and Five Electronic Residency Application Service (ERAS) Cycles.

Background Since the start of the COVID-19 pandemic in Spring 2020, medical residency program recruitment has become increasingly web-based due to the transition to virtual interviews. Although social media use by residency programs has soared during this time, applicant surveys show that official program websites remain the most used online resource. According to survey-based studies, the content that applicants favor on program websites tends to mirror their priorities in choosing programs.

Modeling oxygen effects in tissue-preparation neuronal-current MRI.

Tissue-preparation neuronal-current MRI (ncMRI) was recently developed to directly detect neuronal activity without hemodynamic contamination. However, as a paramagnetic substance, the oxygen molecules present in the tissue may also alter the ncMRI signal through relaxivity and susceptibility effects. To study the effects of oxygen on the ncMRI signal and estimate their impact on tissue-preparation experiments, oxygen-induced MRI signal changes were formulated as a function of oxygen concentration (OC) of gas, oxygen consumption rate, and imaging parameters.
