First-Year Medical Student Experiences Adjusting to the Immediate Aftermath of COVID-19.

Problem: The COVID-19 pandemic required rapid changes to medical curricula, forcing emergent transition to purely remote learning. At Idaho College of Osteopathic Medicine (ICOM), all in-person sessions were suspended on March 16, 2020. One course affected included the first-year, 4-week Respiratory System course which began on March 9.

An endocrinological update in toads: disparity between the cardiovascular effects of two angiotensin II analogs.

This study was undertaken to test the hypothesis that, in toads, the pressor effects of angiotensin II (ANG II) are partly due to the secondary effects of catecholamines. In Bufo marinus, blood pressure responses to bullfrog ([Val(5)]) ANG II administration were measured in animals pretreated (experimental group) and not pretreated (control group) with phentolamine, an alpha-adrenergic antagonist. At 1, 2, and 4 min following ANG II administration (50 ngkg(-1)), mean arterial pressure (MAP) of the experimental group was significantly less than in the control group (27.
