When Seeing Is Believing: A Framework For Reflective Conversations In Remote And Face-To-Face Coaching Approaches, Cheryl Varghese, April Crawford, Linda Morgan-Dorsey, Maram Ahmed, Laura Prendergast, Tracy Osborn

Faculty, Staff and Student Publications

Reflective conversations between teachers and coaches are critical to helping teachers improve their classroom instruction. Coaches who encourage teachers to "see, think, and do" are better able to facilitate meaningful reflective conversations with teachers. The "See, Think, Do" framework consists of six steps (observe, describe, process, analyze, draw conclusions, and plan) that can be used to help coaches engage in reflective conversations with teachers. The framework can be readily implemented in remote and face-to-face coaching modalities and in one-on-one and small group delivery formats. Suggestions and strategies for implementing the framework in ongoing coach-teacher conversations are provided.

Faculty, Staff and Student Publications

Cutaneous radiation injury (CRI) interrupts the scheduled process of radiotherapy and even compromises the life quality of patients. However, the current clinical options for alleviating CRI are relatively limited. Resveratrol (RSV) has been shown to be a promising protective agent against CRI; yet the mechanisms of RSV enhancing radioresistance were not fully elucidated and limited its clinical application. In this study, we demonstrate RSV promotes cutaneous radioresistance mainly through SIRT7. During ionizing radiation (IR) treatment, RSV indirectly phosphorylates and activates SIRT7 through AMPK, which is critical for maintaining the genome stability of keratinocytes. Immunoprecipitation and mass spectrometry identified HMGB1 to …

Cone-beam CT provides an opportunity to image peripheral joints during weight-bearing, augmenting the …

Exaptation And Evolutionary Adaptation In Nociceptor Mechanisms Driving Persistent Pain, Edgar T Walters

Faculty, Staff and Student Publications

Background: Several evolutionary explanations have been proposed for why chronic pain is a major clinical problem. One is that some mechanisms important for driving chronic pain, while maladaptive for modern humans, were adaptive because they enhanced survival. Evidence is reviewed for persistent nociceptor hyperactivity (PNH), known to promote chronic pain in rodents and humans, being an evolutionarily adaptive response to significant bodily injury, and primitive molecular mechanisms related to cellular injury and stress being exapted (co-opted or repurposed) to drive PNH and consequent pain.

Summary: PNH in a snail (Aplysia californica), squid (Doryteuthis pealeii), fruit fly (Drosophila melanogaster), mice, rats, …

Oral Small Molecule Agents In Management Of Ulcerative Colitis: Fact Or Fancy?, Benan Kasapoğlu, Atilla Ertan

Faculty, Staff and Student Publications

Ulcerative colitis is a chronic, immune-mediated disease characterized by recurring episodes of mucosal inflammation in the colon and rectum. The primary pathogenic mechanism of ulcerative colitis is the dysregulation of the mucosal immune response. The disease follows a relapsing-remitting course, and the goal of management is to successfully induce and then maintain remission. Effectively managing this chronic disease requires addressing all aspects of it. Currently, we have various antitumor necrosis factor agents and novel biologics available for treating ulcerative colitis patients with moderate-to-severe disease. However, none of the existing treatments are considered entirely satisfactory or ideal in these cases. After …

Faculty, Staff and Student Publications

In equine ophthalmology, ulcerative keratitis is among the most common conditions and, in general, arises as a consequence of some trauma suffered. Secondarily, subsequent contamination by pathogenic or resident bacteria of the horse's ocular microbiota may have undesirable consequences. Under physiological conditions, the normal microbiota coexists with the immune status of the host, serving as a barrier, ensuring the health of the ocular surface, and inhibiting the proliferation of pathogens. However, in the imbalance of immune barriers, the normal microbiota can become pathogenic and lead to infection, acting as an opportunistic agent. The present study aims to demonstrate the antimicrobial …
