A Qualitative Study of Physician Assistant Student Reflections in a Service-Learning Community Clinic and the Influence on Professional Identity Formation.

Introduction: Service learning is a commonly used teaching modality in physician assistant (PA) programs; however, the literature analyzing the written reflections of PA students who participate in these experiences is limited. The purpose of this study was to describe the experiences of PA students who participated in a service-learning clinic through analysis of their written reflections.

Methods: An exploratory qualitative research design, using conventional content analysis, was used to examine the reflections of both didactic and clinical-phase PA students who participated in a service-learning clinic between 2016 and 2020.

Aqueous extract of Spirulina exerts neuroprotection in an experimental model of Alzheimer sporadic disease in mice induced by Streptozotocin.

Alzheimer's disease (AD) is a progressive neurodegenerative disease that causes gradual memory loss and cognitive impairment. Intracerebroventricular injections of streptozotocin (ICV-STZ) have been used as an experimental model of sporadic Alzheimer's disease (SAD) because they produce deficits in brain insulin signaling, oxidative stress, neuroinflammation, and neurodegeneration, resulting in cognitive decline and memory impairment. Spirulina platensis (SPI) is a nutraceutical with anti-inflammatory, antioxidant, and neuroprotective properties.

Influence of ceramic crown design (translucent monolithic zirconia vs. bilayered) of implant-supported single crowns after mechanical cycling.

Objectives: This study aimed to assess the influence of translucent monolithic versus bilayered crowns and whether the use of a CoCr base abutments affects the fatigue and fracture resistance of screwed implant-supported single crowns with external connections under mechanical cycling.

Byrsonima sericea Ethanol Extract Protected PC12 Cells from the Oxidative Stress and Apoptosis Induced by 6-Hydroxydopamine.

Parkinson's disease is characterized by the progressive loss of dopaminergic neurons in the nigrostriatal pathway and oxidative stress is one of the main mechanisms that lead to neuronal death in this disease. Previous studies have shown antioxidant activity from the leaves of Byrsonima sericea, a plant of the Malpighiaceae family. This study aimed to evaluate the cytoprotective activity of the B.

Palmatine, a natural alkaloid, attenuates memory deficits and neuroinflammation in mice submitted to permanent focal cerebral ischemia.

Ischemic stroke is one of the major causes of human morbidity and mortality. The pathophysiology of ischemic stroke involves complex events, including oxidative stress and inflammation, that lead to neuronal loss and cognitive deficits. Palmatine (PAL) is a naturally occurring (Coptidis rhizome) isoquinoline alkaloid that belongs to the class of protoberberines and has a wide spectrum of pharmacological and biological effects.
