Stable isotopes as a predictor for organic or conventional classification of berries and vegetables.

Organic agriculture is expanding worldwide, driven by expectations of improving food quality and soil health. However, while organic certification by regulatory bodies such as the United States Department of Agriculture and the European Union confirms compliance with organic standards that prohibit synthetic chemical inputs, there is limited oversight to verify that organic practices, such as the use of authentic organic fertilizer sources, are consistently applied at the field level. This study investigated the elemental content of carbon (C) and nitrogen (N) and their stable isotopes (δ13C and δ15N) in seven different crops grown under organic or conventional practices to assess their applicability as a screening tool to verify the authenticity of organic labeled produce.

Management of Concurrent Left Ventricular Pseudoaneurysm and Mitral Annular Calcification: A Case Report.

We describe the treatment of a 54-year-old man with a history of methicillin-resistant pericarditis who presented with left ventricular pseudoaneurysm following prior left anterior thoracotomy pericardial window. Surgical intervention included pseudoaneurysm repair using a wide patch. Additionally, an attempted mitral valve repair was converted to replacement due to intraoperative findings of significant calcification of the mitral anterior leaflet and annulus, along with suspected rheumatic changes.

Creating Time and Space for the Intersection of Climatological Disasters and Racial Inequalities Curricula in the Classroom.

Racial disparities and climatological disasters are complex topics rarely addressed in K-12 curricula. Each topic has long been neglected vis-à-vis a pedagogy that has either lagged behind contemporary issues or has intentionally sidestepped the importance of addressing these themes through legal and policy mechanisms that limit educators' ability to discuss each topic. When it comes to students and communities of color in the U.

Proposed Framework for Adopting Privacy-Preserving Record Linkage for Public Health Action.

Objectives: To propose a framework for adoption of privacy-preserving record linkage (PPRL) for public health applications.

Methods: Twelve interviews with subject matter experts (SMEs) were conducted virtually and coded using an inductive approach. A collaborative session was conducted with SMEs to identify key steps in the PPRL project lifecycle which informed development of a PPRL implementation checklist.
