Assessing seepage sources of a tailings dump and fractionation of Mo and Zn isotopes.

Tracing the sources of each contaminant and its geochemical reactions requires a variety of geochemical tools. In this study, chemical compositions and isotopic ratios of O-H, Mo, and Zn were utilized to identify the sources and geochemical reactions of water, As, Mo, and Zn in the seepage from a mine tailings dump. The distinct chemical compositions observed between the seepage and monitoring well, along with the O-H isotopic ratios, suggested that the seepage originated from creek water rather than nearby groundwater, which was supported by a large seasonal variation of δMo in both the seepage and creek.

The impact of regular physical activity on vertebral fractures: Korean nationwide population-based cohort study.

Background: Vertebral fractures are a common medical issue. Physical activity helps improve bone health and manage the risk of fractures. However, much controversy exists about the association between physical activity and vertebral fractures.

Ultrasound evaluation of clinical mimics of deep vein thrombosis: essential insights for radiologists in interpretation.

Ultrasonography (US) is a sensitive and radiation-free technique for diagnosing deep vein thrombosis (DVT). Therefore, when DVT is clinically suspected but not detected on US, radiologists should consider a range of alternative differential diagnoses. This review article presents the imaging findings of clinical conditions that mimic DVT, which can be distinguished using a multimodal radiologic approach.

The structure and function of the ghrelin receptor coding for drug actions.

Drugs targeting the ghrelin receptor hold therapeutic potential in anorexia, obesity and diabetes. However, developing effective drugs is challenging. To tackle this common issue across a broad drug target, this study aims to understand how anamorelin, the only approved drug targeting the ghrelin receptor, operates compared to other synthetic drugs.

Clinical Confidence, Certification, and Connectedness: Impact of a Journal Club for Inpatient Psychiatry Faculty.

Introduction: Inpatient psychiatry faculty manage complex clinical, administrative, and legal issues amid increasing mental health service utilization rates, limiting time for (1) focusing on lifelong learning and (2) connecting. We examined the impact of a monthly journal club on inpatient psychiatry faculty's (1) confidence that their practice is evidence informed, (2) stress related to board recertification, and (3) sense of connectedness with peers.

Methods: We employed a primarily qualitative approach using semi-structured interviews and brief survey questions to elicit input from inpatient psychiatry faculty at an academic medical center on their experience participating in a monthly journal club, including perceived changes in one's practice of evidence-based medicine, recertification stress, and connectedness with peers.
