A substantial fraction of nitrogen (N) fertilizer applied in agricultural systems is not incorporated into crops and moves below the rooting zone as nitrate (NO ). Understanding mechanisms for soil N retention below the rooting zone and leaching to groundwater is essential for our ability to track the fate of added N. We used dual stable isotopes of nitrate ( N-NO and O-NO ) and water ( O-HO and H-HO) to understand the mechanisms driving nitrate leaching at three depths (0.

Article Synopsis
- Small GTPases are a large family of proteins that play essential roles in cell processes like migration and growth, making them important for cell signaling.
- A standardized method to control the activation of these proteins in living cells has been lacking, which this study addresses.
- The researchers developed a split-protein technique that allows for direct activation of various small GTPases using customizable inputs, creating a versatile system for studying these proteins in real-time.
Introduction: Effective trauma care requires the rapid management of injuries. Rural and remote areas face inequity in trauma care due to time, distance and resource constraints, and experience higher morbidity and mortality rates than urban settings. A training needs analysis (TNA) conducted with stakeholders across Queensland, Australia, revealed a lack of contextual, accessible and interprofessional trauma education for clinicians.

Despite the importance of these proteins in cell signaling, a standardized approach for controlling small GTPase activation within living cells is lacking. Herein, we report a split-protein-based approach to directly activate small GTPase signaling in living cells.

Methods: Twenty participants (B/AA n = 10, White n = 10) performed three separate experimental trials. In the first trial, participants performed two VLs in a resting condition.
