Accurately representing the relationships between nitrogen supply and photosynthesis is crucial for reliably predicting carbon-nitrogen cycle coupling in Earth System Models (ESMs). Most ESMs assume positive correlations amongst soil nitrogen supply, leaf nitrogen content, and photosynthetic capacity. However, leaf photosynthetic nitrogen demand may influence the leaf nitrogen response to soil nitrogen supply; thus, responses to nitrogen supply are expected to be the largest in environments where demand is the greatest.

However, the effect of time delays on successful reperfusion in late window stroke patients presenting 6-to-24 h from onset has not been investigated.
Materials And Methods: We pooled individual patient-level data from seven trials and registries for anterior circulation stroke patients treated with EVT between 6 and 24 h from onset.
Anthropogenic activities have led to increased stress on our marine and other aquatic environments. There is a pressing need to monitor, measure, understand and mitigate causes of these pressures. This paper presents a novel optical head for monitoring and measuring marine based optical phenomena.

The purpose of this study was to evaluate the dynamic position of the chest port and catheter tip, comparing a demographically matched cohort of female breast cancer patients with right- or left-sided chest ports. 142 female patients with breast cancer requiring chest port insertion for chemotherapy and imaging confirming catheter tip position initially with supine fluoroscopy and follow-up with erect chest radiography over a 5-year period were identified.

Stentrievers and aspiration catheters are valuable devices for the management of these complications. We present our experience with the use of these devices.
