Summer drought enhances diurnal amplitude of CO in two German rivers of different size.

Drought is becoming increasingly prevalent globally, stimulating research into its effects on river ecosystems. However, our understanding of how droughts affect riverine CO dynamics on a daily scale remains limited, particularly considering the likelihood of future drought occurrence. Here, we seize the opportunity to compare daily CO cycles between a non-drought summer and an unprecedented drought summer.

Establishing Indicative Neurofilament Gradients based on Severity of Spinal Cord Injury.

Introduction: Acute traumatic spinal cord injury (SCI) results in a lifelong condition without any standardized biomarker or corresponding interventions. The objective of this study was to correlate changes in fluid biomarkers with the severity of SCI.

Methods: The test model used forces of 100 and 200 kdyn.

Midseptal and Anteroseptal Accessory Pathway Ablation in Children.

The goal of this study is to document outcomes of ablation for high-risk accessory pathways in paediatrics using 3D mapping systems with minimal to zero fluoroscopy. It is a cross-sectional, multicentre study, conducted between 2013 and 2023, and involving four different centres in Hungary, Croatia, Kuwait, and Slovenia. A total of 128 procedures were performed on 111 patients.

Fast singlet excited-state deactivation pathway of flavin with a trimethoxyphenyl derivative.

Incorporation of the trimethoxyphenyl group at position 7 of flavin can drastically change the photophysical properties of flavin. We show unique fast singlet (π,π*) excited state deactivation pathway through nonadiabatic transition to the (n,π*) excited- state, and subsequent deactivation to the ground electronic state (S), closing the photocycle. This mechanism explains the exceptionally weak fluorescence and the short excited-state lifetime for the flavin trimethoxyphenyl derivative and the lack of excited triplet T state formation.

Arthrodesis as Salvage for Failed Metacarpophalangeal Arthroplasty.

Background: Surgical management of failed metacarpophalangeal (MCP) arthroplasties includes revision arthroplasty and arthrodesis. The purpose of this study was to review the indications and outcomes of arthrodesis as a salvage procedure for failed MCP arthroplasties.

Methods: This was a retrospective cohort study of all patients undergoing salvage MCP arthrodesis at a single institution from 1990 to 2020.
