Nitrogen (N) doping of biomass prior pyrolysis has been identified as an effective approach for enhancing biochar catalytic reactivity. However, high-temperature pyrolysis of N-rich biomass may produce N-devoid biochars with high reactivity, calling for attention to the true causes of the reactivity increases and the role of nitrogen. In this study, N-doped wheat straw biochar (N-BC) materials were produced using urea as N dopant and different pyrolysis conditions, and their catalytic reactivity assessed for the reduction of trichloroethylene (TCE) by green rust (GR), a layered Fe(II)Fe(III) hydroxide.

Our study examines genetically predicted variability in blood cell indices in relation to glioma risk and survival in 3418 cases and 8156 controls. We find that increased platelet to lymphocyte ratio (PLR) confers an increased risk of glioma (odds ratio (OR) = 1.

The disease has neurovascular origin and migraine attacks can be elicited by vasodilative neuropeptides such as alpha calcitonin gene-related peptide (αCGRP). Antagonizing CGRP actions in migraine patients has proven clinically efficient.

Aims: To investigate the impact of a novel digital leakage notification system on worry related to stoma leakage, and to evaluate the effect on overall stoma care management.
Method: A 12-week interventional, single-arm, multicentre study was conducted in the UK to evaluate the novel digital leakage notification system, including a telemedicine-based support service (=test product), as part of routine stoma care in patients with a recent stoma formation (ClinicalTrials.
Introduction: Chronic obstructive pulmonary disease (COPD) costs EURO 1.4 billion annually in healthcare costs. Pulmonary rehabilitation (PR) is a vital aspect of care for patients with COPD, but despite the compelling evidence, it is delivered to less than 30%.
