Article Abstract

On average less than half of the applied N is captured by crops, thus there is scope and need to improve N uptake in cereals. With nitrate (NO) being the main form of N available to cereal crops there has been a significant global research effort to understand plant NO uptake. Despite this, our knowledge of the NO uptake system is not sufficient to easily target ways to improve NO uptake. Based on this there is an identified need to better understand the NO uptake system and the signalling molecules that modulate it. With strong transcriptional control governing the NO uptake system, we also need new leads for modulating transcription of NO transporter genes.

Purpose: Cardiac noradrenergic denervation visualized by meta-[I]iodobenzylguanidine ([I]MIBG) imaging supports the diagnosis of Parkinson's disease (PD). Recently, meta-[F] fluorobenzylguanidine ([F]MFBG) PET demonstrated favorable imaging characteristics compared with [I]MIBG scintigraphy for neuroendocrine tumors. We assessed [F]MFBG dosimetry and myocardial pharmacokinetics in healthy controls and PD patients.

Microbes can be programmed to record participation in gene transfer by coding biological-recording devices into mobile DNA. Upon DNA uptake, these devices transcribe a catalytic RNA (cat-RNA) that binds to conserved sequences within ribosomal RNAs (rRNAs) and perform a trans-splicing reaction that adds a barcode to the rRNAs. Existing cat-RNA designs were generated to be broad-host range, providing no control over the organisms that were barcoded.

Chronic obstructive pulmonary disease (COPD) is a prevalent respiratory condition associated with increased morbidity and mortality, particularly during respiratory infections such as influenza. The interaction between COPD and influenza is multifaceted, involving compromised immune responses, chronic inflammation, and impaired lung function. Influenza infection can exacerbate COPD, leading to acute exacerbations, hospitalizations, and higher mortality.

The magnetic field is a continuously present environmental factor. It has been found that many species, including plants, can sense and utilise it. However, the effects of the magnetic field on plants and its potential utilisation, especially in crops, have been little explored.

Background: Conventional top-down health interventions often exclude adolescents and community stakeholders from service design and implementation, resulting in low uptake and a mismatch with young people's needs. The CAFFP-PAC initiative in Northern Uganda sought to explore how a community-led, adolescent-centered inception process could support integration of adolescent-friendly family planning and post-abortion care into primary healthcare services.

Methods: A participatory qualitative design was employed during an inception meeting in Lira City on April 1, 2025, guided by principles of community-based participatory research and citizen science.
