Department of Plant Breeding, Swedish University of Agricultural Sciences, Alnarp, Sweden.
Background: Fusarium head blight (FHB) is a major disease affecting cereal crops including wheat, barley, rye, oats and maize. Its predominant causal agent is the ascomycete fungus Fusarium graminearum, which infects the spikes and thereby reduces grain yield and quality. The frequency and severity of FHB epidemics has increased in recent years, threatening global food security.

BMC Public Health
January 2025
Department of Care Science, Faculty of Health and Society, Malmö University, Malmö, Sweden.
Background: Everyday challenges and stress negatively affect young people's mental health. Socioeconomic status (SES) is associated with different stressors and different stress-coping mechanisms. Many interventions target youth mental health, but few consider socioeconomic differences in the planning, implementation, or evaluation.

Acta Neurochir (Wien)
January 2025
Department of Medical Sciences, Neurosurgery, Uppsala University, Uppsala, Sweden.
Purpose: The follow-up routine for patients with idiopathic normal pressure hydrocephalus (iNPH) after shunt surgery differs across medical centers. Shunt surgery is not without risks, with complications emerging at various times after the procedure. The aim was to explore the timing and methods of detecting complications following ventriculoperitoneal shunt surgery for iNPH.

DTU Aqua, Section for Aquaculture, Technical University of Denmark, Hirtshals, Denmark.
The unintended microbiological production of hydrogen sulphide (HS) poses a significant challenge in engineered systems, including sewage treatment plants, landfills and aquaculture systems. Although sulphur-rich amino acids and other substrates conducive to non-sulphate-based HS production are frequently present, the capacity and potential of various microorganisms to perform sulphate-free HS production remain unclear. In this study, we identify the identity, activity and genomic characteristics of bacteria that degrade cysteine to produce HS in anaerobic enrichment bioreactors seeded with material from aquaculture systems.

Carbohydr Polym
March 2025
Department of Molecular Sciences, Swedish University of Agricultural Sciences, Almas Allé 5, Uppsala 75651, Sweden. Electronic address:
Chitin is the second most abundant biopolymer in nature after cellulose and is composed of N-acetylglucosamine (GlcNAc) connected via β(1 → 4)-glycosidic bonds. Despite its prominence in nature and diverse roles in pharmaceutical and food technological applications, there is still a need to develop methods to study structure and function of chitin and its corresponding oligomers. Efforts have been made to analyse chitin oligomers by NMR spectroscopy, but spectral overlap has prevented any differentiation between the interior residues.
