Non-classical MHC class I genes which, compared to classical MHC class I, are typically less polymorphic and have more restricted expression patterns are attracting interest because of their potential to regulate immune responses to various pathogens. In salmonids, among the numerous non-classical MHC class I genes identified to date, L lineage genes, including Sasa- and , are differentially induced in response to microbial challenges. In the present study, we show that while transcription of both and are induced in response to SAV3 infection the transcriptional induction patterns are distinct for each gene.

Seagrass meadows are vital blue carbon habitats, with sedimentary organic carbon (OC) originating from both the seagrass itself and external sources. In this study, lipid biomarkers (n-alkanes), a well-known proxy for tracing OC sources, were used to indicate seagrass presence in sediment records and to correlate with sedimentary OC in cold-temperate seagrass (Zostera marina) sediments. We calculated a Zostera-ratio (seagrass/algae and terrestrial plants-ratio) using identified seagrass biomass n-alkanes (C, C, C, C, C) as a fingerprint for seagrass-derived OC.

Negotiating Normalcy: Epistemic Errors in Self-Diagnosing Late-ADHD.

Cult Med Psychiatry

January 2025

Roskilde University, Universitetsvej 1, 4000, Roskilde, Denmark.

In this paper, I share insights from ongoing ethnographic fieldwork among adult Danes who identify as having Attention Deficit Hyperactivity Disorder (ADHD) but do not meet the clinical standards and have yet to receive a diagnosis. These individuals are particularly relevant to the ongoing debates about under- and overdiagnosis of ADHD, as their claims to the diagnosis influence and mirror societal perceptions of what is considered normal and what is seen as a condition. Despite their symptoms not strictly meeting diagnostic criteria, thus risking overdiagnosis and associated psychiatric labeling, they perceive themselves as distinct from 'normal' people.

The choice of organism to host a genetic circuit, the chassis, is often defaulted to model organisms due to their amenability. The chassis-design space has therefore remained underexplored as an engineering variable. In this work, we explored the design space of a genetic toggle switch through variations in nine ribosome binding site compositions and three host contexts, creating 27 circuit variants.

Background: There is a lack of knowledge on effective treatment methods for comorbid benzodiazepine dependence in populations undergoing opioid agonist treatment (OAT). Tapering and discontinuation of benzodiazepines has long been considered the standard treatment, even though there is limited evidence for this practice. There is also limited research on benzodiazepine agonist treatment; however, peer and clinical experiences indicate that such approaches may be beneficial for a subgroup of the patients with long-lasting benzodiazepine dependence not responding to other treatment approaches.

Environmental Conditions Modulate Warming Effects on Plant Litter Decomposition Globally.

Ecol Lett

January 2025

Climate Impacts Research Centre, Department of Ecology and Environmental Sciences, Umeå University, Umeå, Sweden.

Empirical studies worldwide show that warming has variable effects on plant litter decomposition, leaving the overall impact of climate change on decomposition uncertain. We conducted a meta-analysis of 109 experimental warming studies across seven continents, using natural and standardised plant material, to assess the overarching effect of warming on litter decomposition and identify potential moderating factors. We determined that at least 5.

Background: Proton therapy (PRT) is an innovative radiotherapeutic modality for the treatment of cancer with unique ballistic properties. The depth-dose distribution of a proton beam reduces exposure of healthy tissues to radiations, compared with photon-therapy (XRT). To date, only few indications for proton-therapy, like pediatric cancers, chordomas, or intra-ocular neoplasms, are reimbursed by Health systems.

Introduction: Women have generally lower body size and lean- to fat-mass ratio, lower maximal anaerobic power due to a lower muscle mass, and fewer fast-twitch fibers, although they can show higher resistance to fatigue or greater metabolic flexibility than men. These factors are well known and explain the sex differences in endurance sports such as distance running (10%-12%). Several of these factors-particularly the differences in body composition and skeletal-muscle characteristics-may directly impact vertical displacement and uphill performance.

For people with mental and somatic illnesses, the interpretive process of attending to a multitude of bodily sensations and recognising them as potential symptoms represents daily and 'chronic homework'. Based on 16 months of ethnographic fieldwork in Denmark, this study explores diagnostic work and healthcare seeking among people with severe mental and somatic illnesses. As multiple studies have shown, the transformation process for a perceived sensation to become a symptom is a socially constructed interpretative process highly dependent on social legitimisation and shaped by prior cultural knowledge.
