Comparison of transcriptome responses in blood cells of Atlantic salmon infected by three genotypes of Piscine orthoreovirus.

Piscine orthoreovirus (PRV) infection is common in aquaculture of salmonids. The three known PRV genotypes (PRV-1-3) have host species specificity and cause different diseases, but all infect and replicate in red blood cells (RBCs) in early infection phase. PRV-1 is the causative agent of heart and skeletal muscle inflammation (HSMI) in farmed Atlantic salmon (Salmo salar), PRV-2 causes erythrocytic inclusion body syndrome (EIBS) in coho salmon (Oncorhynchus kisutch), while PRV-3 induces HSMI-like disease in farmed rainbow trout (Oncorhynchus mykiss).

Enhanced warming of European mountain permafrost in the early 21st century.

Mountain permafrost, constituting 30% of the global permafrost area, is sensitive to climate change and strongly impacts mountain ecosystems and communities. This study examines 21st century permafrost warming in European mountains using decadal ground temperature data from sixty-four boreholes in the Alps, Scandinavia, Iceland, Sierra Nevada and Svalbard. During 2013-2022, warming rates at 10 metres depth exceed 1 °C dec in cases, generally surpassing previous estimates because of accelerated warming and the use of a comprehensive data set.

Discovery of thiazostatin D/E using UPLC-HR-MS2-based metabolomics and σ-factor engineering of sp. SE50/110.

As the natural producer of acarbose, sp. SE50/110 has high industrial relevance. Like most Actinobacteria, the strain carries several more putative biosynthetic gene clusters (BGCs) to produce further natural products, which are to be discovered.

Goose grubbing and warming suppress summer net ecosystem CO uptake differentially across high-Arctic tundra habitats.

Environmental changes, such as climate warming and higher herbivory pressure, are altering the carbon balance of Arctic ecosystems; yet, how these drivers modify the carbon balance among different habitats remains uncertain. This hampers our ability to predict changes in the carbon sink strength of tundra ecosystems. We investigated how spring goose grubbing and summer warming-two key environmental-change drivers in the Arctic-alter CO fluxes in three tundra habitats varying in soil moisture and plant-community composition.

Social isolation and loneliness and their association with all-cause mortality. A population-based longitudinal study in Norway: The Tromsø Study 1994-2023.

Objectives: Loneliness and social isolation are associated with increased mortality, but few studies have assessed this association over long time in young adults.

Methods: The study sample comprised 9061 women and 8735 men aged 25 to 69 years who participated in the Tromsø4 survey (1994-95, baseline) of the Tromsø Study, Norway. A subset of the study sample also attended the Tromsø5 (2001), Tromsø6 (2007-08), and Tromsø7 (2015-16) surveys.

Ability of clinical data to predict readmission in Child and Adolescent Mental Health Services.

This study addresses the challenge of predicting readmissions in Child and Adolescent Mental Health Services (CAMHS) by analyzing the predictability of readmissions over short, medium, and long term periods. Using health records spanning 35 years, which included 22,643 patients and 30,938 episodes of care, we focused on the episode of care as a central unit, defined as a referral-discharge cycle that incorporates assessments and interventions. Data pre-processing involved handling missing values, normalizing, and transforming data, while resolving issues related to overlapping episodes and correcting registration errors where possible.

The Effect of Speed Endurance Versus Core Training on The Repeated Sprint Ability of Youth Male Soccer Players - A Randomized Controlled Trial.

The effects of specific training protocols to improve repeated sprint ability are well known; however, the utility of non-specific training for this purpose is doubtful. Therefore, this study aimed to compare the effects of a specific (sport-related) vs. non-specific (general physical development) eight-week training protocol on developing or maintaining repeated sprint ability in soccer players.

Transcranial direct current stimulation (tDCS) enhances cognitive function in schizophrenia: A randomized double-blind sham-controlled trial.

This study aimed to examine the cognitive effects of tDCS and the subjective cognitive improvement perceived by patients with schizophrenia. A total of 173 outpatients diagnosed with schizophrenia were recruited for this double-blind, randomized, placebo-controlled trial. Two different stimulation modes were applied: 2 mA 20 minutes active tDCS and sham tDCS.

Breathing signatures of semantic and phonemic verbal fluency and their impact on test performance in a sample of young Norwegian adults.

Verbal fluency (VF) represents an important aspect of intelligence, in which oral word generation is demanded following semantic or phonemic cues. Two reliable phenomena of VF execution have been reported: A decay in performance across 1-minute trial and a discrepancy score between the semantic and phonemic VF tests (VFTs). Although, these characteristics have been explained from various cognitive standpoints, the fundamental role of speech breathing has not yet been considered.

Investigating the Norwegian eHealth Governance Model: Document Study.

Background: Governments and policy makers struggle to achieve a balance between hierarchical steering and horizontal governance in systems characterized by fragmented decision authority and multiple interests. To realize its One Citizen-One Journal eHealth policy vision, the Norwegian government established a special eHealth board of stakeholders to create an inclusive governance model that aligned stakeholders' interests with the government's ambitions through coordination and consensus. Little empirical knowledge exists on how countries realize inclusive governance models.
