Next step towards point-of-care molecular diagnosis of female genital schistosomiasis (FGS): evaluation of an instrument-free LAMP procedure.

Detection of spp. DNA in gynaecological samples by quantitative real-time polymerase chain reaction (qPCR) is considered to be the reference diagnostic test for female genital schistosomiasis (FGS). However, qPCR needs expensive laboratory procedures and highly trained technicians.

Depression symptoms, communication and cooperation skills, and friendship: longitudinal associations in young Norwegian children.

Introduction: Symptoms of depression in early childhood have been linked to interpersonal difficulties, whereas friendships serve a protective function.

Methods: In the present study, we examined depression symptoms in preschool age (4 years) in relation to social skills (communication and cooperation), and friendships into early school age (Grades 1 and 2) in a large subsample (= 943) of Norwegian children.

Results: The results indicated that preschool depression symptoms negatively predicted Grade 1 communication skills, which in turn predicted Grade 2 depression symptoms.

The presence of antibiotic-resistant bacteria at four Norwegian wastewater treatment plants: seasonal and wastewater-source effects.

Wastewater treatment plants receive low concentrations of antibiotics. Residual concentrations of antibiotics in the effluent may accelerate the development of antibiotic resistance in the receiving environments. Monitoring of antimicrobial resistance genes (ARGs) in countries with strict regulation of antibiotic use is important in gaining knowledge of how effective these policies are in preventing the emergence of ARGs or whether other strategies are required, for example, at-source treatment of hospital effluents.

Polyoxometalate-ionic liquids (POM-ILs) - a new type of ionic liquid additive family for lubricants.

The focus on energy efficiency to move towards a more sustainable use of resources has intensified efforts to minimize friction and wear in mechanical systems, which account for 23% of the world's energy consumption. In this study, polyoxometalate ionic liquids (POM-ILs) are introduced as environmentally acceptable lubricant additives, for their potential friction-reducing and anti-wear (AW) properties. These compounds, characterized by their complex structures and tunable properties, have been investigated for their tribological performance across base fluids of varying polarities.

Pardon my trench: reflections on the uptake of trenchless technologies in the Norwegian water sector.

Trenchless pipe renewal can be a more cost-, time- and environmentally effective alternative to traditional open-cut replacement. It reduces service disruptions for surrounding infrastructures and is often cheaper, especially when extensive excavation works are necessary, particularly in cold climates, like Norway, where trenches are traditionally deep due to frost security requirements. Still, the uptake of trenchless technologies is still limited in the Norwegian market.

Cytotoxic mechanisms of pemetrexed and HDAC inhibition in non-small cell lung cancer cells involving ribonucleotides in DNA.

The cytotoxic mechanisms of thymidylate synthase inhibitors, such as the multitarget antifolate pemetrexed, are not yet fully understood. Emerging evidence indicates that combining pemetrexed with histone deacetylase inhibitors (HDACi) may enhance therapeutic efficacy in non-small cell lung cancer (NSCLC). To explore this further, A549 NSCLC cells were treated with various combinations of pemetrexed and the HDACi MS275 (Entinostat), and subsequently assessed for cell viability, cell cycle changes, and genotoxic markers.

A preliminary evaluation of a fast, low-cost, and high-throughput nucleic acid extraction method for bacterial microbiota profiling in low-microbial biomass samples.

The respiratory tract is colonized with low-density microbial communities, which have been shown to impact human respiratory health through microbiota-host interactions. However, a lack of fast and cost-effective nucleic acid extraction method for low-microbial biomass samples hinders investigation of respiratory microbiota. Here, we performed a pilot study to assess the suitability of the NAxtra nucleic acid extraction protocol for profiling bacterial microbiota in respiratory samples.

Pervasive glacier retreats across Svalbard from 1985 to 2023.

A major uncertainty in predicting the behaviour of marine-terminating glaciers is ice dynamics driven by non-linear calving front retreat, which is poorly understood and modelled. Using 124919 calving front positions for 149 marine-terminating glaciers in Svalbard from 1985 to 2023, generated with deep learning, we identify pervasive calving front retreats for non-surging glaciers over the past 38 years. We observe widespread seasonal cycles in calving front position for over half of the glaciers.

Validation of Spatial Orientation Screening questionnaire for use in memory clinic patients.

Background: Spatial orientation is required for independent mobility in society. Deficits in spatial orientation can be an early symptom of Alzheimer's disease and other dementias, and there is a need for brief assessment tools to identify impairments.

Objective: The aim of this study was to evaluate the construct and known-group validity of our newly developed Spatial Orientation Screening (SOS) questionnaire.

Adjustable wind selectivity in shearwaters implies knowledge of the foraging landscape.

Understanding the movements of highly mobile animals is challenging because of the many factors they must consider in their decision-making. Many seabirds, for example, are adapted to use winds to travel long distances at low energetic cost but also potentially benefit from targeting specific foraging hotspots. To investigate how an animal makes foraging decisions, given the inevitable trade-off between these factors, we tracked over 600 foraging trips of breeding Manx shearwaters (Puffinus puffinus; N = 218 individuals) using GPS accelerometers.

Cancers attributed to modifiable factors in Norway 2016-2020.

Background: Targeting modifiable factors offers significant potential for primary cancer prevention. For public health strategies, it is essential to quantify the contribution from each factor on a national level. We estimated the contribution of 12 modifiable factors on cancer incidence in the Norwegian population.

Lower Diversity of Amylase-Trypsin Inhibitors and -Released Opioid-Containing Peptides in Ancestral Compared to Modern Wheat Varieties Assessed by Proteomics and Peptidomics.

This study focused on identifying amylase-trypsin inhibitors (ATIs) in seven Norwegian-cultivated wheat varieties, including common wheat and ancestral species, and identifying potentially harmful opioid peptides within the digesta of these wheats. LC-MS/MS analysis of tryptic peptides from ATI fractions revealed that the common wheat variety Børsum exhibited the highest diversity of ATIs ( = 24), while they were less represented in tetraploid emmer ( = 11). Hexaploid wheat Bastian showed low diversity and relative abundance of ATIs.

Lipid Changes 10-15 Years After Roux-en-Y Gastric Bypass: A Prospective Observational Study.

Objectives: To describe long-term (> 10 years) changes in lipid profile after RYGB and to explore the relationship of lipid changes to changes in weight and baseline and demographic parameters.

Methods: The BAROBS study is a prospective observational study post RYGB conducted at three different hospitals.

A national study of in-hospital preparedness for Mass Casualty Incidents and disasters.

Purpose: The current geopolitical situation and climate changes accentuate the importance of health preparedness. The aim was to examine the in-hospital preparedness for Mass Casualty Incidents (MCI) and Major Incidents (MI) on a national level.

Method: A web-based, cross-sectional study of in-hospital preparedness for MCI/MI in Norway.

Endocytic recycling is central to circadian collagen fibrillogenesis and disrupted in fibrosis.

Collagen-I fibrillogenesis is crucial to health and development, where dysregulation is a hallmark of fibroproliferative diseases. Here, we show that collagen-I fibril assembly required a functional endocytic system that recycles collagen-I to assemble new fibrils. Endogenous collagen production was not required for fibrillogenesis if exogenous collagen was available, but the circadian-regulated vacuolar protein sorting (VPS) 33b and collagen-binding integrin α11 subunit were crucial to fibrillogenesis.

NR1D1 Inhibition Enhances Autophagy and Mitophagy in Alzheimer's Disease Models.

Alzheimer's disease (AD) is marked by extracellular beta-amyloid (Aβ) plaques and intracellular Tau tangles, leading to progressive cognitive decline and neuronal dysfunction. Impaired autophagy, a process by which a cell breaks down and destroys damaged or abnormal proteins and other substances, contributes to AD progression. This study investigated Nuclear Receptor Subfamily 1 Group D Member 1 (NR1D1) as a potential therapeutic target for modulating autophagy.

Insomnia in adolescent epidemiological studies: To what extent can the symptoms be explained by circadian factors?

Epidemiological studies show a high prevalence of "insomnia" in adolescents. However, insomnia symptoms are not specific for insomnia disorder. Puberty is associated with circadian delay, which may cause insomnia symptoms such as problems falling asleep and daytime impairments, but also difficulties rising in the morning which is not a hallmark of insomnia disorder.

Study Design: Genome-wide association study (GWAS) meta-analysis with downstream analyses.

Objective: To explore the genetic architecture of chronic low back pain (cLBP) and identify underlying biological mechanisms that contribute to its development.

Summary Of Background Data: Chronic low back pain is prevalent and debilitating, with many cases having no identifiable biological cause.

Rapid Parallel Adaptation in Distinct Invasions of Ambrosia Artemisiifolia Is Driven by Large-Effect Structural Variants.

When introduced to multiple distinct ranges, invasive species provide a compelling natural experiment for understanding the repeatability of adaptation. Ambrosia artemisiifolia is an invasive, noxious weed, and chief cause of hay fever. Leveraging over 400 whole-genome sequences spanning the native-range in North America and 2 invasions in Europe and Australia, we inferred demographically distinct invasion histories on each continent.

Dynamical Disorder in the Mesophase Ferroelectric HdabcoClO: A Machine-Learned Force Field Study.

Hybrid molecular ferroelectrics with orientationally disordered mesophases offer significant promise as lead-free alternatives to traditional inorganic ferroelectrics owing to properties such as room temperature ferroelectricity, low-energy synthesis, malleability, and potential for multiaxial polarization. The ferroelectric molecular salt HdabcoClO is of particular interest due to its ultrafast ferroelectric room-temperature switching. However, so far, there is limited understanding of the nature of dynamical disorder arising in these compounds.

How resistant is anammox biofilm against antibiotics: A special insight into anammox response towards fluoroquinolones.

Elevated concentrations of pharmaceutically active compounds (PhACs) in the water bodies are posing a serious threat to the aquatic microbiota and other organisms. In this context, anaerobic ammonium oxidizing (anammox) bacteria carry a great potential to degrade PhACs through their innate metabolic pathways. This study investigates the influence of short-term exposure to lower and higher concentrations (0.

Density and Viscosity of CO-Loaded Aqueous 2-Amino-2-methyl-1-propanol (AMP) and Piperazine (PZ) Mixtures.

Densities and viscosities of aqueous 2-amino-2-methyl-1-propanol (AMP)/piperazine (PZ) solutions with and without CO are measured from 20 to 80 °C at ambient pressure. Redlich-Kister-based correlations are proposed for the excess molar volumes and viscosity deviation of the binary and ternary mixtures. Empirical correlations are developed to quantitatively describe the effect of CO on the density and viscosity of the aqueous AMP/PZ solutions.

Calcium-binding site in AA10 LPMO from suggests modulating effects during environmental survival and infection.

Despite major efforts toward its eradication, cholera remains a major health threat and economic burden in many low- and middle-income countries. Between outbreaks, the bacterium responsible for the disease, , survives in aquatic environmental reservoirs, where it commonly forms biofilms, for example, on zooplankton. -acetyl glucosamine-binding protein A (GbpA) is an adhesin that binds to the chitinaceous surface of zooplankton and breaks its dense crystalline packing thanks to its lytic polysaccharide monooxygenase (LPMO) activity, which provides with nutrients.
