Investigating the Flexibility of H-ZSM-5 Zeolite Upon Adsorption of Coke Precursors: A Theoretical and Experimental Approach.

The flexibility of the H-ZSM-5 zeolite upon adsorption of selected coke precursors was investigated using both theoretical and experimental approaches. Four structural models with varying active site locations were analyzed through density functional theory (DFT) simulations to determine their responses to different types and quantities of aromatic molecules. Complementary experimental analysis was performed, allowing for a direct comparison with the theoretical findings, using thermogravimetric analysis (TGA), nitrogen adsorption (N adsorption), solid-state NMR, and X-ray diffraction (XRD).

Niche partitioning in a periphyton metacommunity peaks at intermediate species richness in midsized rivers.

The trait-based partitioning of species plays a critical role in biodiversity-ecosystem function relationships. This niche partitioning drives and depends on community structure, yet this link remains elusive in the context of a metacommunity, where local community assembly is dictated by regional dispersal alongside local environmental conditions. Hence, elucidating the coupling of niche partitioning and community structure needs spatially explicit studies.

ME patient experiences: Sampling bias limits the external validity of findings.

In a recent paper in , Kielland et al. present a study with the first objective of documenting how helpful or unhelpful persons with ME perceive common services and interventions. The authors recruited participants by respondent driven sampling, a method that aims to produce estimates that correct for sampling bias.

Measuring social integration, treatment, and mortality after substance use treatment: methodological elaborations in a 20-year follow-up study.

Objective: Alcohol and Other Drug (AOD) disorders cause substantial harm. Effective Substance Use Treatment (SUT) exists, but long-term outcomes remain inconclusive. This study used a 20-year prospective follow-up of 1248 service users entering SUT in Stockholm, Sweden, in 2000-2002 to elaborate on how different dimensions of long-term outcomes may be measured by register-based indicators.

Short-term variability of Alzheimer's disease plasma biomarkers in a mixed memory clinic cohort.

Background: For clinical implementation of Alzheimer's disease (AD) blood-based biomarkers (BBMs), knowledge of short-term variability, is crucial to ensure safe and correct biomarker interpretation, i.e., to capture changes or treatment effects that lie beyond that of expected short-term variability and considered clinically relevant.

Background: The reindeer brainworm, Elaphostrongylus rangiferi, is a protostrongylid parasite of reindeer that has caused severe disease outbreaks in reindeer husbandry. E. rangiferi is considered ubiquitous in Norway, though most published prevalence studies are from Finnmark county only.

Network analysis of caffeine use disorder, withdrawal symptoms, and psychiatric symptoms.

Objective: Caffeine Use Disorder (CUD) is not currently recognized as a formal diagnosis in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). However, recent studies within the DSM-5 context have explored this issue. Also, this disorder is closely associated with caffeine withdrawal symptoms, which are formally recognized as a diagnosis in the DSM-5.

Prenatal maternal stress: triangulating evidence for intrauterine exposure effects on birth and early childhood outcomes across multiple approaches.

Background: Maternal stress during pregnancy may impact offspring development via changes in the intrauterine environment. However, genetic and environmental factors shared between mothers and children might skew our understanding of this pathway. This study assesses whether prenatal maternal stress has causal links to offspring outcomes: birthweight, gestational age, or emotional and behavioral difficulties, triangulating across methods that account for various measured and unmeasured confounders.

Association between adolescent obesity and early adulthood healthcare utilization-a two-cohort prospective study.

Background: Pediatric obesity is a growing global health challenge, with long-term implications for individuals and healthcare systems. Existing studies on the association between pediatric obesity and healthcare use in adulthood are limited and often rely on mathematical simulation models. This study aims to provide real-world data on the impact of adolescent obesity on specialized healthcare utilization and costs in early adulthood.

Impact of single nucleotide polymorphisms (SNPs) in antioxidant-enzyme genes on the concentrations of folate, homocysteine and glutathione in plasma from healthy subjects after folic acid supplementation - a randomized controlled crossover trial.

Background: One-carbon metabolism links folate and methionine metabolism and this is essential for nucleotide synthesis in the cells. Alterations in one-carbon metabolism are associated with cardiovascular disease (CVD), type 2 diabetes and cancer. Our aim was to investigate whether SNPs in antioxidant-enzyme genes impact the concentrations of folate in serum (s-folate), plasma total homocysteine (p-tHcy) and total glutathione in plasma (p-tGSH) in healthy subjects after supplementation with folic acid.

General practitioners' clinical decision-making in patients that could have cancer: a vignette study comparing the Baltic states with four Nordic countries.

Objective: Relative one-year cancer survival rates in the Baltic states are lower than the European mean; in the Nordic countries they are higher than the mean. This study investigated the likelihood of General Practitioners (GPs) investigating or referring patients with a low but significant risk of cancer in these two regions, and how this was affected by GP demographics.

Current applications and challenges in large language models for patient care: a systematic review.

Background: The introduction of large language models (LLMs) into clinical practice promises to improve patient education and empowerment, thereby personalizing medical care and broadening access to medical knowledge. Despite the popularity of LLMs, there is a significant gap in systematized information on their use in patient care. Therefore, this systematic review aims to synthesize current applications and limitations of LLMs in patient care.

Differential impacts of germline and adult aggrecan knockout in PV+ neurons on perineuronal nets and PV+ neuronal function.

Perineuronal nets (PNNs) are a condensed form of extracellular matrix primarily found around parvalbumin-expressing (PV+) interneurons. The postnatal maturation of PV+ neurons is accompanied with the formation of PNNs and reduced plasticity. Alterations in PNN and PV+ neuron function have been described for mental disorders such as schizophrenia and autism.

Ex situ living plant collections play a crucial role in providing nature-based solutions to twenty-first century global challenges. However, the complex dynamics of these artificial ecosystems are poorly quantified and understood, affecting biodiversity storage, conservation and utilization. To evaluate the management of ex situ plant diversity, we analysed a century of data comprising 2.

Development of a 3D cephalometric index to grade severity of dentofacial deformity in patients with juvenile idiopathic arthritis.

This investigation aimed to develop a radiographic 3D cephalometric index to grade severity of dentofacial deformity in patients with juvenile idiopathic arthritis (JIA), and to perform a validation against expert evaluations. Data were collected from a population-based Nordic JIA cohort of 240 patients that received a cone-beam computed tomography (CBCT) scan approximately 17 years after onset of JIA. The cohort was randomized into two groups: A baseline group for establishing the index (n = 210) and a test group (n = 30).

Protein N-terminal modifications: molecular machineries and biological implications.

The majority of eukaryotic proteins undergo N-terminal (Nt) modifications facilitated by various enzymes. These enzymes, which target the initial amino acid of a polypeptide in a sequence-dependent manner, encompass peptidases, transferases, cysteine oxygenases, and ligases. Nt modifications - such as acetylation, fatty acylations, methylation, arginylation, and oxidation - enhance proteome complexity and regulate protein targeting, stability, and complex formation.

Reconsidering the Relationship Between Criminal Insanity and Delusions.

This article discusses the relevance of delusions for a finding of criminal insanity. The authors start from the recognition that the psychiatric notion of delusion is considered relevant to criminal insanity in most jurisdictions and therefore integrates psychiatric perspectives to define delusions. The key focus is on the differences regarding how and why delusions matter legally between the Anglo-American and the Norwegian approach to criminal insanity.

Associations of infection burden with Kawasaki disease in a population-based setting during 30 years.

Objectives: The objective of this study was to investigate the role of infections in the pathogenesis of Kawasaki disease.

Methods: The investigation was a nationwide epidemiological case-control study, comprising all cases of Kawasaki disease diagnosed in Sweden 1987-2018. Controls were randomly sampled from the general population, matched on sex, age, and area of residency.

A novel, dominant disease mechanism of distal renal tubular acidosis with specific variants in ATP6V1B1.

Background And Hypothesis: ATP6V1B1 encodes a subunit of the vacuolar H+-ATPase and pathogenic variants are associated with autosomal recessive distal renal tubular acidosis (dRTA) with deafness. Heterozygous variants predicted to affect a specific amino acid, Arg394, have been recurrently reported in dRTA but their significance has been unclear. We hypothesised that these variants are associated with a dominant disease mechanism.

A consensus on the definition of positive animal welfare.

The concept of animal welfare is evolving due to progress in our scientific understanding of animal biology and changing societal expectations. Animal welfare science has been primarily concerned with minimizing suffering, but there is growing interest in also promoting positive experiences, grouped under the term positive animal welfare (PAW). However, there are discrepancies in the use of the term PAW.

Associations Between Sugar-Sweetened Beverage Taxes and Weight Outcomes Among US Adolescents.

Given the recent implementation and preemption of sugar-sweetened beverage taxes across the United States, we aimed to evaluate the associations between sugar-sweetened beverage (SSB) taxes and adolescent weight-related outcomes using data on 364,540 adolescents drawn from 1999 to 2021 district Youth Risk Behavior Surveys. We used difference-in-differences models to assess the associations and the potential mediating roles of SSBs, milk, and 100% fruit juice consumption. We found that a one cent per ounce increase in SSB taxes was associated with a 0.

Probing Autism and ADHD subtypes using cortical signatures of the T1w/T2w-ratio and morphometry.

Autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD) are neurodevelopmental conditions that share genetic etiology and frequently co-occur. Given this comorbidity and well-established clinical heterogeneity, identifying individuals with similar brain signatures may be valuable for predicting clinical outcomes and tailoring treatment strategies. Cortical myelination is a prominent developmental process, and its disruption is a candidate mechanism for both disorders.

Can household energy efficiency dampen crude oil price volatility in the United States?

Even though the effect of oil price shocks on macroeconomics has been extensively investigated, the literature on how efficiency in household energy use affect crude oil price volatility is yet explored. This study unveils whether household energy efficiency lower crude oil price volatility asymmetrically in the United States using the historical and forecast dataset that spans from 1970:Q1-2040:Q1. Applying the multivariate case of Quantile-on-Quantile Regression, the empirical results show that household energy efficiency dampens crude oil price volatility with a stronger connection in quantiles before the median quantiles of crude oil price volatility.
