Cenobamate as add-on treatment for SCN8A developmental and epileptic encephalopathy.

Objectives: Developmental and epileptic encephalopathies (DEEs) caused by pathogenic variants in SCN8A are associated with difficult-to-treat and early-onset seizures, developmental delay/intellectual disability, impaired quality of life, and increased risk of early mortality. High doses of sodium channel blockers are typically used to treat SCN8A-DEE caused by gain-of-function (GoF) variants. However, seizures are often drug resistant, and only a few patients achieve seizure freedom.

RECQL4 affects MHC class II-mediated signalling and favours an immune-evasive signature that limits response to immune checkpoint inhibitor therapy in patients with malignant melanoma.

Background: Cancer immunotherapy has transformed metastatic cancer treatment, yet challenges persist regarding therapeutic efficacy. RECQL4, a RecQ-like helicase, plays a central role in DNA replication and repair as part of the DNA damage response, a pathway implicated in enhancing efficacy of immune checkpoint inhibitor (ICI) therapies. However, its role in patient response to ICI remains unclear.

Do Defense Mechanisms and Dissociation Symptoms Link the Association Between Adverse Childhood Experience and Somatization Symptoms in Faroese Adolescents.

Exposure to multiple adverse childhood experiences (ACEs) is a risk factor for the development and increase in somatization symptoms among adolescents. Defense mechanisms and dissociation may play a key role in the association between these variables. The aim of the study was to analyze the indirect association between direct and indirect exposure to ACEs with somatization symptoms through defense mechanisms and dissociation symptoms in Faroese adolescents.

General Kernel Machine Methods for Multi-Omics Integration and Genome-Wide Association Testing With Related Individuals.

Integrating multi-omics data may help researchers understand the genetic underpinnings of complex traits and diseases. However, the best ways to integrate multi-omics data and use them to address pressing scientific questions remain a challenge. One important and topical problem is how to assess the aggregate effect of multiple genomic data types (e.

The low-lying electronic states of 4H-pyran-4-thione; a photoionization and vacuum ultraviolet absorption study, with interpretation by configuration interaction and density functional calculations for the ionic and singlet states.

Two synchrotron-based studies on 4H-pyran-4-thione, photoelectron spectroscopy and vacuum ultraviolet (VUV) absorption spectra were performed. A highly resolved structure was observed in the photoelectron spectrum (PES), in contrast to an earlier PES study, where little structure was observed. The sequence of ionic states was determined using configuration interaction and coupled cluster methods.

Multiconfigurational short-range on-top pair-density functional theory.

We present the theory and implementation of a fully variational wave function-density functional theory (DFT) hybrid model, which is applicable to many cases of strong correlation. We denote this model as the multiconfigurational self-consistent on-top pair-density functional theory (MC-srPDFT) model. We have previously shown how the multiconfigurational short-range DFT (MC-srDFT) hybrid model can describe many multiconfigurational cases of any spin symmetry and also state-specific calculations on excited states [Hedegård et al.

Organizational strategies of eldercare work and health - Is the daily number of residents cared for over 14 months associated with back pain?

Objectives: The growing care demands of an aging population and a smaller workforce is a big societal problem. Therefore, knowledge on how to organize eldercare work without hampering workers` health is needed. We aimed to investigate if workers` daily number of residents cared for over 14 months is associated with low-back pain in eldercare workers.

Striving for Unity in a Culturally Fragmented World: Nested Multiple Cultural Identifications Associated With Well-Being Through Self-Concept Clarity.

In contemporary globalised societies, global awareness and identification, as well as local and regional identifications (other than national identity), may all become increasingly important for guiding people's sense of belonging and purpose and in turn their self-concept. As the world has become increasingly interconnected, people increasingly identify with various cultures and worldviews within both local and global contexts. Attempts to reconcile these multiple cultural identities can lead to a sense of cultural dissonance as people struggle to integrate these identities into a coherent sense of self.

Cystic fibrosis and the clinical biofilm revolution A survey of the Danish CF Center's contribution.

Biofilm infections are chronic infections which are difficult to diagnose. Biofilm infections are tolerant to antibiotics and the defense mechanisms of the host. Patients with the genetic disease cystic fibrosis (CF) produce viscid mucus in the respiratory tract and therefore suffer from chronic biofilm infections in their lungs and paranasal sinuses.

Facile one-pot reduction of β-nitrostyrenes to phenethylamines using sodium borohydride and copper(II) chloride.

Phenethylamines and phenylisopropylamines of scientific relevance can be prepared with a NaBH/CuCl system in 10 to 30 minutes via reduction of substituted β-nitrostyrenes. This one-pot procedure allows the quick isolation of substituted β-nitrostyrene scaffolds with 62-83% yield under mild conditions, without the need for special precautions, inert atmosphere, and time-consuming purification techniques.

Utilities Associated with the Treatment of Growth Hormone Deficiency (GHD): A Time Trade-off (TTO) Study in the UK and Canada.

Diagnostic potential of blood-based biomarkers in multiple sclerosis.

Multiple sclerosis (MS) is a chronic inflammatory disease affecting the central nervous system (CNS). There is a significant delay in diagnosing MS as the symptoms and tests overlap with other diseases. Blood-based biomarkers, which quantify fragments of proteins involved in MS pathophysiology, have the potential as diagnostic biomarkers.

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.

Bioinspired nanofilament coatings for scale reduction on steel.

Scaling of steel surfaces, prevalent in various industrial applications, results in significant operational inefficiencies and maintenance costs. Inspired by the natural hydrophobicity of springtail (Collembola) skin, which employs micro- and nanostructures to repel water, we investigate the application of silicone nanofilaments (SNFs) as a coating on steel surfaces to mitigate scaling. Silicone nanofilaments, previously successful on polymers, textiles, and glass, are explored for their hydrophobic properties and stability on steel.

Barriers and drivers influencing people's behaviour towards COVID-19 public health and social measures in the Netherlands.

Background: The disease burden of COVID-19 infection, morbidity, and mortality was unevenly distributed across different population subgroups. A one-size-fits-all approach may not reach all groups. Identifying barriers and drivers that influence behaviour towards COVID-19 public health and social measures (PHSM) is an important step when designing tailored interventions.
