The human cathelicidin peptide LL-37 induces autophagy in human macrophages. Different post-translational modifications (PTMs) such as citrullination, acetylation, and formylation impact LL-37, yet their effect on autophagy remains unknown. Thus, we set out to study how the cellular source could impact PTM of LL-37 and subsequent effects on autophagy initiation.

Children with neurodevelopmental disorders tend to have more social difficulties than typically developing children. The aim of the current study was to examine parent and teacher-reported effects of age and gender on social functioning in a large clinical sample of children and adolescents with ADHD, autism, or co-occurring ADHD and autism using a cross-sectional study design. This nationwide clinical sample included 2132 Icelandic children and adolescents (35% girls, 65% boys) aged 5-18 years referred for a neurodevelopmental diagnostic assessment (ADHD and/or autism) in Iceland.

Hypercalcemia in monoclonal gammopathy of undetermined significance (MGUS) presents a clinical challenge since it may indicate progression to multiple myeloma (MM) but could also be due to a multitude of unrelated disorders. To inform the approach to this clinical challenge, we conducted a nested cohort study within the iStopMM screening study. Of the 75,422 Icelanders aged 40 years and above who underwent screening for MGUS, we included 2,546 with MGUS who were in active follow-up, including regular serum calcium measurements.

Light-chain (LC) monoclonal gammopathy of undetermined significance (MGUS) is a precursor of multiple myeloma (MM) and related conditions. LC-MGUS is characterized by free light-chain (FLC) levels outside defined reference intervals, indirectly indicating underlying plasma cell (PC) monoclonality. Next-generation flow cytometry (NGF) was used to evaluate clonal PC presence in bone marrow (BM) samples from individuals with LC-MGUS in the iStopMM study, aiming to assess the predictive value of the FLC ratio for clonal PC presence and its prognostic implications.

Introduction: Medical treatment for termination of pregnancy in the first trimester of pregnancy was first introduced in 2006 at Landspitali. This new method, which replaced surgery, slowly gained ground and now most abortions in Iceland are medically induced. It is therefore appropriate to evaluate the effectiveness and safety of this method.

Nordic nutrition recommendations 2023 (NNR2023) advised for the first time certain amounts of foods from food-groups based on scientific data on healthy and environment-friendly diet. The food-based-dietary-guidelines are intended for adults and children above age two, but children's energy requirement and intake are lower than those of adults. In this review, reference amounts of food from different food-groups are calculated for children to align with the combination recommended for adults in NNR2023.

This report describes the asymmetric synthesis of a focused library of enantiopure structured triacylglycerols (TAGs) comprised of a single saturated fatty acid (C6, C8, C10, C12, C14 or C16), a pure bioactive n-3 polyunsaturated fatty acid (EPA or DHA) and a potent drug (ibuprofen or naproxen) intended as a novel type of prodrug. One of the terminal -1 or -3 positions of the glycerol backbone is occupied with a saturated fatty, the remaining one with a PUFA, and the drug entity is present in the -2 position. This was accomplished by a six-step chemoenzymatic approach starting from enantiopure ()- and ()-solketals.

Exploring the non-Hermitian properties of semiconductor materials for optical applications is at the forefront of photonic research. However, the selection of appropriate systems to implement such photonic devices remains a topic of debate. In this work, we demonstrate that a perovskite crystal, characterized by its easy and low-cost manufacturing, when placed between two distributed Bragg reflectors with an air gap, can form a natural double microcavity.

Rationale & Objective: Low muscle mass is common among older adults and associated with poor prognosis. Quantifying muscle mass is challenging in routine clinical practice. We hypothesized that glomerular filtration of creatinine (GFcr) reflects muscle mass, and previously proposed estimated GFcr (eGFcr), as a practical index of muscle mass in older adults.

Substantial shifts in reproductive behaviors have recently taken place in many high-income countries including earlier age at menarche, advanced age at childbearing, rising childlessness and a lower number of children. As reproduction shifts to later ages, genetic factors may become increasingly important. Although monogenic genetic effects are known, the genetics underlying human reproductive traits are complex, with both causal effects and statistical bias often confounded by socioeconomic factors.

In single-cell and single-nucleus RNA sequencing (RNA-seq), the coexistence of nascent (unprocessed) and mature (processed) messenger RNA (mRNA) poses challenges in accurate read mapping and the interpretation of count matrices. The traditional transcriptome reference, defining the "region of interest" in bulk RNA-seq, restricts its focus to mature mRNA transcripts. This restriction leads to two problems: reads originating outside of the "region of interest" are prone to mismapping within this region, and additionally, such external reads cannot be matched to specific transcript targets.

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.
